HVAC Service & Air Conditioning Repair in Eureka, MO
Heating and cooling service for Eureka, MO — from the older streets near downtown out to the newer builds off Six Flags Road and Allenton. Family-owned, with techs who'll tell you when a repair makes more sense than a replacement.

Eureka Homes Are Not One-Size-Fits-All
Eureka spans 100-year-old downtown homes with retrofitted ductwork, large 2000s subdivisions with two-zone systems, and newer construction with high-efficiency variable-speed equipment. Each calls for a different diagnostic playbook — the variable-speed boards in particular need a tech who knows how to read the fault codes instead of just swapping parts.
Ricotta Heating & Air has worked on homes across Eureka, 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.

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 Eureka homeowners for over 50 years.
