Alternative Heating and Cooling Systems

Geothermal heating and coolingMost people in the area use traditional centralized heating and air conditioning systems to keep their homes comfortable. A furnace generates hot air and an AC cold air—both in a centralized location—which is then blown through the ducts in the house with a fan. They’re inexpensive, comparatively simple, and easy to operate, which is what makes them so popular.

They’re not the only means of keeping a home comfortable, however, and in some cases, an alternative system might work better. Older houses may not be able to support the ducts necessary for a centralized system, while larger homes may struggle to feel as warm or as cool as they should with a centralized system. If your home can’t support a centralized system or has experienced recurring problems with its effectiveness, you might want to consider other options. We’ve laid out a few below for you to consider.

Heat Pumps

Heat pumps use the principles of air conditioning–circulating refrigerant through a series of valves and coils that first release hot air and then cool the air for distribution into the home–to serve as a heater as well as an air conditioner. They work well for homes that don’t have a structural problem with centralized HVAC systems but could use a little help with monthly heating costs.

Because heat pumps use refrigerant to generate heat, they don’t need to spend as much fuel to warm the home, and they work especially well in climates like ours that have mild winters. In some cases, they need help on the coldest nights, which is why dual-fuel systems exist: adding a small furnace to the heat pump in order to provide that extra bit of heating power.

Ductless Mini Split Systems

Ductless systems adopt a decentralized approach to heating and cooling. Instead of a single unit covering the entire house, the system installs multiple smaller units throughout the house, each one tasked with covering a single room or section. This allows comprehensive heating and air conditioning without relying on ducts.

It also provides precise control over the temperature in each section of the house. Not only can you raise and lower the temperature in each section independently of the rest of the house–letting individual family members set the temperature to their taste–but it lets you turn off the heat or cooling to parts of the home you aren’t using while still running the HVAC system in parts of the home you are.

Geothermal Heating and Cooling

Geothermal systems use tubes full of liquid buried under the earth to provide heating and cooling power. Once you dig below about ten feet or so, the temperature of the earth remains in a stable range no matter what the weather topside is. Geothermal systems take advantage of this. The set-up cost is high since the tubes need to be buried beneath the property, but over time, they can save a household a considerable amount of money.
