Waukesha County HVAC Services You Can Trust
Over the Moon handles AC and furnace installs, emergency repairs, and everything in between for Waukesha County homeowners. Our technicians work on any type, model, or brand.
We’re also straightforward with you about what your system actually needs. If it’s a minor fix, we’ll tell you. If it can wait, we’ll tell you that too. You won’t leave a visit wondering if you just got talked into something.
Beyond repairs and installs, we offer annual tune-ups that catch problems before they become emergencies—IAQ testing, humidifiers, dehumidifiers, UV lights, and full ductwork cleaning.
Staying ahead of issues is almost always cheaper than reacting to them.

Seasonal Savings & Tips to Keep You Comfortable and Safe
Wisconsin weather doesn’t give you much runway. A fall tune-up booked in September is a lot less stressful than an emergency furnace call in January. We offer seasonal maintenance, electrical inspections, and current promotions to help you stay comfortable before the weather forces your hand.
