Furnace Replacement for Long Grove homes
In a Long Grove home, the furnaces are frequently mismatched in age and capacity across zones, one replaced during a renovation, another original. We map how the zones perform, run a load calculation for each, and right-size every unit so a sprawling home heats evenly. On propane properties, we select equipment configured for propane rather than assuming natural gas, since the fuel affects the unit and its setup.
High-efficiency condensing furnaces suit most of these homes, and they need careful PVC venting and condensate handling across a larger floor plan. Licensed, insured installers coordinate the changeouts to keep an occupied home comfortable, route venting to code, and confirm safe combustion. The old equipment leaves with them, every warranty is registered, and we hand off any Nicor rebate the new equipment qualifies for.
