Top-notch work; technicians that are courteous, well-skilled and won't gouge. I'd use Air Assurance or recommend them anytime. Explanation: I've been a customer on a few occasions, today being the latest. My water heater failed after many years of service. Naturally, I turned to Air Assurance. The experience was the usual excellent experience from dispatch to payment (and beyond!). Will S. came exactly on-time, surveyed the situation and then sat down with me to discuss options. I thought it might just be a pilot light gone out, but he explained that there was a leak & the tank had outlasted it's predicted lifetime. He asked questions about my usage needs, plans for how long I would be remaining in the house, etc. Then, he clearly explained the available options and the pros/cons. After helping me determine the best option, he got with the office, arranged for the selected tank to be brought to him and began working to remove the old unit. During his work, I mentioned I was considering replacing my air conditioner. Will took the initiative, offered to arrange for a consultant to come out & did so when I agreed. Some time later, I had a thorough, excellent conversation with Stephen T. when he came out too. (Stephen was just as great to work with, but I could write an entire review just for him.) During the time both men were here, each was super courteous, professional and conscientious (like using little booties to keep my house clean). Will's completed work was excellent. He took the time to explain the functions of the new unit, caution about raising the temperature slowly to where I was comfortable without getting burned, and initiated the scheduling of a city inspector based on my availability. I hope I don't need service for awhile. But when I do, I'll be calling Air Assurance and requesting Will.
