Great service and they actually do the job right. If you want cheap they aren't the ones to call but if you actually want the job done the right way and not the cheap way, they aren't the guys you want to call. read more

Edit: Unfortuntely I have to edit this review as the follow up to this plumbing job has been horrific. Following the plumbing job, I never received an invoice for the work. After having another leak in the same spot 6 weeks later, I called Casteel to follow up with the invoice and pricing. Once I recieved the invoice, I noticed that I was charged over $650 to just cut the ceiling to see the issue. Yes, over $600 to CUT THE CEILING, which took 5 mins at most. Then, the repair was performed, which was another $600. I have now tried to contact Casteel for 3 weeks to get an explanation for the $650 charge and I cannot get anyone to talk to me. I have been transferred, hung up on, transferred to full voicemails, promised calls back in 12 hours, etc. Noone is willing to explain or ever give me the time to tell me why my simple 6 x 10 in ceiling cut was labeled as a "level 2" cut - which means it was in a dangerous or inaccesible location, prompting the $600+ charge. Long story short, had the second plumbing leak fixed for $350 by another company, compared to $1200+ from Casteel. DO NOT USE CASTEEL PLUMBING. You will be overcharged. Go to literally any other plumbing company. I hope this finally prompts Casteel to reach out to me, as they can see that I've called 10+ times and there are lots of notes on my account regarding this concern. Had a great experience with Casteel. We were able to get a quick appointment and the tech was prompt and polite. Donald gave a very thorough explanation of the possible plumbing issues. Once we had a plan, he worked efficiently. He was friendly, polite and professional. Highly recommend the company. read more

Underhanded sales tactics, disconcerting and frankly offputting experience. I had an air conditioner that was cycling on and off and failing to deliver cold temperatures. I called Casteel and they immediately sent Miguel to come diagnosis the issue. Miguel arrived promptly, quickly sent up his diagnostic tool and saw that the refrigerant was low. He then took a look at the coil and blower in the basement. His diagnosis took roughly 10 minutes. He then told me that the repair would be north of $4,000 and that he also recommended replacing my Goodwin furnance. I knew enough to know that whatever the problem was it was not a multi hour (and certainly not a multi-day) fix - and upselling me on a new furnance was completely out of place given the issue at hand. I then tried to pay Miguel with my credit card in hand for the $99 diagnostic charge. He then said he needed to write up a quote for the recommended repairs. I waited twenty minutes as he sat in his van in my driveway apparently writing up a quote. I approached his van, again with credit card in hand attempting to pay the $99 fee, he said he needed more time for the quote. After an hour, I reapproached the van to pay the $99 fee - Miguel said it would be more time. After two hours of Miguel running his van in my driveway, I'd had enough. I approached the van with my credit card in hand and demanded to pay the fee and have him leave. Miguel then fumbled with his phone/tablet and was unable to present me with an invoice or a way to pay the fee. He said he would email me a payment link. Strangely even after all that he would not leave my driveway. I ended up having to call his supervisor Kyle to get Miguel to leave my driveway. Miguel then parked at the top of the driveway and then moved to the neighbors house for the next hour. The van left a nasty oil stain in my driveway. I don't what kind of business Casteel runs where they have their techs parked in customer's driveways, running their vans, doing nothing related to the customers needs but it did not leave me with a good feeling about doing business with Casteel. The next AC repair vendor I called charged me $800 to fix the issue in a few hours. read more

Technician came over to tune up our HVAC systems on Oct 15, 2024. He said that the attic system wasn't working properly and that it was resetting itself every 10 minutes. Also that the heat exchanger was cracked and required replacement. The Attic system was installed in 2013. He showed me a picture of where the metal pieces were welded together and said there was a small crack in the circular weld area. He said the same thing about the heat exchanger in the basement HVAC system. That one was installed in 2010. He told us if we didn't get the heat exchangers replaced, carbon monoxide could leak throughout the house. I have relatively new (3-year-old) carbon monoxide detectors on all three levels and none of them has ever gone off. He told us replacement heat exchangers would run about $4,200 each. Today, 10/30/2024, I had a second opinion. Another HVAC technician came out today and looked at the attic and basement systems and said they were working properly. That the heat exchangers were not cracked. And that the systems were working properly. The cheap tune-up offer is just a way for them to get into your house and lie about your HVAC system. Their technicians are either poorly trained or trained to scare you to get money out of you that you don't need to spend on your HVAC system. I don't like leaving bad reviews, which is why it took me so long to post this review. But today they texted me another "tune-up" offer to come out to my house after I told them not to contact me any further. They will never come back out to my house. read more

If I could give negative stars, I would. We purchased an overpriced HVAC system from this company, that's still under warranty. From day one, every time the heat turned on-everyone in the house experienced horrible sinus issues, trouble breathing. We installed a humidifier on furnace-it's still happening. The AC unit is the worst I've ever owned. Our old units would cool the house down comfortably. We only have about 1400 square feet. This unit, will not cool our house down on hot summer days. Our old units did . They keep telling us it's due to the high temperatures, but Georgia always has high temps in the summer. I've lost track of how many service calls we've had, & every time they give us some excuse & shrug their shoulders. Save yourself a ton of money & as many headaches & avoid this company like the plague. read more

When I called Casteel for services, an illiterate sounding female would not allow me to speak with an expert about my problem. They place ALL issues into one category - which is not the case. In short, it is TOTALLY impossible to get old-fashion good service. It is a trap to force people to pay for a house call. DO NOT CALL THEM - NO EXPERT WILL COME TO THE PHONE! read more

Horrible experience, still 14 days with no response to the warranty claim. Buyer be warned, they do not intend to withhold warranty and in fact if you call in they won't let you speak to a manager. Good luck and avoid at all costs. read more

Caution with Casteel. They have cancelled 2 appointments with me during the window of time that Casteel was to show up. They cancelled midway into the appointment on a weekday and then again today after I spoke to someone this morning and they assured me the technician would show up as scheduled. Its completely unacceptable to to cancel scheduled appointments during the time they are to show up. And, Casteel has done it twice to me in 3 days. I have an existing contract so I'm "stuck" with Casteel, but use caution if choosing to use Casteel. They don't honor their appointments or their customer's time! read more

AWFUL! 5+ days to get scheduled for an emergency repair...and I'm a Comfort Plus member. Supposedly Comfort Plus provides priority" scheduling. Tech was supposed to be here between 2 and 6 pm today...its now 7:40 pm and not a peep. Stay way from this company and their scam Comfort Plus program. read more

I made an appointment to have my new 9000BTU Mini Split AC checked for a leak and charge it. I was told $99 for the service call and diagnosis. I agreed. The tech called and asked what my expectation was. I said it was a new unit, but my friend installed it; he bent the copper line, and it sprang a leak. He repaired it, so I want it checked for leaks and recharged with R34. He said, " Well, you are looking at $1800 to $2000. I asked him if he thought I was stupid. read more

The technicians receive a bonus based on how much revenue their truck does for that month I was quoted $2400 with a replacement of a capacitor in the quote two times and I only have one air conditioner. There was nothing wrong with the capacitor. I got a second opinion I didn't need a new motor and a new disconnect box on the outside. The total cost was $700 for both of these, please buyer beware of this company. Last year they came to my house, sprayed a chemical through my air conditioner to clean it out. When I now understand I could've just used water. The chemical has spotted a large section on my hardy plank. I let it go, but I should've disputed that please please do not use these people unless you just really wanna spend your money always get two or three opinions. I use Champion and they were very honest and fair. I don't know what is wrong with this company that they can gouge people like that I am a widow and a senior citizen and I just want to warn others that may be unlimited incomes. Thank you for your time. read more

Quick and fast... may not be price-wise, but when you need them, they will be there. You can also book on line which is a plus

They got me. Somehow I got talked into a "in before the end of the year special". The sales guy is slick. But that's not who does the work. And they outsource their financing to a sleazy west coast company who harasses their customers and only exists to make lives miserable for you and profitable for them. I didn't even want financing - I just needed until Friday! I paid that ridiculous loan off immediately and they kept calling. I wrote them to stop, they paused. Now they call again. To add insult to injury, we used a different company for our other system (complete overhaul) for less than HALF the price of this piece of crap wind tunnel Casteel put in. I wish I had never called Casteel and I'm telling everyone I know to beware. read more

Purchased new central AC from Casteel. Still under warranty and not cooling. Tech scheduled, but never showed or called. Contacted office and requested supervisor - told no supervisors. Days later got call back, another tech visit scheduled. Tech stated coil is leaking and needs to be replaced. Another tech visit to replace coil. Several days later and AC is not cooling. Called office and requested suoervisor/manager. Told there are none, but would receive call back in 10 hours. Days later, no callbacks, and no working AC I would not recommend doing business with this company. read more

On the website, it states 24 hour service and that a technician is available today. Our air system has gone down for the FORTH time in two years where we supposedly got one of their top-of-the-line systems. We called last night and Casteel stated that noone could come out until Sunday, even though we told them we have elderly people living in our home and again, this is the FORTH time where the air completely stopped working. Last night it was 77° in our house and only 71° outside. I fear how hot it will get in here today, and they've told us they have no one to help us until tomorrow. read more

The capacitor went out on our downstairs outside unit. Had Casteel come out and replaced it. The tech wanted to replace the capacitor on the second unit because they are the same age. He changed $490 to replace one and wanted another $490 to replace the second one. I told him no we will wait until it stops working. We never go upstairs but we noticed a few days later that the upstairs was getting hot. Bought a capacitor from Amazon for $19.0 for the second unit. The thing is that it wasn't the capacitor on the second unit the tech from Casteel had unplugged the thermostat connection on the second outside unit so it wouldn't come on. NO WAY I will ever call Casteel again. read more

I had a new AC unit installed 3 years ago. June 2, 2026, my system stopped working. A technician came out and repaired. 3 days later the system stopped working again. Technician came back out and discovered the pan was cracked and new pan was needed. As of 7/7/2026 the new pan has not been installed. I have requested a return call several times. I get the same response some one will call me back. I ask for a manager, I'm told they are busy and will call me back. In over a month noone has responded to my calls or provided an status update. I have lest messages for Sandra and her manager Alyssa in customer relations. This company has the worst customer relations department. The install team was great. But if you have a issue and have to follow up with Casteel customer relations do not expect a call back. I don't understand how customer service can be so bad and Casteel feel this is acceptable. read more

In May, I hired Casteel to replace my furnace, air conditioner and breaker box for more than $24,000. Shortly after technicians left, I realized my wine cooler was not running. It was an old machine that didn't hold temperature well, so I assumed it had died and I bought a new one. It didn't work either. I tested the outlet- no juice.I called Casteel and they told me I was covered by warranty and they sent Matthew, who told me he fixed the outlet. But when I plugged in the new cooler, it did not work... again. I called Casteel once more; they asked if I wanted Matthew again, but I requested a different electrician. Ahead of the appointment, I got a call....from Matthew. Although Casteel had again assured me my warranty covered the service, Matthew told me the service would cost $300. I objected, stating that Casteel had assured me it was covered by warranty. Matthew told me I was wrong. When I continued to object, he told me to "calm down" because he would not come if I "showed attitude." When he continued to say this to me, I hung up on him and called Casteel to request another electrician. They sent Loshane Grant, who was competent, courteous and honored the warranty. He fixed the outlet and told me the problem was that it had not been connected at the breaker box. A faulty installation of the new breaker box and a rude, condescending and incompetent electrician who couldn't fix it and insisted I pay him to try again is not what I expected of Casteel. read more

Revised Review for 11/07/2025---Was told my assigned tech was still in a team meeting this morning; calling in at 07:35 AM EST. Called Back at 10:35 am same day and after a 12 minute phone hold -- got to speak to a dispatcher who said he is still in that same team meeting. Waiting a phone call from supervisor Curtis to confirm what took place. Original Window was between 8am - noon 11/07 and time of this review is 10:40 AM. read more

I want to start off with the fact that I think this is the location that is servicing me in McDonough, however; I'm not sure. My experience with Casteel in general has been disappointing. I have used them for our home for the past two years and every time the weather changes, my heating and cooling system doesn't work. We spent over $2,000 last spring and here we are again needing service. Every time they come, we are spending money and breaking down again in six months. We even made an appointment for a specific person to come and they got that wrong too. Now we have to wait two more days with no heat. This is unacceptable. read more

Casteel is a great company overall. My most recent experience with their service guy Jason was excellent. He went above and beyond.

I have been a long-term Casteel customer, but no more! Casteel replaced the toilet tank bolts 5 weeks ago. The toilet tank started leaking again and Castell come out to fix the problem. It was obvious that the rubber washer had failed - the center was ripped out. The plumber charged me for replacing these bolts and the failed washers. I'm not a plumber so I don't know if the washer failed because they were defective or because the plumber installed them incorrectly. In either case this is clearly a Castell problem that I should not have had to pay to fix the problem again. It was Sunday, and I called Castell and asked to talk with a manager but was told no managers were available. I ask for a manager to call me back when they were back in the office. I have not received a call back from a Casteel Manager. read more

in less than a year after purchasing an expensive HVAC system I have had 3 inconvenient visits from servicemen to try and fix why my heater won't stay on to reach the set temperature. Now I am waiting for my 4th inconvenient visit to install a return air vent that should have been installed with my unit initially. Won't use them again read more

Terrible Experience! Beware. My neighbor recommended Casteel. After I gave her and her husband my feedback, they were so embarrassed and decided no more business or referrals for this company. The first technicians at my house didn't do the service I paid for. I was tricked into believing they did. My house was very cool for only four days. I called Casteel and asked for the manager. Didn't get a response until I called again the next day. The manager, Justin, sent a tech supervisor who did a leak search and gave me a quote. They agreed to deduct the money I already paid from the first service. I researched the cost for parts and labor. The quote I received was so inflated. The worst part of this experience was the tech supervisor left my house feeling hotter than when he came in and the attic door was wide open. He didn't close the door or clean up. That was unprofessional. Before he came, the inside temperature of my house was 77 degrees. Low cool air with low velocity was blowing from the vents. However, he turned off the AC in the attic, reset it and hot air started blowing after he left. The inside temperature rose to 82 degrees. I had to turn off all thermostats. It's still 82 degrees and uncomfortable for sleeping. As soon as I discovered the house was getting hotter, I called and asked for Justin (the manager) a little after 4:00 pm. Dispatch said he was gone for the day and no one else could help. I wasted valuable time (days) and money with Casteel, so I called another HVAC company. A company listed in the "Best Pick Reports - 2024", "Verified Home Services - 2024" and "TrustDALE Certified Services Guide" books. I spoke with the manager and shared my disappointing experience with Casteel. He gave me some advice and a price range for parts and labor. On the higher end, Casteel's quote was $2,000 more. That's to replace an evaporator coil. He's sending a technician to my house for the next day to review the equipment and order the parts. They will also help get the house cool while I wait for the service to be completed. I work from home so it's extra important to be comfortable (and not sweating) as much as possible. No one - especially single ladies - should trust Casteel. They are a rip off. read more

Casteel has always done well by me and my family. Today Shaun Wharton and another plumber whose name I cannot recall came to install a toilet. This is the second toilet Shaun has installed. Both were professional, courteous and efficient. I was able to keep working while they did the installation. I am very pleased with the toilet and the price was great also. If I needed another toilet, which I do not, I would call Casteel. Thanks guys!! read more

Extremely Dissatisfied I am extremely dissatisfied with my experience with Casteel Air. Paid over $16,000 for a brand new HVAC unit for my 1,750 sq ft home. My air conditioning unit has not been functioning properly since being installed, and despite having five different technicians come out to assess the issue, there has been no improvement whatsoever. It is never reliable. Cuts off in the middle of it night for no reason. The main floor of my home is inconsistent and currently at an uncomfortable 78 degrees, while the upstairs soars to 88 degrees, despite having the thermostat set to 67. Making the upstairs unusable. Their solution? I was told I would need to purchase a completely separate unit just to regulate the temperature upstairs -- a solution that seems more like a way to avoid fixing the problem than an actual fix. To make matters worse, the company no-showed for an appointment after I took my child to another location, so they were willing to come in the house. I've spent countless hours on the phone with customer service and even more time waiting during technician service windows that led to nowhere. The final straw was having to leave my home to sleep elsewhere during the first week of school -- an especially critical time for me as a teacher -- simply because my home was too miserable to stay in, despite calling five times in five days to have the issue resolved. Casteel Air has failed to provide competent service, communication, or any meaningful resolution to my issue. I can not recommend this company, and I strongly urge others to consider alternative providers. This has been an incredibly frustrating and exhausting experience. read more

I have already written reviews about this Company. This is an updated review. Based on several factors, we would have ended our relationship with Casteel Plumbing and Heating long ago. However, we had them install our new HVAC unit about three years ago and they hold the 10 year parts and labor warranty. Our much vaunted Lennox HVAC unit continues to give us problems especially during the hottest and coldest times of each year. The more this has happened to harder it has gotten to get a tech out to fix it in a timely fashion. We froze for a WEEK without any heat during high 20's to low 30's weather last winter, waiting for Casteel service. We pay every six months for a tech to Check our HVAC system. We scheduled our summer checkup months ahead of time. On the day of service, May 2, 2025, we were notified that Casteel was too busy and we would have to reschedule. The next date was June 2nd, again we were told on the day of service that the tech was not coming and we would have to reschedule. New service date: June 9th. AGAIN, we were told no tech was available. Every time I asked to speak with a supervisor/manager and every time I was told none were available but they would be informed so they could call me back. Never happened. In fact, in 9 years and perhaps 20 requests to speak with a supervisor or manager, there has NEVER been one available! On perhaps 3 occasions a supervisor did call, always days later and always after the situation had already been resolved. Save yourself a lot of money and frustration. Shop around for your heating/plumbing/electrical needs. When we got our latest hot water heater, I compared prices and found Casteel to be the highest locally. Reviewing Casteel's estimate, I did some comparison shopping. I chose one of the most expensive parts on their list. I found the identical (professional quality) part for a fraction of their quote. I employed another company, got a great, high-quality unit for just over half quote from Castee. In fairness, we have found their techs knowledgeable and professional. However, if they tell you they will pass on your concerns to their supervisor and request that they call you.......don't expect to get that call. Expect prompt professional, polite service when you are paying for it. Expect a lot less when it's covered warranty service. read more

Casteel and management: I am sure you all are not short of jobs and the opportunity to make money but coming in with a high number for a repair when the rest of your competition is half the price and than trying to lower it by 1/3rd does not show honest business practice. I doubt you will win my trust back reason for which you are getting a 1 star! read more

Casteel is a dishonest HVAC company that provides lousy service. Promises are not kept, quotes don't match invoices. Once they adjust your invoice, Casteel prices are higher than their competitors. They claim to be focused on customer service but nothing could be further from the truth. Worst experience I've ever had working with any type of service provider. read more

I got a new air conditioning system from this company in April. One of my issues before changing the system was that the old one cooled, but I had a huge temperature difference between upstairs temp and dictate downstairs. The salesman told me that a new system would overcome this issue. Since I have had the system, I have had 6 visits for various issues and not one tech has addressed the issue in total. The last tech who was here, sa mid that his super would be contacting me, that wa a going on 3 weeks ago! I am very unsatisfied with the way I'm being treated concerning my issue! read more

Casteel sold me on a HVAC system that they described as an upgrade from what I had. turns out it's actual builder grade. I asked them to replace a heat pump and had no idea they were quoting me builder grade standard ac machines. Their installers are great so you will believe you are getting a great system from a quality company. But, you are receiving way less than what you are paying for. Definitely, explore other companies and pay attention to what they are selling you in the invoice not what they are explaining to you in person. read more

Too many cancelled appointments. I have received calls at the last minute notifying that the technician cannot come to my house. I usually take off from work in order to be available when the technician arrives. This is very frustrating! read more

Poor communication. Casteel was quick to respond and send a sales rep to provide HVAC system replacement quotes: one for a conventional system and the other for a more modern system. I was considering the latter option, but apparently it was decided that that system was not compatible in my home, which was a dubious and unexplained conclusion on the part of Casteel. Also, no one ever called or texted to let me know. I didn't discover this situation until I did my own follow-up with the company. I also had two "managers" reach out to me, neither of whom ever followed up again with additional information or options. I'm walking away. read more

Casteel worked on my neighbor's a/c and trashed our yard, blocked our driveway, and refused to do anything about it when we complained to their project manager. They are arrogant, self-centered pricks. Never, ever do business with jerks like them. read more

I am so tired and frustrated with this company. We had our house for sale and decided to get our FOUR units serviced. We scheduled the service and the showed up and had no problems...UNTIL the service technician told us that 3 of our four units were cracked showed us some pictures and he put giant orange stickers on our units saying that they were not safe to operate. It was JULY and he told us they were very dangerous to operate and that if we turned on our heat, we would probably die of gas inhalation. they immediately sent a sales person to our house the next day, who I quickly showed the door and told them never to come back. We peeled off the stickers and called another company to service the units. We did not mention the previous service we scheduled another company to come out and they promptly serviced all of my units at a fair price. No mention of cracks or danger. We went from over 30K for replacing units to a couple of hundred dollars. Oh, by the way, we have ran our sytem all winter and we are still alive. Fast forward a couple of months, and they called me to service my units. I asked them to take me off the list of their calls, as I never want them back in my house again. They asked me what happened, I explained and I was promised that I would never get another phone call. A couple of months later, sure enough another call. I impatiently told the man on the phone that I did not want any mor calls, or I was going to take time out of my busy day to write a review such as this one. He assured me that I would not be bothered again but was genuinely upset about the problem. He asked me to explain what had happened. He again, promised me that he could assure me that he could make sure that I would not be bothered again. He also asked if I would be so kind as to let a customer service Manager call me because he was sure that the company would want to make it right. He has seen them do amazing things and that he has even seen his company build houses, replace systems, etc. I was told that tech no longer worked there. I was touched that someone actually cared that I was put into a panic about the situation. A few days later i got a call from the service supervisor who assured me that she would make sure that I was never bothered by Casteel again. However, she did see the pictures with cracks. She of course, could not guarantee that this was my system in the pictures, etc. She also did not understand why during the July appointment that he told me to fix my heating? I then proceeded to get upset because I was wondering if there really is a problem with my system. I was more upset by that phone call then before. I am still trying to sell my house. She then said she would have a technician that loves to solve problems call me? I said if that is what you want to do, fine. I really just want to know that I don't have problems. The tech called me a day later completely unaware of my story and not really sure what he was supposed to do? The call then got disconnected and I did not receive a call back. i let it drop. I was just tired of wasting my time with these people. A few days later, i got a text saying that I am on Casteel's list of customers and that they are having a special. REALLY? I just want to be left alone by this company. That is all I really want, and I can't get that. After reading reviews, I suspect they will pretend to care. I have no idea why they are bothering me....This company is scamming the public. I have no idea as to how they stay in busness. read more

A few months ago I booked an appointment to do fall maintenance on my 3 HVAC units. I was told at that time that if I signed a yearly contract (svc in fall and spring), I would pay $ 59 per unit for a total of $354 yearly. I booked the appt. When the technician arrived today, I was told the company no longer offers this service (PPP plan). I was upset that I was not grandfathered just this once as I was told. BUT, I called another company and they gave me a quote for the same service AND a senior citizen discount for a total of $ 334 yearly! Obviously, I am now a customer of another company! read more

It's unfortunate to read these reviews and hear the frustration about specific issues and employees. However, last night, I had a completely different experience. Casteel sent Samuel to inspect my unit, and he was incredibly transparent about the issues and the necessary steps to prevent my AC problems now and in the future. I had another company out, and I wasted a lot of money and time by adding a duct that barely produced any air. Only to find out I needed an entirely new unit, he showed me things that didn't even come up in my inspection report. I'm incredibly grateful for his knowledge, customer service, and understanding and compassion. When I call in I'll be asking for Samuel, every time! read more
