When Should I Change My Air Conditioner Air Filter? Published on February 26, 2015 Occassionally we’re asked what is the best thing that Ogden area homeowner's can do to protect their air conditioning and heating system between their scheduled PLUS Maintenance Tune-ups? Our advice is simple; remember to change the heating and air conditioning air filter. Buying new furnace and return air filters is crucial to the ideal operation of your HVAC system, as well as your home's air quality. Research suggests that indoor air pollution is in the top five environmental health risks? We know it's the last thing on your mind, but this is really important stuff. Changing the air filters is not all that hard for most Ogden homeowners, but there are often two challenges to actually completing this job: Determining just how often to replace your furnace or air conditioner filter. Remembering to change air filters when needed. When To Change Your Air Filters Most filters have a timeline printed on the packaging. It may instruct "Lasts up to 3 months" or "Change filter every 90 days". Pay attention at the store and you'll notice that some are designed to only last a single month, while other manufacturers (like Honeywell) have released media air cleaners with filters meant to be changed once every 6-12 months. The norm seems to be once every three months for most higher quality filters, but we have a rule of thumb that we recommend our customers to go by. If the filter is dirty, change it! A dirty air filter can contribute or cause damage to costly equipment, like your compressor, so it's recommended to change it out more often than neglect it. If you want to stick to the manufacturer's recommended limit, we suggest scribbling the date on the filter when you swap it out, and adding a reminder for yourself in your phone or on a calendar. Also note that your filter manufacturer sometimes has a different recommendation from your HVAC unit manufacturer. Deciding how often to change your air filters can depend on several factors: The type of air filter you are using The collective air quality of your Ogden area home Pets – Dogs, cats, etc. Occupancy of the home General air pollution in the Ogden area or construction taking place nearby For the common 1"-3" air filters, the manufacturer specs basically suggest to change them every 1 or 2 months, which is in fact a great rule of thumb. Still, general guidelines are not applicable to all. If you have to endure light to moderate allergies, you might require an upgraded air filter or change them even more frequently than OEM specifications. On the other hand, if you're in a remote area, own a infrequently occupied home (like a vacation home) or an area with few automobiles and trucks, annual replacement of your air filter may be quite sufficient. Why do pets matter so much? They have a tendency to shed, which can clog your air filter fast. Clearly, the air filter is just doing its job by trapping pet hair and dander, but tremendously dirty filters can cause seriously reduced HVAC performance. In summary: Seldom used home or single occupant homes without pets or allergies: Change 6-12 months Common suburban home without pets: Change every 90 days Got a cat or dog: Change every 60 days More than one pet or have allergies: Change every 30-45 days How To Remember To Change Air Filters It's simple; sign up for the Service Experts Email Club.

How to replace your return air filter Most of you know how to replace the air filter in their unit, but some homes have an extra filter in the return vent. Whether you have one or not is dependent on the HVAC manufacturer's recommendation. Your HVAC is engineered to handle a maximum amount of pressure in your house, and the more filters you have the fiercer the blower motor works, which can reduce the lifespan of your system if it isn't designed for it. Discovering whether you have a return filter and replacing it is simple: Go to your return air vents. Some covers have screws and some have tabs. Unscrew or pull tabs to take off the wall. Look for a filter. If one is there, pull it out and record the size. Verify the filter type is the one recommended by the manufacturer. If filter is dirty, replace with the manufacturer's recommended filter of the same size and type. Crazy as it may seem, filters can greatly alter your home's airflow, which is why we recommend referring to the manufacturer. A higher quality HEPA filter that is designed to catch tinier particles will reduce airflow more than a cheaper filter. With restricted airflow comes greater pressure on your system, so you need to verify that your HVAC system was engineered to handle it. Otherwise, you may experience reduced heating and cooling efficiency in your home, and system parts may break down much faster than the standard.
