 Trustindex verifies that the original source of the review is Google. Michael Carpenter was awesome and helpful. We were looking for additional air quality cleaner/improvements and he talked me through the options and let me do my homework and settle on the right one without pressure. Once we identified it, he was able to get back out the next week and install it. Really happy with Southwest Heating and Cooling.
