Request heat pump serviceQuick checks before you call
- Check the thermostat: is it set to heat or cool, and is the set point where you expect?
- Check the filter: a clogged filter limits airflow. Replace it if it is visibly dirty.
- Check the power: look at the breaker and the equipment switch near the unit.
- Check the airflow: hold a hand at a supply register and feel whether air is moving.
- Check the outdoor unit: clear leaves and debris from around it.
Signs to call us about
Common heat pump problems
- Ice on the outdoor unit that does not melt. A thin layer of frost in winter is normal, and the heat pump melts it by itself. Thick ice that stays means the defrost is not working.
- Cool air in heating mode. The heat pump may be stuck in cooling, or it may be low on refrigerant.
- It heats but does not cool, or cools but does not heat. The part that switches between the two modes may have failed.
- It runs all the time. On a very cold day this is normal. On a mild day it is not.
- The electricity bill jumps in winter. The backup heat may be running too often, which uses much more electricity than the heat pump itself.
- It switches on and off every few minutes. The cause can be the thermostat, the airflow or the refrigerant charge.
When a heat pump stops heating in winter or cooling in summer, you need the real problem found, not a guess. SquareHVAC is based in Hillside and serves communities within approximately 30 road miles. We diagnose and repair heat pumps for homes and businesses across the Chicago suburbs.
What heat pump service covers
Maintenance
One bookable visit a year, ideally before the season the system struggles in: coil cleaning, airflow checks, electrical connection inspection and thermostat calibration.
Replacement

We aim to arrive within 2 hours from the time you call, depending on the distance to your location and current availability. Emergency service is available 24/7, including Sundays. Non-emergency visits outside routine service hours are scheduled for the next working period.
What the cost depends on
The cost depends on the failed component, parts availability, system access and labor. Our guide on what HVAC repair costs and what drives the price explains the factors.
The written quote
We explain what we found and what it costs, in writing, with parts and labor listed separately. You review it; you decide. Work only begins once you approve.
