Common Questions from HVAC Contractors
Can I present multiple equipment options?
Yes. Create separate services within one estimate for each option — standard efficiency, high efficiency, and premium. Clients see the price difference and choose what fits their budget.
How do I handle seasonal pricing changes?
Update your templates when supplier pricing changes. Your saved templates make it easy to adjust equipment costs across all your standard estimates.
Can I create maintenance agreement estimates?
Yes. Build an estimate for the maintenance plan, then convert it to a recurring invoice that bills monthly or quarterly.
