What Fenton Homes Need From an HVAC Tech

Fenton's a real mix: 1990s–2000s two-stories in the Bluffs subdivisions with 80% furnaces hitting replacement age, ranches off Old Gravois Road on slab with single-zone equipment that struggles upstairs in finished attics, and newer builds south of Highway 30 already on variable-speed heat pumps. We size and tune each one differently — bigger isn't better here.

Ricotta Heating & Air has worked on homes across Fenton, St. Louis County for decades — diagnosing failed compressors, replacing aging R-410A systems, swapping smart thermostats, and sealing leaky ductwork. From quick repairs to full system replacements, we explain what's actually wrong, give you fair options, and never push equipment you don't need.

Why Fenton Homeowners Trust Ricotta for Furnace Repair

When your furnace quits during a Missouri cold snap, you want a local technician who picks up the phone, shows up on time, and gives you a clear answer — not an upsell. That's been our promise to Fenton homeowners for over 50 years.
