Rooftop and DX Equipment

Comfort Systems USA Southwest is highly skilled when it comes to the retrofitting rooftop and direct expansion cooling (DX) equipment. Like many packaged air conditioning units, DX units contain a refrigerant coil placed directly in the supply air stream, causing the refrigerant to evaporate and expand, removing energy and lowering the temperature of the air. If not properly maintained, or when it is nearing the end of its useful life, replacement may become necessary.

Servicing Your Rooftop Equipment

We all know that properly maintained equipment operates more efficiently. For HVAC equipment, regular maintenance can also reduce your carbon footprint, electrical usage and expenses. Routine maintenance of your rooftop and DX equipment should include the replacement of filters and belts as needed, as well as lubricants.

To ensure your equipment is being properly maintained, contact us at any time to learn more about our diverse, professional and customizable service agreements.
