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 correctly. Or until your energy bills are suddenly skyrocketing, even though you haven’t moved the thermostat.

Your air conditioner draws in ambient air to cool and lets out warm air as it works. But it can promptly 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 likely will cost more to cool your Carson City home.

Anderson Heating & A/C can help when your air AC isn’t functioning right. Or keeping your Carson City house comfortable enough.

Space Guidelines for Air Conditioners

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

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 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 scraps can congest 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 warmer near the coil, your system may have a problem. Call us at 775-230-7628 for help or request an appointment online.

How Much Space Does a Heat Pump Require?

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 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, switch it off. Use warm water to melt snow and ice and give the water a little while to drain before turning your system back on.
