Reliable AC & Heating Experts

As fall settles in around Lowell and Gaston County, the days and nights bring fluctuating temperatures: warm afternoons, cool evenings, even sudden cold snaps. If your home uses a heat pump or a dual-mode HVAC system (heat pump + auxiliary heat or furnace), that “shoulder season” demands more attention than many homeowners realize. Here’s how to optimize performance, cut costs, and protect your system during fall’s temperature swings: 1. Use the “Auto” or “Heat / Cool” Mode Wisely Many thermostats let you set “Auto” or alternate between heating and cooling modes. During fall, this can save you from constant manual switching. But: Make sure your thermostat’s temperature differential (the margin where it decides to switch) is reasonable to avoid short-cycling. If your system offers a *“dual-fuel” or “hybrid” setting (heat pump plus gas or electric backup), ensure it’s configured correctly for your climate so the backup heat doesn’t kick in too soon. 2. Monitor & Program Your Temperature Bands The goal is to let the system run longer, more gently, rather than short bursts. To do that: Widely thermostats unintended to fluctuate by 2–3 °F before switching modes (for example, set heating trigger at 65°F, switch to cooling only above 78°F). Use thermostat scheduling to lower or raise temps when no one’s home (or overnight). If you have a WiFi/smart thermostat, review your run history at the end of the season—in patterns you might adjust next year. 3. Keep Your Outdoor Unit Clear Leaves, twigs, grass, and other debris tend to accumulate around your outdoor unit this time of year. Even small blockages in airflow can strain your heat pump when it’s asked to both heat and cool. Clean gently with a leaf blower or soft brush. Trim back shrubs or overgrowth to ensure at least 2 feet of clearance. During storms, check the unit for debris afterward. 4. Change or Clean Filters More Frequently Because fall is a transitional season, your HVAC may run in both heating and cooling modes. That means your filter is more likely to accumulate dust, pollen, and debris faster. Check filters monthly—even if you typically wait longer. Use high-quality pleated filters (MERV 8–13) compatible with your system’s airflow. Dirty filters reduce efficiency, cause strain on the blower, and can push the backup heating mode to engage more often. 5. Defrost Cycles: Know What’s Normal Heat pumps periodically go into defrost mode when frost forms on the outdoor coil. This is normal. But: If your unit is constantly freezing or defrosting (especially when temps are above freezing), that could signal airflow problems, sensor issues, or refrigerant imbalance. Any extended ice buildup is a warning sign—call us before it damages core components. 6. Seal & Insulate Your Ductwork With temperatures fluctuating, your system is working harder to maintain comfort. Leaky ducts waste conditioned air, make the system run longer, and can accentuate the climate roller coaster inside your home. Inspect visible duct runs (attics, crawl spaces, basements) for loose connections, gaps, or unsealed joints. Use foil-backed mastic or HVAC tape (UL-approved) to seal leaks. Insulate ducts in unconditioned space to reduce heat loss/gain. 7. Schedule a Tune-Up Before Heating Demands Rise Fall is the ideal time for a full HVAC tune-up—before you rely on heat heavily. A technician from Native Air will: Test and calibrate your defrost sensors and controls Check electrical components, capacitors, and wiring Verify refrigerant levels and check for leaks Inspect backup heat or auxiliary strips Monitor system pressures in both heating and cooling modes Catching minor issues now can prevent breakdowns mid-winter or mid-heat wave.

As we transition from the heat of summer into the cooler days of fall here in Lowell, NC, it’s the perfect time to give your HVAC system some attention. While many homeowners focus on spring maintenance, fall offers a unique opportunity to ensure your system runs efficiently through the upcoming heating season and beyond. A little preparation now can save you from costly repairs, improve energy efficiency, and keep your home comfortable year-round. Why Fall Maintenance Matters Prepare for Seasonal Changes: HVAC systems can be stressed by sudden temperature shifts. Fall maintenance helps your system handle cooler nights and fluctuating temperatures without overworking. Catch Minor Issues Early: A routine check can identify small problems before they become major headaches. Addressing these early can save you time, money, and stress later on. Boost Efficiency and Lower Costs: Systems that are clean and well-maintained operate more efficiently. That means lower energy bills and a reduced environmental impact. Extend Your System’s Lifespan: Regular maintenance prevents unnecessary wear and tear, helping your system last longer and perform better. Simple Fall Maintenance Tips Even small actions can make a big difference in your HVAC system’s performance. Here are some essential tips: Replace Air Filters Dirty filters reduce airflow, making your system work harder than it needs to. Check your filters monthly and replace them if they appear dirty. A clean filter improves indoor air quality and helps your HVAC system run efficiently. Inspect and Clear Outdoor Units Leaves, dirt, and debris can accumulate around your outdoor unit during the fall. Clear away any obstacles to maintain proper airflow and prevent damage to the system. Check Thermostat Settings Make sure your thermostat is set to the correct temperature and functioning properly. Consider upgrading to a programmable thermostat for precise control and energy savings. Inspect Ductwork for Leaks Leaky ducts can waste energy and reduce comfort. A quick inspection can reveal gaps or holes, which can then be sealed to improve efficiency. Schedule a Professional Tune-Up A trained HVAC technician can perform a thorough inspection, clean components, and ensure everything is operating at peak efficiency. This is especially important before the heating season begins. Additional Benefits of Regular HVAC Maintenance Improved Air Quality: Clean filters and ducts reduce allergens and dust in your home.
