It’s that time of year again when the cold air has arrived and many residents are beginning to switch over to heating their homes. Like any other appliance, your heating system can have issues, especially when turning it back on after months of sitting idle. Here are some common furnace issues and how to fix them so your home stays warm and comfortable all season long.

Dirty Filters

Filters are a vital piece to your home’s HVAC system and should be changed every 30 days depending on use. Homes with pets may require changes more often. Dirty or clogged air filters can restrict airflow and force your furnace to work harder. Not only will this lead to less heat coming out, but it can also cause your heat exchanger to overheat and shut off your furnace.

Thermostat Issues

A faulty thermostat is a common issue with an easy fix so it’s always a good idea to have this assessed when you’re having problems with the heat. First, take a look at the settings on the thermostat. Next, check or replace the batteries. If temperatures still do not seem to match up, there could also be a problem with the wiring that connects to the unit.

Faulty Pilot Light

The pilot light is a small flame that ignites the furnace to distribute heat throughout your home. Thermocouple problems, drafts or clogs in the appliance may cause the pilot to have trouble lighting. If you think you’re having issues with the pilot light, contact a professional to help you relight it.

Noisy Furnace

A squealing furnace can indicate a slipped or worn blower belt. The belt will either need to be tightened or replaced if it looks damaged. If your furnace is producing a grinding or scraping noise, it means your ball bearings have worn out. A rattling noise can be a warning sign that the heat exchanger could be cracked, sending dangerous toxins into your home. If you hear any of these sounds, it’s best to turn off the system and wait for a technician to assess the problem.
