About 90 days ago my furnace went out. I was told $4700 for it,then told getting a new furnace required a new return, & ended up having to pay $5700. Since then I've called them back out 3 times. The 1st & 2nd times were both due to wiring not done correctly when the furnace was installed. The 3rd time was today, the Tech didn't get here till after 5:15 p.m. He 1st said the outside Unit was knocked out by the storm last night. I told him No it wasn't it had been working fine till late afternoon. 2nd Tech said another part was out he thought. 3rd He said no freon & checked with his thing that detected a leak he said, that it didn't have any freon because the coil had a leak. He then refused to fix it, due to the age of the Unit, said it wouldn't due to the age of the Unit, wanted me to buy a new one for several thousand more. At that point I asked him was he refusing the repair, he said again not worth it due to age of Unit (which is old). At that time I told him "Bye", & had him leave. I called another company who came out(due to the late hour by this time, it cost me an $89 fee, but they fixed it. We gave them the diagnosis the John Moore Tech had said coil had a leak, & leaked out freon. So they put a Stop Leakin the coil,, & it wasn't the coilleaking, the copper had a leak which they welded.All this ended up costing me $1000. The stop leak was $229 & unnecessary due to the incorrectdiagnosisby the John Moore Tech, plusthe $*( trip fee because of the late hour. So the John Moore Tech cost me a total of $318.00 , that could've definitely been avoided. I WILL NEVER USE JOHN MOORE AGAIN, & WOULD STRONGLY ENCOURAGE ANYONE ELSE TO BE EXTREMELY CAREFULIF YOU HAVE TO USE THEM.
