"Our old furnace finally gave out mid-January. Next Phase had a new one installed the next day. The house heats evenly now and our gas bill dropped by a third. Couldn't be happier."
"They showed me exactly why my 22-year-old furnace wasn't worth repairing. No pressure, just honest numbers. The new system is so quiet I forget it's running."
"Professional from start to finish. They removed the old unit, installed a high-efficiency Carrier, pulled the permit, and cleaned up by 4pm. One day, done right."
"We went with a dual-fuel setup. Heat pump most of the year, gas furnace kicks in on the coldest days. Our energy costs are noticeably lower and the house stays perfectly comfortable."
"Got three quotes and Next Phase was the most thorough. They explained the difference between single-stage and variable-speed, and helped me pick the right fit. No upselling."
