    System went down on the 10 year anniversary, What to do?

    Bryant Evolution 5 ton communicating system in south FL house. Unit stopped cooling on 3/28 at night. I called the AC company that installed it (with whom we had a 10 year extended labor contract) on Sunday 3/29 and they said a tech will be over on Monday morning 3/30. Sunday night I pulled out our paperwork only to find that our install date was 3/29/2010. They said that they should be able to honor the warranty since we contacted them on that date.

    Tech found the evaporator coil frozen with ice and said it's shot and recommended replacing the entire system. He set the tstat at 77 degrees and another tech came out 48 hrs later which was this am. The ice was gone and he pressure checked the system and could not find a leak but said the evap coil was in pretty bad shape. He added leak stopper to the system and told me to use the system as we usually do and if it freezes up again then we'd have to do other tests to determine if there's some sort of restriction somewhere in the system. He had their parts guy contact the Bryant distributor who said they would give them a new evaporator coil but if the old one didn't have a leak they would charge for the new one, which is roughly $900, which would be passed onto us.

    The condenser unit has been problem free for 10 years as has the entire system up to now. We have it serviced every 6 months and always changed the filter regularly. We have 3 zones in our home and each system has lasted between 9 and 14 years. The original 5 ton installed by the builder lasted 9 years and was problematic from early on. A load calculation and duct leak test were done when the Bryant system was installed and a 5 ton system is indicated.

    If an evaporator leak is found very soon, the parts and labor will probably be covered under warranty. Or would you recommend getting a new system? A new system will be somewhere between $6500 and $8500 depending on what equipment we choose. With 0% financing for multiple years available, the cost would not be a problem.

    Sounds like a bunch of sales techs.
    A new system at 10 years old because there’s ice on the coil? No.
    Ask them to give you an accurate diagnosis first before the sales pitch starts.

    Right now it is working well after getting a slight charge of coolant with leak stopper.

    So if there is no evaporator leak, the thermostat is working well, the filter is almost new and is clean, the condensate line is clear, and the fan blower is working well, is there another reason why the evaporator coil freezes up?

    “ is there another reason why the evaporator coil freezes up”

    Dirty indoor coil is one. I know you mentioned you have it serviced every 6 month, but in those 10 years any invoice say they cleaned or check inlet side of coil?


    “ He had their parts guy contact the Bryant distributor who said they would give them a new evaporator coil but if the old one didn't have a leak they would charge for the new one, which is roughly $900, which would be passed onto us. “

    Why should you be on the hook for a misdiagnosis from this Contractor, if they replace the coil without proof of a leak.


    “but said the evap coil was in pretty bad shape.”

    It’s not unusual to see a rusted indoor coil , as the support frame is usually made of steel. Discoloration of copper is normal also when it ages.

    The first guy said he added 3 lbs, the second said he added very little but didn't give a number.
