What to do when it comes to landscaping and yardwork


It’s important to take precautions when landscaping and performing yardwork around your HVAC system. If leaves, weeds, branches, or lawn clippings invade the unit and block the airflow, your system won’t perform the way it should.

Your home heating and cooling system is an integral part of your home—and a fairly expensive appliance to replace—so it’s best to review what homeowners need to know when it comes to landscaping and yardwork.

4 ways to protect your outdoor HVAC unit

Build a border

A dirty condenser coil forces the compressor to work harder than it needs to, increasing energy consumption as a result.

To keep grass from your mower and mud from a rainstorm from clogging the unit, it’s best to surround the unit’s concrete pad with a stone border filled with crushed rock. As a result, rainwater will drain away and foliage will be kept from the unit.

Keep it shaded

Installing the unit where it will be out of direct sunlight helps it run more efficiently.

Shading your house and the HVAC unit is a cost-effective way to reduce solar heat gain in your home and help reduce air-conditioning costs.

Let it breathe

To operate correctly, the compressor needs adequate airflow. Keep at least 2 to 3 feet of space between the unit and any plants or structures. All vegetation should be kept at least two to three feet away from the HVAC unit, and the same goes for structures. There should also be 5 feet of clearance between the top of the unit and any trees above.

Any closer and air flow will be obstructed. This leads to increased energy usage, more repairs, and a shorter system lifespan. All of these things will cost you money—and we know you’d rather spend your hard-earned cash elsewhere!

Plan the plants

If you’re looking to conceal the unit, a hedge is the way to go—as long as you keep it trimmed. It also acts as a windbreak to protect your unit from harsh conditions. Firmly planted evergreens such as Boxwood, Cedar, Cyprus, and Spruce will never lose their leaves.

Falling leaves can impede the fan, so it’s important to select trees that retain their leaves during the winter months. If you have trees on your property that shed their leaves, you need to be on top of raking and trimming.
