Our water heater tank broke down and had to be replaced. We wanted to own the tank instead of renting. I searched for a reliable company in Home Stars and called to several potential contractors. Vicky, an office manager from Cumming Home Heating and Cooling was the best. She was friendly, knowledgeable, and very positive. They had no problem to come on Saturday (our tank broke down on Friday), replace it and take out the old one back to the rental company. Owner Chris and technician Geoffrey were prompt on time and did a very good job. They were fast, accurate, very polite. They could answer any cooling and heating systems related questions and gave very useful tips on using them. Additionally, they checked humidifier, furnace, pool heater and gave some advices on use. Overall, we are very lucky and happy that we found them on the HomeStars and would highly recommend them to everyone.
