Things To Know About AC Installs

Unlike a furnace, air conditioning units can break down without warning. Often, it can be costly to fix an air conditioner, so clients choose to invest in a new one instead. In the Summer, replacements can book up very quickly, so we recommend testing out your air conditioner in the Spring & getting it replaced before the summer heat arrives.

Maintaining your air conditioning

Your air conditioning should be maintained by a professional once a year, just like your furnace! As a homeowner, there are some things you can do to get the longest lifespan out of your air conditioning.

Air Conditioning Tips:

Test it out in the Spring

Make sure everything is in good working order before the heat of the Summer so if you need any repairs, you can have it repaired in a timely manner.

Change your furnace filter

Yes, the same blower motor in your furnace is the same fan that pumps cold air through your home from your AC. Be sure to keep a good routine with your filter at all times of the year!

Clear the area around your AC unit outside

The immediate area around your AC should be clear of any long grass, plants, bushes, or trees to ensure proper cooling and sufficient airflow. Also, clear out any leaves that may have fallen around it, so they do not get sucked into the AC system.

Check your AC controls are working

The AC needs to run through a full cycle, starting, cooling, and stopping when controlled at the thermostat. Make sure to check the batteries in the thermostat too. Most thermostats have batteries, while some do not. You could add this to your annual Spring cleaning checklist.
