Heating and Air Preventative Maintenance Lessons

HVAC school is in session


HVAC systems are essential to keep you cool during sweltering hot months throughout Alabama. While the systems can seem expensive, they’ve become commonplace in American households. In fact, nearly 90% of new homes are built with central heating and air nationwide.


Think you got what it takes to pass a heating and air studies class? Start taking notes! We’re going to give you a crash course on preventative maintenance.


Heating and Air Strategies to Start Today


  • Purchase the Right Filters. First thing you should know to replace your furnace filter regularly, depending on the type of filter you use. Each product is rated according to an industry scale known as the Minimum Efficiency Reporting Value (MERV) rating.

    These range from 1-16 based on the level of microscopic particles the filter will block. Typically, MERV 8 is standard on most residential furnace filters. This grade normally lasts three months.

    Be advised, use a stronger grade or replace it sooner if you smoke, have a large family or pets. Those with allergies, asthma or other illnesses benefit from regular filter changes too.


  • Control the Thermostat. After your furnace, the thermostat is the next most important piece of equipment. Keep it at a consistent and comfortable level. Keep in mind, the lower the temperature, the more work coils do to cool the air.

    This translates into a higher electric bill at the end of the month. If you decided to lower the temperature, try to do a degree at a time. Drastically lowering the thermostat by many degrees at once will not make it cool any faster. It just wastes energy.


  • Digital Heating and Air Tools. To make the most of temperature control, invest in a digital thermostat. You can program it to automatically adjust the temperature at certain times of the day. Some are Wi-Fi-enabled. This allows you to adjust it remotely using a smartphone app.
