Common Furnace Problems We Solve
A furnace will often display warning signs before it breaks down completely. Recognizing these signals can help you seek timely repairs and avoid a mid-winter emergency. If you notice any of the following issues with your heating system, it’s time to call a professional.
No Heat or Inadequate Heating
The most obvious sign of a problem is a furnace that won't turn on or fails to produce enough warm air to heat your home. This can be caused by a range of issues, including a faulty thermostat, a malfunctioning pilot light or ignition system, or a problem with the gas supply. Our technicians can quickly trace the source of the failure and implement the correct fix.
Unusual and Loud Noises
Your furnace should operate with a relatively consistent, low-level hum. If you suddenly hear loud banging, rattling, scraping, or high-pitched squealing, it’s an indication of a mechanical problem. Banging could point to an issue with your ducts or a delayed ignition, while scraping or grinding often signifies a problem with the blower wheel or motor bearings. Ignoring these sounds can lead to more severe and costly damage.
Frequent or Short Cycling
Does your furnace turn on and off every few minutes? This is known as short cycling. It not only prevents your home from heating evenly but also puts excessive strain on the system’s components, leading to premature wear and tear and higher energy bills. Common causes include a clogged filter, an improperly sized furnace, or a malfunctioning thermostat.
Yellow or Flickering Pilot Light
If you have an older furnace with a pilot light, it should always be a steady, crisp blue flame. A pilot light that is yellow, orange, or flickering is a major warning sign. This often indicates a dirty orifice or a ventilation problem, which could lead to incomplete combustion and the production of dangerous carbon monoxide gas. This is a serious safety hazard that requires immediate professional attention.
Strange Odors
When you first turn on your furnace for the season, a faint dusty or burning smell is normal as it burns off accumulated dust. However, if you detect a strong smell of burning plastic, melting wires, or a persistent odor that resembles rotten eggs (a sign of a potential gas leak), you must act immediately. Turn off your furnace and contact a professional service for an emergency inspection.
Our Detailed Furnace Diagnostic and Repair Process
We believe in a transparent and thorough approach to furnace repair. Our goal is to provide a lasting solution, not a temporary patch. When you entrust us with your heating system, you can expect a methodical process designed for accuracy and safety.
- Comprehensive System Inspection: Our service begins with a complete diagnostic evaluation of your entire heating system. A skilled technician will arrive at your Altadena home equipped with the tools and knowledge to accurately identify the root cause of the problem. This includes inspecting the thermostat for proper calibration, checking the air filter for blockages, examining the electronic ignition or pilot light, testing the blower motor and fan components, and verifying the integrity of all safety controls.
- Clear Communication and Honest Recommendations: Once the problem has been pinpointed, our technician will explain the findings to you in clear, understandable terms. We avoid confusing technical jargon and ensure you understand exactly what is wrong with your furnace and what is required to fix it. We will present the best course of action for the repair, outlining the necessary steps and the rationale behind them so you can make an informed decision.
- Precision Repair with High-Quality Parts: With your approval, our technician will proceed with the repair. We use only high-quality, durable replacement parts to ensure the longevity and reliability of our work. Whether the job requires replacing a faulty ignitor, cleaning a flame sensor, installing a new blower motor, or repairing the main control board, we perform every task with meticulous attention to detail and adherence to the highest industry standards.
- Final Testing and Safety Verification: After the repair is complete, our job isn't finished. We conduct a full system test to confirm that your furnace is operating at peak performance and efficiency. Most importantly, we perform a comprehensive safety check. This includes verifying secure electrical connections, checking for proper ventilation, and testing for any gas leaks or carbon monoxide risks to ensure your system is not only warm but unequivocally safe for your family.

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.

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.
