Short answer
Each of these does the part a customer genuinely cannot do alone: weigh the factors a technician weighs, compute an incentive exactly, or structure the quotes you were actually given. None of them invent a price, and none of them send anything anywhere: they run entirely in your browser with no network request and no stored data. Repair-or-replace weighs a system's age against its typical service life, what actually failed and whether this is the first unplanned repair, then tells you what a complete proposal needs to cover.
The rebate calculator works out the incentive side exactly, because published amounts are facts with a source and a date, unlike installed cost, which depends on access and what a contractor finds once a panel comes off. Compare-quotes lines up the real figures you were given against the scope fields that most often hide a gap. And the frozen-pipe checker returns the specific actions that address your building's actual risk factors, in the order they matter, instead of a generic winter checklist.

What these are for
Repair-or-replace and the frozen-pipe checker weigh the factors that actually decide an outcome and tell you what to ask a contractor: neither estimates project cost, because a believable figure would need to know things a form cannot ask. The quote-comparison tool structures the real quotes you already received so totals mean the same thing. The rebate calculator totals real, published Vermont incentive amounts for the utility and equipment you select: a genuine dollar figure, but a rebate amount, not a project-cost estimate.
The four tools
Two decide something, one calculates something knowable, and one organises what you already have.
| If you are asking… | Use | What it uses |
|---|---|---|
| Is this worth repairing, or should I replace it? | Repair or replace | Age, failure type and repair history: the factors a technician weighs |
| What will the rebates actually be worth? | Rebate calculator | Published incentive amounts, each with the date it was verified |
| Why are these two quotes so different? | Compare quotes | The real figures you were given, against the scope fields that matter |
| Are my pipes going to freeze? | Frozen pipe risk | The conditions that actually predict a freeze in this housing stock |
Why none of them estimate cost
An installed price depends on access, existing electrical and venting, what is found once a panel comes off, and what equipment is actually available that month. A calculator producing a confident figure from four dropdowns is producing a number, not an estimate, and the gap shows up when the real quote arrives.
The rebate calculator is the exception that proves the rule: incentive amounts are published facts with a source and a date, so they can be computed exactly. The difference between something knowable and something invented is the line these tools hold.
Your privacy, specifically
None of these tools makes a network request, sets a cookie, or stores anything: in your browser or anywhere else. You can disconnect from the internet and all four will still work. There is nothing to opt out of because nothing is collected.
Common questions
Do these cost anything or need a sign-up?
No to both. There is no account, no email address and no charge.
Does anything I enter get sent to you?
No. All four run entirely in your browser, make no network request and store nothing. You can disconnect from the internet and they still work.
Why does the rebate calculator give a figure but the others do not?
Because incentive amounts are published facts with a source and a date, so they can be computed exactly. An installed price is not: it depends on things a form cannot know, so producing one would mean inventing it.
How accurate is the repair-or-replace result?
The repair-or-replace tool weighs the factors, not your equipment. No tool can see corrosion, combustion readings or whether the part is even available. Use it to ask better questions: what is the expected life after this repair, and what does replacement cost today.
