If your AC isn’t cooling properly, is making unusual noises, or has weak airflow, it likely needs repair. Frequent breakdowns or rising energy bills can also signal deeper issues.
A technician can evaluate the system’s condition and recommend whether a repair or replacement is more cost-effective.
Some common signs include warm air blowing from the vents, inconsistent cooling throughout your home, strange noises (like banging or hissing), and a sudden increase in energy bills.
If you notice any of these issues, scheduling a professional inspection is the best way to prevent further damage.
The time required for a repair depends on the type and severity of the issue. Minor problems like thermostat adjustments or refrigerant recharges can often be fixed within an hour.
More complex repairs, such as compressor replacements or electrical issues, may take a few hours.
Technicians typically provide a time estimate after diagnosing the problem
Water leaks are usually caused by a clogged condensate drain line, a dirty air filter, or low refrigerant levels. When the drain line is blocked, condensation builds up and can’t drain properly, leading to leaks.
A professional can clean the line and check for any underlying issues to prevent future leaks.
First, check the thermostat settings to ensure they’re correct. If the settings are fine, the issue could be a refrigerant leak, a dirty evaporator coil, or a problem with the compressor.
