How we vet Duct Repair & Sealing pros in Brandon

Our 5-step screening for Duct Repair & Sealing contractors serving Brandon, FL. This is the bar a HVAC pro has to clear before we route any quote request to them in Brandon.

1. 1

   Verify the Florida CMC license at the state source

   Pull the contractor's Florida CMC number and verify it's active and qualifier-matched at the state licensing portal. Any pro routing quotes to Brandon (33508) must carry an active license; a lapsed or qualifier-mismatched license is the single most common red flag we filter at intake.

2. 2

   Pull a current Certificate of Insurance

   Ask for a COI naming you as Certificate Holder, with $1M general liability minimum. The COI must be emailed by the agent directly, not a photo of a card. We refresh COIs annually for every HVAC pro on our network serving Bloomingdale and Heather Lakes.

3. 3

   Read Google reviews, filter for the last 12 months

   4.5 stars with 50+ reviews is the floor we use. Filter for reviews mentioning Brandon or nearby Heather Lakes so you see the recent local pattern, not a 5-year-old reputation from elsewhere in the metro. Patterns of "didn't return calls" or "left job unfinished" across 3+ reviews predict the same outcome.

4. 4

   Confirm trade-specific certifications for Duct Repair & Sealing

   EPA Section 608 Universal for refrigerant, NATE Core for diagnostics. R-454B handling certifications are increasingly relevant as 2025 systems ship. A pro working Brandon routes who can't name their certifications by acronym usually doesn't carry them.

5. 5

   Verify permit-pull history in Brandon

   Every HVAC job over the local trigger threshold requires a permit. Hillsborough County County publishes residential permit pulls in its open-data portal; cross-reference the contractor against pulls near Westfield Brandon mall. A pro with zero permits pulled in the 33509 corridor over the last 90 days is likely skipping them, which costs you on resale and insurance claims.
