Custom Ductless Mini-Split Systems for Historic & Custom Homes
Durham features unique architectural diversity—from historic 1920s bungalows in Trinity Park and Old West Durham to custom modern builds near Southpoint. Many historic homes rely on boiler radiator heat or lack duct space entirely.
Our ductless mini-split installation solutions provide targeted, whisper-quiet zone control without tearing into plaster walls or sacrificing original architectural details.
Emergency Furnace Repair & Heating Service
While Durham summers dominate cooling conversations, winter nights frequently dip below freezing. Whether your gas furnace experiences ignition failure, a cracked heat exchanger, or your heat pump enters auxiliary heat lockout mode, our technicians provide 24/7 emergency heating repair.
We perform strict safety checks, including carbon monoxide testing and gas valve pressure calibration, on every service call.
Seasonal Preventative HVAC Maintenance Plans
Preventative maintenance is the single most effective way to eliminate emergency breakdowns and extend system lifespans beyond 15 years. Our bi-annual tune-ups inspect and optimize key efficiency metrics:
-
Spring Cooling Tune-Up: Chemical coil cleaning, condensate line flush with algaecide treatment, subcooling/superheat refrigerant check, electrical capacitor testing, and fan motor amp draws.
-
Fall Heating Tune-Up: Gas burner cleaning, heat exchanger safety inspection, reversing valve operation check, safety limit switch testing, and thermostat calibration.
Why We Are Ranked Among the Best HVAC Companies in Durham
The Dual-License Advantage: Over 70% of HVAC component failures (shorted compressors, blown motors, non-responsive thermostats) stem from underlying electrical issues. Standard HVAC companies are legally restricted from working on your main panel breaker or primary electrical wiring.
Because Dawson's holds master credentials in both licensed electrical and mechanical NATE certified HVAC fields, our team resolves both sides of the issue in a single seamless visit—saving you time, hassle, and double diagnostic fees.

Job Locations and Reviews
Performed a complete heating and air maintenance with an 80-point inspection on each system, including outdoor coil cleaning, burner cleaning, gas pressure adjustment as needed, and safety inspections. Inspected the air handler cabinet and found the evaporator coil clean with no frost or ice buildup and the control board wiring free of visible damage, though some low-voltage conductors were loosely routed.
Performed a quality control inspection of the newly installed system, including evaluating the concrete pad beneath the outdoor condenser, which was reported to sit on a slope, and assessing the potential for erosion and settling during rainfall. Verified furnace operation with a dual-port manometer, confirming stable pressure readings and normal burner flame, and inspected the condenser electrical compartment, confirming secure low-voltage wiring connections, liquid-tight conduit routing, and properly capped refrigerant service valves.
Responded to a no-heat call on two 2021 Daikin ductless mini-split systems with a blinking red indicator light and diagnosed a refrigerant line set fault. Inspection of the insulated line set revealed torn insulation and significant corrosion on the flare fittings and copper tubing, indicating a probable refrigerant leak. Verified operation from the remote controller and documented the line set deterioration, with repair of the affected fittings and line set recommended to restore heating.
Performed preventive maintenance on one 8-15 year old heating and cooling system, including an 80-point inspection, outdoor coil cleaning, burner cleaning, and gas pressure adjustment to manufacturer specifications. Completed safety inspections and checked the condensate pump, refrigerant line insulation, and flue venting for proper installation and condition, with no frost, rust, or significant damage observed.
Performed a complete heating and cooling maintenance on a one-year-old system, including an 80-point inspection of the air handler and outdoor condenser. Cleaned the outdoor coil and burners, adjusted gas pressures to specification, and completed safety inspections. Verified the condensate drain line and sealed, insulated supply duct connections were in good condition, with no signs of rust, frost, or damage observed.
Responded to a no-cool complaint on a 22-year-old system that has been unable to maintain setpoint for two years. Inspected the evaporator coil and found fins coated with heavy dust and lint buildup restricting airflow and heat transfer. Also found the supply plenum's foil-faced duct insulation torn, creased, and discolored at the cabinet connection, indicating air leakage and insulation loss that reduce system capacity.
Replaced the failed furnace control board and transferred the wiring harness connections to the new board, verifying all connectors were fully seated and conductors secured with zip ties. Inspected the wiring and connectors for damage, corrosion, or burn marks and found none. Confirmed the DIP switch settings matched the application, then verified proper furnace operation after installation. Replacement was completed under the existing warranty coverage, which remains active through 2028.
Diagnosed a gas furnace with delayed heat-call response and abnormal startup noise by inspecting the cabinet and testing the inducer, gas valve, and control board wiring with a multimeter and clamp meter. Verified voltage and amperage readings through the ignition sequence to isolate the cause of the extended start-up delay.
Installed a gas-fired upright furnace in the attic on a raised base, with the insulated refrigerant line set connected and supported by straps, condensate drain piped in PVC, flexible gas connection with shutoff valve, and low-voltage control wiring secured. Vented the unit to the existing flue and installed a Honeywell smart thermostat with a new carbon monoxide alarm on the living space wall. Started the system and verified heating operation, with the thermostat calling for heat and the fan running in auto mode.
Performed a complete heating and cooling preventive maintenance on a Trane packaged unit, including an 80-point inspection, outdoor coil cleaning, burner cleaning, gas pressure adjustment as needed, and safety inspections. Documented the unit's exterior as weathered but intact with no visible frost or rust, and noted dirt buildup and flaking residue around a flexible duct collar connection.
