Frequently Asked Questions About AC Repair

What causes an AC unit to leak water inside?

Water leaking inside from your AC unit usually indicates a problem with the condensate drainage system. Here are some common causes:

• Clogged condensate drain line:
Algae, dust, and debris can clog the drain, causing water to back up and overflow.
• Cracked drain pan:
The pan collects condensation. A crack allows water to leak out.
• Disconnected drain line:
The line may have become disconnected from the unit or the drain.
• Frozen evaporator coil:
A coil frozen due to restricted airflow can lead to leaks.
• Low refrigerant:
This can cause ice to form on the evaporator coil, which then drips.

It's best to have a professional resolve AC water leaks.

How can I make my AC more energy-efficient?

Improving AC efficiency saves money and reduces your environmental footprint. Here's how::

• Regular maintenance:
Keep up with regular checkups and maintenance to keep your system in peak condition.
• Programmable thermostat:
Optimize temperature settings based on your schedule and occupancy.
• Seal air leaks:
Prevent air leakage by sealing gaps around windows and doors.
• Adequate insulation:
Ensure proper insulation to minimize heat gain and loss.
• Strategic landscaping:
Plant trees or shrubs to shade your home from direct sunlight.
• Ventilation:
Improve ventilation to remove excess heat and humidity, reducing reliance on AC.
• Energy-efficient windows:
Install double glazing to keep heat out during hot spells.
• Regularly clean/replace air filters:
A clean filter optimizes airflow and efficiency.
• Consider upgrading your unit:
Modern AC units offer significantly higher SEER ratings. If your unit is over 10 years old, consider replacing it with a high-efficiency model.

Small changes make a big difference!

What are the most common AC problems?

Air conditioners can experience a variety of issues, some more common than others. Here are some of the most frequent problems homeowners face:

• Refrigerant Leaks: Low refrigerant levels reduce cooling capacity and can damage the compressor. Signs include warm air, ice on lines, and hissing sounds.
• Frozen Evaporator Coil: Restricted airflow (often from a dirty air filter) can cause ice to form on the coil, hindering cooling.
• Dirty Air Filters: A clogged filter restricts airflow, reducing efficiency and potentially causing other problems.
• Faulty Capacitor: The capacitor helps start the motor. A bad capacitor can prevent the AC from turning on or cause intermittent operation.
• Compressor Problems: The compressor is the heart of the system. Issues here are serious and often require professional repair or replacement. Look for unusual noises, reduced cooling, or frequent cycling.
• Thermostat Malfunctions: An inaccurate or unresponsive thermostat can lead to inefficient cooling or prevent the system from turning on/off properly.
• Clogged Condensate Drain Line: The drain line removes condensation. If blocked, it can cause water leaks or damage to the system.

If you notice any of these problems, consult a qualified HVAC technician for diagnosis and repair.

What is a heat pump?

A heat pump is an HVAC system that can both heat and cool your home. It works by transferring heat between the indoor and outdoor air. During the summer, it acts like an air conditioner, moving heat from inside your home to the outside. In the winter, it reverses the process, extracting heat from the outdoor air and transferring it inside to warm your home. Heat pumps are very energy-efficient, especially in mild to moderate climates.
