We participate in the effort to recycle all mercury bulb thermostats. You have seen them; every house had one. There were the round dial thermostats and the lever adjusted thermostats with an internal mercury ball. For the last decade we have been sending these controls to a recycling station in sealed containers to prevent mercury being released into landfill sites. We follow prescribed guidelines for recycling refrigerant, claiming it and returning it to manufacturers for reprocessing, preventing the release of harmful gases into the atmosphere. We guarantee your old equipment will be removed from your property and recycled. In special cases we use Technical Standard and Safety certified removal companies who observe removal and disposal protocol for hazardous wastes such as fuel oil and asbestos. These HVAC companies and their employees have the licenses, the insurance and the experience to do the work for which we contract them.
