Ellisville Homes and Bonus-Room Comfort
Ellisville's 1990s two-stories with bonus rooms over the garage almost universally complain about that bonus room being unusable in summer. The fix is usually a small zoning damper or a single-zone mini-split — not a bigger main AC.
Ricotta Heating & Air has worked on homes across Ellisville, 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 Ellisville 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 Ellisville homeowners for over 50 years.
