About HVAC Installation & Replacement
A new HVAC installation or replacement covers the full comfort system: the furnace or air handler, the air conditioner or heat pump, the evaporator coil, the thermostat, and the connections that tie them to your ductwork, gas, and electrical service. A replacement is the right call when a system is 12-15+ years old, needs a major repair like a compressor or heat exchanger, or can no longer hold an even temperature efficiently.
AMW starts every installation with a Manual J load calculation so the equipment is matched to your square footage, insulation, window load, and layout. An oversized system short-cycles, runs up your bills, and leaves rooms humid; an undersized one never catches up on the coldest and hottest days. Right-sizing is the single biggest factor in how comfortable and efficient your new system will be, and it is the step budget installers skip.
We install high-efficiency furnaces, central air conditioners, and heat pumps from trusted manufacturers, and as a Mitsubishi Diamond Contractor we also design ducted and ductless inverter systems that deliver exceptional efficiency in North Shore homes.

Frequently Asked Questions
A standard furnace-and-AC changeout is usually completed in one day. Adding ductwork, a heat pump, or zoning can extend the job to two days. We give you a clear timeline in your written quote.
As a rule of thumb, if your system is over 12-15 years old, the repair costs more than a third of a new system, or it needs a major component like a compressor or heat exchanger, replacement is usually the better long-term value. We will give you an honest recommendation either way.
It depends on square footage, insulation, windows, and layout, not just a square-foot rule of thumb. We perform a Manual J load calculation on every installation so your system is sized correctly for comfort and efficiency.
Yes. We offer financing options on qualifying installations so you can move forward with a high-efficiency system without paying the full amount up front. Ask us about current promotions when you call.
A correctly sized, modern high-efficiency system can meaningfully reduce energy use compared with a 15-year-old unit, especially inverter-driven equipment. Actual savings depend on your home, usage, and the system you choose, we will give you realistic expectations, not inflated promises.
