A/C Operating Tips that Keep Northeast Ohioans Cool and in Energy-Saving Mode

Posted by Paul Wadsworth on Wed, Aug 15, 2012 @ 02:08 PM

Here are three reasons why these A/C operating tips may be of interest: June, July and August. In Northeast Ohio, these months have average high temperatures above 80 and average relative humidity exceeding 70 percent. Figures like this are in the uncomfortable range for most homeowners, particularly indoors. Air conditioning units operate on relatively narrow margins of efficiency and performance and require seasonal maintenance. It doesn’t take much to throw the system out of balance and cost you more money from wasted energy and/or decreased comfort levels.

Make sure you get peak performance during peak season by following these basic A/C operating tips:

Filter change

energy efficient summer acAirflow is the heartbeat of your central A/C system. The list of malfunctions and poor performance caused by low airflow is long. Changing the filter is quick and easy. If you are using a basic filter, some manufacturers recommend a filter change every other month. During summer, be safe and change it monthly. Some more expensive, higher efficiency filters can last much longer, so make sure to ask your HVAC technician his recommendation for your system.

Evaporator coil

The evaporator coil in the indoor air handler is often inaccessible to the homeowner. However, if you’re experiencing icing or freeze-ups of the coil or low airflow issues, this is a good time to have an HVAC technician check the coil and clean it if needed.



A higher thermostat setting — 78 to 80 degrees — saves money and actually makes cooling more consistent by reducing frequent on/off cycles of the A/C unit. Use fans to redistribute cool air to warmer parts of the home if necessary.

Outdoor components

The condenser coil in the outside cabinet disperses heat extracted from your home, so it’s important to keep it clean and maintain airflow around the cabinet. Cut any encroaching vegetation back to allow 2 feet of free space on all sides. Turn off power to the outdoor unit and take off the protective grille. Sweep out any grass clippings or leaves and squirt water from a garden hose through the coil from the inside out. Replace the grille and turn the power on.
