We have installed this high efficiency Trane hot air furnace in combination with a Trane air conditioning coil and condenser. These units are able to further extract the heat from gas combustion than their traditional counterparts, thus lowering monthly heating bills. In addition customer also received a rebate from O&R for a new high efficiency furnace installation. This was a winning situation for all parties. Customer has lower heating bill, and lowered their out of pocket costs and we get to show off our craft and do what we love. As always, if you have questions about how high efficiency heating can benefit you, please call us.
