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.

AC was on just not blowing cold. It was 90 in the house and 100 plus outside. My home warranty couldn't come until Monday its Wednesday btw. So I went down the phone book. lees ac could come out. Gave me a BS quote of 1800.00 and fed me a bunch of crap. I kicked him out and went to work to see what I could do about this AC .Energy Smart Fresno called me from looking on line. Willy came out fixed one part, explained it to me. Said if it didn't work will try something else. 400.00 fix with service fee and now our AC is blowing Cold. Excellent job my family and I appreciate it.

Willey at Energy Smart did an excellent job repairing our A/C. We have a home warranty that we went through and had not heard of Energy Smart prior. Willey was excellent communicating with us on scheduling, repairs needed, timing, and expectations. I would recommend Willey at Energy Smart. He went the extra mile to get our A/C back up and running. Thank you so much!!!!
