BEFORE YOU BOOK

What do you get from a diagnostic visit?

The purpose is to investigate the reported problem and explain the next step. A diagnosis is not a promise that every repair can be completed during that visit. Parts availability, access and the condition of the equipment may affect what happens next.

Scope, price and approval

The website diagnostic offer is $67 instead of the regular $95. It is an inspection and fault-finding visit, not a prepaid repair or a full system replacement quote. Repair work needs a separate scope and your approval.

COST & NEXT STEPS

HVAC Diagnostics questions

Does the diagnostic fee include parts and repairs?

The website offer is $67 for the diagnostic visit (regularly $95), not for the complete repair. The technician investigates the fault, explains the findings and quotes any proposed repair separately. Confirm the visit scope and applicable terms before dispatch.

What information should I expect after an inspection?

Ask what was observed or measured, what fault those findings support, and which next steps are recommended. A useful explanation separates the confirmed fault from possible additional issues and identifies any further testing or parts needed.

Is diagnostics the same as maintenance or an installation quote?

No. Diagnostics investigates a reported fault. Maintenance is planned service for the equipment, while an installation assessment considers replacement needs and project scope. Tell the dispatcher which outcome you need so the visit and price are confirmed correctly.
