Heating and cooling systems rarely fail politely, and in St. Peters, MO, a breakdown usually arrives on the hottest afternoon or the coldest night of the year. What surprises most homeowners is how many different failures produce the same symptom. A system that runs but never reaches temperature might be fighting a weak run capacitor, a pitted contactor, a low refrigerant charge, a dirty flame sensor, or simply a filter so clogged the blower is starving for air. A system that will not start at all could be a tripped float switch on a backed-up condensate drain, a failed transformer, a bad thermostat, or a control board that has stopped sequencing the equipment.
Most of our service calls are for AC Repair and Furnace Repair. Start there if your system isn't running right.
When to Call for HVAC Repair in St. Peters
Spotting the early warning signs lets you act before the problem gets expensive. Watch for these telltale signs:
- Grinding, squealing, buzzing, or banging you have not heard before
- An outside unit that buzzes but will not start
- Rising utility costs even though the house feels worse
- Warm air from the vents in cooling mode, or cool air in heating mode
- Barely any air coming out of the vents
- Short cycling, where the system starts and stops without ever reaching the setpoint
- Puddles near the furnace or air handler from a blocked drain line
- Repeated breaker trips every time the heating or cooling kicks on
