We performed extensive renovations on a newly purchased house. Part of this work included replacing an aging furnace with a high efficiency model, a dying loud A/C with a new quiet model, replace wood fireplace with gas, draw gas line into patio for a bbq, and gas to the stove to replace an electric stove with a gas one.
Ultra Home was incredibly professional, and did an amazing job in all regards. Given that we were performing renovations (dusty), they recommended that some of the work which be done early, then after the dust had settled (literally) to complete the rest.
They drew gas pipes for all of the items (very well hidden), installed the Regency gas fireplace (which I bought through them) wonderfully, not taking any short-cuts, and drawing the air/gas exchange pipes *up the chimney* as oppose to through the wall.
I could go on and on, but in the end, I have to say: Great job on the installs, great job on the clean-up. Also, the first time I encountered a problem (a furnace code unrelated to their work) they were right on it, and helped out.
In my experience, a true 10 out of 10 if there ever was one.
