About · est. 2011
Built by an engineer who got tired of the guessing.
Ray Delgado spent a decade keeping casino resorts cold — where 'probably fine' is not an acceptable reading. Meridian Air is that discipline, sized for your house.
The moment this company exists because of: 2010, a kitchen table in Spring Valley, Ray's mother holding a quote for a 5-ton air conditioner. Her house, by the math Ray ran that evening on the back of the quote itself, needed three and a half. The salesman hadn't measured anything. He hadn't even gone into the attic.
Ray had spent the previous decade as a chief building engineer on the Strip, responsible for the chilled-water plants and air handling of properties where a cooling failure makes the evening news. In that world, nothing gets replaced without load data, nothing gets commissioned without verification, and nobody's pay depends on selling a bigger chiller. He quit in 2011 and started Meridian Air to run residential HVAC the same way.
Fifteen years later the company is 9 technicians, a dedicated duct crew, and a shop full of instruments off Patrick Lane — and the operating rule hasn't moved an inch: no claim without a measurement behind it. It's why our techs are salaried instead of commissioned, why every install starts with a Manual J, and why your invoice has before-and-after readings printed on it.
The name, if you're wondering: a meridian is a reference line — the fixed thing you measure everything else against. That felt about right.

SPEC A
Company log
1998–2010
Ray Delgado runs building engineering for two Strip resorts — thousands of tons of cooling, where a bad reading means a very bad night. Everything is measured, logged, verified.
2011
Ray watches his own mother get quoted a 5-ton unit for a house that needed 3.5. Meridian Air opens that year with one truck, one rule: no claim without a measurement behind it.
2016
The ±2° room-to-room balance guarantee goes on every contract — because by now the data shows we hit it anyway. The Care Plan launches the same year.
2020
Fifth truck, first dedicated duct crew. Duct sealing becomes a third of our work as the valley's 90s housing stock hits the failure curve together.
Today
9 NATE-certified technicians, all salaried employees, all background-checked, all in marked trucks. Still one rule. Still measuring.
SPEC B
Operating rules
Salary, not commission
Nobody in your home earns a percentage of what they sell you. It's the single most important structural decision in this company, and it's why our diagnostic reports read like data sheets.
Math before metal
A Manual J load calculation on every replacement quote, free, no exceptions — since day one. We will not sell you a system sized by a rule of thumb.
Both numbers, always
Static pressure before and after. Leakage before and after. If work doesn't produce a measurable difference, why did you pay for it? You get the before and the after, in writing.
The boring guarantee
±2° room-to-room, on the contract. It's not marketing flair — it's an engineering spec we design to, and the callback rate proves it.
