About
RealReviews profileSub Zero has a current Key West office at 805 Peacock Plaza and 305-294-9243 on its website. Florida's Division of Corporations lists SUB-ZERO, INC., document L49404, active at the same principal address with a 2026 annual report. The site advertises residential AC service, maintenance, replacement, new construction, apartments and mini-splits, plus commercial HVAC and refrigeration for restaurants, bars, hotels, offices, retail, medical offices, builders and apartments. Named equipment includes air conditioners, chillers, ice machines, commercial refrigerators and freezers, heat pumps, walk-ins, cases, prep tables and remote condensers; the service page explicitly says the company does not work on window units. The site also says Sub Zero is part of the Rocket Cooling family. This relationship must not blur credentials: DBPR ties displayed license CAC1819491 to Daniel O. Peregrin doing business as ROCKET COOLING LLC in LaBelle, not directly to SUB-ZERO, INC. RealReviews did not independently resolve displayed CMC1251393. Require the quote and permit to name the contracting entity, qualifier and license. No individual review bodies were inspected.
Sub Zero: what to know
RealReviews editorial research · checked 2026-07-26Sub Zero clears the fifth-profile identity gate because its current site, Sunbiz record, phone and 805 Peacock Plaza office align, and Sub Zero and Rocket Cooling now explicitly describe the Key West relationship. It also publishes the most detailed commercial-refrigeration equipment scope in this five-company set and plainly excludes window units. The license presentation needs unusually careful handling: CAC1819491 is authority-verified to Daniel O. Peregrin and ROCKET COOLING LLC at a LaBelle address, not independently to SUB-ZERO, INC.; CMC1251393 was not conclusively resolved in the inspected authority sources. The contract and permit must name the actual entity, qualifier and license.
Strongest fit
- Restaurants, bars, hotels, offices, retail, medical offices, apartments and builders comparing commercial HVAC or refrigeration
- Residential central or ductless service, maintenance, replacement and new-construction requests
- Customers who can verify the Sub Zero and Rocket contracting relationship on the actual quote
Verify before booking Sub Zero
- Sub Zero explicitly says it does not work on window units
- Do not state that SUB-ZERO, INC. holds CAC1819491; the captured DBPR record belongs to ROCKET COOLING LLC and Daniel O. Peregrin
- The displayed CMC1251393 was not independently resolved in the captured authority evidence
- Emergency, technician, EPA, warranty and reputation claims need current job-level evidence
The current Key West identity is resolved
The current Sub Zero site publishes 805 Peacock Plaza, Key West, 305-294-9243 and email addresses on the rocketcooling.com domain. Sunbiz lists SUB-ZERO, INC., L49404, active at 805 Peacock Plaza with a 2026 annual report. The selected RealReviews row matches that address, phone and domain. A second stored row uses the same phone with a stale site.subzero-keywest.com domain and a former 6003 Peninsular Avenue address; it is held unchanged and is not treated as a separate recommended company.
This profile does not merge or erase the old row. It selects the current, stronger identity surface and protects the peer until a separate canonical action is approved. A proposal should identify whether SUB-ZERO, INC., ROCKET COOLING LLC or another disclosed affiliate signs, bills, carries insurance and applies for the permit. A current office and shared brand do not make every legal entity interchangeable.
Sub Zero and Rocket Cooling acknowledge the relationship
Sub Zero says it is proudly part of the Rocket Cooling family and describes the arrangement as adding support and resources while keeping the Keys team. Rocket Cooling's own service-area page says it serves Key West through Sub Zero, a Rocket Cooling company. Those reciprocal first-party statements are stronger than inferring an acquisition or affiliation from a shared email domain alone.
They do not disclose every legal term, ownership percentage, assumed liability, warranty transition, customer-data relationship or contracting rule. Ask which entity owns the estimate, deposit, warranty and service obligation; which insurance policy covers the crew; which license is used; and where complaints or warranty notices go. If a legacy Sub Zero warranty exists, confirm whether Sub-Zero, Rocket or the manufacturer administers it. The relationship is real enough to disclose and important enough not to oversimplify.
The license display cannot be assigned to the wrong corporation
Sub Zero's footer displays CAC1819491 and CMC1251393. DBPR identifies CAC1819491 as current and active under Daniel O. Peregrin doing business as ROCKET COOLING LLC, with a LaBelle main and license address. Monroe County's dated active-contractor report likewise lists ROCKET COOLING LLC, Peregrin, MC ID 17270 and CAC1819491. Neither inspected authority source names SUB-ZERO, INC. as the holder. The captured research did not conclusively resolve CMC1251393.
Accordingly, RealReviews can report the display and the current Rocket relationship but cannot say Sub-Zero, Inc. independently holds those licenses. Before regulated work, require the proposal and permit to name the contracting entity, qualifier and exact license, then verify that record directly. If Rocket contracts and Sub Zero markets or dispatches, write that. If Sub-Zero contracts under a documented qualifying relationship, provide the authority record. Precision here is more useful than a generic licensed badge.
Commercial refrigeration is the clearest differentiator
Sub Zero names restaurant and bar equipment more precisely than the other profiles: walk-in freezers and coolers, deli and meat cases, refrigerated display cases, sandwich prep tables and remote condensers, plus ice machines, chillers, commercial refrigerators and freezers. It also names hotels, offices, retail, medical offices, commercial home builders and apartments as commercial markets. Those first-party facts make Sub Zero a logical call for a detailed commercial asset shortlist.
Send manufacturer, model, serial, refrigerant, asset location, normal and current temperature, alarm or code, icing, sound, water, drain, condenser configuration, doors and gaskets, last service, product exposure, sanitation limits, operating hours, roof or kitchen access and deadline. Ask whether Sub Zero or Rocket accepts the exact manufacturer and warranty status. The proposal should separate diagnosis, leak location, repair, refrigerant, water and drain, controls, cleaning, return visit, after-hours, temporary measure and temperature acceptance test.
Window units are a documented poor fit
The services page says plainly that Sub Zero does not work on window units. That is valuable negative evidence. A Key West resident with a window shaker should not submit the job simply because the profile says HVAC. Route the request to an appliance, replacement or other provider that has explicitly accepted the equipment. Do not pressure Sub Zero to dispatch to a published exclusion or count that refusal as poor service.
The same principle applies to other asset classes. The site names air conditioners, chillers, ice machines, commercial refrigerators and freezers, heat pumps and several brands, but a named category is not a promise for every model, obsolete refrigerant, factory warranty, water-side chiller or proprietary control. Confirm exact acceptance, parts, tools, manufacturer authorization and expected diagnostic boundary before booking. Clear poor-fit routing improves conversion and saves both sides a failed service call.
Residential replacements still need evidence, not an age slogan
Sub Zero's site says a system more than ten years old and needing substantial repairs may be a replacement candidate. Age and repair cost are relevant but not a diagnosis. Ask for the failed condition, repair total, parts availability, refrigerant and known system or duct defects. Then compare replacement with matched indoor and outdoor models, load or sizing basis, capacity, efficiency, airflow, ducts or line sets, filter, controls, condensate, electrical, support, elevation, tie-down, disposal, permit, commissioning, registration and labor warranty.
ENERGY STAR warns that oversizing can cause short cycling, discomfort and shorter life; it calls for actual property characteristics, airflow, correct refrigerant charge and duct evaluation. The City checklist asks for make, model, tonnage, location, setbacks, elevation, roof conditions, new-duct layout, engineering for supports, AHRI certificates, manufacturer instructions, product approvals and a mini-split energy form. Ask the actual contracting entity to own these deliverables in writing.
EPA and technician claims require assigned-person evidence
Sub Zero says its technicians are trained, certified and EPA certified, and lists several refrigerants. Those are company claims. EPA says technicians who maintain, service, repair or dispose of covered stationary equipment in a way that could release regulated refrigerant must hold the applicable Section 608 certification. Ask for the assigned technician's card type when the circuit may be opened; do not assume every employee or office worker holds the same certification.
For refrigerant work, request the refrigerant type, why the charge is believed wrong, how a leak is located, what repair is included, evacuation and charging method, quantity, recovery, and post-repair operating test. Large commercial appliances can carry additional leak and record duties based on charge and refrigerant. Let the technician identify the applicable rule for the actual asset. The site language supports asking the question; it does not replace the individual record.
Emergency and warranty work need current terms
The contact page tells customers to call the same Key West number for weekend emergency service, while Rocket's broader site advertises 24/7 service and other response claims. The inspected Sub Zero pages do not create a complete Key West service-level agreement. Ask whether a person is available now, whether the commitment is callback, arrival or restoration, which entity dispatches, what premium and minimum apply, what geography is covered, and what happens when parts or a specialty technician are unavailable.
The services page also advertises startup and warranty work. Ask whether the company is authorized for the exact manufacturer and claim, which entity files it, what parts, labor, shipping, refrigerant, diagnosis and return visits are covered, and whether prior installation or maintenance records are required. Keep manufacturer warranty, installer labor warranty and service-plan promises separate. A footer logo or brand list does not prove current factory authorization for every model.
Review limits, quote normalization and corrections
The selected Google identity surface reports an outside 4.7 average from 146 ratings at the current address. RealReviews did not import the individual reviews, distinguish work performed before and after the Rocket relationship, inspect job types, or derive themes. The official site makes broad statements about reputation, dependability, quality and experience. This profile does not convert either source into a RealReviews recommendation or a claim about recurring customer outcomes.
Compare Sub Zero on exact entity, accepted asset, diagnosis, dispatch, part, labor, refrigerant, water or drain work, electrical, controls, permit, tax, warranty, retest and no-fix remedy. For replacement, add sizing, matched equipment, airflow, support, commissioning and registration. For commercial work, add product protection, sanitation, operating window and temperature acceptance. Sub Zero or Rocket may submit current relationship documents, licenses, insurance, warranty terms, technician evidence, equipment limitations or corrections. Updates must preserve the legal and credential boundary unless authority evidence resolves it.
