"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."

"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."

"Love the honesty, hard work and courteous demeanor of the Faszold employees. Jason Green was our tech today and he will be the one my husband and I request for every service. Was prompt, clean (wore shoe protectors in our home), professional and recommended ways to keep our system running efficient. Definitely was a great service call!!!!!"

Thank you to Jason Green and Dan Faszold for the checkup on my AC today. We have sold this home and are building another in St.Peters. We will definitely continue our great relationship with Faszold Heating and Cooling. See you in the Fall!"
