Des Peres' larger lots and finished basements need an HVAC company that knows how to size and zone — not just sell the biggest unit. Ricotta has been doing it the right way for 50+ years.
Des Peres Homes Need Proper Zoning
Most Des Peres homes have a finished basement, a main living level, and an upstairs that all want different temperatures at different times. A single-stage system can't deliver that — but a two-stage or modulating system with proper zoning can, often without replacing the ductwork.
Signs You Need AC Repair in Des Peres
- Vents blowing warm or room-temperature air
- Weak airflow even with the system running
- Short cycling (turns on and off rapidly)
- Energy bills climbing without a change in usage
- Rattling, hissing, or grinding noises
- Musty or burning odors when the AC runs
- Water pooling or ice forming around the unit
What We Check on an AC Service Call
- Refrigerant charge and leaks
- Capacitor and contactor
- Evaporator and condenser coils
- Condensate drain
- Filter and airflow
- Thermostat calibration
- Electrical connections
Most cooling failures trace back to one of these — we diagnose the real fault before quoting, so you're not paying for parts you don't need.

Des Peres HVAC Questions
How much does AC repair cost in Des Peres?
AC repair costs depend on the diagnosis, parts, and labor. Ask about diagnostic charges when scheduling; free estimates apply to system replacement.
How quickly can you provide AC repair in Des Peres?
Call during our 7 AM–8 PM hours to confirm the next available appointment in St. Louis County. Scheduling depends on demand and the repair needed.
My AC is blowing warm air — can you fix it?
Usually yes; warm air typically means low refrigerant, a failed capacitor, or a frozen coil — all things we carry parts for.
Should I repair or replace my AC?
Age, repair frequency and comfort all matter. We'll walk you through honest repair-vs-replace options; free estimates apply to system replacement.
How long does a furnace or AC last?
With annual maintenance, most furnaces last about 15–20 years. Skipping yearly tune-ups tends to shorten that and leads to more breakdowns.
What AC brands do you service in Des Peres?
All major AC and furnace brands, whether we installed the system or not.
