About
Marcus has been turning wrenches on HVAC systems in the Texas heat for 14 years. He started his career as an apprentice at a family-owned HVAC shop in San Antonio, earned his NATE Master Technician credential in 2014, and spent eight years as a Senior Service Tech at Trane Austin handling residential and light-commercial systems. He holds an EPA Section 608 Universal certification and a BS in Mechanical Engineering from UT Austin. Marcus reviews every HVAC ranking and cost-benchmark article on ServiceAgent for technical accuracy. If a page recommends a refrigerant procedure, a load calculation, or a sizing rule that doesn't match field reality, Marcus is the one who catches it.
