If your home is feeling chilly during the fall and winter seasons, it could be time for professional furnace repair. There may be clear signs that your furnace is struggling to keep up already, which could save you from a furnace malfunction at the most inconvenient time. Common signs of furnace problems should not be ignored if you want to avoid surprises with your HVAC system. This blog will share common signs of furnace problems and ones that indicate that the system needs to be repaired.
One of the biggest signs of furnace problems is the changing of the pilot light. When your furnace is working correctly, the light will be a bright blue color, but yellow can indicate a gas leak or other problem. Carbon monoxide can leak from a damaged furnace, which is a highly poisonous gas that needs to be handled by a professional immediately. If you notice a change in your pilot light, contact an HVAC professional to check your carbon monoxide levels or replace your furnace.
When a furnace is overworked or has to run consistently to keep your home at a consistent temperature, your monthly energy bills will increase. If your monthly bills have risen, it can be a sign that your furnace needs to be repaired or replaced. Professional services will help find the root cause of an overworked furnace that causes higher energy usage. Annual tune-ups will help prevent furnace problems that can affect your energy bills.
Odd noises from a furnace or other HVAC element are an indicator of furnace deterioration. Popping, clanking, or squeaking are some of the odd noises you may hear while the furnace is running or just starting up. These often indicate that a piece is loose or that parts are worn out. Having the system checked by a professional will help tighten all bolts and parts, or check if the sounds are due to a faulty system.

When your furnace senses that the house is too cold, it turns on to raise the temperature set by the thermostat. When your furnace is constantly cycling (turning on again right after turning off), this can indicate a malfunctioning furnace. When the furnace can’t keep up with the set temperature, it could be do to plugged filters, failed heat exchangers, or a restricted exhaust system. It can be hard to diagnose the problem with a furnace on your own, so you should work with an HVAC professional to ensure you don’t cause damage or injury when tinkering with the furnace.
If your home takes forever to heat up or doesn’t stay warm after the furnace has been running, you should have the furnace inspected by a professional. Especially during cold winter days, the longer the furnace takes to heat the home, the less time you want to spend in your home. If your home feels too cold even after cranking your thermostat, call your local HVAC expert to see if there is a larger problem that requires furnace repair.
Burnt odors from your vents or furnace are not normal and can indicate melting components inside the furnace or duct system. The safety features inside your furnace may have failed or have problems as well if you are noticing strong odors when the furnace is running. Exhaust, blower motor, and the furnace control panel may not have detected electrical burning or melting, which should make the furnace inoperational. If you notice these smells, turn off the furnace immediately and schedule a service.
