Signs Your Heating System Needs Professional Repair
Ignoring the early warning signs of a failing heater can lead to more extensive and costly damage. If you notice any of the following issues, it’s a clear indication that your system requires professional attention.
- No Heat or Insufficient Warm Air: The most obvious sign of a problem. This could stem from a faulty thermostat, a pilot light issue in a gas furnace, or a problem with the blower motor.
- Strange Noises: Your heating system should operate with minimal noise. Loud banging, grinding, squealing, or rattling sounds often point to mechanical problems, such as a failing motor, a loose component, or issues with the blower assembly.
- Unusual Odors: A burning smell could indicate overheating electrical components or dust burning off, but a persistent odor requires immediate inspection. The smell of gas or rotten eggs is a serious safety hazard that requires you to shut off your system and call for emergency service right away.
- Frequent or Short Cycling: If your heater turns on and off more frequently than usual without reaching the set temperature, it’s known as short cycling. This common issue can be caused by a clogged filter, a malfunctioning thermostat, or an oversized system, and it puts excessive wear on components.
- The Blower is Always Running: A blower fan that never shuts off could be due to a faulty fan limit switch or an issue with your thermostat settings.
- Sudden Spike in Energy Bills: A heating system that is struggling to perform will consume more energy. If your utility bills have increased without a change in your usage habits, your heater is likely losing efficiency and needs a diagnostic check.
Comprehensive Heating Repair for Altadena Homes
Our certified technicians are equipped to handle a wide range of heating systems commonly found in Altadena homes. We don’t just treat the symptoms; we perform a thorough diagnosis to identify the root cause of the problem, ensuring a durable and effective repair.
Furnace Repair
Whether you have a gas or electric furnace, our team has the expertise to resolve any issue. We routinely handle:
- Ignitor and Pilot Light Failures: A common reason for a furnace not producing heat.
- Blower Motor Repair and Replacement: Addressing issues that prevent warm air from circulating through your home.
- Faulty Thermostats: Repairing or replacing thermostats that cause temperature inaccuracies or system cycling problems.
- Limit Switch Malfunctions: Correcting problems with safety components that can cause your system to shut down unexpectedly.
- Cracked Heat Exchanger Inspection: A cracked heat exchanger can leak carbon monoxide, and we treat this as a critical safety inspection.
Heat Pump Repair
Heat pumps provide both heating and cooling, and their dual function means they work year-round. Common heat pump repairs we address include:
- Refrigerant Leaks: Low refrigerant levels can severely impact heating performance and damage the compressor.
- Compressor Issues: The compressor is the heart of the heat pump, and we can diagnose and repair issues related to its function.
- Defrost Cycle Problems: If your heat pump is stuck in the defrost cycle or freezes over, it cannot heat your home effectively.
- Reversing Valve Malfunctions: A stuck reversing valve can leave your system stuck in either heating or cooling mode, preventing it from switching over as needed.
Our Diagnostic and Repair Process: What to Expect
We believe in a transparent and customer-focused approach. When you call us for heating repair in Altadena, you can expect a seamless and professional experience.
- Thorough System Diagnosis: Our technician will arrive on time, listen to your concerns, and conduct a comprehensive diagnostic inspection of your entire heating system to accurately pinpoint the problem.
- Clear Explanation and Upfront Quote: Once the issue is identified, we will explain the problem to you in clear, understandable terms. We will outline the best repair options and provide a detailed, upfront quote before any work begins.
- Expert Repair with Quality Parts: With your approval, our certified technician will perform the repair using high-quality, durable parts to ensure a lasting solution. We treat your home with respect, maintaining a clean and organized workspace.
- Final System Testing: After the repair is complete, we don’t just leave. We test the system thoroughly to ensure it is operating safely, efficiently, and to your complete satisfaction.
Is It Time to Repair or Replace Your Heater?
This is a common question for homeowners facing a significant repair. While we always aim to provide a cost-effective repair, sometimes a replacement is the smarter long-term investment. We recommend considering a replacement if:
- Your System is Over 15 Years Old: Older systems are less efficient and more prone to breakdowns.
- The Cost of Repair is High: If a repair costs 40-50% of a new system, replacement is often more economical.
- You Experience Frequent Breakdowns: Constant repairs indicate that the system is nearing the end of its lifespan.
- Your Energy Bills Are Rising: A new, high-efficiency system can provide significant savings on your monthly utility costs.
Our technicians can provide an honest assessment of your system’s condition and help you make an informed decision that best suits your home and budget.
When your heating system lets you down, you need a team you can trust to restore your comfort quickly and professionally. Contact us today to schedule your heating repair service in Altadena.

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.
