Overview
- Technicians reported Tuesday that service demand has jumped sharply, with one six‑crew company handling about 50 calls a day as heat‑index values top 100°F and an excessive heat warning runs through Thursday night.
- Repair crews say the most common heat‑related failures are blown capacitors, tripped fuses or breakers, and dirty filters that reduce airflow and cause coils to freeze.
- Experts advise homeowners to first change air filters, check power and thermostat settings, clear condensate drains, and keep outdoor units free of grass and debris to lower the chance of a breakdown.
- Louisville has activated cooling options including all public libraries and community centers, city pools, more than 30 spray grounds, Meals on Wheels check‑ins for seniors, limited fan distribution, and a 211 hotline for resource help.
- If basic troubleshooting does not restore cooling, residents should call a licensed technician because the sustained strain on systems is likely to produce longer wait times, higher repair costs, and greater health risk for seniors and people with respiratory conditions.
