how to charge home ac unit with r22

R22 is an old-style refrigerant gas previously used in air conditioning systems and other cooling equipment. To combat the problem of the ever-increasing hole in the ozone layer, it was agreed under the terms of the Montreal Protocol that ozone-depleting substances, including CFCs and HCFCs, would be phased out globally to help stem the problem. It is now illegal to sell equipment containing R22 gas and many manufacturers are unable to provide even spare parts for these older systems. You are also unable to buy R22 gas in its original, untainted form although some alternatives are available; again, these alternatives are also being phased out. As a result of these changes, if you have an R22 system and it suffers a gas leak, it may not be possible to repair or refill your system. If your unit is your sole source of heating or cooling and you have a failure, you may well be without heating or cooling for a considerable period of time. This could be potentially catastrophic if, for example, your system is being used to cool a server room.
In the case of a major failure such as a blown compressor then, in all likelihood, it would not even be possible to reuse the existing pipework because of contamination within the system, further delaying any repairs or replacement while increasing the costs of such a replacement. R22 replacement is a cheaper alternative to replacing the entire system as we need to replace the outside unit (condenser). In some cases, depending on the manufacturer and type of unit, you may need to replace the indoor units but not the interconnecting pipework. This upgraded system will then run on the newer, more environmentally friendly gases. If your R22 system has been maintained and is still working correctly you can certainly benefit by pre-emptively changing to a compliant and newer R22-replacement system. Not only will this changeover be at a lower cost than a total system replacement, but you will also benefit from lower running costs and the inevitable total replacement costs that you will incur at some point in the not too distant future.
Another advantage is you can do this changeover at a time that suits you so you can plan your business activities or home life around it. From the point of view of longevity, cost, forward-planning and long-term efficiencies, R22 replacement is the sensible choice. For Pricing and Expert Advice Call Our Maintenance Team on: 020 3740 2122 We will provide a full survey by our Air Conditioning Specialists to confirm if R22 replacement is the best option for your system. We look at the existing units to check that they are capable of handling the newer gases. Other factors that we take into account would be, for example, whether pipework was installed at the same time as the building was constructed; very often the pipework is buried in concrete or behind walls. As such, it may be easier to use the use the existing pipework. However, if your existing system is eight, ten or 15 years old, then so is the pipework! As newer systems run at much higher pressures than older R22 systems, the sensible option may still be to replace the pipework at the same time.

As for the bad reviews on here, they are either lemons, or much more common it isPayne is a Carrier brand, but unlike Carrier, Payne is sold to anyone with HVAC certification. installers are less experienced, leading to errors that shorten the life span or cause the system to prematurely fail. Find someone reputable toDon't rely on home warranty technicians, have someone follow up and inspect the work. Do your homework on the technician, it makes a big difference. A common issue that I have heard of with these units are when R22 is used. I have read a large number of those using R22 suffer compressor blowouts. There are laws since 2010 against using R22, so be careful of any installer who wants to use a dry charge system and use R22 instead of 410A. I highly recommend use of 410A even if the cost the replace the lines is very expensive. I'd say on average expect about 10 years of life with this unit. Purchased brand new and installed unit in September 2015.
the following Spring, May 2016. The guy who installed it came back and told me valve was defective, and Freon had leaked out. All I can says is Payne has the worst, cheapest units. I bought this unit back in 2010. I had problem with my Payne unit the first month after the technician installed it. I had nothing but problem after problem. Every time the season changes the unit fails to work. The technician has come to fix the unit more than 20 times. Every time I call and email the company about my unit they always give me the runaround. No one ever returned my calls. I waited 6 months, and they finally replied to my email and said we cannot help you, call your technician. This is very very bad customer service. They don't care about their customers at all, all they do is get your money and ignore everything else. I'll do more research before purchasing a different brand of unit. I'll throw this Payne in the trash.Only unit available on Labor Day weekend in our vacation home.
Due to humidity control we leave it on when we are not there. Every fall when heat is needed, the unit won't work, including 2 months after install. covered initial parts but we had to pay service calls. expired we paid another appliance company to replace the motor ($700). 2015, the unit would not work again, it needs module in motor & relay. a Florida homeowner with central heat & air for 45 years & have never had a unit that fails every year! Will never purchase a Payne again as it has truly been a royal pain. "Great air conditioner, a little loud" I have owned my Payne central air conditioning unit for as long as I have owned my house, which is 6 years. I have been very happy with the unit's performance, it cools the house very well and has been incredibly reliable over those 6 years with no need for major service. The cost to use it is reasonable and it does not run for excessively long periods, even in the heat. I will say that I dislike the noise, the unit tends to be a bit louder than my previous unit (rental, do not recall the brand).
This can be distracting at times and I do wish I had a quieter unit. I think if I would go back and buy another unit I would likely stick with Payne as a brand because I am very impressed with their reliability, but I would likely look at other options for models with more of an emphasis on noise and sound. I would definitely recommend the brand to a friend and if they are okay with noise I would recommend this model. I recently purchased a shopping center and had to replace four AC units. The company I used and trusted recommended Payne for all four units. fan motors have already quit in two of them after only 16 months, costing over $500 a piece ( the only thing covered longer than a year is the compressor ) and the technicians said it is a known problem and the other two units would surely fail as well. They did not even replace with the original Payne part because they said it still has the sameI no longer use my trusted HVAC company and will certainly
never buy Payne again. Don't make the same mistake. Tried to call Payne for a service manual and they basically refused toThey told me that they wouldn't even tell me where the furnace filter was so that I could replace it. What a load of cow manure! would never deal with them again.. First experience with a company being Payne a/c unit installed, outside and inside unit, 7/22/2008. Motor started to buzz last week, 8/14/2014, and died. Motor module burned up, $500.00 to repair???? Thought I had a 10 year warranty. Payne's own press release dated 2/28/2008 states a 10 warranty. They stated it was onlyContacted them a second time. They stated those units used r-22 instead of r-410a refrigerant, so I was out of luck. trying to get a refund. Stay away from those units. They will not accept blame for a crappy product! I've had my Payne unit for 6 years and it's been fairly reliable. two service calls with in the first year and a half.
