Heating and cooling systems rarely fail politely, and in Denver, CO, a breakdown tends to land 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 nothing more exotic than 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.
Our two most requested repairs are AC Repair and Furnace Repair. If something has stopped working, start there.

Recognizing the warning signs early can save you time and money. Watch for these telltale signs:
- Utility bills climbing while comfort keeps falling
- Vents blowing warm when you want cool, or cool when you want heat
- Unfamiliar sounds from the equipment, like squealing, grinding, or banging
- Water around the indoor unit from a clogged condensate drain
- Airflow at the registers that feels weak in every room
- Repeated breaker trips every time the heating or cooling kicks on
- The outdoor unit humming but refusing to actually start
- Short cycling, where the system starts and stops without ever reaching the setpoint

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 (970) 602-4899 for a fast inspection.
