OnPoint HVAC Expands to 24/7 Emergency Repairs Across Metro Detroit After 20 Years of Field Experience

Livonia, United States – June 3, 2026 / OnPoint HVAC /

OnPoint HVAC, a licensed, family-owned heating and cooling contractor based in Livonia, Michigan, has officially expanded its service offerings to include 24/7 emergency HVAC repair across Metro Detroit. The move, driven by founder George Petrentzev’s two decades of hands-on field experience, positions the company to respond to heating and cooling failures at any hour, in any season, across the broader Metro Detroit region.

A Founder-Led Expansion Built on 20 Years of Field Experience

George Petrentzev launched OnPoint HVAC with a straightforward premise: HVAC work should be done right the first time, by technicians who understand the engineering behind the equipment they service. With 20 years of field experience, Petrentzev has built the company around what he describes as an engineering-first approach – diagnosing root causes rather than applying quick fixes that leave homeowners facing repeat failures.

The expansion into around-the-clock emergency service reflects that same philosophy. Metro Detroit homeowners deal with harsh Michigan winters and humid summers, and a failed furnace or air conditioner rarely waits for business hours. OnPoint HVAC’s new availability structure means that when a system goes down at midnight or over a holiday weekend, a trained technician is reachable and ready to respond.

“We built this company on the idea that homeowners deserve the same quality of service at 2 in the morning as they do at 2 in the afternoon,” said George Petrentzev, Founder of OnPoint HVAC. “Expanding to 24/7 HVAC service is a direct response to what Metro Detroit families have been asking for – fast, reliable help from someone they can trust, not a rushed patch job from whoever happens to be available.”

Fast Response Times and Trained Technicians at the Core

The emergency hvac repair service is designed around response speed without compromising diagnostic quality. OnPoint HVAC technicians are trained to assess the full scope of a system problem before recommending repairs, a process Petrentzev credits with reducing unnecessary part replacements and repeat service calls.

For homeowners dealing with a sudden system failure, the difference between a fast, accurate diagnosis and a hasty one can mean the difference between a single repair visit and multiple callbacks. OnPoint HVAC’s technicians are expected to arrive prepared, with the knowledge and tools to address the most common emergency scenarios on the first visit.

Family-Owned Values Behind a Broader Service Footprint

As a family-owned business, OnPoint HVAC operates with a level of accountability that Petrentzev says shapes every service call. Technicians represent the company’s reputation directly, and the family-business structure means there is no large corporate layer separating ownership from field operations. That connection, Petrentzev argues, keeps quality standards consistent across every job.

The expansion of hvac repair metro detroit coverage is also accompanied by an emphasis on proactive maintenance. OnPoint HVAC encourages homeowners not to wait for an emergency to schedule service. Identifying worn components, refrigerant issues, or airflow problems before they become failures reduces the likelihood of a middle-of-the-night breakdown and extends the lifespan of the equipment. The company offers free estimates, giving homeowners a low-barrier entry point to getting their systems evaluated before a problem escalates.
