Not sure why your AC or heat pump isn't working right? We diagnose the actual cause before recommending any repair.
Overview

FAQ
Frequently asked questions
How do I know if I need HVAC diagnostics instead of just a repair?
If you already know exactly what's broken, we can often go straight to repair. If something feels off but you're not sure why, diagnostics comes first so any repair is based on the actual cause, not a guess.
Do you service residential and small business properties?
Yes — we handle HVAC diagnostics for homes and small commercial properties throughout Sarasota, Bradenton, Venice, Tampa, and Arcadia.
Do I get pricing before any work starts?
Yes. We complete the diagnostic, explain what we found, and give you clear pricing before any repair work begins.
What should I tell you when I reach out?
Your address, the type of system you have if known, and a description of what's happening — noises, temperature issues, or anything unusual — helps us prepare for the visit.
Will a permit be needed?
Permits aren't included unless specifically stated on your estimate — a standard diagnostic visit typically doesn't require one.
What if you find something else once the work starts?
Occasionally a diagnostic reveals a second issue we couldn't see beforehand. If that happens, we'll explain it and quote it separately before doing any additional work.
Important Notes
Permits are not included unless specifically stated on your estimate. Manufacturer warranty must be verified by equipment and manufacturer — we'll confirm what applies to your specific unit. Hidden conditions, code upgrades, electrical upgrades, drywall or paint repair, major ductwork, and additional materials discovered once a job is underway may be quoted separately before we proceed. SegtVision does not claim authorized dealer, certified dealer, or specific licensing status unless specifically approved in writing.
