My HVAC system was not cooling down effectively. Omar and Jerald were very systematic in diagnosing the underlying issue and were able to quickly identify and fix it. They were professional and communicative throughout the process explaining in simple terms what was going on. Would highly recommend working with them!

I’m rather shocked at the highly rated reviews for their service. I have been nothing but disappointed in their service since we purchased our air conditioner from Costco. They have come out many times to patch a problem without finding the problem. This has been the past couple of years. They funky tool the time and dedication to locate the issue. This was back on Aug 11z then they kept pushing us off on fixing it. A couple of weeks ago, they came back out and said they needed a part. They have said part, but they have not come back, nor have they returned our calls to fix it. All this during one of our worst heatwaves. I spent a lot of money to add air conditioning to our 1908 home. It would be nice if it actually worked. I’m also surprised Costco whom I’ve always trustee in the past would work with a comp that had bad work ethics.

Precise Air is awesome. The office staff are friendly the technicians are knowledgeable and also friendly. I have been using them for our office building HVAC needs for quite sometime and they have never let me down. Communication is key with them, they keep me updated on part arrival, repair schedule changes, et al. I have always been happy with their services.

Omar was fantastic. He showed up exactly on time. He quickly diagnosed and offered me options that were very clearly communicated. He also did his best to make it as cost-effective as possible for me. He then performed the work in what I would consider record time. This type of A+++ service is rare these days. Thank you, Omar!

Omar was very efficient doing our summer maintenance. He clearly explained what he did. Not only did he demonstrate a knowledge of our system but he has a pleasant personality and we felt very comfortable with him.
