This company will send out unqualified workers, spend 6 hours ( mostly to figure out what's wrong, tell you that you need parts on your furnace that you don't need and not leave you a bill, get bill for 900.00 in nail. I put back on the parts the serviceman said were bad, I'm a plumber and knew what was wrong with it. No apology from the company. Nothing but crooks. 6 hours to replace pressure switch ( 3 tubes to unplug and two screws to screw in) and install a new thermostat ( two wires and mount to wall) , thief's of a company. On top of that I had to take off their parts and install mine back on and told me well that comes with owning a home. Guess hiring someone to do it means that you have to redo it after comfort systems leaves. It's a crime to falsify to a customer that they need new parts when they don't. Yeah my parts over a year later still working! read more
