01
What changed?
Note whether the system is completely off, blowing cool air, cycling, making a new sound, or heating some rooms differently from others.
Heating repair
No heat needs a diagnosis, not a guess.
United checks the equipment, thermostat, controls, and airflow, then explains whether repair still makes sense.
02
Check the controls and airflow
The thermostat, zone setup, and ductwork can change how a heating problem looks. They belong in the diagnosis when the symptom points there.
03
Age is not the diagnosis
The actual fault and condition of the equipment determine whether repair still makes sense.
