Upgrade guides

Deep dives on the upgrades that matter most. Each topic explains what to consider, what it costs, and when it makes sense for your home.

Want numbers, not just guides?

Our tools help you estimate costs, savings, and payback for your specific situation.

Stop paying to heat (or cool) the outdoors. The foundation of any efficient home.

Air seal first—always. Adding insulation over air leaks is like putting on a sweater with holes.

Heat pumps, furnaces, and AC—understand your options and when switching makes sense.

Modern cold-climate heat pumps work efficiently down to -15°F. The math usually works if you have high gas prices or want AC anyway.

Your water heater uses 15-20% of your energy. Heat pump water heaters can cut that dramatically.

If your water heater is in a space with room temp air (garage, basement, utility room), a HPWH usually pays back in 3-7 years.

Generate your own power. Solar costs have dropped dramatically—but it's not right for everyone.

Depends on your roof, electricity rate, net metering policy, and upfront costs. Our tools can help you run the numbers.

Window replacement is expensive. Learn when it's worth it and when other fixes make more sense.

Rarely for energy savings alone—payback is 15-30 years. Replace for comfort, noise, or aesthetics. Air sealing and window film often give better ROI.

Going all-electric? Here's how to think about the transition from gas to electric appliances.

It depends on your electric rates, current equipment, and climate. Usually makes sense to electrify when equipment needs replacement.

Our My Plan tool helps you sequence these upgrades into a now/next/later roadmap based on your specific situation.
