How Much Space Should I Keep Open Surrounding 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 energy bills are suddenly sky-high, even though you haven’t touched the thermostat.

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

An AC system that runs hot generally doesn’t last as long. And it probably will cost more to cool your Des Moines home.

Heartland Heating & Cooling can help when your air AC isn’t working properly. Or keeping your Des Moines house cool enough.

Space Guidelines for Air Conditioners

So how much space does your air conditioner really call for?

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 obstructions, like a deck or roof overhang.

While doing yardwork, keep your unit out of contact with grass clippings and leaves. Yard waste can obstruct 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 hotter near the coil, your system may have a problem. Call us at 515-344-3579 for help or request an appointment online.

How Much Space Does a Heat Pump Require?

If you live in a temperate climate, you may have a heat pump in place of an air conditioner. This outdoor unit gives both heat and air conditioning for your house.

It needs open space all year, especially if it snows. Remove snow that accumulates on the top and near the sides of the unit.

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