If you can dream it we can build it. We can build from your plans, or we can do both the design and construction. We offer both residential and commercial construction services as a licensed general contractor. For residential customers we offer an array of services for almost any project. We offer competitive pricing and exceptional quality and customer service.

"I can't say enough about the excellent work that Carolina Contracting did completely demoing an existing wood deck and constructing a new TimberTech deck. The project was challenging. The deck is sixteen feet off the ground with +20 stairs and extensive lighting. It was done on budget and on time. Scott Dean and his team worked hard every day on the project from early morning to dusk. They are true craftsmen. Communication was exemplary throughout the 3-4 week project."

Boiler Repair questions, answered by experts

When it comes to bleeding a radiator, the goal is to let out trapped air rather than letting out the water. Naturally, some water will dribble out when you open the valve to let out the air. But you don’t want a lot of water to leak out. Just leave the valve open long enough that the hissing noise stops, meaning the air has escaped, and just a dribble of water comes out of the radiator.

Over time, a radiator can leak if turned off due to the built-up air pressure, which can cause water or coolant to leak. If your radiator leaks when it’s off, turn your whole system off and bleed the radiator, then turn it back on. If it’s still leaking, you might want to have an HVAC professional look at the issue.

If you’re unsure who to call to fix your boiler, you have a few options. One is to call a dedicated boiler service. However, you can also call a plumber or HVAC technician for boiler repair services. These pros will have the tools, knowledge, and experience to fix common boiler problems.

Scale from hard water is hard to diagnose until it starts causing problems. If your area has particularly hard water, that’s most likely what your boiler is using. If scale build-up becomes a problem, it starts to cause decreased flow and heating, and eventually, valve failures as valves become blocked. Let boiler professionals know if you’re worried about scale and they can offer advice or implement a solution.

HVAC maintenance is crucial for the longevity of your unit. Without proper care, your HVAC unit can break down frequently. In addition, a system that is dirty and not cleaned correctly will not heat or cool as efficiently and will increase your energy bills due to the increase in energy consumption. Additionally, you will probably have to replace your unit sooner than you would if it were properly maintained, which will cost you more money.
