HVAC Maintenance Checklist: What to Do Each Season

hvac maintenance As a homeowner, you know that seasonal HVAC maintenance is crucial for keeping your system running smoothly and your home comfortable. But there’s a lot to keep track of, and it’s easy to miss something that only needs to be done a few times per year. To help out, we’ve created a seasonal HVAC maintenance checklist so you know what needs to be done and when.


As the weather begins to warm up, you’ll probably start thinking about air conditioning maintenance services for your system. Spring is an easy time to get your system checked out and ready for the summer. 

Change your air filters: Change your filters every one to three months, depending on type, usage, and whether or not you have pets.

Check your outdoor unit: Make sure the area around the outdoor unit is clear of debris and vegetation, and clean any dirt or debris off of the unit itself. Check for signs of damage or wear, like cracks or rust. If you find any indications of damage, call a professional to determine if the unit is safe to use. 

Schedule a professional tune-up: Spring is the perfect time to get seasonal HVAC maintenance for your entire system done by a professional from Clay’s Climate Control. Our techs will clean and lubricate components, check refrigerant levels, and ensure your system is ready for the months ahead. 


Summer is one of the worst times to have your AC breakdown. Fortunately, a few simple steps will help keep your unit in good condition so you stay cool and comfortable all summer long.

Check your thermostat settings: Make sure you set your thermostat to the correct temperature and mode for the season. If you have a programmable thermostat, adjust it to account for any changes in your schedule.

Clear the area around your indoor unit: Make sure there are no obstructions around your indoor unit, such as furniture or curtains. This can restrict airflow and reduce your system’s efficiency.

Change your air filters: During the summer, you may need to change your air filters more frequently than in other seasons. Check your filters regularly and change them as needed.


While the focus during spring and summer is on the AC unit, fall is the best time to protect your air conditioning and to get any heating system maintenance done that’s needed. 

Inspect your ductwork: Check your ductwork for any leaks or damage, and seal any gaps or holes. Leaky ducts can reduce airflow and waste energy, leading to higher energy bills.

Test your heating system: Before the colder weather sets in, test your heating system to ensure it’s working properly. If you notice any issues, schedule a repair or tune-up with a professional.

Schedule a professional tune-up: Just as in the spring, fall is a good time to have your HVAC system inspected and tuned up by a professional. 


Having your heat go out during the winter isn’t just inconvenient; it’s dangerous. Keep up with regular heating system maintenance throughout the winter to ensure your system runs smoothly and efficiently. 

Change your air filters: As in other seasons, it’s important to change your air filters regularly during the winter.

Check your thermostat settings: Make sure your thermostat is set to the correct temperature for the season, and adjust it as needed for changes in your schedule.

Test your heating system: Test your heating system periodically throughout the winter to ensure it’s working properly. If you notice any issues, schedule a repair with a professional.
