Common AC Problems We Solve
Air conditioning systems are complex, but most failures stem from a set of common issues. Our experienced technicians have seen it all and can quickly identify the root cause of your system's malfunction. We handle a comprehensive range of AC problems, including:
AC Blowing Warm Air
One of the most frustrating AC issues is when the system runs, but the air coming from your vents is warm or room temperature. This often points to a refrigerant leak, a failing compressor, or restricted airflow due to a clogged filter or dirty evaporator coils. Our technicians will perform a thorough inspection to pinpoint the exact cause and implement the correct repair, whether it's sealing a leak and recharging the refrigerant or addressing a mechanical failure.
Strange Noises or Odors
Your air conditioner should operate with a consistent, low hum. If you hear grinding, squealing, or clanking, it’s a clear signal that a mechanical component, like a motor bearing or a belt, is failing. Musty odors often indicate mold or mildew growth in the ductwork or on the coils, while a burning smell could signify an electrical problem. We will immediately investigate these sounds and smells to prevent further damage and ensure your system’s safe operation.
AC Leaking Water or Refrigerant
Water pooling around your indoor unit is typically caused by a clogged condensate drain line or a frozen evaporator coil. While water leaks can cause damage to your home, a refrigerant leak is a more serious issue that harms the environment and your system's cooling capacity. Our team is trained to safely handle refrigerants, repair leaks, and clear any blockages to protect both your AC and your property.
System Short Cycling or Not Turning On
An air conditioner that turns on and off in rapid succession—a problem known as short cycling—can be caused by an oversized unit, a faulty thermostat, or a clogged air filter. If your system won't turn on at all, the issue could be as simple as a tripped circuit breaker or a more complex problem with the thermostat, wiring, or capacitor. We perform precise diagnostics to resolve these electrical and mechanical issues correctly.
Our AC Repair Process: What to Expect
We believe in transparency and keeping you informed every step of the way. Our repair process is designed to be straightforward and stress-free.
- Thorough System Diagnosis: Our technician arrives on time and conducts a comprehensive diagnostic evaluation of your entire AC system to accurately identify the root cause of the problem, not just the symptoms.
- Clear Explanation and Upfront Estimate: Once the issue is identified, we explain the problem to you in clear, easy-to-understand terms. We will then provide a detailed, upfront estimate for the required repairs. You will know the full cost before any work begins.
- Efficient and Professional Repair: With your approval, our technician will proceed with the repair using high-quality parts and industry-leading techniques. We work diligently to complete the job quickly while maintaining the highest standards of workmanship.
- Final System Testing: After the repair is complete, we don't just pack up and leave. We test your air conditioner to ensure it is running at peak performance, providing consistent and powerful cooling throughout your home.
Should You Repair or Replace Your Air Conditioner?
When faced with a significant repair, many San Dimas homeowners wonder if it's more economical to replace the entire unit. As your trusted cooling advisors, we provide honest guidance to help you make the best decision for your home and budget. We'll help you consider key factors:
- Age of the System: Most central air conditioners have a lifespan of 12-15 years. If your unit is approaching or has surpassed this age, replacement is often the wiser long-term investment.
- Frequency of Repairs: If you are calling for repairs multiple times a year, the cumulative costs can quickly add up, making a new, reliable system a more cost-effective option.
- Cost of the Repair: A common guideline is the "$5,000 Rule." Multiply the age of your AC unit by the estimated repair cost. If the total exceeds $5,000, replacement is generally recommended.
- Energy Efficiency: Older models are significantly less efficient than modern AC systems. A new, high-efficiency unit can lower your monthly energy bills, providing a return on your investment over time.

Ruben, went above and beyond to ensure that everything was handled seamlessly, demonstrating not just professionalism, but also a sincere dedication to customer satisfaction.
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.
