Long hold times. They show "in stock" items they don't actually have (item status updates AFTER you pay). They backordered a California-spec furnace when I needed a 49-state furnace which delayed my order by weeks until I spotted their error. Then they sold me an A/C-only TXV for a heat pump system (incompatible) and the evaporator coil they set me up with is not approved by the mfr for use with the condenser ordered. They realized this when I asked to return the TXV. They didn't offer to sell me the filter rack, filter-drier, duct board plenums, foil tape, or refrigerant lines I ended up needing to buy separately. Now, they want me to tear out the carefully-fitted cased coil, redo the flexduct and lines cut and brazed to fit, they can't promise when they'll ship the correct, different-size cased coil, AND they want me to pay a $200 summer price premium on the correct parts for my order from six weeks ago! Asked to make it right, they just said "sorry". They want me to pay up front for the replacement parts BEFORE I see the RMA terms. Wondering if I'm going to discover that that the mounted (but not yet connected coil) needs to be returned without the screw holes used to mount it. Maybe that's why they've promised THREE times to send me the RMA information I still don't have yet. Then I'll be out even more money. Saving money with ACWholesalers is getting to be very expensive.
