Why Is My Heat Pump Running But Not Cooling Properly?
A heat pump can run without cooling if the filter is clogged, a power/control issue is present, or the system is making unusual noises that signal a fault. Appleton Campbell diagnoses and fixes these problems, and routine maintenance (inspections, cleaning, and adjustments) helps restore efficiency. Ask about our $49 Heat Pump Safety Inspection, and if your unit is aging, we offer free estimates for new systems across Ashburn and Warrenton.
Quick checks:
- Replace or clean the air filter.
- Confirm the thermostat is set to Cool.
- Note any new or unusual noises.
