Crucial Routine Maintenance for HVAC Systems

  • Replacing the Air Filters

    This is the first stop for air conditioner maintenance. Regularly replacing the air filter is not merely a suggestion, but a requirement for the HVAC unit to run properly and efficiently. The air filter is responsible for removing harmful dirt and other particulates from the air. This protects the system from being damages by debris, the air handler and ducts from becoming clogged, and ultimately keeps dust and dirt from redistributing throughout the home.

    You’re A/C’s filter should be replaced at least every month, depending on use. If you have pets it is wise to check the filter every couple of weeks and potentially replace it just as often. It might also be beneficial to invest in a high-quality air filter that can filter out more particulate matter from the air.

  • Condensation Drains

    As your HVAC system’s coils heat or cool a space, the moisture in the air passing over the coils turns to condensation and needs to be drained from the system. The condensation falls into drainage pans and ultimately is carried out of the house. Over time these drains can become clogged by dirty water and when they do, the drainage pan can very quickly overflow.

    The resulting damage can destroy not only your system but surround walls, floors, and ceilings depending on where the air handler is located in the house. A professional air conditioning repair service should regularly check your HVAC drainage systems for clogs.

  • HVAC Coils

    Making sure to replace clean filters regularly can prevent dirt build up on the evaporator coils for a long time. Though eventually residual dirt will collect on the coils. This dirt will prevent air from being cooled as it passes through the coils. An air conditioner repair contractor should be considered when the coils need to be cleaned. Professional technicians are experienced in proper cleaning procedures for the coils.

    Cleaning agents should never be used to clean the evaporator coils. The residue from these chemicals can cause gradual degradation of the coils or even corrosion over time. Then you will really need an AC repair service.

  • When to Call in the Professionals

    HVAC systems have several moving parts and not all of them are easily accessible. And, depending on where the heating and air system is located, it may be difficult to perform some maintenance on your own. Here are a few reasons a professional should be called in:

    • Checking Seals for leaks: This requires some disassembly of the system as well as a trained eye. Never attempt to take apart you HVAC on your own.
    • Check and Refill Refrigerant: These steps require specialized equipment and gauges. The refrigerant is also not always readily available to consumers.
    • Motor Maintenance: A technician should lubricate or oil the motor as well as ensure any motor belts are in good condition.
    • Thermostat Maintenance: Your air conditioner service should routinely check to make sure the thermostat’s thermometer readings are accurately measuring the ambient temperature. This will prevent the system from heating and cooling too much or too little while also saving you money on energy costs.
