Common Furnace Problems We Expertly Resolve
Furnaces are complex systems, and over time, various components can wear out or malfunction. Our experienced technicians have seen it all and are equipped to handle a wide range of issues. If you’re experiencing any of the following problems, it’s time to call a professional.
Furnace Fails to Turn On
This is one of the most common and frustrating furnace issues. The cause could be as simple as a tripped circuit breaker or an incorrect thermostat setting. However, it can also point to more complex problems like a faulty ignition system, a malfunctioning transformer, or an issue with the furnace’s control board. Our technicians will systematically check all potential causes to identify and fix the exact problem.
Inadequate or No Heat Production
If your furnace is running but the air coming from the vents is cool or lukewarm, it defeats the purpose of your heating system. This issue is often linked to dirty filters that restrict airflow, a problem with the pilot light or electronic ignition, or a malfunction in the gas valve. We will thoroughly inspect your system to ensure it’s producing the powerful, consistent heat you need.
Strange Noises During Operation
Your furnace should operate with a gentle, consistent hum. Loud or unusual noises are clear indicators of an underlying problem.
- Banging or Popping: Often caused by dirty burners leading to delayed ignition or expanding/contracting air ducts.
- Squealing or Whining: Typically points to a problem with the blower motor, a loose belt, or issues with the motor bearings.
- Rattling or Vibrating: Could be a loose panel, debris in the system, or a sign of a more serious mechanical issue.
Ignoring these sounds can lead to more significant and costly damage. At Piggies Air Conditioning, we can quickly diagnose the source of the noise and perform the necessary repairs.
Frequent or Short Cycling
Does your furnace turn on and off every few minutes? This "short cycling" is not only inefficient, driving up your energy bills, but it also puts excessive strain on the system's components. Common culprits include a clogged air filter, a malfunctioning thermostat, or an oversized furnace for your home's needs. We'll identify the reason for the rapid cycling and provide a lasting solution.
Pilot Light or Ignition Control Issues
For older gas furnaces, a pilot light that won’t stay lit or burns yellow instead of a crisp blue is a sign of trouble. It could indicate a faulty thermocouple or a dirty pilot assembly. For modern furnaces with electronic ignitions, a failure in the hot surface ignitor or intermittent pilot system will prevent the furnace from starting. These issues can involve gas and electricity, making professional repair essential for your safety.
Our Comprehensive Furnace Repair Process
We believe in a transparent and thorough approach to every repair job. When you entrust us with your furnace, you can expect a seamless and professional experience from start to finish.

We don’t just look for the obvious symptom; we dig deeper to find the root cause. This includes checking the thermostat, electrical connections, ignition system, safety controls, and mechanical components to ensure an accurate diagnosis.
Clear Communication and Transparent Options
Once we have identified the problem, we take the time to explain our findings to you in clear, easy-to-understand terms. We will outline the issue, discuss the best repair options available, and answer any questions you may have. You will receive a detailed and straightforward quote before any work begins, ensuring you are fully informed and in control of the decision-making process.

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.
