Air Conditioner

How Much Space Should Stay Open Surrounding My Air Conditioner?

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

Your air conditioner draws in ambient air to cool and forces 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 probably will cost more to cool your Franklin Lakes home.

Total Comfort can help when your air AC isn’t functioning properly. Or keeping your Franklin Lakes house cold enough.

Space Guidelines for Air Conditioners

So how much room 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 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 waste can congest 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 something wrong with it. Call us at 201-268-5663 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 creates both heat and air conditioning for your space.

It needs open space all year, especially if it snows. Get rid of snow that builds up 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 few minutes to drain before switching your system back on.
