Grand Alarms

My central vacuum power head became inefficient lately and had a weird noise, I called Grand Alarm customer service, my call was picked up by a representative within a minute, she was clear and polite, told me to bring it to their office, technician will look at it and fix it. Surprisingly they are open on saturdays, which is very convenient for us. We brought it over, the technician replaced the belt inside and explained the issue to us. Both receptionist & technician were very helpful & courteous, we felt welcomed. Very satisfied with the service overall.
