Just like any other piece of equipment, the HVAC unit needs regularly scheduled preventative maintenance to keep it in tip top shape. Get into the habit and ensure that the equipment lasts longer. When an HVAC unit runs in optimal condition it saves on expenses today and down the road. Preventative maintenance will catch any potential problems and issues early, and avoid a more complicated and costly repair job in the future.
What are the Homeowners Responsibilities?
Most homeowners take care of little things such as making sure that all weeds and grass are kept trimmed around the outdoor condenser unit. The unit should be checked frequently for surface debris which is easy to remove. Changing the unit filters on a monthly basis should be done. The best type of replacement filter is an electrostatic one. A clogged unit filter will drastically reduce the efficiency of the HVAC unit and will result in higher energy costs. Never run the unit without having a filter inside. With the power turned off, clean the condenser blades and the fan before the cooling season begins to help keep it running efficiently. Check the base pan under the unit and replace it after a thorough cleaning. Once per year, lubricate the fan motor if it has ports for oil. In the long months of winter, keep the outdoor unit covered for protection and shaded if possible in the summer months.
Have Yearly Inspections of Your System
Ideally, at least once per year a licensed HVAC technician should come to your home to professionally inspect and clean the unit to ensure optimum efficiency of the HVAC. The technician will check refrigerant pressure, clean the condenser coil, inspect electrical connections, check the air filter, clean the drain on the compressor, clean the evaporator coil and thoroughly clean the entire HVAC unit. If it is a gas unit, the technician will check all safety controls, clean the flame sensor and the burners, and check the gas heat exchanger. Upon completion, the unit will be ready to go for the season, whether winter or summer.
Professional annual or semi-annual maintenance will benefit the homeowner with a monthly energy bill reduction, a longer life span of the HVAC unit and the peace of mind that comes from knowing it was all taken care of by a professional and qualified technician.
