The questions to ask before you approve a big repair on an older system.
Some failures are small parts like capacitors, contactors or a clogged drain line. Others, like a failed compressor or a leaking coil, are major. Ask the technician to show you what failed and to write down the repair price.
An older system that needs frequent repairs, uses R-22 refrigerant, or struggles to keep up may be worth replacing. A newer system with one failed part usually isn't.
If you're quoted a replacement, ask what the repair would cost too. Ask for model numbers, a load calculation and warranty terms in writing so you can compare.
Our Repair or Replace guide walks through these questions and gives you a short list to take to your contractor. It doesn't make the decision for you, but it helps you ask the right things.
