Gas Furnaces

Gas furnaces are fueled by Natural Gas or Propane. They typically use the forced air style of heating, meaning the air is heated in the heat exchanger of the furnace itself and is then forced through the attached duct-work to the vents that feed the home.

Older types of gas-fired furnaces lose significant amounts of energy in the hot waste gases exhausted up the chimney. More modern high-efficiency furnaces condense the water vapor emitted as one of the products of consumption. This increases the efficiency of the system to over 90%.


Advantages of Upgrading to a Gas Furnace

Cost – Gas furnaces cost less to operate than electric furnaces because natural gas cost less than electricity.

Efficient in Extreme Cold Temperatures – Gas furnaces can warm up your home faster and produce higher temperatures in extreme cold than electric systems.

Compatibility – An air conditioner or heat pump can be added for year-round heating and cooling.

Lifespan – 10 – 20 years. Longer lifespan than a heat pump, but shorter lifespan than an electric furnace.

There are also some disadvantages when considering a gas furnace as well.  Your cost of installation will increase if you don’t currently have a ventilation system, or natural gas lines. Both oil and propane require fuel storage tanks that require installation and maintenance.  Gas furnaces emit a low level of carbon monoxide, so you must have a carbon monoxide detector running in your home and perform regular maintenance to ensure your unit is working properly.

When considering your home heating options, whether to go with an electric or gas furnace, there is also a third option, a heat pump. Electric heat pumps are more energy efficient than gas furnaces and require much less electricity to operate than electric furnaces.

We had a new furnace and Air Exchange installed by E.T. Mechanical last spring. The service and installation was a very positive experience. Just recently Ryan came to do some routine maintenance and he was very prompt, friendly and courteous to deal with. Every time I call their office I receive a very friendly greeting and my concerns are addressed immediately. It's very much appreciated!
