The Heat Engineering Co.

Heat Engineering installed a furnace and air conditioner for us. Everyone we worked with was very professional, courteous, and responsive. The price was competitive with other companies. They encountered a unique issue with the installation of the furnace in our older home, and Bryan and his team worked tirelessly, professionally, and with great communication until the issue was resolved to everyone's satisfaction. We highly recommend Heat Engineering.

Zach from the Countryside, IL office did a great job inspecting my a/c and replacing a part. It's a tough job and he was a pro as well as a very nice young man. Kudos to Zach!

I had been a Heat Engineering customer since 1983 (close to 40 years) and decided to try someone new. What a big mistake that was. I used a nationwide service to perform the winter/furnace maintenance who spent very little time on the maintenance and more time trying sell a new furnace to replace my 10 year old system. If not fully replaced, at minimum to replace the blower motor at a cost of $2400 (the normal cost is around $500, and there was nothing wrong with the motor). With all that said I'm back with Heat Engineering for all my future needs.

We’ve been using Heat Engineering for over 40 years for annual maintenance and the installation of 2 furnace/air conditioning systems, so I first offer this as a testament to our complete satisfaction.
The purpose of this response relates to our recent experience. On arising in the morning we found that our furnace had stopped working (this is in the middle of January in the Chicago area).
We called Heat Engineering and in 25 minutes Dan was at our door. He found that our problem was a dust blocked air filter. I make it a habit to change my filters monthly, but failed to do so over the holidays. Also, we recently added 2 room hydrostatic humidifiers which apparently was the cause of the blockage as they emit solid particles along with the moisture (we discontinued using them).
I less than 45 minutes we back up and running after Dan cleaned and checked the system, no need for replacement parts and just a routine service charge.

We've always used Heat Engineering Co. for all our HVAC needs. Extremely professional, competitive pricing, and quick response.
Wish we could post 10 stars!

I love the friendly professional service. Dan was professional and low key about offering future services. Will definitely be using them again.

The contractors from HEAT are always knowledgeable, fast, and helpful. They get the work done well and quickly.

We have been using the Heat for many years. CJ and his team treat our church/school with professionalism and great service.

The Heat Engineering Company has been maintaining my heat and A/C systems for years. They installed my furnace and A/C systems and did a great job! I had them do the duct cleaning, too. I recommend their annual maintenance agreement.

Heat Engineering did a great job. My salesperson Bryan helped me navigate the purchase. Stanley and Jaden handled the AC install and were terrific. Zach did the furnace maintenance. Well done and conveniently handled all in the same day. Thank you!
