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.
