When it comes time to turn on your heater, you expect the system to work reliably throughout the season. But, if your indoor air feels considerably warmer than it should, the problem could be due to several reasons that aren’t related to the heater. While it’s wise to have an HVAC contractor inspect the system, you should also consider these possibilities.

Why Your House Feels Cold

1. Clogged Filters

Air filters are designed to trap common household contaminants, such as dirt, mold spores, dust, pollen, pet dander, bacteria, and other allergens. Over time, this filter becomes clogged, preventing air from circulating freely. The heater then struggles to warm the home, which can ultimately lead to serious issues like frequent repairs or premature failure. HVAC contractors recommend replacing the filter at least every three months; you should do so more frequently if you have pets.

2. Air Leaks

Keeping the heater on doesn’t mean that it stays within the confines of your home. If there are even minuscule openings or gaps anywhere around doors, windows, crawlspaces, electrical outlets, or vents, then some of that heated air will escape. This puts the heater in the position of working harder to warm your home to your desired temperature. It also invites cool air inside, which can take away from your comfort as it gets colder outside. Sealing those gaps with materials like caulking and weatherstripping is essential to locking the heated air inside.

3. Blocked Vents

Heater vents should never be blocked by exterior materials, like furniture or rugs. While some homeowners may think this is an efficient way to reduce their energy costs and make select areas of the house feel warmer, it can backfire. The heater depends on proper air circulation to efficiently warm the home. When that balance is upset by blocked vents, the heating and air system may wear out quicker because it runs more frequently in its effort to warm the home. You may notice that it doesn’t work efficiently, that you need to have your HVAC contractor perform repairs more often, or that it stops blowing warm air entirely. Avoid this habit to protect the system.
