We had Duvall out this morning Aug 1st...big mistake.
Our downstairs air conditioner went out, when the 2 techs arrived they checked the compressor, they said it had continuity, so they went ahead and replaced contacts and wiring, still didn't work.
They then said they would have to go and buy a fan motor, which after a while they came back and installed, and they said our cost would be around $500, but once again nothing worked. Then they apparently checked the compressor again, at which time they said the compressor was not working ( funny how there was continuity earlier)
Then they said we need a complete air conditioner system and it would cost us $11,200.00!
So obviously we are not going to have them install a new air conditioning system, as we had to pay $520.00 for the work they did, so we now have a brand new fan motor on a non working air conditioner. I would like to see if this company would give us our money back on the fan motor, as it appears that their original assessment on the compressor was completely wrong.
I will also be adding this review to Google, Nextdoor and others, so hopefully people will not have to pay for things that will not be used
Also, Duvall charges 4% when using a credit card! The company we are using that will be coming out tomorrow does not charge a c/c fee. DO NOT USE THIS COMPANY. As of Aug 3rd, I know the owner has read my complaint and totally ignored it (as he had responded to another review right after mine that was complimentary) I think this company is scamming customers by adding on extra costs, such as charging us for new fan motor, that was not needed.
