Tru-Comfort replaces my old central air conditioning in 2005 and did a great job. I purchased a yearly service contract where they inspect the system, clean the coils, replace the filters and confirm its working property. I found it to be a good investment. Their service people are experts in their field and very considerate of your property. They even wear booties over their shoes when working in your house. I would recommend Tru-Comfort to my friends.
