No One Better for HVAC in Chicagoland

After dissatisfaction with another company - we chose to go with the company that installed our Furnace & Air Conditioner - TempCo Jason who came right away when our Air Conditioner froze parts within our furnace and was not working properly. He was very professional & gave us a step by step synopsis of what he had to do and options available to us. I appreciated the fact that he was honest & very informative of what was needed & Not needed. We have used Jason for our yearly check ever since and should we have a problem down the line there is no one better than Jason!!

Saved a “Dead” Air Conditioner

We thought our air conditioner was dead, and would need to be replaced. Jason from Tempco came out on a weekend and diagnosed the problem, replaced a few parts, and got the unit working again! Saved us a ton of money over replacing outright. He was quick, courteous, and made sure to communicate with us along the way. Truly excellent service! Thank you Jason and Tempco, we will be trusting you with our heating and AC for years to come.

Peace of Mind with a Rusty Furnace

I found rust in the furnace and Mark was very thorough in inspecting it, identifying the leak causing the rust and fixing the problem. It was very time consuming and he was very patient and did not rush. Mark went over the process every step; walked me through the problem and how he solved it and by the time he left, I not only felt fully confident and rest assured that the issue is resolved but also knew that it was done in very professional manner. All I want to say is that, if you want peace of mind Tempco is the place to go!
