Newberg Air Conditioning: DIY Maintenance Tips for Your AC You can extend the lifespan of your air conditioning unit by having a regular maintenance and you’ll get to save money on your energy bill as well as on the cost of early replacement. According to HVAC experts, an AC requires regular attention to make sure that it is operating at its maximum efficiency and to prevent wear over time. A home’s HVAC system (Heating, Ventilating, and Air-Conditioning) consists of either a furnace and AC or heat pump, which both cools and heats, and both have interior evaporator and blower, and exterior compressor and condenser coil. Allow us to give you some tips to maintain your AC applying to whole-home AC or heat pump unit. Because of the danger of working around AC moving parts and electricity, it is important to turn off the ACpower completely. On the exterior compressor or condenser, find the exterior shut-off box adjacent to the unit, and turn off the power indoors at the breaker box. With the use of a wrench or screwdriver, you can remove the fasteners and lift the fan grill or cage away from the top of the unit, then wet or dry vacuum to clean the dust and dirt from the unit’s interior. When cleaning the fins, avoid using pressure washer as it can damage the fins, use a strong stream from a garden hose and spray inside out to blast any buildup of dirt and debris, and you can also use a commercially available fin cleaning spray to clean very dirty fins. Any reduction in your units air-flow reduces efficiency, so it is important to straighten bent fins using a commercially available fin straightening tool or butter knife to gently straighten bent fins. Replace the fan cage once you are done cleaning, rake back debris and leaves outside the condenser and cut any branch, grass or vegetation at least two feet in all directions to ensure unobstructed airflow around the unit. Over time, soil can settle on the pad upon which the condenser unit sits, so it is essential inspecting and leveling the unit by using rot-resistant shims. When cleaning the evaporator coil, you may have to take out few screws and bolts, and remove foil duct tape, use a soft brush to dust the coils, spray a commercially available no-rinse coil cleaner, draining the drip into the pan, and clean the pan with soap, hot water, and bleach. You also need to clean any plugged evaporator drain using a wet or dry vacuum. Change the blower filter at least twice a year before the heating season begins.
