HVAC, Sheet Metal Fabrication
"My furnace hard failed Monday nite, I called STI and they contacted me to schedule a service tech (Ted) who came by 1st thing Tues Mrng. He was professional, explained every possible cause of failure and resolved my issue. The cost to repair was very reasonable (not cheap), but fair for considering the 2 major components that failed. My house is hold again! I will use STI Heating moving forward!"
