How Much Space Should I Leave Open Around My Air Conditioner?

October 04, 2019

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

Your air conditioner draws in ambient air to cool and lets out warm air as it runs. But it can quickly 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 likely will cost more to cool your Norton home.

HCE Systems Inc can help when your air AC isn’t running right. Or keeping your Norton house comfortable enough.

Space Guidelines for Air Conditioners

So how large of an area does your air conditioner really require?

Here’s what we recommend:

  • 1-foot minimum on all sides, including behind the unit. 
  • 1.5-foot minimum for the sides and an alcove or adjacent wall. 
  • 2 feet between the sides of the unit and tight 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 out of contact with grass clippings and leaves. Yard debris can clog your air conditioner and cause it to overheat.

How to Check 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 an issue. Call us at 276-302-0076 for assistance or schedule an appointment online.

How Much Space Does a Heat Pump Need?

If you live in a mild 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 year round, especially if it snows. Get rid of snow that accumulates on the top and near the sides of the unit.

If your heat pump fills with wintry precipitation, turn it off. Use warm water to melt snow and ice and give the water a little while to drain before putting your system back on.
