HVAC Contractor in Amherst, MA

Walk into a house near the town center and you’re as likely to find cast iron radiators fed by an oil-fired boiler as anything with a duct in it. Ten minutes away in the newer neighborhoods, the story flips to forced-air furnaces from the 1990s paired with a central air unit that was never quite right for the load. Both situations call for real specification work, not a standard package pulled off a truck.

Powers Air handles the full range under one roof: ductless mini-split and heat pump installation, central air conditioning, furnace replacement, ductwork and ventilation, and licensed electrical panel upgrades and EV charger installation done in-house rather than handed off to a subcontractor. Drew Powers runs the job himself, backed by a trusted network of plumbing and electrical subs where the work calls for it, so the person who runs your load calculation is the same person standing in your basement.

What Amherst homes are working with

A good share of the housing inside walking distance of downtown predates ductwork entirely. Steam and hot water radiators are original equipment in many of these houses, and retrofitting a duct system into plaster walls and low ceilings rarely pencils out. That’s exactly the case ductless mini-splits were built for: individual wall or ceiling-mounted heads, one per room or zone, connected to an outdoor unit through a small refrigerant line set that runs through a hole a few inches wide instead of a duct chase.

The buyer profile changes because of the university. A meaningful share of housing near campus is owned by landlords and property managers running single-family homes that were split into two, three, or more units over the decades, sometimes with one boiler still trying to heat all of them. That calls for a different kind of specification: separate zones with separate thermostats so one tenant isn’t paying to heat another tenant’s apartment, equipment that can be serviced without entering every unit, and a plan for buildings with no natural gas line, where the fuel today is oil or propane delivered by truck. Owner-occupiers in the outlying parts of town are usually a simpler job: one house, one system, often an older forced-air furnace being weighed against a heat pump for the first time.

How we size and specify the system

Every quote starts with a load calculation, not a tape measure and a guess based on square footage. ACCA Manual J accounts for insulation levels, window area and orientation, air leakage, and ceiling height to figure out how much heating and cooling capacity a specific room actually needs. Skip that step and the fallback is rule-of-thumb sizing, which almost always errs toward too much equipment rather than too little. Oversizing is the most common mistake in this industry, and it makes a house less comfortable, not more. An oversized system satisfies the thermostat fast, shuts off, and starts again a few minutes later. Short cycles like that mean the system never runs long enough to dehumidify properly in summer or hold a steady temperature in winter, and the compressor wears against a harder duty cycle than it was designed for.

A quote from us should give you enough to actually evaluate it:

A room-by-room load calculation, not a flat square-footage number
Specific equipment model numbers, not just "a 2-ton system"
Line set lengths and routing
Confirmation the electrical service has capacity, or what it will take if it doesn't
Permit and inspection included, not an add-on
A written price, not a verbal estimate

A bid that skips the load calculation and jumps straight to a price is a warning sign, not a bargain. It usually means the number was picked to win the job, not sized to the house.

What the work involves

Site visit and load calculation
Written proposal with equipment, zones, and price
Permit filed with the town
Installation, typically one to three days depending on scope
Commissioning and system check, including refrigerant charge verification
Inspection and walkthrough

When a job needs more electrical capacity than the existing panel has, whether for a heat pump’s new circuit or an EV charger, that work is done by the same crew as licensed, permitted, in-house electrical work rather than coordinated with an outside electrician on a separate schedule.

What it costs

Ductless mini-split systems typically run from the lower end to the higher end installed for a single zone, with each additional zone adding to that. Central air conditioning, furnace replacement, and multi-zone heat pump systems fall into a wider range depending on the scope of the job. What actually moves the number: how many zones the house needs, whether the indoor units are wall-mounted, ducted cassettes, or floor-mounted, how far the line sets have to run, whether the electrical panel has room for new circuits or needs work first, and how easy the equipment is to access.

We won’t give you a number worth trusting until we’ve seen the house and run the load calculation. Every quote from Powers Air is written, not verbal, and it’s a price, not a placeholder for change orders once the crew shows up.

Permits and Inspection

Mass Save offers rebate and incentive programs for qualifying heat pump installations, and the amounts and eligibility rules change over time. Rather than quote a figure that may be out of date by the time you read this, we’ll walk through what currently applies to your specific house and equipment during your estimate.

frequently asked questions

Do you work on houses with radiators and no ductwork?

Yes. That’s exactly the situation ductless mini-splits were designed for. Each indoor unit is its own zone, connected to an outdoor condenser through a small line set rather than a duct system, so there’s no need to open up walls or ceilings for ductwork that was never there.

Will a heat pump actually keep up in a Massachusetts winter?

Yes, a properly sized cold-climate heat pump can handle Massachusetts winters. We check low-temperature capacity ratings to ensure reliable heating for your home.

Do you handle multi-unit and rental properties?

Yes. We work with landlords and property managers on buildings that have been split into multiple units over the years, including specifying separate zones and thermostats so tenants aren’t sharing heating costs with each other.

Do you also do electrical panel upgrades and EV chargers?

Yes, as licensed in-house work rather than a referral to an outside electrician. If a heat pump or EV charger install needs more electrical capacity than the existing panel has, we handle that as part of the same job.

Am I eligible for Mass Save rebates?

Eligibility and rebate amounts change and depend on the specific equipment and household, so we walk through what currently applies during your estimate rather than quote a number that might be out of date.

How long does a typical install take?

Most single-family ductless or heat pump installs run one to three days depending on the number of zones and whether electrical work is needed. You’ll get a specific timeline in the written proposal.
