Common Furnace Problems We Solve
Furnaces often show clear signs of distress before they fail completely. Recognizing these symptoms can help you know when it’s time to call for a professional diagnosis. If you notice any of the following issues, it’s a strong indication that your furnace needs immediate attention.
- No Heat or Insufficient Warm Air: The most obvious sign of a problem. This could be caused by anything from a faulty thermostat or a tripped circuit breaker to a malfunctioning pilot light or a failed blower motor.
- Strange Noises: Your furnace should operate relatively quietly. Loud banging, rattling, squealing, or grinding sounds are not normal. These noises often point to mechanical issues, such as a loose component, a problem with the blower motor, or an unbalanced fan.
- Pilot Light or Ignition Issues: For gas furnaces, a pilot light that won't stay lit or an electronic igniter that clicks but fails to light the burners is a common failure point. This can be caused by a faulty thermocouple, a clogged pilot orifice, or an electrical issue with the igniter.
- Frequent Cycling (Short-Cycling): If your furnace turns on and off in rapid succession without completing a full heating cycle, it's known as short-cycling. This is often caused by a clogged air filter, an oversized furnace, or a malfunctioning thermostat, and it puts excessive strain on the system.
- The Blower Motor Runs Constantly: The blower fan should only run during a heating cycle. If it never shuts off, you may have a faulty limit switch or a wiring problem that requires professional inspection.
- Unusual Odors: A faint burning smell when you first turn on the heat for the season can be normal as dust burns off. However, a persistent burning smell, the odor of melting plastic, or the distinct scent of gas are serious warning signs that require you to shut down the system and call for immediate service.
Our Comprehensive Furnace Repair Process
We believe in a thorough and transparent approach to every repair. Our goal is not just to fix the immediate problem but to ensure your entire system is safe and reliable.
- Thorough System Diagnosis: Our certified technician will arrive and conduct a comprehensive diagnostic inspection of your furnace. This involves more than a quick look; we use specialized tools to test electrical components, check safety controls, inspect the heat exchanger for cracks, and analyze system performance to accurately identify the root cause of the failure.
- Clear Explanation and Upfront Estimate: Once the problem is identified, we will explain the issue to you in clear, understandable terms. We’ll show you what we found and present you with a detailed estimate for the necessary repairs. We ensure you have all the information you need to make an informed decision before any work begins.
- Professional and Efficient Repair: With your approval, our technician will proceed with the repair using high-quality replacement parts and industry-best practices. We work meticulously to restore your furnace to optimal working condition, respecting your home and cleaning up our work area upon completion.
- Final System Testing: After the repair is complete, we don’t just pack up and leave. We test the entire system, running it through a full heating cycle to verify that the repair was successful and that your furnace is operating safely and efficiently.
Repairing or Replacing Your Furnace: An Honest Assessment
A common question from South Pasadena homeowners is whether to repair an older furnace or invest in a new one. The answer depends on several factors, including the age of your unit, the cost of the repair, and your furnace's overall efficiency and repair history.
Generally, if your furnace is over 15-20 years old and requires a major, costly repair—such as a new heat exchanger or blower motor—replacement may be the more financially sound option in the long run. A new, high-efficiency furnace can significantly lower your energy bills, providing a return on your investment over time. However, if your furnace is younger and the required repair is relatively minor, a professional repair is often the most cost-effective choice to extend its lifespan. We 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.
