Central Air Systems Maintenance

Having the most energy-efficient system ever built won't matter much if it's not maintained. Lack of maintenance is the number one problem causes of central air conditioner systems. Before each cooling season, it's recommended that your system get a professional tune-up. However, there are things you can do in the meantime to make sure your North Las Vegas central air conditioner system runs efficiently throughout the year.

• Replacing the filter in any central air conditioner systems is a must. Learn your manufacturer's instructions for cleaning or replacing your filters. Never run the system without the filters in place, and always let a washed filter dry completely before reinstalling it. Once a month clear any leaves or debris from outdoor condensers. This is especially crucial during the summer months. Clean the condenser fan blades before the start of the cooling season. Brush any dust or debris off gently and then uncover the condenser coils, gently cleaning the dirty side. Then wrap the motor and other electrical components in plastic bags and gently spray from the inside with a hose. Also, check the base pan under the unit and clear it out of any debris that has gathered.

• Inspect your central air conditioner fan blades every maintenance period. If your fan has been making a clicking noise that means it's been striking something. If your blade has bent, don't try to straighten it. It could have become unbalanced and will only cause more problems down the line. Replace the blade. Maintain a 2 foot clearance around your unit. Don't let any plant or vegetation grow near it as it could obstruct the HVAC's ability to "breathe". If you have a lawn near the unit, make sure any grass cuttings fly away from it. During autumn seasons, be sure to keep leaves away from the fan grill to avoid blockage. Lubricate the condenser fan motor. If there are oil ports, they will be covered with rubber or metal caps. 10 drops of SAE 20 oil per port is sufficient. Shade the compressor unit if possible, have some kind of shading over it to keep the air temperature around it 5 to 6 degrees cooler than the unshaded air. 

• Have a form-fitting cover during the winter months. Do not run the unit when it's colder than 60 degrees outside. Clean the indoor evaporator coil and remove the front panel of your heating unit by using a soft brush attachment on a vacuum cleaner gently clean any dust off of the coil. Inspect the fins, making sure they're straight. If any are bent, a fin comb can be bought at any refrigeration supply dealer. Clean the drain pipe and evaporator trap: Flush the trap with water and then disinfect with one tablespoon of bleach.

Clean registers, baseboard heaters and radiators as needed. Be sure to move furniture, carpeting or drapes so they are not blocking the registers, heaters or radiators.
