Honest AC Repair Across St. Louis & Jefferson County

Most AC failures come down to a handful of issues — a failed capacitor, low refrigerant from a slow leak, a worn contactor, a clogged drain, a tired blower motor, or a thermostat that's lost its mind. Ricotta diagnoses what's actually wrong before quoting parts, so you're not paying for guesses.

If your system is older and the repair bill is creeping up, we'll lay out the math on repair vs. replace honestly. No scare tactics, no pressure — just the real picture so you can decide.

TL;DR
  • Same-day diagnostics on most calls
  • Repairs across all major AC brands
  • Clear options — repair, replace, or wait
  • No high-pressure upsells
  • Local family-owned, 50+ years
