A heat pump, PTAC or heating stage that won't come on.
Air that moves but never warms the room — often a refrigerant-cycle fault.
Zoning, airflow or equipment issues leaving parts of the space cold.
Heating that starts and stops every few minutes and never catches up.
Controls or reversing valves that won't make the seasonal switch.
Cold apartment, cold office — heating faults rarely fix themselves. Call and we'll get it sorted.
