If I could give them a zero I would. Never let them come to your house for a home warrarnty service call. They advised us the 12 year old air conditioning unit on our house was inproperly installed when the condensation line was actually leaking into our house. Even thought the A/C was installed to CODE. Not only causing the warrently company to deny our claim but also voito Exclude any future work to our unit. Luckliy my husband is a tradesman and told the warrently company it could not possibly be to that considering the age of the unit and there has never been prior damage to the walls. A second company came out, confirmed the lines were clogged and also that the lines for primary and secondary drainage needed to be switched. He corrected and called the Insruance comapny so we should be able to get other items covered in the future. I think A-Quality is getting paid extra to exclude the A/C from your home warratnty's THEY SUCK!
