Livonia Contractor Logs 10+ Years of ENERGY STAR Installs

Livonia HVAC Contractor Marks Over a Decade of ENERGY STAR Certified Installations in Metro Detroit

Livonia, United States – May 20, 2026 / OnPoint HVAC /

OnPoint HVAC, a residential heating and cooling contractor based in Livonia, has earned recognition from area homeowners and industry peers for its record of ENERGY STAR certified system installations throughout Metro Detroit. The acknowledgment reflects the company’s consistent application of engineering-grade installation methods – including load calculations, custom ductwork design, and airflow balancing – across more than a decade of service to Michigan residents.

Engineering Standards Behind Every Installation

OnPoint HVAC has built its reputation on a methodology that distinguishes it from standard replacement contractors. Rather than defaulting to equipment swaps, the company performs detailed load calculations before specifying any system, ensuring the selected unit matches the actual heating and cooling demands of each home. This approach, applied to every ENERGY STAR HVAC Livonia MI project the company undertakes, is designed to eliminate common installation errors that reduce efficiency and shorten equipment life.

The company installs Tempstar and AirQuest systems – both members of the Carrier family of brands – across its full service territory, which includes Livonia, Berkley, Birmingham, Canton, Farmington Hills, Northville, Novi, Plymouth, Royal Oak, and Southfield. As a licensed Carrier HVAC installer Metro Detroit residents have relied on for complex residential projects, OnPoint HVAC has completed installations ranging from straightforward equipment replacements to whole-home duct modifications.

George Petrentzev on Long-Term Energy Savings

Founder George Petrentzev brings 20 years of HVAC experience to each project, with a focus on the engineering decisions that determine whether a system performs as rated over its full service life. His background informs the company’s strict adherence to manufacturer installation specifications and its use of airflow balancing as a standard post-installation procedure.

“ENERGY STAR certified equipment can deliver up to 15 percent in annual energy savings compared to standard systems, but only when the installation is done correctly,” said George Petrentzev, Founder of OnPoint HVAC. “Every Tempstar AirQuest installation Michigan homeowners request from us starts with a load calculation – not a guess – so the equipment we install actually performs to the efficiency ratings on the label.”

Petrentzev’s approach has produced a consistent record of referrals within the communities the company serves, with homeowners in Farmington Hills and Northville citing measurable reductions in utility costs following completed installations.

Certified Equipment Across the Carrier Family

OnPoint HVAC’s work with Tempstar and AirQuest equipment reflects the company’s focus on Carrier-family systems, which share engineering platforms, replacement parts, and certified technician training protocols. Both product lines carry ENERGY STAR ratings across multiple configurations, giving homeowners access to efficiency-certified options at different price points. OnPoint HVAC carries full licensing and insurance coverage across its Metro Detroit service area and offers free estimates to homeowners evaluating system replacement or new installation.

The recognition OnPoint HVAC has received comes at a time when Michigan homeowners face increased scrutiny of home energy costs, particularly following multiple winters with extended periods of sub-freezing temperatures across the region. Properly sized and installed ENERGY STAR HVAC Livonia MI equipment has been shown by the U.S. Environmental Protection Agency to reduce energy use for heating and cooling by a measurable margin compared to non-certified alternatives – a factor OnPoint HVAC addresses during its free on-site estimate process.
