We have had Stan's Heating and Air Conditioning out twice and they deserve five stars. We had them out to check our heating in the fall and we had never used them before. They came out and looked at our A/C also but did another check on it in the spring when it would be used. They have done a good job, and we have a filter up in the attic that needs to be vacuumed and we don't like to get on a ladder in the attic so they do it for us. They are polite and the work doesn't take long with them.
