What can cause this HVAC problem?
Check that the thermostat is set to Heat and the filter is not clogged. Keep the outdoor unit clear of loose leaves and other obstructions, but do not chip ice from the coil or pour hot water on it. Some frost and defrost cycles can be normal; heavy ice that persists or a system that never warms the home deserves attention.
Safe checks homeowners can make
A qualified technician can determine whether the issue involves controls, airflow, refrigerant, a reversing valve, or another component. Arrange heat pump repair if performance remains poor. If the system is also failing to cool, the AC repair page may help you describe the symptoms.
When to arrange professional service
For an older system with recurring problems, compare repair with HVAC replacement or HVAC installation. Proper HVAC maintenance can check operating performance. If your property uses ductless equipment, see ductless mini-split service and the [homepage](/).
What to ask before approving a repair
Ask the service provider to explain the diagnosis, the work being recommended, the estimate, and any applicable warranty. Share the equipment type and symptoms you observed. Do not attempt electrical, gas, or refrigerant work yourself. Service availability and the work offered should be confirmed directly with the provider.
