Before you can choose an HVAC system for your home, you need to understand what makes up an HVAC system. An HVAC system consists of three basic components: an HVAC unit, ductwork, and an air source. The HVAC unit is the part of the system that actually produces and distributes the conditioned air throughout your home. The ductwork is a network of metal or plastic pipes that carry the conditioned air from the HVAC unit to different rooms in your home. The air source is the source of conditioned air in your home (like the outdoors).
Once you understand these basics, you can start to narrow down your choices for HVAC systems. Here are some questions to ask yourself as you begin your search for the best HVAC system for your home:
How many people live in the home?
What size is the home?
What type of heating and cooling do you want to use in the home?
What is your climate zone?
A central air conditioning system is the most common type of HVAC system. A central air conditioning system consists of a central air handler, a cooling/heating pump, ductwork, and an air filter. A central air conditioning system is controlled by a thermostat.The cooling/heating pump is powered by the central air handler, which is controlled by the thermostat. The air filter helps clean the air before it is sent through the ductwork.The ductwork is usually located in the attic of your home.Central air conditioning systems are most commonly used in large, single-family homes and apartment buildings.
A heat-pump system is the most energy-efficient HVAC system. A heat-pump system is essentially an air conditioner and a heat-pump working in tandem. The heat-pump is responsible for cooling your home in the summer, while the air conditioner is responsible for cooling your home in the winter.A heat-pump system is often used in smaller homes or apartments. In most cases, a heat-pump system is more efficient than a central air conditioning system.
A ductless heating system is a standalone heating system that does not require ductwork. These systems are often used in small, secondary homes or in apartment buildings.A ductless heating system consists of a heat source (usually gas or electric), a fan, a heat exchanger, and a fan control. The fan controls the flow of air through the system, and the heat exchanger heats the air.
A ductless cooling system is similar to a ductless heating system — it does not require ductwork and is installed directly in the home.A ductless cooling system consists of a cooling source (usually a compressor), a heat exchanger, and a fan control. The cooling source is usually powered by electricity. The heat exchanger cools the air.
A room air conditioner is a small, standalone cooling system that is installed in a single room. Room air conditioners are most commonly used in bedrooms and small living rooms.A room air conditioner is a great option for homes with minimal cooling needs. Room air conditioners are much less expensive than central air conditioning systems and are often more efficient, too.
The best HVAC system for your home will depend on several factors, including the size of your home, the number of people living there, and your climate zone. When shopping for an HVAC system, consider your budget, the climate in your area, and how you plan to use your home. Once you’ve found the right system for your home, it will be an important part of your daily life for years to come. Now that you know more about HVAC systems, you can make an informed decision when purchasing a new system for your home.
