How do you change an air conditioner pipe?





Quote from the video:
Quote from Youtube video: But you'll need to measure your outside diameter of your pipe. And find out which works best for you. So this is a very thick insulation here it's a like a micro cell kind of a foam.

How do you remove refrigerant from AC lines?

There are two methods of removing refrigerant from a system. The first is to pump all available liquid into an approved refrigerant cylinder using the refrigeration system containing the refrigerant. The second is to use refrigerant recovery equipment commercially manufactured for refrigerant recovery.

What are the two pipes from my AC unit?

Those are the refrigerant lines (what I would call Freon lines) that feed the condenser (the thing outside; half of a split system. The other half is the coil inside your furnace’s plenum chamber). The big one (cold) is the suction line. The small one is the liquid line (hot; no need for insulation).

What are the two copper line on an air conditioner?

Refrigerant lines are two copper lines that connect the outdoor air conditioner or heat pump to the indoor evaporator coil. The larger line typically carries a cool gas and is insulated. This is commonly referred to as the suction line, but it is also called the return line or vapor line.

How much does it cost to disconnect an air conditioner?





AC disconnect units range from $20 to $75 for residential homes, with the average being $35. Your electrician should inspect your air conditioner to determine the type of disconnect you need.

Should AC pipe be insulated?

A typical residential AC unit has two copper lines that both exit the building exterior and run to the outside condenser unit. Only one of these copper pipes, the cold line, should be insulated. This is called the “suction” pipe and is typically the larger of the two pipes.

What type of insulation is used for AC pipes?

There are several available options for insulation material: fiberglass, foam rubber, and polyethylene foam. The best of these is polyethylene foam. Installation is easy, as the foam is split down the length of the insulation and the edges are covered in a sticky adhesive.

Do AC lines need to be insulated?

Most air conditioning systems have a low-pressure and a high-pressure refrigerant line. Of these two lines, you typically only need to insulate the former. Insulating the high-pressure refrigerant will protect against condensation.

What is the big pipe leaving the air conditioner?



COPPER PIPES



The larger line typically carries a cool gas and is insulated. This is commonly referred to as the suction line, but it is also called the return line or vapor line. The smaller uninsulated line typically carries a warm liquid. It is most often called the liquid line.

Does AC drain line need AP Trap?

A P-Trap serves a very important purpose on an A/C unit. When moist air hits something cold, the water condenses out of the air and collects on the cold surface. Air Conditioning units pull A LOT of water out of the air.

Should the AC drain line be capped?

If the coil is on the negative side it will need a trap and needs to be capped. If you don’t cap the trap on the coil side. The primary line on the pan will suck air not allowing the water to drain while the system is running.

Is it safe to pour bleach down AC drain?



It’s going to corrode! Using bleach or vinegar can be especially risky if you think your AC drain line is clogged. If the drain line is clogged, the corrosive mixture will simply back up in your drain line and flow into your drain pan, which in turn can damage your evaporator coil.

Where does condensate line drain?

In newer homes, HVAC condensate drains are tied most often to bathroom drains. Common drain lines inside your home include in your bathrooms (sinks, shower or tub, toilet), kitchen (sink, water line to your freezer), laundry room, and water heater.

How far should AC drain line be from house?

The condensate drain line is a white circular drain pipe not less than 3/4 of an inch in diameter. The problem that I see often as a Licensed Home Inspector is that most a/c condensate drain lines are routed outside, which is ideal, but stop or terminate 2 to 3 inches from the homes foundation.

Can AC condensate drain into sewer?

Most condensate drains tie into the home’s sewer line and are equipped with a U-shaped trap to keep sewer gas odors from entering the HVAC system. If you notice a noxious odor coming from the supply vents when the blower is running, a dry drain trap may be the culprit.

Can the furnace drain and the air conditioning drain be run with a common drain?



In general, you should not run the air conditioning condensate drain and the furnace condensate drain into a common line. The positive pressure from the coil can travel through the drain to the furnace drain and cause the vent safety switch to trip.

What is a condensate drain?

This is what is known as your condensate drain. When you run your air conditioner, water collected from the air will drip out. That water will need somewhere to go, and that is where this drain pan comes in. The condensate drain allows the water to go into the drain pan and out into the drain line.

Should my exterior AC drain pipe be dripping water?

The condensate line should drain to the outdoors and during humid weather you should see plenty of water dripping from it. If it’s not dripping, it’s not draining! If there is standing water in the drain pan, your condensate drain is clogged!

What is AC condensate?

Condensate is the water that comes from your A/C evaporator coils when the system is running. It is normal to have condensate. This condensate water generally goes into a pan that is under the system or is built into the unit.
