“My husband & I stay up on maintenance for our HVAC system because our home is about 14 years old, so we have had many HVAC companies come out and conduct maintence services for us. WeatherWise Heating & Cooling us by far the most professional and honest company that we have dealth with, so far. James was our technician yesterday. He was not only friendly and curteous, he was also extremely professional and very respectful of our property. He explained what he would do and kept us up-to-date after working each of our systems - we have two AC units and two furnaces. He also provided us with good and fare estimates for future projects.

I will use this company again for any and all HVAC services that we will need. The office staff that I spoke with, when I called to schedule the initial service, was also extremely professional, polite and did a great job to show care of our HVAC needs.

This company is top notch! I plan to install a tankless water heater soon and will definately use these guys for that service, as well.“
