I've received a number of estimates from 5 contractors to replace both my furnace and ac. I'm inclined to use a410 and all but one quoted me for such a system. The one contractor quoted me an r-22 unit and said if I wanted the a410 he could do it but the price difference is $1000.
Is this a realistic number for a 5 ton ac with about 20 feet of line length?
Yea, its well with in reason.
I would say, look at the R22 bid, and get more bids on these while you can. Compare SEER rating as well.10,12 seers wont be available next year. Buy your AC this year. Next year eqip. prices will double. (Thanx to regs. good or bad) its the law.
All the bids have been for 13 SEER. I'm inclined towards A410 because after 2010 I'm assuming the price of R-22 will be higher than A410. Realistically, given I choose a quality installer, I won't have to worry about recharging the system on my dime until then... Is this a good assumption?
whatever gas you have in the system is prone to leak. puron operates at higher pressures. R22 is lower. The installer is your man here. Pressure is the bout. R22 will be available for several years. Do you want to pay for the cost up front is the question?
And yes, thats a good assumtion.
R-22 will still be manufactured for use in existing systems untill the year 2020, and there will be plenty to go around for servicing systems for years after that
Thanx mark beiser. see Im still learning , just not dead.
R 12 no go.
fat eddie. lets here from you now
HCFC PHASEOUT SCHEDULE

Now, this doesn't indicate what the manufacturers WILL/CAN charge for R-22 only that they can make it till 2030 if I read this right. :)
No production of 22 as of 2020.
Like r12, r22 will become more expensive.
I was under the understanding that what MikeJ printed out was not yet the 'law'.
It still had to be voted for or ratified or something, but as of yet, was not a certaintee ?????
Am I missing something, or does it seem like alot of people are scared of 410a. It was introduced over 5 years ago, and wouldnt have been put into use without extinsive testing. When inatslled properly, a 410a system has a LOW failure rate. The company I work for averages about 30 410a systems a year, and our customers are happy. Time to face the facts, R22 is going byebye, just like R12 did, it's only a matter of time. If I had my choice, I would use nothing but 410a. Just my opinion.
How is an r-410 system better than an R-22 system ????
