I am a Realtor and see a lot of different contractors. Desert Star is EXCELLENT. I used them on another property yesterday. The seller's HVAC contractor told me the HVAC was fine on a house my client was buying. I had a feeling that it wasn't working because the heat took forever coming out. I called Fernan with Desert Star for help ASAP. He came out and confirmed that the unit was not working. He did a couple of fixes and the unit worked perfect!!!! The buyer was so happy!

Satisfied Customers

My daughter had recently purchased a new air conditioner from Desert Star and was very pleased with the service, however when my air conditioner went out I could not remember this and had a well known company come out try to sell me a 12k unit, I told them I would have to talk to my daughter and son in law and would let them know, my daughter called Desert Star and fortunately had someone not to far away and was able to stop by to take a look, they told me the system was old and wouldn't be a bad idea replacing it, however they could get it up and running for $164.32 and left a quote for a new AC that was half the price of the other company. Im very pleased with the service, the office staff and the gentleman that came out to get me back with cold air. Would highly recommend them! Thank you!

I will be using Desert Star for all my AC/Heating needs from now on. The whole staff I came in contact with was friendly and very polite. The office and technician working on my unit kept me up to date on the repairs needed. Also the price of the repairs were reasonable. I highly recommend using them. Thank you Desert Star!
