Since McCullough's 2018 installation of our Carrier HVAC system we have kept their annual maintenance contract: includes two separate annual inspections for AC and heating. The few system repairs have been covered by the contract, including emergency service over summer weekends. The consistent excellent year round performance of our Carrier system has proven McCullough's annual maintenance fee to be a great value, with peace of mind. Most recently, Linel discovered rodent damage of our AC ducts. After exterminators resealed the house Ian was immediately sent by McCullough to repair the ducts reestablishing the sealed system. McCullough stands behind their warrantied installation, HVAC annual inspections and works effectively with other contractors. We strongly recommend McCullough's installation, maintenance contract, and reliable customer support. read more

Had McCullough install a new unit in December. Initial techs were friendly, people recommended them McCullough provided great guidance on options. Overall we spent ~15k for the unit and install. We haven't gone 30 days without a breakdown yet. Each time it got qc'd, we were told everything was fixed. So far issues have been : - Badly installed drainage leading to water damage - Debris in drain - Refrigerant leak from install - Blown electrical unit. Every root cause was from something done incorrectly during install. We have damaged and unrepaired siding from install, water damaged drywall and paint from the follow on issues. Inspite of these repeated issues from install and failures, each call out for no AC has been treated as if we were calling for the first time and the only proactive communication was for ensuring the city code inspector passed it. read more

Bought a new system three years ago. It breaks down fully at least once a year. It's a lemon. I wish we never bought it. Once again HVaC is shut off with no eta on fix. read more

They sold me a comfort package for $28 per month for a year which included biannual inspections. I sold my house and they would not transfer the package to the new owner, they would not let me transfer the package to my new house and they would not let me cancel. I had to pay off the remaining 7 months of the package. I found it unbelievable that they were willing to lose a customer rather than $160 for which they did no work! Then his reply said he wasn't go to charge me and he did anyway! read more

Yesterday, I was replacing the furness filter and saw a centipede being tangled up by a spider. When my wife came to observe she got a flashlight to spot webs. Looking up she was concerned about open spaces to the attic. We called McCullough and they came out this morning and closed up all of the open spaces. This is three years after they installed the unit and they were so responsive and didn't charge to do this! Mark and Christian were very conscientious about their work, laying down tarps and over shoe slippers while in the house. After the job, Mark offered to use his portable nail gun to add support to the trim that had previously been cracked many years earlier. I am very impressed with the customer service response and remedy to issue, even though the open spaces are not necessay to be sealed. And to go beyond and fix the trim is nothing short of exemplary. read more

Mike is excellent. I have had nothing but great experiences with him and appreciate his willingness to walk through issues and provide additional context. Will continue to request him. read more

We wished we could put ZERO stars, but not an option here. We were with the original McCullough Heating & Air Conditioning team, but they are now gone. They were actual professionals with care, expertise, and professionalism. Today: zero team work and knowledge. Two days ago a technician came to our home smelling of tobacco smoke and making up repairs as he went from one floor to the next. First, we were told it would be $450 for one hour of labor. Then, we needed a new heating strip at $700, even though we're under warranty and with a maintenance plan. That night our heating dropped by ten degrees after the technician fumbled with wiring and reset the panel without our permission. We slept in 40-degree temperatures in our house for two days! We are still awaiting a reply and solution. When I call them, my calls go "offshore" to the Philippines. I cannot speak to anyone local to problem solve. Does anyone work here anymore and with skills and expertise? Who does this with no accountability and responsible behaviors as a business in Austin, Texas? The McCullough Heating & Air Conditioning team. Unreliable and full of jargon on this website: https://coolmenow.com/. Wordiness and skim and scams are core values at McCullough Heating & Air Conditioning. I learned their technicians are outsourced to third parties and under training. Be careful. Keep and stay away from McCullough Heating & Air Conditioning. If you must use their services, ask for printed reports on your system. Take pictures. Hold their wobbly team accountable and responsible. We've proof of what we speak. read more

Like others, we have used McCullough heating and Air for years, and they always did great work. Then my husband went and saw what he thought was moisture, but couldn't be certain if it was from an active leak or not. I called to get someone over and it took three days of back and forth calls just to decide if it was a maintenance or diagnostic type request. I am not a master plumber. I do not know these things. Anyway, they kept calling and so I agreed to whatever they felt was best for this Friday, with the same 8-5 window as others. Nothing all day, and finally a call at 5, only to say they couldn't make it. I called today to see what happened. I was pretty polite, I thought, just trying to see what happened. I was "unfortunately disconnected" twice before getting any answers. I called again, and realized I will not get anything beyond, we were busy and couldn't make it. It would have been courteous to just text/call/email to tell the customer that they would not be able to make the window, so the client could do something else. I agree, things have changed, although they say nothing has. read more

I've used McCullough several times. This week they replaced two HVAC units. They showed up on time with two trucks and four technicians. I'm very pleased with the installation and price. The techs were competent and efficient. Also, they were very nice and friendly. I highly recommend them. read more

Hi If apologies and excuses we sold, they would get 5 stars from me! They totally failed at showing up to my scheduled maintenance appointment. I waited the entire morning and most of the afternoon just to get a text message saying they would not show up until after the window which was from 9am to 5pm! Who can't get their business together and have a better sense of time. It 2025 not 1995! No respect for the customers time nor money. Their excuse for my scheduled appointment was that there were to many emergencies. I waited 2 weeks for this appointment and that's all they could say. They truly will let you down. Pass them up for some other place. Plenty of Reputable places that keep their word. read more

I replaced my three Carrier air conditioning and heating system with McCullough two years ago. I am so impressed with promises made and promises kept. Any issues have been taken care of promptly and professionally. Just had a heating check by Guillermo, and he was excellent - well qualified and professional. I switched from another Austin company who was so inferior to McCullough that I only recommend McCullough to our HOA. Thank you McCullough for professional services, promises kept, and best value in Austin. read more

About a week ago my thermostat started going on and off. Dillon, a tech, with McCullough came to my rescue. He immediately diagnosed the problem and tried to make a temporary fix. Unfortunately a part had to be ordered which delayed the repair, but I trust Dillon to get my AC up and running tomorrow. I have done business with this company for 22 years and have been completely pleased with their technicians and staff. read more

I had a thermostat malfunctioning on a house that I do property management for. I was able to get on the schedule the next day. The technicians did a thorough job troubleshooting the issues and replaced the thermostat, no problems. It would be nice to be able to get a smaller potential work window on the day of the service, but the technicians did call with 30min notice as promised and it was all good. read more

I have used McCullough for 3 new a/c units over the past 8 years as well as for maintenance and service. Today we were told we needed a new compressor for our 8 year old unit. Luckily it's still under the 10 year warranty, right? Sure is, $2400 for labor is all we owe. Ha! He said the quote is based on $500/hour for 4 hours labor. I know doctors and lawyers that charge a lot less. If you want a company that stands by their warranty and charges a reasonable labor rate, go elsewhere! read more

Makayla provided our AC's annual maintenance with outstanding and professional service. She was thorough, gave us information that will prolong the life of our system which we are so grateful. We can always count on McCullough to send experienced technicians with a friendly attitude! read more

Evan Young, Sr. Project Manager, top of the line professional, headed the installation a new HVAC system at our home in Austin, TX. This wonderful Team, including Dillon, Ian, Mike, Joe and Jesse displayed attention to detail, expertise, and such a strong work ethic as they worked together to replace our old system. WOW!!! What a difference this HVAC unit has made to the climate in our home. Thanks to all & also to Ivan who explained possible financing to us. We just passed the City Inspection, here, in Austin, TX & I, once again, want to say how much we appreciate Evan & his McCullough Team. read more

Very unprofessional. Blocked my driveway while working on someone else's system. Couldn't be bothered to move his van. Had to threaten with calling the cops with their dispatch before he finally left. Also talked with the scheduler and he stated "Nothing for their address is coming up" so the Tech was there working off the clock, using the company vehicle and equipment for free. If you want to trust a disrespectful Tech that steals from his employer, be my guest. read more

Their service rep left my attic door open since November 1, 2024 after I explained that the door must be closed or the heat and cold pours through the cabinet doors which are only their for esthetics. I noticed it was harder to cool and now heat the house since their maintenance. Today, Dec 10, we had terrible winds making the temps chill to 35 degrees. I heard the attic cabinet doors banging and when I went to investigate saw that the attic inner door was laying inside the attic. The door was not closed. It takes a ladder and two people to reach the attic and close it properly. I called their service department, three times as I was not getting good vibes about getting this fixed today though they assured me James will be reaching out to fix this. No call. There office will be closing soon. Third time I elevated to management (who hides behind the curtains). Finally James called. He promised that he would find a guy with a ladder and they'd come out and close the attic TONIGHT. He never showed. I purchased service maintenance contracts and two Carrier HVAC systems through this company. I guess they don't care once they have your money. read more

Vladimir was the best player of the day and Tommy on the phone thru the emergency maintenance line I called I don't know why or what happened when Jaiden came over or what happened but I have come to review edit differently with less distaste for the company great techs like Vlad are important I still feel strongly about the bad service of the customer support and scheduling is problematic for sure and definitely needs improvement so glad Vlad was the guy sent out great person and good talking to him very knowledgeable and attentive to the trade and his skills thank you for sending him and he deserves a raise! As far as bad operations and scheduling management is still my view this would be my second time dealing with issues involving bad reps over the phone and no sort of care for customer support and satisfaction even hearing the manager over the phone speak of me as he did " is he giving you troubles?"...I'm not here to make troubles but ti be honest and blunt man about situations I find unreasonable and unsatisfactory. I'm glad my unit is up and running let's hope all is well and house gets back to cooling down again! So far so great! Until the next dreadful emergency service needed hopefully communications and the experience will be better then my last two times Notes: -technicians are great younger ones seems to be the trouble after last two experiences with them -Customer service doesn't seem to be priority of the company but lucky they have great techs who do care like Junior and Vladimir -The scheduling is still a joke 8-10 hour windows to hold people's life's up isn't the best at all with no way of getting a more reliable detail of when and what times most companies are doing 4 hour windows -emergency services are not reliable as some companies that will make the emergency fix more immediate glad they were able to fit me in same day after my animal and child were overheated -piece work is not a good way and leads to bad work sometimes depending on the attitudes of the workers suggesting hourly or commissioned work is more incentivized But all in all , VLADIMIR Was Great And Fixed My Issues And I Am Writing New Revisions Of My Review Because HIS CUSTOMER SERVICE IS SUPURB AND PASSION FOR HIS TRADE WAS OVER THE TOP read more

I would give ZERO stars if possible! I purchased a new AC and furnace in Oct, 2024. In only 6 months, it has stopped working for one reason or another five times!! And it isn't even summer yet! When it failed the fourth time, I requested it be replaced with a new unit as this one appears to be a LEMON. McCullough insists on continuing to send out repairmen. When it failed again last night, I asked again for it to be replaced. In previous repairs they found a faulty compressor (on a brand new unit), then the repairman hadn't reset things correctly, causing another failure. Today they stated I don't replace the filters often enough, although I have receipts showing they are replaced every month (when the AC isn't even being used that much), the most recent only a few days ago. In 15 years with my previous AC, I NEVER had so many repairs or issues! No issues with drainage or filters. No issues with failed parts. No issues with the repairmen. Only with this unit and with McCullough!! read more

It was time for a new AC so I got a few quotes from services that met my criteria and looked good. It was not an emergency, but the system was 20+ yrs old (living on borrowed time!). Coincidentally I was talking with my neighbor just before picking an installer, and he gave a pretty great review for McCullough, especially their service. I typically approach with caution, though. I'd been through several reps from other companies by this time, so I was not expecting much, but scheduled an appointment as a courtesy to my neighbor? Not really sure why I did, but the first impression with the sales rep German /Herman/ was very accommodating and credible. After a little additional product research over the next couple of evenings on the Carrier products (vs. Lennox that I was about to go with, and still would) and McCullough, I had made up my mind to go with these guys on the basis of the recommendation and apparent value in the product and in the warranties and services of McCullough specifically. Installers showed up on time when installation day arrived. There were 3 of them, young polite guys, and they worked like pistons all day in my small attic. At the end of the day they had the areas of the house where they worked as clean as they found it, which was clean. (I'll rebut complaints about the work ethic of the new generation after this experience.) Yesterday we had the follow up visit by a senior technician, Jimmy, who double checked the work of the installers from a couple/few weeks prior. I feel like we are in good hands. We got a two-stage unit, which I would certainly defend as quiet. It's worth noting the condenser is right outside the bedroom windows. I would say that the condenser and the HVAC unit in the house are both very acceptably quiet. Thought I'd interject this note since that was a concern of mine while researching. Also, don't over think the tonnage, SEER, and house energy efficiency (like I have). It can be unnecessarily exhausting. To-date, my neighbor's recommendation appears spot on. His wife stressed the customer service. I would concur so far, and I would further recommend McCullough to anyone looking. Hope this helps. read more

Phenomenal service! Called McCullough on Tuesday morning and they had a technician out same day. James was very professional and explained everything to me as he did his diagnostic work. The next morning he picked up the parts and we were chilling by early afternoon. James made some recommendations regarding regular maintenance including the installation of a UV light to kill and prevent "biological buildup" which you and I call mold. We took his advice and had him install it. What I really appreciate is that James and McCullough were able to work with the manufacturer to allow all parts to be covered under the warranty which had expired just days earlier. This saved us mucho dinero! That is what I call going above and beyond! Highly recommend McCullough to anyone that needs AC service. read more

Great experience from Noah! He was very patient in solving the issue of my hvac unit not heating. He took his time to test every little thing that might cause the issue. He ordered the needed parts right away . On time, reliable and great quality work! I am very satisfied with their business and will continue to rely on McCullough for all of my heating and cooling needs in the future. read more

It's as easy as 1,2,3...McCullough has a great business interface: 1. utmost pleasant and helpful first-line-of -contact re: knowledgeable office personnel 2. quick and convenient scheduling (while their windows of service, day-of-appt, may not include exact time of arrival, it's admirable they reserve most crucial slots for extreme emergency AC /Heat service calls while fitting in filter change requests as the day unfolds) 3. service technician Matt every ounce the professional, calling in advance to make sure he had match/necessary filter on hand, narrowing down appt arrival, calling when 30 mins out. His expertise and efficient [attic] AC handler filter replacement worth every $89 penny!!! *Highly recommend the McCullough team* read more

My air conditioner stopped working suddenly, and I was so happy that McCullough was able to come out the same day, after I called several other companies l, even the one where I bought two 2 systems were not able to come until two days out. They came. They fixed it. The price was fair. Some of it was under warranty. They were able to check that, I'm very happy with the service. My new go to company! read more

McCullough is great. My AC was not cooling and I called late on a Saturday. They apologized that they could not get out that night (I never expected they would) The tech called me that night and told me his schedule for the next day. I had my aunt's 90th Birthday party to attend so asked if it couldn't be before could he schedule me for the evening. He worked really hard and made it here and fixed the issue before the afternoon. I appreciated the fact that not only did I not have to wait 3 days to have someone come out but that they were really trying to work with my schedule the best they could. I know right now they must be so busy and hot, yet still so nice. read more

McCullough just I stalled my new HVAC and I could not be happier. Not the cheapest but definitely not the most expensive. The customer service sets them apart. Aaron and Vinny did the install, Jimmy came out a few days later to do a QC check and my house is ice cold now read more

Well, our terrible McCullough experience continues. Today we find the furnace vent pipe is leaking around it from the installation. No other roof leaks, not leaks there before installation. Still debris and mess in the attic. Upcharge for new ducting "needed" does not work as well as previous ducting. They say we have to pay for a weekend service call and repairs. We are bound to them by contract. Unbelieveably bad $18,000 mistake. Avoid at all costs regardless of what they say or offer. Buyer beware! read more

McCullough got a tough install at my residence. Apparently, the first unit installed was not level causing repeated leaks. The original install had issue after issue, and even caused some damage to my carpet and drywall. While I had my doubts, almost a year later, we have a resolution. I will hand it to McCullough's team. Even though they were handed frustration, headaches, and an impatient customer (me), they eventually sorted it out. They ended up uninstalling, replacing, leveling, and reinstalling the unit, and even took care of my property damages. It is rare for a company to make you whole when installs go sideways and end up costing them money. I gave the company hell because of my own frustrations dealing with the repeated issues. Warranted? Maybe...I will say that it took longer than expected to get the issure resolved. But this was during the Summer, and I have no visibility to the company's workload. I suspect this was the reason. Give this company a shot if you're looking for a new HVAC install. They have proven they actually care about their work and finding solutions to all problems. I went with the Carrier 4-ton and once they figured out the leak, the A/C ran like a champ. This whole journey has been a testament to the team's professionalism, perserverance, and patience. Much appreciated Jensen! read more

McCullough Heating & Air Conditioning - Heating & Air Conditioning/HVAC Near Me - Austin, Texas

I hired McCullough Heating & Air on 08/26/2025 to replace my AC compressor, choosing them based on their good reviews. Two technicians worked about 1.5 hours, and I was charged $2,400 for labor, though I had misunderstood the price during a phone conversation and expected around $240. The company repeatedly insisted there was a "verbal agreement," and no written estimate was provided before work began. They only sent an estimate and job details after I complained, explaining that the $2,400 included refrigerant recovery, labor to change the compressor, picking up the part in Austin, additional refrigerant after the repair, filing the warranty claim, and returning the old compressor to Austin for warranty processing. Even considering these details, this charge is well above standard market rates, where labor for this type of repair typically ranges from $300-$900. When I raised concerns, they offered just a $100 discount and said they would no longer do business with me, while calling my mention of filing a TDLR complaint a "threat." I offered to pay half the labor in good faith, but they refused. I strongly recommend confirming written estimates in advance to avoid costly misunderstandings. read more

Had Matt give me a second opinion from Fox/Precision HVAC, which never addressed my noisy fan issue. In two visits this week, Matt was prompt, courteous, and very well versed in his skills. I purchased an annual service package that will insure that McCullough will be exclusive for my future home air & heating needs. Thank you read more

Have been a customer of McCullough since 2016 and man, do they deliver on quality components and outstanding service. A Mini-split system that we had installed back in 2018 had begun making a waterfall in our dining room because the condensate drain wasn't working properly. I contacted McCullough and within a couple of days they had a real professional, named Matt, who showed up, ready to tackle the job. After a few short tests, Matt was able to deduce exactly what the problem was and begin effecting repairs immediately. I was very impressed by his dedication to the job and his willingness to tackle the obstacles that come along with mini splits. The space to work in is incredibly small and there's a lot packed in to a very tiny area. So my hat is off to Matt. He got the issue resolved by locating a leaking drain tube which was pouring all of the condensation back into the pan. Thus overflowing the pan like Niagara Falls. In the end, the price point was just incredibly good and the repairs were effective and timely. My family will always use McCullough's service. And my hat is off to them. read more

On time and professional, came in and out without issues. He did say it would be best if we scheduled ac check during warmer weather so the refrigerant levels are easier to view. I wish i knew that ahead of time, weather is unpredictable but Ill remember that for next time. read more

I had a new A/C system installed yesterday. Bruce and Alex were excellent to work with. They were conscientious workers, careful while in our home, and attentive to detail. They arrived on time (!) and kept me informed of each step of the process. They told me they focus on one job a day and it shows - they were absolutely thorough. We ended up with a great system. Bruce and Alex are big assets to McCullough glad I got them to work on installing my AC!! read more
