Commercial Services

Commercial Heating, Cooling, Plumbing & Electrical

Partner with TOPTEC for businesses, offices, multi-family buildings, and associations across northeastern Illinois. We prioritize safety and minimize operational disruption, with dependable 24/7 service. Commercial properties take heavier use than residential ones, and when something fails, the cost is not just the repair. It is the hours you cannot trade. Where the work allows, we schedule around your operating hours. Call or text  (847) 362-0262.

Heating

Commercial heating systems run harder and longer than residential equipment, and a failure in January affects staff, customers, and sometimes stock.

• Rooftop unit (RTU) maintenance, repair and replacement
• Commercial furnace and boiler service
• Heating system installation and replacement
• Seasonal start-up and shutdown
• Preventive maintenance agreements

Cooling

Cooling failures in a commercial building are rarely just a comfort issue. Server rooms, stock and customer areas all have different requirements.

• Rooftop unit (RTU) maintenance, repair and replacement
• Commercial air conditioning service and repair
• Heat pump installation and service
• System replacement and upgrades
• Preventive maintenance agreements

Plumbing

Higher usage means components wear faster, and a plumbing failure in a commercial building can close you for the day.

• Emergency repairs
• Pipe installation and replacement
• Drain cleaning and unclogging
• Commercial water heater service
• Preventive maintenance agreements

Sewer & Drain

Commercial drain lines handle volumes residential systems never see, and in food service they handle grease as well. Blockages tend to arrive at the busiest time rather than the most convenient one.

• Sewer line repair and replacement
• Camera inspection and diagnostics
• Drain cleaning and hydro-jetting

Electrical

Electrical faults in a commercial property carry risk to staff as well as to continuity of trade. Our licensed electricians work to Illinois code and can schedule larger work outside your operating hours.

• Electrical panel service and upgrades
• Wiring installation and repair
• Lighting installation
• EV charger installation
• Generator installation and service
• Electrical safety inspections

Indoor Air Quality

Air quality affects staff comfort, productivity, and, in some premises, compliance. Commercial buildings are often sealed more tightly than homes, which means the air inside recirculates rather than refreshes.

• Air duct cleaning
• Ductwork installation and repair
• Ventilation assessment and improvement
• Filtration and air purification systems
• Humidity control

Commercial Maintenance Agreements

A scheduled maintenance agreement is usually the better option for a commercial property. It catches problems during your quiet periods rather than during service, and it gives you a known point of contact rather than a search for whoever can attend fastest.

Agreements can cover any combination of the above, and we will build one around your property and your operating hours.
