They called us back an hour later and said they had a technician come available and asked if we were interested in getting serviced right away at the same service rate. The technician came by, fixed our system and even gave us some tips on our system. Very professional and informative. Excellent experience."

"August 29, 2012 was a very hot day, in fact I believe it was over 100 degrees.  My air conditioner suddenly stopped cooling and started making some very scary noises.   I called my usual A/C guys and they couldn't respond for two weeks, so I started looking on Angie's List.  I called several companies, but they were understandably too busy to respond right away.  When I called McLay Services, Inc. they promised to have a technician at my house within two hours. 
In the meantime, I shut the system  down because it was making very loud sounds and not providing any relief from the heat.  Todd arrived right on time (if not a little early, thank goodness!)  Of course, when we turned the system back on it was not making the noises and was providing some cool air.  Nevertheless, Todd did a very thorough check of the system inside the house and out.  He checked the filters, air flow and several other items that could be issues. 
About the time he was starting to explain that it was an older unit and probably just couldn't keep up with this type of heat, the noises started again.  Todd shut the unit off and opened it up.  He found that a contactor was burnt and no longer working.  He replaced the contactor, checked the operation of the A/C unit which was working beautifully and has been working fine ever since. 
I was impressed by the quick response as well as by Todd's knowledge, skill, professional attitude and obvious pride in his work.
