Customer Reviews for A-A Mechanical Heating Cooling Company

2/1/2007-"Was glad I called"

By philerup77 -

     "Spending a week plus in the low fifties and having two unsuccessful visits from another repair man brought me to my limit. Walter and A-A answered my call and were more than willing to assist even on a holiday weekend, which already increased my confidence considering my original repair man who had already been paid wasn't available till Monday. The service was great and I'm happy to say that my heat is still functioning. I was impressed how easily Walter was able to explain the problem and the solution in layman's terms allowing me to understand every step of the process.   A-A will be my first call the next time something breaks."

12/5/2006-"Why am I freezing? I'M CALLING A-A!"

By fmangayao

     "A-A was so quick and did a great job! My service person not only diagnosed the issue with my heater, he had the proper part already sitting in his tool box. It's unlikely I'll need A-A anytime soon since they've done fantastic quality work."

11/16/2006-"Professional and Very Helpful"

By mmakkar5 -

     "I had a very positive experience with A-A Mechanical. When my furnace broke on Sunday, I tried contacting another company I had used the last time and they never even got back to me after three attempts. Then I tried A-A Mechanical and their representative responded within 10 minutes and told me when he would be able to come. Their representative was very professional and he explained to me what he was doing and what I needed to do to prevent future problems with my furnace. He even picked up some filters for me since I needed replacements. I will not hesitate to contact A-A Mechanical the next time I have any furnace problems. Thanks."

2/6/2006-"Great response to a emergency"

By philipteng

7/20/2006-"great job"

By jtalan1971

     "A-A installed a new furnace for me. They really did a great job, arrived when then said they would, cost never changed, completed the job when they thought they would, cleaned up after themselves. They are easy to work with and above all, honest."

7/14/2006"Outstanding service"

7/13/2006-"Professional and efficient"

By mattbesuden

     "A-A has done HVAC work for me twice. On both occasions Walter was easy to get a hold of and contacted me if he was going to be late. He was able to work around my schedule as well.

Very adept at diagnosing the problems and fixing in a timely manner.

3/4/2006-"Excellent service!"

By zfabianczyk

     "I was very pleased with the service I received from A-A Mechanical. My heating and cooling system was installed about five years ago by Walter, and I recently called on him to check the system. He performed the check in a timely fashion on the day he promised he would. The service was excellent, quick, and honest. The price was very reasonable. I would definitely recommend A-A mechanical to anyone, and I will continue to be a happy customer of theirs. "
