Installing a new air conditioning system is a significant investment for any homeowner or business. In Rockwall and surrounding areas, D-N-D Services has been providing expert AC installations since 1997, helping clients make informed decisions to ensure comfort, efficiency, and long-term performance. Before scheduling an AC installation, asking the right questions can save you time, money, and frustration. Here are the top five questions to consider.
1. Is the Contractor Licensed and Certified?
One of the first things to confirm is whether the HVAC contractor is properly licensed and certified. Working with a licensed professional ensures compliance with state regulations and safety standards. At D-N-D Services, all technicians are NATE certified and our company holds a Texas HVAC contractor license. This level of training and certification guarantees that your installation will meet industry standards and that the contractor is qualified to handle all aspects of the job, including complex ductwork and high-efficiency systems.
2. What Type of AC System is Best for My Property?
Not all air conditioning systems are created equal. Factors such as square footage, ceiling height, insulation, and number of rooms affect the type and size of system you need. Professional contractors perform a Manual J load calculation to determine the proper system capacity for your home or business. Asking this question ensures that you won’t end up with an over- or under-sized system, which can lead to uneven cooling, higher energy bills, and increased wear on your equipment.
3. What is Included in the Installation Service?
AC installation involves more than just placing the unit and turning it on. Proper installation includes connecting the refrigerant lines, testing electrical components, sealing and insulating ductwork, and verifying airflow and thermostat functionality. Ask your contractor for a detailed list of services included in the installation. At D-N-D Services, our team handles every step of the installation process and ensures that your system is running optimally before leaving your property.
4. Are There Warranties and Maintenance Plans?
A reliable contractor should offer warranties on both the equipment and the installation work itself. Equipment warranties protect against manufacturing defects, while labor warranties cover mistakes or issues arising during installation. Additionally, ask about maintenance plans that can prolong the life of your system and maintain efficiency. D-N-D Services provides comprehensive warranties and offers routine maintenance services, helping you avoid costly repairs in the future.
5. What Are the Energy Efficiency and Cost Implications?
Modern air conditioning systems vary widely in energy efficiency, measured by SEER (Seasonal Energy Efficiency Ratio) ratings. Higher SEER ratings often result in lower energy bills, but the initial cost may be higher. Ask your contractor to explain the efficiency options available and provide a transparent quote including equipment, installation, and any potential savings on energy costs. At D-N-D Services, we help clients find the right balance between upfront cost and long-term savings, including options for high-efficiency systems like Carrier Infinity and Amana 18+ SEER models.
Conclusion
Scheduling an AC installation is a major decision, and asking the right questions can help ensure a successful outcome. Confirming licenses and certifications, understanding system options, clarifying what’s included in the installation, reviewing warranties and maintenance plans, and evaluating energy efficiency are all essential steps. With over 25 years of experience serving Rockwall and surrounding areas, D-N-D Services combines expert knowledge, professional installation practices, and a commitment to exceeding customer expectations.
