Professional technicians know that air conditioning units should have enough clearance around them to ensure proper operation while prolonging their lifespan. But how much clearance should your unit have? It depends on what’s closest to it. Here trusted air conditioning replacement contractor Air Pro Inc. shares what you need to consider:
While your unit’s manufacturer may have specific clearance recommendations, there should be at least one foot (12 inches) of clearance on each side of your air conditioner. The top of your unit, however, should have at least 60 inches of vertical clearance so that it has enough room to circulate air in and out. When it comes to indoor units, having one installed too near a ceiling will force it to pull in warmer air, making it operate less efficiently than intended. This means you’ll see an increase in your monthly energy bill while your air conditioning unit deteriorates faster than normal.
Professional air conditioning repair technicians know that you can still get minimal clearance without affecting your outdoor unit’s expected lifespan if you have landscaping such as shrubbery shielding it. So long as it isn’t too dense, air can easily pass through the foliage even if it’s a mere six inches away from your unit. However, keep in mind that shrubs grow over time, so they’ll need to be trimmed occasionally. If they grow too close to your unit, they’ll become an obstruction that will limit airflow.
If you’re planning to install your unit in a deck area, make sure there aren’t any obstructions and that you have enough clearance above it. This is especially important if you have a unit that discharges warm air from the topside. Any blockage will result in some of the warm air being drawn back to the intake, which can cause your condenser coil to overheat.
