AC Pro Tip: Change Your Air Filter Regularly
When you think of air filtration, you probably think of improving the quality of the air throughout your home. In truth, though, this is not the primary function of the air filter in your AC system, though failure to change that air filter as needed can certainly lead to issues with one’s indoor air quality. As you’ll see below, changing one’s air filter in accordance with manufacturer recommendations can benefit the homeowner in a number of different ways. Just make sure that you are following directions properly, that you are installing your replacement filter carefully, and that you are using the right filter for the job.

Benefits of Changing Your Air Filter Regularly
When you run your air conditioner in order to cool your home, you probably want to do so in the most efficient manner possible. Well, this will simply not be the case if you fail to change your air filter as required by the system and circumstances within your home. If your air filter is clogged up with pollutants, after all, your system will have to work harder and harder in order to force air through it. This additional work means that your air conditioner will work harder than it should have to in order to cool your home, driving efficiency levels down.
Not only will failure to change your air filter regularly drag down efficiency, but it can also lead to excessive wear and tear on your system, which can in turn lead to operational problems. When your system must struggle to force air through its filter, it is at increased risk of damage. Plus, reduced airflow can lead to icing of the coils, further complicating matters. Also, if the filter is too clogged, air may get around the filter, and pollutants with it, resulting in reduced indoor air quality. Make the smart choice, and change your air filter as needed.

We are true believers of Goettl and will definitely use them in the future!







I also want to give a big shoutout to the management team. it’s clear they really care about their clients but, even more importantly, they take care of their team. That kind of support really shows in the quality of the service. I will definitely be using Geottl for future plumbing needs.


He was on time, very polite & professional, walked us through the HVAC Rejuvenation testing and shared all results.
Really appreciate the time he took to explain, wearing the booty covers on his shoes and follow-up afterwards.
Excellent service!
What more can you ask for….
Gratitude.

The Service Manager reached out and we spoke, he explained the reason for the high cost of the repair and offered to credit our account with a substantial amount,
This is a company that stand to what they advertise and their workmanship is above what they promise.
I would recommend this company to all my neighbors.
I also enrolled into their monthly membership to come out twice a year and check everything out.
Thank you for standing behind your work….
Have been trying to speak to a Service Manager since Sunday the 26th of October, it is now October 29th called every day but no answer.
I was billed $270 for 50 minutes of a copper pipe repair, and over $600 for a close to 18 inch pipe with a fitting.
The repairman man was cordial,, it’s the company Goertl that is not a good customer friendly company. When I called to dispute the charge I was told that they are the most expensive company around. Shame. shame, also it’s a veterans owned company and they only gave a 5% discount to us because of my husband being a veteran.
Our dispute is on the cost of material, hence the hole where pipe need repair was pre prepped.
All main valves were shut off and pit was dried.

We are confident that our system will be amazing , are thankful that Mike provided us a good experience.















Great service!

What really stood out was his deep knowledge and attention to detail — he didn’t just do the job, he made sure we understood what was causing the issue and how to help prevent future problems. It’s rare to find someone so thorough, respectful, and genuinely dedicated to doing the job right.
Rodell represented Goettl with true professionalism, and we couldn’t be more pleased with the service. Highly recommend both Rodell and Goettl for anyone needing expert, trustworthy plumbing service!

Thank you Kevin... Blessings








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!


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

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!


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.
