Therma Tech Inc

Therma Tech Inc operates as a licensed HVAC contractor serving San Jose and surrounding Bay Area communities including Milpitas and Fremont. Backed by 215 customer reviews with an exceptional 4.9-star average rating, the company has built its reputation on honest assessments and transparent pricing. Owner Henry leads a team of certified technicians who handle everything from routine maintenance to complete system replacements, prioritizing clear communication throughout every job.

What distinguishes Therma Tech from competitors is their commitment to straightforward advice. Unlike contractors who rely on scare tactics to win business, this team evaluates each system honestly, even telling customers when repairs beat replacements. They pass manufacturer rebates directly into quoted prices, eliminating paperwork headaches for homeowners. The crew includes Miguel, known for patient thermostat diagnostics, and Lar, John, and Frances who completed a full heat pump installation in just four days including HOA approval.

Customers consistently highlight specific technicians who turned stressful situations manageable. When Ning Ye's previous contractors claimed a cracked heat exchanger threatened carbon monoxide exposure, Therma Tech examined the system and provided an honest assessment, aged and poorly installed initially, but not dangerous. Rox Far called for a thermostat issue, and Miguel refused to leave until the problem was fully resolved. Chris Yuan's review names the entire crew, Lar, John, Frances, and Henry, for completing a heat pump replacement with remarkable efficiency.
