HVAC technicians recommend yearly service for furnaces to make them last as long as possible. Most furnaces last between 15 and 20 years when well maintained, but that doesn’t mean they don’t need repair now and then. If your furnace experiences any of these warning signs, it’s time to call an HVAC technician.

5 Signs Your HVAC System Needs Repair

1. Your Thermostat Doesn’t Work Properly

Thermostats are built into furnace systems to control the amount of heat that is pushed through your air ducts. When a thermostat malfunctions, you could experience colder-than-expected rooms. If you keep adjusting your central thermostat to heat all the rooms in your home, it should be checked by an HVAC technician.

2. You Find Water Pooled Around Your Furnace

If your HVAC system stops heating as efficiently as it usually does, examine the furnace for tell-tale signs of a problem. One visible sign of a problem is excess water leaking from your unit. This happens when a condensation line or drain becomes clogged. 

3. It Only Blows Cold Air

A thermocouple is a safety device that turns gas off when the pilot light goes out. If your furnace suddenly starts blowing cold air, there’s a problem with the thermocouple or pilot light that needs to be addressed by an HVAC technician. 

4. There’s Poor Air Circulation

If it takes a long time for your home to reach your desired temperature or if there’s no temperature consistency between rooms, there could be numerous causes, including malfunctioning fan motors, loose belts, dirty air ducts, and faulty bearings. A technician will examine your unit to determine the cause and recommend a solution.

5. You Hear Strange Noises

It’s not normal to hear clanking, bumping, or squeaking when you turn your furnace on. The cause could be anything from worn fan bearings to a frayed blower belt. The noises indicate your furnace needs servicing sooner rather than later.
