Can anyone recommend a good heating/ac company to do biannual maintenance and install thermostats?

I just installed 2 thermostats myself. Very easy to do. Took about 10 minutes each. I installed the "SmartTemp Programmable Heat/Cool Thermostat" from Lux. It is the "Smarttemp model 500" which rated very high in Consumer Reports.
You can get them for $42.99 at amazon.com
