Get Your Hearing Aids Working Again

When your hearing aids malfunction, every conversation becomes a struggle. Whether your devices are producing weak sound, cutting in and out, or have stopped working entirely, Optimum Audiology can help. We repair most hearing aid brands and offer flexible service options designed to get you back to better hearing quickly.

Dr. Kristi Mendoza and our team provide hearing aid repairs at our Apple Valley, Jess Ranch, Visalia, and La Verne locations. We also offer convenient curbside and mail-in repair services for patients who prefer to minimize office visits.

Common Hearing Aid Problems We Fix

Hearing aids are sophisticated devices that endure daily wear, exposure to moisture, and contact with earwax and skin oils. Over time, these factors can affect performance. Common issues we address include:

Sound Quality Problems

Weak output, distortion, or intermittent sound often stems from clogged receivers, damaged tubing, or microphone issues. Sometimes a thorough professional cleaning resolves the problem; other times component replacement is needed.

Physical Damage

Drops, impacts, and accidental exposure to water can crack casings, damage circuitry, or compromise seals. We assess the extent of damage and determine whether on-site repair or manufacturer service is the best path forward.

Battery and Charging Issues

If your hearing aids drain batteries quickly or won’t hold a charge, the problem may involve corroded contacts, faulty charging ports, or aging rechargeable cells. We diagnose power issues and recommend appropriate solutions.

Feedback and Whistling

Persistent whistling often indicates fit problems, damaged tubing, or earwax blockage. We identify the source and correct it through cleaning, refitting, or component repair.

Our Repair Process

When you bring your hearing aids to Optimum Audiology, we start with a comprehensive evaluation. Many issues can be resolved the same day with professional cleaning, minor adjustments, or replacement of wax guards, domes, and tubing.

For more complex repairs, we coordinate directly with manufacturers on your behalf. We handle packaging, shipping, and communication so you don’t have to navigate the process alone. Once your devices return, we verify proper function and perform Real Ear Measurement if programming adjustments were made.

Convenient Service Options

We understand that getting to the office isn’t always easy. That’s why we offer:

  • Curbside Repairs: Drop off your hearing aids without leaving your vehicle for quick assessments and minor fixes.
  • Mail-In Service: Ship your devices to us for evaluation and repair. We’ll contact you with findings and return your hearing aids promptly.
  • Telehealth Support: For troubleshooting that doesn’t require hands-on service, we offer remote consultations throughout Los Angeles, San Bernardino, Riverside, and Orange Counties.
  • When to Consider Replacement

While we repair most devices, hearing aids that are very old or have sustained extensive damage may cost more to fix than replace. We provide honest assessments and never recommend unnecessary repairs. If replacement makes more sense, we’ll discuss your options and help you find the right solution for your hearing needs and budget.

Your Questions Answered

Frequently asked questions

With over 30 years of experience, we understand you may have questions about hearing health, treatment options, and what to expect from your visit. Dr. Mendoza and our team have compiled answers to the most frequently asked questions to help you feel informed and confident about your care.

We repair most major hearing aid brands including Widex, Starkey, Phonak, Oticon, ReSound, Signia, Unitron, and Rexton. If you're unsure whether we service your brand, contact us and we'll let you know.

Minor repairs and professional cleanings are often completed the same day. More extensive repairs requiring manufacturer service typically take one to two weeks, depending on the issue and parts availability.

Repair costs vary based on the type of damage and whether manufacturer service is required. We provide estimates before proceeding with any work so you can make an informed decision.

Yes. We service hearing aids regardless of where they were originally purchased. Our goal is to help you hear better, whether you're an existing patient or new to our practice.

We assess each device individually and provide honest recommendations. If repair costs approach or exceed the value of your current hearing aids, or if your devices are technologically outdated, replacement may be the better investment.

In some cases, we can provide loaner devices while yours are being serviced. Ask about availability when you schedule your repair appointment.

Contact us to arrange mail-in service. We'll provide shipping instructions and evaluate your devices upon arrival. After diagnosis, we'll call with findings and cost estimates before proceeding with repairs.

Sometimes. Water damage severity varies widely. Minor moisture exposure may be remedied with professional drying and cleaning, while submersion often causes irreparable circuitry damage. We assess each case individually.

Store hearing aids in a dry, cool place when not in use. Remove them before showering, swimming, or applying hair products. Clean them daily and schedule regular professional cleanings to prevent wax and debris buildup.

We don't recommend DIY repairs beyond basic maintenance like changing wax guards or batteries. Hearing aids contain delicate components that require specialized tools and expertise. Attempted home repairs often cause additional damage.
