How well you protect and maintain your heat pump’s outdoor unit (also known as the compressor) plays a big role in how long it will last and how efficiently it will heat (and cool) your home. Heat pumps are unique in that they are a space heating system partially located outside of your building. Keeping the effects of weather at bay will go a long way to providing you with inexpensive and clean heating and cooling year round.
Build a Roof!
One of the best defenses against rain, snow, and roof avalanches is building a small roof to shelter your unit. This can be as simple as a piece of plywood with metal roofing attached to the side of your home.
Without protection, snow and water can melt and freeze onto the compressor, blocking airflow and reducing efficiency. In addition your equipment will last longest when kept dry, preventing rust and water intrusion that can damage internal components.
Does Your Compressor Need a Cover?
Ask yourself these questions:
- Is the furthest edge of your compressor well-covered by your building’s eaves?
- Is the unit protected from wind that could blow rain and snow onto it?
- Does your unit stay dry during rain or snow?
If you answered “No” to any of these questions, your compressor would likely benefit from a cover!
Best Practices for Your Compressor Cover
- Allow for airflow – Place the cover high enough above the unit to ensure good airflow around all sides of the outdoor unit
- Provide adequate overhang – If possible, extend the cover at least 1 foot past the front of the compressor and 1 foot beyond each side
Protecting your heat pump’s outdoor unit is a simple investment that pays off in longer equipment life, reduced maintenance, better heating performance, not to mention good old peace of mind. Call any of your local heat pump installers to inquire if they provide compressor coverings or search online for creative options to make this your ‘should’ve done it yesterday’ DIY project.
