“My main floor heat pump was not heating to the set temperature. The heat would not get any hotter than around 66 degrees. The technician Jeramee diagnosed the problem. He found the system had gone into lock mode. He was able to undo the locked mode and did a thorough full analysis of our heat pump. It is now working better than it ever did in maintaining the heat it is set at. I will definitely use Design Flow for any future issues I have with my heat pumps.”
