When a furnace stops heating or an HVAC system starts acting up, it can be hard to know what is a quick fix and what needs a technician.
First, confirm the thermostat is set correctly and replace the air filter if it is dirty. Early diagnostics can prevent bigger damage in parts like igniters, blower motors, capacitors, and safety switches. Depending on what is found, the solution may involve furnace diagnostics and repair, thermostat repair and replacement, air handler and blower repair, or HVAC tune-up and maintenance to restore normal operation. Seasonal tune-ups, filter changes, and basic checks help systems run more efficiently and can catch small problems before they become major repairs
