Four hundred and sixty companies want this job. Nine questions narrow it to three.
The hardest part of replacing an air conditioner in Jacksonville isn't the equipment. It's that four hundred-plus companies, many of them owned by the same few investors, are all saying the same thing on the same billboards.
The market you’re shopping in
Roughly 460 HVAC companies work the Jacksonville area, about fifty of them with multiple locations, and a growing share of the familiar names belong to national franchises or private-equity roll-ups that buy local companies and keep the local name on the van. Advertising is heavy, sales targets are real, and the person at your kitchen table may be a commissioned closer rather than the person who’ll install the system. The crowding thins out fast past the city line; owners in Baker County and western Nassau have far fewer names to choose from and often hear the same three. None of that is automatically bad. It does mean the homeowner has to run the interview, because nobody else will.
Nine questions, and the answers that should worry you
| Ask | A good answer | A red flag |
|---|---|---|
| 1. Will you do a load calculation? | “Yes, room by room, and you get a copy.” | “We size by square footage” or “the old one was three tons, so three tons.” |
| 2. Who actually installs it? | Named employees, and the lead installer’s experience | “Our install partner” or a subcontractor you’ll meet on the day |
| 3. What’s your license number? | On the quote, and it matches the state lookup | Hesitation, or “we work under another company’s license” |
| 4. What’s included and what isn’t? | A written scope: permit, line set, drain, electrical, duct changes, start-up, haul-away | A price with a brand and a tonnage and nothing else |
| 5. How will you commission it? | Charge by measurement, airflow verified, static pressure read, thermostat set up | “We turn it on and make sure it’s cold.” |
| 6. What rebate applies and how? | The JEA tier numbers, the amount, and whether the cycle is open | “You’ll probably get a rebate” or a promised federal credit for a 2026 install |
| 7. What’s the warranty, in writing? | Manufacturer parts term, labor term, who registers it | “Lifetime” with no document, or warranty only if you buy their plan |
| 8. How long is this price good for? | Days or weeks | “Tonight only” |
| 9. Who answers at 2 a.m. in August? | A real dispatch, and the after-hours fee stated plainly | An answering service that “will have someone call back” |
The red flags in the quote itself
- No model efficiency numbers. SEER2, EER2 and HSPF2 should be written out. A brand and a tonnage is not a specification.
- “Package pricing” with tiers named Good, Better, Best and no scope difference between them except the equipment.
- A discount that expires when the salesperson leaves. Equipment prices don’t change by the hour.
- Financing as the headline. A monthly payment in large type and a total in small type is a sales technique, not a price.
- A free system inspection that ends in a replacement recommendation within the first ten minutes, before anyone opened the air handler.
- No mention of the ducts. In Arlington’s 1950s-60s block ranches and Mandarin’s 2000s two-stories alike, the ducts are half the job.
What to look at besides the quote
The license. Florida contractors carry a state license; the number belongs on the quote, the contract and the vehicle. Look it up on the DBPR site and read the status and any complaints. It takes two minutes.
The reviews, read sideways. Ignore the star average. Read the three-star reviews and the owner’s replies to the one-stars. How a company handles a problem tells you more than how it handles a happy customer.
Who owns the company. Ask directly. A locally owned company and a brand owned by an out-of-state fund can both do good work, but they answer to different people.
Whether they’ll tell you no. Ask what they’d do if the compressor were fine and only the capacitor had failed. The right answer is a capacitor.
How Cook’s answers the nine
We’d rather be measured by this list than by a billboard. Cook’s is family-owned, sells Lennox, and works out of 37 Fairmont Ln in Palm Coast, which means the honest answer to “where is your office” is sixty miles south, and the honest answer to “how do you cover Jacksonville” is route days and stocked trucks on I-95. Our technicians are employees; Jerry handles sales and Sean leads the technical side. Every quote has a load calculation, a written scope, the efficiency numbers and the JEA rebate line. Dispatch is staffed around the clock, and a 3 a.m. repair is priced like a 3 p.m. one. The license number appears on every document; if it isn’t on something you’ve received from us, ask. A replacement estimate costs nothing, and we will tell you when a repair is the better answer.
The three you should end up with
After the nine questions, most homeowners find that three companies gave complete answers and the rest didn’t. Compare those three on scope, not on price alone, and pick the one whose installer you’d want in your attic. That is the whole method. It works in a market of 460 as well as in a market of six.
Choosing a contractor: what people ask
Is a franchise or a national brand automatically worse?
No. Some run excellent local crews. The concern is a sales model built on quotas and same-day closing, which produces oversized systems and pressure. Ask the same nine questions of everyone and judge by the answers.
Should I get three quotes?
Two or three, yes, as long as each one includes a load calculation and a written scope. Three quotes that all guessed the size from square footage are one bad quote repeated.
Why does one quote come in at half the price?
Look for what’s missing: a permit, a new line set, duct modifications, a drain-line float switch, start-up and commissioning, or warranty registration. A very low quote is often a complete quote with the hard parts deleted.
How do I check a Florida contractor's license?
The Florida DBPR license search lets you look up any contractor by name or license number and shows the license status, type and any disciplinary history. The license number should appear on the quote and on the van.

Riverside bungalow or Beaches condo, a person takes the call at 3 a.m. and the rate stays where it was at noon.
