I just had my HVAC system replaced by Alternative Aire, A Chill Brothers Company. Charles Stewart, the manager, personally inspected my old system and gave me the information I needed to make the right decision for a new system. His team did a great job with the installation: arrived on time, finished in a timely manner, and left the site clean. All at a very reasonable price. Thank you Alternative Aire for a job well done! read more

They did a wonderful, through job. Very efficient, courteous and good workers. they were on time and worked until finished.

We had a new AC system installed last fall (yes almost a year ago). The installation went well and we thought that the job would be satisfactorily completed. Alternative Air looked over our system in order to prepare for inspection and approval by the city of Chapel Hill. It was determined that a 20 amp circuit breaker needed to be replaced with a 15 amp one. After several delays, an electrician contracted by Alternative Air came to our house to perform this swap. He appeared to complete it to my unexperienced eyes. Months later a city inspection was scheduled, and it was determined that the old breaker was still there and the inspection was not completed. That was months ago. Nothing further has been done. I have made repeated calls to the company and am never connected with anyone who can correct this problem. I am always waiting for a call back that never comes. Alternative Air appears to be content to leave the job unfinished, and is clearly avoiding my attempts to deal with it. I am writing this review at least partly in the hope that someone with the company will read it and arrange to have the final steps taken care of. read more

We bought a new unit and as many many others have said it stopped functioning after a year. Getting them to come out usually takes 3-4 days. They've been here 3 times already and STILL it isn't working. DO NOT use this company. They were bought last year by a big company. Not who they used to be. https://thechillbrothers.com/the-chill-brothers-expand-into-north-carolina-with-acquisition-of-alternative-aire/ read more

If your company is going to use AI to answer your phone at lease have someone who knows how to operate I have called your office given message no one replied. I had to call the home office to get them to call the office in Durham to get some one to answer the phone. I am really thinking my house might have some type of fire yesterday it was making loud noise. I planned on contacting the BBB and also will be contacting attorney because people shouldn't sale things they can't honor . read more

We too purchased a new system, only to learn from another HVAC-- honest professional-- that our "new" unit tubing was punctured, no way that could have happened. expensive repair, but now unit runs better-- and with attendant savings, even than new. owner talks a good one, don't believe a single word or promise, read more

We have used Alternative Aire for years. They were very knowledgeable in assisting us with our main HVAC and a mini-split system installed in a remodel. We recently had issues with the mini-split. I got an appointment with Alternative Aire to diagnose an issue with cooling. They sent a technician out who immediately diagnosed that we would need to replace the entire system (installed in 2021). Instead, we opted to have them add coolant to get the system running again until we could find a solution since Alternative Aire serviced our unit in Nov 2025. When the invoice came we found out a company called "Chill Brothers" had purchased Alternative Aire. Their new systems do not have any historical info and I was also told none of the former technicians remained. Needless to say, the system is not working again, less than a week after the service. Be aware when you are contacting Alternative Aire that they are under new ownership and unwilling to stand by the work they previously performed. read more

I had an AC unit quit late on a Friday afternoon. it was hot so I opted for the after hours fee. (I think that the after hours fee that that charge is reasonable.) they came! Thy conquered. I am cool. Great business. I have used them for years. read more

I purchased a new system. It has defective parts. They keep charging me for service visits to identify the parts, then not ordering them. This company has really gone downhill. read more

Excellent maintenance at significant savings when subscribed to monthly plan. Excellent response time and communication.

I have posted reviews of Alternative Aire before, and this is the same. An outstanding company that provides excellent service. Quick responses to my service requests, on-time arrivals, complete resolution of the problems, and then clear explanations by Mr. David Andresen of what was found and any other pertinent info. I would not look anywhere else for these services. read more

Alternative Aire remains my go-to *local* HVAC - not some PE-run chain that rips you off. My upstairs furnace stopped working and they were there the next day to find a loose wire on a control board. Tech arrived early and fixed it quickly and that (cold!) night I had heat again for sleeping. 10/10 read more

Excellent service. The technician showed up on time and understood the problems we were experiencing. He communicated well and work quickly. He resolved our issues and did some additional checks that we requested while he was there. He was very knowledgeable and professional. Overall a great experience for us. read more

My AC was suddenly not cooling on a 100-degree heat index day I am a longtime Alt Aire customer and they've installed a new furnace and a new HVAC for me in past 10 yrs I called them at 12 on a Fri and a tech showed up at 2:30 and had it fixed by 3-was something caused by a lot of rain we've had recently and was a quick fix to a loose wire The house was 80 when AC started cooling again and it was such a relief that they responded so quickly They also do my annual maintenance on furnace and AC I would highly recommend Alt Aire read more

My heater failed just as a cold snap started. I contacted Alternative-Aire, because they'd been great in the past. They were great again. They had someone on site the same day. He fixed and explained the issue. I asked whether the "guilty" part should be replaced. He did not try to "sell" me but said, probably yes. He then asked about warranty, helped me find the right information, and arranged to get the replacement part under the--just barely--still active warranty. These guys are awesome! read more

semi-annual checkup. He was a total professional from start to finish, and it was evident that he was very knowledgeable and highly experienced. One thing he noticed is that one of our units is very overpowered. So, he could adjust the blower to run at a lower pressure except when it's very cold. He was able to have the unit run much quieter as a result, which was music to our ears. read more

I know there was some doubt when Alternative Aire switched to new owners but the service is still wonderful and possibly even better. We subscribed to the monthly plan and immediately saved on work to repair animal damage to our ducts. All service people have been so poilte and confident isn what they do. Cannot live in Durham without air and heat! read more

Alternative Aire provided great service when our heater went out. They came out on a Sunday morning, evaluated it, and got us a "bandaid" solution with auxiliary heat. They got parts and installed them when they came in. The price was lower than I expected. The service person was knowledgeable and nice. I'd recommend them. read more

Technician Joey was timely in his arrival, thorough and informative in answering all my questions during the annual maintenance of my HVAC system. read more

I had a heat tune-up, and the price was reasonable ($129 + tax) and Aaron was friendly and professional. I haven't been cleaning my washable filter, and he recommended using a regular pleated filter, telling me specifically what kind to get. He's going to get me a price to potentially replace the defrost board; however, the whole system is 15 years old, and he said unless we get a lot of cold weather it may not be worth replacing it given the age of the HVAC system. No hard sell whatsoever -- which I really appreciated! read more

Been an Alternative Aire customer for 5+ years now. This was a full heat pump replacement and they were able to do it the first business day after I contacted them over the weekend. Good service as always. read more

I have had the pleasure of working with this company from the office when purchasing a new system to maintaining the system. Everyone I have dealt with in the last 4 years has been professional,knowledgeable,polite, friendly and accommodating. They will answer your calls or emails quickly and show up on time! It is without any hesitation I would recommend them to you. Their quality of service is hard to find! read more

Very professional and honest. Did not push any other services and the cost was fair. I will definitely call them again when I need help with my heat pump. read more

Alternative Aire is a company that is trustworthy, has integrity, and is reliable. It is so hard to find a company that consistently provides their level of service and professionalism. As an added bonus, their technician, Enrique, is an all-around terrific human being! When he was last at my house (18 months ago), my young daughter had recently been diagnosed with cancer. As soon as he greeted me this morning, the next words out of his mouth were, "How is your daughter?". Great businesses employ and retain great people. Enrique is a perfect example of that. I was so happy to see him this morning and touched that he remembered and asked after my girl. (She is doing beautifully after completing treatment just a few months ago!) Thank you, Alternative Aire, for being so wonderful! read more

Enrique was absolutely amazing! Here's the story... we recently had a corporate company (which we were a member of for 3 years) come do a yearly systems check (it was working fine), add Freon, and then noticed the system wasn't working after they left. We had that same company come back out next day to check, they said the compressor was bad and I needed to either jump start the compressor ($500), replace the compressor ($4500), or get an entirely new unit (approx $15,000). I had Alternative Aire come out for a quote on a new unit, but Enrique wanted to look to see what the actual issue could be. Within 10 mins diagnosed that the capacitor was incorrectly wired causing the compressor to not start. Now it works very well and I could not be more pleased with his service. read more

furnace stopped Sunday, called Alternative Aire Monday, first visit Monday -- temporary fix lasted a couple of hours, replaced motor first thing Tuesday, everything fixed & have heat before cold snap tomorrow. Alternative Aire always my first choice. read more

They responded within an hour of my call to their office. Gas heat failed on my old split system. Enrique was the tech and he was fabulous. Listened to my description of the issue. Had the gas heating tubes dismantled in 10 minutes. Cleaned them and then reassembled everything in its proper orientation which is difficult. He let me watch him work and answered all my questions. (I really like knowing how things work and I am modestly DIY capable around AC systems.) This is a real 5 star rating for Enrique and Alternative Aire. read more

This company has given us reliable service for years. Although their prices have understandably gone up recently and things they used to due for preventative service are not included now, so far they have always been helpful in assessing the repairs needed. I would recommend this company to friends. read more

I went a few weeks without the air conditioner and thanks to Alternative Aire for solving the issue. It took 6-7 to get an appointment due to the start of the summer so I just had to wait patiently. I believe it was Kurtis who serviced my HVAC system. He was was kind, polite, and very knowledgeable. He gave me a call ahead of time to check-in before coming over. He was able to fix the issue within an hour. I really appreciate his expertise! The customer service line was also top notch. The AC feels like new! Thank goodness for it! read more

At about 10:00PM, I emailed and completed a form on their website, stating that our AC had died and we were going away, so needed it fixed ASAP. By 8:45AM the next morning, they called and said I would definitely have some to help me by 3:00PM. Very shortly after that, they called again and said someone would be at my house around 9:30AM! At 9:30, here came their truck, and very shortly after that, I was back in business with my AC purring along! I have always had great service from Alternative Aire, and, to me, this time they went above and beyond! I am very grateful! read more

Honest appraisal of the situation/repair. Appreciate their efforts to get things working within budget considerations.

I highly recommend Alternative Aire. They are professional and honest, and best of all they arrive when they say they will. Our AC died on one of the hottest days of the year (on the weekend of course) but they responded to our after-hours request and we did not have to wait until Monday! read more

My wife and I are Realtors and just bought a new home. We had Alt Aire come do a PM check up and they found some questionable components that needed replacement or adjustment. Our system is purring now. Scott and all his techs that have done work for us, and our clients, have been great to deal with. Competent, timely, and reasonably priced, and polite...what more could you ask for? Since our first service in 2012, we've never used anyone else, and never will. Alternative Aire is Excellent!!! read more

Professional, affordable, and informed. Performed furnace/heat pump maintenance service on 2 Rheem units efficiently.

Enrique was informative, kind, and professional as he worked to provide an estimate for a new ac unit. But what's more is that he spent extra time to diagnose the problem and provide a temporary solution so my family didn't have to suffer until the unit is replaced. Alternative Aire was the third company to come out and provide an estimate, but Enrique was the only one who went above and beyond to help us. 10/10 would recommend. read more

Alternate Aire has installed and maintained our HVAC systems for several years now and we have found their technicians well-qualified, helpful, and thorough. If there were any issue with our unit, thermostat, or AC, they were there promptly to repair or replace. We are very pleased with our service! read more

Same day appointments, friendly office to help, techs who what they're doing, and no hard sell when i asked about whether i needed more expensive upgrades, just the facts i needed to decide for myself (didn't go for it). All in all, great experience. They only lose a Star because the part took 5 days to come in the mail, but that prob wasn't their fault. read more

I've used this company for years, including replacing my system 2-3 years ago, with excellent experiences until recently. In August, my AC went out. I made an online request for ASAP service, and followed up with at least 2 voicemail messages (no one picked the phone when I called) over the next several days. Nothing. Not even the courtesy of a reply to say they couldn't help for whatever reason. I even wondered if they'd gone out of business, but apparently not. Another company responded promptly, came out the following day and made the necessary repair. It will be my go-to company from now on. read more

Alternative Aire has been my trusted provider for many years. I live in an historic warehouse in downtown Durham and anything that happens in one person's unit may have repercussions for neighbors when it comes to HVAC issues and potential water leaks from condensation or drip pans. The receptionist is always kind and efficient in scheduling appointments. The technicians are not only knowledgeable but also are gifted teachers! They make very good notes about any issues that are not immediate problems but that warrant follow up at the next visit. They really have helped me keep my HVAC in great shape. Working with Alternative Aire protects not only my investments, but also the historic space that I share so closely with neighbors and friends. Their pricing is very fair and if they consider you to be what they call an "awesome person", you might even get a discount! Really! Give them a call! Sincerely, Pam Rheuark read more

We are so pleased with the quality and service of Alternative Aire. Everyone we've worked with (including those who helped schedule our appointments) have been courteous, helpful, and professional. We had someone coming out to check our HVAC units for years and we never received the kind of helpful information and feedback that Alternative Aire provided. Appointments have been easy to come by and everyone we've worked with has been very knowledgeable. Highly recommend! read more
