Longer Heat Waves, Bigger HVAC Challenges

Long stretches of triple-digit heat this summer, from June onward, have pushed home air conditioners harder than usual, and HVAC contractors say they're seeing more breakdowns as a result. Demand for cooling repairs, installs, and thermostat upgrades has jumped in cities like Atlanta, Austin, Washington D.C., Charlotte, and Baltimore, with places like Houston, Orlando, Raleigh, and Tampa seeing service requests rise more than 20% compared to last year. The core issue: problems that used to be minor, like a weak run capacitor, low refrigerant, a dirty condenser coil, or a worn motor, now cause systems to fail outright once they run nonstop for four or five days straight instead of just an afternoon.

Contractors interviewed for this trend say the fix isn't only about the equipment itself. Leaky attic ductwork, poor insulation, and drafty walls or ceilings force your system to work harder than it should, and an air conditioner that seemed fine when installed may now be undersized simply because the climate around it has changed. Sealing up those weak points reduces the heat your system has to fight in the first place.

None of this points to a specific rebate or deadline, but it's a reason to think about your own system's maintenance history if you've had a random breakdown this summer. Systems that get looked at every spring, before the heat sets in, tend to survive extended heat waves better than ones that only get attention after something already fails.
