I like the guys at Team Electric, Plumbing & Air. I have a platinum contract with them, so they come out twice a year to check my heating and cooling system, which they did a few months ago. They performed maintenance on the unit, and everything went well. They showed up on time, came in, and verified the system was blowing cool air. It's very important for me that they stick to their appointment time and not change it. I also use them for plumbing, as well. When we're not here during the winter months, they shut the system off for the season. Then around March or April, they turn it back on, but always checking the pipes for any leaks or other issues. They do a good job, and I'm going to keep using them.
