Brunswick, Topsham, Bath, Harpswell, and surrounding Midcoast Maine communities
From emergency repairs to full HVAC installs, Coastal Plumbing & Heating keeps Midcoast Maine homes running all year long.
ABC Heating has been serving Brunswick and the surrounding Midcoast Maine communities for over two decades. We started as a small operation with a single service van and a commitment to doing honest work at a fair price — and that hasn't changed. Whether you're dealing with a burst pipe in January or a furnace that gave out overnight, we show up ready to solve the problem, not upsell you on things you don't need. We handle everything from routine plumbing repairs and water heater replacements to full HVAC installations and boiler service. Our team knows Maine winters — we understand what coastal salt air does to fittings, what old farmhouse plumbing looks like, and why a reliable heating system isn't a luxury up here, it's a necessity. We work on all types of homes, from century-old colonials in downtown Brunswick to newer builds out in Topsham and Harpswell. As a locally owned and operated business, we take our reputation seriously. Our customers are our neighbors, and word travels fast in a small town. That's why we stand behind every job we complete, offer transparent pricing before any work begins, and make ourselves available when real emergencies come up. When you call Coastal, you get a real person — and a crew that genuinely cares about getting it right.
From leaky faucets to broken shut-off valves, we handle the full range of residential plumbing repairs. No job is too small, and we diagnose the root cause so the fix actually lasts. We serve Brunswick, Topsham, Bath, and the surrounding Midcoast area.
Cold showers in a Maine winter are more than an inconvenience — they're a sign something needs to be fixed now. We install and service traditional tank water heaters, tankless on-demand units, and heat pump water heaters. Fast turnaround, competitive pricing.
Your heating system is the most critical mechanical system in your home during a Maine winter. We install, service, and repair oil and gas boilers, forced hot air furnaces, and radiant heating systems. We keep you warm when it matters most.
"Our boiler stopped working on a Friday night in February. Coastal had someone here within two hours and had the heat back on before midnight. Fair price, no drama, and they even checked our thermostat settings before they left. These guys are the real deal."Karen T.Brunswick, ME
"I had three plumbers look at a chronic low-pressure issue in my old farmhouse. Coastal was the only one who actually found the cause — a partially closed valve buried in the crawlspace. Fixed in 20 minutes. I wish I'd called them first."Mike D.Topsham, ME
"We had Coastal install a ductless mini-split last spring and it has been a game changer for our home. The crew was professional, cleaned up completely, and walked us through the system before they left. Already recommending them to everyone on our street."Sandra H.Bath, ME
"Honest, reliable, and they actually answer the phone. I've used Coastal for three different jobs now — water heater replacement, a drain issue, and a leaky pipe under the sink. Every time, they show up when they say they will and charge what they quoted."Tom W.Harpswell, ME
