How to Prep Your HVAC Unit for the Spring and Summer

Spring has arrived, and that means the cooling season isn’t far away, especially in some of the warmer parts of the United States. Before the cooling season arrives, it’s a good idea for you to perform some basic maintenance and preparation on your HVAC unit to make sure your equipment is ready for the season.

Here are a few HVAC checks and maintenance tips for the upcoming spring and summer seasons in St. Louis, MO:

  • Take off lids and covers: Some people cover their exterior units in the winter months to give them some extra protection. If you did so, make sure you remove that cover before you start up the system for the first time this year. Keeping those covers on during operation could limit heat transfer and potentially damage the system. There are many people who forget to remove their covers each year, which can result in some expensive repairs.
  • Inspect the exterior unit: Take a look at the exterior air conditioning unit, and particularly its panels, which are designed to protect the electrical connections. If you’re missing a panel, or if one is misaligned or damaged, you’re going to want to make sure you get a technician out to fix the issue as soon as possible.
  • Remove debris: The outdoor condenser can easily trap trash that blows against it, and could also be susceptible to vegetation growth. Make sure to remove any debris or vegetation that grows into or around it. Once you start mulching for the season, avoid packing mulch around the unit’s base, because this could prevent good airflow from occurring.
  • Change filters: You must change the air filter in your indoor air handler several times a year, and the change of seasons is a good time to do this. This is especially important after the winter, when you’ve likely been running your system much more frequently and thus are more likely to have a significant amount of debris built up in the filter.
  • Check drainage: There should be a coil drainage hose or condensate line inside. The coil’s temperature will usually be lower than the ambient air around it, which means water will condense on it and drip into the condensate tray. That condensation must flow to a drain, or else the tray will fill up and potentially spill water on to your basement floor. It’s important to make sure your drainage system is functioning properly.
  • Clean vents and air returns: This is a task you should take on several times a year, and it makes sense to do it when switching from heating to cooling and vice versa. Supply and return air grills and vents should be opened up and cleared of dust or debris. You can use vacuums with hoses to get inside and remove debris that accumulated during the winter. This will help ensure the delivery of clean air throughout the coming season.
