Commercial HVAC maintenance on rooftop packaged units
A commercial HVAC maintenance visit on the rooftop packaged units serving a business in Shorewood, one of our technicians working the units mid-service.
How We Saved a Commercial Client $17,000
A few years back, we got a call about a 15-year-old Carrier rooftop unit at a Plymouth office building that had lost most of its cooling capacity. The building manager had already been quoted a full replacement. We went out, ran a thorough diagnostic, and found a refrigerant leak caused by a thin spot where two metal surfaces were rubbing together. We repaired the weak spot, sealed the system, and recharged it. The unit ran properly. The client kept $17,000 in their pocket. That's not a lucky outcome — that's what happens when you actually diagnose the problem instead of defaulting to replacement. It's the reason repair-first isn't just a slogan for us. It's how we operate on every commercial HVAC service call.
What Our Quarterly Maintenance Contracts Cover
Unplanned HVAC failures cost businesses more than the repair itself — they cost productivity, comfort, and sometimes customer-facing disruptions. A quarterly maintenance contract keeps those surprises off the table. Each visit covers a filter change and a full system check on your heating and cooling equipment, so developing issues get caught before they turn into a breakdown. We build the maintenance schedule around your operation, not ours. If you can't have service done during business hours, we work around it.
Flexible Scheduling Built Around Your Business Hours
Details below
We offer after-hours and weekend appointments because commercial clients can't always shut down operations for HVAC servicing during the day. We also provide 24/7 emergency repair when something fails unexpectedly — nights, weekends, and holidays. For non-emergency scheduling, we offer a two-hour arrival window so you're not burning half a workday waiting on a technician. Every installation job involves the same established two-person crew, and Jason personally inspects every completed installation before we call a job finished.

Commercial HVAC Replacement — When It Actually Makes Sense
We don't push replacement. But there are situations where it's the right call: when repair costs approach or exceed 50 percent of replacement value, when parts are no longer available, when a system is so inefficient that energy costs alone justify the switch, or when repeated failures signal a systemic problem rather than isolated wear. When replacement is the right answer, we handle the full commercial installation, including rooftop unit replacement for flat-roof commercial properties. As an AirQuest Elite Dealer, qualifying installations include manufacturer limited warranty coverage plus two additional years of No Hassle Replacement coverage beyond the standard terms. We'll give you the honest comparison — repair cost vs. replacement cost vs. long-term operating cost — and let you decide.

Indoor Air Quality and Specialty Commercial Equipment
Beyond standard heating and cooling, we service the equipment that often gets overlooked in commercial buildings. Makeup air handlers are critical in commercial kitchens, manufacturing spaces, and high-occupancy buildings — and they're a service most residential HVAC companies can't touch. We also handle air exchanger service and commercial humidifier installation. If your building has dry air complaints in winter or ventilation issues year-round, those are solvable problems. We'll tell you what's actually causing it before we recommend equipment.

Rooftop maintenance · Chanhassen
Jason and his team, did routine maintenance on our air conditioning units. Then put new belts on some of our air moving equipment. He found that one of our electric motors was seized and ordered a new one. That will go in soon. Great service!

Frequently Asked Questions
What exactly does HVAC mean in a commercial context? +
HVAC stands for Heating, Ventilation, and Air Conditioning. In commercial buildings, that scope often extends beyond a furnace and central AC unit to include rooftop package units, makeup air handlers, economizers, variable air volume systems, and building automation controls. Commercial HVAC systems are typically engineered around square footage, occupancy load, ventilation requirements, and code compliance in ways that residential systems aren't.
How often does a commercial HVAC system need maintenance? +
Most commercial systems benefit from quarterly maintenance visits rather than the annual tune-up that's standard for residential equipment. Commercial units run harder, accumulate more wear, and serve spaces where a breakdown affects employees, customers, or production. Quarterly service means a filter change and a full system check four times a year, catching developing issues before they become failures. We structure maintenance contracts around your system's actual demands, not a one-size schedule.
Can a commercial rooftop unit be repaired instead of replaced? +
Often, yes. Rooftop units are repairable for most common failure modes: refrigerant leaks, failed compressors, heat exchanger issues, economizer malfunctions, and worn belts or bearings. We repaired a 15-year-old Carrier rooftop unit for a Plymouth office building that another contractor had quoted for full replacement. The actual issue was a refrigerant leak from metal-on-metal wear. After repair, the system ran correctly and the client avoided a $17,000 replacement cost. We diagnose first, every time.
What's included in a commercial HVAC maintenance contract? +
Our quarterly contracts cover a filter change and a full system check on your equipment each visit. Contract customers also receive priority scheduling and after-hours availability. We tailor the check to the specific equipment in your building — a rooftop unit and a split system have different failure points, so the technician knows what to look for on each.
Do you work on commercial HVAC systems outside normal business hours? +
Yes. We offer after-hours and weekend appointments for scheduled maintenance so your business operations aren't interrupted. For urgent failures, we provide 24/7 emergency service including nights, weekends, and holidays. If your system goes down at an inconvenient time, call (952) 847-3387 and we'll get someone out. We're fully insured on every commercial job regardless of when it's scheduled.
