Professional HVAC Services in Mount Prospect, IL 60056 - D & J Heating and Cooling

High energy bills are a common concern, often caused by inefficient or aging systems. We address this by first performing a detailed assessment of your current furnace or air conditioner. Many times, the solution can be a thorough maintenance service to clean components and ensure peak efficiency. If your system is over 15 years old, we can discuss replacement options with high-efficiency models, like those from Lennox, which we are authorized to install. These modern systems are designed to use less energy while maintaining comfort, helping to reduce your monthly bills significantly.

Our maintenance service is a comprehensive check-up designed to prevent problems and extend the life of your system. For your furnace, this includes inspecting the heat exchanger, cleaning the burners, checking safety controls, and testing system operation. For your air conditioner, we clean the coils, check refrigerant levels, inspect electrical components, and ensure proper airflow. This proactive approach helps catch small issues before they become major repairs, improves efficiency, and maintains your manufacturer's warranty. As your local HVAC experts, we service all makes and models.

With over two decades of combined experience, we specialize in proper system sizing and installation, which is critical for long-term efficiency and comfort. We are an authorized Lennox dealer, offering quality, high-efficiency equipment, but we will work with you to find the right solution for your home and budget. Our process includes a detailed load calculation to ensure your new furnace and AC are perfectly matched to your Mount Prospect home. We stand behind our installation work completely, treating your project with the same care we would for our own neighbors.
