Permit years on file

A 15-year-old A/C in Florida is living on borrowed time.

Florida heat runs air conditioners harder than anywhere in the country — 12 to 15 years is a full service life here. The median system on this list was last permitted 20 years ago, and 50% are 20+ years out. These homeowners are facing a replacement decision soon, whether they know it or not; a repair call, an efficiency pitch, or a replacement quote all land better when you arrive before the breakdown does.

Frequently asked

How many HVAC leads does FirstKnock have in Largo, FL?

2,023 residential properties in Largo, FL whose last mechanical/heat-air permit is 15+ years old, sourced from Pinellas County Property Appraiser (pcpao.gov) permit records covering all 21 city and county issuing agencies.

Why use permit records instead of buying a call list?

Mechanical permits are public government records with a date stamp. When we show a home with no A/C permit since 1997–2007, that's a documented system age — not a modeled guess from a data broker.

What do I get when I unlock a lead?

Owner name, property address, parcel number, permit year, structure type, and (where available) mailing address. Export to CSV or print contact sheets.

Can I work multiple trades from one account?

Yes — every plan includes all trades and all markets. Roofing, HVAC, and solar lists are separate tabs in the same tool.
