A reliable HVAC system is vital for your restaurant. It keeps patrons comfortable no matter the season and makes it easier for your staff to do their job both in and out of the kitchen. This guide will ensure you have the right setup for your establishment.

Commercial HVAC vs. Residential Equipment

Traditional residential HVAC units rely on a simple two-step process that pulls outdoor air inside and conditions it to desired temperatures, based on the season. Restaurant heating and cooling systems must be more complex to accommodate the size and ventilation needs of the establishment. 

Commercial HVAC systems must have enough air exchange between the indoor and outdoor units. The wrong amount from too much or not enough leads to poor air quality and disruptions such as drafts and slamming doors. Gases, grease, and smoke released during cooking—if not vented properly—can mean stagnant, unpleasant air may filter into your dining area. It can also be dangerous since grease and gases are combustible.

Hood systems and ductwork play a big part in completing the equipment. They also make the air exchange more efficient, which reduces energy consumption as you run your kitchen.

Issues & Considerations

A common issue with restaurant HVAC is improper ductwork. Ducts must be sealed correctly and made from a durable, commercial-grade steel gauge that can handle a higher amount of air pressure and ventilation. Also, hoods in the kitchen area must be placed correctly over appliances, so the air circulates, and gases and smells filter out. This includes all stoves as well as fryers, grills, and griddles. Give cooking equipment proper clearance so there is no buildup of dangerous substances that can ignite or degrade air quality.

Because of the environment of a commercial kitchen, temperatures tend to fluctuate more than in a home. This means your unit must meet the demands so that employees and customers do not feel overheated as kitchen heat rises.

Opt for zones that automatically adjust to preset settings, so that kitchen comfort doesn’t interfere with your patron’s enjoyment. Your kitchen temperatures can also be set to accommodate peak cooking times while your dining room remains constant. Consider adding equipment that features variable exhaust controls so that they reduce during downtime and rise when necessary.
