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.

Kurtis and Matt replaced both my air conditioning unit and furnace, leaving me extremely satisfied. Their prior service on my equipment was always punctual, efficient, and professional. I highly recommend their services.

Matt, our installer from Superior HVAC Service, was professional, conscientious, friendly, and knowledgeable during the installation. This isn't the first time we've worked with them, and their consistent quality work and punctuality make them a preferred choice. Every employee we've interacted with has been great.
