Commercial Electrical & HVAC Services

When something goes down at a Maine business — the power, the heat, the cooling — it isn’t an inconvenience, it’s lost revenue, unhappy customers, and staff standing around. MC Electric Comfort Systems keeps commercial buildings across Central Maine, the Kennebec Valley, and the Midcoast running, with one important difference from most contractors: we’re licensed for both electrical and HVAC. For a business, that means one team, one schedule, and one company accountable for keeping you open — not two vendors pointing fingers while your doors stay closed.

We’re a veteran-founded contractor licensed in Maine, New Hampshire, and Massachusetts, and we focus on light-commercial work — offices, retail, restaurants, clinics, salons, gyms, property management, and small mixed-use buildings. If you’d rather read about the dual-trade advantage in depth, see why one contractor for both trades matters.

Why Maine businesses hire one contractor for both trades

Commercial work crosses the line between electrical and HVAC constantly. A rooftop cooling unit needs dedicated circuits and a properly sized disconnect. A standby generator needs a transfer switch wired into your panel. An EV charging station for your lot comes down to your building’s electrical capacity. When one contractor owns both halves, the job gets designed and installed as a single coordinated project — instead of you managing two companies’ calendars and hoping their pieces line up.

• Less downtime — one crew sequences the whole job and works around your hours.
• One point of accountability — if anything’s off, it’s on us, not a blame game between trades.
• One quote, one schedule — covering the equipment and the electrical it depends on.
• Code-compliant, permitted work — handled together by the team doing the job.

Commercial electrical services

From keeping the lights on today to wiring a full tenant build-out, we handle the electrical side of your business end to end:

• Commercial electrical repairs — fast diagnosis and fixes that keep you operating.
• Commercial electrical installation, wiring, and service/panel upgrades — including tenant fit-outs and added capacity.
• Standby generators and backup power — so an outage doesn’t close your doors.
• Commercial EV charging stations — for workplaces, fleets, retail, and multi-family properties.
• Commercial LED lighting and retrofits — brighter spaces and lower energy bills.

Commercial HVAC services

Comfort keeps customers in the door and staff productive. We design, install, service, and maintain light-commercial heating and cooling:

• Commercial AC installation and commercial AC repair — rooftop units, ductless, and multi-zone systems.
• Commercial heating — installation and replacement sized to how your building is actually used.
• Rooftop units (RTUs), ventilation, and ductwork — service, replacement, and indoor-air-quality work.
• Preventive maintenance contracts — scheduled service that prevents the breakdowns that close businesses on the worst possible day.

The businesses we serve

Our light-commercial work fits the kinds of buildings that make up Maine’s Main Streets: offices and professional suites, retail storefronts, restaurants and cafes, medical and dental clinics, salons and gyms, churches and nonprofits, and the property managers and landlords who keep multi-tenant and mixed-use buildings running. We don’t take on heavy-industrial process work — we do the everyday electrical and comfort systems that keep local businesses open.

Built around your business, not the other way around

Closing for days isn’t an option for most owners, so we plan commercial work to keep you operating — staging the job in phases, scheduling the disruptive steps for after hours or weekends, and giving you a realistic timeline you can build your week around. You get one number to call and a team that treats your downtime as the real cost it is.

What working with one contractor looks like

Every commercial job starts with a free on-site assessment, not a guess over the phone. We look at how your building is actually used, what your electrical service can carry, and what your heating and cooling have to do through a Maine winter and summer — then we give you an honest plan and a firm recommendation, even when the honest answer is to repair what you have rather than replace it. From there, we schedule the work around your hours, keep the disruptive steps out of your busiest stretch, and hand you one timeline you can build your week around. When the job is done, the same team is who you call for service — not a vendor who has never seen your setup.

Comfort and power problems cost more than the repair

For a business, a dead cooling system on the hottest Saturday or a power failure during the lunch rush isn’t just a repair bill — it’s lost sales, sent-home staff, and customers who go somewhere else. That’s why we focus on systems that are sized right, installed to code, and maintained before they fail, and on electrical work that won’t become tomorrow’s emergency. Efficient, properly designed equipment also keeps showing up on your utility bill month after month, so the right install keeps paying you back long after the work is done. The goal is simple: keep your doors open, your space comfortable, and your power reliable — with one team accountable for all of it.

Questions Maine business owners ask us

Do you handle both commercial electrical and HVAC?

Yes — that’s our core advantage. We’re licensed for both trades, so a single team can handle your wiring, panels, generators, and EV chargers and your heating and cooling. For a business, that means one schedule, one quote that accounts for both sides, and one company accountable for keeping you open.

What kinds of businesses do you work with?

Light-commercial buildings — offices, retail, restaurants, clinics, salons, gyms, churches, and small mixed-use or multi-tenant properties, including work for property managers and landlords. We focus on those everyday commercial systems rather than heavy-industrial process work.

Can you work around our business hours to avoid downtime?

Yes. We phase commercial jobs and schedule the disruptive steps for after hours or weekends whenever possible, and we give you a plan to stay operational before we start. Minimizing your downtime is part of how we quote and sequence the work.

Are you licensed and insured for commercial work?

Yes — we’re a licensed electrical and HVAC contractor in Maine, New Hampshire, and Massachusetts, and we carry insurance for commercial jobs. Because we hold both trades in-house, your permitting and inspections are handled together rather than split between two companies.

What areas do you serve?

We serve commercial clients throughout Central Maine, the Kennebec Valley, and the Midcoast, including Augusta and the surrounding communities. If you’re not sure whether you’re in range, get in touch for a free estimate.
