Customer Question
I have an Infinity...

I have an Infinity system that I have had for 11 years 3 ton 16 seer model 25HNA636A300 serial 2106E31593 I have been told the compressor has gone bad. My question is on repair. Carrier sent out a dealer bulletin in 2014 for repair and or a replacement. The replacement model is still in use today. Is there any reason I can't just replace the pump with the replacement recommended in that bulletin. Why am i being pushed to replace everything? Also on repair is their a specific carrier model number for the compressor.

Contractor's Assistant: I'll do all I can to help. How long have you been dealing with this?

Last month reiceived a system failure on 12/13

Contractor's Assistant: Do you plan on doing the work yourself?

No

Contractor's Assistant: Anything else we should know to help you best?

I am trying to make the best decision on replacement /repair. I feel my quotes are extremely high

Hello, 11 years ago they used a different refrigerant than is use today, they used R-22... since then the industry has moved to R-410a, and R-22 has been declared illegal to use in the US.

That is why they recommend an entire system replacement, the two refrigerants are not compatible nor are the controls.

.

Having said that, if there is still one of the replacement units mentioned in the dealer bulletin from 2014, it would certainly work as a replacement....The refrigerant however would most like have to be switched from R22 to one of the R22 replacements such as R22a, which is not quite as efficient as R22.

.

We can go from here, without any time limits and in as much depth as you like.

My goal is to give you the best experience possible! I hope I have earned a 5 star rating! Please remember to rate my service by selecting the 5 stars at the top of the screen before you leave today. If you need more assistance, please use the reply box and let me know.
