Repair or replace your AC: what to ask before you decide

A big repair quote on an older system raises the question: fix it again, or replace it? There is no single rule, but the right questions make the choice clearer.

Questions about your system

• Age. How old is the system? The date is often on the outdoor unit’s label, or the company can read it for you.
• Repair history. Has it needed repairs often in the last few years?
• This repair. What part has failed, and is it under the manufacturer’s warranty?
• Refrigerant. Which refrigerant does it use? Production of R-22 ended in the US in 2020, so a system that uses it can be more expensive to recharge.
• Comfort and bills. Does it keep the home cool and dry, and have your energy bills gone up?

Get both prices in writing

Ask for a written repair quote, and if replacement is suggested, a written quote for that too: brand, model, size, efficiency rating, what is included (removal, permits, ductwork, thermostat) and the warranties on equipment and labour. A replacement should be sized for your home; ask how they worked out the size.

616 AC companies in our directory list installation and replacement (as of November 6, 2026), and 373 AC companies mention financing.

Get a second opinion

For a large repair or a new system, a second opinion is normal and worth the time. Ask the second company to look at the same problem and price the same job, so you can compare like with like.

83 AC companies offer free second opinions and 370 AC companies mention free estimates.

Rebates and incentives

Utilities and government programmes sometimes offer rebates or tax credits for efficient equipment. They change often, so check with your utility and the official programme pages rather than relying on a sales quote.
