Heating

We started with oil heating, and are still the experts in our area, but over the years we’ve learned what works in Lake County homes, and what doesn’t. Our team listens, advises honestly, and installs systems built to last through cold winters.

Solar

Not every roof is right for solar panels. That’s why we also install ground-mounted systems that let you capture the sun’s energy from the best angle, no matter what your roof looks like. Going solar still makes good sense with costs of utilities continuing to rise.

Water Heaters

Your water heater is easy to forget, until it stops working. We help Lake County homeowners choose the right system for their needs, whether that’s a traditional tank or a more efficient tankless unit. And when it’s time to replace yours, we’ll walk you through the options that fit your home and budget.

Back-Up Power

Power outages happen in Lake County. When they occur, a whole-house generator or battery system keeps your heat, lights, and essentials running smoothly. We’ve seen what a difference backup power makes for families during bad weather or high temperatures. We’re here to help you stay prepared.
