How Much Space Should Stay Open Around My Air Conditioner?

October 04, 2019

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

Your air conditioner draws in outdoor air to cool and expels 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 usually won’t last as long. And it doubtlessly will cost more to cool your Des Moines home.

Kohles & Bach Heating & Cooling can help when your air AC isn’t functioning correctly. Or keeping your Des Moines 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 back. 
  • 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 interference, like a deck or roof overhang.

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

How to See 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 higher near the coil, your system may have a problem. Call us at 515-207-6569 for assistance or make an appointment online.

How Much Space Does a Heat Pump Need?

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

It needs open space year round, 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, turn it off. Use warm water to melt snow and ice and give the water some time to drain before putting your system back on.
