HVAC Service & Air Conditioning Repair in Arnold, MO
Ricotta Heating & Air is on Arnold streets multiple times a week — from the Telegraph Road corridor up through Richardson and out toward Tenbrook. Local family-owned since 1974, with techs who know which subdivision uses which brand of furnace.

Arnold Homes and Their Quirks
Arnold's older ranches off Jeffco Boulevard often still have the original 1970s gas furnace bolted onto undersized return-air ductwork — they cool fine in May, and overload by August. The newer two-story subdivisions south of 141 typically have a high-efficiency furnace in a tight upstairs closet, which means condensate pump failures are the #1 no-heat call we get from those streets.
Ricotta Heating & Air has worked on homes across Arnold, 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.
Why Arnold 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 Arnold homeowners for over 50 years.
