Since moving to this house more than 4 years ago, I've been plagued with non-stop issues with my air conditioning. I originally just utilized whatever company my home warranty would contract to fix my problems or to come out for maintenance. However, whenever the A/C would die in the middle of summer, those same companies would not send anyone out, claiming they were booked for more than a week and that I would have to wait without A/C in Houston summer until then. Those companies also would look at my system, call it fixed, and leave without an explanation or a guarantee. During this time, there was one period it broke down every week after hours on Fridays as if on schedule.
In desperation and frustration after the poor experiences I've had with previous companies, I managed to find Stalwart A/C and Heating. They were the only ones that picked up *and* were willing to send someone (Michael) during that busy time. He promptly diagnosed, explained in a level I could understand, and fixed the issue. He also gave me a price I could not refuse (for the cost of a home warranty contract request for one visit, Stalwart waived the fee for that particular fix and would cover not one, but two maintenance visits for the year). Occasionally during seasonal maintenance, I'd get Geoff, who also had the same expertise and bedside manner as Michael, which helped further convince me that I'd settled with the right company for my HVAC needs.
Most recently, a Trane that we installed broke under warranty, but it was a Saturday at 5 pm and the parts necessary to fix it weren't available until Monday. Raymond, who took my case after hours, was able to troubleshoot and assess the situation professionally and explain the situation to me. If there was anything that I asked regarding what was covered, what isn't covered, etc. that he did not know, he made sure to get the answer from someone who knew promptly. Additionally, he went above and beyond of his own volition to ensure that I, a customer that he met for the first time, would get some level of comfort until the unit could be fixed. Walter, who was assigned to finish the fixes on Monday, drove all across the Houston area to obtain the one part necessary for the final repairs. Isabel made sure to call and text to keep me updated on any delays or developments on the scheduled appointment.
Any time someone entered my home, they came prepared with shoe coverings and they made sure to clean up any mess or debris that may have come from their work. Any time I had questions about something I read that I was curious about installing, they were able to answer my questions and also give me a plain assessment instead of giving me false promises for a quick buck.
In all instances with each point of contact I've had with Stalwart, I have been met with professionalism, transparency, friendliness, care, accountability, and a depth of knowledge that show me that they aren't like those HVAC companies bought by private equity firms who just want a return on their monetary investment. The folks at Stalwart care about doing their job right.
