Furnaces

Some are, some aren't, like most mechanical devices.

SIMPLE ANSWER IN NORTHERN STATES IS ABOVE FREEZING. FLOORING AND FURNITURE FACTORS AFFECT THE ANSWER FROM A HUMIDITY STANDPOINT IN THAT IT WILL AFFECT THEM ADVERSELY AND ALLOW FORMATION OF MOLD, ETC. IF NOT CONTROLLED IN HIGHER HUMIDITY AREAS. LC

It means the Phase anlge is not matching with control board phase angle or more capacitor connected in the furnace line. we have to Remove some tank capacitor.

Remove the top panel and look up inside. There will be two filters in a V pattern.....unless you bought a forclosed house, then there might not be any filters. In that case, look for channels in the middle--one angled to the left on the left side and one angled to the right on the right side. The top of the filters will just lay over and touch the sides of the furnace.

Yes there are a few difference's. Manufactured homes ( by code) require a furnace designed for manufactured homes. There are a couple of regular furnaces that are rated for "manufactured home use". This all has to do with combustion air taken from home. This answer is a little generic but I hope it helps.

There are a couple common reasons for a pilot light going out. 1. The thermocouple is weak. This is the gold rod that must see the flame in order to keep the gas valve open. it is a safety device that will not let the gas vavle open if there is no pilot. 2. The pilot is dirty and has a yellow flame. If this is the case, it will have to be cleaned. There are books on he market such as forced hot air furnace - troubleshooting and repair that show you how to repair your furnace. You can buy this at amazon.com

An up-flow furnace is a heating device that draws in air from near floor level in a building, heats it and then discharges the warmed air through a vent or plenum at the top of the machine. The warmed air is then fed into ductwork that distributes it throughout the building. This type of furnace is useful for installation below the area to be heated.

My "furnace" is a boiler with one zone circulating the entire house.

I have a wood burning fire place on the main floor. The thermostat is also on the main floor.

When I burn the fire place, the main floor heats up and the lower floor gets colder than crap.

I want to install a second thermostat on the lower floor to keep the boiler @ 70 degrees....to keep that lower floor at 70 degrees....inspite the fact that the upper floor, with the fireplace burning, raises the temp on the main floor up to as much as 80 degrees!

Yeah, yeah, why burn the fire place and the boiler at the same time. Answer, to keep the lower floor warm!

Can't run duct work from the main floor fire place to the lower floor in a finished house!

Inventor Granville Woods received his first patent on January 3, 1884 for a steam boiler furnace.

The thermocouple is two dissimilar pieces of metal inside a tiny metal bulb. When heated they then generate a tiny electrical charge that gives a signal to the gas regulator to keep the pilot on.

Average is around 15 years although some may last as much as 20 years. Of course some last as little as 10 years. Usually the first things to fail are the parts associated with the blower. Anything that can wear out the motor quicker will shorten the life of the furnace such as: high humidity, vibration, inconsistent power, power surges, water leakage, very gritty air.

The cost to replace a boiler depends on your existing setup, whether you need permits for the replacement, or if additional service is required. Sometime it is necessary to line the chimney or remove an older fuel tank. The total cost should come in around $3500-$7500 based on the above information.

To light the gas burner on your furnace, first ensure the thermostat is set to a temperature that calls for heating. Locate the gas valve and turn it to the "On" position. If there is an ignition button or pilot light, follow the manufacturer's instructions to ignite it; this usually involves pressing the button while holding a flame near the pilot light opening. If the burner doesn’t ignite after following these steps, consider checking for gas supply issues or contacting a professional for assistance.

If you put a 85 amp breaker in there it will overheat from the starting and stopping of the motor. The extra size of the breaker insures that the furnace will run without interruption and without overheating the breaker. And electric motor can draw three times the amperage rated on start up momentarily. This is why there is need of extra amperage ratings.

This is how a furnace heats your home. When the thermostat calls for heat, a signal is sent to the gas valve. If you have an older unit, the gas valve checks to see that the thermocouple sees the pilot and if it does, the gas valve opens to send gas to the burners. If you have a newer furnace, the thermostat sends a signal to start the pilit ignition sequence (either spark or hot plate) and then the flame rod sees the pilot (of the hot plate is up to temp.) the gas valve opens to send gas to the burner. The fan control will then send a signal to the blower to start up. As the temp rises in the room, the thermostat sends a signal back to the gas valve to close as it reaches the set point on the thermostat and the blower continues to run until the set point on the fan control is reached and it shuts off ending the cycle.

Generally, the thermocoupling is screwed on to the end of the line. It is usually bullet shaped and about 1 to 1-1/2 inches long. Just unscrew it to remove.

they are furnaces which means texture when you try to clear.there are 1000 difernt ones lioke blue green brown and orange the most popular is green.

If you live in a colder climate where there is snow, you should check your outside air intake pipe to make sure it is not covered in snow. The pipe needs to be clear in order for it to be able to draw air into the house. This simple tip may save you big $ on a service call.

A gas furnace works by heating up the element inside the furnace. The gas comes into the furnace and is lit by a spark that comes from the pilot light. The fire heats up the element and air from the fan pushes the heat into the house.
