Several years ago, our furnace died on one of the coldest nights of the year. We called our general contractor for advice (Mike Mazza of Mazza Renovation -- we thoroughly recommend him as well!), and he gave us Lou's number at Dave White Heating. Lou was came out the same day and had us toasty warm in no time, at what we thought was a thoroughly reasonable cost. We were immediately struck by how truly nice and professional he was and filed his number away for future use.
The following summer, our air conditioning unit started freezing over during a major heat wave. We immediately called Lou, and sure enough, despite being an incredibly busy time of the year, he was out the next day, found the coolant leak and saved us having to replace the air conditioner.
Then this week, after the earthquake, we found a liquid overflowing in our furnace room from some point in the air conditioning system. Worried that something had cracked during the quake, we called Lou on a Saturday, expecting to leave a message and hear from him on Monday. To our happy surprise, he called us back within the hour, and walked my husband through things to look for ("let's see if I can save you the cost of a service call" was his response). Sure enough, the problem was a simple one (a plugged drainage elbow) that we were able to fix ourselves. Not many contractors would have this kind of consideration and take that kind of time to help out a stranded homeowner.
We can't recommend Lou enough. He's professional, incredibly courteous and thoughtful and knows his stuff. Thanks again, Lou, for saving our bacon 3 times now!
