• I honestly have never worked with an HVAC business this nice and this professional. The young lady who answered the phone was very helpful and sweet. Cedric, who repaired my AC talked me through the entire process. He explained what was needed and how to prevent problems in the future. Exceptional. Thank you.

• Awesome company..I recommend this place I had a young man name Brent ...explained everything to me was real detail and honest ..I am staying with this company..ask for Brent or Arron highly recommend. AFTER HAVING A FALL OUT WITH THE young female on the phone i have decided to revise my review...i have decided to change my service for the person who was extremely rude and unprofessional to my phone call...i was upset ...they never answer thier calls first of all and when asking about a service call tht was not attended too ....the call became a back and forth disagreement.sorry for the change but the office personal was very very rude and unhelpful I will no longer be part of thier

• Jesus,Brent, Misael did an excellent job fixing my heater. They were very thorough in finding the problem and fixing it. They also went above and beyond by cleaning what needed to be cleaned and opening my air vents even more for air to flow thru. They were also prompt and came in the scheduled time they said they would be here. They also said if a problem occurs, to call them back and they would return . Highly recommended to call if you have any issues with heating and cooling systems

• We got a prompt response from Diaz Services when our air conditioner was blowing warm air. Brent was a compete professional and took the time to show me the issues within the unit. The cost to fix the problem was fair and I will definitely use Diaz Services in the future.

  Mo K.★★★★★

• I am extremely impressed with the speed and level of service from the team at Diaz Services. My refrigerated AC unit went out and with our hot El Paso days I needed help ASAP. I spoke to Mr. Diaz at 11AM and by 2PM a service tech arrived at my home to fix the problem. Within the hour our AC was repaired, cleaned and inspected for a reasonable price too. I would highly recommend Diaz Services for all of your AC needs!

• Called about loss of power to HVAC unit. I was told It needed Freon and was charged $500. A few days later, Same problem again. I called the company was told that someone was going to call me back, owner. Mr. Diaz. He has yet to reach out. I had somebody else come take a look. I was told that there was nothing wrong with the unit. The problem was a $20 Breaker that needed to be replaced. I feel completely taken advantage of and scammed.
