We have installed an air conditioner a few years back. It is in good condition, but recently I found that it has a leaky air duct. Though the AC is working perfectly, we didn't notice that before. But a big chunk of air is cooling the crawl space instead of our home. So it looks like we are in need of some AC repairs. I'm looking for someone who can help with general maintenance and upkeep. Does anyone have any good recommendations for HVAC repair service in Mississauga? Any help would be highly appreciated.
