Fast & Reliable AC Repair
An air conditioner breakdown, especially during a heatwave, requires immediate attention. Our team is equipped to diagnose and resolve AC issues quickly and effectively. We address all common and complex problems, restoring your comfort without delay.
We specialize in fixing:
- AC Not Blowing Cold Air: We pinpoint the cause, whether it's a refrigerant leak, a compressor issue, or a dirty filter.
- Strange Noises or Odors: Grinding, squealing, or musty smells are signs of trouble. We'll identify the source and perform the necessary repairs.
- Water Leaks: A leaking AC unit can cause water damage. We address clogged drain lines and other sources of moisture buildup.
- Frequent Cycling: If your unit turns on and off constantly, it's working inefficiently. We diagnose thermostat, electrical, or airflow problems.
- High Energy Bills: A sudden spike in your utility costs often points to an inefficient AC system in need of professional service.
Preventative AC Maintenance & Tune-Ups
The best way to avoid costly repairs is through regular, preventative maintenance. An annual AC tune-up is a crucial investment in your system's longevity and efficiency. Given Walnut's warm climate, ensuring your system is prepared for the summer demand is essential. Our meticulous tune-up process is designed to catch small issues before they become major problems, improve performance, and lower your energy consumption.
Our maintenance service includes:
- Cleaning condenser and evaporator coils for optimal heat exchange.
- Checking and verifying refrigerant levels.
- Inspecting and tightening all electrical connections.
- Lubricating moving parts to reduce friction and wear.
- Cleaning or replacing the air filter for improved airflow and air quality.
- Calibrating the thermostat for accurate temperature control.
- Testing the complete system to ensure it operates safely and efficiently.
Expert AC Installation & Replacement
When it's time to upgrade or replace your aging air conditioner, a professional installation is key to its performance and lifespan. We help you select the right high-efficiency system for your property's size and cooling needs, ensuring you get the most value from your investment. We handle the entire process, from removing the old unit to installing and commissioning the new one.
Deciding whether to repair or replace can be difficult. A helpful industry guideline is the "$5,000 Rule." To use it, simply multiply the age of your AC unit in years by the estimated cost of the repair. If the total exceeds $5,000, replacement is often the more financially sound decision. For example, if your 10-year-old unit needs a $600 repair (10 x $600 = $6,000), investing that money into a new, more efficient system is likely the better long-term choice.

Frequently Asked AC Questions
How often should I have my AC serviced?
For optimal performance and to prevent breakdowns, we strongly recommend having your air conditioning system professionally serviced once a year, ideally in the spring before the heavy cooling season begins in Walnut.
What are the signs that my AC needs to be repaired?
Common warning signs include warm air coming from vents, weak airflow, unusual noises like grinding or squealing, strange odors, moisture or leaks around the unit, and a sudden increase in your electricity bills.
When is it time to replace my air conditioner?
Consider replacement if your unit is over 10-12 years old, requires frequent and expensive repairs, is no longer cooling your home effectively, or is driving up your energy costs significantly. Applying the "$5,000 Rule" can also provide a clear financial justification for your decision.

I can't recommend Piggies air Conditioning/Ruben highly enough. If you're looking for someone who combines expertise with exceptional service, look no further. They are a true example of what outstanding professionalism should be.








The technician arrived on time, which I really appreciated given how crucial air conditioning is in this heat. Ruben was professional and friendly, explaining what he was doing throughout the process. The issue I had was diagnosed fairly quickly, and they provided me with a few options on how to fix it. The pricing was transparent, and I didn't feel like there were any hidden costs, which is always a plus when it comes to service calls like these. Highly recommend this company!




1st & foremost, huge shout out to Ruben thank u so so much for reaching out & making things happen SO FAST! I was so surprised since i had reached out to a couple different places who lagged on even answering calls, messages, etc.
Ruben was also very informative & taught me ALOT that i didnt know about.
Also cant leave the amazing Luis & Miles out of
this review.
They came, they saw, they conquered!
And they worked pretty swiftly too, felt very comfy around em, loved their personalities, great attitude, work ethic, professionalism, had some really good convos & they still got the job done lightning fast
SUPER HUGE SHOUT OUT & THANKS for everything guys! Definitely recommending u guys to everyone i know.




recommendations and feedback. The actual installation was painless and unremarkable, his AC experts got it done, got it cleaned and most importantly got it right. Rueben even went a step further to assure we had
protection from the coming rain, that is service unheard of these days. His price was competitive and a REAL value for the service we recieved. Using anyone else for your AC needs, would be a huge mistake. We thank them again and will recommend to everyone.




Echoing a lot of the other reviews here, Piggies Air Conditioning responds so quickly to requests (even though I actually accidentally sent in multiple requests on my side without responding, oops!)
They were able to come do a FREE energy audit and initial inspection on the same day and Ruben was amazing at explaining his thoughts on our house's situation and what he thought was worth the money and wasn't worth the money.
I truly felt like he was trying to help me find the best solution to our issues instead of just trying to upsell us on everything and anything.
I'm definitely recommending this business to anyone I know if they want a trustworthy and realistic service, value, and quality.
