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 utility bills are suddenly skyrocketing, even though you haven’t moved the thermostat.

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

An AC system that runs hot normally can’t last as long. And it probably will cost more to cool your Los Angeles home.

AZ Air Conditioning and Heating can help when your air AC isn’t running properly. Or keeping your Los Angeles house cool enough.

Space Guidelines for Air Conditioners

So how much room does your air conditioner really require?

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 dense 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 debris 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 higher near the coil, your system may have something wrong with it. Call us at 800-296-5088 for a helping hand 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 rather than an air conditioner. This outdoor unit gives both heat and air conditioning for your space.

It needs open space at all times, especially if it snows. Clear away 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 a few minutes to drain before turning your system back on.
