Very thorough and quick. Also very cordial and extremely reasonably priced!
Have had nothing but the BEST service from this company. They're always on time, always very neat, very thorough and take the time to check out everything, including a check if there is any kind of gas leak. They will show you their findings, even when they are good news.
We previously had Holiday Company install our new air conditioner, and 1-1/2 yrs later, it wasn't cooling. They came and charged me over $500 because "a screw became loose" and therefore all of our Freon escaped, so they needed to "replace" the Freon. I was young and dumb, and wish I would have contacted the BBB, because I believe it was Holiday's fault for not tightening the screw well enough when they installed!!!\
NOW I totally trust McQuerry's. They say it how it is, what could be, and what is all good and well. I won't go anyplace else.
