Is it worth it? Bought our house a year ago and the A/C has been running fine. But it was installed in 1992 and we'd rather not wait until July to find out there's a problem. Seems like they're charging $100 just to show up and, and even if everything is fine, I'm sure they're not leaving w/o "recommendations."
Anyone know of reputable companies in the North Bethesda/Rockville area?
