We recently moved to Ottawa and bought our first home, which included an older central vacuum system. When we managed to test it with a new set of attachments, we found there was only limited suction, and it seemed like we might have to break down and buy a stand-alone vacuum cleaner.
Luckily for us, we were referred by another contractor to The Vacuum Guy, who offered to come and take a look at our system. He arrived on time, and within 15 minutes of showing up, had managed to inspect the canister and confirm that everything there was working just fine, find the source of the problems with suction (gaps in some of the existing tubing), and have everything fixed and back in perfect working order. He was even able to add an extra vacuum outlet for us in an area of the house where there wasn't one before, which makes a huge difference for overall convenience. Within an hour, all of the work was done and cleaned up, and we had a working central vac system that we could use throughout our entire house. The Vacuum Guy was quick, polite, and incredibly helpful -- highly recommended!
