Long Heating & Air serviced my mother's HVAC in August. The price was significantly higher than expected, and the invoice was vague. It didn't clearly explain what was done or why the charges were so high. When I contacted the company to ask for clarification and an itemized explanation, they would not provide a clear breakdown or meaningful answers. Now it's January, and my mother's heat shuts off when temperatures drop below freezing, which is unacceptable for a system that was recently serviced. We hired a different HVAC company to diagnose the issue. They found that the surge protector Long installed was miswired, and they also noted that Long should have changed the return duct filter during the service. Between the overcharging, lack of transparency, and what another professional identified as incorrect installation, I can't recommend this company, especially for anyone relying on heat during cold weather. read more

This is my second year doing dual annual maintenance with Long heating and air conditioning who were the original contractors who installed my HVAC units. Jen coordinated everything perfectly as always,and Steven was the technician that did the full maintenance on the units. I could not ask for more efficient, professional service. I highly recommend them and their staff. Leo Perez read more

I was told by Kyle the technician that my system was broken and needed parts that may not be available so repairs could take months at an estimated cost of $5,000. He recommended buying a whole new system for $11,000 or $13,000 financed. Another HVAC company came out the following day, replaced the motor and fixed the problem at a cost $580.00. Get a 2nd opinion before any major repairs!! Buyer beware! read more

Over the last 3+ years Long has provided mediocre service. I continue to suffer air flow issues. Now the will not show in my area. I would not recommed them and will file a complaint to the BBB. read more

Called Long Heating and A/C last week and scheduled an appointment for 1/5/2026. My husband took the day off for this appointment. On our appointment day, my husband called the company when the technician did not show. He did not get an answer after several calls and then finally Jessica answered (AI) and a message was left. The following day my husband called and spoke to Chrissy about the technician not showing up. Chrissy told my husband that the technician had called and had showed up to our house. My husband told her that he was home all day with the storm door was open anticipating the technician's arrival. Chrissy went on to tell my husband two times that 'someone was lying'. She also took the time to play a 'recording of the sound of a phone ringing' (I assume this was meant to be the alleged call from the technician's phone to my husband's phone) and I can only assume that Chrissy's intentions of playing this recording of a phone ringing' was to tell him that he was the 'liar'. At this point, my husband said that he got frustrated and asked Chrissy why the technician did not come to our door and knock if he was 'allegedly' sitting outside in his truck 'supposedly' calling our home. My husband also told her that it sure was strange that his voicemail could not be heard picking of the call on her recording. Hmmm....sounds fishy to me!! My husband said that Chrissy did not have an answer for that question. First of all, we have a Ring camera at our home, and the technician 'did not' come to our house. We both checked our phone call log and the only calls we saw was from my husband's phone calling the company. My husband said that he ended the call with Chrissy by asking her to have her manager or owner of the company to call him. We have the proof that we are not lying and that the technician did not come to our home and he did not call our phones. Well, we have not received a call from a manager, owner or anyone else after 3 days. We decided to look at the reviews for Long Heating & Air Conditioning and was NOT surprised at the LOW ratings. We read the reviews and decided that we do not want a company like this working for us. I have called another company who was friendly and assured us that this type of customer service would not happen at their company. They have scheduled us for our service tomorrow and we didn't have to wait over a week. They also assured us that we will talk to a 'live' person when we need to call them. It is poor customer service to accuse any customer of 'lying' especially with today's technology such as location data, phone records, and surveillance footage. We would still appreciate a call from a manager or owner from Long Heating & Air Conditioning. Thank you read more

We purchased our new home June of 2022. Yesterday night, I turned on the AC, low and behold, I got nothing. I reached out to Long Heating & Air, got the answering service, attempted quick fixes, nothing worked. Sadly, they were not able to come out that night, they were slammed! Next morning, received a call that our technician was on his way. Our Technician Felix arrived, pleasant and professional. He tested the system and got to work. It took about 1 hour to fix the issue, and test entire system. Our warranty ends next week, and I thank God this repair didn't fall on our watch. We signed up for a reasonable maintenance plan, with priority 24hr. Attention. They come out twice a year, replace filters, run a maintenance check. Or for repairs. Our manufacturer's warranty does not cover labor and other items. Best thing, our technician noticed an opening coming from our window guard placed by homebuilder, and it was defective. Seems the wind pulled it off, and water etc., was/is coming into the house. Contacting builder, and home insurance company next. I liked this technician and I'm a fan of this company. First time using them, and as the summer approaches, glad we are covered. We recommend this company. read more

We came home from vacation, it was one of the hottest weeks this year in South Carolina, to a broken AC. I called on Sunday left a message and they responded first thing on Monday morning and where here Monday afternoon! AMAZING! We needed a part so he gave us some "freeze" (no idea what it's called) so we could keep our house cool while waiting for the part. Part came in and he came early on Thursday - all fixed and ready to go! My technician that came over was super polite, personable and helpful- considering I know NOTHING about AC units. I'll definitely be a loyal customer until I leave South Carolina! We have an AC friend that was disappointed we didn't call him, but we told him the price we paid and he said "that's a good price". So I was happy to hear that! Dependable, polite & budget friendly! Oh, and lastly, the receptionist that called was very friendly - you when you can tell someone is just a happy person? That was her! Thank you for such a wonderful experience! Much appreciated!! read more

Long Heating & Air is a very professional company. The staff is curtious and pleasant to work with. Long Heating & Air does l my HVAC installs and service work on all my properties and new home construction. They are reliable and on time. I am very happy and satisfied with the installations and service. The value the company is great as they pass this on to the customers. read more

They originally installed the HVAC in my home and have been back a number of times to fix the problems with the installation to no avail. The last time I called about a portion of my house getting too hot they told me that they no longer do service calls and to call another company. Imagine that a HAVC company that does no service calls. Anyway I took it upon my 70 year old self to crawl into the attic and look around and to my surprise I found wires that were not even attached to one of the dampers in a trunk line which control the air flow to a portion of my home. Imagine that they never say loose wire hanging around If that is the quality of the work they do no wonder they want you to call another company to fix it. Too bad I can't pick zero or negative stars in the rating. read more

Crooks. They tried telling me parts weren't produced or available anymore. Yet, another company provided them. They said my only option was to replace my entire system to the tune of ~15000. Viper Services is honest and didn't try to scam me. They saved me over 12 grand. Do not trust this company. read more

This is my second time I have to use their service. First of all, someone actually answers the phone in a timely matter. The office staff (Christy and Jennifer) were courteous and helpful. The timely response was amazing since we had a hot spell of weather. Though it was a four hour window, I was glad to get an appointment for the following day. Kyle, the technician was on time. He was competent and professional. Fortunately, it was a "minor" repair and in just a few minutes, my AC was back. We were able to enjoy our evening in the coolness of our home. read more

We had a slow leak in our attic dripping onto our ceiling and it was leaving a wet spot that kept gradually growing larger. Coby found it very quickly and glued the loose pipe back on and repaired the insulation sleeve. I'm very happy with the outcome, courtesy, professionalism, and getting the appointment moved up a day earlier than expected. Thanks so much! read more

NOT Recommended! Looking for someone to do annual service and they recommended a new unit. (Old one was getting a few years on it, so OK.) During installation, they left soda cans under the house and created an ant issue. Claimed they didn't do it and they don't drink soda. Actually said we must have been under the house drinking soda. (We all do that don't we.) Continued with the regular service for a few years and when I called to see why they had not been out, notified they don't support the area any longer. No notification, just dropped. Seeing the trucks around the area and some of the other posts, starting to think they like to drop service after the unit gets a few years on it. read more

Re: Preventive maintenance of the HVAC system Daniel was knowledgeable, personable, informative, thorough, and efficient in providing the service. His calling ahead to let us know when he would arrive was most helpful. Thank you! read more

Great job with the field engineers as always. They provide very clear and concise information as to what they are going to do. Very polite , respectful and professional. The main office also is very courteous and professional. Many of the issues that I have reported have been found to be part of improper installations by the installers hired by the developer. Aside from that I would've given them 5 stars but I had to wait 30 days for a new condenser. Thx. read more

A HVAC with a 5 year warranty, installed by the company, went out in less than a year and a half and I was charged more than what the controller cost from any store for the same model. I was told that parts would be covered but service tech said the controller normally cost around $600 and I am paying $225 as a deductible. The controller is available for less at Grainger. I also had to ask the tech to try the system after and it wasn't working. He had to reset the system. He also left the control panel cover off laying off to the side of my attic unit. read more

We had our fall maintenance done last week. The visit was fairly easy and quick as no issues were found. The technician explained the process before hand and was extremely polite. My only issue was that did not have the proper a/c filter for the 3rd time. my one odd size filter of 12-20 was missing, even the the previous techs said they would write it down so the next tech would have it. He did say he would advise the office and have them bring it to me during the following week. We will wait to see if the come back. If not for this I would have given them a 5 star rating instead of 4. read more

Moved into a home. Was told to call Long to extend the warranty, not an easy process. When I finally spoke with someone, I was able to extend the warranty even have a receipt from them. Called on a Sunday night, to tell them my AC unit stopped working. They said they would have someone call me back and schedule something. If it's Monday-Friday, it would be $89 but if it's after hours or on the weekends $189. Never heard from anyone so called again Monday. Said someone would be able to come out Wednesday. Was told that we were still under warranty, that we would only have to pay for labor. Guy said part would have to be ordered, would take a week. After a week (Wednesday), I called to follow up because I never heard from anyone. Because it's been 87 degrees in my house. Was told my order was marked complete, so part was never ordered. They will need to look into it and will need to call me back. Called back Thursday, because never heard back. Went through 3 more people, to have someone say they will call me back again. Friday, still haven't heard back from anyone so I called again. They told me that I was not under warranty (even though I have a confirmation from them that I had a warranty) and that I am not obligated to use them. Found another company that was able to look up and find my warranty and honored it. read more

!!$355 FOR 20 MINUTES OF LABOR!! If you want to pay RIDICULOUS LABOR CHARGES for "warranty" work then LONG is for you! On the plus side, JR the tech was competent and polite, and Chrissy who discussed this on the phone and offered to have the service manager call me back (he never did) was also very polite. LONG installed the HVAC in our brand new DR Horton home less than 3 years ago so I called them to do the "parts still under warranty repair" when the heater failed. On 1/17 I paid JR $135 for a one-hour diagnostic service call, which was fine with me - a necessary evil. 1/18 JR returned with the part which was under warranty, and took 20 minutes of labor to change out. The charge for the 20 minutes of labor? $355! Yes, $355 for 20 minutes. JR was embarrassed enough about that rate that before he told me he called the office to verify it, and then he showed me on his tablet the picture of the part and the label "$355" that he was required to charge. On 1/18 and 1/21 and 1/28 I called the office and politely spoke to Chrissy each time to ask if I could talk to a manager about a partial refund. She was nice and told me all three times she would pass the message to Jason the service manager but he never had the courtesy to call me to discuss. On the second call she relayed that the $355 included their fee for "picking up the part" (Yep - they will charge YOU for that!) and filing the warranty paperwork with the manufacturer (Again Yep - they will charge YOU for that!). So over two days I spent $490 total on service/labor only (not for parts!) for a repair that only took 20 minutes. I called another local vendor for a quote on replacing that part, and they estimated it would have been $300 for the service call, parts and labor. So I would have saved money by paying out-of-pocket for the part and labor with a less greedy vendor, and that is what I will do from now on. One of my DR Horton neighbors who is a realtor has subsequently told me her agency had already stopped referring their clients to LONG for exactly this reason. read more

The associate that serviced my unit for regular maintenance was courteous, and quick.

Been a loyal customer for 3 years, in fact they installed our furnace. But 2 years now of not returning pre-paid service calls and now a high-pressure sales tactic, and we called it quits. Definitely looking for another service, for pre-paying for services and being a loyal customer doesnt get you anywhere when you need a basic maintenance visit. Calling out Darlene, specifically, who never called back, again pressured us to pre-pay and gave us a date for maintenance 2 months after our original request. Beware! read more

Called to make an appointment weeks back. Gave them my number and assured them someone would be home , becuse my partner works from home and i told them there i will he someone at the house she works from the house. When the day of the appointment arived. They did not show up,citing i did not answer my phone. I explaned i was not able due to me being in a meeting and unavailable. The response,"you could have answered by text" . How unprofessional. They did not show up and blamed the situation on the customer. I reschedualed ,of course at thier convenience, for first thing monday morning ,the lady on theine said the technician lived close by and we woild be his first, monday morning and here we are near noon. Qhen the technician final called he said he is about 40 minutes away.???? Thats ariving past noon And when did they become 4 hour blocks? When i scheduled it was a two hour block. How does this equate monday morning within a 4 hour window? Oh, and please dont chew me out mr technician.we aranged our day twice to accommodate you Very poor and unprofessional read more

I use to subscribe to their maintenance program. On 6/9 a technician, Daniel F. came out for a PM. Part of the PM should have been to clean my drains ( house is 3.5 years old with regularly changed filters.. & yes Long installed the unit), also they have historically replaced my filters during the PM ( I also change every 45 days). On 8/5 I had to request emergency service because my ceiling was leaking on the second floor ( unit in the attic). Ultimately tech from 8/5 says drain is clogged, which is what was making unit leak outside of drip pan, but could not confirm if the drains had been cleaned 55 days ago, but assured me that the drain could clog in 55 days? How? read more

I have used Longs maintenance in services for a number of years and was completely satisfied. On the most recent maintenance service the technician said the Compacitor was slightly out of range (its 4 years old) and the replacement cost would be $123.00 Not knowing what's new compacitor cost I told him to go ahead and replace it. It took less than 5 minutes to replace and did not take any skill set to replace. I looked up prices for new compacitors they ranged from $15 to $25. Beware! read more

I wish I could give them zero stars. This company has literally ripped me off for 3 years. I've had HVAC issues since the first summer I closed on my home. Long has been on service calls to my residence and most of the time they didn't repair anything yet charged me for coming. I've had the circuit board replaced, thermostat among other items and they've charged me for it all. The last straw was today when I was charged 219 dollars for a tech to come out and tell me that I had a short in my unit because improperly wires had burnouts on them. Instead of just replacing the wires, he said he would have to charge an additional 500 dollars for 5 minutes of work. I refused so he left me 219 dollars shorter and still no AC. I ended up fixing it myself with the help of others. Long can literally kick rocks. You have stolen from me for the last time. I wouldn't recommend Long to my worst enemy. There are so many better options. read more

12 Years ago Long Heating & Air installed a totally new system, replacing a 40 year old one. A couple of days later I went under the house to check it out. One of the ducts was laying on the ground air conditioning my crawl space. They couldn't figure it out and had to employ my handy man to show them where to hook it up. For the one year check up they sent this kid who looks at the system and brings back a part. He tells me it's making a funny noise so must be going bad. Usually it's $100. but he has one on his truck and it's $75 if I want to put it in that day. I told him to put the part back. Fast forward to today. No one told me how important a CO monitor could be. I installed one and it goes off in the middle of the night. Long comes and checks the system. No leaks, the kid says. The gas smell is because the system exhausts right next to the crawl space door. He assures all is well. Next day alarm goes off again. I call and ask for better tech. This guy tests using a CO detector. Oh, it's your gas logs, until he took a step toward the register where it really started making noise. He goes down to inspect the system and there are holes in the heat exchanger. My initial warranty had expired, but this part is guaranteed for 99 years . Kid says sorry, better to buy a new system but sorry again, none to be found right now. I call another provider and he finds a replacement heat exchanger and Monday he will move the system to where it should be in my crawl space. NEVER call Long. Their techs are not trained and the second kid didn't care that he was leaving a 70+ year old lady without heat in the middle of winter. I will also lodge a complaint with BBB. read more

EDIT: Tim, the technician, came out and was amazing. He got it fixed fast and was pleasant to talk to. He showed me the issue that caused my outage. If the whole company was upfront and as transparent as Tim, this would be a 5 star company. The worst experience ever. I bought a new home and Long Heating is the company that put it in. From day one it didn't work correct. After requesting them to fix it, they said nothing was wrong. I then went on vacation. I increased the temperature in the house while I was gone. I asked the person taking care of my pets to cut the ac down the day before I return. They cut it down and when I returned home, it was still hot in my house. I looked up some trouble shooting ideas but nothing worked. While I was in the attic, I noticed some of the work that they did and it everything looked like a mess. From the damper valve looking busted to trash being left. I called them on Sunday but they were closed. I called them on Monday. They were closed. I woke up early the next day to call as the opened. I called and no one answered. I called back 30 minutes later and finally talked to someone (about 9am). They told me they would call me back in a hour or two. Around 1, I decided to call them back. They answered but had no record of my call. They told me again they would call me back. They called me back two hours later telling me they can't fit me in and they would try to fit me in ASAP. They didn't have a calendar in front of them and they said they would call back in 20 minutes to set the appointment. I never heard anything back. I called them the next day. Talked to the person that my messages were supposed to be past on to. She hadn't received any messages. So I was at the back of the line again my AC has been out for over 96 hours now. Don't use this company. read more

Terrible, Horrible. Will NEVER use again. We had our AC installed by this sham of a company when the house was built through Mungo. We have had continual problems. We have to call them out at least twice a year - and the house is only 3 years old. It's cause damage to my ceilings where the unit has failed to cut off from all the water in the pan. The pipes freeze constantly and we have to go days without AC to get that unfrozen again. It was never installed correctly and they refuse to do anything but patch it - and they charge us just to come look at THEIR PROBLEM. I can tell you this - I will NEVER use this company again and if a builder is using them, I will look elsewhere. Had I known what kind of shady business this was when we were building with Mungo - I would have never, ever bought this house. NEVER. Terrible. Horrible. DO NOT USE!!!!!! EVER!!!!!!!!!!!!!! read more

Technician was on time, accomplished routine maintenance efficiently and changed filters. No problems.

I have worked in the home building business for 26 years and the builders I have worked for use Long Heating & air to install their HVAC units and wiring. Although my house was built back in 1992, I thought I would have them come out to do my fall/spring checks on my unit. Which they did and gladly took my money, but I have off the wall filters sizes that they do not stock. I asked in the fall to please order me some to no avail, then in the spring the tech brought me the right size filter. (guess they had them then). I also had a T-stat installed provided by them at my cost and now I'm having issues with it switching back and forth from cool to heat. I came home Sunday 6/30/19, when it was 94 degrees outside with my heat being on and set at 82. I'm guessing I didn't change to heat and set on 82! I called on Tuesday, because of my work scheduled didn't have time to call on Monday. I spoke with I think Shanna ?? Was told she would check the schedule and call me back (was told a tech would be out on Wednesday)...NO RETURN PHONE CALL. Something again came up with my work schedule, so I called back Wednesday morning only to find out NO APPT had been scheduled and no filters ordered. I had to give the exact same information as I did on Tuesday. So here it is Friday 7/5 and was told someone would be out between 8-12, at 11:55 I called and was told no tech had been assigned my service call. Wow, it's now 3:35 and was told they would be here shortly! Never again will I contact Long Heating and Air! Guess what I still pull all residential permits for DR Horton and Meritage Homes! Sure hope they don't treat those new homeowners as I have been treated. I'll never contact them again! Once burned never burned again! Good luck to the homeowners that have to use Long Heating and Air! Please by all means contact me for my input.... skfpermitting@outlook.com Shout out to Tim and Chris, but only had them drop off my filters, will have someone else check out my T-Stat, it wasn't their fault, but the fault of the office for me having to sit around all day! And my T-Stat should still be under warranty, but at this point I don't care! read more

I was told they would be coming between 1-5pm, showed up at 8:45pm. My A/C wasn't working. they did get it going but didn't check to see if the heat worked so I had to have someone else come out to fix it. They installed a thermostat that was not compatible with my unit. The second company was less expensive. I called to explain and was told they would look into it and get back to me, it has been over a week and I haven't heard from them. Would not recommend them read more

Long Heating & Air installed the unit on our new built house. We have been trying to get them to fix issues since day one. We have had poor air flow, huge temperature differences between rooms on the same floor. the first time they came out, they told us we had to have all the doors trimmed at the bottom before they would do anything. Once that was completed, they came out and installed a diverter to try and equal out the air flow and room temperatures. We waited and while it did help, it did not solve the problem. The next tech that came out, said it was because we had a kink in one of the lines. He said he did not have the parts to fix it but that he would order them, and someone would be back to installed. The next appoint was two weeks later from 8 - 12. The tech showed up right at 12, with I only assumed was his girlfriend (who staid in the vehicle). The tech told me up front that he was not replacing the line. Once the second tech arrived to help him (which is why I thought the girl in the truck was not an employee), he finally climbed into the attic to "take a look". Then told me it was not a kink in the line, that he was the expert and the other guy was not, that it was actually the thermostat that needed to be replaced. So again, we would have to wait because he only does the lines, so someone else would have to come back to install the thermostat. He also told me that I should keep all my doors open, blinds closed and get room darkening curtains to help with the temperature issues. 3 weeks later I had to follow up again because no one had been out to replace the thermostat. When the next tech finally came out he told us that there was nothing wrong with the thermostat and the last techs equipment must have been bad and that nothing was wrong with the system. After talking down to us he told us he needed proof of the issues. That we needed to take pictures with timestamps showing temperature readings. So in the end nothing has been done, but tech blaming the last person and we have to wait until it get hot again or winter, so we can send proof of the problem. If they did not install the unit I would not be using them for anything. read more

Ooo buddy. After a week of calling and being told, "someone will call you to schedule" I finally got someone to schedule me a time between 1130am and 2pm today, June 25th 2019. At around 215pm, I called again was told the tech had run behind but I was the next house. At around 330pm, I called a third time (actually like an 18th time if you count the week before) was told the tech would be out soon. Shocker 415pm rolls around and you guessed it... NO TECH. I called again the guy in the phone calls the tech tells me the tech went out of order and he is finishing up his job and would be here in 20 minutes and offered to wave my $85 charge for having them come out. Time is now 520pm the business is closed and no tech. Avoid this company at all cost. If we didn't have a warranty on parts with them through our home builder I'd have called another company. You best believe when tomorrow comes around and they open up I'll be the first one on y'alls telephone line. I want to speak to the highest manager/owner you guys have...PRONTO. THIS IS BY FAR THE WORST CUSTOMER SERVICE I HAVE EVER RECEIVED. TO CONTINUE TO LIE TO A PAYING CUSTOMER AND THEN NOT EVEN SHOW UP AFTER THEY HAVE SAT AT HOME ALL DAY WAITING FOR SOMEONE IS ABSOLUTELY DISTASTEFUL AND DISGUSTING. read more

We contacted Longs over three months ago to replace a part for our air conditioning unit as they are the contracted vendor through Mungo homes. The technician who came out was great, although now it's been so long we can't remember who he was. They had to order a part and were going to contact us when it came in. We never heard from them so we began calling ourselves. They answered once and said they would return our call, which never happened. We have called countless times over the span of three months and emailed and still no follow up. We eventually went through another local air company who completed the job in a few days for several hundred less. read more

I purchased my new home in October 2018, and Long installed the unit for the builder. I decided to continue to do business with them, so they come and service the unit twice a year. They also change the filters for me on alternate months since the returns are in the ceiling. I've been nothing but pleased. The office staff has been great to deal with, and the technicians have been some of the nicest folks ever. Our unit continues to run great almost a year later. read more
