HVAC Alarms: How to Remember to Change the Air Filter

HVAC Alarms: How to Remember to Change the Air FilterAs simple as it is, the air filter plays a big role in the efficient and durable functioning of your HVAC system. It safeguards the air handler from dust, which harms all things mechanical and electrical. If you want lower cooling bills and low maintenance costs, make checking the filter a priority.

Going High-Tech

Upgrade the thermostat. Programmable and Wi-Fi thermostats may have a feature that tracks the amount of time the HVAC system runs and turns a light on, sends you an alert, or beeps when it’s time to check it.

Install an air pressure sensor. Pressure sensors that fit between the air handler and the filter measure the air pressure. When it falls too low, it will send a signal to the monitor to let you know it’s time to change the filter. These are the most convenient, although not commonly used, devices if you want to keep your HVAC system running smoothly and efficiently.

Use your smartphone or computer. Use the calendar function to notify you when to check the filter.

Using Low-Tech Methods

  • Check the condition of the filter when you get your electricity bill. Since the amount of the bill is tied to the HVAC system, it makes sense to relate one to the other. Since HVAC system usage is seasonal, you won’t need to check it when your HVAC system hasn’t been used during months of little to no usage.
  • Write the filter check date on a wall calendar. Cross it off afterwards and note whether you changed it. The dust load in your home dictates how often it needs changing. Homes with pets, carpeting, or heavy fabrics tend to generate more airborne particulates the filter captures.

    If you want to reduce the level of dust and particulates, vacuum with a HEPA (high efficiency particulate air) filter instead of sweeping, and replace carpeting with hard surface floors.
