HVAC: What It Is and How To Maintain It


Most homeowners or renters have probably heard of the commonly used acronym, HVAC, but actual knowledge of what the system is and what you should do to make sure it’s kept in working order may be a little less common. 

HVAC stands for Heating, Ventilation, and Air Conditioning, and refers to the different systems used for moving air between indoor and outdoor areas, along with heating and cooling both residential and commercial buildings. They are the systems that keep you warm and cozy in the winter and feeling cool and fresh in the summer. They also are the systems that filter and clean indoor air to keep you healthy and maintain humidity levels at optimal comfort levels.

As a homeowner, you may have a list of items that you maintain throughout the year, and it should be no different when it comes to your HVAC system. Scheduling regular, preventative maintenance for HVAC equipment with a licensed professional is highly recommended to stay “in the know” about your system and to reduce future costly repairs. 

Once the Texas summer comes around, AC units are on full power and during those winter months furnaces will be run intermittently, so it’s best to check the cooling system in the spring and the heating system in the fall. However, preventative maintenance during any season is better than not at all!

A typical maintenance check-up with your trusted handyman specialist should include the following: 

    • Check thermostat settings to ensure the cooling and heating system keeps you comfortable when you are home and saves energy while you are away.
    • Tighten all electrical connections and measure voltage and current on motors. Faulty electrical connections can cause unsafe operation of your system and reduce the life of major components.
    • Lubricate all moving parts. Parts that lack lubrication cause friction in motors and increases the amount of electricity you use.
    • Check and inspect the condensate drain in your central air conditioner, furnace and/or heat pump (when in cooling mode). A clogged drain can cause water damage in the house and affect indoor humidity levels.
    • Check controls of the system to ensure proper and safe operation. Check the starting cycle of the equipment to assure the system starts, operates, and shuts off properly.
