AC Repair Process

Simple Process, Fast Results

First, we listen to what’s happening with your AC and schedule a time that works for you, often the same day. Our technician arrives with diagnostic equipment and a truck stocked with common parts for Mill Valley’s most popular AC systems.

Next, we run a complete diagnostic to find the root cause of the problem, not just the obvious symptoms. This takes about 15-20 minutes and prevents those frustrating callback visits when the same issue pops up again next week.

Then we explain exactly what’s wrong and give you an upfront price for the repair. No surprises, no hourly rates that keep climbing. Once you approve the work, we fix the problem using quality parts and test everything to make sure your system is running efficiently before we leave.

Everything Your AC Needs

Every AC repair includes a full system diagnostic, not just a quick fix of the obvious problem. We check refrigerant levels, test electrical connections, inspect your ductwork, and clean components that affect performance.

You get genuine manufacturer parts when replacements are needed, plus a warranty that covers both parts and labor. We also clean up completely before we leave and dispose of any old parts responsibly.

Most importantly, we explain what caused the breakdown and give you practical advice on preventing future issues. This might include simple maintenance tips or recommendations for upgrades that will save you money on energy bills and prevent emergency repairs down the road.

How much does AC repair cost in Mill Valley?

AC repair costs in Mill Valley typically range from $150 for simple fixes like replacing a capacitor to $800 for major component replacements like a compressor. Most common repairs fall between $250-$450. We always provide upfront pricing before starting any work, so you know exactly what you’ll pay. The final cost depends on what’s actually wrong with your system, not how long it takes us to fix it. We don’t charge by the hour, which means you won’t see your bill climbing while we work.
Yes, we offer same-day AC repair service throughout Mill Valley, especially during summer months when you need cooling most. We keep our trucks stocked with the most common parts for AC systems in your area, which means we can complete most repairs in a single visit. Emergency service is available seven days a week because we know AC problems don’t wait for convenient times. When you call before 2 PM, we can usually get to your home the same day. During peak summer demand, we prioritize emergency calls for homes with no cooling at all.
If your AC is under 10 years old and the repair cost is less than half the price of a new system, repair usually makes sense. Signs your AC needs immediate repair include no cool air, strange noises, frequent cycling on and off, or unusually high energy bills. However, if your system is over 15 years old and needs expensive repairs like a new compressor, replacement might be more cost-effective. We’ll give you honest advice about whether repair or replacement makes more financial sense for your specific situation, including how long you plan to stay in your home.
Our AC repairs come with a comprehensive warranty that covers both parts and labor for 90 days on most repairs, with longer warranties on major component replacements. This means if the same problem happens again within the warranty period, we fix it at no charge. The warranty also covers any related issues that stem from our repair work. We use manufacturer-backed parts whenever possible, so you get additional protection beyond our labor warranty. All warranty terms are clearly explained in writing before we start work, so there’s no confusion about what’s covered.
Yes, we repair all major AC brands including Carrier, Trane, Lennox, Rheem, Goodman, York, and others commonly found in Mill Valley homes. Our technicians receive ongoing training on the latest systems and carry diagnostic equipment that works with both older and newer models. We maintain relationships with parts suppliers for all major brands, which helps us get the right components quickly. Whether you have a basic builder-grade unit or a high-end variable-speed system, we have the expertise and tools to diagnose and repair it properly.
First, check your thermostat settings and make sure it’s set to cool with the temperature below your current room temperature. Then check your circuit breaker to see if it’s tripped. Look at your air filter – a completely clogged filter can shut down some systems as a safety measure. If these simple checks don’t solve the problem, turn off your AC and call us right away. Don’t keep trying to restart a system that’s not working, as this can cause additional damage. We’ll prioritize complete system failures and usually can get to your home within a few hours during business days.
