Heat Pump Running Constantly
Here's what typically causes this, and why an on-site diagnostic — not a phone guess — is what gets you an accurate estimate.
Refrigerant Charge Low
System struggles to reach setpoint.
Thermostat Miscalibration
Reading doesn't match actual temperature.
System Undersized or Aging
Reduced capacity relative to the space's demand.
Why diagnosis matters: A symptom like this can trace back to several different root causes, and the fix — and its cost — depends entirely on which one it is. Roxly doesn't quote a repair price over the phone based on a symptom alone: a technician inspects the equipment on site, tests the likely components, and confirms the actual cause before giving you a firm estimate. That's what makes the quote accurate instead of a guess you find out is wrong after the work starts.
Is running constantly the same as short cycling?
No — short cycling is frequent on/off; this is the system running for extended periods without reaching setpoint.
Does this always mean a repair is needed?
Often yes, though in extreme weather some extended run time is normal — a diagnostic visit tells you which.
