 If you're standing there with a plunger in your hand, it's a sign you might have a plumbing problem. If your lights are the only ones on the block that are out, it's a sign you might have an electrical problem. And if you're buying a space heater for every room, it's a sign you have a heating problem. When you see the new Harp Services signs on the side of our trucks, you know if it's broken, it's about to get fixed quickly in the most cost-effective way possible. I'm Blair Harp. If you're having warning signs with your electrical, plumbing, heating, and cooling, Harp is your sign of relief. Harp on, job done.
