Signs Your Furnace Needs Professional Attention

Catching furnace issues early can prevent extensive and costly repairs. If you notice any of the following signs, it’s time to schedule a professional inspection with Piggies Air Conditioning.

Unusual Noises

Furnaces should operate with a consistent, low hum. Banging, scraping, squealing, or popping sounds often point to mechanical problems such as loose components, worn-out belts, or blower motor issues.

Insufficient or No Heat

A furnace running but producing cool or lukewarm air indicates potential problems with the burner, pilot light, or heat exchanger.

Frequent Cycling

If your furnace turns on and off more often than usual, it could be short cycling caused by a clogged filter, faulty thermostat, or an oversized unit, which strains your system and increases energy costs.

Higher-Than-Normal Energy Bills

A sudden spike in heating bills often signals that your furnace is working harder than necessary due to inefficiency or a failing component.

Yellow Pilot Light

For gas furnaces, a steady blue flame is normal. A flickering or yellow flame can indicate ventilation issues or a carbon monoxide leak, requiring immediate professional attention.

Poor Air Quality

Increased dust, soot, or dry air may suggest a malfunctioning furnace, problems with the filtration system, or a cracked heat exchanger circulating contaminants through your home.

Our Comprehensive Diagnostic and Repair Process

At Piggies Air Conditioning, we don’t rely on guesswork. Our certified technicians perform a thorough diagnostic evaluation to pinpoint the root cause of your furnace issues.

Initial System Inspection

We examine the entire heating system—from the thermostat to the furnace unit itself—for visible signs of wear, damage, or loose connections.

Safety Control Check

Your safety is our priority. We test all safety controls, including limit switches and flame sensors, to ensure proper functioning and protection for your home.

Electrical and Mechanical Testing

All electrical components such as capacitors, relays, and blower motors are tested, while belts and bearings are inspected for wear that could cause noise or inefficiency.

Ignition and Burner Assembly Analysis

We examine the pilot light or electronic ignition system, cleaning and adjusting components as needed to ensure safe, reliable operation.

Heat Exchanger Inspection

A cracked heat exchanger is a serious hazard. We conduct a detailed inspection to guarantee its integrity and prevent carbon monoxide leaks.

Airflow and Ductwork Assessment

Filters and ductwork are checked for obstructions to ensure proper airflow and reduce system strain.

After diagnosing the issue, we explain the problem clearly and outline a transparent repair plan, empowering you to make an informed decision for your home.

Customer Testimonials

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!

Heather S.

Piggies AC is hands down my favorite HVAC contractor. Ruben truly cares about true home comfort. If I could leave 10 stars I would. Thanks Piggies

I recently had my air conditioning unit serviced by Ruben, and I couldn't be more impressed. From start to finish, the experience was smooth and professional. He arrived on time, was incredibly knowledgeable, and explained the issue in a way that was easy to understand. He worked efficiently, resolved the problem quickly, and made sure everything was functioning perfectly before leaving.
I highly recommend this company for anyone needing AC repair or maintenance. I'll definitely be calling them again for any future needs!

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!

I recently had the pleasure of working with Piggies Air Conditioning, and I can't recommend them enough! From the moment I contacted Ruben, their team displayed an impressive level of knowledge and experience in the field. They answered all of my MANY questions with ease and friendliness and provided insights that really helped me understand my options and the scope of work as a whole. The communication throughout the process was fantastic. They kept me informed every step of the way, which was especially reassuring as a new homeowner navigating this kind of installation for the first time. I felt confident in their expertise and reccomendations they presented for our new HVAC sytems. When it came time for the installation, I was blown away by how efficient and professional the team was. They did a fantastic job with the installation itself and left the area spotless afterward. It was clear they respected our home as if it were their own, which is surprisingly rare in certain service fields, and greatly appreciated. Overall, my experience with Piggies Air Conditioning was excellent, and I would gladly recommend them to anyone in need of HVAC services.

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!

Professionalism & Quality work at its utmost best!
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.

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.
