Routine inspection of your unit by air conditioner service technicians is extremely important to ensure you’re A/C units’ efficiency. However, properly caring for you’re A/C in between visits can also help you maintain the most cost and energy-efficient unit possible. The most important maintenance task that will ensure the efficiency of your air conditioner is to routinely replace its filters. When you don’t replace your air filter, the filter media loads with dirt and gets clogged, which reduces airflow, increases air conditioning and furnace run times(reducing a system’s efficiency significantly) Which causes unnecessary wear on components (which can result in expensive repairs). If you notice that heating and cooling your home takes longer than normal or that certain rooms further away from your AC and furnace aren’t warming or cooling, your air filter may be dirty. Also, air that bypasses the filter may carry dirt and contaminates directly into your A/C system and into the air in your home. When air conditioning and furnace run times increase, so does your utility bill. According to the U.S. Department of Energy, changing air filters can save homeowners up to 15 percent on their utility bill. Considering the DOE also estimates 48 percent of energy costs come from running air conditioning equipment, air filters not only provide energy savings but also cost savings. Changing your units filter when needed is a simple and inexpensive way to help maintain your systems efficiency and longevity.
