Mike H. came for usual heater checkup. Timely, friendly, knowledgeable, and didn't just rattle around for a few minutes and charge us. He really checked things out, cleaned things, taught us things we hadn't known, and answered extra questions. Quality company, from first call, to contract (decent prices), to maintenance call, to followup (we had a little glitch with cranky Infinity thermostat). Yay, Mike H.! Yay, Stark!
