Which refrigerants are HFCS?

HFC Refrigerant: HFC refers to the chemical composition of the refrigerant. Hydrofluorocarbon indicates that the refrigerant is comprised of Hydrogen, Fluorine, and Carbon. Common HFC refrigerants are R-32, R- 125, R134a, R-143a, and R-152a.

Is R22 a HFC refrigerant?

R-22 is an HCFC refrigerant that is often used in air-conditioning equipment. To protect the Earth’s protective ozone layer, the United States is phasing out R-22, along with other chemicals.

Is R410A a HFC refrigerant?

R410A is a HFC blend, used mainly in air conditioning systems; it may also be used as an alternative to R13B1 in low temperature refrigeration.

What refrigerant will replace R410A?


What is HFC R410A?

HFC-410A, or better known as R-410A, is a refrigerant blend of R-32 and R-125. Both R-32 and R-125 are hydrofluorocarbons (HFCs). HFCs are void of chlorine, thus have a zero ozone depletion potential (ODP). HFCs do have a global warming potential (GWP).

Is AZ-20 The same as 410A?

Genetron® AZ-20® (an azeotropic mixture of HFC-32/HFC-125, assigned R-410A by ASHRAE), has been developed by Honeywell to serve as a long-term, non-ozone-depleting replace- ment for HCFC-22 in a variety of new-equipment applications. Because it behaves like an azeotrope, Genetron AZ-20 is easy to service in the field.

Why is R410A being phased out?

All new home AC units in North America uses R410a, also known as Puron. But this refrigerant will consequently be phased out. This is due to a continued focus on reducing compounds known to have an effect on the environment. But it’s not so much the air conditioning system itself, or even its cooling performance.

How cold is 410A refrigerant?

A normally operating R-410A system with the same condensing temperature of 120 degrees and a 45 degree evaporator saturation temperature will have a high side pressure of 418 psig and a low side pressure of 130 psig.

What is suction and discharge pressure of R410A?

Recently a new refrigerant, R-410A, has been formu- lated and currently is being used in the HVAC/R industry. With R-410A, the same unit will operate under the same conditions with a suction pressure of 118 psi and a discharge pressure of 400 psi, as shown in Figure 1 on the next page.

How do I know if my 410A is overcharged?

In summary, there are seven symptoms or telltale signs of a system that has too much refrigerant.

  1. High discharge temp.
  2. High subcooling in the condenser.
  3. High pressures in the condenser.
  4. Higher condenser splits.
  5. Normal-to-high evaporator pressures.
  6. Normal superheats.
  7. High compression ratio.

Can I replace r22 with R410A?

R-22 refrigerant is skyrocketing in price due to government mandated reductions in production, and it is never going to get cheaper. To retrofit an R-22 system with R-410A system your line set must not be more than 25-50 feet in total distance.

What’s the best replacement for R22?


How much does it cost to convert R22 to R410A?

The cost to convert a central air conditioner from R-22 to R-410A can range anywhere from $2,000 to over $4,500 in the New Jersey area. The bottom line? If your AC unit is 8+ years old, it’s usually not worth the cost to convert and you should just replace the entire R-22 unit with an R-410A unit.

Can you write off a new HVAC system on your taxes?

There is a new tax law that allows business owners to immediately expense their air conditioning, heating, and ventilation system. Under this new tax law, you can offset the cost of a whole new HVAC system for up to $5,000 or more. Now you can quite literally write off each and every component of your new HVAC system.
