“We had Care One come out to replace the gas valve and burner on our water heater. They gave us an honest quote comparing replacing the parts versus replacing the water heater altogether. While they were working they discovered another issue that had been causing a slow leak for who knows how long. Luckily they had the parts they needed and were able to quickly fix that as well. Very happy with Care One's service. Will definitely recommend them to local friends and family.”
