I’m telling you do not use AJ Perry. They soaked us pretty good and I’ve had 2 companies come in to fix what they did since. Last week I had my new company come in and address a leak from the new heater stack. Guy told me there was no sealing at all, he even asked before I told him was this AJ Perry? Every HVAC person I talk all say the same thing. Overcharges & poor workmanship
