Special Projects & Retrofit FAQs
What is a retrofit in HVAC or plumbing?
A retrofit upgrades part of your mechanical system—like replacing outdated components or adding new controls—without doing a full system replacement.
How do I know if I need a retrofit?
If your system is unreliable, inefficient, or no longer code-compliant, a retrofit may be the right solution. We’ll inspect and advise.
Can I keep operating during a retrofit?
Yes. We build project timelines that minimize downtime and disruption to your operations.
Do you handle permitting and inspections?
Yes. We manage all necessary approvals and ensure compliance with local and state regulations.
Will this impact my building automation system?
Only for the better. We ensure every upgrade is compatible or help upgrade your BAS as part of the retrofit.
