Where is the air handler on furnace?

The air handler is the large metal box containing the fan and fan motor. Typically, the unit would be found in a basement, an attic, or sometimes in the back of a closet. Once it is located, look for a slot where an air filter should fit.

All air handlers must contain a heat pump/AC coil. They use the coil to distribute heat gathered outside. … If the system does not include central air conditioning, there is no need for a coil. If AC is part of the system, the furnace will contain a coil.

A good sign something is wrong with your air handler is when the condensate pan is leaking. During the hot summers, hard-working AC units will create a lot of condensation that accumulates in the pan below the air handler. If algae or mold builds up in the lines, it can clog the drains.

Yet as recently as 1993, only 68 percent of houses in the United States had some cooling equipment, either window air conditioners or central AC systems. Now, more than 87 percent of houses are so equipped.

The air handler is responsible for regulating and circulating hair. It contains the system’s blower, evaporator coil, sound dampers, filter racks and other parts of the ventilation system. An air handler houses all the components necessary to circulate air throughout the building.

The air handler is the indoor part of your AC system—and a vital part, at that! … The indoor air handler unit comprises an air filter, coil, and blower. The handler pulls air in, passes it over the coils (to cool or heat), and then blows it back out into the home through the duct system.

Whether a home has a furnace or an air handler depends on the kind of heating system it has. If you heat your home with gas, liquid propane or heating oil, you probably have a furnace. If you have an electric heat pump, you probably have only an air handler.

An air handler costs $500 to $3,500, with most homeowners paying $700 to $1,500. This does not include installation, which averages $1,500 and ranges $200 to $2,100. Air handlers connect to an air conditioner or heat pump to provide cooled or heated air for an indoor space.

Does air conditioning use gas or electricity? 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.

1. Shut it Off. First, turn off your AC before resetting the thermostat. …
2. Get to the Circuit Breaker. So far, so good. …
3. Wait 30 Seconds. After turning off the circuit breaker linked to the AC unit, wait for a full minute. …
4. Turn it Back On.

Air conditioning unit life expectancy Air conditioning units generally last around 15 years or so. If you want your air conditioning unit to live as long as possible, you want to get it maintained twice a year. Your AC, like your furnace, should be sized correctly for your home.

Simply put, an air handler “handles air” around the house via ductwork. An air handler is installed inside and works with an outdoor air conditioning and/or heat pump condenser unit to make the air hot or cold. A blower fan that moves the conditioned air throughout the home via ductwork. …

Rule of thumb #1: One air handler per room Like we mentioned earlier, you’ll need a separate air handler for every room you need cooled. Note: A separate ductless air handler is not needed for small, half bathrooms or hallways. Usually, those rooms will get plenty of cool airflow via larger, nearby rooms.

Replacing just the air handler might appear cheaper right now, but over time, it will cost more in repairs, time, and high utility bills because it is inefficient.

Size your air handler. Size your air handler unit based on the size of your air condenser unit. If your air condenser unit needs to be four tons so must your air handler. You can put a larger air handler by one ton more, but for optimal performance they should match.

Just like a furnace, air handlers contain a blower (fan), controls, and an evaporator coil that conditions and recirculates the air in your home. The air handler works with the outdoor unit (a condenser or heat pump) in a typical split-system by using refrigerant lines that connect the two systems.

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.

AC not turning on could be the result of a blown fuse located at something called a safety shut-off box. This should be found close to your AC unit. Check to see if you have a blown fuse, and be sure to replace it if that’s the case. Even if the fuse doesn’t appear to be damaged, go ahead and replace it anyway.

An AC’s reset button is typically red and visible, so it should be easy to spot. If you don’t see a reset button on the outside, it could be located inside the unit behind the service panel. Before poking around inside the machinery, be sure to cut power to the system by flipping off your circuit breaker.

1. Step 1: Turn off the power to the furnace. …
2. Step 2: Remove the blower compartment cover. …
3. Step 3: Make sure the blower is completely cooled off. …
4. Step 4: Locate the reset button. …
5. Step 5: Press the button in (assuming that this is your issue and that the button has popped).

In most cases, a blower motor resistor fails due to corrosion or overheating. Sometimes, the mechanical resistance to the motor rotation causes an excessive electric current that can overheat and prematurely damage the blower motor resistor.

In general, most HVAC systems will last from 15 to 25 years, but depending on the type of system and other contributing factors, that estimate can be highly variable.

If it is a straightforward AC replacement with no issues, expect the job to be done within 2-6 hours, depending on the size of your home. However, if it is a first-time installation, it will always take longer.
