The Best HVAC System for North Carolina Homes
Choosing which HVAC system is right for you is a daunting decision. With so many different types and brands of HVAC products on the markets, it is almost impossible to know which best suits your needs. Air Experts is here to break down the functionality of the different types of systems to help you decide which might be right for your Raleigh-Durham area home.
Understanding Cooling and Heating
Homeowners in Raleigh and Durham have several heating and cooling options. We’ve written up a short guide on how each system functions to help you determine which is best for your home:
The way air conditioners and heat pumps cool is actually fairly simple. Warm air always flows towards cold air, never the other way around. Cooling units are based around this principle.
Here is a simple breakdown of the cooling cycle:
- Heat flows, or is transferred, from the air in your house to a refrigerant flowing through evaporator coils
- The refrigerant is pumped outside where the heat from your home is dissipated into the air.
- The cooled refrigerant is then pumped back into your home where the cycle repeats.
All air conditioners use this principle of heat transference. In fact, the refrigerator in your kitchen uses the same method to keep your food fresh.
Furnaces are even simpler than air conditioning. When you burn fuel, you generate heat. Throw a log on a fire or pour lighter fluid on charcoal and you get heat.
In a furnace air is warmed in a heat exchanger either by burning fuel, like gas or propane or by using electric heating elements. The warmed air is then blown through ducts to heat your home.
A significant advantage of a heat pump is that there is only one system handling both cooling and heating. In warmer weather, the heat pump works like an air conditioner. Refrigerant dissipates heat from the house to the outside, sending the cooled refrigerant back inside. In colder weather, the process is reversed. The compressed refrigerant’s heat is transferred to the air inside your home.
Unlike a furnace, heat pumps do not generate heat. They pump and transfer it. No fuel is burned. This can save you money, depending upon local utility rates, making it a very efficient HVAC system.
Mini-split systems are ideal for homes or rooms without ductwork. A ductless mini-split system is essentially a single room heat pump mounted on a wall.
Refrigerant cools the air in the room which is circulated by a blower. Heat exchange then occurs to either heat or cool the room.
The advantage of ductless mini-split systems is that they require no ductwork and are very efficient. Unlike old-fashioned window air conditioners, they do not hang from a window or through a wall.
So Which HVAC System Is Best for You?
The best HVAC system for you will depend on several personal factors:
- Do you prefer combining heating and cooling into one system?
- Do prefer burning fuel in a furnace to generate heat or transferring heat with a heat pump?
- Does your home have ductwork already installed?
- What are the comparable utility rates and consumption for electric powered heat pumps versus fuel burning furnaces?
- How much does efficiency mean to you?
- What is your budget?
Answer these questions, and you will be well on the way towards selecting the HVAC system that’s best for your home.
