How many pounds of refrigerant per ton

However, most home air conditioning units are between one ton and five tons. Anything over five tons is considered a commercial grade unit. A two-ton system would need eight pounds of refrigerant to completely refill your unit two tons x four pounds. That is a big price difference! A company will need to mark that charge up in order to stay in business, but it pays to know exactly what the current cost is to determine if you are getting a fair deal.

Another important note: You should never have to continuously add refrigerant to a system. If that is the case, you probably have a leak which could result in a much larger repair, for example, replacing the coil. If your system is old and out of warranty, this can be a pricey repair and perhaps time to consider upgrading your system. Check out these great tips for air conditioning troubleshooting. Now that you know exactly why air conditioner refrigerant costs vary so much, you can better judge what you should be paying.

And keep your eye on the market prices, as after , they will most likely double again. Remember Me. Learn more. You'll need 2- 4 pounds per ton of AC cooling. Beside above, is 2 pounds of Freon a lot? The tonnage of an AC unit determines its size and the amount of space it can cool, with larger tonnage units providing greater cooling abilities.

For example, a 4 - ton AC with a very bad refrigerant leak that's been ignored for months may need a complete fill-up, which requires approximately 16 pounds of R General Rule of Thumb The general rule amount that can be estimated is in the 2- 4 pounds per ton of cooling for your system.

For example: 3-ton AC or Heat Pump with a 35 foot lineset will need a total of approximately 6- 12 pounds of refrigerant, to fully recharge from empty. This includes the lineset, coil and unit. The rule of thumb is two to four pounds of refrigerant per one ton of your unit. You should always check the specifications of your unit.

Most systems move the heat from the inside of your home to the outside. Ice buildup on the outside unit. Hissing noise is noticeable. Visual detection. The best replacement for R Freon is usually Rc. If a system has R22 in it already you cannot use a replacement refrigerant to simply add to the R A 3-ton air conditioning unit can hold 6 to 12 pounds of Freon, depending on the unit.

The exact amount of Freon needed is determined by a variety of factors, such as the type of unit and where it is installed. Actually, Freon lasts forever. The only reason you would need more of it is because of a possible leak. Since the said refrigerant is circulated through copper refrigerated lines to keep your humble abode cool and keep the heat away, it stays inside the air conditioning unit, forever.

R22 is being replaced by RA, a safer material which is the current, compliant standard refrigerant in air conditioning equipment. Your existing condensing unit and cooling coil are not suited to the new higher pressure refrigerant.

It is possible to reuse the copper tubing lineset between the two, but we will discuss that later. Simple: supply and demand dictate market prices. With less Freon available on the market, the cost has to rise to compensate and temper the demand for the substance.

As a result, the high cost will in turn cause demand to drop as people start looking for viable alternatives that are cheaper. Most systems move the heat from the inside of your home to the outside. Ice buildup on the outside unit. Hissing noise is noticeable. Visual detection.

Perform a soap test. Use an electronic detector. How many pounds of r22 are in a 2 ton unit? Category: home and garden indoor environmental quality. Most manufacturers put enough Freon into the outdoor unit to compensate for up to 15 feet of line set.
