Today's residential HVAC (heating, ventilation, and air conditioning) systems use different methods and techniques for channeling heat outside of the home or to bring the warm air in. Certain systems such as air conditioning absorb heat from within the home using a refrigerant gas and then transfer it outdoors. Other systems, such as furnaces, typically use electricity or natural gas to create their own heat for warming up your home's interior. When you shop for the best residential systems, it is important that you focus on energy-saving systems.
Natural Gas Systems
The first thing you need to remember about natural gas operated HVAC systems is that they create their own heat through the burning of natural gas. In those cases where natural gas is not available, such as rural areas, propane is used instead. An affordable gas furnace is the best option when you live in climates that are too cold for having a heating pump to warm your home. Although natural gas burns less efficiently than other types of fuels, it is considerably less expensive than others. Additionally, there is less maintenance than what you would experience with the more traditional oil furnace.
These systems heat a home's interior through the use of infrared technology with the two most common types being hot water piping and insulated wire systems. Hot water piping systems are commonly installed when the floor of the home is. Conversely, insulated wire systems are considerably more flexible. If you are an allergy sufferer, this is the most recommended system as radiant heating does not make the air circulate and move around the home. There are also water-based varieties which are more cost-effective.
By far, these systems are the most energy-efficient as they do not create heat. Instead, they circulate it around the home. Using a heat pump is the best transference method although air conditioning will perform that function automatically. Heat pumps function in one of two ways. They cool the home by pulling warm air outside and they warm the home by drawing warmed air inside. The two disadvantages of heat pumps are that they do not work efficiently enough in cold weather climates and they have a high initial cost.
HVAC systems are designed and developed to accommodate different sized commercial and residential structures and are rated to facilitate the amount of interior cubic feet. If you install an HVAC system that is too large for the structure, it will start and stop continually. In the long run, this will result in costly utility bills. On the other hand, if you install a system that is too small for your home or office, it will run continually. This will cost you a lot more due to additional maintenance fees and inflated utility bills.
New HVAC Technologies To Keep Homes Cooler
On a closing note, there are several newer energy-efficient HVAC technologies that were recently introduced in the past decade that help cool homes more cost-effectively. These include:
- Desiccant Enhanced Evaporative Air Conditioner or DEVAP systems
- Heat recovery systems
- Home automation
- Nest learning thermostats
- Passive dehumidification
- Residential zoning units
There is a considerable amount of information available online regarding these technologies. It is important to remember that regardless of the system or technology that you select for cooling and heating your home, all of them will work more cost-effectively and efficiently by performing regular preventative maintenance. By ensuring that a system is working to its fullest potential, it will enable you to conserve energy and realize significant savings on the maintenance and operation of them throughout the year.
