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.
A standard furnace or AC replacement, or a furnace-and-AC changeout together, is usually done in one day. Adding ductwork, a heat pump, or zoning can stretch the job to two days.
Often it makes sense, but not always. The furnace blower and the AC coil work as a pair, so a new air conditioner on an old furnace may not perform the way it should, and replacing both at once is a single installation. If one of them is young and in good shape, replacing only the one that failed can be the better value. We can price it both ways, but when the system's age warrants it, we recommend replacing the whole system.
A fair quote is in writing and spells out the job: the equipment make and model, the efficiency ratings, how the size was figured (a load calculation, not a guess), what is included, such as the permit, removal of the old equipment, and any ductwork, gas, or electrical work, the warranty, and the total price. Be careful with a quote that only lists a size and a number, or that pushes you to sign today. Compare quotes line by line, not just the bottom line. When there are real options, we give good, better and best, and we look at repair first when it makes sense.
It is a quick rule of thumb: multiply the age of the system in years by the repair cost. If the result is more than $5,000, replacing is worth considering. Use it as a starting point, not a final answer, because it does not account for safety, efficiency, or how well the system has been maintained. We give you both prices, the repair and the replacement, so you can decide.
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.
