What the property adds to labor
A furnace or air handler set deep in a finished space, HOA notification requirements common in Troy subdivisions, an occupied home during the swap, and protecting finishes during access can each extend the timeline.
Spelling out the scope
Where the job's boundaries sit, the system's rated capacity, whether new materials are compatible with what's staying, and how testing and disposal get handled should be documented, not assumed.
Permits, HOA sign-off, and other trades
Troy treats HVAC, electrical, plumbing, and building permits separately, and many exterior projects also need homeowner-association approval — confirm exactly which apply before scheduling.
For planning only — not a quote
Every figure here is a planning reference, not an offer. Request a written, property-specific scope and price before authorizing work.
