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 51% 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?
1,984 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 for each lead?
Owner name, property address, parcel number, permit year, structure type, and (where available) mailing address. Emailed plans get each list as a PDF and a spreadsheet; on the app, export unlocked leads as a spreadsheet or PDF, or print a walk sheet.
Can I work multiple trades from one account?
Yes — every plan covers roofing, HVAC, and solar. On an emailed plan you pick the trades for your list; on the app they are separate tabs in the same tool.
