How Much Space Should I Keep Open Around My Air Conditioner?

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

Your air conditioner draws in ambient air to cool and expels warm air as it works. 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 Cambridge home.

Pliescott HVAC Services LLC can help when your air AC isn’t functioning properly. Or keeping your Cambridge house comfortable enough.

Space Guidelines for Air Conditioners

So how much space does your air conditioner really need?

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 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 clear of grass clippings and leaves. Yard debris can congest your air conditioner and cause it to overheat.

How to Find Out 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 410-228-4822 for help or make an appointment online.

How Much Space Does a Heat Pump Need?

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

It needs open space at all times, 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 switching your system back on.
