HVAC Contractor

If you’re not sure yet whether you need a repair, a new system, or a whole different approach to heating and cooling your house, that’s exactly the conversation to have before hiring anyone. Powers Air is an owner-operated HVAC contractor based in Granby, and when you call, you get Drew Powers, not a dispatcher reading from a list of available techs. He sizes the job, he’s usually the one doing it, and he brings in a trusted network of licensed subcontractors for the pieces outside his own trade, like plumbing. Nothing gets handed off to a stranger without you knowing it.

What HVAC Contractor Involves

An HVAC contractor is the person or company responsible for the heating, cooling, and air handling systems in a home or commercial building, from the first assessment through installation, permitting, and the service calls that come after. For Powers Air, that scope covers residential and commercial work across a specific set of trades, all handled by the same operation rather than split across a chain of subcontractors.

Ductless mini-splits and heat pumps, which is where we spend most of our time and the equipment we know best
Central air conditioning, including repair, replacement, and new installation
Furnaces, oil, propane, and gas, including repair and replacement
Ductwork design, repair, and modification for both new and existing systems
Ventilation, including fresh air systems and exhaust for tighter, more efficient homes
Electrical panel upgrades and change-outs, performed in house under
EV charger installation, also performed in house rather than referred to a separate electrician

The reason those last two are on this list at all is that heating and cooling projects run into electrical capacity constantly. A heat pump conversion, a new furnace with a variable-speed blower, or central air added to a house that’s never had it can all bump up against an old panel that wasn’t built for the load. Handling that under one roof means one contractor responsible for the whole job, not a heating contractor pointing you toward an electrician who has to be scheduled separately and coordinated by you.

When It Is the Right Answer and When It Is Not

Not every job needs a full-service contractor, and it’s worth being honest about that instead of pretending every call has to go through a big conversation.

A full-service HVAC contractor is the right call when:

You're not sure yet whether the answer is a repair, a replacement, or a different type of system entirely, and you want that assessed honestly before committing to anything
The project touches more than one trade, for example a heat pump install that also needs a panel upgrade, or a furnace replacement that uncovers a ductwork problem
You're planning a larger project, like converting from oil heat to a heat pump system, adding central air to a house that's never had it, or outfitting a house for an EV charger alongside other electrical work
You want one person accountable for sizing, permitting, and the actual installation, rather than managing multiple contractors yourself

It’s worth calling a more specific service line, or being direct about the narrower job, when:

You already know exactly what's wrong, for example a mini-split that's stopped cooling or a furnace that won't ignite, in which case the repair pages for that specific equipment will get you a faster, more targeted answer
The job is purely plumbing, which Powers Air doesn't perform directly. We coordinate that through a trusted subcontractor when it's part of a larger project, but a standalone plumbing issue is better served by calling a plumber directly
You need a manufacturer certification, a specific brand relationship, or a warranty registration Powers Air hasn't confirmed. We won't claim a certification we don't have, and we'll tell you plainly if that matters for your situation

Drew would rather point you to the right narrower service, or tell you the job is smaller than it sounds, than turn a simple call into a bigger contract than the house needs.

How We Size and Specify

Every trade under this roof gets sized the same way: based on the actual house, not a rule of thumb. For heating and cooling equipment, that starts with a Manual J load calculation, which accounts for square footage, insulation, window count and orientation, ceiling height, and how the specific house holds or loses heat. That number, not the size of whatever’s currently installed, determines equipment sizing. Oversizing is the most common mistake in this industry, and it doesn’t make a house more comfortable. An oversized system cools or heats the air fast, shuts off, and short cycles instead of running a longer, steadier cycle that actually controls temperature and humidity evenly.

For heat pumps specifically, sizing includes checking cold-climate ratings and HSPF2 performance, since capacity drops as outdoor temperature drops, and deciding whether backup or auxiliary heat is needed to cover the coldest stretches of a Massachusetts winter. For furnaces, it means checking AFUE ratings and static pressure in any existing ductwork before assuming new equipment can run through it. For electrical work, sizing means an honest load calculation for the panel itself, factoring in what’s already on it and what new equipment, a heat pump, an EV charger, a new furnace blower, will add, rather than assuming the existing panel has room simply because it hasn’t tripped yet.

Equipment and What Actually Differs Between Systems

Across this many trades, the differences that matter aren’t always obvious from a spec sheet or a showroom.

Ductless mini-splits work in homes with no ductwork at all, which describes a lot of the older housing stock in this territory, especially homes with steam or hot water radiators. Central air and standard furnaces need ductwork to function, ductless doesn't
A large part of this territory has no natural gas distribution, so furnace decisions here usually come down to oil versus propane versus a heat pump, not a simple gas upgrade like you'd see closer to Boston
Heat pumps handle both heating and cooling through one system, while a furnace-plus-air-conditioner setup is two separate systems doing one job each
Panel capacity is a real, physical limit, not just a number on a label. A 100-amp panel that's already near capacity can't safely take on a heat pump and an EV charger without either an upgrade or a load management strategy
EV charger installation depends heavily on where the vehicle actually parks and how far that is from the panel, which is a bigger factor in cost and feasibility than the charger itself
Commercial HVAC work often involves different equipment classes and code requirements than residential, and the assessment starts from the building's use, not a residential template

We match equipment and scope to the house or building in front of us, not to whichever line is easiest to sell that week.

What the Work Looks Like Start to Finish

You call, and we start with a real conversation about what’s happening or what you’re trying to accomplish, not a script.

For anything beyond a straightforward repair, we come out, assess the house or building, and run the calculations that matter, load, static pressure, panel capacity, whatever the project touches. We’ll walk you through what we find in plain language, including any trade-offs, before quoting anything.

If the project moves forward, we schedule it. Work performed directly by Powers Air, HVAC installation, ductwork, electrical panel work, EV charger installation, is done by Drew and handled in house from start to finish. Plumbing tied to a larger project is coordinated through a trusted, licensed subcontractor. Every job that requires a permit gets one, and every inspection that’s required happens. Once the work is done, we test the system under real conditions, not just a quick power-on, before calling it finished, and we clean up after ourselves.

What it costs

There’s no single number that makes sense across ductless installs, furnace replacements, panel upgrades, and EV chargers, so we won’t pretend otherwise here.

Which trade or combination of trades the project touches
The size and complexity of the load calculation, whether that's BTUs for a heating and cooling system or amps for an electrical panel
The condition of what's already in place, existing ductwork, an aging panel, old wiring
Whether the project needs coordination across more than one trade, such as HVAC and electrical together
Permit and inspection requirements for your specific town

You’ll get a real quote after we’ve actually looked at the property, not a range pulled off a website before anyone’s seen the job.

Rebates and Incentives

Massachusetts runs the Mass Save program, and it’s worth understanding as part of planning a heating, cooling, or electrical project, since incentives can apply to certain qualifying equipment. What applies depends on your specific equipment, your utility, and the details of the project, so we’ll help you work through what might apply as part of the conversation rather than promising a figure upfront that may not hold once the specifics are in.

frequently asked questions

What's the difference between an HVAC contractor and an HVAC technician?

A technician typically handles a specific repair or service call. A contractor is responsible for the whole job, sizing, permitting, coordinating any other trades involved, and the installation itself. Powers Air operates as a contractor, with Drew personally involved in the sizing and the work, not just dispatching a technician.

Do you handle both residential and commercial work?

Yes. The assessment and equipment differ between the two, since commercial buildings often have different load profiles and code requirements, but both fall under the same contractor relationship.

Is the electrical work actually done by Powers Air, or referred to another company?

It’s done in house. Panel upgrades and EV charger installation are performed by us under our electrical licensing, not handed off to a separate electrician you have to schedule and manage yourself. It’s permitted and inspected the same as any other job.

Do you do plumbing?

Not directly. Plumbing tied to a larger HVAC or electrical project is coordinated through a trusted, licensed subcontractor we’ve worked with. A standalone plumbing issue with no HVAC or electrical component is better handled by calling a plumber directly.

My house has no ductwork. Can you still help?

Yes, and it’s one of the most common situations in this territory. A lot of the older housing stock, especially homes with steam or hot water radiators, was never built with ductwork. Ductless mini-splits, sometimes paired with a heat pump, are usually the practical answer rather than adding ductwork to a house that was never designed for it.

How do you decide what size system or panel a house needs?

With real calculations, not a rule of thumb based on square footage alone. Heating and cooling equipment gets sized with a Manual J load calculation. Electrical panels get sized based on existing load plus whatever new equipment is going in. Oversizing or undersizing either one causes real problems down the line, so we don’t skip this step.

Are rebates available for the work you do?

Massachusetts offers incentives through the Mass Save program, mainly around qualifying heating and cooling equipment. Whether anything applies to your project depends on the specifics, so we’ll go over that with you once we know what you’re working with.

How fast can you get out to look at a project?

Call 413-339-3194 and we’ll give you a real answer based on the day’s schedule and what the project involves. No-heat and no-cooling calls during peak season get priority.
