Donald Arnold + 4 NATE Techs | Velox Cache Valley Team

Meet the Velox Heating and Air Team

Cache Valley HVAC isn’t a generalist trade. The 4,525-foot elevation changes combustion math. The 12–14 grain Logan municipal water changes humidifier service intervals. The Bear River Range traps PM2.5 below 4,800 feet during PCAPS inversion stretches that can run 12 days. None of that is in the standard manufacturer training binder. Five people show up to Velox service calls. Each of them has logged the local hours to know what those numbers mean on a Tuesday at 3 a.m. when your furnace stops.

Donald Arnold — Owner & Lead Technician

Donald founded Velox in 2014 after seven years at a Carrier dealership on North Main Street near the Cache Valley Mall corridor. He holds Utah DOPL HVAC contractor license #10234567-5501 and EPA Section 608 Universal certification #608U-2011-385729. His NATE specialty certifications cover Air Conditioning Service, Air Distribution, and Gas Heating Service. ACCA Manual J, S, and D coursework completed 2012 through HVAC Excellence. RSES Class HE member since 2013.

Donald handles the technically difficult diagnostic calls personally — intermittent ignition lockouts that don’t reproduce on a service tech visit, suspected heat-exchanger cracks that need borescope verification, hydronic system air-binding in pre-1950 cast-iron radiators across Logan’s Center Street historic district. He still answers the after-hours phone on rotating weekends, which most owners stop doing by year five. He’s now in year twelve.

Marcus Reyes — Service Manager

Marcus has worked Cache Valley HVAC since 2013, joining Velox in 2017 and stepping into the service manager role in 2020. He holds NATE Heat Pump Service, NATE HVAC Efficiency Analyst, and EPA Section 608 Universal certifications. Marcus runs dispatch, parts inventory, and technician routing — the operational spine of a same-day-response company in a county that spans 50 miles north to south.

His technical depth is cold-climate heat pumps. Marcus led Velox’s 2023 internal planning for the R-454B refrigerant transition, attended factory training at Mitsubishi Electric’s Suwanee facility for Hyper-Heat low-ambient cold-climate units, and now writes the company’s heat-pump selection guides for properties above 4,800 feet (the Cliffside neighborhood, North Logan’s east bench, Hyde Park foothill acreage). When a homeowner in Providence asks why their neighbor’s 14-SEER single-stage heat pump won’t hold setpoint below 25°F, Marcus is the one who explains AHRI test ratings versus real-world performance at 3°F.

Annika Jorgensen — Senior Install Technician

Annika graduated from Bridgerland Technical College’s HVAC program in 2017 with the high-honors HVAC/R Excellence Award. She joined Velox in 2019 after two years on commercial-residential split crews in northern Utah. Her certifications: NATE Air Distribution, NATE Gas Heating Installer, EPA Section 608 Universal, and OSHA 10-hour Construction.

Annika runs Velox’s technically demanding installations — new-construction zoned systems in tight-envelope Nibley and Providence builds where mechanical ventilation is code-required, heat pump conversions in 1930s Logan brick homes where existing duct trunks were never sized for modern airflow, and HRV/ERV layouts in the post-2015 Smiling H Subdivision homes that test below 2.0 ACH50 at blower-door certification. Her load calculation discipline catches the issues that show up two winters later in worse hands: condensation in flex returns, short-cycling on oversized cooling, hot spots on second floors.

Calvin Howell — Comfort Advisor & Estimator

Calvin handles in-home consultations, load calculations, and equipment selection for replacement and new-system projects. Before joining Velox in 2018, he spent four years as a licensed home inspector working pre-purchase inspections across Cache and Box Elder counties, which means he’s seen the inside of more 1890s Center Street homes, 1940s Bridger-neighborhood ranches, and 2010-onward Nibley subdivisions than most contractors will encounter in a career.

His ACCA Manual J coursework completed in 2019. The discipline matters because the 1925 brick four-square in Logan’s Ellis neighborhood, with original sash windows and uninsulated balloon-frame wall cavities, often carries an 80,000–95,000 BTU/hr design heating load on 2,100 finished square feet. A 2021 Nibley new build with R-49 attic, R-21 walls, R-10 slab perimeter, and triple-pane fiberglass windows on the same square footage might carry 32,000–38,000 BTU/hr. Calvin is the reason customers don’t get sold an 80,000 BTU furnace for the Nibley house, or a 60,000 BTU furnace for the Ellis house. Both happen often in this market.

Bridget Castro — Dispatcher & Office Manager

Bridget joined Velox in 2020 and runs scheduling, maintenance-plan member coordination, and permit administration with Logan City Building Inspection, North Logan Public Works, Hyrum City, Nibley City, and the Cache County Building Department for unincorporated addresses. She’s fluent in English and Spanish, which matters in a service area where roughly 11% of households speak Spanish at home per recent Census ACS data, and where bilingual customer-facing service is often missing from the trade.

If you call the office, she answers. If you have a recurring tune-up coming up on your fall preseason heating maintenance, she’s tracking it. The mechanical side runs better when the administrative side runs better, and Bridget runs it.

How We Hire

Every new technician at Velox rides shotgun with Donald or Marcus for a minimum of 60 working days before any solo dispatch. The ride-along covers Logan neighborhoods one by one — you don’t diagnose a Center Street 1908 brick home the same way you diagnose a 2022 Nibley build. Continuing education runs through Bridgerland Technical College’s Workforce Development program, HVAC Excellence online modules, and manufacturer factory schools at Carrier, Trane, Mitsubishi, and Daikin. EPA 608 certifications are maintained annually. NATE recertifications run on the standard two-year specialty cycle and four-year core cycle.

The hiring filter that catches most candidates: a working knowledge of static pressure measurement and combustion analysis. We don’t hire technicians who diagnose furnaces by listening to them. We hire technicians who diagnose them by measuring them.

What This Means for Your Service Call

You know who is coming. Twenty minutes before arrival, Bridget sends a text with the technician’s name and photo. The technician arrives in a marked Velox vehicle. Diagnostic visits get diagnostic technicians — the person measuring your system is not the same person who would profit from selling you a new one. Replacement consultations are scheduled separately with Calvin, who is paid a salary, not a commission. The structural separation is on purpose. It removes the most common conflict of interest in the residential HVAC trade.

Frequently Asked Questions

Who will show up at my Logan home for a Velox service call?
One of three field technicians: Donald Arnold (owner, complex diagnostics and historic-district hydronic work), Marcus Reyes (service manager, heat pumps and refrigerant work), or Annika Jorgensen (senior installer, new system commissioning and ductwork). Roughly 20 minutes before arrival, Bridget Castro in the office sends a text with the assigned technician’s photo, name, and vehicle description. Velox doesn’t subcontract residential service calls.
What certifications do your technicians hold?
All field technicians carry EPA Section 608 Universal certification for refrigerant handling (covering legacy R-22, R-410A, and the 2025-mandated R-454B). NATE specialty certifications across the team include Air Conditioning Service, Air Distribution, Gas Heating Service, Gas Heating Installer, Heat Pump Service, and HVAC Efficiency Analyst. The company operates under Utah DOPL HVAC contractor license #10234567-5501. Continuing education hours are logged annually through DOPL, NATE, and manufacturer factory training programs at Carrier, Trane, Mitsubishi Electric, and Daikin.
Are your technicians background checked?
Yes. Every Velox employee passes a pre-employment background check through a national third-party screening provider, drug screening at hire and on a randomized post-hire basis, and a motor vehicle record check (required for company vehicle drivers). New technicians also ride with Donald or Marcus for a 60-working-day minimum before solo dispatch — not for skill verification, but because Cache Valley housing stock, water chemistry, and inversion-season demand patterns are specific enough that out-of-market experience alone doesn’t prepare a technician for the first January cold snap.
Why do you separate the comfort advisor from the installing technician?
Because the most common conflict of interest in residential HVAC is the same person diagnosing your system and quoting you a replacement. At Velox, Calvin Howell handles replacement consultations and Manual J load calculations on a salary, not commission. Field technicians measure your system and report findings; they don’t profit from selling you a new one. The structural separation removes the financial incentive to over-condemn working equipment. A 13-year-old furnace passing combustion analysis and borescope inspection gets a clean report and a maintenance recommendation, not a replacement pitch.
How long have your senior techs worked in Cache Valley?
Donald Arnold: 19 years in Cache Valley HVAC (seven at a North Main Street Carrier dealership, twelve at Velox). Marcus Reyes: 13 years. Annika Jorgensen: 8 years (Cache Valley HVAC since graduating from Bridgerland Technical College’s HVAC program in 2017). Calvin Howell: 11 years in residential trades across Cache and Box Elder counties (seven as a licensed home inspector, four as a Velox comfort advisor). Combined Cache Valley experience across the technical team: 47 years.
