Rated 5.0 out of 5 stars based on 34 customer reviews

Fast service. Great prices!

Our AC unit stopped working late at night. I called Ultimate HVAC because of the great reviews I had read. Those reviews are true. I do not write reviews, but felt I needed to in this case. It’s hard to find honest, trustworthy, repair people who do good work at a reasonable cost. Thank you for your great service!

Timely service

My furnace stopped working this morning and my house was freezing. I called ultimate and they were here within 30 minutes and were able to work around my schedule. They had the part in their truck and replaced it for a fair price within 20 minutes. They even answered all my questions while I was watching them install it. I will only call them for service from now on

Furnace problem resolved very quickly

I called Ultimate HVAC about the furnace not igniting and only blowing cold air. They answered very quickly and were able to give me a 45 min time to be at the house. They were there and after looking at the furnace, they said it need a part and were able to get it in less than an hour and have it installed in 20 min. They also replaced the furnace filter for free. Very prompt and good with their time and price! I highly recommend this company!

Very dependable and speedy service

The furnace in our rental unit broke in January. We called and Jonathan showed up within an hour, diagnosed the problem, and let us know the options we had available with quotes the following day. He and the crew replaced the furnace and walked us through all the questions we had. Any furnace replacement is going to be costly, but we felt like we were given honest answers and a fair price - plus the work was done so quickly it made it much less of a hassle. Would highly recommend!


Response from Ultimate HVAC:

Always the best service!

I have been using ultimate HVAC for a few years now. They are very professional and courteous and they always go the extra mile to accommodate my schedule. I travel for work quite often and don’t always have the luxury of availability. I most recently had a situation with my HVAC system. I called at 8 am on a Saturday and they arrived at my home in Northbrook by 10:30 am to diagnose and solve the issue. I wouldn’t think of going anywhere else for all of my HVAC needs.


Response from Ultimate HVAC:

Michael thank you for the positive feedback. We strive to provide nothing but the best service and your appreciation keeps us going.
