When should I call an HVAC company for heating or cooling?

Call immediately for safety issues: burning smells, suspected gas or carbon monoxide, ice on equipment, or total loss of heat in winter. Call soon for warning signs: strange noises, weak airflow, short cycling, rising bills, or uneven rooms. Call seasonally for maintenance — spring for cooling, fall for heating.

Sooner Is Almost Always Cheaper

HVAC problems compound: a $30 filter ignored becomes a frozen coil; a weak capacitor becomes a dead compressor. The best time to call is when something first seems off — and the best insurance is a maintenance plan that catches issues before you notice them at all.
