Is It Time to Replace Your Furnace?
Deciding between repairing your existing furnace or opting for a full replacement can be challenging. While some issues can be fixed, a new furnace is often the more economical and reliable long-term solution. Key indicators your furnace may need replacement include:
Age of the System
Most furnaces last 15–20 years. If your unit is approaching this range, it’s operating on borrowed time, and its efficiency is significantly lower than modern systems.
Rising Energy Bills
A sudden or steady increase in heating costs without a change in usage is a classic sign your furnace is losing efficiency and working harder to heat your home.
Frequent and Costly Repairs
If you call for repairs more than once a year, consider the “$5,000 Rule”: if your furnace’s age multiplied by the repair cost exceeds $5,000, replacement is usually the better financial choice.
Uneven Heating
Rooms that stay cold while others are warm indicate your furnace may no longer distribute heat effectively.
Strange Noises or Odors
Loud banging, rattling, or humming sounds can signal mechanical problems. Unusual smells could indicate issues with the burner or heat exchanger.
Visible Signs of Wear
Rust, cracks, or corrosion on the furnace are clear signs of deterioration that can compromise performance and safety.

CUSTOMER SERVICE!




I highly recommend this company for anyone needing AC repair or maintenance. I'll definitely be calling them again for any future needs!








I had the pleasure of experiencing outstanding service and professionalism from Ruben, and I am beyond impressed. From the moment I first contacted them, by phone and follow up communication via email for my quotes. The attention to detail and commitment to excellence were evident.
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.
