testing-furnace-technician-wiringA furnace is a reliable, sturdy appliance. You use it year after year without even thinking much about it—until it doesn’t work. No matter how dependable your furnace has been, you can expect to run into trouble at some point in time. Thankfully, a bit of routine maintenance can help: changing the filter every couple of months and calling a technician at the beginning of the season to do an inspection.

To show you the importance of this, we want to detail a few repairs that could occur in the middle of winter, right when you need your heater most. Some of these are larger issues than others, but all should be repaired ASAP so that the issue does not get any worse. (more…)

The Differences Between Electric and Gas Furnaces

Friday, December 6th, 2013

One of the major advantages of furnaces that keep them competitive in the home heating market is their flexibility. Furnaces come in a huge array of sizes and types, and they can run from a variety of different fuels, so they can fit almost any home. The two most common energy sources for modern heaters are natural gas and electricity, both of which come from a municipal source straight into your home, making them much more convenient than propane or oil.

In this post, we will go over the differences between electric and gas furnaces, which may help you if you are currently considering having installation of one or the other. For more information about how a furnace in Oxford, MI can work for you, contact the experts at Davison Heating & Cooling. Our NATE-certified technicians have many years of experience working with all types of furnaces and other heating systems.

Electric vs. natural: battle of the furnaces

The two furnaces have the same heat delivery method: they distribute heated air using blower fans through ducts and into vents. It’s how they heat the air that makes them different.

  • Gas furnace: When the thermostat sends the signal to the heating system that it requires a higher temperature, a silicon nitride igniter activates gas-powered burners in the furnace. Jets ignite along the burner and creates a high temperature gas, which then enters a series of chambers known as heat exchangers. The metal of the heat exchangers rises because of the combustion gas, and fans then blow air in and over the hot metal, where the heat transfers to the air. The blower fans then take this hot air and send it into the ductwork.
  • Electric furnace: An electric-powered furnace starts up with an electric ignition. Instead of lighting gas-jets, the ignition powers up a series of heating elements, which consist of coils that glow hot as current courses through them. The more heat the thermostat calls for, the more of the heating elements will turn on. The air heated from these elements is then wafted through the vents.

Which is better?

It depends on your home. Obviously, if you don’t have a natural gas line, the electric furnace is the natural option—although you can sometimes have a gas line installed if there is a nearby source. Electric furnaces tend to have lower installation costs and are smaller than their gas-powered cousins. They also pose no risk of toxic gas leaks. On the other hand, natural gas costs less than electricity, so gas-powered furnaces are cheaper to run, and they tend to provide more effective heating.
