Whats the difference between an electric and gas furnace? as far as cost and upkeep go?
May 19, 1575 by BS and thats no BS
I'm looking at Condos right now one has a gas furnace and water tank, while the other 2 have an electric(forced air) furnace and an electric water heater.
Which is more expensive to run in terms of energy bills? Do Electric Furnaces last longer then gas? Are they cheaper to replace? Does an electric furnace use a heating element or what?(vs a gas using a flame)
The one I'm looking at still has an electric furnace from the mid 70's. Should i be worried?
Electric is MUCH more expensive to operate. It uses something called "heat strips" to provide heat. Have you ever seen a fake fireplace that provides heat by blowing air over a coil that heats up? It provides heat but is very expensive to run because it has to keep the coil red hot to provide heat. Well that's the same way an electric furnace is going to heat your condo, except it has strips that it heats up and blows air over.
I would definitely go with the one with gas heat. By the way, a forced hot air furnace can still be gas. That's what we had in New Jersey and my bills were not out of line.
A gas furnace costs more to replace, but a lot less to operate. Same with a gas dryer. It's more to purchase, but less to operate.
An electric furnace from the 70's is probably not a very energy efficient model so I would definitely think twice.
Good luck with finding your new condo and happy moving!!
Why is my natural gas furnace making buzzing sounds?
Nov 30, 2007 by Glenn
I have a natural gas furnace and noticed that on an intermittent basis it makes a buzzing sound. At first the buzzing sound didn't happen that often, but now it is happening more frequently.
The furnace will buzz for several seconds and then stop. Then at some random point it will buzz again for another few seconds. This only happens with the furnace is actually running.
The furnace is still producing heat. In fact, apart from the buzzing sound, it is working normally.
Well you got all the smart answers, now I'll try to actually held you.
Your gas furnace has a blower motor. There usually is a metal access panel over the internal parts of the furnace. Next time you hear the buzz, go to the furnace and put your hand on the panel, I'll bet it is vibrating when the blower motor is working. If it is not that panel, try a different panel.
When you find the buzz panel, you'll have to secure it so it doesn't vibrate. If this doesn't fix your buzz noise, you may be forced to call a repair man to do more investigating, but it's usually some that gets lose when it gets warm. I would be surprised if it were not just a lose panel cover.
