Heating, Cooling, Plumbing & Indoor Air Quality Services in Colington, NC
Heating, cooling, and plumbing care for Colington’s canal-front homes, with the price set before work begins.
Colington Island sits just west of Kill Devil Hills, low to the water and full of canals. Homes on a canal sit close to the water, which keeps the air humid year-round. It also puts HVAC equipment, water heaters, and plumbing at ground level within reach of a sound-side flood.
R.A. Hoy has served Colington from Kitty Hawk since 1979. Our technicians install, repair, and maintain heating, cooling, and indoor air quality systems on the island. Our licensed plumbers handle water heaters, drains, pipe repairs, and the fixture work that comes with a waterfront home.

Heating, Cooling, Plumbing & Air Quality Services for Colington Homes
Heating and Cooling Services in Colington
We install, repair, and maintain heating and cooling equipment across Colington Island and Colington Harbour. Moisture is the constant here, so we size and set up each system to remove humidity as well as heat.
Heat Pump and Furnace Service in Colington
We repair and replace the heat pumps and furnaces that keep Colington homes warm. On a canal lot we pay attention to where the outdoor unit sits. A unit at grade next to the water takes on humidity, salt, and the occasional flood, and an elevated stand solves two of the three.
Air Conditioning Repair and Installation in Colington
An air conditioner on the canal runs long hours against moisture coming off the water, and a system that is too large shuts off before the air is dry. We repair units that have stopped cooling and size replacements for the humidity load of a waterfront house.
Ductless Mini-Splits for Boathouses and Additions in Colington
A boathouse loft, a converted garage, or an addition built out toward the canal rarely has ductwork. A ductless mini-split conditions the space on its own, and the indoor unit mounts high on the wall where flooding is not a concern.
Smart Thermostat Installation in Colington
A smart thermostat that reports humidity as well as temperature gives a Colington owner an early warning when the house is drifting toward a mildew problem. We install it, connect it to the equipment, and set the schedule with you.
Plumbing Services in Colington
Our licensed plumbers repair, replace, and install plumbing for Colington homes, and the work starts only after you have heard the diagnosis and the price. The trucks carry common parts, so a leaking shutoff or a toilet that will not stop running is often fixed on the first visit.
Water Heater Repair and Replacement in Colington
Water heaters at ground level on a canal lot sit in the dampest air on the island and are the first appliance to go under in a sound-side flood. We repair and replace water heaters, raise them onto a stand or a platform where the house allows it, and install tankless water heaters on the wall out of the way.
Drain Cleaning and Sewer Lines in Colington
Low-lying lots drain slowly, and a main drain line that sits near the water table can hold water and settle over time. We clear clogs with drain cleaning, run a camera inspection when a backup keeps returning, and repair sewer lines between the house and the septic tank or sewer connection.
Pipe Repair and Repiping in Colington
Salt-laden air corrodes exposed copper and brass fittings under a canal-front house, and a pinhole leak over the water goes unnoticed longer than one inside a wall. We repair pipes and general plumbing, fix faucets that drip or have lost pressure, and repipe homes whose lines have reached the end of their life.
Indoor Air Quality Services in Colington
We install and repair indoor air quality equipment for Colington homes, where the air inside carries the humidity of the water outside unless something removes it.
Air Duct Sealing and Repair in Colington
Ductwork in a crawl space that stays damp year-round pulls moisture into the system through open joints and sends it to every room. We seal and repair air ducts, insulate the runs that sweat, and replace sections that have soaked through.
Whole-Home Dehumidifiers in Colington
A whole-home dehumidifier tied into the HVAC system removes moisture around the clock, including the spring and fall weeks when the air conditioner barely runs. On a canal lot it keeps mildew from getting a start in the closets and the crawl space.

What Colington Homeowners Can Expect From R.A. Hoy
Colington is a short drive from our Kitty Hawk shop by way of Colington Road, and we have served the island since 1979. Same-day appointments are available by phone, and you can book online or by website chat at any hour. Homes on our maintenance plan get priority scheduling. On an island where humidity is constant, a spring and fall visit keeps a small problem from becoming a flooded crawl space.
Our technicians and licensed plumbers explain what they find and give you the price before any work begins. If the part is on the truck, the repair is finished the same visit; if it is not, you know exactly what is coming and what it costs before we leave.
FAQs About HVAC, Plumbing & Indoor Air Quality in Colington
What should I do about my HVAC and water heater if the canal floods the yard?
If you can do so safely, turn off power to the outdoor unit and the water heater at the breaker before water reaches them. Do not restart either until it has been inspected. Floodwater corrodes electrical components and contaminates a tank, and a unit that starts after a flood can fail in ways that cost more than the inspection. We check both before you turn them back on.
Can you raise my outdoor unit and water heater above the flood line?
Yes. We install outdoor HVAC units on elevated stands, and we set water heaters on platforms or switch them to a wall-mounted tankless unit. That keeps the equipment above the water a sound-side storm pushes in. We look at the house and the lot and tell you what height makes sense.
Is a dehumidifier still necessary if my air conditioner has a dry or dehumidify setting?
A dehumidify setting slows the fan so the coil pulls more moisture, which helps on a hot day when the system is running anyway. In spring and fall the air conditioner runs too little to dry the house no matter what setting it is on. A whole-home dehumidifier works independently of cooling, which is why it matters on a canal lot.
My water pressure drops when two fixtures run at once. Is that a pipe problem?
On county water the usual causes are a failing pressure regulator, a partly closed main shutoff, or supply lines that have corroded and narrowed inside. We run a water pressure assessment to find which one it is, and the fix ranges from a new regulator to a repipe.
How do I know whether the musty smell is coming from the ducts or the crawl space?
A smell that is strongest when the system first starts points to the ducts, where moisture and dust have settled in the lines. A smell that is there all the time, strongest near the floor, points to the crawl space. Sealed ducts stop the system from pulling crawl space air inside, and a dehumidifier dries the space itself. We inspect both and tell you which one you are dealing with.
What other areas near Colington do you serve?
Kill Devil Hills is next door, Kitty Hawk and our shop are just up the road, and Nags Head and Manteo are a short drive south. We serve the rest of the Outer Banks and mainland Currituck County as well.
