No heat
No heat can begin with the controls, airflow, defrost, electrical operation, or backup heat.
Heat pump service
A heat pump is a system, not a single appliance. OCD HVAC looks at how the equipment, airflow, controls, ductwork, and home affect one another before deciding what needs repair.

A heat pump is a system, not a single appliance.
Common heat pump calls
Heat-pump air often feels cooler than furnace air. Some systems also run for long periods by design. What matters is whether the system is delivering the heating or cooling the home needs.
No heat can begin with the controls, airflow, defrost, electrical operation, or backup heat.
A heat pump can heat correctly and still fail in cooling. Controls, airflow, electrical operation, and delivered performance narrow the cause. Refrigerant is only one possibility.
Light frost can be normal. Heavy ice points toward a problem with defrost, outdoor airflow, the fan, controls, or the refrigeration system.
Backup heat uses much more electricity. Controls, airflow, duct leakage, or weak heat-pump performance can make it run too often.
Diagnostic approach
The tests change with the symptom and outdoor conditions. The reasoning stays the same: confirm what is happening, understand the system, measure its performance, and let the evidence narrow the repair.
Repair or replacement
Will this repair restore dependable operation? Is it still a good investment? The answers depend on the failure, the system's condition, previous repairs, and whether it can still meet the home's needs.
The repair should correct the demonstrated failure, not merely make the system start once.
Cost is weighed against condition, past failures, remaining risks, and performance.
Repair or replacement should follow from measured operation, without pressure.
FAQ
A heat pump usually delivers cooler air than a gas furnace. The register can feel less hot while the home is still heating correctly.
Auxiliary heat automatically helps the heat pump. Emergency heat usually relies on backup heat alone. Too much backup-heat use can raise electric bills and signal another problem.
Light frost can be normal, and the system should defrost itself. Heavy ice or repeated freeze-ups point to a problem that needs diagnosis.
Long operation can be normal for a variable-capacity system. It can also point to weak performance, airflow or duct problems, incorrect controls, or excessive heat loss from the home.
