How to Prepare Your HVAC System for Seasonal Changes May 25, 2025

As the seasons change, so do the demands on your HVAC system. Ensuring your system is ready for the switch between cooling and heating modes is crucial for maintaining comfort and efficiency in your home. Preparing your HVAC system for seasonal changes not only extends its lifespan but also helps save on energy costs. Here's how 17 Degrees AC and Heating recommends preparing your HVAC system for the upcoming season so that you can enjoy optimal performance year-round.Start with a thorough inspection, which is the foundation of any seasonal preparation. Routine inspections help identify any potential issues before they become costly repairs. Check your system for visible signs of wear and tear, such as frayed wires or rusting components. It's also essential to listen for any unusual noises that could indicate larger problems. If you are unsure where to begin, a professional HVAC contractor like 17 Degrees AC and Heating can provide a comprehensive inspection and maintenance service.Next, focus on the importance of cleaning or replacing your filters. Dirty filters are one of the most common reasons for decreased HVAC efficiency. They restrict airflow, which can make your system work harder than necessary, increasing energy consumption and wear on the system. Replace your air filters regularly—usually every 1-3 months, depending on the filter type and usage. Clean filters not only ensure efficient operation but also improve indoor air quality, which is especially important as your family spends more time indoors during colder months.Don't overlook the necessity of checking and cleaning your system’s outdoor unit. Over the summer, debris such as leaves, dirt, and grass clippings can accumulate around the unit, affecting its ability to function correctly. Clear away any debris from the unit’s surroundings to promote optimal airflow. Also, take a moment to inspect for signs of damage or wear. Trim any overgrown vegetation to prevent it from obstructing the unit during operation.Ductwork evaluation is another essential step in seasonal HVAC preparation. Leaky or blocked ducts can significantly hinder system efficiency. Conduct a visual inspection of your ductwork and seal any leaks with aluminum foil tape or mastic sealant. Consider hiring a professional to perform a more detailed evaluation if you suspect deeper issues, as HVAC contractors have the tools and expertise to uncover hidden problems.Remember to test your thermostat settings as part of your seasonal checklist. Your thermostat is key in controlling your HVAC system's efficiency and energy consumption. As temperatures start to fluctuate, adjust your thermostat settings for bringing optimal comfort into your space without consuming excess energy. Consider upgrading to a programmable or smart thermostat, which can provide more precise control and present energy savings by adapting to your schedule and preferences.Finally, scheduling a professional maintenance service is an invaluable step in your seasonal preparation. While there are many tasks homeowners can perform on their own, professional technicians have the expertise and experience to conduct a deep assessment and tune-up of your entire HVAC system. 17 Degrees AC and Heating offers tailored maintenance plans that ensure every aspect of your system is ready to transition smoothly between seasons.Proper preparation of your HVAC system for seasonal changes is vital for its efficiency, longevity, and your household's comfort. By performing these essential steps, you can prevent unexpected breakdowns and enjoy consistent performance throughout the year.
