HVAC reviews in Indianapolis, Indiana

I received a furnace inspection and tune up as part of the maintenance membership. Joesph was my tech and he was fantastic. He allowed me to watch and learn about my furnace. He gave me tips of how to maintain it or catch problems with its function!

Avant was great. What used to be a dreaded service with another company was very pleasant and informative. Avant explained what he was going to be checking and then reviewed with me what he found. With another company I used for years, I always had a recommendation of several things that needed to be done with the implication that the system would fail if I didn’t. I spent hundreds each visit. Sometimes they even ordered “necessary” new parts and never followed up to to install. The old Technician even joked with another appliance person here that he got a decent upcharge. Avant simply went over each item he checked and showed me how it was performing. There was nothing to improve upon. He was pleasant and efficient. This is an honest company.

Upon inspection it was found that we had a serious crack in the furnace housing. Give the age of the unit we decided to replace both the aged furnace and air conditioning units. The two man team completed the dismantling and replacement of both units in one day. Very instructive of their work with us following the service. Did total cleanup and removal of old units!
They did amazing work.

Victor was very nice and punctual. Somehow the last available slot for yearly maintenance was on 12/31(booked it months ago), and he still showed up willing to do a thorough inspection and explained everything he did and found. I appreciated his service on a holiday.

The maintenance techs are always polite and helpful. I have an HVAC maintenance membership to maintain the warranty that's around $260/year and covers minor repairs, and includes an annual plumbing check. My house is >125 yrs old. This company installed my HVAC and water softener, and also rerouted my kitchen drain a few yrs ago so that it no longer backs up.

Tyler S. arrived early and was prompt and professional throughout the entire visit. He came to my home to complete some electrical work and did an excellent job. He was honest, transparent, and never tried to overcharge. Instead, he clearly explained my options and made recommendations that were relevant and fair based on what I needed. I really appreciate his craftsmanship, reliability, and commitment to fixing the issues at a reasonable price. Highly recommend.

I am very pleased with the HVAC service I’ve had with Williams Comfort Air. The general maintenance was performed by Brandon who was polite, knowledgeable and explained what was being done and answered my questions. After the service was completed, I noticed a slight gas odor. When I called the office to ask about it, another technician, Patrick, came shortly thereafter and tested, etc. He explained that occasionally when cleaning and replacing the parts, a bit of gas might escape. No problems since. I appreciate the immediate response and the professionalism of the technicians.

I don't think that could a hired a better company. The two servicemen were very professional, courteous. Williams Comfort Air, Austin M, and Eduardo ED, did the darn thing. A lot was explained concerning job performance. I was shown trouble spots, and going forward what I needed to do, and look out for. All this time I have been replacing filter, Austin found the real filter, that whoever installed the furnace had fallen into the bottom, which he also told me all you have to do is wash it, and pop it back in. I feel really great about the phenomenal job they performed, Kudos to these two. They showed genuine service about keeping me in the loop

System was freezing up and response to my service call was very quick and professional from booking a tech to the actual visit. Inspection of equipment and recommended solution was excellent and kept my repair cost effective and a plan for future monitoring. I feel this company is professional and trustworthy

The work they performed was fine. We have been a loyal customer of Williams for years (we have a maintenance plan with them). It was when I got on their website to rate them I noticed coupons that I could have used. Yes it is my fault for not checking for them ahead of time. But I called them up and asked if there was anything they could do and the first gentleman I talked to was very straight forward and to the point (his voice had no expression-all business like). He said it was their policy that they do nothing after the sale has been completed.
I asked for a manager and he said he would leave a message for him. About a half hour later a manager called and said they would honor the coupon and give me a refund on my credit card.
I just feel when you have been a loyal customer some rules can be bent at times and you should not have to jump through hoops to get them to honor a coupon they have available on their website.

I contacted Williams Comfort Air to see if they could fix our furnace today (12-29-25) as it kept shutting down. They said they could get a technician to our house today so they scheduled the repair request. Patrick from Williams Comfort Air arrived and was able to fix our furnace and it has been running perfect ever since!!! The lady I talked to to schedule the appointment was friendly, helpful and professional!!! Patrick did an exceptional job repairing our furnace and we are so grateful!!! Patrick was friendly, helpful and professional too!!! I highly recommend Williams Comfort Air for their prompt service, wonderful employees and great prices!!! If I could give them 10 STARS I would!!!

A technician from Williams Comfort Air came to my home today to finish wiring a whole home humidifier to my furnace. The humidifier was already fully mounted to the furnace, plumbing connected, and thermostat wire already run from the thermostat to both the furnace and the humidifier. The only remaining step was to connect the thermostat wire to the furnace and humidifier.

Upon entering my home, the technician immediately stated he could not perform the work because the nearby outlet was being used to charge a vacuum battery, claiming it was, therefore not a designated outlet for the humidifier. I explained that I could simply unplug the charger, but he said he needed to call his boss to see if he was allowed to continue.

After calling, he came back inside and told me the outlet needed to be a 220 V outlet and that I needed a separate disconnect switch installed. My whole home humidifier comes standard with a 110 V plug, which I clearly communicated. He still insisted it needed to be plugged into a 220 V outlet - advice that is not only incorrect but dangerous. I also explained that the humidifier already has a built-in disconnect switch on the front panel that shuts off the unit when opened, but that didn’t seem to matter.

To make the situation even worse, he then told me that even if I had the 220 V outlet and disconnect he was claiming were required, it would still cost $1100 just to connect the thermostat wire because Williams Comfort Air did not install my furnace, and that was the only service option he could select on his iPad.

After providing no service, giving me multiple conflicting excuses for why he couldn’t do the job, and offering unsafe electrical advice, he attempted to charge me a $98 trip fee.

I am extremely displeased with this experience. Between the incorrect technical information, refusal to perform simple work, and an attempt to bill me for a visit that accomplished nothing, I will not be using Williams Comfort Air in the future.

We contacted Northern to get a second opinion after another HVAC company told us we were facing a $3000+ bill to fix our AC. I called in the morning and Tom, the technician, was here later the same day. He was much more thorough and discovered an issue from an unusual modification made by the previous home owner that was completely overlooked by the other company. The fix ended up being much simpler, cheaper, and quicker.

In an non-emergency situation this has been a great company to work with. I found their techs to be prompt and knowledgeable. However, I did not find them accessible over a weekend when my furnace went out. I placed two calls and received no response until Monday morning. I ended up going with another company.

I've used Northern for all my Heating and Cooling needs (and recently Plumbing needs too now) at my properties for the last 9 years and would definitely recommend to all. They have competitive pricing, excellent customer service and very reliable. I've used them for my annual tune ups to installation of new units and have always had positive experiences with their team. I will continue to use in the future for all my properties.

We have been using Northern Comfort System for over 6 years which included a new air conditioner, numerous boiler and plumbing repairs. Gianni, Aaron, Justin and Tom were always professional and explained the work that needed to be done. Gianni also taught me how the boiler worked. Most of all I trust them to fix what needs to be fixed at a fair price.

We needed a new AC system and I called a couple companies out for estimates and Northern was the most competitive on price and was able to get it installed quickly. It was an easy experience from start to finish!

They installed a new heat pump system for my house. Although there was a problem with the install, and I had to call them out twice, they didn’t charge me to come out to address the problems and fixed them within a couple hours of my call.

Northern just replaced my heating and air conditioning unit last summer. They returned yesterday for a routine check of the unit. The technician was in time ,courteous. He wore shoe cvers when entering my home and made a thorough inspection of our hearing and air conditioning system. He was able to answer any questions we had and gave us information about he system and how to make sure we were using it efficiently. Thank you Northern.

Check a/c for summer. Efficient.
Thanks
Checked furnace for Winter. Good work. Won't go anywhere else

2024 - Maintenance performed on unit in March. A/C unit did not run in April. Contacted office. Office sent tech out within a couple of days. Repairs were made. Although paid for labor, part under warranty. Also, great job in replacing garbage disposal. Thanks appreciate the quick response. Still at 5 🌟 ⭐️ 🌟 ⭐️ 🌟.
Thanks

Dustin is the technician that came to both of our properties today to service three units. Dustin was also the one who installed our new furnace and AC in the lower level of our main house a couple of months ago. Dustin is always a pleasure to work with, he is courteous, timely, and always has answers to all of my questions about the HVAC. Dustin has always been careful and mindful of the property and always shoots straight with me about price and timing. I will not use any other provider for HVAC other than Northern comfort systems. We have used them for all of our properties for years and we are extremely pleased with their service , their knowledge, and the overall value.
