Legitimate costs replacing A/C system?
I'm a new home owner in central California needing to replace an existing A/C unit. It's a split system, 3 ton, compressor is on the ground. I'm forced to deal with a contractor selected by the home warranty insurance co. - the policy came with the house. There are noncovered costs that I would like to make sure are legitimate.
They wanted to charge $200 for disposal of the old unit and reclaiming the coolant. Since it was totally empty of coolant, I had it removed by a pro for $0 who made his money from recycling it. Now the contractor wants to charge $300 for "flushing the system."
They want $400 for "duct modification." When I asked them what that included, they said they subcontract to have the ducts pressure tested, and any needed "modifications" based on the testing would be additional charges.
I get the sense that they are breaking out individual parts of the job and itemizing as separate charges. I'm wondering if there will be a charge for maybe "removing unit from our truck and transporting it to the backyard" or something.
I'd appreciate any thoughts on how confident I should be with these charges. Thanks!
