About Lake Mary HVAC
Lake Mary HVAC, operated by 407Local, handles residential air conditioning across Lake Mary, Heathrow and the rest of ZIP 32746 in Seminole County, Florida: repairs, replacements and changeouts, heat pumps, maintenance, ductwork and humidity problems. We publish the permit rules, the code minimums and the rebate prerequisite because a homeowner who knows them asks better questions, and better questions are cheaper for everyone.
What to expect from us
- We check which building department your address files with before quoting it. In this ZIP code that is a real question and it has two answers.
- We size replacements from a load calculation on your house, not from the tonnage on the old data plate.
- We measure before diagnosing, and tell you the reading.
- We quote parts, compressor and labour warranties as three separate terms, because that is what they are.
- We raise the Duke Home Energy Check before you sign, not after the rebate has already been lost.
- We hold final payment until the permit is closed at final inspection.
How Florida licenses air-conditioning contractors
Florida licenses air-conditioning contractors through the Construction Industry Licensing Board at DBPR under Chapter 489, Part I. A Class A certificate under s. 489.105(3)(f) is unlimited in scope. A Class B certificate under s. 489.105(3)(g) carries the same scope capped at 25 tons of cooling and 500,000 Btu of heating in any one system, which covers every residential job in this market. Class C is air-conditioning service only. A CAC prefix means state-certified and valid statewide; RAC means registered and limited to a local jurisdiction.
Section 489.119(5)(b), Florida Statutes, requires that the registration or certification number “shall appear in each offer of services, business proposal, bid, contract, or advertisement, regardless of medium.” If a written quote arrives without a licence number on it, that is not an oversight to shrug at.
