Make-Up Air & Ventilation
Commercial kitchen ventilation done wrong fails health inspections and burns through energy. AK designs, installs, and services make-up air units for restaurants, manufacturing, and any space with a powered exhaust hood. Balanced airflow keeps your hood compliant, your dining room comfortable, and your gas-fired equipment safe.

Commercial Maintenance Plans
Commercial mechanical maintenance contracts put cost-of-downtime on a schedule instead of a panic. Quarterly visits, seasonal change-over, written compliance reports, and priority response when something does break. One contract covers HVAC, refrigeration, and generators if you've got all three on the same property.
- Quarterly preventive maintenance visits
- Seasonal heating/cooling changeover
- Written inspection reports for compliance audits
- Priority same-day response for contract clients
- Bundled HVAC + refrigeration + generator contracts

Clark's Tip · Lowering Energy Bills
Run a setback schedule after hours
Closed nights and weekends? Set the thermostat to drift 8-10°F when nobody's there. Most commercial spots save $40-80 per zone per month with that one change — and your team doesn't feel a thing when the building wakes up.
