    Hvac repair quote for failed compressor which grew into replacement of entire system

    Hello,

    My 14 y/o Carrier Infinity condenser stopped working recently. HVAC technician assessed and showed me how mice had chewed away wires to compressor right at entrance into that part so could not be rewired (there was obvious activity from mice in the condenser). HVAC company said it would cost about as much to replace the entire condenser as replacing the compressor so he gave me an initial quote for repair which said: "replace condenser unit S#0437 with one Bryant M# 113ANA036." I scheduled the work and I was told they would order the parts. However, a couple of weeks later I was strangely re-quoted by email for an entire system- complete condenser and air-handler. I called HVAC company and spoke with the owner who said his guy made a mistake because the Bryant condenser he quoted me would not be compatible with the Carrier Infinity System secondary to the computerized communications between the Infinity condenser, air-handler, and thermostat/control unit. He said pricing a new replacement Carrier Infinity condenser would be as expensive as getting a entire new non-Infinity system and so he quoted me an entire new 13 SEER non-Infinity system (which he noted would give me a 10 year warranty). So this job to replace a failed compressor has grown to replacing the condenser to replacing the entire system (condenser/air-handler/controller) with a very large price tag.

    Needless to say, I am not happy that a failing compressor replacement has somehow morphed into replacement of an entire system with a huge price tag. With his acknowledgement that he could not replace the Carrier Infinity condenser alone, I am not sure why he did not simply offer me repair of the Infinity condenser by replacing the compressor. That would seem to be the most cost-effective solution. I do not expect to be in this home more than another three years (which I told him) and so I do not want to invest more than I have to into this repair.

    From the sticker on my Carrier Infinity condenser, the model number is 24ANA736A300.

    Before I contact my HVAC company and ask him about replacing the compressor alone, I would like to know what other professionals think about this and is there anything I am missing or should consider. Is there another condenser unit for less money that is compatible with the Carrier Infinity system? Is replacing the compressor alone the best way to go? Does this HVAC company's quotes and their rationale seem reasonable? Is this just a classic upsell?

    Thank you.

    Call a different company for a second opinion.

    I started doing this in 1982. I have never seen a compressor where you could not install new wires. In fact, it is not uncommon for those wires to overheat or burn, in which case they get replaced. Second opinion is essential in this case.

    Depending on where you are, and how many HVAC contractors are in your area, you could even call the same company back and ask for the owner, or at a minimum their senior tech, to come out and explain why the wires cannot be replaced. Any reputable contractor will make good on a "bad diagnoses" from a new tech starting out. Depending on what they say or how they treat you, you may still want that second opinion.

    I do a triple evac with nitro to remove non condensables.

    I'm feelin' a little peculiar.

    Was he talking about the wiring harness? Any pictures?

    Are you trying to say if you buy that compressor new, it already has wires attached which cannot be replaced?

    No not really, I've never replaced one.
    It looks like a standard plug on the internet.

    Rookie probably not familiar with those plugs, LOL.

    Probably has an install background trying to break into service.

    I think the only time I've seen wires coming out of a compressor is on a very old Westinghouse compressor from the '60s

    See photos below. This is a photo of the compressor inside of the condenser unit. The wires involved are the two black wires which go to the bottom of the compressor. One chewed off completely other partially.

    That is a crank case heater to keep the oil warm. Although it is a device to protect the compressor, if the compressor is not running, it is likely there is another problem.

    You DEFINITELY had a rookie service tech look at your unit !!

    Correct, misdiagnosed. Should have been isolated for testing.
    Find a different tech.

    By the way, that heater should be a replacement part it sits in a well.

    Everything I am seeing and what you are sounds like at most you need a plug type CCH and a wire harness. Not going to say it is cheap but it should be much cheaper than a compressor.

    So I've heard two theories why mice chew wire.
    #1 the insulation is manufacturer with peanut oil.
    #2 they sharpen their teeth on it.

    Did it trip the breaker, or you noticed your residence not getting as cold as it use to ( compressor and fan motor running ) is that why you called for service or is the A/C running and not cooling? They make universal crankcase heaters that strap on to the belly also.

    A chewed up wire(s) feeding the non functioning CCH is not going to fix a A/C compressor and outdoor and indoor fan motor that is running.

    Yeah, not likely going to get that original CCH out.

    To the original poster . . . That compressor might be bad, but you need a qualified tech to inspect, troubleshoot, and verify what is really going on.

    It's only ceramic and epoxy in a steel well guess what I would do ?
    Of course a belly band would work just as well.
