It’s entirely possible to install a furnace without ductwork in a basement or shop if you’re not too concerned about the distribution of the air. I have to assume a couple of things here. My first assumption is that this would be an unfinished basement, and you want the most cost-effective way to heat it….
A gas furnace sequence of operation begins with a signal from the thermostat to start the furnace. Next comes a call for the inducer motor to prove that venting will occur. Most thermostats these days are digital and will display “heat on” somewhere on the screen depending on your type of thermostat. With the thermostat…

Here’s why: Breakers are an important safety feature of air handlers or furnaces. Circuit breakers are not just a switch to turn a furnace on and off. They protect the wire that…
If your gas furnace is leaking water in the winter, it’s likely a high-efficiency (90%+) model. These furnaces create condensation as a byproduct of pulling more heat from the exhaust gases. If the drainage system is clogged, damaged, or poorly installed, that water can leak out and rust the cabinet or floor below. Not all…
