How Much Space Should Stay Open Around My Air Conditioner?

You probably don’t think too much about your air conditioner until it’s not working right. Or until your utility bills are suddenly climbing, even though you haven’t changed the thermostat.

Your air conditioner draws in the surrounding air to cool and expels warm air as it function. But it can easily overheat if it can’t get enough surrounding air or flush out hot air.

An AC system that runs hot usually doesn’t last as long. And it doubtlessly will cost more to cool your McHenry home.

Jett's Heating & Air Inc. can help when your air AC isn’t working correctly. Or keeping your McHenry house cool enough.

Space Guidelines for Air Conditioners

So how much room does your air conditioner really need?

Here’s what we recommend:

• 1-foot minimum on all sides, including the rear. 
• 1.5-foot minimum for the sides and an alcove or adjacent wall. 
• 2 feet between the sides of the unit and thick shrubs or solid fences. 
• 6 inches between the sides and leafy plants, with a few extra inches left for growth.
• 8 feet between the top and blockage, like a deck or roof overhang.

While doing yardwork, keep your unit clear of grass clippings and leaves. Yard waste can congest your air conditioner and cause it to overheat.

How to Find Out if Your Air Conditioner is Overheating

1. Turn the air conditioner on.
2. Check the temperature a few inches from the coil. This is the metallic grate that surrounds your unit.
3. Measure the temperature 10 feet away.

If the temperatures are the same, your system is working properly.

If the temperature is warmer near the coil, your system may have a problem. Call us at 815-410-1128 for a helping hand or request an appointment online.

How Much Space Does a Heat Pump Have to Have?

If you live in a moderate climate, you may have a heat pump rather than an air conditioner. This outdoor unit provides both heat and air conditioning for your home.

It needs open space all year, especially if it snows. Get rid of snow that builds up on the top and near the sides of the unit.

If your heat pump fills with wintry precipitation, switch it off. Use warm water to melt snow and ice and give the water a few minutes to drain before turning your system back on.
