Heating and cooling systems rarely fail politely, and in San Marcos, TX, a breakdown usually arrives on the hottest afternoon or the coldest night of the year. The tricky part 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. That's the place to start if you need a fix today.
Warning Signs for HVAC Repair
Spotting the early warning signs lets you act before the problem gets expensive. These are the signals our technicians see most often:
- Water pooling around the indoor equipment, often from a clogged condensate drain
- Unfamiliar sounds from the equipment, like squealing, grinding, or banging
- The outdoor unit humming but refusing to actually start
- Vents blowing warm when you want cool, or cool when you want heat
- A breaker that trips whenever the system tries to run
- The system short-cycling on and off without reaching the set temperature
- Weak airflow from the supply registers throughout the house
- Rising utility costs even though the house feels worse
Don't Wait for a Total Failure
A failing capacitor, clogged condensate drain, or dirty flame sensor rarely fixes itself and usually gets more expensive to address the longer it runs. At the first hint of a problem, call (737) 344-9567 for a fast inspection.
