Is Your Ductwork Working Against You? 

Leaky ducts pull hot, humid attic air into your home every time the AC runs. These are the signs most San Antonio homeowners overlook for years.

  • Dust builds up fast no matter how often you clean 
  • Visible dirt or dark staining around supply registers 
  • Certain rooms are always warmer or harder to cool 
  • High energy bills even with a functioning AC system 
  • Musty or stale odors when the system kicks on 
  • You replaced your AC but the comfort problems stayed 
  • Allergy or asthma symptoms that will not let up at home

Let Goettl Take Care Of It

We don’t just vacuum your ducts and move on. We find out why they’re dirty and then we fix it.

Duct Cleaning 

We clean every supply and return line in your San Antonio home and document what we find. If your ducts are excessively dirty, there’s usually a leak problem behind it.

$499 duct cleaning

Duct Sealing 

Duct tape fails in San Antonio attic heat and humidity. We use a permanent liquid sealant that bonds from the inside so the repair lasts for good.

Free duct evaluation

Duct Replacement

Aging or undersized ductwork can’t keep up no matter how good your system is. We calculate the right size, replace the system, and balance airflow room by room.

Free estimate

Attic Insulation 

Sealing ducts without insulating is only half the fix. We pair duct work with proper insulation so South Texas heat and humidity stay out and your system runs as efficiently as possible.

Repairs were done the same afternoon I called. Christian was very concerned that we knew exactly where the problems were how he could repair. I will give him a 10 out of 10!

We were very impressed with the Goettl technician that was assigned to check our HVAC. Robert was thorough in checking our HVAC. He explained everything in detail as to what he did and what additional repairs that were needed. He did not pressure us for the additional repairs, plus recommended several options that we could look at. I highly recommend his service.

Alex Nelson was very honest and up front with me... He offered me options plans what I can do.. He didn't pressure me on just selling parts or replacing the whole unit... At the end of the day we decided to change out the unit. I glad I called Goettl

We woke up to no hot water this morning! Goettl’s was great scheduling Deonte Wilson to come out and help us. Deonte is a knowledgeable, capable & respectful young man and was able to resolve the problem within a half an hour. He kept us informed along the way too. I recommend Goettls plumbing and Deonte Wilson.

the level of care given by this company is top of the line! our ac went out sunday night & another company could get us seen thursday, which wasn’t going to be helpful with a 9mo & 3yo. google sent a form and then i wasn’t instantly in communication with a person. by midnight i was scheduled for next day service. before my scheduled time, betty called to see if i was available for an earlier time, ABSOLUTELY! our tech alex nelson was here in 45 minutes. he was able to quickly assess our issue and had everything back to working order by the next hour. had awesome recommendations & explained things thoroughly to my family, while entertaining all the kid questions!

Goettl came through in the clutch (on a Sunday!) when our AC went out. Their technician Robert Rodriguez had the parts on hand to get our system blowing cold air again. He was very knowledgeable and took the time to explain the work/repairs that he needed to perform. All for a reasonable, fair price. Will be calling them again for our HVAC maintenance needs as they arise in the future.

Darean came to diagnose an issue with our shower drainage, and was able to fairly easily identify the issue. He was kind and friendly while working, and even though the fix was one we would rather avoid, he was kind in giving us the news. He was also very helpful and made sure to explain everything very thoroughly.

Dylan came to my house to make sure my AC system was up to par. It was a great experience and he made us feel taken cared of. I would recommend Dylan and will be requesting him for future visits. We can’t have any animals in our home because my 3 year old son has asthma and Dylan was nice enough to give my son a stuff animal dog and a flashlight. Two things my son loves. Thank you Dylan for the awesome experience and gift for my son.

Our experience with Juan Gil was outstanding. He came to our home after regular business hours and went above and beyond what we expected. Not only did he clear our clogged kitchen sink, he also took the initiative to scope our sewer line and even identified a leak in our guest bathroom toilet. Thanks to Juan’s thorough work and dedication — and to Goettl for not charging overtime — our kitchen sink is back to normal and everything is running smoothly again. We’re truly grateful for the exceptional service Juan provided. Highly recommend him and the whole Goettl team.

Goettl came out to try to repair an aging unit for us 2 years ago. ended up purchasing a new one, and today Dylan G came out to give it a rejuvenation. He was great! Very cordial, informative, and detail-oriented. Got our unit refreshed for summer and I couldn't be more pleased!

Kaelen Nuss was sent to our home in response to a possible leak. He was very friendly and polite, but above all, was very knowledgeable and informative. He listened to our concerns and let us know what he was doing every step of the way. Great job Kaelen. We usually get a quick response from Goettl and this was again a good experience. We recommend Goettl for all your plumbing and air conditioning needs.
