AC Repair in Key West: What to Check Before You Approve the Work

First, rule out the simple problems

You do not need to dismantle equipment or work around live electrical components. There are, however, a few safe observations that can make the service call more useful:

Tell the contractor exactly what changed and when. “The indoor fan runs, the outdoor unit does not, and the breaker tripped twice” is more useful than “the AC is broken.”

If you smell burning, see damaged wiring, hear violent mechanical noise, or find water near electrical equipment, shut the system off if it is safe to do so and wait for a technician.

• Check that the thermostat is set to cooling and that its displayed temperature makes sense.
• Look for a tripped breaker once. If it trips again, leave it off and call a professional; repeatedly resetting it can hide a fault.
• Check whether the return-air filter is visibly clogged.
• Note whether the indoor fan runs, whether the outdoor unit runs, and whether either unit makes an unfamiliar sound.
• Look for water around the indoor equipment or drain line.
• Write down the model and serial number from the equipment label if it is accessible without opening a panel.

Key West makes the maintenance details matter

Key West’s climate is not a throwaway sentence for a location page. National Weather Service normals for 1991–2020 show an annual average temperature of **78.9°F**. The local office also reports that roughly **65% of annual rainfall falls from June through October**. Cooling equipment works in a warm, wet environment for much of the year.

That makes moisture management and airflow practical concerns. A maintenance visit should be more specific than “checked unit.”

The federal ENERGY STAR maintenance checklist includes:

You do not need every company to use identical wording. You do want to know what its advertised tune-up actually includes. Ask for the checklist before the appointment and the findings afterward.

• thermostat operation;
• electrical connections, voltage, and motor current;
• condensate-drain inspection;
• controls and startup/shutdown operation;
• evaporator and condenser coils;
• refrigerant level;
• blower components and airflow; and
• filter inspection or replacement.

Ask for the diagnosis, not just the recommended purchase

A written diagnosis can be short. It should still identify what the technician found.

For example:

> “Outdoor fan capacitor tested outside its rated range. Replace capacitor and retest system operation.”

That is more useful than:

> “System old. Recommend replacement.”

For a major recommendation, ask:

Equipment age matters, but age alone is not a diagnosis. Conversely, repeatedly repairing an unreliable system can be poor value. The goal is not “always repair” or “always replace”; it is a decision with visible assumptions.

• What failed?
• What was measured or observed?
• Is the failed part available?
• What would the repair cost?
• What other known condition makes replacement the better option?
• Is the quoted replacement the only appropriate capacity and equipment type, or one of several choices?
• Will the proposal include permitting, disposal, startup testing, and warranty registration?

A refrigerant “top-off” is not the same as a leak repair

If refrigerant is part of the diagnosis, ask the technician to explain:

EPA advises homeowners to ask technicians to locate and repair leaks rather than repeatedly topping off a leaking system. EPA also notes that the refrigerant type is normally listed on the equipment nameplate and that Section 608 certification is required for technicians performing covered refrigerant service.

If you have an older R-22 system, do not accept a vague promise that a different refrigerant can simply be dropped in. EPA says there are no true “drop-in” replacements for HCFC-22 without considering system components and performance.

• the refrigerant type;
• why the charge is believed to be low;
• whether a leak was located;
• whether the quote includes repairing the leak;
• how the system will be tested after the work; and
• whether the technician holds the applicable EPA Section 608 certification.

When a Key West mechanical permit enters the conversation

The City of Key West says mechanical permits provide plan review and inspections for code, zoning, safety, and setback compliance. The City also says mechanical permits are issued in the name of the person performing the work and may be obtained only by licensed contractors or qualifying owner-builders.

That does not mean every diagnostic visit or minor repair needs a permit. It means you should not let a replacement proposal leave the subject blank.

For installation or significant mechanical work, ask:

Do not rely on a contractor profile—ours or anyone else’s—as the final word on a permit. Confirm the requirement with the City for the actual scope and address.

• Does this scope require a permit?
• Is the permit included in the price?
• Who applies for it?
• What inspections are required?
• Who is responsible for corrections?
• How will I know the permit is closed?

Verify the contractor, not merely the company name

Monroe County publishes an active-contractor list with fields for the company, city, qualifier, county identifier, license number, and dated credential records. Florida’s Department of Business and Professional Regulation also provides a license lookup.

Match all of these:

Why the careful match? Similar business names and old directory listings are common. A statement such as “licensed and insured” is only useful when it identifies the entity, credential, and date checked.

• the legal or DBA business name;
• the person shown as qualifier, where applicable;
• the license number;
• the address or service identity; and
• the current status and relevant dates.

Compare quotes on the same scope

The lowest total can be the best quote. It can also be a thinner quote.

For repairs, compare:

| Item | What to look for | |---|---| | Diagnosis | Failed condition and supporting test | | Parts | Part name or specification | | Labor | Included work and exclusions | | Service fee | Whether it is separate or credited | | Warranty | Part and labor terms | | Follow-up | What happens if the symptom returns |

For replacements, also compare:

| Item | What to look for | |---|---| | Capacity | How sizing was determined | | Efficiency | Rated efficiency and matched components | | Scope | Equipment, electrical, drain, pad/stand, duct changes, thermostat | | Permitting | Filing, fees, inspections, and closeout | | Removal | Old equipment and refrigerant handling | | Startup | Commissioning or measured performance checks | | Warranty | Manufacturer registration plus installer labor coverage |

A useful technique is to send each bidder the same questions. You will learn as much from the clarity of the answers as from the price.

How to use ratings without letting them make the decision for you

A public rating can help you build a shortlist. It cannot tell you whether the business correctly diagnosed your equipment today.

Look beyond the average:

RealReviews keeps third-party ratings labeled separately from reviews submitted directly to RealReviews. Counts can differ between sites or change after capture. We do not sell a better rating, and claiming a profile does not change its placement.

• Is the rating source named and linked?
• When was the count captured?
• Are recent reviews about the service you need?
• Do reviewers describe the work, or only leave a star?
• Are there repeated comments about diagnosis, scheduling, communication, cleanup, or callbacks?
• Does the company respond constructively when something goes wrong?

A practical call script

You can use this without sounding like you are cross-examining anyone:

> “My system is [brief symptom]. Before I approve work, can your technician give me the diagnosis and proposed scope in writing? If refrigerant is involved, I’d also like to know whether a leak was found. And if replacement comes up, please show whether permitting and inspections are included.”

For an estimate:

> “Please separate any service fee, repair, optional work, and replacement alternative. What warranty applies to the part and labor?”

Good contractors are used to informed questions. Clear expectations also reduce misunderstandings for the business.

RealReviews profiles should help you see where a public rating came from, when it was captured, what facts were independently checked, and what remains unverified. A quote request is an introduction—not an endorsement and not permission to skip your own checks.
