Trusted HVAC Installation in Livonia, MI - OnPoint HVAC


Livonia's Trusted HVAC Installation Contractor

When Livonia homeowners need reliable, lasting HVAC installation, they call the company that lives and works right here in the community. OnPoint HVAC is a licensed, family-owned, engineer-led HVAC contractor based in Livonia, Michigan — not a national franchise dispatching technicians from out of town, but a neighbor who understands this community, these homes, and the demands of a Michigan winter. Founded by George Petrentzev, a licensed mechanical engineer, OnPoint HVAC brings a level of technical precision and personal accountability to every installation that larger companies simply cannot match.



Michigan's climate does not give homeowners much room for error. Livonia summers push heat indices well above 90°F, and Wayne County winters regularly bring sub-zero wind chills that test every component of a home's heating system. An undersized furnace, an improperly charged air conditioner, or a duct system that was never engineered for the home's layout can mean discomfort, high utility bills, and equipment that fails before its time. OnPoint HVAC was built to solve exactly that problem — with engineered system design, quality equipment, and installation done right the first time.

HVAC Installation Services in Livonia, Michigan

OnPoint HVAC installs complete residential heating and cooling systems throughout Livonia and the surrounding Metro Detroit area. Every installation begins with a load calculation and system design, ensuring the equipment selected is the right size and configuration for the home — not simply whatever is on the truck.


Furnace Installation From high-efficiency gas furnaces to two-stage and modulating systems, OnPoint HVAC installs furnaces that are sized correctly, sealed properly, and calibrated for maximum efficiency. A correctly installed furnace in a Livonia home can deliver decades of reliable heat through even the harshest Michigan winters.


Air Conditioning Installation A new central air conditioner is only as effective as its installation. OnPoint HVAC sizes AC systems to the home's actual cooling load, verifies refrigerant charge, and confirms airflow through every register — so the system runs efficiently from day one. Proper AC installation Livonia MI homeowners can rely on means lower electric bills and a longer equipment life.


Heat Pump Installation Modern cold-climate heat pumps are now a viable primary heating and cooling solution in Michigan. OnPoint HVAC installs both air-source and dual-fuel heat pump systems, pairing them with backup heating where the local climate demands it. George's engineering background ensures every heat pump system is matched to the home's envelope and performance goals.


HVAC System Replacement Replacing an aging furnace or air conditioner is one of the highest-impact upgrades a Livonia homeowner can make. OnPoint HVAC guides each homeowner through equipment selection, explains efficiency ratings in plain terms, and completes the replacement with a clean, code-compliant installation — no shortcuts.



Ductwork Installation and Repair A high-efficiency system paired with leaky or undersized ductwork delivers mediocre results. OnPoint HVAC designs and installs duct systems that distribute conditioned air evenly throughout the home, and repairs existing ductwork that is losing capacity to leaks, disconnections, or poor original design.

Frequently Asked Questions — HVAC Installation in Livonia, MI

  • How much does HVAC installation cost in Livonia, MI?

    The cost of a new HVAC system in Livonia typically ranges from $4,500 to $12,000 or more, depending on the type of equipment (furnace only, AC only, or a combined system), efficiency rating, and whether ductwork modifications are needed. OnPoint HVAC provides free, detailed estimates so homeowners know exactly what they are paying for before any commitment is made. Request a free estimate to get a number specific to the home.


  • Do I need a permit for HVAC installation in Livonia?

    Yes. The City of Livonia requires mechanical permits for new HVAC equipment installations and significant system replacements. OnPoint HVAC handles the permitting process as part of every installation, ensuring the work is inspected and code-compliant. Homeowners should be cautious of any HVAC contractor Livonia MI that suggests skipping the permit — it creates liability and can affect home resale.

  • How long does a new HVAC installation take in Livonia?

    Most standard furnace or air conditioner replacements are completed in a single day — typically four to eight hours depending on the complexity of the system and whether any ductwork modifications are needed. Full system replacements involving both heating and cooling equipment may require six to ten hours. OnPoint HVAC schedules installations to minimize disruption and leaves the home clean and fully operational the same day.

  • How do I know what size HVAC system my Livonia home needs?

    System sizing is determined by a Manual J load calculation, which accounts for the home's square footage, insulation levels, window area, ceiling height, and local climate data for the Livonia / Wayne County area. This is a critical step that many contractors skip in favor of simply matching the size of the old equipment. OnPoint HVAC performs a proper load calculation on every project — it is the only way to guarantee that the new system will perform as intended and deliver the efficiency ratings printed on the equipment label.
