What Is Involved in Duct Testing?
You may not be aware of how important your home’s network of ducts is. It’s responsible for bringing conditioned air from your heater and air conditioner into the rooms throughout your house, and it also circulates air through the intake vents and into the HVAC system. In order to do its job effectively, the ventilation system must remain in excellent condition with an airtight seal. If this seal develops leaks because of breaks, holes, corrosion, and loose connections, it will cause a plunge in air pressure that will severely affect your home’s comfort. It will also allow contamination to enter the ventilation system, and this will damage your indoor air quality.
Through duct testing you can find out about the integrity of your home’s ductwork. Professionals will come to your house and perform tests that will locate where your ducts have air leaks that are lowering efficiency and endangering your air. After duct testing is finished, the experts will know exactly what needs repairs and how to take care of those repairs.
For duct testing in Green Valley, AZ, call our indoor air quality specialists at Goettl Good Guys Air Conditioning. We have over 70 years of experience in caring for home comfort in Arizona.
Here’s what happens during duct testing
Duct testing involves sealing off an entire ventilation system and then pressurizing it in order to determine how airtight it is. The technicians determine how much air pressure is escaping from the ductwork and then trace down the locations so they can repair or seal them.
The first step in duct testing is to close off all the vents and registers into your home so that the only place air pressure can escape is through leaks along the ducts. A vacuum is attached to the ductwork near the HVAC unit and the whole ventilation system is put under pressure. Using a duct leak tester, the technicians learn how much pressure is escaping from the ventilation system, and this gives them a sense of the scope of the problem.
Once they have determined the total leakage in the ventilation system, the technicians move across the ducts with a pressure sensor to pinpoint the actual leaks and measure how much they air they are losing. Based on these findings, the technicians will recommend the work necessary to make the ductwork airtight once more. It can involve mastic sealing, metallic tape, or sometimes full duct replacements.

Duct testing is only the starting point for having airtight ducts. Once our specialists from Goettl Good Guys Air Conditioning have done the testing work, they can handle sealing and repairs, as well as duct cleaning that will ensure there is no contamination inside the ventilation system.

8/13/2024 Joe Benavides was very professional and kind. He worked diligently to unclog my drain in my master bath and cleaned up when he was finished. We got to chat while he worked and he is such an awesome individual! Another great experience from Goettl! 👍
Darrell Gonzales did a wonderful job and was very thorough! Very professional! Goettl hires great people give them a call! 📞 👏
Thank you Goettl you are my new "go to" service company.
Thanks Clayton and Goettl!
The following day, Jesus Gloria came out to inspect and service my HVAC. Again, I couldn't have asked for better service. Jesus was knowledgeable and took extra steps to ensure there were no further issues with my unit.
I wouldn't think twice about using Goettl Air Conditioning & Plumbing again!
We discussed options and agreed that a detailed lcleaning and sewing of all the ducts should eliminate this problem. He discussed financing and, and returned the following morning to make all the arrangements. He also advised us not to continuously run the A/C fans when the unit was not cooling, which seems to have helped with the humidity already, even though the duct work isn’t scheduled for a few days hence.
It was a pleasure to work with a knowledgeable A/C technician who could quickly isolate the cause of our problem and arrange a solution.
Alex was great with tune up and customer service!
Darean Guerra was awesome and fotnthe job done. Thank you!
Jesus Gloria – Goettl Plumbing & A/C
Jesus Gloria was many things: professional, proficient, polite, easy to talk to, and a true pleasure to have in my home.
He’s exactly the kind of professional you want handling your service needs. Jesus explained everything clearly and patiently—no jargon, no pressure. Let’s be honest, customers like me can be tough—we want 5-star service on a shoestring budget—but Jesus never missed a beat.
I made several changes during the project—adding services, canceling others—and Jesus handled it all without delay. No need to call the office or rework paperwork. He updated the order, adjusted pricing, and gave me a clear face-to-face explanation on the spot. All same day.
That’s outstanding service.
Goettl may not be the cheapest company out there, but they’re professionals who exceed expectations and hire top-tier people like Jesus. That’s why I’ll remain a loyal customer.
Jesus Gloria has my back—and I have his.
Thank you
UPDATE: one of the area service managers contacted me after my review and apologized and stated they wanted to rectify the situation and asked about my service quote from the company I decided to go with. He wanted to do the service at the same price and deduct the $428 I previously paid for diagnosis and throw in 2 years of maintenance. He told me he would talk with his boss and call me the next morning. He told me to email the other quote. I emailed him and he gave me his number. I never heard from him again! He never called me the next day as he said he would or replied to my email at all. So I am now adding that they do not keep their word either to this review! Horrible way to do business. Go with ASC heating and air where they know how to treat people with compassion, keep their word, give free second opinions, have veteran discounts, great customer service- Marsha is great and so is Ron 😊
Nathan came by promptly and inspected plumbing, and caught an issue under warranty for us!
Just an update, Andrew Morgan came and rejuvenated our system and did a wonderful job. His communication was clear and efficient.
07/23/25 Update. After getting the new larger duct to the master bedroom, it still wasn’t cooling properly. Goettl sends out another tech that actually knew what he was doing. Tech Billy McDermott found the problem. There was an opening on the back of the unit in attic that was blowing cold air into the attic. Once he sealed it up, low and behold the cold air is now coming into the living areas and the set temp is holding. I am leaving this rating at one star because after several techs coming out and telling us it was an airflow issue and we spent an extra $6K on insulation, come to find out none of the techs including a supervisor could find the problem. From now on if we have issues with HVAC, I want Billy to come to our house.
AC not working again since Friday night (8/8/25). I contacted Goettl as instructed, not satisfied with the response, still waiting for resolution and contact/communication from a manager.

7/2025 Update:
Goettl service technicians have returned to assist with some issues. Both Ian P. and Will M. we're both very professional it was believed issues were resolved. Dispatcher Betty was also able to hear my issues and arrange for a tech to arrive as quickly as possible.

Initial review 2/2025:
Jorge "George" was respectful and easy to communicate with. He listened and answered all our questions. Informed us of what and how Goettl could do with the 20+yr old system in our home, and gave us time and space make the best decision for us. So far very pleased with Goettl's professional conduct and standards.
Thanks you

They took the time to assess my system thoroughly, offered honest recommendations, and completed the work efficiently without cutting corners. My home is now noticeably more comfortable, and I feel confident knowing everything was handled by true professionals.

Jesus Gloria AC service review. He did a great job today and I would highly recommend him for any AC service needs. He was very knowledgeable and courteous. He helped add a surge protector on my outside unit for added protection. I look forward to working with him in the future.
Well, I had some plumbing issues at my residence, and I called "Goettl Plumbing." Great results, too 🤗.
My water wouldn't stay hot, and after contacting Justin at Goettl Plumbing, he sent out Frank, a service technician with over 20 years of plumbing experience. Frank spent a good bit of time studying/ evaluating my plumbing functions, consulted with an on-site Goettl supervisor, and determined my plumbing issues.
After they conferred those issues with Justin, a plan for resolution and payment was determined, and work started the next day.
Greg arrived that morning; accessed the work areas, determined the tools and equipment he needed, and got right to work.
By the end of the day, Greg had installed three (3) Replacement Single Handle Tub/Shower Valves, a Pressure reducing valve, and a Thermal expansion tank with vacuum breaker - - RESULTS: Hot Water 💧
In two days, I witnessed Super Communication, Super Teamwork, and some old-time "1990-1991" Professionalism ... thanks,
"GOETTL Air Conditioning & Plumbing" for A Job Well Done 👏🏼
After note. Cameron came back by a day later to check on readings he wasn't able to get on first appointment. I have high confidence in his work. I'm very likely to work with them again
Brayan and Marcos did an awesome job on the new ac installation. Installed with no issues and has been on ever since. Perfect time with summer coming up. Walked through and job was very clean and organized. Great work ethic. Great guys.
Update - our air conditioner went out today (10/26/23) and JEHAD showed up to repair the issue but the issue was bigger than expected. Tomorrow we will have a brand new system! Goettl is an EPIC firm that treats customers right. Thank you again JEHAD for going above and beyond.
Goettl is the epitome of what excellent customer service is! Our Drain King, DAREAN, addressed all of our questions and concerns and not only unclogged our drain but went above and beyond to show us our drains leading to the street were free and clear of any other issues. Thank you Darean and thank you Goettl for a great experience!
Update: great experience with Edgar Loredo who kept it real with us and was very transparent. I appreciate his honesty and recommendations. Will be requesting him as our technician in the future if we choose to use Goettl
