HVAC Change Order Template: Explain It to the Homeowner

HVAC change order template for the homeowner

Install-day surprises happen: a rotted platform, an undersized gas line, a panel that can’t carry the new load. How you explain the change decides whether the homeowner trusts the rest of the job. This prompt writes a clear change order explanation with photos referenced, the price from your book and real options.

What to get right

Show, then explain. Reference a photo for each item. Homeowners believe what they can see.
Give options. Do it now, do it later, or an alternative, each with a price and what happens if they wait.
Say the time impact. If it adds a day or needs another inspection, say so up front.
Nothing proceeds without a signature. Written approval before any extra work, every time.

Questions shops ask

What should an HVAC change order include?

The original scope, what changed and why, the price, the time impact, the options and a place for the homeowner’s signature. Photos make it much easier to approve.

Can we do the extra work and bill it later?

Don’t. Work done without written approval is the fastest route to a payment dispute. Get the signature first.

How do I avoid change orders in the first place?

A thorough pre-install walkthrough catches many of them: the platform, venting, gas line, electrical capacity and duct condition.
