"We have an annual service contract with them. I just think they're great. They come in the spring and the fall for maintenance. The contract covers a fall checkup of the furnace, and a spring checkup on the A/C and I believe we get a discount on any service we might need, and they guarantee that they would come out quickly, that we'd be prioritized if we have a problem if we are annual maintenance customers. As with the installation of the system, they are just very trustworthy, efficient, friendly, and seem to do good work."
