New HVAC Systems & Replacements

At Big D Mechanical, we focus on variable speed comfort systems. These state-of-the-art HVAC solutions deliver unmatched energy efficiency, pinpoint temperature control, and whisper-quiet operation to enhance your indoor comfort experience.

Unlike traditional HVAC systems that operate at a single speed or a few fixed speeds, variable speed comfort systems can automatically adjust the speed of their compressors, fans, or blowers to match the current heating or cooling demands. This continuous adaptation enables the system to maintain a consistent temperature throughout your space, reducing temperature fluctuations and enhancing overall comfort.

As premier comfort specialists, our team has the knowledge and experience to help you navigate the world of variable-speed comfort systems. We will assess your specific requirements and recommend the most suitable system for your home or business. Our skilled technicians will ensure a seamless installation process, optimizing your new system for peak performance and efficiency.

We partner with American Standard Heating & Air Conditioning, the industry-leading manufacturer of reliable, energy-efficient, innovative HVAC equipment. Our commitment to quality ensures you receive the highest performance and durability from your HVAC system.

Preventive Maintenance

Regular maintenance of your HVAC system not only ensures its continued operation but also helps you avoid costly repairs or premature replacements.

At Big D Mechanical, we understand the importance of keeping your system in prime condition. Our preventive maintenance plans are specifically tailored to maximize the performance of your HVAC system while minimizing energy costs. By regularly servicing your system, we can identify and address potential issues before they escalate into more significant problems, ultimately reducing the risk of unexpected breakdowns and enhancing the overall comfort of your living or working space.

We recommend a tune-up in the spring and fall to ensure your system is running smoothly for the upcoming more severe weather. We thoroughly inspect, clean, and service your HVAC system as part of our preventive maintenance plans. This comprehensive approach includes checking all components, such as filters, coils, belts, motors, and electrical connections, ensuring they are in good working condition.

In addition to the routine maintenance, we also assess the overall efficiency of your system and make necessary adjustments to guarantee optimal performance. Having your HVAC system regularly maintained allows you to enjoy a comfortable and energy-efficient environment all year. Additionally, our maintenance plans offer peace of mind, knowing that your investment in a high-quality HVAC system is cared for by experienced professionals who prioritize your comfort and satisfaction.
