Why don't you charge by the hour? Similar to a value menu at nearby restaurants, charging a flat rate cost in place of an hourly fee makes available more value for our customers because everything is included, the pricing is up-front, and it does not get modified. Regardless of the cost of parts or amount of time it takes to make 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. Back To Frequently Asked Questions
