How much freon in a 2 ton unit

General Rule of Thumb The general rule amount that can be estimated is in the 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 pounds of refrigerant, to fully recharge from empty.

This includes the lineset, coil and unit. 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. Are you required to have a license or to be certified to handle and purchase RA? If the repair requires adding R22 refrigerant to the system, the only options will be reclaimed and previously-produced R22 refrigerant.

The picture here is the nameplate to a split system air conditioning system. This label states that this 2 Ton outdoor air conditioner requires 3 pounds and 14 ounces of R22 refrigerant. This does not mean that the system only requires 3 pounds and 14 ounces of Freon.

To know which type of refrigerant your air conditioner uses , take a look at the label on the compressor unit outside. It'll clearly tell you which type of refrigerant the unit uses. Up until , air conditioners could still be manufactured to use R refrigerant, and many were.

R32 does not just replace R22 refrigerant. Manufacturers initially replaced R22 with hydrofluorocarbon Rc because it had similar operating characteristics. In the market moved to RA refrigerant as it offered better efficiency. These refrigerants also contained greenhouse gases. As the cost of R22 increases exponentially, the cost of RA has been dropping.

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. There are no different coil sizes to deal with and the lines connecting everything are self-contained in the same box.

Fortunately, most Charlotte AC Contractors are honest and treat customers fairly. If you think you may have been taken advantage of during a recent home ac recharge, make sure you ask them about it and give them a fair chance to explain their pricing and reasons for using the amount of refrigerant they did.

Our coil and ac are approx. The coil was bad, so we had to have it done. In reality, your three ton coil may work for a short period of time, but its not large enough to adequately dissipate the cold temps of the refrigerant and will turn into a block of ice. In addition, if your indoor furnace or air handler only pushes cfm of airflow, even if you put a 4-ton coil onto the unit, you may have problems with icing up.

You may need a higher capacity blower in the furnace as well. Just had a new 2 ton put in, the line just a foot away from the unit leak out the refrigerant. We solved my air conditioning problem from above. My unit kept freezing up. I was told my outside unit leaked and needed replaced. I replaced the 3 ton unit with a 4 ton unit.

It still froze up. I was then told I need new coils and a new blower to handle the air flow of the 4 ton unit. I found that my son in law had a friend that was an air conditioning man. Now that 4 ton will freeze you out of the house. By the way I live in a 75 foot trailer house. Since most of the homeowners are not very knowledgeable about this matter, we have some pieces of information to guide you in getting the answer to your concern.

However, this general rule of thumb may depend on different variables. The size of your air conditioning unit significantly affects the amount of refrigerant needed to produce cool air. Of course, the bigger unit needs a larger liquid line on the line set, thus requires greater capacity. Length and Size of Copper Line Set. The greater the distance between the evaporator and condenser coils, the more refrigerant is needed.

Air conditioning units come from the factory with the right amount of refrigerant which complies with the distance between these two crucial parts. Size of Evaporator Coil. Many homeowners would prefer larger evaporator coils for greater cooling power and efficiency. This however also means, your unit needs a greater amount of refrigerant inside. Type of System.
