The tech arrived on time and was very friendly. I got a text from their automated service that told me the tech was on his way so I didn’t have to sit around and wait. He serviced my furnace and garage heater and explained what he did when the job was done. They also provided recommendations for a chimney issue that was outside their expertise. Will definitely be using them again.

Good Value. Quality Workmanship. Reliable Forced air Gas Furnace at a fair price. We were referred to Efficient Heating and Cooling from a neighbor. We received two quotes: one for an updated version of our 30-year old furnace and one for 95% efficient furnace. The costs were in line with industry standards so we went with the 95% efficient furnace from Efficient Heating based on our neighbor’s recommendation. The installation went as planned; the workmanship on the sheet metal and air intake and exhaust vending was spot-on. From start to finish it’s just what you expect - quality work, quality product, fair price.

They cleaned the furnace and caught a damaged part causing our humidifier to not work. We were unaware of the problem. They fixed it in no time and everything is working more efficiently now.

Furnace Repair Safety Inspection 

Work with a Furnace Repair Business That Cares

As everyone in the Midwest knows, winters are tough. Not only are they brutally cold, but they are long. So you need a heating system that can withstand the extended period of cold weather. Is your furnace not heating up your rooms properly? It is highly likely that the air filters, circuit breakers, heating units or thermostat on your furnace have worn out. These things will require quick replacement.

Right after one of our heating technicians arrives at your home, he or she will begin determining what is wrong with your heating system. From there, our technician will determine whether your system can be repaired, or if a new system is required.

We only use the best brands and most efficient products.
