AC Parts We Replace

When your air conditioner struggles to keep up, worn or malfunctioning components are often the root cause. Instead of replacing the entire unit, our team can swap out individual parts to restore performance, improve efficiency, and extend the life of your system. We carefully assess your AC’s condition and recommend targeted replacements that get results without unnecessary costs. Some parts we commonly replace include:

  • Compressors – The heart of the system, responsible for circulating refrigerant
  • Blower Motors – Push conditioned air through your home
  • Fans (Condenser and Evaporator) – Help dissipate heat and keep airflow steady
  • Coils (Evaporator and Condenser) – Critical for heat exchange and refrigerant cycling

From diagnosis to installation, we handle every step with attention to detail and a focus on your comfort. We also offer coil cleaning, refrigerant recharging, and electrical testing to prevent further issues.

Frequently Asked Questions About Air Conditioner Parts Replacement

What are the most common AC parts that need replacement?

Commonly replaced parts include capacitors, contactors, fan motors, thermostats, and relays. These components wear out over time or fail due to electrical issues.

How can I tell which AC part is failing?

Strange noises, reduced airflow, poor cooling, or short cycling are all signs something’s wrong. A licensed HVAC technician can run diagnostics to pinpoint the faulty component.

Is it better to replace a single part or the whole unit?

If your system is relatively new and the problem is isolated, replacing a single part is often the most cost-effective choice. Older units with frequent issues may benefit from full replacement.

Do replacement parts come with a warranty?

Yes. Most parts carry manufacturer warranties, and trusted HVAC companies usually include a workmanship guarantee for any replacement services they perform.
