How the San Gabriel Valley’s Weather Leads to AC Problems
As we said earlier, it gets hot in the San Gabriel Valley. It’s not unusual for temperatures during the summer to reach the high 90s. This means your air conditioning needs to run for hours on end, often without a break. This constant use can put stress on motors, capacitors, coils, and other critical components inside the unit.
Even the best units out there can only handle so much when it comes to dust, pollen, and outdoor debris common in San Gabriel Valley. These environmental elements can collect on condensers and filters, and over time, this reduces airflow, making the system work harder than it should.
Signs You Need to Call an AC Repair Company
We don’t expect our customers or the average homeowner in Pasadena or Altadena to be experts on air conditioning malfunctions. That’s what Multi Air is here for. That said, we want to make sure you know what problems can crop up so that you can be on the lookout. If you are experiencing one or more of these signs, it’s time to call us right away:
- Uneven temperatures throughout your home
- Rising utility bills
- Weak airflow from vents
- Excess humidity indoors
- Water pooling around the AC
- Frequent short cycling
- Your Pasadena AC making noises it shouldn’t

- An air conditioner running but not cooling in Altadena
- A South Pasadena AC fan not spinning

Should You Repair or Replace Your Air Conditioner?
In most cases, air conditioners in Pasadena can last 10 to 20 years. This means repairing your existing system is often the most practical and cost-effective path forward. Here is how to tell when it makes the most sense to choose AC repair over AC replacement:
- The system is less than ten years old
- The repair is relatively minor
- The equipment has been maintained regularly
- Energy bills have remained reasonable
If repairs are becoming frequent or your equipment is nearing the end of its lifespan, replacement may be worth discussing. Our team can help you compare the two options and determine which makes sense for your home and budget. We’ll always provide our honest, professional opinions to help you make the best decision.

- Change your air filter regularly

What to Expect for AC Repair Pricing in Pasadena
At Multi Air, we believe wholeheartedly in pricing transparency. That's why we’re upfront about charging a $95 dispatch fee for diagnostic visits.
Costs for air conditioning repairs in the San Gabriel Valley vary depending on the issue and the parts required. Many minor repairs and routine fixes fall between $150 and $600. More extensive repairs involving major components can range from $1,500 to $3,500, with some repairs costing more.
If replacement is the better option, a new system generally costs between $6,500 and $15,000, depending on equipment size, efficiency, and installation requirements.
Why You Shouldn’t Repair Your Own Air Conditioner in Pasadena
We know that air conditioning repairs can get costly, but attempting a do-it-yourself (DIY) approach is rarely the best course of action.
Air conditioners contain electrical components, moving parts, and refrigerants that can create safety risks when handled improperly. In most cases, DIY repairs can void your manufacturer's warranty, leaving you fully responsible for future repair costs. Many HVAC parts are also not readily available to the general public, making it difficult to get the correct replacement components.
Without proper diagnostic equipment and training, it's also easy to misidentify the problem and accidentally create additional damage. What starts as a simple repair can quickly become a much larger and more expensive issue.

Frequently Asked Questions
How long will it take you to fix my AC unit?
How long it takes to fix your AC depends on the problem. Many common repairs can be completed during the initial service visit. If special parts need to be ordered, the repair may take longer.
Should I turn off my AC if it’s covered in ice?
Yes. If your AC is covered in ice, you should turn it off immediately. Ice buildup often points to airflow problems, refrigerant issues, or mechanical failures. Continuing to run the system can cause additional damage.
Why is my air conditioner running but not cooling?
If your air conditioner is running but not cooling, the cause could be a dirty air filter, a refrigerant leak, a frozen evaporator coil, a faulty thermostat, or a failing compressor. A professional inspection is usually needed to pinpoint the exact issue.
Is it worth repairing an air conditioner with R-22 refrigerant?
Whether it is worth repairing an air conditioner with R-22 refrigerant depends on the system's age and the required repairs. Because R-22 has been phased out, refrigerant costs are much higher than they once were. In many cases, replacement may be the more practical long-term option.
What’s the most common AC repair in Pasadena?
The most common AC repairs in Pasadena involve failed capacitors, refrigerant leaks, clogged drain lines, dirty coils, and worn contactors. Long cooling seasons and heavy system use can contribute to these problems.
Can you just add more refrigerant to my system?
No. Simply adding more refrigerant is usually not a permanent solution. Air conditioners do not consume refrigerant during normal operation. If levels are low, there is likely a leak that should be located and repaired.
What’s making my AC trip the breaker?
If your AC is tripping the breaker, it may be drawing more electrical current than it should. Common causes include a failing compressor, a faulty capacitor, an electrical short, a dirty condenser coil, or blower motor problems.
Why is there no air pressure from my vents?
If there is little or no air pressure from your vents, the problem may be a clogged air filter, blocked ductwork, a failing blower motor, closed dampers, or a frozen evaporator coil restricting airflow.
What’s the best way to avoid air conditioner breakdowns in Pasadena?
The best way to avoid air conditioner breakdowns is through regular maintenance. Annual inspections, routine filter changes, and addressing small problems early can help reduce the risk of unexpected repairs in Pasadena.
Is it okay for my AC unit to leak water?
No. It is not normal for your AC unit to leak water. Water leaks are often caused by clogged condensate drains, damaged drain pans, frozen coils, or installation issues that should be inspected promptly.
Why is my air conditioning system constantly turning on and off?
If your air conditioning system is constantly turning on and off, it may be short cycling. This can be caused by a dirty filter, thermostat issues, oversized equipment, low refrigerant, or electrical problems.
Why does my AC struggle to cool the upstairs of my Pasadena home?
Your AC may struggle to cool the upstairs of your home in Pasadena because heat naturally rises. Poor insulation, inadequate airflow, ductwork issues, sun exposure, or an improperly sized system can all contribute to warmer upstairs temperatures.
