Restaurant HVAC That Keeps the Kitchen Cool and the Dining Room Comfortable
A restaurant is one of the most demanding environments in commercial HVAC. You’re running high-output cooking equipment under a powerful exhaust hood, a packed dining room with its own comfort needs, and refrigeration that can’t fail without costing you product and revenue. Modern Air has serviced South Bay food-service operations since 2009, and we understand how these systems have to work together, not as separate pieces, but as one balanced building.
Make-Up Air Is the Heart of the Problem
Most restaurant comfort complaints trace back to air balance. Your kitchen exhaust hood can pull thousands of cubic feet of air per minute out of the building. If that air isn’t replaced by a properly sized make-up air unit, the building goes negative, doors are hard to open, the back door slams, combustion appliances can backdraft, and conditioned air gets dragged out of the dining room and straight up the hood. We measure exhaust rates and balance make-up air to match, so the kitchen stays workable, the hood captures smoke and grease correctly, and the front of house keeps the comfort your guests are paying for.
Kitchen Exhaust, Cooling, and Heat That Hold Up to the Line
Commercial kitchens generate enormous sensible and latent heat. We size and service rooftop units, exhaust fans, and supplemental cooling so cooks aren’t working in a sauna and your equipment isn’t fighting itself. Grease, heat, and constant runtime wear HVAC equipment far faster than in an office, so we pay attention to the things that actually fail, belts, bearings, contactors, and coils caked with kitchen grime.
Refrigeration Is Where We Started
Walk-ins, reach-ins, prep tables, and freezers are non-negotiable in food service, and refrigeration is the work our company was founded on. A failing compressor or iced-up evaporator can ruin thousands of dollars of inventory overnight. We diagnose and repair commercial refrigeration, watch for the early warning signs of trouble during maintenance visits, and respond fast when a cooler goes down. That refrigeration depth is something most general HVAC contractors simply don’t have.
Dining-Room Comfort and Zoning
The dining room has different needs than the kitchen, quieter operation, even temperatures across the space, and no cold drafts on guests near the entrance. We look at how your rooftop units and ductwork are zoned so a full house on a hot afternoon stays comfortable without freezing out the tables near the supply registers. If your layout has changed since the system was installed, we can rebalance or add zoning to match how the room is actually used.
Service Scheduled Around Your Hours
Restaurants live and die by service hours, so we work around yours. Maintenance and most repairs happen before you open, after you close, or on your slowest days. When something fails mid-service, we prioritize it. And because rooftop and mechanical-room work happens out of sight, we document what we do with photos so you have a clear record of exactly what was serviced and why.
Honest Scoping, Fair Quotes
We give free replacement estimates and scope work honestly, if a unit can be repaired, we’ll tell you; if it’s failing and throwing good money after bad, we’ll tell you that too. Modern Air is licensed (CSLB #935704), family-run, and built on doing the work right the first time.
Call or text (408) 497-0444 to talk through your restaurant’s HVAC, make-up air, or refrigeration needs. Modern Air will send an experienced technician to assess your space and quote it upfront.

Commercial HVAC Questions
Why does my kitchen feel hot and the back door keep slamming?
That’s almost always a make-up air problem. When the exhaust hood pulls more air than the building can replace, the kitchen goes negative and air gets sucked in through doors and gaps. Modern Air balances make-up air to the hood’s exhaust rate so your kitchen breathes correctly and the dining room stays comfortable.
Do you service kitchen exhaust hoods and refrigeration too?
Yes. We handle the full picture, rooftop units, make-up air, exhaust fans, walk-in and reach-in refrigeration, and dining-room comfort. Refrigeration is where our company started, so cooler and freezer work is a genuine strength.
Can you work around our service hours?
Yes. We schedule maintenance and most repairs before opening, after close, or on slow days so your kitchen keeps running. Emergency refrigeration and cooling failures go to the front of the line, and we do our best to get there the same day.
Do you offer maintenance plans for restaurants?
We do. Grease-laden kitchens are hard on equipment, so scheduled coil cleaning, belt and filter changes, and refrigeration checks prevent the breakdowns that cost you a dinner service. Ask about our commercial maintenance contracts.
What areas do you serve?
We’re based in Morgan Hill and cover restaurants throughout the South Bay and Santa Cruz region, including San Jose, Gilroy, Santa Clara, and surrounding communities.
