Aaron Evans founded Aurora HVAC Services on a single, non-negotiable principle: diagnose with data, not with guesswork. After years in the field witnessing technicians replace parts on a hunch, he built a company that operates on empirical measurement. Every technician on his team is NATE-certified and equipped with true-RMS multimeters, digital Bluetooth manifold gauges, and combustion analyzers. This isn't a sales operation; it's a mechanical engineering firm.
Aurora HVAC Services exists because Aaron believes homeowners deserve to understand what is happening inside their mechanical systems. We explain the physics. We show you the data. And we let the numbers dictate the repair—not a commission check.

"If you can't measure it, you can't manage it. We measure everything."
— Aaron Evans
The HVAC industry has a credibility problem. Too many companies dispatch undertrained technicians who diagnose by symptom rather than by science. A homeowner reports "my AC isn't blowing cold air," and the technician immediately assumes a refrigerant leak—charging hundreds of dollars to add Freon to a system that may have a completely different root cause. This is not engineering; it is guesswork, and it costs homeowners thousands of dollars in misdiagnoses over the life of their equipment.
At Aurora HVAC Services, we reject this model entirely. Our diagnostic protocol begins at the electrical panel and works systematically through the entire thermodynamic circuit. We measure voltage under load, amperage draw on the compressor, microfarad ratings on capacitors, and static pressure across the ductwork—before we ever touch the refrigerant system. When we do evaluate the refrigerant charge, we use digital Bluetooth manifold gauges to calculate precise Subcooling and Superheat values, which are the only scientifically valid methods for assessing system performance.
This engineering-first approach extends to our installations. We never guess on tonnage. Every replacement system begins with an ACCA Manual J Load Calculation—a mathematical model that accounts for your home's square footage, insulation R-values, window orientation, and occupancy to determine the exact BTU capacity required. An oversized system short-cycles, failing to remove humidity and dramatically shortening the compressor's lifespan. An undersized system runs perpetually, spiking your electric bill. Only the mathematical answer is acceptable.
Our installation commissioning protocol is equally rigorous. We flow inert nitrogen gas through the copper linesets during all brazing operations to prevent internal copper oxide scale (commonly known as "black death") from forming, which would eventually restrict the metering device and starve the evaporator coil. After brazing, we pull a deep vacuum to sub-500 microns to boil off any microscopic moisture trapped in the system—moisture that would mix with refrigerant to form hydrofluoric acid, which corrodes the compressor from the inside out.
This is the Aurora HVAC standard. Every repair. Every installation. Every time.
