Getting right to it, the fundamental difference between the two is in the direction of air flow in and out of the furnace. A Upflow furnace takes in existing air from the bottom of the furnace and blows out filtered warm/cool air through the top. A downflow furnace works in the opposite way.

How do you know what kind of furnace you have?

Take a quick look at your furnace unit. Check for either gas pipes or electrical wiring, which should give you an indication of which kind of furnace unit you have.

What is the difference between updraft and downdraft furnace?

The primary difference between an updraft and downdraft unit is where you can install them. The updraft unit is common and works best if you can place the system in your garage or basement. … A downdraft unit is used when there is no basement space, but the house has enough attic space to accommodate the system.

Where would an upflow furnace usually be found?

It’s typically used in basement, closet and attic installations. Upflow, or vertically configured furnace installations are among the most common in North American homes, which is why Lennox carries some of the shortest gas furnaces available.

What is an upflow horizontal furnace?

An upflow furnace takes in air from the bottom of the unit, warms it in the heat exchanger, and then blows it upward into the ductwork of your home. Upflow furnaces need to be placed in a basement or crawlspace to be energy efficient, as they work on the principle that warm air rises.

Is my furnace under the house?

Typically, your furnace is centrally located in the home. You can usually find it in an area such as a utility closet (by a cold air return), a garage, an attic, basement, or crawlspace.

How can I tell if my furnace is gas or electric?

If you see a blue flame, it’s a gas heat exchanger. Other units will have a small metal panel that’s easy to remove. You can check behind there to see if you see that blue flame. Electric systems don’t have that access window or panel and make very little noise.

Which way is the airflow on my furnace?

If you are looking at a furnace filter, find the arrow that indicates the proper air flow direction. That arrow must always face toward the furnace and away from the return duct that carries the air in need of heating or cooling.

What is an upflow?

Upflow furnaces blow heated or cooled air upward and are installed in the lowest level of your home. An upflow furnace is the best choice in cold climates where it is used for heating more than for air conditioning.

What is a downdraft furnace?

A downdraft furnace pulls in air from above, heats it, and sends it out to ductwork that rests below the unit. These types of furnaces are commonly mounted in the living area of a home, either in a closet or an access room. The ductwork is mounted below the floor to distribute the heated air evenly to the living space.

Application : Vertical Type : Cased A. Find A Contractor. chevron_leftchevron_right.

Can a universal furnace be used as a downflow furnace?

An upflow / horizontal furnace can be configured as either an upflow furnace, or a horizontal (left or right) furnace. It cannot be installed as a downflow furnace.

Can any furnace be installed horizontally?

Up-flow/horizontal and down-flow/horizontal furnaces can be installed horizontally, but the airflow direction in them can’t be changed. … These furnaces and air handlers can be installed either horizontally or vertically, and the air flow can be changed to fit the home’s needs.

Does Goodman make a downflow furnace?

× Modulating/Staging Stages are unique speeds or levels that equipment can operate at. More stages allow for better fine-tuned control of output, which improves comfort and efficiency. Modulating equipment can operate across a range of levels, giving the highest level of fine-tuned control.

Where is my furnace pilot light?

Near the bottom of your furnace is a switch that normally says “Pilot,” “On” and “Off.” Find this switch and turn it to the “Off” position. Wait at least five minutes. This is important because it gives the gas time to dissipate, which is necessary to avoid possibly starting a fire.

Why does my furnace not turn on?

The Pilot Light (Faulty Ignition Sensor) The pilot light or ignition sensor is usually the most common issue when your furnace will not ignite. This is typically the problem if you can hear your furnace click on but it does not fire up. … Turn up the temperature on your thermostat to see if your furnace will now fire up.

Do gas furnaces use electricity?

A gas furnace uses the burning of natural gas to create the heat that then goes through the ventilation system. … It’s like an old-fashioned stove this way: no need for electric power, just plain old heat from consuming another power source.

Does central air use gas or electric?

There are many different brands, models, and types of central air conditioning systems. Each model has unique features and energy efficiency ratings. However, all central ACs have one thing in common: They all use electricity, not gas.

What is upflow installation?

UPFLOW INSTALLATION Drill screws are used to engage the furnace top flanges. The standoff is inserted into the cabinet alignment hole. The drill screws are inserted through the standoffs then screwed into the furnace flange. The coil is always placed downstream of the furnace air- flow.

Where does the coil go on a downflow furnace?

In a downflow furnace application, the air conditioner evaporator coil will sit below the furnace. In most applications, the furnace air filter will reside above the furnace, and the evaporator coil will sit near the ground or floor.

What is a downflow kit?

DOWNFLOW KIT. Page 1. DESCRIPTION. The DFK Downflow Kit is applied to the bottom of the drain pan to prevent possible condensation from forming on the drain pan in the downflow application.

Can a furnace be outside?

Placing a gas furnace outdoors is an option for homeowners with limited space or the need for a large furnace that would be difficult to install inside. Outdoor gas furnaces burn natural gas and can keep an entire home warm throughout the winter months for a minimal cost.

What is home furnace?

Furnaces. … A furnace works by blowing heated air through ducts that deliver the warm air to rooms throughout the house via air registers or grills. This type of heating system is called a ducted warm-air or forced warm-air distribution system. It can be powered by electricity, natural gas, or fuel oil.

Can a furnace be in a closet?

The heat can safely escape if there is space around the furnace. Do not install your furnace in a storage closet. Any type of flammable material, including insulation, needs to be removed before installing the furnace.

Why was my furnace installed upside down?

A: Short answer: New models of furnaces allow this upside-down installation. Why is that? … Conversely, if the return side is physically at the bottom of the furnace, the cold air enters from below, the furnace heats it, and the hot air is propelled into the supply side above the furnace.

In which type of furnace does the return air enter through the bottom?

Upflow furnaces receive air intake at the bottom, heating cool return air and pushing the newly heated air up to your living space through supply ducts and registers. Upflow furnaces are installed in homes that have basements and are generally preferred over downflow furnaces for overall comfort and efficiency.

What is a downflow unit?

A downflow furnace takes in cold air at the top of the unit and expels air at the bottom. By doing this, the downflow furnace directs heat downwards towards the area that requires it. This makes downflow furnaces naturally suited to being installed in attics.

Which way does the arrow go on a furnace filter?

The arrow points in the direction of the airflow. The point should go toward the inside of the furnace compartment. If the filter goes inside the ductwork, it should point toward the air handler or the furnace.

Does the arrow point up or down on an air filter?

For any air filter, whether it be for an air conditioner or a furnace, the ARROWS ALWAYS POINT IN THE DIRECTION OF AIR FLOW. When you install a new air filter into the AC return duct, the arrows face inward to specify which way the air is flowing.

What is a downflow air handler?

Also known as “downdraft” or “counterflow” furnaces, downflow furnaces are designed to bring in cool air through the top of the air handler and release heated air from the bottom. These models are usually installed in the attic or, less often, in a closest on the home’s main floor or in the garage.

How much should it cost to replace evaporator coil?

Residential AC Evaporator Coil Replacement Cost Replacing a home air conditioner’s evaporator coil costs $1,000 on average with a typical range of $600 to $2,000. About 40% of the bill comes from labor, or $400 to $1,000.
