 Have you been brainwashed by plumbers or heating and air people thinking sky-high pricing is normal? Nonsense. I'm consumer advocate Tom Martino. Master Services wants to change your mind with their lowest price guarantee. And they're not kidding, not even a little. Like a new AC starting at below $3,000 fully installed. And sewer line repairs? I know you've heard the nightmares, but how about a dream come true with Master Services?
