Whether you are interested in replacing your existing gas furnace with a more efficient model, or are looking at moving to gas heat for the first time, we can help! Value is the key when looking at what kind of furnace you want and many options are available. Chances are your new furnace will get more use than all the cars you will ever drive put together, so it is important to choose one that will last and be as efficient as possible.

UNDERSTANDING GAS FURNACE OPTIONS

Efficiency:

Gas furnaces are usually separated into two categories: 80+ and 90+, which refers to the efficiency of the equipment. 80+ furnaces put about 80% of the heat into your home and the other 20% goes up the chimney. 90+ furnaces put 90%-98% of the heat into your home and the small percent left goes up the chimney. Most 90+ furnaces are actually 95% or more efficient now, largely because that is the efficiency required for the 2009-2010 tax credit. 95% furnaces have become more popular than 80% furnaces, especially with the tax credit in place. There is also legislation in the works to ban 80% efficient furnaces within the next five years.

Single Stage vs. Two Stage:

Single Stage furnaces are either on or off, with no adjustment possible. A Two Stage furnace can operate on high or low, depending on the heating needs of the home at that time. This increases home comfort by gently increasing temperature and giving the furnace a longer run time that allows the heat to travel evenly throughout the entire house. A Two Stage furnace will work best with a two stage thermostat such as the Honeywell Vision Pro 8000. It can function with more basic thermostats, but this limits the operation of the furnace.

Modulating Furnaces:

Modulating Furnaces are able to adjust the heating capacity from 40% to 100% in 1% increments. They also come equipped with a variable speed fan that is adjusted in coordination with the heating capacity. This is like having a sixty stage furnace. With a modulating furnace your home is blanketed in a consistently warm and comfortable environment without hot and cold spots. In fact, the temperature will rarely vary more than one degree! This is the most effective and efficient furnace available.

Variable Speed Blower Motors:

Variable Speed furnaces have a different type of fan blowing the air into the home. It is electronically adjusted to many fan speeds to achieve the best setting to meet the heating needs of the home at that moment in time. This increases comfort and efficiency. The variable fan starts up much slower and runs much quieter, and it can be set on a very low speed when appropriate. At this low setting the house air can be constantly filtered for the same cost as using a 75 watt light bulb.

Electric Furnaces

In homes where natural gas is not available an electric furnace may be the primary heat source. We can replace your aging or failing electric furnace, but you may want to consider adding a heat pump. Adding a heat pump can reduce heating costs by up to 50%, and all heat pumps come standard with air conditioning as an added bonus. Click on the links below to see our featured electric furnaces.
