General HVAC Questions

  • What services does Wellman Heating & Air provide?

    We offer a comprehensive range of HVAC services, including installation, repair, and maintenance for air conditioning systems, furnaces, water heaters, and boilers. We also provide solutions for improving indoor air quality and offer flexible financing options.

  • How often should I have my HVAC system serviced?

    We recommend annual maintenance for both your heating and cooling systems. Ideally, your air conditioning system should be serviced in the spring before the cooling season, and your furnace or boiler in the fall before the heating season. Regular tune-ups help ensure efficiency, prevent breakdowns, and extend the lifespan of your equipment.

  • What are the signs that my HVAC system needs repair?

    Common signs include unusual noises (banging, hissing, grinding), strange odors (burning, musty), inconsistent temperatures, increased energy bills, frequent cycling on and off, or no heating/cooling at all. If you notice any of these, it's best to call a professional.

  • How long do HVAC systems typically last?

    The lifespan of HVAC systems varies depending on the type of unit, how well it's maintained, and its usage.


    • Air conditioners: 10-15 years
    • Furnaces: 15-20 years
    • Boilers: 15-20 years
    • Traditional water heaters: 10-15 years
    • Tankless water heaters: 20+ years

    Regular maintenance can significantly extend these lifespans.

  • Do you offer emergency services or after-hours appointments?

    es, we understand that HVAC emergencies can happen at any time. Please contact us for details on our emergency and after-hours service availability.

  • Do you offer financing options for new installations or major repairs?

    Yes, we offer flexible financing plans to make our services accessible and ensure you can get the comfort you deserve without financial stress. Contact us for more information on available options.

Air Conditioning Questions

  • Why is my air conditioner not cooling effectively?

    This could be due to several issues, including a dirty air filter, low refrigerant levels, a malfunctioning thermostat, or a frozen evaporator coil. Our technicians can diagnose the exact problem and provide the necessary repairs.

  • How often should I change my air filter?

    We generally recommend changing your air filter every 1-3 months, especially during peak cooling or heating seasons. If you have pets, allergies, or live in a dusty environment, you may need to change it more frequently.

  • What is a SEER rating?

    SEER stands for Seasonal Energy Efficiency Ratio. It measures the cooling efficiency of an air conditioner. A higher SEER rating indicates a more energy-efficient unit, which can lead to lower energy bills.

  • Why is my AC unit freezing up?

    A frozen AC unit often indicates reduced airflow (due to a dirty filter or blocked vents) or low refrigerant levels. If your unit is freezing, turn it off and call a professional to prevent further damage.

Furnace & Furnace Repair Questions

  • My furnace isn't producing heat. What should I check first?

    First, ensure your thermostat is set to "heat" and the temperature is higher than the current room temperature. Check if the furnace's power switch is on and if the circuit breaker has tripped. Also, inspect your air filter to ensure it's not clogged. If these simple checks don't resolve the issue, it's time to call us.

  • How often should I replace my furnace filter?

    Similar to AC filters, furnace filters should typically be replaced every 1-3 months. A dirty filter can restrict airflow, reduce efficiency, and even damage your furnace.

  • What's the typical lifespan of a furnace?

    With proper maintenance, a gas furnace can last 15-20 years or more. Electric furnaces can sometimes last even longer.

  • Why is my furnace making strange noises?

    Banging, whistling, squealing, or grinding noises from your furnace can indicate various issues, such as a loose belt, a malfunctioning motor, or issues with the blower fan. It's best to have these noises checked by a professional to prevent more serious damage.

Water Heater Replacement Questions

  • How do I know if I need a new water heater?

    Signs that your water heater may need replacement include:


    • Lack of hot water or inconsistent temperatures.
    • Rust-colored or cloudy water.
    • Leaking from the tank.
    • Strange noises (rumbling, popping, whining) coming from the tank.
    • The water heater is more than 10-15 years old.
  • What are the benefits of upgrading to a tankless water heater?

    Tankless water heaters provide on-demand hot water, meaning you'll never run out. They are also significantly more energy-efficient than traditional tank models, leading to lower energy bills. Additionally, they have a longer lifespan and save space.


  • What size water heater do I need for my home?

    The appropriate size depends on your household's hot water demand, including the number of occupants, bathrooms, and hot water appliances. We can help you determine the ideal size for your specific needs to ensure you have an adequate and efficient hot water supply.

  • What happens to my old water heater after replacement?

    Wellman Heating & Air will typically handle the proper disposal and removal of your old water heater as part of our replacement service.

Boiler Questions

  • How does a boiler heating system work?

    Boilers heat water that is then circulated through pipes to radiators, baseboard heaters, or radiant floor systems to warm your home. Some boilers also produce steam for heating.


  • What are common signs that my boiler needs repair?

    Look out for:


    • No heat or insufficient heat.
    • Unusual noises (gurgling, banging, whistling).
    • Leaking water around the boiler.
    • Low boiler pressure.
    • Pilot light repeatedly going out (for older models).
    • Radiators that are cold or only partially warm.
  • How often should my boiler be serviced?

    Similar to furnaces, boilers should receive annual professional servicing, ideally in the fall, to ensure safe and efficient operation throughout the heating season.

  • What is "kettling" and why is my boiler making that noise?

    "Kettling" is a whistling or rumbling sound from your boiler, similar to a boiling kettle. It's often caused by a buildup of limescale or sludge inside the heat exchanger, restricting water flow. This can reduce efficiency and put strain on the system, so it's important to have it addressed by a professional.
