How Often Should I Change My Air Filter?

Air filters are used to keep the air in your home or office clean and to keep your furnace or air handler equipment clean. Dust and dirt from the air can clog your air filter and cause your AC or Heat Pump system to work extra hard to circulate air through your home. This extra effort can cause serious problems to your HVAC system.

As a filter gets clogged with dust and debris it becomes more difficult to draw air into the AC or Heat Pump system (think about breathing through a straw). This means your air conditioner has to work extra hard to compensate for the reduction in air flow. This may also lead to subpar cooling as the temperature in your home becomes inconsistent or inadequate. One of the greatest concerns of a dirty air filter is that it may cause the air you breathe to be unhealthy.

Another serious consequence for not keeping a consistent maintenance routine and changing your air filters is costly repairs and/or a shortened lifespan for your AC system. Repeatedly running an AC system with a dirty air filter can cause costly damage to your system.

Please remember to change your air filters every month during the Texas heat when your system is running constantly, and every 2-3 months during the fall and winter, or according to your manufacturers’ recommendations.
