WHAT customers SAY

 Matt B. 

"A Jerry Kelly tech diagnosed our furnace as having a faulty gas control valve and gave us an estimate that we felt was too high. Jason Green from Fazold found the initial diagnosis to be incorrect and corrected the problem (as fused power cable that was toasted). He was thorough, professional and saved us ~$600 from what JK quoted originally. Well done and thanks!"

Tim M.

"Just had new Trane AC and Gas Furnace installed by Dave Henson and John Clark. What an efficient team! Arrived on time, very efficient and courteous employees. Great people made the install experience great. Kudos to them."

Jeff G.

"A job well done! Dave Henson and John Clark installed a new furnace and air conditioner for us today. They were incredibly professional and courteous, taking the time to fully explain what they had installed as well as how to operate the new system. Faszold continues to be my vendor of choice for heating and air conditioning needs!"
