Preventive maintenance programs for commercial and industrial HVACR systems, built around your facility, your operations and your budget.

Commercial HVAC maintenance is the scheduled inspection, cleaning, testing and adjustment of a building's heating, cooling, ventilation and refrigeration systems so they run reliably and efficiently.

When a commercial HVAC system goes down, the cost goes well past the repair bill. Production stops, tenants call, and emergency repairs get priced at emergency rates. A system that runs without regular maintenance also wastes energy every day and wears out years before it should.

BC Ten Air is a commercial HVACR contractor serving facility managers, property managers and building owners across Southeast Michigan. Our preventative maintenance programs catch minor issues before they become costly repairs, help reduce energy consumption and extend the life of the commercial equipment your business already paid for. We have served commercial and industrial clients in Metro Detroit since 1982.

Commercial HVACR Systems We Maintain

Our technicians maintain the full range of commercial and industrial HVACR systems. Each visit follows a documented checklist, so you know exactly what was inspected, cleaned, adjusted or replaced.

Heating and Air Conditioning Equipment

We service rooftop units, split systems, air handlers, chillers and the controls that run them. Regular maintenance on heating and cooling systems keeps temperatures stable, protects indoor air quality and stops small faults from shutting down a zone or an entire building.

Cooling Towers

Cooling tower maintenance covers fill and basin cleaning, fan and drive inspection, and checks on water flow and distribution. A neglected tower loses heat-rejection capacity, which forces chillers to work harder and drives up energy consumption.

CSD-1 Boilers

We inspect and test the controls and safety devices required under ASME CSD-1 for automatically fired boilers, including flame safeguards, limit controls and low-water cutoffs. Keeping CSD-1 boilers in compliance protects your people, your property and your insurance coverage.

Industrial Boilers

Industrial boiler maintenance includes burner tuning, combustion analysis, water-side and fire-side inspection, and checks on safety and operating controls. Clean, well-tuned boilers burn less fuel and hold up longer under heavy process loads.

Refrigeration Systems

We maintain commercial and industrial refrigeration systems, from compressors and condensers to evaporators and controls. Early detection of refrigerant leaks, oil problems or failing components protects product, supports compliance and prevents unplanned downtime.

For new systems, retrofits or capacity changes, see our HVACR system upgrades and HVACR equipment pages. For a breakdown that can't wait, our HVACR service and repair team is available around the clock.

What a Preventative Maintenance Visit Includes

A complete preventative maintenance visit goes beyond changing filters. Depending on the system, our technician will:

Inspect and tighten electrical connections, and test starter coils and contactors
Clean condenser and evaporator coils, since dirty coils reduce heat transfer and raise operating cost
Check refrigerant charge and test for leaks
Clear condensate drains and pans to prevent water backups and damage
Clear debris from outdoor and rooftop units so they don't overheat
Lubricate bearings and check belts, pulleys and couplings
Verify thermostat and control calibration and sequence of operation
Inspect accessible ductwork and dampers for air loss
Document findings, with repair recommendations and pricing before any work is done

Signs Your HVAC System Needs Professional Maintenance

Even with a maintenance plan in place, watch for these warning signs between service calls:

Inconsistent heating or cooling. Hot and cold spots, zones that never reach set point, or a system that short-cycles usually point to control, airflow or refrigerant problems.
Rising energy costs. If utility bills climb without a change in occupancy or weather, dirty coils, worn belts, failing economizers or drifting controls are often behind the energy waste.
Frequent breakdowns. Repeated service calls on the same units mean root causes are not being addressed. A preventive program gives you the records to make informed decisions about whether to repair or replace.
Unusual noises or odors. Grinding, squealing, rattling, burning smells or musty air can signal failing bearings, electrical problems, combustion issues or microbial growth. Call a technician before a minor issue becomes a shutdown.

Industries We Maintain For

Every facility type puts different demands on its HVAC system. We tailor each maintenance program to the operations it supports.

Apartments and senior living: Apartment complex HVAC maintenance means many units, occupied spaces and residents who depend on steady temperatures, so we plan work to minimize disruption.
Healthcare: Healthcare facilities need tight control of temperature, humidity and air quality, along with documentation for inspections.
Automotive: Automotive plants run process cooling, makeup air and paint-area ventilation where downtime stops the line.
Energy: Energy sites rely on critical heating and cooling for control rooms and systems that cannot go offline.
Corporate: Corporate offices need comfortable, quiet buildings that support employee productivity and keep tenants satisfied.
Chemical: Chemical facilities require HVACR maintenance that accounts for corrosive environments, ventilation requirements and strict safety procedures.

Commercial HVAC Maintenance FAQs

How often should a commercial HVAC system be serviced?

Most commercial HVAC systems need professional maintenance at least twice a year, typically before the heating and cooling seasons. Some components need more frequent attention: filters, starter coils and contactors, and control set points are usually checked quarterly. High-use, process-critical or industrial systems may need monthly visits.

What does a commercial HVAC maintenance contract include?

A maintenance agreement defines the scope of work, the systems covered, visit frequency and response times. Most include scheduled inspections, cleaning, lubrication, filter changes, control checks and written reports with follow ups on any deficiencies. Some also include priority emergency service and discounted repair pricing.

How much does a commercial HVAC maintenance contract cost?

Pricing depends on the number and type of units, the age and condition of each system, visit frequency and what the agreement covers. We walk your site and build a maintenance plan that fits your facility and budget, so you only pay for the work your building needs.

What is the difference between preventive and reactive maintenance?

Reactive maintenance waits for a system to fail and then repairs it, often at emergency rates and with unplanned downtime. Preventive maintenance follows a set schedule to inspect, clean and adjust systems so problems are found early. Predictive maintenance goes a step further, using monitoring data to spot failures before they happen. Over the long run, planned programs reduce emergency repairs and save money.

What does a CSD-1 boiler inspection involve?

ASME CSD-1 covers the controls and safety devices on automatically fired boilers. An inspection includes testing flame safeguards, operating and limit controls, low-water cutoffs, gas pressure switches and safety shutoff valves, then documenting the results. Michigan facilities should confirm their specific inspection requirements with their insurer and local authority.

How does regular maintenance affect energy costs?

Clean coils, correct refrigerant charge, calibrated controls and properly tensioned belts let a system deliver the same heating and cooling with less energy. Regular maintenance helps reduce energy consumption and lower utility bills, and it flags drifting controls before they cause energy waste.

Do you offer industrial HVAC maintenance?

Yes. We maintain industrial boilers, process cooling, refrigeration systems, cooling towers and makeup air units for manufacturing, automotive, energy and chemical facilities, with schedules built around production.

Do you provide emergency repairs if something fails between visits?

Yes. Our 24-hour emergency line, (248) 348-1360, connects you with a technician any time of day. Maintenance customers also benefit from the records we keep on their systems, which speeds up diagnosis.
