When needing to replace your filter, these simple steps will help you measure the right dimension. Remember, regular maintenance of your home’s cooling and heating system is essential to ensure it operates efficiently. Proper maintenance will keep good air quality in your home, increase the life span of your system, and consume less energy – lowering your bills.
Your filters should be changed every 30 to 90 days depending on the type and efficiency of your filter. However, according to Energy Star (www.energystar.gov), filters should be changed every month during peak summer and winter months when your HVAC system is operating at highest capacity.
For safety, turn off your HVAC unit before attempting to change the filter. If you can’t figure out how to turn off the unit, turn off the breaker. Most air filters are located to the right or bottom of the unit and should easily pull out of the slot. Although not common, some filters are found in air vents instead. If that is the case, you might need to contact a professional for assistance.
To measure your filter, follow these easy steps:
- Step 1: Measuring Length and Width (L x W). (If your filter is not a square, the smallest measurement goes first).
- Step 2: Measure Depth (D) – Measure the thickness of your filter.
- Step 3: Put Your Measurements Together (L x W x D).
- It’s as simple as that!You are now ready to buy the right filter for your AC or Furnace
