Who you are calling

About Loretto Cold Service

One product line, one neighbourhood, and no relationship with the manufacturer. Here is exactly what that means before you book anything.

One van, one trade, one part of town

Independent, and specific about it

The affiliation statement is printed in full in the footer of every page on this site, because it is the most important thing to be clear about. There is a manufacturer-run service network and this is not it. We are a separate business that has chosen to work on one manufacturer's refrigeration, which is a different thing entirely and gives you a different set of trade-offs.

What you give up is a factory relationship. What you get is that the person who answers the phone is the person who will be standing in your kitchen, and that the job is not being routed through a call centre to whoever happens to be nearest.

Why one product line

Sub-Zero makes refrigeration and only refrigeration: built-in refrigerators and freezers, integrated columns, undercounter units, refrigerator and freezer drawers, wine storage and ice makers. There are no ovens, no cooktops and no dishwashers in the range, which means one line of products is a complete and coherent thing to specialise in rather than a fragment of a catalogue.

Working on the same sealed systems, the same evaporator fans and the same control boards every day has a practical effect that is hard to overstate: the second and third time you see a fault, you recognise it. A shop covering eleven brands across cooking, laundry and refrigeration is meeting most faults for the first time.

The boundary runs further out than most people expect, so here it is in plain words. Loretto Cold Service is a refrigeration shop. It is not a heating and air-conditioning company: no furnace, heat pump, air handler, thermostat or duct run is diagnosed, repaired or installed here, and no quote is given on one. If the house is too warm or too cold and the kitchen cabinet is holding its temperature, the trade you want is not this one, and the honest thing to do is say so on the phone.

Why Mandarin

Mandarin is compact. From Beauclerc at the north end to Julington Creek at the county line is a short drive, and nothing in 32223, 32257, 32258 is far from anything else. That is not a marketing preference, it is what makes the model work: a return visit with an ordered part is a short trip rather than half a day, so parts do not sit for a week waiting for a route to make sense.

It also means the local conditions are consistent enough to know well. The housing runs largely to 1970s through 1990s subdivisions with older riverfront homes along Mandarin Road, nearly every one of those kitchens has been remodelled at least once so the appliance is newer than the opening it sits in, and the tree canopy that makes the neighbourhood pleasant is what packs a condenser. Those three facts explain most of what we are called about.

What we claim, and what we do not

EPA Section 608 certified technicians
Federal certification to recover, evacuate and charge sealed refrigeration systems. Required by law for anyone opening a sealed system, and genuinely held here.
Independent shop, no dispatch fee
You speak to the person who will be standing in your kitchen, not a call centre routing the job to whoever is nearest.
Sub-Zero built-in work only
Every day is spent on the same sealed systems, the same evaporator fans and the same control boards, in one product line.

EPA Section 608 is the only certification named anywhere on this site, and it is a real federal credential for handling refrigerant that is genuinely held here. We never describe this company as factory trained, certified or authorized by the manufacturer, because it is none of those things.

Customer reviews are published on this site, and the rules around them are the same ones. They appear with a first name and a last initial, which is all anyone agreed to. The average printed beside them is the plain arithmetic mean of that set and nothing else, so it can be checked against the entries it summarises. The four-star and three-star ones are left in, because a page of nothing but fives tells a reader less than one honest complaint about a part that took three weeks. They are all on the reviews page.

Reaching us

We work Monday to Saturday out of Mandarin, Jacksonville, FL, with no storefront and no counter — this is a mobile operation and publishing an address we do not staff would be a misrepresentation. The contact page has the hours, the area and what is useful to have ready when you call. Calls left outside 8:00am – 6:00pm on a weekday are answered the next working morning.

Questions we are asked

What people ask before they book

Are you part of the Sub-Zero service network?
No. Independent service. Not affiliated with Sub-Zero. There is a manufacturer-run network and this is not it. The brand is named here only to say which appliances are worked on, which is the whole reason the full statement sits in the footer of every page.
Who actually turns up?
The person you spoke to on the phone. There is no call centre routing the job to whoever is nearest, which is why the questions asked when you call are specific: they decide what goes on the van before it leaves.
Why only one manufacturer?
Because every day is spent on the same sealed systems, the same evaporator fans and the same control boards. Working Sub-Zero refrigeration and nothing else since 2014 is what makes the second and third example of a fault familiar rather than new.
Are the reviews on this site real, and how is the average worked out?
They are published with a first name and a last initial, which is as much as anyone agreed to. The 4.6 is the plain arithmetic mean of all 64 of them, recomputed whenever the pool changes, and the three-star entries are left in.
