Emily was wonderful! She was very polite, respectful of our house, and knowledgeable about our system. She took the time to explain the condition of our HVAC units and maintenance options. After a couple bad experiences with other HVAC companies, I am thrilled to have found a great company to work with going forward.

EVERYTIME they come through! Shout out to Kenny who has helped countless times from installing a new hot water tank after a leak to getting the hot water to turn back on so we can shower, this company is our go to. Everyone is so polite, helpful, and fast. They even respond to texts! Along with doing emergency and next day services, they solve big problems affordably. Highly recommend!

The 128 Team arrived right on time the first day of our install. They were polite, considerate of our home. They finished right on time the second day with our new heat pump and furnace fully functional. They demonstrated the new thermostat and how to operate and maintain our new system. We’d recommend 128 to anyone with HVAC needs.
