As with condensers there needs to be decisions on furnace effeciencies. An 80% furnace can normally be installed with minimal alterations to the existing configuration. Not so with a 90+% furnace. The condensing furnace now needs condensate plumbing and a completely different venting system. The cost of these ninety percenters is significantly more as well. Return on investment must be considered when choosing! Installation cost increase needs to be justified by energy bill savings so do your homework


Professionals with a gas license is the preffered installation means. It is not rocket science to install a furnace and a homeowner that has a little electrical, plumbing and sheet metal ability can surely do it. Although it is not our intention to hint that it should be attempted. We will answer any questions you may have and even help out if we can. In the name of safety please do not hesitate to email or call us for advice or to finish for you if you are stuck.

Take a close look at your existing furnace. If it does not have an inducer motor (see Pics below) it is no more then 40-50% efficient if your lucky. A new furnace would give 80% effeciency! So with these numbers, you can use half the fuel with a new furnace. With winters being six months of the year, it is easy to estimate that within a few years your $1800.00 new furnace will have paid for itself. Not to mention it would be safer for your home and the environment.
