Southern Maine trusts Cardinal.

Our furnace died at 11pm in January with a newborn in the house. Cardinal had a tech here within the hour and heat back on before 1am. I’ll never call anyone else.

They installed two heat pumps and walked me through every Efficiency Maine rebate. The final cost was thousands less than the franchise quote down the road.

What sold me was the upfront price. No mystery hourly charges, no "oh and you also need this." Honest people, clean work.

Their maintenance plan caught a cracked part before it failed. They literally saved me a no-heat weekend. Worth every penny.

Mini-splits in our finished attic completely fixed the room that was always too hot. Quiet, tidy install, and they hauled everything away.

Showed up inside the two-hour window, texted when they were on the way, and explained exactly what was wrong. That’s rare these days.
