Improving Your Air Conditioner

Keep Your Home Cool With A Ground Source Heat Pump

A conventional AC unit should keep your home fairly cool, but it will not necessarily keep your costs down. The cooling costs associated with running an AC unit can make a big dent in your budget; in fact, they are one of the highest costs that a homeowner has to contend with. If you are looking for a way to keep your cooling costs down, you should be willing to pay a little extra money for the right equipment. 

What Is an Air-Source Heat Pump?

An AC unit has two sets of coils. On the inside of your house, you will have a set of of evaporator coils. When the coolant in the system hits these coils, they will vaporize and absorb heat from their environment. The super-heated coolant then cycles out to your condenser unit, which forces relatively cool air over the coils to condense the vapor back to a liquid. A heat pump allows you to reverse the function of your coils so that they absorb heat from the outside air and vent it into your house. 

What Are the Weaknesses of a Air-Source Heat Pump?

An air-source heat pump is susceptible to the varying temperatures of the outside air. As long as air temperatures are moderate, the heat pump will have good efficiency, but the hotter or colder it gets, the less efficient it will be. At best, an air-source heat pump will be 250% efficient. This might sound impressive, but you can double this efficiency with a ground-source heat pump.

What Is a Ground-Source Heat Pump?

To sidestep the variable nature of outside air, you can use a specially designed set of condenser coils to tap into the more moderate temperature of the earth. In that the temperature of the earth ten feet below the surface will stay between 50–60 degrees year round, you don't have to worry about extreme temperatures undermining your system efficiency. Because of this consistency, you can achieve efficiency ratings of up to 600%. If you connect your heat pump to a set of solar panels or a wind turbine, you can take your heating and cooling entirely off of the grid. 

Paying too much to heat and cool your home can leave your budget strained. Paying for a ground-source heat pump may not be something you think you can financially handle, but if you save more money on heating and cooling your home than what you pay in financing, the expense will be worth it.
