Preparing Your HVAC System Maintenance Checklist for Cooling Season

 In Air Conditioning

Summer heat is in the air and the time to prepare your HVAC system for the coming summer season. However, many homeowners have not put getting their HVAC system ready at the top of their priority list.

The season is full of flowers and celebration, yet also brings pollen and other allergens. If you typically have allergies during this season, then you can relate. When airborne allergens get introduced to HVAC systems, it can make for a house fulls of headaches and stuffy noses.

This is the time to schedule a professional air conditioning tune-up to maximize unit efficiency and extend unit life. You are also guaranteed a greater efficiency and a healthier environment simply by having your HVAC cleaned, checked, and maintained regularly.

To ensure your HVAC system is prepared, here is a maintenance checklist to review:

Air Filter

Air filters are key to maintaining healthy indoor air quality. If the air filter is dirty, the air is dirty. Additionally, if the air filter is dirty, then it is harder for your air conditioner to do its job; resulting in poor airflow, more wear and tear, and higher energy costs.

Use the change in seasons as an opportunity to change out the air filter. Air filters should be replaced according to need and use, typically every season.

Clean Around the Unit

Do you ever pay attention to your outdoor unit? Every once in awhile, it needs to be checked up on. It’s possible that over the winter months, overgrown foliage, trash or other debris could have found its way in or around the condenser unit. Keep the area around the unit clear to prevent any issues. There should be a minimum 2-foot clearance around the entire unit. Be careful when planting around your HVAC unit—think about how large your plants will grow. A clean and clear unit is essential for maintaining high efficiency levels and reliability. HVAC technicians also appreciate the clear path.

When clearing the area around your unit, you may possibly notice a pest that has found its way inside. Turn the system off and contact an HVAC technician right away if you suspect that an animal could be in your unit.

Indoors, make sure there is nothing located near the vents, registers, or indoor air handler. The key is to keep the air flowing as free as possible around your HVAC system.

Set Dampers

Many houses built since 1990 have high and low air returns. During cooling season, the high return should be open and the low one closed. In the heating months, the high one should be closed and the low should be open. This allows for better air mixing.

Thermostat Upgrade

Your thermostat has been set to “HEAT” for months now. As heating season transitions to cooling, be sure to switch over to the “COOL” option. Easily control the temperature of your space whether it’s day or night, whether you’re headed to work or headed to bed. Smart thermostats offer energy savings by learning your unique schedule, self-correcting, and providing energy tips and reports.
