HVAC systems, as per the United States Department of Energy, account for an estimated 48% of household energy consumption. The type of HVAC system you purchase can make a huge difference in keeping those Bay Area utility bills down. You should choose an HVAC system based on the climate in your area, home construction, and size. These are a few ideal HVAC systems for home purposes.
1. Standard AC & Furnace Split System
These systems are also called forced air systems and have been around for a long time. Blower fan in the furnace is responsible for pulling in unconditioned air and pushing out treated air through the duct system. Separate furnace in these systems is usually natural gas powered or propane powered.
The system is popular in areas with mild climate that don’t require central air conditioning. Newly installed units can be as much as 90% energy efficient. However, a downside to the system is that the ductwork may develop dangerous leaks that results in carbon monoxide poisoning.
2. Standard Heat Pump and Air Handler Split System
This is another popular HVAC system for households. The heat pump in this setup provides air conditioning and heating. Refrigerant is circulated through the system by a compressor. Air is pushed through the system using an indoor handler with a blower. It is then circulated within all living spaces of the residence to maintain a comfortable climate. Low operating and equipment costs make standard heat pumps highly popular within the country. However, they require ductwork and can spread pathogens and allergens throughout the home.
3. Boiler with Radiant Heat System & AC
Radiant boilers heat water to very high temperatures and push them through special pipes installed in the flooring. This warms up the house completely. You would need a separate air conditioner for the summer months. Radiant heating systems can use natural gas, electric, and propane to heat water.
Radiantly heated air as per experts is the most comfortable type of heated air in a household. It is neither too humid nor too dry. However, boilers take longer than standard furnace systems to heat a house. You would also need to install special radiant floor pipes which can be costly.
4. Mini-Split Heat Pump System
These systems are similar to standard heat pump systems. However, they don’t involve just one system. Instead, there are several different units set up around the house in zones. You may need anywhere from 2 – 8 units depending on the size of your house.
This system is rapidly growing in popularity because of increased efficiency and lowered cost. You don’t need any ductwork with these units making them a great choice for people with allergies. However, the initial setup cost may be higher than traditional systems.
5. Geothermal Heat Pump System
Geothermal heat pump system is another poignant option. It relies on underground pipes to circulate water that gets cooled in summer and warmed in winters. It is a highly energy efficient system since it uses the natural temperature of the soil for climate control processes. These systems can last for as long as 25 years but may incur an expensive initial installation. Repair costs are also higher in these systems.
