HVAC reviews in Indianapolis, Indiana

On time, friendly and thorough. System checked out A-Okay (just a minor flame-detector cleaning) after being told by another HVAC company that the whole furnace needed replaced. Highly recommend.

It's late June/early July 2025 and it's 90+ F outside. I've had 5 visits from Williams Comfort Air staff and my NEW outside AC unit and furnace still doesn't work (it continues to ice up). Did I mention that this is a new system that doesn't work more than a few hours? This wouldn't be so bad expect my bedroom temps are 90F all day and night making it impossible to sleep soundly not to mention work from my home office. H. E. L. P. One star review currently. Somebody help. Next appointment (today is Wednesday) is NEXT Tuesday. WThell? I'm a service club member to boot. I just spent $10K plus, my system continues to ice up, I've had 3 service technicians at my home, a sales guy and an install team of 3. Get it right folks.

Technician was very knowledgeable but same issue occurred 2 years ago whereby the regulator broke. Williams Comfort air blamed gas company but it was not their fault. Company process doesn’t allow the technician to properly determine the root cause which delays the fix

Tech was professional polite efficient and was a wonderful rep for WCA. I thank all who help me to keep HVAC running. He deserves recognition. Thank you.

I had Chandler came over on this extremely cold winter day with the same day appointment to fix my furnace. The service was professional. I also learned a lot of tips to keep the heating system running in a good condition.

From Austin (great first impressions of your company, professional, knowledgeable with integrity most important is his genuine care for us offering his assistance after the sale with great follow up! The installation team Ray, Brandon and Alonzo these guys were fantastic and professional in their approach to installing the system, they also showed a great sense of true customer care. Now, if it couldn’t get any better, we had a follow up technician, Jon Farmer. He displayed all the characteristics of the previously mentioned gentleman but beyond the level of customer care outstanding levels of expertise and is coming back to make more adjustments to enhance the systems performance. Hats off to Williams for employing outstanding representatives of your Company. I have experienced such a high quality of technicians.

Our Williams Comfort Air HCAV Specialist Logan Miller is the best technician we have ever had caring for our HVAC system. Personable, caring, thorough and exceptionally knowledgeable,,, and he explains everything in detail so you may fully understand what was done and what might need to be taken care of.

We can always depend on WCA to send out technicians who are kind, respectful and very knowledgeable! Bobby Taylor provided me with detailed information and pictures regarding our Heating System. No sales pressure whatsoever. We highly recommend WCA.

Jonah T. came to our house on 9/30/2025. He was friendly, professional, knowledgeable, and thorough. He did a great job tuning up our HVAC unit and recommending affordable options for an air purifier. We highly recommend Jonah T, and Williams Comfort Air.

I have been a customer with Williams Comfort since 2008! I have never been disappointed in any service. They are dependable, on time and always pleasing the customer's best interest. I would definitely give them a call.

I'm extremely pleased with the service I have received with Williams Comfort Air. I appreciate their monthly plan for maintenance. It works for my budget and it helps me to stay consistent with the maintenance service of my furnace and AC. Their rep Enrique is amazing. He is very thorough and patient in explaining things to me and answering any questions I have. I highly recommend Williams Comfort Air.

Spencer came out to resolve a thermostat incompatibility issue on Carrier furnace I bought from Williams in 2024. Error was made during install, but Spencer was very thorough, careful, and professional taking care of the problem for me. He was polite and friendly and gave me confidence that issue would be resolved. Very pleased with his work. Was done under warranty with no conflict over price.

Let me tell you, folks, this company—absolutely fantastic, the best! They fixed my AC unit, and it was a tremendous job, really incredible. Scheduling? So easy, like you wouldn’t believe, just a quick call and they’re there, boom. The technician? A total superstar, a genius, probably the best in the game—knew exactly what to do, no messing around. And the price? Very fair, nobody does it better, nobody rips you off. Tremendous, just tremendous, believe me.

I had Bryan give me an estimate for a whole home humidifier yesterday, not only was he professional and and very knowledgeable, he was friendly, courteous and able to install the humidifier the same day. Bryan even noticed some issues within my furnace unit that were unrelated to the humidifier install and brought them to my attention. Thank you Bryan and Williams Comfort Air!

Came on time and was polite.
Was very good at explaining the concern and showing the damaged parts.
Was not honest about the cost of repair. Indicated inflated costs for a 1 pole switch and a capacitor. Gave me the inflated cost even after I told him I had electrical experience.

Brandon arrived in the time slot we chose, went about his tasks promptly and when done, showed us pictures of what he did to keep our furnace running smoothly. He was polite and professional. Very pleased with our services.

We used Williams Plumbing May 24, 2024 to replace the trim cover on the tub, waste and overflow – they charged us $662 for the work. Around July of this year (2025), I observed a large leak under the tub in the crawlspace due to insufficient connections between the overflow and drain. Luckily it was caught before there was significant water damage - the leak was cleaned up and Williams was called to fix the connections. The plumber that came attempted to fix the connection but overall determined that the craftsmanship of the entire tub drain was insufficient, leaking, and therefore had to be replaced. He questioned what work Williams had performed previously and was only able to offer a $275 discount for previous work bringing his $830 quote down to $555 for replacement of the drain. My expectation was at a minimum a credit for all previous work ($662) but realistically a completely free-of-charge warranty claim (they claim to have a 2-year warranty on parts/labor) to correct the poor craftsmanship of their previous plumber who came in 2024. Our phone calls to the Williams client care department were not helpful in getting this issue resolved and having them take responsibility for their work. Having reviewed the drain in the crawlspace it is evident that all leaking PVC was performed by Williams (anything past the PVC coupling in the picture) and I would assume a professional plumber should have been able to surmise this as well. Our crawlspace was painted white 2 years ago so its even more obvious that this was their work as they were the only plumber in the crawlspace since then and all the leaking PVC is not-painted.

I’m disappointed in the craftsmanship of Williams plumbing as well as their dishonest response in correcting the craftsmanship. I would not suggest Williams to others nor will be using them in the future.

Very organized company with excellent workers. We cannot be more pleased than with the job Daniel C. did. He was very friendly and efficient.

I've used Williams Comfort Air for several years for our home's HVAC system, and am convinced they're the best in the greater Indianapolis area. They're easy to contact, show up on time, are knowledgeable and professional. A+++

Maintenance plan is a joke. Don't waste your money or time. For almost $300/year they don't do anything without you prompting them to. I expect a monthly maintenance plan to have some sort of preemptive scheduling system to be a partner with me and my homes HVAC needs. I called and made appt. for Nov. furnace check back in springtime but it disappeared from their system and now I have to scramble to find service in a timely manner. The repairs they did in the past were fine but I cant say if they are priced high or low. I just don't know about that. They also are big up-sellers every time they show up for maintenance calls.

Bobby was extremely helpful and friendly. Although he was at my home for annual furnace maintenance, he discovered another issue when it was installed. The location of the humidity pad was not installed in an area where the home owner could not change it when necessary He will be coming back later in the month to fix the issue at no charge.
