"Joe was fantastic! He was friendly and knowledgeable! He fixed the issue with my furnace when another company could not. He explained everything along the way. He caught an issue that will buy me some extra life on my aging furnace. Fair pricing. Highly recommend!"
- Bernadette C.
"Joe was very professional, courteous, and was able to fix my furnace quickly, at a reasonable price. Meanwhile, other companies said they couldn't repair it, and it needed to be replaced. Joe gave my furnace extra life, saving me thousands. I couldn’t be more grateful!"
- Pat C.
"Joe is honest, reliable and reasonably priced. I recently relocated back to the area and he addressed furnace issues in my newly purchased home and installed a new air conditioning unit. The homes unit was older than Jesus’ sandals. I am thoroughly satisfied."
- Susan L.

Not All Techs Are Created Equal
Service Tech Heating & Air Conditioning sets itself apart by employing only NATE-certified technicians, a distinction that not all HVAC companies can claim. NATE, which stands for "North American Technician Excellence" is the industry’s leading certification program, ensuring that technicians have the skills and knowledge needed to handle today’s increasingly advanced heating and cooling systems. To achieve NATE certification, technicians must pass a rigorous, nationally recognized test that is developed and supported by experts from every corner of the HVAC industry. NATE-certified technicians are preferred by contractors because they have a proven record of performing jobs right the first time, remaining in the industry longer, and delivering higher productivity compared to non-certified counterparts. At Service Tech, customers can trust that each technician is dedicated to the highest standard of service and expertise.
