What customers said about HVAC system repair
Pacific AireHayden was AWESOME. The epitome of great customer service with extensive knowledge. I wish he worked with every company Zi deal with!
West Coast Air Conditioning5/5 Stars ⭐⭐⭐⭐⭐ They gave us an appointment window of 8:30–10:00 AM, and the technician arrived right on time, which I highly appreciated! Joby (Technician #2) greeted me with such a sunny attitude that it completely set a positive mood for the day. He worked incredibly fast and didn't mind my three dogs barking…
Kaiser Air Conditioning - HVAC in…Lost AC during the hottest day of the year. They were able to get someone out the following day to repair my system. Roberto was very helpful spent a lot of time diagnosing and explained exactly what needed to be done and the cost related to the repair before he started work. I have been a customer for over 18…
TriCounty ServicesI unfortunately have to change the review since now TCS implemented an AI call filter callback system. I am not a fan of having to wait by the phone for a call back to connect with a live human.
Pacific AireRUVUN and BOB were very helpful and very professional. José and Vincent were tremendous today in putting in our new furnace. You guys have been very good as Pacific Aire for the Anglin family.
Pacific AireAs usual your technician was on time and diagnosed my problem and facilitated getting it corrected. I know it will take a few days as parts need to ordered but knowing it is well on the way to being fixed. Thank you for always hiring the best technicians.
