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.
