Air Conditioning Installation and Repair Services in Wauwatosa, WI

New Berlin Heating provides Wauwatosa and surrounding areas with first-class air conditioner, ductless split systems, and heat pump service including installations, repairs, maintenance, and replacements. We service all brands but personally recommend Carrier products.

Unlike most furnaces, air conditioners are complex systems that depend on many conditions to work optimally. That’s why it’s beneficial to have our professionals install your air conditioner. For the best performance and efficiency, a high-efficiency system has to be sized and installed correctly. When that happens, you can expect lower energy costs, increased comfort, and a reduced risk of equipment failure.

We also specialize in air conditioning repair, and our customers tell us they receive more than they pay for from New Berlin Heating—like simple tips from recommending filter changes at recommended intervals to how to control humidity when air conditioning isn’t needed. Best of all, we have tight control of what’s on our trucks. We’re able to fix nearly 95 percent of everything without having to leave your home for needed parts.

At New Berlin Heating, all pricing is in writing, and there are never surprises or hidden costs.
