HVAC Manufacturers | Heating and Cooling

HVAC Manufacturers Heating and CoolingHVAC Manufacturers | Heating and Cooling - Heating and Cooling Manufacturers are always improving the energy efficiency of their products using innovation and modern technology to help. HVAC manufacturers are required by the government to increase the efficiency ratings of equipment sold. Usually, this is a mandate passed down by Congress that will set a standard for a minimum efficiency of air conditioners and heating systems. Usually, this mandate is the result of manufacturers, the department of energy, and other industry concerns meeting and agreeing to a new minimum that is more efficient and utilizes less energy than previous models and designs.

Condenser Coil Repair | HVAC Refrigeration

New Condenser Coil Repair - HVAC Crane LiftCondenser Coil Repair - A crane is used here to lift a new condenser coil to a rooftop. The old condenser coil was leaking and could no longer be repaired. The process involved recovering all the refrigerant from the Trane rooftop unit.

The rooftop unit was then partially disassembled and the old coil cut out from the system taking great care and planning to ensure the new coil could be retrofitted to the old refrigeration piping system.

Good planning and skilled HVAC techs make the jobs go smoothly and make the replacement seem easy especially to the customer. (more…)
