    • What two types of HVAC system designs are there?

      While there are numerous types of HVAC systems available to install in your home, the designs typically fall into one of two categories: ductless and ducted. But what exactly does this mean? Here is a closer look at these two different types of HVAC systems in more detail below:

      Ducted HVAC System:

      A ducted HVAC system is a heating, ventilation, and air conditioning system that uses a network of air ducts to circulate conditioned air throughout your home. The ducts are typically located in the walls, floors, or ceilings and are used to transport the air from the central unit to the different rooms all at once.

      Ductless HVAC System:

      A ductless HVAC system, on the other hand, is a system that does not use ducts to distribute air. Instead, it uses one or more small indoor units that are installed in the room or area where air conditioning or heating is needed. These indoor units are connected to an outdoor unit by a small tube that contains refrigerant lines, power cables, and a drain hose, depending on what type of HVAC unit you have installed in your home.

      Ductless systems are often considered to be more efficient than ducted HVAC systems because they do not lose conditioned air through the ducts. They are also more flexible because they can be installed in a variety of locations and can be controlled individually, allowing you to adjust the temperature in different rooms or areas of the building separately. However, there are numerous types of high-quality HVAC systems that are also duct systems that will help you heat or cool your home efficiently, depending on your needs.

      At the end of the day, it is up to homeowners which one they would like to install in their homes, depending on their individual needs and preferences. Luckily, at Dunn Heating, we have a wide selection of ducted and ductless HVAC systems for homeowners to choose from. With the help of our experienced and knowledgeable HVAC technician team, you will be able to customize your experience and choose a unit that best fits your needs so you can maximize your home comfort throughout the entire year.

      Are you thinking of installing a new HVAC system in your home? If the answer is yes, Dunn Heating is ready to help! Dunn Heating is available 24 hours a day, seven days a week. Our certified HVAC technicians will never charge a service fee if homeowners necessitate our services after business hours, on weekends, or on holidays.

    • What is the primary function of HVAC?

      HVAC stands for heating, ventilation, and air conditioning. These systems are designed to provide heating, cooling, and indoor air quality control for buildings. The primary function of HVAC systems is to provide a comfortable indoor environment by maintaining a constant temperature, humidity level, and air quality that you and your family can enjoy all year round, regardless of what the outdoor temperature is like.

      HVAC systems are essential to any building or residential home as they help create a comfortable and healthy indoor environment for occupants. Proper maintenance and regular servicing of HVAC systems are necessary to ensure that they operate efficiently and effectively. With that being said, there are numerous types of heating, cooling, and ventilation systems you may not be aware of. Therefore, here is a closer look at some of these HVAC systems in more detail below:

      Heating Systems:

      • Furnaces: Furnaces burn fuels, such as natural gas, propane, or oil, to generate heat. The heat is then distributed through your home using a system of ducts and vents.
      • Boilers: Boilers use gas, oil, or electricity to heat water, which is then distributed through your home using your home’s air ducts. 
      • Heat pumps: Heat pumps use electricity to transfer heat from the outdoor air or ground into the building. They can also remove heat from your home to cool it during the summertime. 

      Cooling Systems:

      • Air conditioners: Air conditioners use refrigerants to transfer heat from indoor to outdoor air. There are a few types of air conditioning units you can install in your home, such as central AC units, ductless AC units, and split AC units. 

      Ventilation Systems

      • Humidifiers: Humidifiers ensure the moisture levels in your home remain safe to ensure the air you breathe does not cause symptoms such as sore throats, itchy skin, dry eyes, and more.
      • UV Air Purifiers: UV air purifiers use ultraviolet lights to eliminate harmful airborne pollutants such as chemicals, bacteria, viruses, and more that can cause prolonged sickness and be harmful to your overall health.

      As you can see, HVAC units are an important feature in any home. And at Dunn Heating, there are several types of HVAC systems homeowners can have installed in their Kitchener-Waterloo homes. As such, if you are ready to work with the team at Dunn Heating for any repairs, maintenance, or installation projects you may need to be completed by a professional company, our certified technicians are waiting to help you at any time!

    • What component of HVAC is the most crucial?

      All components of an HVAC system are essential for its proper functioning. However, some elements are considered more critical than others, depending on the specific needs and requirements of the building or space being heated or cooled. Some of the most vital components of an HVAC system include the following:

      1. The thermostat: The thermostat is the control center of the HVAC system. It regulates the temperature and airflow in the building or space by turning the heating and cooling equipment on and off as needed.
      2. The furnace, heat pump, or boiler: The furnace, heat pump, or boiler is the central heating component of the HVAC system. It generates heat by burning fuel or using electricity and distributes the heat throughout the building or space via the air ducts or radiators.
      3. The air conditioner or heat pump: The air conditioner or heat pump is the primary cooling component of the HVAC system. It removes heat from the air and distributes the cooled air throughout the building or space via the air ducts.
      4. The ventilation system: This includes humidifiers and UV air purifiers which are responsible for circulating the air in your home and ensuring it is free of any harmful particles, chemicals, bacteria, and viruses that can lead to illness.
      5. The air ducts: The air ducts are the network of tubes or channels that transport the heated or cooled air throughout your home. They are usually located in the walls, floors, or ceilings and play a critical role in the overall efficiency of the HVAC system.

    • What differentiates HVAC from AC?

      HVAC stands for heating, ventilation, and air conditioning. It is a system designed to provide heating, ventilation, and cooling solutions to a home throughout the year, regardless of what the weather is like outside with the touch of a button. An HVAC system is typically made up of a central unit responsible for heating and cooling the air, a network of air ducts used to distribute the air throughout the building, and a system of controls that allow you to regulate the temperature and airflow in the space.

      AC, on the other hand, stands for air conditioning. You can think of air conditioning as a smaller portion of an entire HVAC system. It refers specifically to cooling the air in your home. There are several types of air conditioning systems available for you to install in your home, and choosing which unit works best for you will depend on your personal cooling preferences, along with several other factors that will be taken into account during your initial consultation appointment with professional HVAC Services in Kitchener-Waterloo.

      At Dunn Heating, we are pleased to offer homeowners an extensive selection of air conditioning units that we can tailor to their unique needs. Our team of certified HVAC technicians will work with you one-on-one to help you determine which unit will help you maximize your home comfort throughout the year!

    • Is HVAC electric or gas?

      HVAC systems can be powered by electricity, gas, or a combination. The type of fuel used to power an HVAC system depends on the homeowner’s specific needs and preferences, the kind of home that needs to be heated or cooled, and the availability of different fuel sources in the area.

      Electric HVAC systems are powered by electricity and use an electric furnace or heat pump to generate heat. They are often used in homes with reliable electricity but no natural gas or other fuel. Electric HVAC systems are generally considered more efficient. They have a lower environmental impact than gas-powered systems. Still, they can be more expensive to operate due to higher electricity costs.

      Gas HVAC systems are powered by natural gas, propane, or other fossil fuels and use a gas furnace or boiler to generate heat. They are often used in homes with a dependable supply of natural gas or other fuel sources. Still, they can also be used in areas where electricity is the primary fuel source. Gas HVAC systems are generally less expensive to operate than electric systems. Still, they can have a higher environmental impact due to the emissions associated with burning fossil fuels.

      At Dunn Heating, we have a selection of gas and electric HVAC systems for homeowners to choose from. Our team of dedicated HVAC technicians can help guide you through the process of choosing an HVAC unit that best matches your unique needs and home.

      Dunn Heating is available 7 days a week, twenty-four hours a day. Our certified HVAC technicians will never charge a service fee if homeowners need our services after business hours, on weekends, or on holidays. Besides that, when buying a brand-new HVAC system from the Dunn Heating team in Kitchener-Waterloo, property owners can choose from a diverse selection of financing options. This way, you can upgrade the HVAC system in your residence without any upfront costs!
