4 Things That Might Happen If You Don’t Replace Your HVAC Filter


Air filter replacement is one of the pillars of HVAC maintenance. Most of the problems heating and cooling units develop can be prevented by simply keeping the filter clean. Normally, it needs attention once every three months, though thicker filters generally take longer to clog and may only need to be disposed of once a year.

Replace Your HVAC Filter

So what exactly happens if you don’t change your system’s air filter? Below are some of the problems that are likely to arise.

Inadequate Heating or Cooling

A dirty filter restricts the flow of air into the heating and cooling equipment. This can cause your furnace or air conditioner to suffocate, preventing it from producing enough conditioned air to reach the temperature set on the thermostat. As a result, your system will underperform, and you’ll eventually start to feel uncomfortable.

Short Cycling

This phenomenon happens when a heater or AC turns on and off repeatedly. When a unit short cycles, it may stop running before reaching the desired temperature for the room. Normally, you can fix this by changing the thermostat’s batteries, but if this fails then cleaning the air filter would be the next troubleshooting step.

Premature Equipment Failure

By neglecting a filthy filter, you can compromise the integrity of the entire heating and cooling system. Sooner or later, something will begin acting up, ultimately causing the equipment to break down.

Poor Indoor Air Quality

Filters purify air by filtering out and trapping pollutants as it flows through the interior heating and cooling components of the HVAC, while other electrostatic varieties attract dust particles. But no air filter has an unlimited capacity; the dirtier they get, the less effective they become as an air cleaning solution.
