Had Efficient replace a humidifier and tune up furnaces the other week. Nothing but good things to say about the experience-timely, accurate, complete. Definitely recommended.

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.

Justin and his team were great. Very nice and easy to work with, and they went the extra mile to track down and solve my furnace problem. I will definitely use them again in the future.

Informative. Matt came by and walked us through everything. Explains how our system works and what may cause problems. Expert advice was offered and we felt comfortable with the entire service along the way. Justin and Chris did the install efficiently and clean. I was happy to hear back from for a follow up.
