Existing system first
A furnace + AC, heat pump + air handler, heat pump + furnace, and AC-only installation do not share the same component or labor scope.
HVAC REPLACEMENT / GREATER BOSTON
Compare complete HVAC replacement options for your home.
The useful question is not “what does the box cost?” It is which matched system fits the existing equipment, access, venting, condensate, ducts, electrical conditions, comfort goal, and budget priority—and what that complete installation is likely to cost.

01 / THE USEFUL PART
What matters before anyone quotes the work.
Matched package
Outdoor unit, coil, furnace or air handler, controls, and required accessories must be stored and proposed as compatible combinations.
Installed price
Equipment, standard materials, labor, access, venting, drains, electrical and duct allowances, disposal, permit assumptions, and margin belong together.
02 / SYSTEM BRIEF
Build the range from the system you already have
The System Check offers a broad result early. Each additional answer narrows an assumption or reveals a real cost driver.

03 / COST & SCOPE
Why a responsible price is a range first.
Standard access
Basement, upflow, ground-mounted outdoor equipment, and reusable ducts are a different labor case from attic, roof, or restricted access.
Efficiency conversion
Moving an 80% furnace to 90%+ adds approved venting and condensate scope; a heat-pump upgrade adds electrical and control verification.
Confidence level
Unknown details widen the range. Model labels and installation photos can increase confidence but do not replace final site verification.
A complete proposal accounts for equipment, standard materials, labor, installation configuration, access, required accessories, allowances, disposal and permit assumptions. A site review confirms the final scope.
04 / STRAIGHT ANSWERS
Before you decide.
No contact form is required to read these answers or use the System Check.
01Does the Builder size equipment from square footage?+
No. Served area is a sanity check. Existing capacity is a starting point, and final sizing is verified before installation.
02Can I compare value, performance, and heat-pump options?+
Yes, when the existing configuration supports those paths. HVAC PM focuses on Goodman value, Carrier performance and higher efficiency, and Bosch inverter or dual-fuel options.
03Is the preliminary range a fixed quote?+
No. Sizing, matched compatibility, availability, access, and final scope are verified before a fixed-price proposal.
USE THE SITE AS A TOOL
Get the plan first. Decide what to send second.
The System Check can return a broad result early, then narrow it with equipment, installation, venting, condensate, access, and optional photos.
