The three systems in a restaurant
A restaurant in Panama City runs three different systems at once, and they are often treated as one. The Climatiza page on air conditioning and exhaust for restaurants separates them like this: kitchen exhaust, refrigeration and the dining room. Each one fails in its own way and costs something different when it stops.
| System | What happens if it fails | What to check | Main risk |
|---|---|---|---|
| Kitchen exhaust | The kitchen fills with smoke and heat and staff cannot work | Hood, filters, ducts and exhaust fan | Fire from built-up grease |
| Refrigeration (walk-in cooler, cold rooms) | Temperature drops without warning and stock is lost | Condenser, evaporator and operating temperature | Loss of product |
| Dining room air | The room gets hot and customers leave | Filters, coils, drains and ducts | Fewer customers |
According to Climatiza, the dining room is the most expensive failure and the least reported, because customers do not complain: they simply do not come back. That is the company’s own description on its website; no public figure measures it.
Kitchen exhaust: hood, filters and ducts
Every service sends grease-laden vapor into the exhaust system. According to the Climatiza website, part of it stays in the filters and the rest settles on the duct walls, where it cools and builds up in layers. Over the months, the inside of the duct stops being just an air passage. The restaurant competitiveness booklet from Seguros SURA Panamá puts it in one sentence: hoods, extraction filters and air ducts tend to collect oils, grease and food residue, mostly above griddles, fryers and industrial stoves, which makes fires easier to start and spread. The same booklet recommends constant maintenance and cleaning programs for those surfaces and calls it advisable to install fire-extinguishing systems for kitchens.
Before a fire, grease leaves everyday signs. Climatiza lists these on its kitchen duct and hood cleaning page:
- The hood pulls less air and the kitchen heats up.
- A grease smell reaches the dining room or the street.
- Grease marks or drips show around the hood.
- The exhaust fan gets noisier or vibrates.
- There is no record of when it was last cleaned.
- The insurer or the building manager asked for proof of cleaning.
How often to clean by cooking volume
The international reference is NFPA 96, on ventilation control and fire protection of commercial cooking operations. Climatiza uses it on its website to set inspection frequency by kitchen type. The table below reproduces that classification as the company publishes it.
| Type of operation | Inspection frequency |
|---|---|
| Systems serving solid fuel equipment (wood, charcoal) | Monthly |
| High-volume kitchens: continuous operation, grill, wok, fryers in heavy use | Quarterly |
| Moderate-volume kitchens | Every six months |
| Low-use or seasonal kitchens | Yearly |
According to Climatiza, these categories assume an off season, and in Panama City almost no commercial kitchen operates fewer than twelve months a year. In the company’s view, treating a kitchen that works every day as moderate volume is optimistic. That is Climatiza’s assessment, not a rule of the standard.
NFPA 96 is an international standard. At the time of writing, no published Panamanian rule setting a frequency for kitchen hoods was located, so the table works as a technical reference and not as a local legal requirement. The requirement in force for each venue is confirmed with the fire department and the insurer.
Refrigeration: walk-in coolers and cold rooms
A cold room that loses temperature gives no warning: product is lost and the bill arrives the next day, as Climatiza describes it. The sensitive part is the condenser. On its website the company cites a 2023 study in the International Journal of Air-Conditioning and Refrigeration that measured consumption increases of up to 20% in small-scale commercial refrigeration systems with a dirty heat exchanger. It adds that, according to the technical literature, each degree Celsius of extra condensing temperature raises compressor consumption by 2 to 4%.
Those figures are attributed to the Climatiza website; the original study could not be opened at the time of writing, so they are best read as an order of magnitude. Climate matters too: the site explains that in Panama refrigeration equipment starts against a temperature difference that never drops, and that manual intervals assume a different climate. On the coast, the guide on salt air and air conditioning explains why coils deteriorate sooner.
The dining room: a hot room empties the place
Dining room air is handled by the same kind of equipment as an office or a shop: filters, coils, drains, ducts and diffusers. The preventive check of those points is what the Climatiza air conditioning maintenance service describes, covering performance, filtration, coils, drains, electrical components, refrigerant and ducts, with a written report for each visit. To see what an annual agreement can include, there is a separate guide on the air conditioning maintenance contract for businesses. For the air moving through dining room ducts, another covers air duct cleaning.
For groups with several venues, one calendar saves work. According to Climatiza, a group does not need several providers but an initial survey of all venues, which almost always shows they are not in the same condition, a single calendar with priorities by site, and a report per venue in common language so they can be compared.
What a proper cleaning should include
A clean duct and a dirty one look the same from the kitchen, so documentation is part of the service. This is the eight-step sequence Climatiza publishes for hood and duct cleaning, useful as a checklist when comparing proposals:
- Prior inspection of the whole system with a camera and a photo of the starting condition.
- Area protection so the whole kitchen does not need cleaning afterwards.
- Filters: removal, degreasing and replacement; any warped or perforated filter is reported.
- Hood: cleaning of interior surfaces, collection channels and plenum.
- Ducts: mechanical cleaning through existing access doors along the whole accessible length.
- Exhaust fan: cleaning of blades, housing and base.
- Verification with a second camera inspection and a photo of the final condition.
- Report with findings, before and after photos and recommendations.
When finished, according to the website, the restaurant receives a dated report with scope, before and after photos, a record of inspected and inaccessible sections, a recommended frequency and proof of work useful for the insurer. If the system lacks enough access doors, some sections cannot be cleaned or verified, and the report should say so.
Climatiza describes on its website air conditioning and exhaust for restaurants, with kitchen duct audits, cleaning, maintenance contracts and an asset survey for those who run several venues.
Frequently asked questions
How often should a restaurant hood and ducts be cleaned?
It depends on cooking volume: the NFPA 96 reference, as published by Climatiza, runs from monthly for solid fuel to yearly for low or seasonal use. High-volume kitchens fall in the quarterly category.
What is the risk if grease builds up in the ducts?
The main one is fire, because grease deposited in the duct can carry flames to the rest of the building. Seguros SURA Panamá warns that grease in hoods, filters and ducts makes fires easier to start and spread.
Can cleaning be done without closing the restaurant?
According to Climatiza, its scheduled work is done outside service hours and agreed during a prior visit.
What should the company deliver after the cleaning?
A report with date, scope and staff, before and after photos, the record of inaccessible sections and a recommended frequency. That proof is useful for the insurer or the building manager.
Why does restaurant equipment fail more often in Panama?
Because the kitchen works all year with high temperature and humidity and no off season, according to the Climatiza website. Manual maintenance intervals assume a different climate.
