From Old to Efficient: Daikin Installed
At Stay Cool Air Conditioning & Heating, we pride ourselves on transforming outdated systems into modern, energy-efficient solutions. Recently, we had the opportunity to work with Winston Shaffer, who came to us seeking a replacement for his aging 20-year-old Trane XR-12 heat pump affected by a landscaping mishap. Winston had done thorough research and set his sights on the latest technology, specifically a system that utilizes the new R-32 refrigerant.
Before: A 20-Year-Old Heat Pump
When Winston first reached out to our team, his Trane heat pump was not only outdated but also had sustained damage that left it non-functional. With a desire for better efficiency and performance, he wanted to take advantage of the advanced features available in contemporary systems. The goal was clear: replace the old unit with a modern, reliable solution that would last for years to come.
The Transformative Process
After meeting with Winston at the San Antonio Home & Garden Show, we laid out a plan for the installation of a new Daikin Fit heat pump. This unit is known for its advanced variable-speed motor, allowing for exceptional humidity control and quieter operation.
Here’s what we accomplished during the installation:
1. Installation of the Daikin Fit Heat Pump: We expertly replaced the old system with a new Daikin model, which uses advanced technology to enhance energy efficiency.
2. Upgrading the Electrical System: Recognizing the potential hazard of Winston’s oversized breaker, we conducted an upgrade to ensure it would safely accommodate the new unit. This approach not only met code but also enhanced safety.
3. Surge Protection and Efficient Drainage: We installed surge protection to safeguard the system and rerouted the condensate drain cleverly to water Winston's landscaping, making it both functional and environmentally friendly.
4. Attention to Detail: Our team took great care in sealing all electrical conduits properly and providing clean, aesthetic copper piping for a polished look.
To safeguard the outdoor unit, Winston creatively decided to pour a hefty 5x6 concrete pad. After the main installation, we returned to anchor the new unit securely, completing the job with precision and pride.
After: A New Era of Comfort and Efficiency
The results of our work speak for themselves. Winston now has a state-of-the-art heat pump that not only meets but exceeds his expectations for energy efficiency and reliability. He noted in his review,
> “Stay Cool delivered expert craftsmanship, clear communication, and above-and-beyond service… I feel prepared and confident in this system for the next 20 years.”
Not only did we help ensure Winston's home stays cool, but we also made a long-term investment in his comfort as he approaches retirement.

Transforming HVAC Comfort for Our Clients
Transforming HVAC Comfort for Our Clients
At Stay Cool Air Conditioning & Heating, our mission is to ensure that families in San Antonio enjoy comfort and peace of mind throughout the year. Recently, we had the privilege of working with Arthur Flores, who sought our help to replace his old, failing HVAC system and ensure his home remained comfortable during the hot Texas months.
Before: A Failing System
Arthur reached out to us as his old HVAC unit was at the end of its lifecycle, leaving him with inadequate cooling in his home. After conducting thorough research, he decided that a variable speed system would best suit his needs. After initially narrowing down his options to either a Daikin Fit or a system from another local company, he chose to consult with us at Stay Cool. His concerns about choosing the right system and contractor made this decision pivotal.
Our Expert Guidance
As soon as Arthur contacted us, we assigned Chris, one of our knowledgeable technicians, to assist him through the selection and installation process. Chris was not only instrumental in advocating for the superior Daikin system, but he also made sure to communicate transparently and patiently throughout their discussions. Arthur mentioned how Chris’s professional demeanor and the absence of high-pressure sales tactics made him feel comfortable with his choice.
Once the system was selected, our installation team, composed of Hunter, Dakota, and Santos, took over. Their efficiency and attention to detail were commendable—they ensured that the installation was swift while also taking care not to damage anything in Arthur's home. Arthur appreciated their responsiveness and the fact that they left the area clean after the job was completed.
Challenges and Solutions
During the installation, there was a hiccup with a UV light component that was not functioning correctly. However, our commitment to customer satisfaction shone through. Chris reassured Arthur that they would replace it if it did not activate after a short period. When it didn’t, Arthur called us, and Tony from our team promptly arranged to inspect the system. After further evaluation, he ensured a proper replacement of the UV light while also providing a sanitizing service to guarantee optimal performance.
After: Peace of Mind and Exceptional Service
Arthur's experience didn’t end with the installation. As part of his first year’s maintenance plan, we provided regular upkeep to ensure the new Daikin system performed flawlessly. Recently, Christian completed the final service of the year, further impressing Arthur with his knowledge and respectful attitude. Arthur noted,
> “Stay Cool proved to be fair, professional, and offered great service throughout the HVAC replacement ordeal, which is usually not something consumers look forward to.”
We are proud to have not only met but exceeded Arthur's expectations. His feedback encapsulates our dedication to customer service—it's about creating relationships, ensuring comfort, and maintaining transparency throughout the service process.

At Stay Cool Air Conditioning & Heating, we pride ourselves on offering exceptional HVAC services to our valued customers in San Antonio. When Sean D. reached out to us in July 2025, he was experiencing ongoing issues with his air conditioning system. Recognizing that air conditioning is vital for comfort in Texas summers, Sean needed a reliable solution and trusted us to restore his home’s cooling effectiveness.
The Challenge: Intermittent Cooling Issues
Sean’s troubles began when he noticed his air conditioning unit cooling sporadically. Initial diagnoses revealed wiring issues and drainage challenges, causing significant discomfort, especially during sweltering nights. Recognizing the urgency, Sean contacted our team, and we promptly sent Dion to assess the situation.
As Dion arrived, he meticulously investigated the problem, discovering frayed wiring connections within the outdoor unit. This was not only obstructing full cooling efficiency but could potentially lead to further complications. With our commitment to thorough service, Dion addressed the wiring issues and ensured that the home was cooling adequately before leaving that evening.
> “Dion did lots of troubleshooting and found some fires inside the outside AC unit that looked to be frayed and not making contact all the time... When he left late, the house was cooling down and we were able to go to sleep.” — Sean D.
Comprehensive Repairs and Upgrades
Over the next several weeks, our dedicated team returned multiple times to ensure that every aspect of Sean’s HVAC system was functioning properly. Here’s a summary of what we accomplished:
1. Installed a UV Light: Dion expertly installed a UV light to enhance air quality by reducing microbial growth inside the unit.
2. Replaced Faulty Wiring: After extensive troubleshooting, we identified and replaced a faulty 240 wire connecting the inside and outside units to ensure reliable operation.
3. Drainage Solutions: Our technician, Tony, corrected a water drainage issue that arose due to improper installation, facilitating optimal airflow and preventing leaks.
Sean expressed his satisfaction with the comprehensive solutions we provided, continuously praising the professionalism and expertise of our technicians. We made it a point to thoroughly communicate every step of the process, which helped Sean feel secure about the work being performed on his HVAC system.
> “Dion was very professional, cordial, explained how everything worked, and did a great job with install and cleanup,” Sean noted after our technicians completed their visits.
The Results: A Comfortable Home
By the end of our service, Sean’s air conditioning system not only met but exceeded expectations. The once problematic unit was now fully operational, providing consistent and reliable cooling. Sean could enjoy his comfortable home without the worry of unexpected breakdowns or intermittent cooling.
