Walk down Churton Street past the old courthouse and you're looking at buildings that were standing before anyone imagined air conditioning. Keeping people comfortable inside them without scarring plaster or visible trim is a specialty, and it's a big part of the HVAC work we do in Hillsborough.
We drive in from Burlington in about 25 to 30 minutes on I-40/85. That makes same-day service realistic on most calls, whether the house was built in 1790 or 2015.
Why Historic Hillsborough Homes Suit Ductless
Hillsborough's historic district holds homes from the 18th and 19th centuries: Federal and Greek Revival houses, timber-framed cottages, and later Victorians. Walls are often solid plaster on lath, ceilings are tall, attics are cramped or missing, and many sit on low stone foundations with little crawlspace. Running full-size ductwork through them usually means cutting into historic fabric.
A ductless mini-split needs only a small hole for the refrigerant line set and can put a slim head, floor console, or concealed ceiling cassette in each room. The outdoor unit can sit behind the house, out of view from the street. Zoned heads also suit these homes' layouts, since closed-off parlors and upstairs bedrooms rarely share one thermostat's needs.
Old houses also leak air. We talk through simple sealing at the attic hatch and around sash windows, because no system should fight a drafty envelope alone.
Beyond the Historic District
Not every Hillsborough home is antique. Neighborhoods like Waterstone and Churton Grove were built in the last few decades, and they run conventional heat pumps with ducts in the attic. Those calls look more like the rest of the Triangle: capacitor failures in July, clogged condensate lines, and systems reaching replacement age.
Near the Eno River and the Riverwalk, the damp bottomland keeps crawlspaces humid, and we often find sweating ducts and rusted air handler pans. A common call in older in-town homes is a window-unit household ready to switch to something quieter. For those, we start by measuring rooms and heat loss, then map out where heads and line sets can go. When your existing central system needs attention instead, our heat pump repair covers it.
Winter brings its own historic-home calls. Many older Hillsborough houses still rely on an aging oil or gas boiler, a floor furnace, or a patchwork of space heaters, and owners look for a cleaner, safer option. Ductless heat pumps can handle most Piedmont winter nights on their own, and they pair well with an existing boiler kept as backup for the coldest stretches. We'll talk through whether keeping the old system makes sense or whether it can be retired entirely, and we explain the tradeoffs in plain language before you commit to anything.
HVAC by home type in Hillsborough
Hillsborough work falls into three kinds of houses, each with its own trade-offs.
Federal and Greek Revival homes downtown
Multi-zone ductless heat pump
The hidden challenge is condensate. Each indoor head produces water that needs a path out without staining plaster or dripping down a facade. We route drains inside closets or through the foundation and use quiet pumps where gravity won't work. Steady dehumidification also protects old woodwork from seasonal swelling.
Mid-century in-town cottages still on window units
Single-zone ductless heads
Owners often want to replace three or four window units at once. The choice is several single-zone systems or one multi-zone outdoor unit, and the panel may need a new circuit either way. We check electrical capacity first, then size each head to its room so none short-cycles.
Newer homes in Waterstone and Churton Grove
Ducted heat pump, often two systems
Most of these systems are now old enough for their first major repairs. Upstairs units in hot attics work hardest and usually fail first. We test capacitors and check refrigerant charge, and when replacement makes sense, our HVAC installation service starts with a room-by-room load calculation.
Common HVAC problems in Hillsborough homes
Frequent Hillsborough service calls.
| Problem | Why it happens in Hillsborough | What we do |
|---|---|---|
| Water dripping from a wall-mounted ductless head indoors | Condensate lines in older Hillsborough homes run long, flat routes that clog or lose slope. | We flush the line, restore proper pitch and install a condensate pump if needed. |
| Upstairs bedrooms in a historic house overheat by afternoon | Tall, uninsulated roof framing above top-floor rooms gains heat all day in summer. | We confirm the head's capacity, check its filters and suggest attic air sealing. |
| Musty odor from a mini-split after a few years | Humid air near the Eno lets mold build on blower wheels inside the indoor heads. | We pull the cover, deep-clean the blower wheel and coil and flush the drain pan. |
| Breaker trips when a new unit starts up | Older in-town panels were never sized for heat pump starting current. | Jesse measures startup amps and recommends a dedicated circuit or soft-start kit. |

Why Hillsborough residents choose Littlejohn HVAC Solutions
Hillsborough splits between the historic streets around Churton Street and neighborhoods built in the last few decades. We're comfortable in both, and here's how that shows up on a service call.
Room-by-room loads, not guesses
Parlors, closed-off bedrooms and tall ceilings each carry a different load. We measure room by room before recommending heads, so an older Hillsborough house gets the smallest ductless setup that keeps every space comfortable.
Condensers kept out of sight
Outdoor units go at the rear or side of the house, with line sets run along discreet paths. That keeps the street view intact and keeps the historic-district review simpler for you.
Retiring window units and space heaters
Many in-town households still run window units in summer and space heaters in winter. Ductless heat pumps replace both with quieter, safer equipment, and they can work alongside an old boiler kept as backup.
Routine repairs in newer subdivisions
In Waterstone and Churton Grove, the calls are July capacitor failures and clogged condensate lines. Jesse carries common parts, calls ahead, and charges for the fix you need rather than the one that pays best.
A year of HVAC in Hillsborough
Spring
Rinse or vacuum the washable filters in every ductless head once pollen season hits. In Hillsborough's older homes, that usually means several heads, and neglected ones lose airflow quickly. Also check that outdoor units still sit level.
Summer
Humid days favor dry mode on ductless heads. Set the upstairs rooms first, since heat stacks there. If a head blows warm air while its outdoor unit sits silent, call before the rest of the house suffers.
Fall
Switch heads to heat on a cool October morning and listen for rattles or clicking from the outdoor units. For Hillsborough homes keeping an old boiler as backup, have it checked now so it's ready for the rare hard freeze.
Winter
Keep snow and ice clear of outdoor units, especially those tucked behind houses where roof runoff falls. During defrost, a ductless head may pause blowing for a few minutes. That's normal; a head that stays cold for an hour isn't.
