Air Conditioner Installation in Calgary

A: Choosing the right air conditioner depends on several factors including the size of your home, insulation, number of windows, ceiling height, and even which direction your house faces. At Wiehler, our technicians assess your space and perform load calculations to recommend a unit with the right capacity—measured in BTUs (British Thermal Units). Oversized units waste energy and cycle too quickly, while undersized units won’t keep your home cool. We make sure you get the most efficient system tailored to your home and budget.

A: Before your scheduled installation day, we recommend clearing the area around the outdoor condenser unit and making sure there’s easy access to your furnace or air handler indoors. If possible, secure pets and move furniture away from work zones. Don’t worry—our team is respectful, clean, and always communicates arrival times so you’re not left guessing. We also provide a checklist in advance to make preparation simple and stress-free.
