With the complete setup, we bought the bosch heat pump here. The whole process went smoothly, and the entire team was patient and able to make it as smooth as possible. We selected the most cost-effective option, as well as a fair price for the job.

They saved me tons of time and effort! I originally planned to conduct my AC repair on my own, but my friend recommended that I hire instead of them. It was quite efficient and incredibly rapid. Thanks!

If the hot water heater's pilot light goes out, Leo explained how to re-start it. This is a great company.

We had a complete HVAC system replacement - furnace, heat pump, coil, thermostat, and everything to the latest pipe. They made a smooth transition for us. First, their specialist came to measure the room. The replacement was the next day, and it took quite a while. But I'm actually glad they double-checked everything.

After coming home to a wet floor and leaking hot water tank we called Superior and Kurtis was here within 1/2 hour. Unfortunately we needed a replacement but fortunately they could be here the next day. The next day the guys showed up and had us up and running in just over an hour.We will definitely keep these guys on our speed dial
