Signs Your Heat Pump Needs Professional Attention
Heat pumps are complex systems, and while they are built for durability, they can exhibit clear warning signs when a component is failing. Ignoring these symptoms can lead to more significant damage and costlier repairs down the line. If you notice any of the following issues, it’s time to schedule a professional inspection.
- Inadequate Heating or Cooling: The most obvious sign of a problem is when your system struggles to reach the temperature set on your thermostat. If the air coming from your vents is lukewarm or weak, it indicates a potential issue with the compressor, refrigerant levels, or airflow.
- Unusual Noises: Your heat pump should operate with a relatively low hum. Loud or strange noises like grinding, squealing, hissing, or rattling are clear indicators of mechanical problems. These sounds can point to issues with the fan motor, loose components, or a failing compressor.
- Constant or Frequent Cycling: A heat pump that turns on and off too frequently, known as short cycling, is not operating efficiently. This could be caused by a faulty thermostat, a clogged filter, or an oversized system, and it puts excessive wear on the unit’s components.
- Ice Buildup on the Outdoor Unit: While a thin layer of frost can be normal in winter, a significant accumulation of ice, especially on the outdoor coils, signals a problem with the defrost cycle. This can be caused by low refrigerant, a malfunctioning defrost control board, or poor airflow.
- Sudden Spike in Energy Bills: If your utility bills have unexpectedly increased without a change in your usage habits, your heat pump may be the culprit. A struggling system has to work much harder to heat or cool your home, consuming more energy in the process.
Our Comprehensive Diagnostic and Repair Process
We believe in a methodical approach to heat pump repair that guarantees we identify the root cause of the problem, not just the symptoms. Our process is designed for accuracy, transparency, and efficiency, ensuring you receive a repair that lasts.
First, our certified technicians conduct a thorough diagnostic assessment. This involves a complete inspection of both the indoor and outdoor units. We examine all critical components, including the compressor, fan motors, reversing valve, coils, and electrical connections. We use advanced diagnostic tools to check refrigerant pressure, test electrical circuits, and measure airflow, leaving no stone unturned to pinpoint the exact source of the malfunction.
Once we have identified the problem, we explain our findings to you in clear, easy-to-understand terms. We outline the necessary repairs, discuss the parts required, and provide a straightforward estimate before any work begins. This transparency ensures you can make an informed decision about your home’s comfort system without any surprises.
With your approval, our technician proceeds with the expert repair. We use high-quality, durable replacement parts to ensure the longevity of our work. Whether the job requires recharging the refrigerant, replacing a faulty fan motor, repairing the defrost control board, or fixing a complex electrical issue, our team has the skill and experience to complete the job correctly and efficiently.
Finally, after the repair is complete, we don’t just pack up and leave. We perform a full system test to verify that the heat pump is operating at its optimal efficiency. We check temperature outputs, cycle times, and overall performance to ensure your system is ready to keep your Altadena home comfortable year-round.
Is it Time to Repair or Replace Your Heat Pump?
A common question homeowners face is whether to invest in a repair or consider a full system replacement. This decision often depends on a few key factors. If your heat pump is relatively new (less than 10 years old) and the repair cost is reasonable, a repair is typically the most cost-effective choice. However, if your system is approaching the end of its average 10-15 year lifespan, has required multiple repairs recently, or needs a major component replacement like a compressor, it may be more economical in the long run to invest in a new, high-efficiency unit. A new system can offer significantly lower energy bills and improved reliability, offsetting the initial investment over time. We can provide an honest assessment to help you weigh the costs and benefits, ensuring you make the best decision for your home and budget.

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.
