HVAC Service & Air Conditioning Repair in Herculaneum, MO
Heating and AC service for Herculaneum — the riverfront homes, the bluff subdivisions, and the Dunklin school district neighborhoods. 20 minutes from Hillsboro HQ.

Herc Homes and River Humidity
The Mississippi river bottom keeps Herculaneum more humid than the rest of Jefferson County. That shows up as condensate problems, sweating ductwork in crawlspaces, and evaporator coils that need more frequent cleaning. We design and tune systems with that humidity in mind.
Ricotta Heating & Air has worked on homes across Herculaneum, Jefferson 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 Herculaneum homeowners for over 50 years.
