Commercial HVAC has been Oak Grove's home turf since day one. We keep your building comfortable and your business running with repair, maintenance and installation planned around your operation.
A commercial system down means lost business, uncomfortable customers and staff, and sometimes spoiled inventory. Oak Grove has kept Livingston and Oakland county businesses running since 1995, with the same straight talk and craftsmanship we bring to homes.
From rooftop units and radiant heating to full replacements, we assess honestly, recommend what protects the asset, and work around your hours so disruption stays minimal.
Repair and emergency service
Rooftop units, split systems, radiant and underfloor heating, and controls. We diagnose fast and carry the experience to fix commercial equipment other shops will not touch.
Preventive maintenance
The cheapest commercial breakdown is the one that never happens. Scheduled maintenance catches failing parts, dirty coils and drifting controls before they shut you down, and extends the life of the equipment.
Installation and replacement
When a system is past its life, we plan and install the replacement around your business, with clear timelines and clean work, so you keep operating while we keep you comfortable.
How commercial work differs from a house
Commercial HVAC is where Oak Grove started, and it is a different animal from residential. The equipment is bigger and often on the roof, the controls are more involved, and the stakes are higher: when a system goes down it is not just discomfort, it is lost sales, unhappy customers and staff, and sometimes spoiled product. The work has to be right and it has to be fast.
We handle rooftop units, split systems, radiant and underfloor heating, and the controls that tie them together. Thirty years in has taught us to fix commercial equipment other shops turn down, and to schedule the work around your hours so we are not shutting you down to keep you comfortable.
A maintenance plan that pays for itself
The cheapest commercial breakdown is the one that never happens. Coils clog, belts wear, contactors pit, and controls drift, and every one of those gives warning before it fails if someone is looking. Scheduled maintenance catches the small problems on your calendar instead of on the hottest or coldest day of the year.
A plan also extends the life of expensive equipment and keeps efficiency up, which shows on the utility bill. We tailor the visits to your building and your season rather than selling a one-size checklist, and we keep records so you know exactly what has been done.
Rooftop units, radiant heat and controls
Rooftop package units do the heavy lifting for a lot of local businesses, and they live a hard life exposed to Michigan weather year round. We service and replace them, and we know the radiant and underfloor systems that warehouses, shops and some newer builds rely on, which is specialized heating a lot of contractors avoid.
When a system is genuinely past its life, we plan the replacement around your operation with clear timelines, so you keep running while we get the new equipment in and commissioned. Same straight talk we give homeowners, scaled to a building.
