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?

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.
