July/Summer Air Conditioning Maintenance Tips

Whether it’s the 4th of July weekend or you plan on taking time off after Independence Day, July is an important time for air conditioning maintenance. A cool home provides relief from outdoor heat, so preventing a breakdown is in your best interest. July is hot for most parts of the U.S. You don’t want to lose your A/C during a summer heat wave, when hosting guests in your home, or in the middle of the night.

Maintenance helps avoid these circumstances. It also helps keep indoor air clean, improves energy consumption and performance, and can save money on your energy bill. Here are a few tips to help you as a homeowner keep your HVAC system working through the summer, so your family and guests stay comfortable:


Increased usage means the air filter may need to be replaced sooner than usual (sometimes in as little as a month). Changing it is one of the simplest A/C tasks. With a new filter, the unit may use less electricity, improving its efficiency—all after a few minutes’ work.


Check each register and grille for any blockages. If a vent is blocked, it will restrict airflow, which can result in overheating and other issues in the cooling system. Clear dust that has collected and open any vent louvers that are closed. If any furniture or carpets are blocking vents, move them away, or avoid placing anything there in the first place, to improve airflow. Contamination deep in the system can affect performance and indoor air quality, so if performance issues or respiratory symptoms persist, or it has been a while, consider having a professional duct cleaning.


Vegetation, grass clippings, leaves, and other types of debris can affect how your outdoor unit performs. Remove anything that has accumulated on the unit and avoid storing outdoor furniture too close to it. If the A/C isn’t working, first check that any power switches aren’t in the off position. Sometimes the power is switched off by accident. If you have an older unit with performance issues or that requires frequent repairs, consider replacing it with a newer, more efficient product such as an Energy Star-rated air conditioner.


The thermostat controls your entire HVAC system. It’s important that any thermostats connected to it are turned on. Also, set the fan to AUTO; if you keep the fan setting at ON, it will run continuously even if the A/C isn’t cycling, using more power than necessary. And, if your home isn’t at the right temperature, check the thermostat’s batteries and replace them if they’re old or dead.


A ceiling fan circulates air, which helps reduce the demand for your air conditioner. The A/C can therefore cool your home with less energy. You’ll also get a nice, gentle breeze as warm air rises, causing cooler air to replace it below. An affordable alternative, floor fans can do a good job at keeping air moving at floor level. With any fan, you may experience the same comfortable temperature even if the A/C isn’t set as low.
