Ways to Tell That You Need Professional Duct Sealing in Marana
The integrity of the air ducts in your house is vital to maintaining an efficient and effective air conditioner and heater. If you have ducts with breaks, holes, or leaks across them, or spots with poor joints and loose connections, it will place extra strain on the heater/AC and reduce comfort in your home. Duct leaks will also have a negative effect on the quality of your indoor air. To solve these problems, you need to call for professional air duct sealers who can close up the leaks in the ductwork and restore its airtightness.
Since ducts are mostly hidden from sight, you’ll need guidelines for how to tell that they may have leaks. Below we’ll list some of the common signs that can warn about breaches in your home’s ductwork (and which may also point to other problems in your HVAC system). If you notice any of these signs, call Goettl Good Guys Air Conditioning and ask about our duct sealing for Marana, AZ homes. We are available 24/7 whenever you need quality service for your home comfort.
Warning signs of leaky ducts
- Unusual smells from the vents: When ductwork develops breaks or holes, dust and other debris will start to enter the ventilation system. Because ducts run through closed-off areas of a house, you will often notice a musty taint to the air coming from the vents. If dust starts to enter the heater or air conditioner, you may notice an acrid smell.
- Changes in air temperature or humidity: Air leaks will cause heat to escape or enter the ducts, depending on the outside temperature. This will lead to a drop in heating or cooling capability. It will also lead to an increase in humidity from the moister outside air. If your HVAC system is struggling to reach the temperature you desire, and you feel muggy air in some of the rooms, you may have damaged ducts.
- Rise in utility bills: Leaks will force an air conditioner and heater to work harder to compensate for the loss of air pressure, and you will consequently see a jump in your utility bills that you can’t otherwise explain. Although other HVAC troubles could account for this problem, you will still need a professional to investigate and find the source.
Do not hesitate when it comes to investigating any of these above signs. You are not only risking higher bills and an HVAC system rapidly wearing down, but you are risking a dramatic and unhealthy drop in indoor air quality.
If duct sealing in Marana, AZ will solve the problem, you can count on our skilled team to handle it.
Call on Goettl Good Guys Air Conditioning, any time of the day or night, when you need professional assistance for your heating, air conditioning, or ventilation system.

After toughing it out for a night I scheduled a service check with Goettl. Jorge came out and I'm so thankful that he was the one to show up. I was greeted at the door with a gift for my doggo and a new flashlight. Jorge took a look at my system and he knew his stuff. Optimal operating temperatures, pressures and the whole works. He took the time to explain it to me, show me the failed parts and even give me a list of options. With those he gave me realistic expectations at each price point.
He was able to work his magic and get my system back online and my house cool again. This isn't my first time calling on goettl and it won't be my last.





I’ll be canceling my home warranty and working directly with Goettl Air Conditioning & Plumbing from now on. Their reliability and customer care are unmatched. I’m very grateful for Jesus’s honesty and dedication highly recommend!

He explained, while he saw no immediate problems. what we might expect going forward, given the furnace's age and condition. After I asked about major component vs. whole-unit replacement, he provided a thorough explanation, and pricing, of options for us to consider.
Very good experience with Jef! Highly recommend!



Also, thanks to the other team members involved such as the appointment scheduler and Justin. Both were very professional & efficient with my slightly demanding request.

My issue is that service was for the morning and ended up at 3pm. This has been a problem for multiple service/maintenance appointments to include two cancelations. As a working professional, timing is very critical in my daily scheduling.

He took the time to walk me through everything about our unit and answered all my questions clearly. I was very impressed with his professionalism, knowledge, and attention to detail.
Thank you, Jeremy, for your excellent service!






His experience led us to a solution for our pipes, which saved us thousands and thousands of dollars.
He’s a good man to have on your side



Edit: I was contacted by the branch manager and she accepted full responsibility and was very upfront. They made up for it in kind and I appreciate them being upfront and willing to make the situation right. Their customer service is top notch!


The service was perfect. The technician Julian Bray was pleasant, knowledgeable and completed the install quickly. The area was left cleaner than when he arrived.


The leads Nick & Brian were knowledgeable and covered our floors to protect them. Their crew included Kevin & Ricky who were also kind and respectful.

As always they came thru and did an excellent job Damian Palazeulos was very meticulous and skilled.



Installer Tech Ardian and his assistant arrived on schedule this morning and have completed the job that needed to be done orderly and neatly. Thanks everyone.


Jesus was are tec came in check everything let me know what would need to be done or taken care of came in respectfully with a great attitude
Highly exceptional service we definitely will be requesting him if possible great experience today

If there was a 6th star, he’d be getting it!








Thank you Preston






Professional, knowledgeable and efficient. Very polite and courteous
Also installed surge protectors on the the condensers






We’ve been Goettl customers for years and have always appreciated their service, but Kevin Edwards truly raised the bar. During his visit yesterday, Kevin showed outstanding attention to detail and technical expertise. He thoroughly inspected every part of our HVAC system, documenting his findings with photos and clearly explaining issues that had gone unnoticed through several previous service visits.
Kevin discovered that our HVAC system had been improperly installed when the home was built—something no other technician had identified. He explained how that flaw had created a chain of problems affecting the furnace, cooling system, and overall efficiency. Because the system uses an outdated refrigerant, repairs weren’t a viable long-term solution, and Kevin guided us toward a responsible upgrade plan.
While no homeowner wants to replace a system after only seven years, we’re grateful Kevin uncovered these hidden issues before they caused a catastrophic failure. His thoroughness, honesty, and professionalism turned a potential headache into peace of mind. Kevin is an exceptional representative of Goettl, and we recommend him without hesitation.












This past week our service technician was Andrew Morgan and he is such a friendly, knowledgeable, and skilled technician. He spent time making sure the job was done correctly and he explained it in terms that I could understand. Not only is our unit functioning even better than before, I also gained knowledge of how the system works.













I highly recommend Goettl as this is the second time l've used them in less than a year. (2 seperate issues)... and I highly recommend them..anytime and anyday.
They have exceeded to top any expectations I could have ever had with any company.


Jerry also noticed our water pressure was low after flushing toilet then trying to wash hands in bathroom sink which were so he suggested a new pressure regulator as we have had a new better water conditioning system installed. We now have the best water pressure even when using a shower and kitchen sink faucet at the same time. Also Jerry is a master plumber and we appreciate his knowledge and experience. Will definitely call Goettl again when a plumber is needed.

Darean Guerra today. He arrived on time and took the time to explain what he was going to do. He was very knowledgeable which helped me trust what he was doing. He left his work area clean. I am very pleased with his work.




Now we have a new flange, installed correctly, and ready for the new toilet!








The company is installing a tankless heater and the customer service is outstanding.
I recommend Geottl to all!

I definitely recommend Goettl for all your needs.


They made sure my carpet was covered and when they were all through they cleaned up perfectly
I would recommend your company to anyone looking to put in a new air conditioner.
Thank you so much for all you did for me.
Sincerely, June Jones

And I would highly recommend the company and the quality technicians like Jarod.
Jarod is the go to if you want excellent
Customer service and communication for any AC related issues. He is very knowledgeable, personable and trustworthy. I am grateful and satisfied.







They listened to my issue, were very through, checked for leaks, etc. I’ve lived in Lakeway for 30 years, used MANY local plumbers - but Goettl will definitely get all my business moving forward. HIGHLY recommend!
Ty, Wil & Adrian!

Everyone from the Goettl sales representative Christian, Tech / Advisor Josias recommended a HVAC A/C and Heating system replacement. Technicians team Veronica and her partner.
