Home Page >> Service Plans >> Benefits of Proper Maintenance Clean Condenser Coils Dirty condenser coils will raise refrigerant pressure higher than needed, increasing your electric bill. Cleaning the coils will keep your equipment at maximum efficiency while at the same time, saving you money. Check the Refrigerant Charge The refrigerant charge is checked by measuring temperature differential and determining electrical demand on the compressor or by reading the pressure gauges. A low or high refrigerant charge can easily go unnoticed and increase operating costs. An improper charge can also cause compressor shut-down. Periodic checks on refrigerant levels can lower your energy bills and prevent future repairs. Inspect and Clean Out Condensate Drain Clogged drains can increase the humidity level in extensive water damage. Proper maintenance of the condensate drain can prevent unwanted repair calls. Inspect Blower Wheels Dirty blower wheels reduce air flow, causing longer operating time and increased energy cost. This problem can lead to lost comfort and compressor failure. Avoid wasting your energy dollars by verifying that your maintenance includes a thorough check and cleaning of your blower system. Even New Equipment Needs Maintenance! Some air conditioning and heating problems can double operating costs without reducing comfort. A refrigerant undercharge of only 10% can increase operating costs by almost 20%. A dirty evaporator, condenser and blower could increase air conditioning or heat pump electrical usage by 50% or more. Just 100th of an inch of dirt or film on an evaporator coil can reduce cooling and heating efficiency by 5%. Proper care of your equipment can save you real dollars on your utility bills. All leading manufacturers recommend regular maintenance to maintain peak performance.
