Why It’s So Important to Protect Your Outdoor HVAC Units

Outdoor HVAC UnitsOutdoor HVAC units are continuously exposed to the elements and other threats. In most homes, the outdoor central AC is likely the most critical component installed after the shelter and protection of the structure.

Conditions outside can affect air-conditioner performance, efficiency, and even the most basic operational functions. Here are some tips to keep the outdoor HVAC units fully functional and secure in all seasons.

Pick the Right Location

If you’re installing a central AC, situate the outdoor unit for best protection and security.  Don’t put it directly beneath large overhanging limbs that could break in a storm and impact the unit. Also be aware of overhead sources of falling leaves that could block the unit’s condenser fan.

Provide Easy Access

For regular maintenance and when repairs are needed, it’s best to keep 3 feet of open space on all sides of the unit. Fast-growing weeds and encroaching bushes can hinder easy access when you need it most.

Grade the Ground

Don’t install the outdoor unit in a low spot where rainwater may collect. The contour of the ground surrounding the AC should slope away on all sides to prevent pooling water from seeping into internal components.

Maintain Gutters

If the AC component is situated directly beneath roof gutters, make sure the gutters are maintained regularly to prevent overflow. Cascading water from a clogged gutter during heavy rain can damage the unit below.

Prepare for Winter

After the central AC is shut down for winter, an air-conditioner cover sized for your model is available at home centers and online sources. This protects the unit from weather extremes as well as falling leaves and limbs, invading animals, and other potential seasonal damage.

Consider a Cage for Outdoor HVAC Units

Unfortunately, AC compressor theft from outdoor units has become common. Commercially available AC cages permit maximum airflow while preventing component theft and protecting your investment.
