Purchased a heating and AC tuneup. While they pointed some things out that were wrong, it seemed like more of a scare tactic. They didn't really explain the issues...and my furnace didn't work after they came out. It seems they fiddled or bumped some wires and this caused the problem. When calling the company, they wanted to charge me again to come out and look at the problem. Since I wasn't satisfied I called a different company to diagnose the problem. and correct it. I think they need to pay for all the advertising they do...so maybe they try to scare you and or create problems.
