Similar to a value menu at nearby restaurants, charging a flat rate cost in place of an hourly cost makes available more value for our customers because nothing is excluded, the pricing is up-front, and it does not get modified. Regardless of the cost of parts or how much time it takes to finish the repairs, the price will not change. This is just one reason why A1 Chesney Service Experts Heating & Air Conditioning is the most trusted name in Calgary.
