Littlejohn HVAC Solutions is an owner-operated HVAC contractor in Greensboro, NC, working out of Burlington about 30 to 35 minutes east on I-40/85. Jesse Littlejohn handles AC repair, gas furnace and heat pump service, duct retrofits in older homes and light commercial rooftop work himself, with same-day service on most calls and emergency help around the clock.
Your local HVAC contractor for Greensboro, NC
Greensboro has no shortage of HVAC companies, so here's why people call a one-truck outfit from Burlington anyway: the person who answers is usually the person who shows up. Jesse Littlejohn runs the diagnosis himself, calls ahead when he's on the way, and puts written options in front of you before any work starts.
Most of the city sits 30 to 35 minutes west of us on I-40/85, and the east side along Wendover and US-70 is closer than that. Same-day service is realistic on most calls, including evenings when the upstairs of an old house won't drop below 80.
Historic Neighborhoods, Tight Chases, and Plaster Walls
The houses around Fisher Park, Irving Park, College Hill, and Westerwood were built long before central air. Heat came from radiators or a coal furnace, so today's ducts were squeezed in later: through closets, down old chimney chases, or across attics with barely a foot of clearance under the rafters. Undersized returns and long, crushed flex runs are the usual reason one bedroom is 8 degrees warmer than the rest.
Replacing ducts in these homes takes patience. We route new trunks where plaster and trim won't be torn up, seal every joint with mastic, and size the returns so the blower isn't straining. When a second floor simply can't be reached, a ductless mini-split for upstairs rooms often beats cutting into original walls.
Farther out, the mid-century ranches in Starmount Forest and the 1990s and 2000s subdivisions toward Lake Jeanette and Grandover bring different problems: aging gas furnaces with cracked igniters, and heat pumps approaching the end of their compressor life.
What a Typical Greensboro Call Looks Like
A common winter call in the older neighborhoods around UNCG is a gas furnace that lights, runs a minute, then shuts down. That pattern usually points to a dirty flame sensor or a weak hot-surface igniter, not a dead furnace. Cleaning or replacing the part and checking the draft often gets the heat back the same visit, and our gas furnace repair service is built around finding that root cause first.
In summer, the calls shift to the newer northwest subdivisions: a condenser humming but not spinning after a July storm. A failed run capacitor is the usual culprit, and it's a small repair, not a new system.
Downtown and around Elm Street, older commercial buildings add another layer: rooftop units serving shops and restaurants, many installed decades ago and patched ever since. We handle light commercial service there too, scheduling around business hours when we can. Back in the residential neighborhoods, spring pollen is its own problem. The yellow coating that settles over Greensboro every April clogs filters and outdoor coils within weeks, and a condenser choked with pollen and cottonwood fluff runs hotter, longer, and louder. A quick coil rinse and a fresh filter before June heads off a lot of the capacitor and compressor failures we'd otherwise see in July.
HVAC by home type in Greensboro
Greensboro's housing spans about a century, and each era hides its own weak spots.

Gas furnace with retrofit ducts
Retrofit ducts often feed one hallway return, so closed bedroom doors starve the blower and upstairs rooms run hot. We add jumper ducts or transfer grilles, reseal boots at the plaster and check the furnace's temperature rise. Where no trunk fits, a ductless mini-split system covers the top floor.

Gas furnace and split AC
Furnace, coil and ducts usually share a crawlspace or partial basement. Rusted coil pans, sagging trunks and oversized furnaces that short-cycle are common. We confirm the heat exchanger and venting are sound, then weigh a new coil and condenser against a properly matched heat pump system.

Zoned heat pump or one system per floor
Stuck zone dampers, failed zone boards and bonus rooms hung off the far end of a long attic run drive most comfort complaints in these homes. Our heat pump service covers the outdoor unit, and we test every damper and zone call before blaming the equipment.
Common HVAC problems in Greensboro homes
These are the faults we trace most often across Greensboro.
| Problem | Why it happens in Greensboro | What we do |
|---|---|---|
| A modern furnace venting into an old masonry chimney | Older Greensboro chimneys were built for coal; modern flue gas condenses inside and crumbles the mortar. | Jesse checks draft with burners firing and recommends a liner or sidewall vent if needed. |
| The bonus room stays hot while downstairs is fine | Rooms over garages in newer subdivisions sit at the end of the longest attic run. | We measure register airflow, reseal the run and add a missing return. |
| Zone dampers stuck open or shut on two-story homes | Zoned systems from around 2000 now have damper motors and boards near end of life. | We call each zone from the board and replace any damper that won't move. |
| Condensate water backing up and tripping the float switch | Humid Greensboro summers push heavy water through coils, and old drain lines clog with algae. | We clear the trap and line, test the float switch and add a cleanout tee. |

Why Greensboro residents choose Littlejohn HVAC Solutions
Greensboro homeowners can pick from plenty of large service companies with call centers and rotating crews. Here's what changes when the person on the phone is the licensed tech who shows up.
East-side calls land early on the route
Neighborhoods off Wendover Avenue and US-70 are the closest part of Greensboro to our Burlington base, so a dead condenser there is often a same-afternoon visit. The far northwest near Lake Jeanette takes longer, and we say so honestly when you call.
Retrofit ducts built by the person who designed them
In Fisher Park, Irving Park and College Hill, duct paths get planned around plaster, trim and old chimney chases. Jesse lays out the route, sizes the returns and does the complete duct installation himself, so nothing gets lost between a salesman and an install crew.
A second opinion before the big purchase
Greensboro homeowners often call after another company quoted a full replacement. Several of our reviews come from people told their system was finished who needed one part instead. We show you the failed component and hand you a free written estimate.
Rooftop units and storefronts near Elm Street
For downtown shops and restaurants, we service aging rooftop units and split systems and plan replacements around business hours. We're open 24/7 for HVAC emergencies, which matters when a dining room is full on an August evening.
A year of HVAC in Greensboro
Spring
Switch to cooling in April and let it run a full cycle before you need it. In Greensboro that first test often reveals a weak capacitor or clogged drain while there's still time to spare.
Summer
Long stretches in the 90s bring evening storms and power blips. After an outage, wait a few minutes before restarting. If the outdoor fan won't spin or the breaker trips twice, stop resetting it and call.
Fall
October is the right month for a combustion and safety check on Greensboro gas furnaces. We clean the flame sensor, test the igniter and limit switches, and inspect the venting before the first frosty night.
Winter
Heat pumps ice over and defrost several times on cold Greensboro mornings, which is completely normal. A unit stuck in solid ice for hours, or a furnace that keeps locking out, needs a real service call.
