A Compressor Overhaul in HVAC involves a comprehensive inspection, cleaning, and refurbishment of the compressor components to restore it to like-new condition, improving performance, preventing breakdowns, and extending the equipment's lifespan. This service is a proactive measure to maintain comfort and ensure the efficient operation of HVAC systems.

Gas charging in HVAC systems, also known as refrigerant charging or regassing, is the process of adding or replenishing refrigerant gas to ensure the system operates efficiently and provides adequate cooling. This involves several steps, including pre-charging checks, evacuation, and the actual charging process, along with safety precautions.

Vacuuming refers to the process of removing air and moisture from a refrigeration or air conditioning system before it's recharged with refrigerant. This is done to ensure optimal system performance, prevent corrosion and ice formation, and maintain the longevity of components. A vacuum pump is used to lower the pressure within the system to a very low level, effectively removing unwanted gases and moisture.

Leak testing is a service that identifies leaks in heating, ventilation, and air conditioning systems, ensuring optimal performance and efficiency. It involves using various methods like bubble testing, infrared thermography, or tracer gas to detect leaks in ducts, pipes, and other components. Addressing leaks promptly can improve safety, reduce energy costs, and extend the lifespan of the HVAC system.
