Cooling Your Home More Efficiently (Without Replacing Your System)
Living in any hot climate means your air conditioning system works overtime. The thought of high energy bills can be daunting for homeowners with older or struggling AC units. However, upgrading to a more efficient model is only sometimes financially feasible.
The good news is there are ways to enhance your cooling efficiency without a full system replacement. Follow these tips to save on your cooling costs. And if you need any AC services, remember that Goettl Air Conditioning & Plumbing is here to assist.
Utilize a Zone Control System
While investing in a zone control system may require upfront costs, it’s a more budget-friendly option than replacing your entire HVAC system. With a zone control system, you can set different temperatures for various areas in your home. It allows everyone to stay comfortable without overspending. Each zone is controlled independently using individual thermostats, which regulate electronic dampers in the ductwork to adjust the airflow as needed.
Cost-Effective Cooling Solutions
Investing in a zone control system is a cost-effective alternative to replacing your entire HVAC system. While upfront costs are involved, the long-term savings and comfort benefits make it a wise investment.
Tailored Comfort for Every Room
With a zone control system, you can set a different temperature in different areas of your home according to your needs. It means you can cool occupied rooms more effectively while allowing less-used areas to remain at a higher temperature, saving energy and money.
Individual Thermostats for Precise Control
Each zone in your home has its thermostat, giving you precise control over the temperature in each area. It allows you to set temperatures based on usage patterns and occupancy, ensuring comfort where and when you need it most.
Efficient Airflow Management
The electronic dampers in the ductwork regulate airflow to each zone, ensuring that conditioned air is distributed effectively. It improves comfort and reduces energy waste by delivering air only where it’s needed.
Maintain Your Ductwork
Damaged or compromised ductwork is a common cause of inefficient cooling. If you suspect your ducts are the issue, have them professionally tested, sealed, or repaired. Efficiently cooling your home is much easier when the cooled air can reach its intended destination without leakage.
Professional Ductwork Inspection
If you suspect that your ductwork is compromised, it must be inspected professionally. A qualified technician can identify any issues, such as leaks or damage, and recommend the necessary repairs or sealing.
Sealing and Repairing Ducts
Sealing or repairing damaged ducts is crucial for maintaining efficient cooling in your home. Leaky ducts can waste a lot of cooled air, forcing your HVAC system to work harder and consume more energy. Sealing and repairing ducts can enhance your cooling system’s efficiency and reduce your energy bills.
Improving Airflow and Efficiency
Properly sealed and repaired ducts can improve airflow throughout your home, ensuring cooled air reaches its destination without leakage. It improves the overall efficiency of your cooling system and enhances comfort levels in your home.
Insulation and Ductwork Efficiency
In addition to sealing and repairing ducts, ensuring your ductwork is properly insulated can improve efficiency. Insulation prevents the transfer of heat, allowing cooled air to stay at the desired temperature as it travels through the ducts. Proper insulation can also help reduce energy loss and boost the overall performance of your HVAC system.
Regular Maintenance and Monitoring
Regular maintenance and monitoring of your ductwork are essential for long-term efficiency. Schedule routine inspections to check for leaks, damage, or other issues impacting the performance of your ducts. Additionally, monitor your energy bills for any sudden increases, as this could indicate a problem with your ductwork that needs to be addressed promptly.
Utilize Fans and Ventilation
Fans for the ceiling and exhaust can help circulate air and remove heat from your home, reducing the workload on your AC system. Using fans strategically, such as running ceiling fans counterclockwise during summer to create a breeze, can help you feel cooler without lowering the thermostat.
Ceiling Fans for Air Circulation
Ceiling fans are an inexpensive way to enhance the circulation of air in your home. Run your ceiling fans counterclockwise during the summer to create a breeze that can make you feel cooler. It can raise your thermostat setting without sacrificing comfort, reducing energy consumption.
Strategic Use of Exhaust Fans
Exhaust fans in bathrooms and kitchens can eliminate heat and humidity from your home, reducing the workload on your air conditioning system. Use these fans when cooking or showering to prevent heat buildup and improve overall comfort.
Whole-House Ventilation Systems
Install a whole-house ventilation system to enhance the air quality indoors and reduce the need for air conditioning. It will replace stale indoor air with fresh outdoor air, reducing humidity and pollutants indoors. They can also help lower indoor temperatures, reducing the need for mechanical cooling.
Window Fans for Night Ventilation
Window fans are a great way to cool your home during the cooler evening hours. Place window fans facing outward in windows on the cooler side of your home to draw in cool air from outside. It can help reduce the need for air conditioning overnight, saving energy and money.
Utilize Natural Ventilation
Use natural ventilation to your advantage by strategically opening windows and doors. Cross-ventilation, accomplished by opening windows on opposite sides of your home, can create a natural breeze that helps cool your home. It can be particularly effective in the evening when outdoor temperatures are lower.
Shade Your Home
Shading your home from direct sunlight can reduce heat gain and help maintain a cooler indoor temperature. Planting trees or installing awnings, shades, or blinds can block sunlight and reduce the need for your AC to run continuously.
Planting Trees for Natural Shade
Strategically planting trees around your home ensures a natural shade, reducing the sunlight that enters your home. Deciduous trees, which shed leaves during the winter, can provide shade during the warmer months and allow sunlight to keep you warm in the winter, maximizing energy efficiency.
Installing Awnings for Sun Protection
Awnings installed over windows can block direct sunlight, reducing heat gain in your home. Retractable awnings allow you to control the sunlight entering your home, providing flexibility based on the season and time of day.
Using Shades and Blinds for Sun Control
Interior shades and blinds can be adjusted to block sunlight during the hottest times of the day, reducing the need for air conditioning. Choose light-colored shades to reflect sunlight and heat away from your home.
Applying Reflective Window Film
Reflective window film can be used on windows to lower heat gain by reflecting sunlight. It can help maintain a cooler indoor temperature and reduce the workload on your air conditioning system.
Creating Outdoor Living Spaces
Creating outdoor living spaces, like patios or pergolas, can provide shaded areas for relaxation and entertainment. Spending more time outdoors in shaded areas can reduce the need for indoor air conditioning, saving energy and lowering your utility bills.
Schedule Regular Maintenance
Regular AC maintenance can ensure optimal performance and energy efficiency. By scheduling routine maintenance, every system component can function properly, reducing the energy needed to cool your home.
Professional Inspection and Cleaning
Regular maintenance includes a thorough inspection and cleaning of your air conditioning system by a professional technician. It ensures all components are in good working condition and that potential issues are addressed early, preventing larger problems and costly repairs.
Filter Replacement and Airflow Check
During maintenance, the technician will replace the air filter to ensure proper airflow. A blocked or dirty filter can limit airflow, reducing the efficiency of your system. The technician will also check the airflow to ensure it meets the manufacturer’s specifications.
Checking Refrigerant Levels and System Efficiency
The technician will measure the levels of refrigerant in your system and recharge it if necessary. Low refrigerant levels can indicate a leak, reducing cooling capacity and increasing energy consumption. The technician will also check the overall efficiency of your system and make any adjustments needed to improve performance.

Update: 12/3/24 - Jacob is great. He fixed the leaking parts on water softener and also checked the water heater to see what can be done with that. He is efficient and very knowledgeable and reviews everything so you understand.

Update: 7/25/24 - had some more work done today. The folks who come to service, install, etc. are great. They know their job, are very efficient and friendly. Today it was Justin and Luis who were installing a new filter system. Looking forward to not have to change filters every month. Thank you, gentlemen, for all the hard work in the heat.
‐----‐-----------------------------
They said I needed to replace my a/c. I was given a choice of 5 units. I liked that the 2nd most expensive would balance the temperature in my house. I get full west in my living room in the afternoon. It is always 10 plus degrees hotter on my sofa, than rest of house. So I paid a fortune and it isn't doing what he said it would. They came back and added another vent to my living room. Better, but still not what I was told. I could saved $10k and got the cheaper model. Don't think I have much recourse to get this fixed. The technicians are very good, too bad their salesmen and products are not up to the same standard.


Blake was absolutely amazing from start to finish. He was friendly, personable, and genuinely took the time to listen to my concerns. He explained everything clearly, provided sound and honest guidance, and never once made me feel pressured. His professionalism and genuine care made it easy for me to trust him and feel confident in moving forward with this company.
Technicians like Blake are the reason customers stay loyal—he definitely deserves a raise. I’m truly blessed to have encountered him today. Thank you, Blake, for your outstanding service!










Thank you!!!




Original order of checking thermostat. And why heat would not kick on right away
It was taking several degrees to heat up the house. Air conditioning works great.
He went and checked thermostat and suggested a new thermostat. $800 for two installed. 👀
He then checked furnace in attic.
The fresh air exchanger was pretty dusty and he could clean it for under a hundred $. I said go ahead because exchanger runs ten minutes per hour to keep fresh air circulating. So price was $99. Still a lot for cleaning a screen.
It seemed to have worked in conjunction with thermostat because it’s been working properly since he left.
Im glad I didn’t spend $800. But only $228 .
Hope thermostat continues to work well
Thank you Jackie.
I still think prices are very high. You can buy and install a thermostat yourself for $175. With a $75 rebate. That’s quite a difference.


I also want to add that Taylor came to service my unit and she was amazing. My dog is usually sketched by most people and she liked Taylor. That's a huge plus.









Thank you Ian for my maintenance today!

Andrew is an outstanding representative of the company.
Thanks

We had Edgar come out to inspect our new home today and he did a very thorough inspection. He made sure the unit was checked so when the warranty company comes out we have all information possible. Amazing customer service and very personable
Edgar came back after a warranty inspection was done on the home by the install company. He found errors and was amazing at documentation of the issues. If I could give more than 5 stars I would.
Peter and Josue came out today to do an additional check on our unit with humidity issues. The weather was not conducive to having the outdoor pressures checked and they were very thorough with an interior check. Very professional and knowledgeable.






















I think the guy that was supposed to be assigned to me had problems. My appointment was from 9-1 and Austin was assigned to me at 1:30 and Drove over an hour to get to me.
Now that's 💜
11/24/25 Seems this is an update not its own post. Adam was out to repair our filtration system. No muss no fuss and it was fixed. Awesomely competent guy






Job done quickly and efficiently. Thank you





A special shout-out goes to Pablo, our technician. He was on time, friendly, and extremely knowledgeable. Pablo took the time to explain everything he was checking, walked me through the condition of each component, and gave helpful tips on how to keep our system running efficiently year-round. His attention to detail and pride in his work really stood out. Because of his professionalism and the overall quality of service, Goettl has definitely earned my trust and future business.

I have seen Goettl vans all over town and so I called them.
Got appointment right away and the Technician, Jef Eusepi, took care of our problem.


Call Goettl and was able to get us on the schedule due to a cancellation they had.
Jef Eusepi our tech was fantastic.
He explained everything and showed us pictures of what he was doing and fixing.
Would definitely recommend this Company and Jef.

He was knowledgeable and friendly and was able to flush the tank and get my hot water flowing again. Thanks again...




(Oldest)Jared was great. Got here promptly and fixed it quickly. Lifesaver on a 100+ degree day!












On time, clean, and very thorough with any potential issues.
Thank you.







Chris R came out for our Sadie Membership inspection and review before the cold comes here in TX. He did a fantastic job and really knows his stuff. Thank You!






Mike provided truly exceptional service. From the moment he arrived, it was clear he was extremely knowledgeable; he quickly and confidently diagnosed a very tricky issue that we had with our pipes, explaining everything clearly and answering all of our questions with patience. He also installed our new water heater and did an outstanding job. If you need a plumber who gets the job done right the first time, we highly recommend Mike. Thank you!






The Goettl team has been very professional and helpful to me as their customer. Thank you, Kelli Stoika.
PS… If there would’ve been 6 stars on the scale, that’s what I believe they should’ve received.

Thank you,

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.

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.
Sincerely, June Jones

And I would highly recommend the company and the quality technicians like Jarod.
