I couldn’t recommend this business more!
Our heater went out at 9pm on a Tuesday night, we called multiple other businesses but the only ones able to come out were Sam and his team with third coast. They came right away and assessed the unit and left us with space heaters to make sure my kids and I were okay over night until they could come back the next morning to replace our furnace.
If I could give 100 stars I would.
They are beyond professional, accommodating and sincere people you can trust. Jim is a sheet metal whiz, and his level of detail and quality are beyond measure. Sam the owner, even stopped by to see how things were going and if I had any questions. Sam will always answer your call too - even on the weekends (thank you!).
