Repair or Replace? How to Decide

Sometimes, an air conditioner is simply too old or inefficient to justify the cost of repairs—especially if it still uses R-22 refrigerant or breaks down frequently. We’ll help you weigh the cost of the repair against the cost of replacement, so you can make an informed choice.
