"This guy is a real pro! The original installer came out and gave up on the problem, and I never heard from them again. Duke came out, and diagnosed the issue in an hour. He even submitted the request for a part under warranty, received it, and came back to install it 2 days later. The cost was very reasonable. Thanks Duke!"

"Overall good job and great customer service for all the folks that participated in the install and post installation questions. Nice work!!!! Karim."

"I had to have my 34 year old gas air conditioner replaced. I was very happy with the service I received . It was installed a few days later. I was very happy with the whole process. From Sam coming out to the installation. The guys were so nice and polite and professional. They cleaned everything up afterwards and Jesus was very patient with me setting it up and showing me how to use it. I am very happy with the whole experience. I would highly recommend them"

"Albert Nahman PHC installed new AC and Furnace for my house. I like them for several reasons -- 1. At first Tom explained in detail what equipment I need and how they work, and gave me a reasonable and detailed quote at end of the visit. 2. They offer interest free finance. 3. I got free upgrade for furnace when the original quoted is not available. 4. Their installer did good job, and cleaned up afterward. I highly recommend this company."
