24/7 emergency HVAC · North Texas
When the air goes out in August, you do not want a callback window.
You want someone at the door. We run emergency trucks around the clock and quote before we touch anything.

Services
Emergency AC Repair
Round-the-clock trucks stocked for the failures that actually happen: capacitors, compressors, blowers.
System Replacement
Load-calculated sizing so you are not cooling a house twice your square footage.
Heating & Furnace
Ignition, heat exchanger and thermostat work, with a safety inspection on every call.
Maintenance Plans
Two tune-ups a year, priority dispatch and no overtime rates when something breaks at midnight.
Indoor Air Quality
Filtration, UV and humidity control for households with allergies or asthma.
Ductwork
Leak testing and sealing — most homes lose a quarter of their conditioned air before it reaches a vent.
Northline has run out of the same Plano shop since 2009. Every technician is NATE-certified and background-checked, and we do not pay commission on parts — so nobody here has a reason to sell you a system you do not need.
“Out at 11pm on a Saturday, fixed in an hour, charged exactly what they quoted.”
