Installing a new central cooling system can be a sizable job, and it is definitely one to leave to the professionals. There are many steps in the process, and naturally you may want to know what to expect before the work starts. Here’s a step by step guide of what your Plainfield HVAC technicians will do when installing your central AC.
- A spot will be chosen for the condensing unit outdoors. There are many factors to be considered when choosing this location, such as evenness of the ground, sunlight exposure, and code regulations concerning proximity to gas and electric meters.
- A hole will be cut near the condensing unit, towards the bottom of your home. This will allow necessary wires and pipes to enter the structure.
- If you do not have an air handler or a cased coil, an evaporator coil will be installed in your furnace. A line set will connect the condensing unit to the evaporator coil.
- High voltage connections will required, as central systems run on 220 volts of electricity. Regulations call for safety/disconnect switch to be place by the condensing unit. This is definitely a job for a professional.
- Once this is done, the low voltage wiring to the condensing unit will be completed. This will run to your thermostat. If your thermostat does not have both heating and cooling setting then a new one will have to be installed.
- Finally, drain tubing will be hooked up to the evaporator coil, allowing the condensed water on the coil to empty into a floor drain. Now all that’s left is for your HVAC technician to solder your copper refrigerant lines and release refrigerant in the system. Pressures will be balanced, the high voltage wiring will be connected, and the entire system will be inspected. Your central system is now ready to go.
Remember, the installation of a central air conditioning unit is a big job, especially if you do not have preexisting ductwork in your home. Certain steps of the process can legally only be performed by certified Plainfield HVAC technicians. Call DuAll Heating & Cooling with any questions you have about installing central air in your home.
