Looking to replace your heat pump?

A new heat pump can be a game-changer for your comfort and budget. North Carolina experiences both hot summers and chilly winters, and a reliable heat pump is essential for maintaining ideal indoor temperatures year-round. A new heat pump offers enhanced energy efficiency, helping you save on heating and cooling costs. It provides consistent and reliable comfort, ensuring you stay cozy during winter's chill and cool in the summer heat. Moreover, newer models often come with advanced features, such as smart thermostats and eco-friendly refrigerants, contributing to both convenience and environmental responsibility. So, if you're seeking optimal comfort, savings, and peace of mind, consider investing in a new heat pump for your North Carolina home.

Let's service that furnace.

When servicing a gas furnace, we follow a comprehensive checklist to ensure the system's safety and optimal performance. They typically begin by inspecting the heat exchanger for cracks or corrosion, as any damage could lead to dangerous gas leaks. Next, they check and clean the burners, igniter, and flame sensor to ensure efficient combustion and ignition. Air filters are cleaned or replaced to maintain good indoor air quality and system efficiency. The thermostat is calibrated for accurate temperature readings, and electrical connections are inspected for safety. Contractors also assess the blower motor and fan for proper operation and lubricate moving parts as needed. Finally, they check gas pressure, exhaust venting, and carbon monoxide levels to ensure safe operation. Regular maintenance by HVAC professionals not only keeps gas furnaces running efficiently but also prevents potential hazards associated with gas heating systems.

Maintain your heat pump.

Receiving heat pump maintenance in North Carolina is of paramount importance due to the state's variable climate. In NC, we experience hot and humid summers as well as chilly winters, making heat pumps a common choice for year-round comfort. Regular maintenance ensures that your heat pump operates efficiently, helping you stay cool during sweltering summers and warm in the winter cold. It can save you money on energy bills and prevent inconvenient breakdowns during extreme weather conditions. North Carolina's climate also means that pollen and allergens are a concern, so maintenance helps maintain good indoor air quality. With professional heat pump maintenance in NC, you not only extend the life of your system but also enjoy reliable comfort and peace of mind, knowing that your HVAC system is well-prepared for the region's ever-changing weather.

  • Common HVAC Questions

    Here are some of the most frequently asked heating and air conditioning questions we receive from our customers. Click below to learn the answers to some of our most FAQs here at Duncan Heating & Air Conditioning:

    Schedule Service
    • How often should I service my HVAC system?

      To keep your HVAC system running in tip-top shape, we recommend a maintenance appointment twice a year (once for heat, once for air conditioning). This way, an Oliver technician can check your filters, coils, wiring, housing, motor, and more to make sure you’re getting the most out of your system.

    • How do I know if I need a new HVAC system?

      If your HVAC system requires constant repairs, is 15 years or older, or can’t heat or cool your home properly, we recommend you replace it. When an HVAC system ages, it doesn’t operate as efficiently and could actually end up costing you more money than it should.

    • When should I replace air filters?

      The air filters are one of the most important components of an HVAC. They catch all the airborne particles that you don’t want floating around your home and in your lungs. Once they become full or clogged, your indoor air quality becomes compromised and the lack of airflow can lead to system breakdowns. It is best to replace your air filters about every three months and more often if you live with a smoker or someone with allergies or asthma.

    • What size HVAC unit is right for my home?

      HVACs are not one-size-fits-all. If your unit is too big for the home, it will pump out more air than needed, causing higher bills and an increase in condensation which can lead to mold and algae growth. If the unit is too small, it will become overworked and your home will see uneven temperatures. Your HVAC professionals will help you determine the correct size unit for your home as you begin the process of a new installation.

    • What is a heat pump?

      A heat pump is a part of the heating and cooling system which is installed outdoors and pulls in air to heat or cool your home. They are more eco-friendly than a furnace as they do not burn fossil fuels, require minimal maintenance, are long lasting, and can both heat and cool your home.

    • Why are maintenance appointments important?

      We wouldn’t say maintenance appointments are important. We’d say they are ESSENTIAL! By scheduling these visits from your technician, you’re setting your HVAC up for a successful season of heating or cooling. The technician will clean your unit and replace your air filter, improving your indoor air quality. They will also be able to spot the warning signs of a potential future breakdown and solve them before they cost you down the road.

    • What is HVAC?

      HVAC, which stands for Heating, Ventilation, and Air Conditioning, is an all-encompassing term when it comes to talking about your heating and cooling system in its entirety. While the world of HVAC might seem complicated, it doesn’t have to be confusing for homeowners. Give the Duncan Heating & Air Conditioning team a call for any HVAC service needs you may have!


    • What is the purpose of an HVAC system?

      An HVAC system serves various purposes in your home including maintaining a comfortable indoor environment, preventing moisture and mold growth, eliminating allergens and pollutants, providing fresh air ventilation, and more!

    As the vibrant colors of spring begin to bloom in Statesville, NC, it's time to transition your HVAC system from heating to cooling mode.

Clean Outdoor Unit Check the outdoor condenser unit for any debris, such as leaves, twigs, or grass clippings, that may have accumulated during the winter months. Clear away any obstructions and gently clean the unit with a hose to ensure optimal airflow and efficient operation. *4. Adjust Thermostat Settings Update your thermostat settings to reflect the changing weather. As temperatures rise, you can gradually adjust your thermostat settings to optimize comfort and energy efficiency. Consider using programmable or smart thermostats for added convenience and savings. *5. Test System Operation: Finally, test your HVAC system to ensure it's functioning correctly before the hot weather arrives. Turn on your air conditioning system and check for any unusual sounds, odors, or performance issues. If you notice any issues, contact our team for prompt inspection and repairs. By following these tips, you can ensure that your HVAC system is ready to tackle the warmer weather and keep you comfortable throughout the spring season in Statesville, NC.

    As temperatures drop in Mooresville, NC, your HVAC system becomes even more crucial for maintaining a comfortable indoor environment during the winter months. However, the cold weather can put additional strain on your heating system, leading to potential breakdowns or inefficiencies if not properly maintained. Here are some essential winter HVAC maintenance tips from the Duncan Heating & Air Conditioning team to keep your system running smoothly and efficiently. Change Air Filters Regularly Dirty air filters can restrict airflow, reduce indoor air quality, and strain your heating system. Make sure to replace or clean your air filters every one to three months to ensure proper airflow and efficient operation. Inspect and Clean Vents and Registers Ensure that all vents and registers are free from obstructions such as furniture, rugs, or curtains. Blocked vents can disrupt airflow, causing uneven heating and putting unnecessary strain on your HVAC system. Schedule a Professional Inspection Consider scheduling a professional HVAC inspection before the peak of winter. Our experienced technicians can identify any potential issues or inefficiencies in your heating system and address them promptly, ensuring reliable performance throughout the season. Check for Air Leaks Inspect doors, windows, and other areas where air leaks may occur. Seal any gaps or cracks with weatherstripping or caulking to prevent warm air from escaping and cold air from entering your home, reducing the workload on your heating system. Program Your Thermostat Use a programmable thermostat to adjust the temperature settings according to your schedule. Lowering the temperature when you're asleep or away from home can help save energy and reduce heating costs without sacrificing comfort. To learn about some of the smart and programmable thermostats we carry and install here at Duncan Heating & Air Conditioning, check out our thermostat product page today! By following these winter HVAC maintenance tips and partnering with Duncan Heating & Air Conditioning, you can ensure that your heating system remains efficient, reliable, and ready to keep you warm during the coldest months in Mooresville, NC.
