Don't sweat commercial AC repair at your restaurant. Find helpful maintenance and troubleshooting tips for this restaurant infrastructure in our guide.
It’s a sweltering Southern summer day, and customers are coming to your restaurants in droves for cold drinks and a chance to escape the heat.
But there’s a big problem: the sweat on the brows of your customers doesn’t seem to dry. The kitchen is even stuffier than usual. And it’s looking like ice is starting to melt as soon as it drops from the machine.
A comfortable environment is critical for restaurants. So if your customers and staff aren’t at ease with the ambient temperature, you could lose valuable business—and maybe even employees.
Commercial air conditioning (AC) systems maintain low temperatures throughout interior spaces to keep people cool. So what do you do when your AC won’t work when you need it the most? Don’t sweat it—consider this an entry-level guide to understanding this vital part of restaurant infrastructure.
Commercial AC is the “AC” within the HVAC acronym. Where the Heating system increases indoor temperature and the Ventilation system removes polluted air and replaces it with fresh air, Air Conditioning systems decrease indoor temperatures.

The two common commercial AC systems within restaurants are:
Split, a type of HVAC system that has both exterior and interior components. In split HVAC systems, the compressor and condenser are outside the building, usually on the roof. Cooled air is then carried through ducts into different interior areas and dispersed through vents.
Multi-split, an HVAC system that doesn’t require ductwork. In multi-split systems, up to five different air outlets can be linked to the compressor through refrigerant lines. Cool air is then available in the areas where air outlets are present.
Unfortunately, keeping restaurant temperatures low can come at a high R&M price.
At 86 Repairs, we collect and document data about HVAC repairs and not individual needs within Heating, Ventilation, and Air Conditioning since one issue within that infrastructure can affect its entire ecosystem.

In 2021, 12.4% of repairs for our customers were related to HVAC issues. Because working HVAC is necessary for restaurants to open their doors, it may send a chill down your spine to learn that it’s one of the most expensive pieces of infrastructure to fix:
No need to lose your cool over the numbers. With preventative maintenance and troubleshooting, you and your team can continue going with the (air) flow and potentially avoid extensive downtime.
Considering the expense associated with HVAC repairs, it’s in the best interest of your business to avoid emergencies as much as possible. We recommend scheduling preventative maintenance from a professional HVAC technician who can clear furnaces, check burners and carbon monoxide levels, and look for leaks throughout the system.
Between those vendor visits, a maintenance schedule will help you and your team to get proactive in R&M management. Here’s what we suggest:
When filters are clogged in an HVAC system, air can’t flow properly—defeating the purpose of the infrastructure. Depending on the type of HVAC system installed at your restaurant, filters can be found around different intake points, like the kitchen, dining room, or even the back office. Don’t forget about your makeup air unit on the roof, too.
When seasons change, your thermostats should, too. Most restaurants don’t think to automatically program the thermostat to change from heating to cooling (or the other way around).
So, if your indoor temperature seems too hot when the AC is running, double-check the thermostat is on the correct setting.
If your AC doesn’t seem like it’s cooling your spaces and the thermostat is correctly programmed, you could have an issue with the HVAC’s rooftop package unit. You’ll want to check the unit’s condenser coils—they might have buildup from airborne contaminants, like dirt or plant material.
Cold weather can also be a factor in underperforming condenser coils. So if they’re frozen, turn your HVAC system off overnight and allow them to defrost.
Don’t lose your cool when your AC seems to be down. Try these troubleshooting tips before you contact an HVAC professional.
Room not getting to temp? Make sure you didn’t set the thermostat at an extremely low temperature. No matter how low you set that number, your system will always cool at the same rate. So, when you’re trying to get a space to cool down, change the thermostat to a reasonable temperature first to avoid freezing or overheating coils.
Once you’ve confirmed the thermostat is at a reasonable number,
If you can’t even check the thermostat settings because it’s blank,
When these troubleshooting steps don’t get your spaces to start cooling, you’ll need to call a technician.
For folks who aren’t trained in specialized repair services, it’s incredibly difficult to determine the exact source of a leak. So before you call a vendor in to take a look, know which vendor you actually need to call!
If you’re certain your AC system—and the HVAC system at large—needs to be seen by a specialist, check your warranty status before making any call for dispatch. This is best practice for every piece of equipment and infrastructure in your kitchens; after all, why would you want to pay out of pocket for a repair if the unit is still guaranteed to perform?
Was your restaurant building built within the last year? If so, check for warranty status with your general contractor first. It’s common for them to cover repairs within the first year the building was constructed. For further guidance on warranty coverage, go directly to the manufacturer of your HVAC system.
The various components of an HVAC system could be covered by different warranties, so make sure you and your team are crystal clear on what’s covered and for how long before requesting service.
Repairs and maintenance can finally feel like a breeze. With a preventative maintenance schedule, routine maintenance, and smart troubleshooting, a broken AC system doesn’t have to ice your business out of profits.
