Sometimes the number 23 can be a pretty big deal.

In basketball, it’s been the number of superstars Michael Jordan and LeBron James. In the series “Lost,” it was a possible clue to all the weirdness. In calendars, it’s a reminder that the new year is coming up way too quickly.

And now, it’s also a really great opportunity for energy efficiency.

Our friends at Efficiency Works recently started a new offer of “$23 in 2023.” That means you pay just $23 for a home energy assessment (instead of the usual $60) so that you can find out where you can save energy. And once you know, an energy advisor can help you find rebates on improvements that can make a difference to your home, like new windows, insulation or air sealing upgrades.

Not a bad way to go into the year, is it?

If that’s caught your interest, it’s easy to get started. Simply go to the online Efficiency Works application and sign up for an assessment before Jan. 31, 2023 to get the limited-time discount. If you’re not sure whether you’re ready for an assessment yet, following that link will also give you the opportunity to set up a free talk with an energy adviser who can explain things further and help you decide what you need. (And if you decide you’re looking to make smaller tweaks for now, the Efficiency Works Store also has a lot of savings to offer for simple energy-savers like LED light bulbs or smart thermostats.)

So as ’23 approaches, see what $23 can do for you.

You might just find we’ve got your number.
