HVAC reviews in Carmel, Indiana

I called for service , for our church furnace, and received service the same day . Technician was friendly and professional . We have heat , but waiting on a service part to arrive. The best part everything was under warranty, because of the service contract we purchased , I am glad for the contract. Would I recommend Williams Heating company? Yes ! Thank you for your service .

We needed an electrician to install a fan light and add two receptacles to our bathroom. Martin Lomley’s expertise in accomplishing this work was far above our expectations. He was friendly and direct in quoting us a price and showing pictures (before and after) of the work done. He double checked the completed work - by the way, he completed it faster than his original guesstimate! I would hire Martin again if we needed more work performed!

Our routine maintenance visit went very well as usual.
Matt was a very friendly, knowledgeable and efficient service technician.
We've had Williams Comfort Air for quite a while and we are always very happy with the service and the results throughout the year.

We needed a HVAC as part of the closing agreement on our home. Greg arrived right on time and quickly accessed we needed furnace repair. Chris arrived a few hours later and confirmed we needed a new furnace. He answered all of our questions and provided a clear explanation of the work required. The next day, Gonzalo and Dakota arrived with the new furnace and had it up an running in 4 hours. It was a fair price and we are very thankful for all the folks at Williams!

Had a furnace emergency and called a company (keeping their name off this review) that came out on a Sunday. It turned into a sales pitch and not a solution to my dying furnace. "tech" walked out and left us high and dry. Williams Comfort tech came out on Monday afternoon, and although that first company was right in their assessment of the furnace problem, Roger diagnosed as a second opinion. Explained everything really well without being pushy, listened to my concerns and genuinely cared about the tough situation we were faced with. He helped get it running for the rest of the day- band-aided, and sent the estimator out the very next morning. Blaise came out and like Roger, was very professional, understanding, and didn't try to push to oversell me on our heating needs. Set up the install for the next morning and the installers were very professional and took care of the floors with coverings and shoe booties. Didn't leave a mess to clean. All in all, we went less than 72 hours without heat and Williams Comfort was very responsive and came through in the nick of time. Thank you for getting us back up and running!

Victor, my technician was great. he showed up right at 8am (the window was 8-10am). Performed my yearly furnace inspection and tune-up. He was in and out in and hour. tks!

Geothermal owners...I would reconsider. We have serviced our geothermal system (~10 years old) with Williams for several years and have had a variety of issues that they've navigated with us only to tell us last week that the entire system is improperly set up and will continue to cause the same issues. Each and every technician they've sent over the years finds a new reason the system faults, band-aids it, and we limp along for another few weeks/months before the system faults again. The last technician told us it had something to do with a "worn-out" breaker on our electrical panel. We reluctantly replaced the breaker, only to be met with another fault the next day. With the latest fault last week, the call center finally sent us a geothermal-experienced technician (after I basically begged them to) who spent 3 hours at our home giving me information that we haven't heard in the multiple years we've had Williams at our house. Essentially the faults we've experienced over the years are a result of improper air flow balance. Why no one could tell us that prior is extremely disappointing as we've invested hundreds and hundreds of dollars and time to be left with really no resolution for years.

I have had such an amazing experience with Mr.Plumber. From the original gentleman who came out and snaked my drain to James, Adam, Rob and Kevin who excavated & replaced my drain/sewer line. They were polite, explained everything very clearly, answered all of my questions and truly gave me more advice about how to maintain everything. I will wholeheartedly use them all again and request them by name! It is hard to find companies that don’t try to scam you or charge triple the amount. I truly appreciate it and hope it continues to stay this way as they continue to grow. Thank you all again !!

Update 11/17/25: When purchasing the water heater, evidently your company wisely recommended it be installed with a 1' metal stand on which to sit. This prevents the the bottom from coming in contact with the floor and rusting. Upon inspection today, there's absolutely no rust on the bottom and the unit looks brand new. I stopped validating the tech's findings once I found this.

My 82 year old mother has the company come out annually to drain her water heater (part of the warranty service). I spoke with her last week just after their service. Not only did the tech recommend all water valves be replaced on her plumbing but recommended a $5,000 water softener system. Her plumbing is currently fine with no leaks or problems. The water softener works just fine. Although she is a widow, she's still very sharp and told the tech she wasn't interested. Her final comment was that their techs make these type of recommendations on each yearly visit. This greatly concerns me for the elderly as well as others that put full trust in service techs.

These guys replaced our air condition back in 2022 and they were prompt, professional and courteous. Had an issue with my thermostat and it was fixed immediately. Did a review and we are good until another review is due. You can't go wrong with these guys.

I scheduled an appointment on the website. The gentleman came by exactly when he said would. He diagnosed the problem within 10 minutes and had our heating system back up and running within a few hours. 100% would recommend.

I'd leave more if possible. A bad situation turned into a great experience! The tech was great. He explained everything he was going to do and he assessed the problem with my furnace. He fixed it in a timely manner and the price was fair.

We have been using Williams Comfort Air for over a year to maintain our equipment and when we needed a new furnace they came the next day and installed our new carrier infinity furnace. I love that the furnace is very high quality and quiet keeping our temps perfect and comfortable. I highly recommend the crew at Williams and am very happy with the professional installation.

Matt was very professional and personal. I can tell that he is a true family man and has passion for what he does for a living. He told me everything he was doing and since I had surgery a couple of days ago, he moved a couple of things around in my utility room for me so that he could access the filter in the garage etc.

Thank you Matt and Wms Comfort Airm

We bought a home this fall and had some proactive (as well as emergency) electrical and plumbing work done. Being able to work with one company for multiple issues in our house was really helpful. Communication with Williams is smooth and their proposals and invoices make everything clear what is going on. We had a great experience working with Martin Lomely who helped us figure out our options for electrical work and Jordan and Lee did a great job of executing the plan. And Chris Herrell & Christian McDole both helped with plumbing issues. Thankful to the Williams team!

The entire William’s Comfort Air experience was terrific. Beginning with Roger coming to check out the furnace and then Donnie coming to give us our options for repair or replacing what we had. Donnie was very informative, went over all the options, texted me several times to answer questions Set up the install for the very next day. The install crew gave me a half hour notice showed up put on their booties and went to work. When they were finished they provided me with instruction on how change the filter, and set up and use the smart thermostat. The furnace installation looked perfect and it works perfectly too!!

The Installers were very professional and completed the entire installation within a day. We have Williams Comfort Air / Mr. Plumber service all our HVAC and plumbing needs. Highly recommend.

The technican was very knowledgeable with my type of furnace. He had service my A/C last year. He was well mannered & respected my residence by wearing appropriate gear. He had good recommendations to extend the life of my unit as well making my residence a healthy space. Thank you

I have been a Williams Comfort Air customer for many years.
I feel compelled to share my views regarding a particular HVAC Service Technician, Eric Rogers.

Before using Wms Comfort Air, I was customer of several other HVAC companies for my Summer/Winter Tune-ups, plus misc service visits, new equipment replacement, repair and misc Furnace, Water Heater, Water Softener service and replacement.

After experiencing Williams Comfort Air quality of service, there is no other HVAV & Plumbing company I'll be doing business with in future - I came to this conclusion many years ago.

So, I feel 'experienced' in knowing the difference receiving service from a qualified technician who provides a "Quality of Service" like none other!

Eric Rogers out performs, transcends the work product of all other technicians by far - his work performance is substantially greater than all others.

I have never in decades of receiving service from HVAC companies and their respective technicians, never received the "absolute caliber" of quality service Eric Rogers provides!

Thus, I request him personally when I schedule my twice annual tune-ups, and performing all HVAC service needs for my home.

The detail of Eric Rogers work far-surpasses other technicians I've used, from Williams Comfort Air and including all other companies in same line of work.

Eric Rogers work integrity, absolute detail in cleanliness & all aspects of the job demands ~ exceed expectation ~ consistently.

Time and time again. This technician goes the extra mile, takes those special steps in the process of service he provides ,, that far exceeds others in his line of work.

Williams Comfort Air is very fortunate to have Eric Rogers on staff, and customers benefit as we receive his quality caliber of service and performance.

Thank you for providing this excellent service technician to your clients, he is representing your company well, keeping the company reputation, "Williams Comfort Air" ~ always in same caliber of quality and excellence.

From a longtime customer happy with a technician and company representing quality service!

I have recommended both your company and this technician to family, friends and neighbors.

We just had our furnace repaired by Dayton Underwood at Williams! He was punctual & efficient! He diagnosed the problem in no time & was able to come back first thing the next morning with the part we needed! He fixed our furnace quickly & fully explained his process! Dayton was also able to find out that our furnace was under warranty which saved us a substantial amount of money on the part & repair!! Will def recommend Williams to friends + family!!

I’ve been a customer of Williams Comfort Air for about 10 years. There might be cheaper companies out there but the service is top notch.
However, I have been amazed at the tech Santiago who I’ve had for 2 recent visits. He is extremely professional, very knowledgeable but makes everything easy to understand, gives honest advice, punctual, and on and on. DONT lose this guy to a competitor!
