Meet the Purisync Team
Purisync runs lean. Five technicians, one service coordinator, one apprentice. Every name below answers calls in person, runs diagnostics with calibrated instruments, and signs the work order. We don’t subcontract. We don’t dispatch service through a third-party call center in another state. The technician who shows up at your house is on payroll, NATE-certified or apprenticing under someone who is, EPA-licensed for the refrigerants we handle, and accountable to James Eason directly. That model limits how many jobs we can take in a week — and it’s also the reason a 14-year-old Lennox passing combustion analysis gets a clean inspection report instead of a $9,000 replacement quote.
James Eason — Owner and Lead Technician
James founded Purisync in 2014 after eight years at a Carrier dealership on Lindbergh Boulevard in Sunset Hills. He holds St. Louis County Mechanical Contractor License #MC-2014-08439-STL, Kirkwood Business Registration #BL-2014-1187, and EPA Section 608 Universal certification #608U-2014-385721 covering R-22, R-410A, and R-454B. NATE-certified in Air Conditioning Service, Air Distribution, and Gas Heating Service (NATE ID #4587921). ACCA Manual J, S, and D coursework completed through HVAC Excellence in 2010. RSES Class HE member since 2012. PHCC of Greater St. Louis member since 2014.
James personally runs every emergency call after 10 p.m. and supervises every installation over $8,000. He grew up in Affton, graduated from Affton High School in 2003, and lives in north Kirkwood. Most Saturday mornings, he’s at the Kirkwood Farmers Market with his kids.
Marcus Pulliam — Service Manager
Marcus joined Purisync in 2017 after four years at a Mehlville HVAC contractor and two years as a maintenance technician at SSM Health St. Mary’s Hospital in Richmond Heights. A 2011 graduate of Ranken Technical College’s HVAC Engineering Technology program, he holds NATE certifications in Air Conditioning Service, Heat Pump Service, and Gas Heating Service. EPA Section 608 Universal certified. ACCA Manual J certificate completed in 2015.
He runs all heat pump installations and the diagnostic calls that defeated the previous contractor — the ones that come in as “the AC’s not cooling” and turn out to be a 0.4 ohm winding-to-ground short on the compressor, a TXV stuck at 60% capacity bleeding superheat, or a stuck reversing valve on a heat pump that’s been heating in cooling mode all summer. Marcus carries a Fluke 902 FC clamp meter, a Testo 510i differential manometer, a Bacharach Fyrite Insight Plus combustion analyzer, and a Yellow Jacket TitanHV digital gauge set on every truck call. He lives in Affton and runs the south-of-I-44 service zone.
Daniel Ortega — Lead Installer
Daniel joined in 2018 after five years at a Webster Groves residential installation company. He runs every complete system replacement — furnace and condenser swaps, full ductwork retrofits, and the historic district installations that need PVC sidewall venting because the original unlined masonry chimney can’t carry a 90%+ AFUE condensing furnace flue. NATE-certified in Air Distribution and Air Conditioning Service. ACCA Manual D Quality Installation certificate completed in 2019. EPA Section 608 Universal.
Daniel’s specialty is the 1920s and 1930s Kirkwood housing stock where original 6×10 trunk ducts need replacement to bring static pressure under 0.5" WC for a modern variable-speed ECM blower. He’s installed in every Kirkwood historic district at this point — Meramec Highlands, Central Place, Jefferson-Argonne, Savoy, Craig Woods. He lives in Crestwood with his wife and twin daughters and runs the central service zone.
Brandon Reeves — Indoor Air Quality Specialist
Brandon joined in 2019 to run the indoor air quality side of the business — whole-home humidification, MERV upgrade evaluations, ERV and HRV installation in tight-envelope new builds, UV-C coil treatment, and the post-renovation duct-cleaning projects where construction dust has migrated into supply registers and return plenums. NATE-certified in Air Distribution. ACCA Indoor Air Quality certificate. BPI Building Analyst certification #BA-2018-22156 for whole-home pressure diagnostics and combustion safety testing.
Brandon designs the humidifier service intervals around the 10–12 gpg Missouri American Water supply: steam canister replacement at 1,800 runtime hours instead of the box-recommended 2,400, evaporative pads at 14 months instead of 24, condensate-pump strainer service every six months on dehumidifiers. He lives in Webster Groves, walks to work the days he isn’t on a truck, and handles the IAQ scope on every install over $5,000.
Theresa “Tess” Hollings — Service Coordinator
Tess runs dispatch, scheduling, permit pulls through Kirkwood Public Works and the St. Louis County Department of Public Works, warranty registration with manufacturers, and customer communications. Fifteen years of administrative work in St. Louis County skilled trades, six of them with Purisync. PHCC office administration training completed in 2019.
Every callback and confirmation goes through Tess — including the 6 a.m. dispatch when a no-heat call comes in overnight, the post-install permit close-out coordination with the county inspector, and the warranty paperwork submitted to Carrier, Trane, Lennox, or whichever manufacturer’s equipment we just installed. She grew up in north Kirkwood, has lived in the same neighborhood since 2011, and knows half the customers personally before they call.
Anthony Whitcomb — Apprentice Technician
Anthony is in his second year as an apprentice under James, currently enrolled in the second-year HVAC Engineering Technology program at Ranken Technical College. He holds EPA Section 608 Type II certification with the Universal exam scheduled for spring 2027. NATE Air Conditioning Service exam scheduled for Q4 2026.
Anthony rides with James on weekday service calls, runs second-tech support on installations, and handles the spring and fall maintenance tune-up rounds — coil cleaning, capacitor checks, refrigerant charge verification, condensate line clearing. He grew up in Webster Groves, graduated from Webster Groves High School in 2023, and plans to test for Missouri master mechanical certification in 2028 after completing his Ranken program.
How the Team Operates
Diagnosis Before Quoting
Every service technician carries calibrated combustion analyzers (Bacharach Fyrite Insight Plus or Testo 320), a digital manometer for gas pressure and static pressure measurement, a Fluke clamp meter rated to 1000A DC for compressor inrush analysis, a Hawkeye inspection borescope for heat exchanger and evaporator coil inspection, and a FLIR ONE Pro thermal imaging camera for duct leak and refrigerant-line surveys. We measure first, then quote. Photos and meter readings go on the work order. The customer sees what we saw.
Continuing Education and Code Cycle Training
Every technician completes a minimum of 24 hours of continuing education annually, with NATE recertification on a five-year cycle. Marcus and Daniel attended the 2025 R-454B refrigerant transition training through Carrier University in St. Charles. Brandon attended the 2024 ACCA Manual J/S/D refresh through HVAC Excellence. James completes the annual St. Louis County code-update training each March before the 2018 IMC and 2018 IRC code-cycle renewals with Missouri amendments. Tess attends the annual Missouri Department of Revenue contractor tax compliance update. We pay for all training. We pay for all tools. We pay for all certification exams.
Local Hiring and Dispatch Logic
Every Purisync technician lives within 12 miles of the Kirkwood office. That isn’t a marketing pitch — it’s how the dispatch math works. A no-heat call at 4 a.m. in Webster Groves is on a technician’s truck inside 20 minutes when the closest tech sleeps in Affton. We hire from Ranken Technical College’s HVAC Engineering Technology program directly, with apprenticeship slots reserved for graduates of Webster Groves High School, Kirkwood High School, and Affton High School where applications match the role.
