We regularly service and replace Zoned two-furnace systems, 1990s-2000s forced-air, Propane furnaces on outlying lots, High-efficiency furnaces, Heat pumps across this area. Each calls for a different approach - boilers and steam systems differ from forced-air furnaces, and older homes often need careful venting and duct work.
Why Hawthorn Woods homes plan replacements early
Hawthorn Woods is two building eras sharing a zip code. The older half is 1970s and 80s custom houses on half-acre-plus wooded lots, several of them off the gas main and running propane, where the efficiency math is different enough that a heat pump is a real answer rather than a pitch. The newer half is the Country Club development and the subdivisions around it - large 1990s and 2000s homes built with two zoned furnace-and-condenser systems that were installed the same week and are now aging out together. Replacing the upstairs zone and leaving the downstairs one is how a homeowner ends up doing this job twice, and on these floor plans the upper zone is always the one that fails first because it carries the whole cooling load.

Should I repair or replace my system?
As a rule of thumb, if a system is 15+ years old, needs a repair that costs more than about a third of a new unit, or has failed more than once in a season, replacement usually saves money over time. We give an honest recommendation - if a repair makes more sense, we'll say so, and we'll do the repair.
Do you do repairs, or only replacements?
Both. We repair furnaces, air conditioners, and boilers, with a $99-$169 diagnostic that is credited toward the repair and a flat repair price you approve in writing before any work starts. Most repairs run $180-$950 depending on the equipment and the fault. Replacement is what we specialize in, but that does not mean we push it - a good system with a failed part gets the part.
Do you offer a maintenance plan or service agreement?
Yes. Plans run $199-$399 per year depending on tier and how many systems the home has, and cover two seasonal visits - heating in the fall, cooling in the spring - plus priority dispatch and a discounted repair rate for members. A one-off tune-up without a plan is $129-$199. Most manufacturer warranties require documented annual maintenance, so a plan also keeps that coverage intact.
