We recommend twice-yearly maintenance: once in spring (March–April) before the summer cooling season, and once in fall (October–November) before the heating season. Texas summers are hard on equipment — don't skip the spring check.
Common warning signs include: the system running but not cooling the house, warm air from vents, strange noises (grinding, squealing, banging), the system short-cycling on and off frequently, ice on the unit, water leaks, and significantly higher electric bills.
