When, Why, and How to Change Your Air Filter
HVAC systems are one of the greatest inventions of all time. They keep us warm in the winter and cool in the summer, and can also play a role in keeping contaminants out of the air inside your home. But just like any major appliance, your HVAC system needs to be regularly maintained to keep it in good working order.
While you should contact the HVAC professionals at Odyssey Mechanical at least once a year for regular maintenance, there’s one easy thing you can do yourself to help keep your HVAC system in tip-top shape: replacing your air filter.
Your air filter must be the correct size. Filters that are too large will not fit properly, and filters that are too small can allow particulates to bypass the filter, contaminate your air, and clog your HVAC system. And don’t forget that your home may contain multiple air filters. Be sure to check each one’s size and write them down for further reference!
Your new filter should have airflow arrows that indicate how it should be positioned inside the vents. Make sure the airflow arrows are pointing in, toward the HVAC system, and slide the new filter into place. Close the air vent, attach the grate, turn your system back on and you’re good to go!
Whether you need help determining which size air filter you need, or you have more serious HVAC issues that require expert attention, Odyssey Mechanical is here for you at 910-392-6400.
