HVAC Checklist for Spring

Spring has finally arrived in Oregon! This means it’s time to give your HVAC system the attention it needs this time of year. Proper maintenance ensures your indoor comfort. It also enhances energy efficiency , reduces utility bills, and extends the lifespan of your system. To ensure your system is ready, we’ve created a comprehensive HVAC checklist for spring!


Change Air Filters

Start the season fresh and new by replacing your air filters. Clogged filters restrict airflow, making your system work harder and less efficient. The type of system you have will determine how frequent you should be changing your air filters.


If you have a ductless mini-split system, as a general guideline, it’s recommended to check the filters at least once a month and replace them as needed. In some cases, filters may need to be replaced more frequently, especially if you have pets, allergies, or live in a dusty area. Regular maintenance of filters ensures optimal performance.


For a ducted/unitary system, the frequency of filter changes depends on many factors such as the type of filter, the level of indoor air pollution, and the system’s usage. Here’s a replacement breakdown for the various types of filters available for these systems:

STANDARD FILTERS: Basic fiberglass filters should be replaced every 1 to 3 months, depending on factors like household size, presence of pets, and indoor air quality concerns.

PLEASTED FILTERS: These offer better filtration and may last longer than standard fiberglass filters, typically needing replacement every 2 to 6 months.

HIGH-EFFICIENCY FILTERS: HEPA (High-Efficiency Particulate Air) filters or other high-efficiency filters might require replacement every 6 to 12 months, but this can vary based on usage and air quality conditions.

REUSEABLE FILTERS: Washable or reusable filters should be cleaned according to the manufacturer’s instructions, typically every 1 to 3 months, and replaced if they show signs of wear or damage.

Additionally, during peak usage seasons or in environments with high levels of dust or pollutants, more frequent filter changes may be necessary. An HVAC technician can provide specific recommendations tailored to your system and circumstances. Learn more about filters in this blog post.

Inspect and Clean Air Vents and Registers

Check all vents and registers throughout your home for dust, dirt, and debris. Use a vacuum or damp cloth to clean them thoroughly. Proper airflow is crucial for even heating and cooling.

Clean Around Outdoor Unit

Clear away any debris, such as leaves, twigs, or grass clippings, from the area around your outdoor HVAC unit. Trim back any vegetation to ensure there is at least two feet of clearance around the unit. This will ensure great airflow and prevents obstruction of your system.

Check Thermostat Settings

Update your thermostat settings for the spring season. If you’ve been using a heating schedule during the winter months, adjust it to accommodate warmer temperatures. Consider upgrading to a programmable or smart thermostat. They provide added convenience and energy savings, too.

Schedule Professional Maintenance

Schedule a spring cleaning for your HVAC system with Associated Heating & Air Conditioning. We recommend having a professional maintenance before the peak cooling season begins. A qualified technician can inspect your system and identify any issues or potential problems. During the appointment, they will perform necessary tune-ups to ensure your system will continue running smoothly.

Consider Indoor Air Quality

Spring is also known as allergy season in the Willamette Valley. This is a huge nuisance for many people. You can track pollen counts on Oregon Allergy Associates website. Consider investing in indoor air quality products, such as air purifiers or UV germicidal lights. This will remove allergens and improve the overall air quality in your home.

Test Your System

Before the weather heats up, test your air conditioning system to ensure it’s working properly. Turn on the cooling mode and let it run for a while to verify that cool air is flowing from the vents. If you notice any issues, such as weak airflow or strange noises, contact our office to schedule a repair.


Taking the time to complete this checklist can make a significant difference in your home’s comfort. It will also increase energy efficiency. By staying proactive and addressing potential issues before they escalate, you’ll ensure a cool and stress-free spring season for you and your family. If you experience any issues with your HVAC system or if you would like to schedule an annual maintenance, call our office at (541)799-2881.
