Newberg Air Conditioning: DIY Maintenance Tips and Tricks for Your AC Keeping your air conditioning unit well-maintained will save you so much money on your electricity bill and cost on early replacement. Experts in HVAC services recommend having AC maintenance check and repair before the cooling season begins, and due attention must be given to your AC to ensure its full operational efficiency. The Heating, Ventilating, and Air-Conditioning or HVAC system is consisting ot either a furnace and AC or heat pump for cooling and heating, with interior components like evaporator and blower, and exterior components such as compressor and condenser coil. Allow us to give you some tips to maintain your AC applying to whole-home AC or heat pump unit. The dangers of working with an appliance electrical system and its moving parts poses great risk to safety, so you have to turn off your AC power completely and unplug it from the power source or outlet. You can find an exterior shut-off near the AC, and turn off the power at the breaker box indoors. 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. To clean the fins, use a strong stream from a garden hose and spray inside out to blast any dirt buildup between them, but avoid using pressure washer because it can damage the 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. Clean the area around the unit by raking the leaves and debris outside the unit condenser, cut branches and other forms of vegetation around on the outside condenser at least two feet in all directions, and when it is not in use during winter months, partially cover the top of the unit with plywood or plastic to prevent debris from falling into the unit. A condenser that is out-of-level can cause wear and eventual unit failure, so check the level and use rot-resistant shims to level it. In cleaning the evaporator coil, you may need to remove the foil duct tape and take out few bolts or screw, then use a soft brush to dust off the oil, and spray it with a commercially available no-rinse coil cleaner. It is also important to clean plugged evaporator using a wet/dry vacuum to clear any growing biological matter. Change the blower filter at least twice a year before the heating season begins.
