 Trustindex verifies that the original source of the review is Google. Larry came to my house and fixed my HVAC by changing out a capacitor. He didn't have the exact one with him so he put in a temporary one to keep me going on a hot day and then came back and put in the exact one a couple of days later at no extra charge.

A few months later, I had a moisture sensor trip. He and his son took a look, gave some good ideas about a possible roof leak and didn't even charge me for coming out.

He's super reasonable and very honest.
