Ductwork & Air Quality Systems in Miami: Cost, Companies and What They Disclose

Short answerThe short answer

Section 1Start with these three

Three full sheet excerpts to read first. Everyone else in this report follows in the table and the list below.

Section 2What to compare before you call

Ratings tell you whether past customers were happy. These six details tell you what you're agreeing to. Under each one is how many of the 122 companies in this report told us.

Section 3Comparison table

All 122 companies, listed alphabetically; the order is not a ranking. A dashed Not provided cell means the business hasn't told us and we couldn't confirm it from a public record. Not offered means the business told us it doesn't offer it.

Scroll the table sideways to see every column. The business name stays in view.

Section 6Questions to ask before you sign

Each question matches a field on our sheets. If a sheet says Not provided, this is where to ask.

1. Ducts, air quality or both?Have the answer ready before you ask for quotes; it changes the price.
2. Size of the home?Have the answer ready before you ask for quotes; it changes the price.
3. Any allergy, mold or humidity concerns?Have the answer ready before you ask for quotes; it changes the price.
4. What exactly is in the price?Get a line-by-line list: permits, materials, equipment, disposal and cleanup.
5. How much is the deposit, and what are the payment stages?Each payment should be tied to finished work you can see.
6. How do you price changes after I sign?Fixed written price per change, or cost plus a markup? What is the markup?
7. Which warranty covers what, and for how long?Ask for the warranty document itself, and whether it transfers if you sell the house.
8. Who does the work?Which parts are done by your own crew and which by subcontractors, and are the subcontractors licensed?
9. Can I see your license and a current insurance certificate?Check the license yourself on the state's license lookup, and ask the insurer to send the certificate.
10. What happens if I cancel?Before permits, after permits and after work starts: what do you keep, and what do you refund?
11. When could you start, and what delays the finish?Get the start date in writing, and ask how weather and inspections are handled.
