PMC projects provide the best examples of the type of work we do. Here are a few projects we believe showcase some of our capabilities.

They all have one thing in common: satisfied clients.

Roof Tear Out

PMC can provide services such as a roof tear out. Typically this is needed at mall or commercial properties that do not allow curb adaptors on their roof. Pictures above show a total roof tear out of a 25 ton RTU performed by PMC. During this job we removed the existing unit, the original curb, and supply and return drops. We then installed a new curb and provided roofers to flash in so that the curb would be ready to set the new unit. PMC then installed new supply and return drops in order for us to tie into the existing ductwork. Once all was complete PMC provided a new 25 ton RTU for the new space. As always PMC provided customers with desired checklist and pictures throughout to show the production of the project.

Custom Sheet Metal & Blower housing repair on 50 Ton Condenser

PMC can provide several aspects of HVAC including on the job custom sheet metal fabrications. PMC conducted a blower housing changeout on a 50 ton unit. This included the blower wheel, shaft, bearings, and the housing. With the side walls of the AHU rusted and severely damaged we were able to use our custom sheet metal shop to fabricate on the job side panels.

PM Inspection – Preventative Maintenance

PMC conducts preventative maintenance for customers all around the state. PMC technicians are trained to take before and after pictures for any filters that have been changed as well as any parts that need to be replaced. Pictures can help show the pictures why we are quoting what we are quoting. By doing preventative maintenance; often times it can help the client help find potential issues before they occur.

Condenser/Evaporator Coil Cleaning

Cooling season often comes with condenser and evaporator coil cleaning. It is important for you to have a clean condenser coil to allow the heat to be removed from refrigerant. When this happens the refrigerant cools and turns into liquid to provide cooling from your system. The evaporator coils helps hold the chilled refrigerant that the compressor moves into the unit and also helps provide cooling to your system. Pictures above show PMC thoroughly cleaning the condenser coil  and evaporator coil using chemical cleaner.

Compressor Changeout

Compressors are one of the main components on the cooling cycle. This allows the circulation of refrigerant necessary for heat exchange through the coils of the unit. Pictures above show the heat exchanger being replaced as well as the filter drier.
