Your heating, ventilation, and air conditioning (HVAC) system is an expensive and complicated piece of machinery, and you’re probably aware of how integral it is in the functioning and comfort of your home. Sure, it runs on its own, but without the proper maintenance, it could easily deteriorate over time. Taking just a few simple steps can help you keep your system running smoothly and avoid costly repairs.
Air filters are usually located in a couple locations within your house. They work to maintain your indoor air quality by removing allergens such as dirt, dust, and other debris. Neglecting to change out the filters regularly could lower the air quality in your home and cause the system to get clogged and possibly malfunction. It’s recommended that you change out your air filters monthly, though higher-quality filters will need changing less often, about every three months. Filters vary in size, so make sure you check the measurements before purchasing them.
Because your HVAC system is located outside the home, it’s susceptible to accumulating debris. Being located near or under a tree makes it more likely for dirt, leaves, sticks, and other debris to get stuck in the unit, so it’s best to keep it covered. Mowing the lawn or even a strong windstorm can get pieces of grass and dirt to get blown into the unit. If you notice that buildup has already occurred, take the time to clear it out. It may be advisable to call a professional as well, to check for any damage or clogs. A cover is also useful in the winter months to protect the unit from collecting snow or ice.
Your AC contains an indoor evaporator coil and exterior condenser coils, both of which can accumulate buildup over time. The indoor coils are somewhat protected by air filters, as previously mentioned, which prevent dirt from collecting, but over the years, a small amount can still get on them. This restricts the evaporator coil from absorbing heat and reduces airflow. The outdoor coil is exposed to even more debris, from dirt and foliage around your yard. To keep your system running smoothly, it is suggested that you clean your coils once a year.
Just like any other drains in your home, the drains in your AC system can get clogged with dirt and grime. Run something through the drains to remove buildup, since any type of blockage will prohibit the system from effectively reducing humidity and moisture. An excess of moisture can cause damage to the interior of your house as well as discoloration of your walls and carpet.
