Winter HVAC Maintenance Tips

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 If your thermostat is outdated, consider upgrading to a programmable or smart thermostat for better control and efficiency. 3.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.

As the summer heat in Statesville, NC, continues to rise, the last thing you want is for your air conditioning system to fail when you need it most. At Duncan Heating & Air Conditioning, we understand how critical a functioning AC is to your comfort. To help you stay cool and avoid unexpected breakdowns, we've put together a list of common signs that indicate your AC may need repair.  1. Warm Air Blowing from the Vents If your air conditioner is blowing warm air instead of cool, it's a clear sign that something is wrong. This issue could be due to a refrigerant leak, a malfunctioning compressor, or an issue with the thermostat. Ignoring this problem can lead to more significant issues, so it's best to have a professional take a look as soon as possible. 2. Weak Airflow Weak or insufficient airflow is another sign that your AC is struggling. This could be caused by a clogged air filter, a problem with the blower fan, or even issues within the ductwork. If you notice reduced airflow, your system may not be able to cool your home effectively, leading to higher energy bills and less comfort. 3. Strange Noises Your AC should run relatively quietly, with only the sound of air moving through the vents. If you start hearing unusual noises like grinding, squealing, or banging, it's a sign that something inside the unit is not working correctly. These noises often indicate mechanical issues that, if left unchecked, could result in a complete system failure. 4. Frequent Cycling Air conditioners are designed to cycle on and off at regular intervals to maintain your desired temperature. If your system is constantly turning on and off, it may be short cycling. This behavior could be caused by an oversized unit, a faulty thermostat, or electrical issues. Frequent cycling not only stresses your AC but also leads to higher energy costs. 5. Foul Odors If you notice unpleasant smells coming from your AC, it's a sign that something is amiss. Musty odors often indicate mold or mildew in the ductwork, while burning smells could be a sign of an electrical issue. Either way, it's essential to address these odors promptly to ensure your home remains safe and comfortable. 6. High Humidity Levels In addition to cooling your home, your AC also helps manage indoor humidity levels. If you notice that your home feels more humid than usual, even with the AC running, it could be a sign that your system is not functioning properly. High humidity can lead to discomfort and even mold growth, so it's important to have your AC inspected if you're experiencing this issue. 7. Rising Energy Bills If you've noticed a significant increase in your energy bills without a corresponding increase in usage, your AC may be the culprit. An inefficient system has to work harder to cool your home, leading to higher energy consumption. Regular maintenance can help prevent this, but if your bills are climbing, it's time to have your AC checked for potential problems. Don’t Wait Until It’s Too Late! If you're experiencing any of these signs, don't wait until your AC breaks down in the middle of a heatwave. At Duncan Heating & Air Conditioning, we're here to help keep your home cool and comfortable all summer long. Contact us today to schedule an inspection or repair service and ensure your AC is ready to handle the heat. Call us now at 704-872-2431 or visit our contact page to book your appointment.

At Duncan Heating & Air Conditioning in Statesville, NC, we understand the importance of staying cool during the hot summer months without breaking the bank. Here are some energy-saving tips to help you keep your home comfortable while reducing your energy bills. 1. Use a Programmable Thermostat Investing in a programmable thermostat allows you to set your cooling schedule based on your daily routine. Adjust the temperature to be higher when you’re not home and lower when you are, ensuring you’re not wasting energy cooling an empty house. To learn about some of the smart thermostats we carry and install here at Duncan Heating & Air Conditioning, check out our thermostat product page today. 2. Seal and Insulate Your Home Proper insulation and sealing can significantly reduce the amount of cool air escaping from your home. Check for gaps around windows and doors and use weatherstripping or caulk to seal them. Adding insulation to your attic can also help maintain a consistent indoor temperature. 3. Keep Blinds and Curtains Closed During the day, keep blinds and curtains closed to block out direct sunlight, which can heat your home and make your AC work harder. This simple step can make a noticeable difference in indoor temperature and energy usage. 4. Use Ceiling Fans Ceiling fans can help circulate cool air more efficiently, allowing you to raise your thermostat by a few degrees without sacrificing comfort. Remember to turn off fans when you leave the room, as they are meant to cool people, not spaces. 5. Maintain Your AC Unit Regular maintenance is crucial for keeping your air conditioning system running efficiently. Replace air filters every 1-3 months, clean the evaporator and condenser coils, and check for any obstructions around the outdoor unit. Scheduling annual maintenance with Duncan Heating & Air Conditioning can help prevent issues and ensure optimal performance. 6. Set the Thermostat to a Higher Temperature Every degree you raise your thermostat can save you about 3% on your cooling bill. Aim to set your thermostat to the highest comfortable temperature. The Department of Energy recommends 78°F when you’re home and need cooling. 7. Avoid Using Heat-Generating Appliances During the Day Try to use heat-generating appliances like ovens, stoves, and dryers during the cooler parts of the day, such as early morning or late evening. This can prevent additional heat from accumulating in your home and reduce the strain on your AC unit. 8. Upgrade to Energy-Efficient Equipment If your air conditioner is more than 10-15 years old, consider upgrading to a newer, more energy-efficient model. Look for units with a high SEER (Seasonal Energy Efficiency Ratio) rating, which indicates better energy performance. By following these energy-saving tips, you can keep your home cool and comfortable while minimizing your energy costs.
