Systems common in Libertyville
Libertyville's housing stock shapes the kind of work we do. We regularly service and replace Pre-war boilers and radiators, 1990s-2000s forced-air systems, Central AC, 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 Libertyville homes plan replacements early
Libertyville splits cleanly in two for heating work. The older streets around the downtown and Copeland Manor are pre-war and interwar houses, many still on hot-water or steam boilers with radiators, where the real question is whether to modernize the boiler or take on the much larger job of converting to forced air. West and south of there, the 1990s and 2000s subdivisions run original forced-air furnaces and condensers now hitting their first full replacement at once - matched changeouts where the AC is the same age as the furnace, and replacing one alone leaves an unmatched system running below both units and their published ratings.

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.
