Heating, Cooling, Plumbing & Indoor Air Quality Services in Buxton, NC


HVAC and plumbing service for Buxton, with experience on local conditions built into every installation.


Buxton sits on one of the narrowest stretches of Hatteras Island, near the Cape Hatteras Lighthouse, where the ocean and the Pamlico Sound are both close enough to matter. Wind, salt, and the ocean overwash that comes with a nor’easter reach equipment sooner here than in the northern beach towns. That includes outdoor HVAC units, ground-level water heaters, and the supply lines under an elevated home.


R.A. Hoy has served Hatteras Island from our Kitty Hawk shop since 1979, and Buxton is a regular stop on the route. Our technicians install, repair, and maintain heating, cooling, and indoor air quality equipment in the village. Our licensed plumbers handle water heaters, drains, frozen and burst pipes, and the fixture repairs that keep a village home running.

Reliable Comfort: Experts in HVAC & IAQ

Timely response to customer inquiries and service requests. 24/7 availability for emergency support, ensuring customers are never left without assistance.

We have worked Hatteras Island from Kitty Hawk since 1979, and we group Buxton calls with our island route so a village appointment is not waiting on a special trip. Same-day appointments are arranged by phone, and the booking form on our website is open at any hour. Our website chat is staffed around the clock, which helps an owner who is checking on the house after a storm from somewhere else. Priority scheduling goes to homes on our maintenance plan.

Storm exposure is part of every recommendation we make here. Our technicians and licensed plumbers explain what they found, tell you what the storm did and what age did, and give you the price before the work starts. An insurance claim or a replacement decision is then based on a clear diagnosis.

My outdoor unit was standing in water during the last storm. Can it be saved?

The height the water reached decides it, so we open the unit before it runs again. Saltwater that reached the compressor terminals, the contactor, or the control board usually ends the unit. Water that only reached the base pan can be cleaned and dried, with the electrical components checked one by one. Do not restart a unit that was submerged until it has been inspected.

Do you install outdoor units on elevated stands in Buxton?

Yes. An elevated, anchored stand keeps the unit above the water that overwash and sound-side flooding push across the island, and the anchoring keeps it in place in high wind. We set the height based on the lot.

Can you thaw a frozen pipe, or do I have to wait for it to warm up?

Call us rather than waiting, because a frozen line that thaws on its own is the one that floods the house when the ice plug lets go. We thaw the line in a controlled way, check it for splits, and repair any section that has already cracked. Opening the faucet at the far end before we arrive relieves pressure on the line.

Should I replace the ductwork under my house after it was flooded?

Yes, if the duct itself got wet. Flexible duct and its insulation hold water and cannot be dried out, so a flooded run becomes a source of mold and odor even after the crawl space dries. We replace the flooded sections, seal the new connections, and check the air handler for water damage at the same time.

Will a tankless water heater keep up during a full week of summer guests?

Yes, within its rated flow. A tankless heater supplies hot water for as long as the taps run, but it heats a fixed amount of water per minute. A house with several showers running at once may need a larger unit or two in parallel. We size it for the number of fixtures likely to run together.

What other areas near Buxton do you serve?

Frisco and Hatteras Village are just down NC 12, and we serve the rest of the Cape Hatteras villages as well. Ocracoke by ferry and the northern Outer Banks up to Corolla are inside our coverage too.

Contact R.A. Hoy by phone, online booking, or website chat for HVAC, plumbing, or indoor air quality service in Buxton. Same-day appointments are available by phone, and island calls are grouped so the trip down NC 12 is already on the schedule. Our technician or plumber arrives with common parts, finds the problem, and gives you the price before the work begins.
