Preparing Your HVAC System for California’s Early Spring: A Checklist by Mercury Heating & Air

As the end of winter approaches, now is the time to start thinking about the use of your cooling system. In addition to scheduling an annual AC inspection and tune-up, there are things you can do to prepare for spring and summer air conditioning use. 

The following is an HVAC preparation checklist Concord, CA, residents can use to help ensure their systems are still in tip-top shape:

First on the HVAC Preparation Checklist: Concord, CA Homeowners Must Check the Outdoor Unit

The outdoor compressor is essential for heating and cooling your home, but throughout the year, the area surrounding it can become cluttered with debris, tall grass, weeds, or other foliage. 

Since airflow is essential to the compressor's operation, it’s important to trim the grass and foliage around the unit while also removing debris and anything else that might block the compressor.  A clean area will help your HVAC technician perform thorough maintenance.

Change the Air Filter

Although your HVAC technician will check your air conditioner’s air filter during your annual tune-up, you should still change it out by yourself. It’s a fairly simple task, and by adding it to a comprehensive HVAC preparation checklist, Concord, CA, homeowners will get into the habit of checking and replacing the filter. Additionally, it will ensure efficient cooling if you need to use the system before your scheduled tune-up.

Clean the Indoor Unit

When forming and following any HVAC preparation checklist, Concord, CA, residents should add dusting to their list of tasks. Wipe down the indoor HVAC unit and clear dust from vents and registers throughout the home. 

Removing any dust that might have accumulated will prevent blockages in the system and ensure better indoor air quality once you start using your air conditioner. 

Conduct a Thermostat Test

Finally, check your thermostat for malfunctions. Switch the thermostat’s setting from heat or auto to the cool position, then lower the thermostat by a few degrees. If the cooling system doesn’t start a cycle right away, ask your HVAC technician to check the thermostat for you; it may need calibration or repairs.
