Minimize Summer Strain on Your HVAC System

Feb 22, 2023

During the heat of summer, air conditioning is our best friend. It keeps us cool, comfortable, and mentally and physically alert.  There are several things we can do to minimize the strain on our HVAC system.  Here’s how to minimize summer strain on your HVAC system

Annual HVAC Checkup

The best way to ensure your AC is in top condition is to schedule a checkup.  Keeping up with routine maintenance will make a big difference.  Call a professional. They can recognize and diagnose potential problems before your AC calls it quits.

Pay Attention to HVAC Filters

Take proper care of your filters.  This is the most effective way to keep your HVAC healthy.

Get familiar with the type of filter your unit has. Read the instructions for cleaning and changing it.  If the filter is reusable, vacuum and rinse it between maintenance visits.   Make sure to replace them every few years.  Get into the habit of checking your filter at least once a month.  A clogged filter is far less efficient and will shorten the lifespan of your system.

Keep the Heat Out

To reduce stress on your AC unit, do your best to keep the heat outside.  Use quality windows or blinds to keep heat from circulating into your home.  Remember to close the blinds or curtains when you are gone.  Grill outdoors more often to avoid using a hot oven that will heat up the house.

Avoid opening your doors and windows too much. Your HVAC system will have to work harder to keep the indoor temperature steady. Also, seal any openings that may be allowing cold air to escape. Look for cracks or gaps in your windows, walls or doors.

Get an Attic Fan

When heat gets trapped in the attic, it leaks into the rest of your home.  This causes your AC to work overtime.  Save money on your electricity bill by using an attic fan.

Adjust the Thermostat

When you are out, make sure your home thermostat is properly set.  A smart one allows you to control the temperature inside your home with a mobile device. Turn it to the temperature you want before you return. If you don’t have a smart thermostat, set your unit to a higher temperature while you’re not home.  The Department of Energy recommends you keep your thermostat at 78 degrees during summer.  Turn it up several degrees to save money when the house is empty.

Clean the Vents

Dust and debris that builds up can keep air out of a room.  Keep your vents clean to allow air to flow.  Keep vents open, but close the doors to rooms you aren’t using.  This will let the room more quickly reach the desired temperature.  Also, make sure the outdoor area by your AC unit is clear.  Debris, plants, tall grasses and weeds can all block airflow and keep your unit from working efficiently.

Common Causes of a Broken AC

Aside from dirty filters, a refrigerant leak can lead to a breakdown.  WIthout refrigerant, the temperature in your home can’t be properly controlled.  Evaporator coils help remove hot air from your home. If they get too cold and freeze, they won’t function properly.  A faulty thermostat can cause your AC to turn on and off frequently.  A bad blower fan that can’t get the cool air into your home is useless. Neglecting maintenance is a key cause of AC failure.  Stay up-to-date with your annual checkups.
