WHAT Customers SAY

 Jeff C. 

"I just wanted to say Thank You. Your company blew me and my wife away with your prompt and courteous service. The 2 Techs that come to my home to do the AC install were fantastic. Everything was explained to me and they made sure I didn't have any other questions before they started the install. You have a top notch company and I will tell everyone that I know that they need to call you for all of their heating and cooling needs. Thank you again for making what could have been a very stressful ordeal into one of the most easiest and smoothest home repairs."

Ron B.

"I had a new Trane Air Conditioner and Furnace installed in April and was very pleased with the installation and the Air Conditioner performed outstanding in the hot summer months. I was also pleased with the lower electric bill compared to previous years. Today your technicians came and did the fall checkup so I am ready for winter. They were very friendly and did and outstanding job. Thank you for all your help and I will recommend Fazsold to everyone who is looking for a new Air Conditioner or Furnace."

"WOW! What a great team! We were in the market to replace our old AC unit & furnace and called Faszold. We contacted 2 other well known companies which were very high. John & Dave came out that week and installed the units. They were hard-working, friendly and very knowledgeable as well and went over everything after installed and answered my questions. The customer service that we received from them was just outstanding and I feel that this company is very trustworthy. I would definitely refer them to friends & family."
