- What is the average coil life?
- If coil fails, then I will be required to replace both coil and condensor (as R22 will be phased out in 2010) and probably coils using R22 will not be avilable in the market?
- The condenser using R22 can not be retrofit with coil using R410A?
- He is providing 5 years warranty (cost $209.0) on "Parts and Labor", is it worth to take it?

Condenser using R22 can be retrofit with coil using R410A?
I am planning to replace the furnace. The technician from Trane is advising me to replace both furnace and coil as the coil was installed when original heating and cooling system was installed back in 1972 when it built. Last year, I replaced the condenser (with Trane high efficiency condensor). This condenser uses R22. Reason he is siting to replace the coil is if coil fails down the road more that likely I won’t be able to get a replacement, then the only option would be to replace both the condenser and coil.

What is the average coil life?
There really is no average coil life except to say it is always smart to replace the indoor coil when replacing the outdoor unit. This is said more for energy savings than anything else since the SEER ratios change every so many years for the better. If coil fails, then I will be required to replace both coil and condensor (as R22 will be phased out in 2010) and probably coils using R22 will not be avilable in the market? NO a R-410A rated coil will be able to be used on a R-22 system with no problem so you will be able to replace your old coil in the future without replacing the outside unit. The condenser using R22 can not be retrofit with coil using R410A? You cannot use R-410A refrigerant in a R-22 unit. No retrofit is possible due to design pressure limitations. But you can use a R-410A inside coil on a R-22 outside unit since the R-410A coil is rated for a higher pressure operation than R-22 will expose it to. He is providing 5 years warranty (cost $209.0) on "Parts and Labor", is it worth to take it? Is this on the replacement furnace? If so the parts are probably guaranteed for 5 years to start with but the labor warranty seem to be worth it if you feel he will be in business for 5 years. Read the factory warranty and then decide. |

I have several proposals for the installation of a new, more energy efficient HVAC system for my home. The company reps from Trane are telling me that they will need to install new refrigerant lines for the R410A because they can't remove all traces of R22 from the current lines. Lennox reps say...

My home AC unit is not cooling. I thought the compressor was not working, I had the capacitor checked out and it is good, I cleaned the contacts and when I reinstalled it and turned the system on I discovered a small hole on the coil, since the line is not charged (all freon leaked out) I couldn't...

Hi All, Here is my issue. Recently, our home warranty company paid to replace a 25 year old 7 SEER Borg Warner outside unit, but swore up and down that the indoor Borg Warner Coil would be OK with the new 10 SEER Carrier. We no longer have this home warranty company and they are not standing...
