Your energy bill is the one expense you only see after you've spent it.

By the time the bill arrives, the money's gone. ThermoBudget shows you where you stand every day, while you can still do something about it.

1

Set your cap

Tell ThermoBudget the most you want to spend this month, like $150. We use your past bills to figure out how much of that goes to heating and cooling.

2

Watch it in real time

ThermoBudget estimates your spending from how your system actually runs. Get alerts at 50%, 75%, and whenever you're off pace.

3

Stay on track

One tap eases your temperature a couple of degrees. Or let ThermoBudget adjust automatically, within the comfort limits you set.

Questions

Will ThermoBudget make my house uncomfortable?

You set the comfort limits. ThermoBudget never goes past them, and you can override any change from the app or your thermostat.

How does it know what I'm spending?

ThermoBudget estimates cost from how long your heating and cooling runs, your equipment, and your local utility rates, then calibrates against your real bills each month. It's an estimate, not your utility's official bill.

Does it cover my whole bill?

ThermoBudget uses your past bills to account for everything else in your home, then budgets and controls the heating and cooling part, usually the biggest and most variable piece.

What do you do with my data?

We use it only to run your budget. We never sell your data.

My thermostat came with my apartment. Will it work?

Some building-managed systems don't allow outside apps yet. Pick "Provided by my landlord" when you sign up and we'll let you know as support expands.
