: Can I save money by only replacing my outdoor AC unit?

Replacing only the outdoor unit can reduce your system's efficiency by up to 15% and may lead to premature mechanical failure. To ensure peak performance and protect your manufacturer’s warranty, it is essential to replace the indoor cooling coil at the same time as the outdoor component.
