Walk-In Coolers and Freezers
Large walk-in freezers and coolers for restaurants and shops — installation, maintenance and repair, including compressor replacement when a walk-in fails.
Commercial refrigeration is the core of what DNA Refrigeration Heating & Cooling does. Our customers are restaurants, cafés, liquor stores, food trucks and multi-location operators across Fort Collins — businesses that cannot trade when a walk-in cooler warms up or an ice machine stops. Call (970) 932-2324 any time, day or night. We are open 24 hours, 7 days a week.

Everything on this page comes from the work our customers describe in their own Google reviews. We do not list services we cannot evidence, and we do not invent brands, prices or guarantees.
The scope is exactly what our reviewers describe: walk-in freezers and coolers, reach-in coolers, ice machines, sandwich tables and cabinets, food-truck refrigeration, liquor-store coolers, café refrigeration, and heating and cooling installation and maintenance for shops. One customer has us looking after nine locations. Another runs a liquor store in the mountains and had a walk-in cooler compressor replaced the next day, over the holidays. A café customer calls us the best fridge repair in the business for a very busy café with a lot of refrigeration.
A walk-in cooler or freezer is the heart of a food business. When it warms up, stock is at risk, service stops, and every hour costs money. That is why the reviews keep coming back to the same words: quick response, knowledgeable, honest work. A large walk-in freezer and a few smaller freezers; a liquor-store walk-in cooler with a failed compressor; walk-in installations and maintenance across nine shops — these are the jobs we are known for, in our customers’ own words.
Refrigeration work also means knowing what not to promise. We do not publish prices for refrigeration work, because every walk-in, reach-in and ice machine is a different job — different size, different refrigerant, different fault. We do not name equipment brands we have not verified, and we do not offer warranties we have not documented. When you call, we talk about your equipment and what it is doing, and we go from there.
Refrigerant handling follows EPA Section 608 rules as a general industry requirement: refrigerant is recovered, handled and disposed of properly, and systems are checked for leaks rather than simply topped up. That is a statement about how refrigeration work is done in this industry, not a claim about a credential held by any individual.
HVAC work in Fort Collins is licensed by the City of Fort Collins, not the state — Colorado licenses only electricians and plumbers at state level. Fort Collins licenses HVAC contractors through the City — ask us for our licence details when you call.
Each item below is evidenced by a customer review. Nothing here is invented, and nothing is listed that our customers have not described.
Large walk-in freezers and coolers for restaurants and shops — installation, maintenance and repair, including compressor replacement when a walk-in fails.
Reach-in coolers for cafés, restaurants and liquor stores: the upright units a business opens a hundred times a day, serviced and repaired so they hold temperature.
Commercial ice machine maintenance, repair and installation — the machines a restaurant or café cannot serve drinks without. See our dedicated ice machine repair page.
Preventative maintenance and repairs on sandwich tables and cabinets, the refrigerated prep equipment that keeps a sandwich shop serving through a lunch rush.
Refrigeration equipment in food trucks, fixed, cleaned and adjusted so a mobile business can keep trading. One customer has had us work on their food truck for years.
Walk-in coolers for liquor stores and the heavy refrigeration load of a busy café — equipment that has to hold temperature through constant opening and long trading days.
Call (970) 932-2324 and tell us what the equipment is — walk-in, reach-in, ice machine, sandwich table, food-truck unit — and what it is doing. We are open 24 hours, 7 days a week.
We look at the equipment where it stands, check temperatures and operation, and find the fault rather than guessing at it.
We explain what failed and what the repair involves, and where the equipment is old or the repair is large, what replacement would involve.
We carry out the agreed repair or installation, then check that the equipment holds temperature and runs as it should.
For businesses with several units or several locations, we talk through a maintenance schedule so the next failure is caught on a planned visit, not during service.
Call (970) 932-2324 and tell us what the equipment is — walk-in, reach-in, ice machine, sandwich table, food-truck unit — and what it is doing. We are open 24 hours, 7 days a week.
When refrigeration fails, a business stops trading. These are the problems our customers call us about.
Ask a pro →A walk-in that will not hold temperature puts stock at risk. We find the fault — compressor, fan, controls, door seal or refrigerant — and repair it, as we did for a liquor-store walk-in cooler over the holidays.
A failed compressor is the most serious walk-in fault. One customer’s liquor-store compressor failed over the holidays and a new one was installed the next day.
An ice machine that stops, or makes too little ice, stops drink service. We maintain, repair and install commercial ice machines.
Prep equipment that will not stay cold slows a whole kitchen. We carry out preventative maintenance and repairs on sandwich tables and cabinets across multi-location accounts.
