Florida qualifies expert witnesses by knowledge, skill, experience, training, or education, and applies the Daubert standard, which tests whether an expert’s opinion rests on sufficient facts, reliable methods, and a sound application of those methods. A State Certified Class A contractor’s field experience qualifies them to opine on commercial HVAC and refrigeration contracting matters — provided the opinion stays within that expertise and is reliably reasoned.
An expert witness may be qualified by knowledge, skill, experience, training, or education — any of these, not only formal credentials. This is why a contractor with extensive field experience can qualify as an expert on matters within that experience: experience is an explicit basis for expertise.
A State Certified Class A Air Conditioning Contractor who has installed, serviced, and diagnosed commercial systems for a living is qualified, by experience, to opine on those contracting matters. The qualification is real and recognized.
Florida applies the Daubert standard to expert testimony, which asks whether the opinion is reliable: is it based on sufficient facts or data, is it the product of reliable principles and methods, and has the expert applied those principles and methods reliably to the facts of the case? It is a gatekeeping test for whether the testimony is admissible.
Daubert is not about whether the expert is credentialed enough in the abstract — it is about whether this opinion, on these facts, is reliably reached.
The first prong asks whether the opinion rests on enough evidence. An opinion built on a thorough investigation — the equipment examined, the records reviewed, the data analyzed — satisfies this; one built on assumption or a glance does not. This is why the evidentiary foundation matters so much.
An expert who has actually examined the evidence stands on solid ground here; one who has not is exposed.
The opinion must come from a sound method, applied properly. For a forensic HVAC analysis, that means reasoning from the evidence against recognized codes, manufacturer requirements, and trade standards — a transparent, repeatable approach, not an ipse dixit “because I say so.” The method has to be shown, which is part of why a defensible report lays out its reasoning.
An opinion a qualified peer could follow to the same conclusion, by the same method, is reliable in the way Daubert requires.
Qualification is matter-specific: an expert is qualified on the subjects their knowledge actually covers, not everything adjacent. A contractor expert opining on field workmanship is on firm ground; the same contractor opining on engineering design analysis is not, and a Daubert challenge would target exactly that overreach. See contractor vs engineer expert.
This is why we engage a Professional Engineer for engineering-judgment questions — it keeps each opinion within the expertise that qualifies it.
An expert who is genuinely qualified by experience, has examined sufficient evidence, reasons by a reliable and transparent method, stays within their expertise, and is honest about uncertainty is the expert who survives a Daubert challenge and cross-examination. The discipline that makes an opinion reliable is the same discipline that makes it admissible.
We approach every engagement that way — qualified by Class A field experience, reliable in method, and confined to our genuine expertise.

A gatekeeping test for the reliability of expert testimony, applied in Florida. It asks whether the opinion is based on sufficient facts or data, is the product of reliable principles and methods, and whether the expert applied those methods reliably to the facts of the case — determining whether the testimony is admissible.
It can, on matters within that experience. A contractor opinion built on a thorough investigation, reasoned from the evidence against recognized codes, manufacturer requirements, and trade standards by a transparent method, and confined to contracting expertise, meets the reliability the standard requires.
Yes — qualification is matter-specific, and a Daubert challenge targets exactly that overreach. A contractor opining on field workmanship is on firm ground, but the same contractor opining on engineering design analysis is not. Engaging a Professional Engineer for engineering questions keeps each opinion within its qualifying expertise.
