What customers said about a/c system repair
West Coast Air ConditioningIn two days, Elias and his crew took out My old furnace and installed a new furnace and air-conditioning with new ductwork all through the attic. It was amazing. It still is amazing. Elias went over and above because he didn’t leave my house till almost 6 o’clock in the evening making sure everything was working correctly. Very good work.
Pacific AireThe technician that Pacific Aire sent wasTyler Conroy . Excellent worker and respectful. His trouble shooting skills are very high. Good work Tyler.
TriCounty ServicesAlonzo, Armando, Marcos did a fantastic job installing my central air and new furnace. Oscar was great to work with helping me understand the system and how it all works. I'm super happy with my purchase, my house is comfortable again. I especially loved their speed at which they pick up the phone and call you back…
West Coast Air ConditioningThis review is for Tech #2. He quickly and efficiently diagnosed our Heat pump’s issue with cooling and offered an affordable and low cost solution to get us back up and running during an unrelenting heat wave. He clearly has a lot of experience and was very pleasant to deal with. Would request him in the future for…
Pacific Airegood experience, technician was completely informative and thorough. The only negative was the ridiculous "dispatch" fee.
Pacific AireHayden was very nice, polite and very knowledgeable. He explained things where it was very easy for me to understand. I highly recommend him.
