I am delighted with the service I received from the maintenance specialists while replacing the Thermocouple on my water heater. The work was done without issues and completed in less than 30 minutes. I will always recommend this company to anyone needing heating and cooling services. I would also like to mention how this company takes full accountability and responsibility if any repairs are not up to par. Not that I have had that experience. I read the reviews posted on BBB and was very impressed with how Thomas Hoffman and his team explained each situation and the subsequent resolution to the customer's satisfaction.
