Our certified technicians have the experience and tools to accurately identify the root cause of any problem and provide lasting repairs that restore your system’s efficiency and performance.

Common Heat Pump Problems We Solve in San Dimas
Heat pumps are complex systems, but most failures stem from a handful of common issues. Our technicians are experts at pinpointing and resolving these specific problems to get your comfort back on track.
The Heat Pump Won't Turn On
One of the most frustrating issues is a system that won't start at all. This often points to an electrical problem.
- Common Causes: Tripped circuit breakers, faulty wiring, a malfunctioning thermostat, or a failed capacitor or contactor.
- Our Solution: We perform a thorough electrical diagnostic, safely tracing the issue from the thermostat to the unit itself, repairing or replacing any faulty electrical components to restore power and operation.
The Unit is Making Strange Noises
Unusual sounds like grinding, squealing, or loud clanking are clear indicators that something is wrong internally. Ignoring these noises can lead to more significant and costly damage.
- Common Causes: Worn-out motor bearings, loose internal components, a failing compressor, or debris in the fan unit.
- Our Solution: Our technicians will carefully inspect the internal components, identify the source of the noise, tighten loose parts, lubricate moving elements, and replace any failing motors or bearings.
Inadequate Heating or Cooling
If your heat pump is running but the air coming from your vents is lukewarm, or it can’t reach the temperature set on your thermostat, its performance is compromised.
- Common Causes: Low refrigerant levels due to a leak, a clogged air filter restricting airflow, a malfunctioning reversing valve, or a failing compressor.
- Our Solution: We begin with a full system evaluation, including checking refrigerant pressures and inspecting for leaks. We will repair any leaks, recharge the system to factory specifications, replace dirty filters, and ensure all components are functioning correctly.
The Outdoor Unit is Frozen
While a light layer of frost can be normal, a unit completely encased in ice indicates a problem, especially in San Dimas's mild climate. This severely restricts airflow and can damage the compressor.
- Common Causes: Low refrigerant, dirty coils, a malfunctioning defrost control board, or a failing outdoor fan motor.
- Our Solution: We will first safely thaw the unit. Then, our technicians will diagnose the cause, whether it requires repairing a refrigerant leak, thoroughly cleaning the coils, or replacing a faulty component in the defrost system.
The System is Short Cycling
Short cycling is when your heat pump turns on and off in rapid, frequent bursts without completing a full heating or cooling cycle. This puts immense strain on the compressor and wastes energy.
- Common Causes: A clogged air filter, an incorrectly calibrated thermostat, low refrigerant levels, or an oversized unit.
- Our Solution: We analyze the entire system to determine the cause of the short cycling. This includes checking for airflow restrictions, testing the thermostat’s accuracy, and verifying proper refrigerant levels to restore normal cycle times.
Should You Repair or Replace Your Heat Pump?
This is a critical question for many homeowners in San Dimas. As your trusted local experts, we provide honest guidance to help you make the most cost-effective decision for your home. We consider several key factors:
- Age of the Unit: Most heat pumps have a lifespan of 10-15 years. If your unit is approaching or has surpassed this age, replacement might be a more financially sound long-term investment.
- Cost of the Repair: A common rule of thumb is to consider replacement if the cost of a single repair is 40-50% of the cost of a new system.
- Frequency of Breakdowns: If you find yourself calling for repairs multiple times a year, the cumulative cost and inconvenience often make a new, reliable system a better choice.
- Energy Efficiency: Older heat pumps are significantly less efficient than modern models. A new high-efficiency unit can lead to substantial savings on your monthly utility bills, helping to offset the initial investment.
Our technicians will provide a clear and detailed diagnosis of your current system's health and present all available options, allowing you to make an informed decision without pressure.

I highly recommend this company for anyone needing AC repair or maintenance. I'll definitely be calling them again for any future needs!








I had the pleasure of experiencing outstanding service and professionalism from Ruben, and I am beyond impressed. From the moment I first contacted them, by phone and follow up communication via email for my quotes. The attention to detail and commitment to excellence were evident.
Ruben, was incredibly responsive, addressing all my inquiries promptly and with clear, thorough explanations. Their dedication to understanding and meeting my needs was remarkable.
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.
