Living in Chicagoland, heating and cooling are a necessity, and utility bills are always a cause for complaint. Who isn’t looking for ways to reduce household energy consumption? At Chicago HVAC Repair Doctor, we specialize in straightforward solutions and highly recommend the outstanding benefits of a wifi thermostat. As home improvements go, a new thermostat is inexpensive, doesn’t require a messy installation project, and delivers a lot of bang for the buck.

Expert WiFi Thermostat Installations

The modern generation of technologically advanced thermostats aren’t just pretty to look at. They are wonderfully user-friendly, can trim heating and cooling costs by up to 23%, and simplify temperature management. Just consider the savings provided by a device that automatically caters to your schedule, conserving energy when you’re away and welcoming you home to ideal comfort. There’s also the added advantage of room sensors to eliminate hot and cold spots, the ability to access operation through your smartphone, and instant troubleshooting alerts.

Customer Reviews

Our customers speak for us

Joshua and Paul were very professional and showed up on time. Josh walked me through my entire inspection and answered all the questions I had for him. Customer service has also been excellent, which is a huge plus! Prices are fair, and I highly suggest using this company for any heating or HVAC needs.


Amazing customer service. We had an emergency and they came out very quickly. I think we were right outside of their perimeter but because it was cold and our heating went out they sent someone to fix the issue. Alan was our technician. He is very knowledgeable, efficient, and very straight forward with the issue. I really recommend this company and look forward to working with them in the future.


Highly recommend Chicago HVAC Repair Doctor, Inc. I recently moved into a condo, and had AC maintenance done. The Chicago HVAC Doctor team was incredibly responsive from the first scheduling call. They provided text updates the morning of the scheduled maintenance, and took the time to walk me through every step of their process. I will be calling them again in the fall for furnace maintenance!
