Ive used Convertible Air multiple times over the last decade, so when our 20+ year water heater bit the dust, we gave Convertible a call for a tankless model. They had the best price (just like they always seem to do) on the same make and model that other vendors were charging SIGNIFICANTLY more for.
During the install they didnt think they could vent the heater out the wall that we wanted it vented. When we said the venting location was important to us, they called the manufacturer and figured out a way to get it done.
Over the last decade Ive purchased a furnace, central air and combination tankless water heater & boiler for another home, all from Convertible Air. Ive never had any problems with anything theyve ever sold me and they are always helpful and informative when they come to do routine maintenance.
When its time for a new HVAC purchase, do yourself a favour and get a recommendation and a quote from Convertible Air, then shop around for comparison pricing. Id be shocked if anyone beat their price and they keep everything running like clockwork. So what else do you want from a vendor?!
