Phil did a great job of carefully examining all the components of our almost 20 year old HVAC system. He took detailed photos and videos to show me the status. And he didn’t try to sell me anything else! Great experience 10/10System inspection

A few recent Google reviews from homeowners across the metro. We don't edit them.
Efficiency Heating and Cooling came out to our home to do general maintenance on our furnace and heat pump, and also level our heat pump. Tristan was our technician. His work was efficient and thorough. He explained everything he did and told me what Efficiency H&C had to offering the way of maintenance programs. I am very happy with the services we received.Furnace & heat pump maintenance
This was my first time working with this company, and it was an amazing experience! Wayne was super personable, and explained things thoroughly and transparently. The cost was reasonable and that was with the maintenance membership program we joined. Highly recommend this business!Maintenance membership
I definitely recommend Efficiency! On this year's hottest day my AC quit working and Efficiency was able to send a technician right out. He fixed it quickly (luckily it was not a major issue) and now I'm basking in cool air. Thank you so much!AC repair
Tristan was very thorough with diagnosing the issues with my system and walked me through them so I could better understand my options for repair. We’ve had a few HVAC techs look at our system over the last decade or so, and Tristan was by far the best.System diagnosis
Jason came out for an estimate for a heat pump for my house. He listened to what I was looking for function-wise, evaluated the property, gave me a quote with 4 options, and explained the pros and cons of each. He was thorough, friendly, and not at all condescending (women, if you know, you know). Very professional.Heat pump estimate
I bought a furnace from these folks over 10 years ago and was very impressed with their work. I've had them tune up my furnace every year since and it's still the great quality and friendly service. They are dependable and knowledgeable every time I deal with them. I highly recommend them.Furnace install & tune-ups
Efficiency Heating and Cooling is a great company to work with. They gave me multiple options based on personal wants/needs with my 100+ year old house and were patient helping educate me and navigate to a decision. They were prompt, scheduling was easy, very professional, knowledgeable, and walked through with me how my system works once the job was complete. Couldn’t be happier from beginning to end and would heartily recommend them!100+ year old home
Called so many companies to find someone who did duct work beyond cleaning (I had a leak in the duct) and.so glad I got a hold of these guys. Professional, fast, and thorough. Great all around!Duct leak repair
Hire them immediately! Super fair pricing, great service. My Technician, Tristian was communicative and thorough. I tried hiring another company prior and they had me pre-pay, after tons of no shows and shoddy work followed by more no shows I demanded my money back and happily gave it to Efficiency Heating and Cooling.HVAC service
Tristan was very professional. He was on time and explained everything thoroughly. I appreciated the no pressure conversation of future work that could be done with my heating system.Heating system service
What a great experience with Efficiency. From the estimate process to installation, they made everything seamless and easy. When we hit an unexpected snag during installation, they kept us well informed about what was going on how it might affect the timeline. They got everything done and the system is working great!System installation
