The things we treat as non-negotiable on every Merrimac job.
Flat pricing quoted before the work starts. Same-day and next-day slots available across Massachusetts.
“Bought an EV and had no idea what my panel could handle. They did the load calculation, told me straight that I had room, and installed the charger two days later.”
“Lost a furnace board and a TV in one storm. They put a surge device on the panel and explained exactly what it does and doesn't cover.”
“Called at 11pm when half the house went dark and an outlet was making a noise I'd never heard before. Someone was at the door in under an hour and had it isolated before midnight.”
Most Merrimac service calls are scheduled same-day or next-day, and emergency calls are dispatched around the clock. Call (833) 652-8933 and we'll give you a real arrival window before we hang up.
