Prepare Your HVAC System for Spring

As the days and nights get warmer this spring, your attention shifts from heating your home to cooling it. Getting your heating and cooling equipment ready for the changing seasons is crucial if you hope to maintain home comfort and energy efficiency. Follow these HVAC system transition suggestions from the HVAC specialists at Mid-State Air Conditioning, Heating & Plumbing to make sure your AC is primed and ready for the warmer months ahead.

Inspect the Air Filter

Your HVAC filter slowly traps dust, pollen and other particles, minimizing airflow. This requires your system to work harder. Ideally, you should replace the filter every three months or less, with exactly how often you change it determined by your system usage and filter type. Choose the recommended size and efficiency rating for your system, since using an incorrect filter can overly restrict airflow and reduce efficiency. If you’re uncertain which filter to buy or how to install it into your system, ask your HVAC technician during your next scheduled maintenance appointment to demonstrate.

Inspect the Outdoor Condensing Unit

The outdoor part of your AC system that releases hot air, also known as a condensing unit, is a fundamental part of the cooling process. Here’s how to get your exterior AC equipment ready for another summer:

  • Take off the AC cover: If you threw a cover or board over your outdoor unit to protect it during the cold months, remove it before powering up the air conditioning for the first time this spring.
  • Clean the unit: Over the fall and winter, your outdoor unit may have become covered in leaves, dirt and other clutter. You can give it a good rinse with a garden hose to get rid of this buildup.
  • Remove nearby debris: The area in the vicinity of your outdoor unit must remain clear for optimal airflow. Clear away leaves, pine needles and other debris close to the unit. Also, trim nearby vegetation to make sure you have at least 12 to 24 inches of clearance on all sides.
  • Make sure the unit is level: The concrete pad your condensing unit is situated on may shift or settle through the years, causing the unit to tilt. To protect against improper operation and premature wear, adjust the unit by wedging shims underneath its base. Verify your adjustments with a carpenter’s level.

Increase the Temperature on the Thermostat

Change your thermostat to a comfy yet energy-efficient temperature. For the hotter months, 78 degrees F is advised while you’re going to be home. If you feel too hot, turn on the ceiling fan to make the room feel cooler without turning down the thermostat.

Boost the temperature by 7 to 10 degrees when the house is empty during the day to reduce your energy bills. To avoid compromising comfort, install a programmable thermostat and set it to resume to a comfortable temperature when you come home. This strategy saves up to 10% on your air conditioning bills.

Assess and Clean Your Air Registers

Dust, pet hair and other airborne waste can build up on supply and return registers, hindering airflow. Use the brush attachment on your vacuum cleaner to clean out this mess. After that, make sure all your vents are open and not covered up by things like rugs or curtains.

Despite what some have been told, closing vents in spare rooms does not save energy; all it does is disrupt the system’s return/supply balance. To prevent undue strain, keep at least 80% of your supply registers open and unblocked at all times.

Locate and Close Air Leaks

Leaky windows, doors and other openings enable hot, humid air to sneak inside your home. To fix this concern, inspect window and door seals, using caulk and weatherstripping to seal any holes. Next, inspect the attic for insufficient insulation or gaps around pipes, ductwork and light fixtures. Seal these leaks with spray foam and top them with additional insulation to reduce unwanted air exchange through the attic floor.

Run a Test Cycle

Before the season warms up, operate your AC for a couple of minutes. Walk around your home and make sure cool air flows effortlessly from each and every vent. If you see anything wrong, schedule AC repair to nip the problem in the bud.
