Sub Zero
HVAC Repair · Key West, FL
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 2026-08-07RealReviews consensus score 80/100, Moderate confidence. The packet documents recurring HVAC response, repair, pricing and follow-up themes across six source domains and nine inspected bodies. The strongest customer signal is speed paired with explanation. A June 2026 BestPros body says Kevin arrived promptly, checked the system thoroughly and discussed possibilities even though the cause of a temperature change was not found. Two April bodies describe Carlos as knowledgeable, polite and clear, with one saying he identified and fixed a thermostat problem during a Sunday heat event. A Birdeye/Google body says KT cleaned and fixed a mini-split drip quickly and was courteous, professional and fast. Yahoo's visible Yelp excerpts add coil cleaning, pressure checks, next-day maintenance, courteous installation help and replacement work. That is useful evidence of how customers describe service, but it is still a selected sample rather than a failure-rate study.
Strongest fit
- Key West homeowners comparing AC repair, maintenance, mini-split or replacement help
- Restaurants and property managers with commercial refrigeration, ice-machine or chiller needs
- Customers who want technicians to explain tests, possibilities and next steps
Verify before booking Sub Zero
- Ask which legal entity and license qualifier will sign the quote; the site presents Sub Zero within Rocket Cooling while DBPR names Rocket Cooling LLC
- Confirm emergency, weekend, diagnostic, refrigerant and after-hours charges in writing
- For replacement work, compare model, capacity, efficiency, startup, line-set, disposal and warranty terms
- Platform aggregates and visible samples differ; positive text does not establish a complete complaint rate
What customers repeatedly praise
The recent BestPros bodies focus on concrete service behavior. One says the technician arrived promptly and performed a thorough check while explaining what could and could not be ruled out. Another describes a quick response to a blank thermostat on a Sunday, a diagnosis of the cause and a fix. A third praises a new customer-service experience, clear explanations and quality work. The Birdeye body adds a fast mini-split drip repair, and Yahoo's excerpts mention prompt maintenance and courteous replacement support.
Across those accounts, the repeated theme is not simply a star number. Customers describe technicians who arrive, test, explain and either resolve the fault or make the next decision understandable. That does not guarantee same-day availability, a particular technician or a repair without a return visit; those terms belong in the work order.
Services and the Rocket Cooling licensing boundary
The official site lists consultation, installation, startup, repair, maintenance and warranty work for air conditioners, chillers, ice machines, commercial refrigeration, freezers and heat pumps, and says window units are excluded. The office address is 805 Peacock Plaza and the site displays CAC1819491 and CMC1251393 while identifying Sub Zero as part of Rocket Cooling.
DBPR's inspected record names Rocket Cooling LLC DBA and Daniel O. Peregrin for CAC1819491; it does not independently establish that SUB-ZERO, INC. holds that license or that CMC1251393 was verified in the same record. Sunbiz confirms the active Sub-Zero corporation and Peacock Plaza address. A careful quote should name the contracting entity, qualifier, license and warranty issuer rather than collapsing those records into one unsupported credential claim.
How to compare an HVAC or refrigeration proposal
For a repair, request the symptoms, tests performed, failed component, refrigerant or electrical assumptions, temporary-versus-permanent fix, dispatch charge, return-visit terms and expected operating check. For maintenance, ask whether coil cleaning, pressure checks, drain work, airflow measurements, electrical inspection and photos are included. The Yelp excerpts specifically mention coils and pressure, but a review is not a promised checklist for every appointment.
For an installation or commercial system, compare model and capacity, efficiency, line-set and condensate changes, controls, permits, startup readings, disposal, labor warranty and manufacturer registration. For restaurants, name the refrigeration or ice-machine equipment and the response window. Confirm weekend or emergency pricing before authorizing work, especially when a same-day response matters more than a lowest headline quote.
Why RealReviews does not publish a score yet
Nine visible bodies are enough for a Moderate positive-skew profile, but not for a defensible proprietary number. The sample comes from selected directory views and attributed excerpts; Yahoo shows a 4.0/11 Yelp snapshot while other surfaces show different totals, and the aggregate counts cannot be blended or treated as body-level evidence. We report the repeated themes and preserve the uncertainty.
The licensing relationship also matters. Sub Zero's public brand and Rocket Cooling's regulator record are related in the first-party material, but the exact entity signing a Key West job should be confirmed. Customers can make this profile more useful by submitting a dated first-hand account that names system type, response, diagnosis, price clarity and outcome. Until then, verify the current license, contracting entity, scope and total price yourself.
The contracting entity needs confirmation
The site presents Sub Zero within the Rocket Cooling family while DBPR names Rocket Cooling LLC. Ask which legal entity and qualifier will sign the quote and warranty.
Identity and brand presentation should match the contract.
Prompt response is a repeat strength
June 2026 and April bodies describe prompt arrival, thorough checks, knowledgeable technicians, clear explanations and a Sunday heat-event repair. Those accounts support observed responsiveness, not a universal guarantee.
Ask for the current emergency window.
A careful diagnosis is useful even without a fix
One body says Kevin checked the system thoroughly and discussed possibilities even though the temperature cause was not found. That is evidence about explanation and process, not proof that every fault will be solved on one visit.
Ask what the next diagnostic step costs.
Mini-split work needs its own scope
A Birdeye/Google body describes a mini-split drip cleaned and fixed quickly. Confirm condensate path, drain, cleaning, parts, warranty and whether the return visit is included for another system.
Do not apply a mini-split review to central replacement.
Replacement quotes need capacity details
For a replacement, compare model, capacity, efficiency, line-set, electrical interface, startup, disposal, permits, labor and warranty. A repair review cannot answer those installation questions.
Get the sizing basis in writing.
Maintenance details are concrete
Yahoo excerpts mention coil cleaning, pressure checks and next-day maintenance, along with courteous installation help. Ask which maintenance tasks and measurements appear on the invoice.
A maintenance claim should be auditable.
The evidence is Moderate and platform-mixed
Nine visible bodies across independent surfaces support a useful profile, while different platform samples and the contracting-entity boundary limit a proprietary score.
Positive narratives do not establish a complaint rate.
What to verify before booking
Confirm entity, license, diagnostic, refrigerant, emergency, weekend, after-hours, equipment, warranty, permits, startup and return-visit charges.
Save the written terms before dispatch.
Separate HVAC from electrical work
A replacement may require electrical, structural, duct or line-set work. Confirm who owns each task and how coordination or change orders are handled.
Scope boundaries prevent surprises.
What a future review should record
Record equipment, symptom, date, arrival, technician, diagnosis, repair, price, warranty and performance after the visit. Specific details help distinguish a one-off from a repeated pattern.
The system and outcome matter.
Who Sub Zero may fit
It may fit a customer who values quick response, clear explanations and documented maintenance or repair work. Compare alternatives when a particular manufacturer credential or fixed emergency promise is required.
The contract determines fit.
Keep the service file
Save model and serial numbers, estimates, permits, startup notes, invoices, photos and warranty contacts. Those records make a later callback easier to evaluate.
Documentation is part of service quality.
Use the exact question at handoff
Ask which entity signs, what the diagnostic includes, who pays for a return visit and what the warranty covers. Put those answers beside the appointment.
Specific questions beat a generic average.
Do not turn one success into a guarantee
The visible bodies describe useful experiences, but staffing, parts, weather and equipment can change the next result.
The profile communicates evidence with limits.
Separate the business from the exact job
The researched record for Sub Zero combines official identity and service information with dated independent accounts. Scope, crew, price and timing can change the result, so each conclusion keeps those conditions visible.
A business-level summary is useful orientation; the exact job determines fit.
Use positive and negative accounts responsibly
A favorable account shows what worked for one customer, while a critical account identifies a possible failure mode. Repetition and specificity matter more than one dramatic sentence.
RealReviews reports the overlap and names the gaps instead of turning one experience into a universal accusation or guarantee.
Total cost includes friction
Fees, travel, equipment days, permits, access, recurring service and correction effort can change value. Compare the complete job, not just the displayed rate.
Write assumptions down before deciding so alternatives are measured fairly.
Policies should be saved
Warranty, callback, claims, cancellation, permit, payment and change-order rules can change. Save the current written terms and any promise made during a call or estimate.
That record protects the customer and gives the provider a fair chance to respond.
Do not confuse popularity with fit
Aggregate ratings show that people chose the provider; they do not answer whether this reader needs emergency response, a particular license, commercial coverage or a branch-specific callback.
The narrative tradeoffs are what make a shortlist useful.
What stronger evidence would add
The best future account identifies the date, exact service, equipment or fixture, crew, scope, price, response and outcome. Generic praise adds less than one specific, attributable review.
Update the profile when new evidence materially answers a current uncertainty.
Keep the recommendation conditional
Choose Sub Zero when its documented strengths match the job and its watch items are manageable. Compare another option when one watch item is a hard requirement.
Verify current details immediately before committing because services, prices, crews and policies change.
A practical final check
Confirm current identity, scope, total price, timing, access, warranty or claims and the one uncertainty most likely to affect the job. Afterward, keep the invoice and document the result.
That loop turns a researched profile into a decision tool and gives future updates better evidence.
A fair negative account is specific
A useful negative account names the date, promised standard, observed problem and response. It avoids turning one disappointing job into a claim about every employee or project.
That standard preserves important warnings while keeping the profile fair and verifiable.
Use the exact question as the handoff
If the concern is warranty, ask for the callback owner. If it is payment, ask when invoices post and what receipts are provided. If it is a permit, ask who closes the inspection.
Specific questions are easier to answer, verify and improve.
Record what is current
Write down the date checked, exact category, license or branch and policy language. If the provider changes a service, crew, permit path or schedule, a dated record makes the next update understandable.
That discipline keeps a local profile useful without pretending it is a permanent contract.
Timing is part of the evidence
Emergency repair, planned installation, recurring service and commercial work have different constraints. Keep timing and purpose attached to the claim rather than averaging every job into one impression.
That context lets a reader plan a comparable service.
The exact scope controls the answer
Cleaning, duct treatment, leak repair, water-heater work and commercial service require different questions, materials and paperwork. Ask the provider to name the exact phase before comparing a quote.
A general service page cannot answer a project-specific risk.
Compare one written alternative
Use the same problem description and requested scope when comparing another provider. Compare license, diagnosis, equipment, warranty, callback, payment, permits and change-order terms.
A fair written comparison is more useful than another unstructured list of stars.
The complete decision includes documentation
Before authorizing service, save the diagnosis, scope, identity details, price, warranty and escalation path. Afterward, keep the invoice, photos and service notes.
That record protects the customer and gives future updates better evidence.
A quote should expose assumptions
Ask what the estimate assumes about access, parts, equipment, permits, labor, disposal, cleanup and a return visit. If one assumption changes, the provider should identify the resulting price or schedule change.
An explicit assumption is easier to compare than a low number with hidden conditions.
A service term is not a service result
A posted policy explains what the provider says it will do; a review body describes what happened in one observed job. Keep those evidence types separate and ask how the policy is applied in the exact situation.
That distinction protects the reader from treating marketing language as a guarantee.
Ask who owns the next step
For a callback, re-clean, warranty, permit or return visit, identify the person or channel responsible and the expected response time. A general office number is not the same as a documented escalation path.
Write that handoff beside the estimate before work starts.
Compare like-for-like scope
A clean, duct treatment, leak repair and installation can have different labor, materials and completion standards. Use the same room count, equipment, access and deadline with every provider.
Matching scope reveals meaningful differences instead of rewarding omitted work.
Dated evidence deserves dated language
Older accounts can identify a question without proving a current pattern. Recent accounts can show a present strength without promising the next result.
The profile keeps dates, source context and counterexamples visible so the reader can judge how much weight to give each account.
The reader should leave with a decision
After reading the profile, a customer should know who may fit, what to ask, which term could change the price and what evidence remains incomplete.
That is more useful than a long recap of ratings because it converts research into a concrete next step before the first call or booking, with the important assumptions still visible for this job.
The customer controls the comparison
Bring the same facts, photos, equipment details and deadline to every provider. Ask each one to state what is excluded and what would trigger a second visit.
That makes the final choice depend on evidence rather than sales momentum.
A narrow warning can still help
A dated complaint about a missed callback, access problem or billing term does not define the whole business. It does identify a question worth asking before money or time is committed.
Specific warnings are more fair and more useful than broad labels.
The final record should be reusable
Keep the estimate, terms, invoice, photos, license check and outcome together. If the work succeeds, that record helps a future review; if it fails, it supports a precise correction request.
Good documentation improves the next customer decision.
