So very professional! I bought an air conditioner from them a couple of years ago and woke up to a hot house and texted their phone number because it was under warranty. Willie called me from the hospital!! He had someone out here amazingly fast and they fixed it no problem!! Highly recommend this company

Excellent service! Willy was wonderfully helpful. He was on time, communicated with me every step of the way, and made sure I was satisfied before he cleaned everything up and departed. He even gave me some free pointers on how to keep my system up and running all the time. Wonderful!

I highly recommend the Energy smart. Their staff are very professional over the phone from the representative lady that made an appointment spot to the technician who would say will come to repair name Mr. Walid (Willie). It is a great company. The technician Walid (Willie) was very responsive, professional and knowledgeable. He also tried to help me over the phone with the issue that we were having with heater. Very HONEST, Friendly and knowledgeable. He showed up on time, quickly diagnosed the issue and fix the matter. I have recommended him to my other landlords and rental owners to put his name and number on their book.
