5 Reasons You Need to Change Your HVAC Filters Regularly
Wednesday, July 27, 2016
The HVAC experts suggest checking your filter at least once a month to determine whether it needs to be changed and actually changing the filter every three months. It is recommended, however, to change the filter more frequently (every month) during the hottest and coldest months of the year when the unit will be used more. This is acceptable for your standard fiberglass filters. Electrostatic or HEPA filters can typically last two to four months before requiring a change, though consider changing more often during the summer and winter.
Below are five important reasons to change your filters regularly:
1. Keeps cost down: A clogged air filter has to work harder, and therefore, uses more energy. More energy means more money on your electric bill.
2. Keeps the overall system clean: A clogged filter can pollute the entire HVAC system, which can cause some major issues, including costly repairs or premature replacement.
3. Extends the life of the HVAC unit: When dirt accumulates, air can’t pass through and the unit can overheat as it tries to keep up with the demand. This will lead to repair or even replacement of the unit, costing you money.
4. Helps the environment: Wasted energy will generate more pollution. More greenhouse gasses and carbon monoxide will be released if you use more energy--not to mention the impact it will have on your energy bill.
5. Healthy air quality: Accumulation of dirt and debris on your air filter can cause/worsen allergy or respiratory symptoms. If you have occupants with issues like asthma, allergies, or any other breathing issues, keeping the air free of pollutants is important. Plan to change the filter more often if you live with someone with any of these conditions, or if any of the following apply:
