Simple Ways to Minimize Heat Stress on Your Air Conditioning System

posted in: Articles 0

Air conditioning is one of those home systems you think about when it’s not working. Otherwise, when it’s working well, you get busy with your day. Yet your daily activities affect how well your system is working.

Too much heat buildup in your home will make your air conditioning unit work harder. Air conditioning is one of the most expensive systems in your home. When an overworked air conditioning system breaks down, you can end up with costly repairs.

Fortunately, there are very simple ways to prevent heat stress on your air conditioning unit. Keep these in mind as you go about your day. Especially in the summer months, when your air conditioner does the most work.

Don’t Overheat

Do you run a dryer or oven in an air-conditioned space? You may have noticed that when you run these appliances, the air in that room is warm, while the rest of the house is too cold.

These appliances produce a lot of heat. They can trick your thermostat into registering a higher temperature. This causes your air conditioner to work harder than necessary. Plan to use these appliances during a cooler part of the day.

Your thermostat can also be affected by any heat source, like a lamp, placed too closely. Keep all heat-producing items away from your thermostat.

While it’s nice to have your blinds open on a sunny day, intense heat can stress your air conditioning unit. Be strategic about your sunny windows. Try closing the blinds against the most direct sun, even for part of the day. During the hottest days, consider closing blinds in rooms you aren’t using. You will feel more comfortable and your air conditioning unit will not be overworked.

Does the outdoor unit of your air conditioner take direct sunlight during the hottest part of the day? Find a way to shade it – without blocking the air flow.


Poor insulation also causes heat buildup that affects your air conditioner. Check your windows and doors for small openings that cause cool air to escape and heat to come in. Take steps to insulate those areas.

The duct work for your air conditioning unit is often exposed to the hottest parts of your house, especially during the summer. Be sure your duct work is properly insulated to protect from heat.

Keep in mind that heat builds up in your attic too. An attic that is properly insulated can take heat pressure off your air conditioning system.

If you create the right environment for your air conditioning unit, it will create a wonderful environment for you.
