Frontenac homeowners get careful, respectful HVAC work from Ricotta — the kind of company that takes its shoes off and cleans up after itself. Family-owned for over 50 years.
Frontenac Homes Are Large and Layered
Multi-zone systems, finished basements, third-floor bonus rooms, and attached garages with bonus rooms above are typical in Frontenac. Comfort complaints almost always trace to zoning or return-air, not equipment capacity. We diagnose accordingly.
Signs You Need AC Repair in Frontenac
- 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

Frontenac HVAC Questions
How much does AC repair cost in Frontenac?
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 Frontenac?
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 Frontenac?
All major AC and furnace brands, whether we installed the system or not.
