AC Stopped Working

5 Common Reasons Your AC Stopped Working Over Winter in Nampa, Idaho

As the summer approaches in Nampa, Idaho, and we prepare for the warmer months ahead, many homeowners find their air conditioners are not working as expected. Owyhee Heating and Air Conditioning is here to help you understand why this happens and what you can do to get your AC back in working order.

Common Reasons Your AC Stopped Working Over Winter

1. Lack of Use

During the winter months, your air conditioner sits dormant for extended periods. This inactivity can cause parts to seize up or become less efficient. Regular maintenance checks, even during the off-season, can prevent these issues.

2. Weather-Related Damage

Winter weather in Nampa, Idaho, can be harsh. Snow, ice, and freezing temperatures can cause significant damage to outdoor AC units. Components like coils and fins can be damaged by ice, and electrical connections can corrode due to moisture.

3. Debris Buildup

Leaves, dirt, and other debris can accumulate around your outdoor unit during the fall and winter. This buildup can obstruct airflow, damage internal components, and cause your AC to malfunction when you need it the most.

4. Rodent or Pest Damage

Rodents and other pests often seek shelter in warm places during the winter, and your AC unit can be an inviting spot. Chewed wires and nests can lead to serious damage and prevent your air conditioner from working correctly.

5. Refrigerant Leaks

Refrigerant leaks can develop over the winter, particularly if your AC unit has small cracks or worn seals. Low refrigerant levels can severely impact your system’s efficiency and cooling capability.

How to Prevent AC Problems Over Winter

  • Regular Maintenance: Schedule a tune-up with Owyhee Heating and Air Conditioning before the winter season and again before summer. Regular inspections can catch potential issues early.
  • Protect Your Unit: Consider using a cover for your outdoor unit during winter to protect it from snow and debris.
  • Clear Surrounding Area: Keep the area around your AC unit clear of leaves, branches, and other debris to ensure proper airflow.
  • Check for Pests: Inspect your unit regularly for signs of pests and take steps to prevent infestations.
