As fall settles in, temperatures begin to cool, and it's time to prepare your HVAC system for the demands of the upcoming winter. Unfortunately, this seasonal transition can often bring about common HVAC issues that may affect comfort and efficiency in your home. At Duncan Heating & Air Conditioning, we're here to help you recognize and prevent some of these issues, so your home remains cozy all season long. 1. Clogged or Dirty Filters Issue: Dust, pollen, and other particles accumulate on filters over time, which can restrict airflow and reduce your system’s efficiency. Clogged filters also force your HVAC system to work harder, leading to increased energy bills and even potential system breakdowns. Solution: Check your filters monthly and replace them at least every three months. Fall is an ideal time for a filter change as you prepare to use your heating system more frequently. 2. Thermostat Malfunctions Issue: A malfunctioning thermostat can lead to uneven temperatures, causing certain rooms to be too hot or too cold. Inaccurate temperature readings can also cause the system to cycle on and off more frequently, increasing wear and tear. Solution: Replace batteries in your thermostat and double-check the settings. If your thermostat is outdated, consider upgrading to a programmable or smart thermostat for better control and efficiency. 3. Ignition or Pilot Light Problems Issue: Older heating systems with pilot lights may experience ignition issues, especially when they haven’t been in use during warmer months. Faulty ignition can result from issues like a dirty flame sensor, gas supply problems, or a worn-out pilot light. Solution: Schedule an inspection to ensure your ignition system and pilot light are working correctly. A professional tune-up from Duncan Heating & Air Conditioning can help prevent ignition issues before they escalate. 4. Blocked or Leaky Ductwork Issue: Ductwork issues can reduce airflow, cause your system to overwork, and lead to uneven heating in your home. Leaky ducts can also pull in dust and contaminants, affecting indoor air quality. Solution: Check for visible duct leaks and ensure vents and registers are clear of debris. Our team can also conduct a thorough inspection and seal any leaks in your ductwork for improved efficiency. 5. Unusual Noises Issue: Banging, squealing, or rattling sounds are often signs of mechanical issues, such as loose parts or problems with the blower motor. Ignoring these sounds can lead to more significant damage. Solution: Don’t ignore unusual noises. Schedule a maintenance check to diagnose and resolve these issues before they cause major damage. 6. Decreased Energy Efficiency Issue: Older or poorly maintained HVAC systems tend to be less energy-efficient, leading to higher energy bills, especially when temperatures drop. Solution: Invest in seasonal HVAC maintenance to keep your system running smoothly. Regular tune-ups by our technicians at Duncan Heating & Air Conditioning can boost efficiency and help you save on energy costs.

As the cooler weather approaches in Statesville, NC, it’s essential to make sure your HVAC system is ready to keep your home comfortable throughout the fall and winter months. At Duncan Heating & Air Conditioning, we understand the importance of seasonal HVAC maintenance to ensure reliable performance, energy efficiency, and safety. With a little preparation, you can avoid costly repairs, improve indoor air quality, and enjoy peace of mind knowing your system is ready to handle the chill. Here are our top fall maintenance tips to get your HVAC system ready for the season ahead. 1. Schedule a Professional HVAC Tune-Up The best way to ensure your heating system is operating at peak efficiency is to schedule a professional tune-up. A licensed HVAC technician from Duncan Heating & Air Conditioning will inspect and clean critical components of your system, including the furnace, heat pump, and air handler. This thorough check-up helps identify any potential issues before they turn into major problems, ensuring your system is ready for the colder months. Regular tune-ups also help improve energy efficiency, lowering your heating bills throughout the season. 2. Change Your Air Filter One of the simplest yet most effective maintenance tasks you can do is replace your HVAC system’s air filter. A clean air filter ensures proper airflow and prevents dust, dirt, and allergens from circulating throughout your home. During fall, when allergens like mold spores and ragweed are common, a fresh filter can help improve indoor air quality and keep your system running efficiently. We recommend checking your air filter monthly and replacing it at least every 90 days—or more often if you have pets or allergies. 3. Clean and Inspect Vents and Ductwork Blocked or dirty air vents and ductwork can reduce the efficiency of your HVAC system, leading to uneven heating and higher energy bills. Before the colder weather sets in, take the time to vacuum out air vents and ensure they’re free of dust and debris. Additionally, consider scheduling a professional duct cleaning service to remove built-up dirt, mold, and allergens from your ductwork. Clean ducts not only improve airflow but also help maintain better indoor air quality. 4. Test Your Thermostat Your thermostat is the control center for your heating system, so it’s important to make sure it’s functioning correctly. Test your thermostat by turning on the heat and checking that the system responds promptly. If you’re still using a manual thermostat, now is a great time to upgrade to a programmable or smart thermostat, which can help you better manage your energy usage and save on heating costs. Smart thermostats allow you to control your home’s temperature remotely, ensuring comfort while maximizing efficiency. 5. Check for Air Leaks Cold air can seep into your home through gaps and cracks around windows, doors, and other areas. These air leaks can cause your HVAC system to work harder to maintain a comfortable indoor temperature, driving up your energy bills. Seal any gaps with weatherstripping or caulk to keep warm air inside and reduce the strain on your heating system. Proper insulation and airtight seals can make a noticeable difference in both comfort and energy savings. 6. Clear the Area Around Your Outdoor Unit If you have a heat pump or another outdoor unit, be sure to clear away any leaves, branches, or debris that may have accumulated over the summer. Keeping the area around your unit free of obstructions ensures proper airflow and allows the system to operate efficiently. It’s also a good idea to check that the unit is level and inspect it for any signs of damage. If you notice anything unusual, contact Duncan Heating & Air Conditioning for a professional inspection. 7. Test Your Carbon Monoxide Detectors As you prepare your home for the cooler months, don’t forget to check your carbon monoxide detectors. Gas-powered furnaces can produce carbon monoxide if there’s a malfunction, and having a working detector is critical for your safety. Test your detectors and replace the batteries if needed to ensure they’re fully operational throughout the heating season.
