Frequently Asked Questions

What is an HVAC Second Opinion?

An HVAC second opinion is an independent assessment from a technician who has no vested interest in selling you a new system. It verifies if a recommended repair or replacement is truly necessary.

Why is Independent Documentation important?

Independent documentation provides an unbiased, technical record of your system's condition. This is essential for resolving disputes with installers, supporting insurance claims, or proving code compliance.

Can you help with contractor disputes?

Yes. Our Comprehensive Dispute Documentation service provides the detailed technical reports and photos needed to address subpar installations or incorrect service with your original contractor.

Do you perform the actual repairs?

While NBS HVAC is a full-service contractor, our Second Opinion and Documentation services are designed for clarity. If we identify an issue, you can choose to have us fix it or take our report back to your primary provider.
