Clear Debris
The first thing you should do is clear the debris and dirt that has accumulated on your coils and fans.
- Gentle brushes, rags or vacuum cleaner attachments are usually good tools for the job.
- Always consult your owner's manual to avoid the potential for damage.
- Never use coarse brushes or your water hose to clear the debris, because they can cause damage to the machine.
Check for Leaks and Cracks
Water should never be allowed to build up on or around the machine during the winter. When temperatures get below freezing, water will freeze and can cause severe damage to your air conditioner if it is caught in leaks or cracks. Inspect the outdoor unit for damage, and get professional help if you find any.
Clear the Ground Around the Unit
Snow can become a big issue for A/C units if moisture is allowed to collect in and around them. Clear any intrusive grass growth and over-hanging bushes and trees. Then, remove leaves from the gutters above the unit. These actions will help to prevent moisture from dripping into the system, freezing, and damaging the fan and coils. If ice does develop, call in a pro to asses the situation.
Cover the Air Conditioner
If you have an older machine, it may be a good idea to cover it, but new models are usually designed to remain uncovered, even during the coldest months. As with clearing the debris, you should refer to your owner's manual to see if the manufacturer suggests covering the A/C unit or leaving it uncovered.
