Hexagon Air & Heat is a Houston HVAC contractor identifying as both Latino-owned and veteran-owned, serving residential and commercial customers 7 days a week from 7 AM to 7 PM. With a 4.9-star rating across 40 reviews, the company has built a strong reputation through fast response, honest diagnosis, and consistent technician quality. Financing and membership plans are available.

Services cover the full HVAC spectrum: AC installation, repair, maintenance, and drain line cleaning; ductless mini-split systems; heat pump installation, repair, and maintenance; furnace installation, repair, and maintenance; thermostats; and air quality improvements including duct cleaning, attic insulation, attic solar fans, and attic door insulators.

Isaac — the owner or lead technician — is named in six of eight sampled reviews. He consistently appears across both residential and commercial calls, often responding within the hour after contact. In one residential furnace case, a customer called assuming they needed a new furnace. Isaac's first response was to send a tech to assess before quoting — a deliberate anti-upsell approach — though the inspection confirmed a new furnace was necessary. He had the quote ready quickly and the replacement completed the next day. Ryan, the installation technician, explained every detail of the job throughout the process.

In commercial settings, Isaac was on-site within an hour of contact to troubleshoot a failing AC system, identified the faulty part, and completed the repair quickly. One reviewer said Hexagon was "a breath of fresh air" for a commercial space. Saturday service within an hour of scheduling is documented in a residential case as well. For Houston homeowners and businesses seeking a veteran- and Latino-owned HVAC contractor with responsive service and a culture of honest diagnosis first, Hexagon Air & Heat is a strong candidate.
