2. Prompt Dispatch

We route your request to our emergency response team and provide updates on arrival timing.

3. Comprehensive Diagnostic

Your technician inspects critical system components, including:

• Thermostat and controls
• Electrical connections

• Condensate drainage

Common AC Emergencies We Handle

Sterling’s hot, humid summers can push cooling systems to their limits. Some of the most frequent emergency issues we address include:

• AC blowing warm air
• System not turning on
• Frozen evaporator coils
• Refrigerant leaks
• Electrical component failures
• Clogged condensate drains causing water leaks
• Loud or unusual system noises
• Short cycling (turning on and off rapidly)

If your system is showing signs of failure, acting quickly can prevent further damage.

Repair vs. Replacement During an Emergency

In some cases, a repair will restore your system to reliable operation. In others, especially with older units or repeated failures, replacement may be the more cost-effective long-term option.

If replacement becomes necessary, we will:

• Review system age and repair history
• Compare repair cost vs. replacement value
• Perform proper load calculations for accurate sizing
• Explain energy-efficiency options
• Discuss financing solutions if needed

You receive clear information to make the decision that best fits your home and budget. We never pressure you into unnecessary upgrades.
