Common Furnace Issues We Service

High-performance furnaces can present unique challenges that require a deep understanding of their advanced systems. Our team in Diamond Bar has extensive experience diagnosing and repairing the full spectrum of issues affecting premium series units, from minor sensor malfunctions to complex component failures.

Malfunctioning Variable-Speed Blower Motor: Unlike single-speed motors, a variable-speed blower adjusts its output for optimal efficiency and comfort. If you notice weak airflow, no air coming from the vents despite the furnace running, or loud humming and grinding noises, the complex motor or its control module may be at fault. We use advanced diagnostics to test the motor and its electronic controls to pinpoint the exact point of failure.

Ignition System Failure: furnaces utilize sophisticated ignition systems, such as hot surface ignitors or intermittent pilots, for reliable and efficient startups. If your furnace clicks but fails to ignite, or if it starts and then shuts down shortly after (short cycling), it often points to a problem with the ignitor, flame sensor, or control board logic. We can accurately identify the faulty component and replace it with a part that meets manufacturer specifications.

Communicating Thermostat and Control Board Errors: These premium furnaces often pair with a communicating thermostat that shares detailed diagnostic information with the furnace control board. If there's a breakdown in this communication, you might experience erratic heating, incorrect temperature readings, or a complete system shutdown. We have the diagnostic tools to interpret the specific error codes your system displays, allowing us to address issues with the control board, wiring, or thermostat itself.

Multi-Stage Burner Problems: A key feature of furnaces is their ability to operate at different heating capacities (stages) for enhanced efficiency. If your home isn't heating evenly or the furnace seems to be running constantly without reaching the set temperature, the system may be stuck in a low-fire stage due to a faulty gas valve or sensor. Our technicians can test and calibrate the multi-stage system to restore its full heating capability.

Pressure Switch and Sensor Faults: Your furnace relies on a network of sensors to ensure safe and efficient operation, monitoring everything from airflow and exhaust venting to internal temperatures. A single faulty pressure switch or limit sensor can prevent the furnace from starting up or cause it to shut down unexpectedly. We meticulously test each sensor in the safety circuit to ensure proper function.

Our Furnace Repair Process

We believe in a transparent and thorough approach to furnace repair, ensuring you are informed and confident at every step. Our process is designed to accurately diagnose the problem and provide a lasting solution that restores your system’s high-performance capabilities.

Comprehensive System Diagnosis: Our process begins with a detailed diagnostic inspection. A technician will connect specialized tools to your furnace’s control board to retrieve error codes and run system tests. We go beyond the obvious symptoms to assess the entire system, including the blower, ignition assembly, gas valve, sensors, and electrical components, to identify the precise root cause of the failure.
Clear Explanation and Upfront Options: Once the diagnosis is complete, our technician will explain the findings to you in clear, understandable terms. We will show you the faulty component, explain why it failed, and present you with a detailed, upfront quote for the recommended repair. We ensure you have all the information needed to make an informed decision about your home’s heating system.
Precision Repair with High-Quality Parts: Upon your approval, our technician will proceed with the repair using parts that meet or exceed the original manufacturer's specifications for furnaces. We carry a wide inventory of common components to ensure we can complete most repairs in a single visit. Our workmanship is meticulous, ensuring every connection is secure and every component is installed correctly for safe and reliable operation.
System Calibration and Performance Testing: A repair is not complete until we verify the system is running perfectly. After replacing the faulty part, we will calibrate the furnace, test the heating cycle, measure gas pressure, and check thermostat communication. This final step ensures your furnace is operating not just safely, but at the peak efficiency and comfort levels it was designed to deliver.

Ruben and team at Piggies Air Conditioning were amazing to work with. They got our AC installed and our old unit removed within 1 day and at a great price. We highly recommend Piggies Air Conditioning!

Ruben from Piggies went above and beyond when he came to provide us with a quote for doing some duct work. He was also able to identify the underlying problem as to why we have been having a major issue with our heat in our office suite. He took photos, explained the issue, what he could and could not do, and what to communicate to our property owner. He spent far longer answering questions and finding the source of an issue that wasn't even the reason why he was onsite. EXCELLENT
CUSTOMER SERVICE!

First of all I NEVER do reviews or rate any company or product. But, Piggies Air Conditioning did an amazing job at a GREAT price! I always get at least 3 estimates, and in this particular situation, I had at least 5. These guys were the most reasonable by several thousand dollars, with BETTER equipment that the others! Our ac and heat package is at least a 17 seer system, which is top of the line! I've been in the construction business my entire life, and dealt with many companies from all the trades. It really doesn't get any better than Piggies! This company and its personnel were on time, and courteous, which is hard to come by these days. Ruben, Luis were very professional, and I was in constant contact with them throughout the job. The Daikin product is one of the best in the world! I'm giving Piggies two thumbs way up!

Charlene B.

Ruben was very responsive and quick to assess. Gave really great advice and cares about the service he provides. Looking forward to using Piggies for HVAC issues and maintenance.

Tran L.

Overall great job replacing our antiquated AC unit. The evaluation and detail is a big deal to us. Rueben explained all the techincal aspects and gave us great
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.

Therese F.

I am a realtor in Los Angeles, and while we were getting ready to sell my clients home in Pasadena, an inspector from another company backed into my clients air conditioner. I was referred to Piggies AC by another trusted client so I called them. I talked to Ruben, he answered the phone right away, answered some of my initial questions, and was able to get me an appointment just two days later. On site Ruben was there on time, was extremely knowledgeable, And told us the best course of action to get the AC unit back in good working order. A day or two later he sent us an invoice and his prices were very reasonable. I am happy, Client is happy, thank you Ruben!

Woody M.

Leaving a 5-star review just after the initial inspection because I was blown away by Ruben's professionalism.
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.
