HVAC Service & Air Conditioning Repair in Frontenac, MO
Frontenac homeowners get careful, respectful HVAC work from Ricotta — the kind of company that takes its shoes off and cleans up after itself. Family-owned since 1974.

Frontenac Homes Are Large and Layered
Multi-zone systems, finished basements, third-floor bonus rooms, and attached garages with bonus rooms above are typical in Frontenac. Comfort complaints almost always trace to zoning or return-air, not equipment capacity. We diagnose accordingly.
Ricotta Heating & Air has worked on homes across Frontenac, 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.
