April is a great time to get your HVAC system serviced. You’ll probably need to turn it on very soon (if you haven’t already) and beating the summer rush is nice as you’ll have an easier time booking a service appointment. Not to mention you want to make sure your system is working at optimal levels before the heat hits for real.

If your AC units are relatively new, you may have a service plan with the company that installed them. Some businesses offer service plans for a couple years at a discounted rate, but you typically have to buy them at the time of installation. If you didn’t do this, no need to fret, as any heating and air conditioning company can perform routine maintenance services. Check with neighbors for a recommendation or look at the Better Business Bureau or Angie’s List websites to find a reputable firm.

When you book the service, be sure to tell them if you’ve experienced any issues in the past. They will likely have you turn the temperature down a few degrees when they arrive so that they can see the unit in action. A basic service includes a visual inspection of the outside unit(s) as well as the parts in your attic. They will be cleaned, electrical connections checked, drains cleared, joints lubricated, and refrigerant levels checked. The coils on the evaporator and the condenser should be cleaned to increase the efficiency and lifespan of your unit.

You should also have the technician examine the blower and heating element to ensure proper airflow and safety.

This is also a great time to have your air filters changed. It is recommended to do this about twice a year. With the high pollen levels that we’re experiencing lately, getting the dust and pollen spores out of your HVAC system will improve the air quality inside your home.
