Common Causes of Furnace Damage

Don’t be left out in the cold this winter. If you’re vigilant with your maintenance and repairs, your furnace should last through the cold season. Knowing how to care for your system is the first step in getting it to last. To prevent a premature HVAC replacement in Milton, GA, here are a few most common causes of furnace damage and how to prevent it from occurring.

Broken Thermostat

Did you know that your furnace thermometers and thermostat are two different things? These two components must be in constant sync in order for your furnace to function properly. If your thermometer breaks or needs to be recalibrated, it throws of your furnace’s ability to regulate temperature. It may turn on at irregular times or remain running far longer than needed.

Clogged Filters

When was the last time you changed your furnace’s filter? Depending on how often you run your system, it’s recommended that you change your filter every 3 to 6 weeks. Your filter creates a barrier that catches dirt, debris, and allergens before it enters into the ductwork of your home. If the filter hasn’t been changed in a while, it may be too dirty or clogged to prevent this sort of filtration. Not only does this lead to an excess of dust around your home, but it also causes your furnace to overexert itself.

Pilot Light Malfunction

Whether it’s automatic or manual, your pilot light is an integral part of your HVAC system. Without it, the fuel used by your furnace won’t ignite and no heat will be distributed throughout your home.  If your furnace is blowing cold air, check your pilot light to determine whether or not it’s been lit. Even if you suspect everything is in working order, it’s a good idea to inspect your pilot light at least once a year.

Broken Blower

The blower motor within your furnace is what blows the hot air through your ductwork, warming your home. Without it, there’s no regulating the temperature or circulating the heated air. Often times these motors fail from being overworked or due to clogs. Investing in yearly tune ups prevent these issues from occurring and keep that hot air flowing.

Fuel Line Supply

Your furnace is likely fueled by natural gas. There’s a supply line that feeds into your unit, ensuring that when the pilot light is lit and the furnace is engaged, there’s a steady and controlled flow of gas to heat and circulate the air. If the fuel supply has a problem, it could prevent your furnace from working properly. While you may suspect an issue, it’s always best to consult with a professional before attempting to repair any fuel line problems.
