What Kind of Fuel Does a Furnace Use?

Saturday, January 11th, 2014

Perhaps a better way of phrasing this question is, “What kind of fuel doesn’t a furnace use?” In their long history, dating back centuries, furnaces have used wood, coal, peat, oil, and almost anything combustible. The flexibility of furnaces is one of the reasons they have stayed popular for so long; any home can find one that will work with its available fuel supply.

Today, furnaces typically use one of three types of energy: natural gas, electricity, or propane. Which type will work best for your home depends on a number of factors. We will run down the three major choices in this post to help with your decision. However, you will need the help of home heating experts to make an informed final choice. Call Cowboys Air Conditioning & Heating for all your questions about furnace installation in Boerne, TX.

Natural gas

This is the most common type of furnace in U.S. homes. They run on natural gas piped from a municipal supply. This fuels the burners that create a hot combustion gas that is transferred to the air blown through the ventilation system. Gas furnaces are the most efficient furnace model and cost less to run than other models because gas is a less expensive fuel. They can also reach very high temperatures. But since they require an existing gas line, not every home can install one.


Electrical furnaces are popular alternatives for homes without natural gas. Electrical heating elements inside the cabinet heat up the air for the blower fans to send into the house. Electrical furnaces have lower installation costs than natural gas furnaces and can last longer. They also pose little safety hazard. However, they cost more to run and cannot achieve as effective heating as gas furnaces.


Propane furnaces operate in much the same way as natural gas furnaces, except they use a propane supply kept in a tank. Propane furnaces are less frequent today because propane does not burn as efficiently or cleanly as natural gas, and it comes in a limited supply instead of entering directly into a house. Propane furnaces, however, work very well as back-up units for hybrid heat pumps, and they pose less combustion risk than gas furnaces.

The furnace that will work best for your home is Yet to Be Determined. To find out the furnace that will keep you warm at the right price will require the work of professional installers, who will examine your home and determine its heating needs.

Common Mistakes During Furnace Installation

Friday, December 20th, 2013

Congratulations, you’ve decided to have a furnace installed in your home—either as a replacement for an older system, or as a system for a new home. A furnace should provide you with years of indoor comfort. However, we want to caution you about some of the mistakes that can occur during furnace installation—and the one simple solution that you apply to avoid them.

Call Cowboys Air Conditioning & Heating for more advice about furnace installation in Selma, TX.

Furnace installation mistakes

  • The furnace isn’t sized properly: A furnace cannot be either too large or too small for the space it must heat. An undersized furnace will not provide enough heat and will need to run constantly to strain to reach its target temperature. Too large a furnace and the system will “short-cycle,” turning on and off repeatedly as it reaches the target setting too fast. In both cases, the furnace will rapidly wear down and require premature replacement.
  • The furnace is improperly connected to the ducts: If the furnace you are having installed will hook up to a preexisting set of ducts, careful work must go into securing the new system. Often, some ducts will need to be reconfigured in order to accommodate the new furnace. A sloppy or inexperienced job will result in leaks in the ductwork and a furnace struggling to provide the heat required from it.
  • The ventilation is done poorly: If you have a gas furnace installed, it needs to have proper ventilation to release the combustion exhaust gas after its heat is transferred to the air. If the exhaust flue in the furnace is put in incorrectly with a faulty damper, or if it is the wrong size, it can lead to a dangerous situation where the exhaust flows back into the cabinet or never makes it to the outside at all.

There is a simple way to avoid all these mistakes: hire experienced, licensed professionals to handle your installation, and handle it from the start of choosing and sizing your furnace. If you rely on amateurs, you won’t have any assurance that the work will be done right, and you may even end up with a potentially dangerous furnace in your home! Rely on professionals with a long track history of successful installations.
