Prepare Your central AC for Hot Summer Days

Preparing your central AC is preparing your home for summer, because when hot summer days come around, you’re going to want a place to beat the heat.

There are a few routine household maintenance chores that need to be done to prepare your central AC for hot summer days.

  • Check your thermostat: Install fresh batteries in your thermostat for the central AC hot summer season. If you have an older, mechanical type thermostat, you may want to consider upgrading to a programmable model.
  • Check Wiring and Components: Start by turning off the power to the unit. Check any electrical connections to make sure they are tight.
  • Clean the Coil: Coil helps to move the hot and cold air, so you want to make sure that they are not clogged with dirt and dust. In a central AC system, you can easily clean the outdoor condenser unit before you get a professional to inspect the rest of the parts. Make sure that any debris and residue is cleaned off and removed from your unit and its coils to keep it running efficiently. Dirt and debris can cause breakdown of the unit, costing you a lot of money in repairs.
  • Change the filters: Maintaining a central AC unit is all about maintaining airflow. Air filters built up dust and grime over winter months. That is why it is important to regularly change the air filter on the system.

Always observe safety precautions. Before you perform any work on your outdoor unit, always shut down the power to the unit at your electrical box first.

Properly maintaining your central AC unit will be of great benefit in terms of saving money, saving energy, and keeping you comfortable during the hot summer days. Best is to get a regular maintenance check and cleaning done on the unit by HVAC professionals. Professional HVAC team inspects the control box; coils; fan motor and blades; compressor and tubing. Additionally, refrigerant levels are inspected and adjusted if necessary.
