How Your Air Filter Affects Your Heating and Cooling

Changing air filter to improve indoor air quality (IAQ)

Your HVAC air filter in your Savannah, GA home is a small, but significant feature of your system. It traps dust and dirt from circulating through your home and prevents poor IAQ. Although the air filter benefits your home, it can create problems if you don’t clean or change it regularly. Check out a few of them below.

Clogged Air Filter Causes Uneven Heating and Cooling

When your air filter is clogged, it’s difficult for air to pass through the filter and into your home. You’ll likely feel cold or hot spots throughout your home depending on the season when adequate air can’t get through the filter efficiently. If you’ve changed the air filter and are still noticing uneven heating and cooling, then you may want to consider adding insulation to your home, as insufficient insulation is another perpetrator of uneven heating and cooling throughout the house.

Higher Utility Bills

When your furnace or air conditioner has to work harder to heat or cool your home, it’s going to translate to higher utility bills. The harder your system works, the more gas or electricity it pulls to do its job. Making your HVAC system work harder will show up on your monthly utility bills. By keeping your air filter clean, you use less energy to heat or cool your home. Since your HVAC system is one of the biggest energy consumers in your house, you want to do all you can to keep those costs down.

Increased Dust

A dirty air filter leads to increased dust in your home. If your filter is clogged, then that air is pushing through that dirt to get into your home. Typically, just the smallest particles will make it through meaning you’re going to see more dust show up in your home. Although you should clean dust with a wet rag to prevent it from continually circulating, you also want to keep your air filter clean, so it doesn’t have the opportunity to accumulate in the first place.

Lowered HVAC Lifespan

The better you take care of your HVAC system, the longer its lifespan. Without regular maintenance and upkeep, like changing the air filter, it simply won’t last as long. Equate changing the air filter and routine maintenance to the oil changes in your car. You know your car runs better and lasts longer when you have the oil changed, so it’s important to apply that same concept to your HVAC system. During the high seasons, check the air filter monthly and clean or replace it when you see it getting dirty or clogged.

Poor Indoor Air Quality

When your filter starts to get dirty, all the air that comes into your house must pass through that dirt and debris. Your air filter exists in part to prevent poor IAQ in your home. It can’t do its job effectively if it’s clogged up. Your HVAC system will work harder to blow air into your home which will likely bring in more bacteria, dirt, and dust. You don’t want you and your family to breathe in all of that. Poor IAQ is damaging to your health causing headaches, cold and flu-like symptoms, inflamed allergies, and asthma triggers. Not changing your filters is one of the biggest causes of poor IAQ in your home. Change your filter regularly and also consider getting your IAQ tested and work to make sure it doesn’t become an issue in your home.

Decreased HVAC Efficiency

Decreased efficiency will raise your utility bills and wear down your unit faster. There are also other concerns with reducing your HVAC efficiency. An inefficient system will leave hot and cold spots throughout your home. It will also take longer to heat or cool your home, and you might notice the temperature varying significantly from your thermostat setting. When it takes longer to heat or cool your home, you’re more likely to crank up the thermostat in hopes of speeding up the process. This lack of efficiency can translate into big spikes in your utility bills. If you need HVAC maintenance or help with your filter, we are the people to call.
