Im very happy with the service I received on two occasions. Everything from the scheduling through to performing the service was excellent. The initial technician who came to diagnose and fix the issue was very knowledgeable and efficient. Then the two gentlemen who came to do a full cleaning of my unit were very thorough and overly polite. I couldnt have asked for better. You have a great team! Please pass along my thanks.

Been with this company since last year and couldn't be happier. They know what they're doing, charge fair competitive prices.

It's so much better to go with them than general contractors or other means to try to save a few hundred dollars.

You get what you pay for. I replaced my AC with them a year ago, serviced it at no cost since I have the diagnostics for life package.

They also fixed several mistakes from the previous home owner and a contractor I hired to install the smart thermostat. The furnace and AC would randomly fail at times and I had no idea why. Now I know and everything is working perfectly.

Genuine service. Genuine company.

Excellent service. Excellent communication. The process was smooth. Both AC units were installed and tested and explained.
They both work great without issue.
The men who came were kind and respectful and professional.
Everything was left clean.
I’m grateful for the experience they provided.
Would highly recommend.

Warmest thanks to Liam for his works to resolve the problem of my 10 years old A/C. He thoroughly carried out diagnosis after conversation to me about when the problem occurred and symptoms. Promptly identified where the loosen electric wire should be connected to, hence resolved the problem without any new parts. Meanwhile, he also patiently answered all my questions. He is really a nice and honest guy, and highly competent technician with good knowledge to the product and repair technique. The team of High Efficiency Cooling & Heating kept me well informed about the process since I placed the repair service order. Price is fair, service is excellent, and company is reliable and trustfulness 👍🏻👍🏻
