Co-Founder at Product Air Heating, Cooling and Electric. Serving Marysville, Issaquah, Seattle, and Western Washington
Eli Nikolin was born in Stanwood, Washington, the tenth of eighteen children in a family that immigrated from Russia in 1991. The Nikolins ran a small farm, goats and all, and every kid was assigned something to keep alive or keep running. Eli says that’s where the work ethic came from, and where he learned that responsibility means answering for the outcome, not just showing up.
Eli has worked in HVAC for 12 years, starting as a teenager mechanically inclined toward engines and dirt bikes. Four years in, he was working a day job in the trade and running his own service and install calls in the evenings, some nights not getting home until one in the morning. That pace lasted until 2017, when his brothers Robert and Sergey Nikolin pushed him to go all in, and Eli founded Product Air Heating, Cooling and Electric. By a conservative estimate built from his own daily call volume, four to five homes a day, five days a week, across 12 years, Eli has personally worked on more than 6,000 HVAC systems across Western Washington.
Before Product Air, Eli spent nearly four years in the Local 32 HVAC apprenticeship program in Seattle, a five-year track combining coursework with fieldwork. He left two-thirds of the way through to launch the company, a trade-off he made deliberately: finishing would have meant a commercial license, and Eli wanted to build a residential business serving homeowners directly.
Eli holds an EPA Section 608 refrigerant certification, a City of Seattle gas piping license, a 06A low-voltage electrical certification, and a 01 electrical administrator license, the credential that lets Product Air run its own in-house electrical department rather than subcontracting that work out. Product Air itself operates under Washington State business license #604346979 and is a registered construction contractor with the state Department of Labor & Industries, which any homeowner can confirm directly through L&I’s contractor verification tool.
The company’s full list of manufacturer and trade certifications, including its Mitsubishi installer credentials and Seattle refrigeration and gas piping licenses, is published on the Product Air certificates page.
Eli’s reputation in the field comes down to one habit: he doesn’t let homeowners take his word for it. He brings a camera into the crawl space or the furnace cabinet and shows them exactly what he’s looking at, live, before he recommends anything, a habit built from watching too many people get talked into work they didn’t need.
That approach paid off for a homeowner in Lake Stevens who’d already had three companies out trying to troubleshoot a system that ran but wouldn’t heat or cool, one of them spending two full days on-site without finding the fault. The homeowner was about to spend $14,000 to $15,000 on a full replacement. Eli started at the basics, checked power, checked communication between components, and found a seized compressor in five minutes.
A $4,000 compressor swap solved it. He’s also advised against repair when it wasn’t the right call: one homeowner had been getting lightheaded and headachy at home, and Eli’s camera inspection found cracked holes in the heat exchanger of her 30-year-old furnace, meaning combustion exhaust was leaking into the living space. Rather than patch a system already twice past its expected lifespan, he laid out both options and let her choose replacement. She never had another headache.
On the product side, Eli’s specialty is heat pumps and the communication protocols that let a Mitsubishi system’s indoor and outdoor components talk to each other correctly, the kind of schematic-level knowledge that separates a system that runs from a system that’s actually commissioned right. That focus is part of why Product Air was named a Mitsubishi Diamond Contractor, and in 2026 advanced to Elite Diamond Contractor, a tier Mitsubishi Electric reserves for roughly the top 5 percent of its dealer network based on factory training, installation volume, and customer satisfaction history.
A lot of Eli’s day-to-day work is problem-solving around housing stock that predates modern comfort expectations. Older Seattle homes were often built with low ceilings and tight staircases leading into the spaces where HVAC equipment has to live, forcing undersized or oversized systems into rooms that were never meant to hold one. Eli treats duct sizing as the make-or-break detail on every job: an oversized system fit to a small duct run will overwork its blower motor and burn out a compressor years early, while a system sized to the house instead of the ductwork can run 15 to 20 years instead of 8 to 10.
Washington’s climate shapes the same decisions from another angle. Homes here run heat for 9 to 10 months a year and cooling for barely 2, which is exactly the profile a heat pump is built for, since it rarely has to drop into auxiliary heat below 25 to 30 degrees. Eli has walked homeowners through three-story, 5,000 to 6,000 square foot houses running on a single undersized duct system, splitting floors into independent zones with new return ducting so upper-floor bedrooms finally get the airflow the original design never accounted for.
Eli runs Product Air alongside Robert, who oversees field operations and technician training, and Sergey, who handles the company’s customer-facing story on the Product Air blog. Internally, Eli’s approach to quality starts with owning mistakes out loud. Product Air holds monthly team meetings where errors get named and discussed rather than buried, a habit Eli credits with building the trust that lets technicians extend the same honesty to homeowners. When installation quality slips on a job, whether flagged by a customer review or a city inspection, the crew gets retrained at the shop before the next call goes out.
Twelve years and roughly 6,000 homes into the trade, Eli says the reputation he wants for Product Air a decade from now hasn’t changed since 2017: the most honest, highest-quality HVAC and electrical company in Western Washington. It’s the same idea behind the company’s own tagline, “Your Tech Brother from Another Mother,” and Eli means it plainly. Walk into a homeowner’s house the way you’d walk into your own brother’s, and you’ll never have to wonder if you did right by them.
