We have a service membership program with High Efficiency Cooling & Heating which includes the furnace maintenance. The technician also changed the humidifier filter and recommended a fix to the broken humidifier knob, explaining how it works. Great service!

They responded promptly to my inquiry, had someone down same-day, took care of the issue on the same day as the assessment, and accepted payment on the spot. Great company to work with.

Very thankful to technician Liam. He solved an HVAC concern that other technicians weren't able to fix, and stayed late to make sure the job was completed correctly. High attention to detail and great at diagnosing tricky problems.
Thank you High Efficiency - Liam is an excellent technician

Just wanted to let you know that I had a wonderful experience with High Efficiancy Cooling & Heating. The technician was knowledgeable, helpful and so courteous. He not only diagnosed the problem right away but also did some maintenance on my unit. He also suggested a few tips about programming and other practical instructions to implement which would help with the functioning of my AC. Will definitely use this company the next time I have cooling or heating issues.
