Air Conditioning Installation

Now that you have chosen the perfect air conditioning system for your home, the next step is getting that massive apparatus installed. This may sound like a straightforward task, but you’d be surprised at how many times the installation process is done incorrectly. This is why it is so important to hire an experienced, trustworthy technician who is exceedingly skilled in his craft. Improper air conditioning installation is the primary culprit in many early air conditioning problems. It can also lower your heating and cooling system’s efficiency by up to 30 percent. That will increase your utility bills and shorten the life of your new system.

Common air conditioning installation mistakes include:

  • Not vacuuming all the air and particles out of the refrigerant’s copper piping, also known as the lineset.
  • Not properly sealing the plenum, ducting, or return air grille.
  • Not verifying that the return air grilles are the right size.
  • Installing the outside unit on a platform that is not level.
  • Not installing a trap for the condensation line.

These mistakes can be very costly, so they are best avoided. To prevent an improper installation, make sure your contractor follows Energy Star’s guidelines based on specifications provided by the Air Conditioning Contractors of America.

During installation, your contractor should:

  • Inspect and seal your home’s duct system. Some retrofitting or additional ducts may be needed to accommodate the new A/C system.
  • Verify that the refrigerant level in the new system is correct. Incorrect levels can lower efficiency by up to 20 percent and even cause a system breakdown.
  • Provide sufficient space around the unit for future maintenance.
  • Test for correct burner function and venting.
  • Install a compatible indoor coil when an outdoor unit is to be replaced in order to reach the highest level of efficiency for the system.
  • Place the condenser in an area protected from weather or landscaping.
  • Verify that the refrigerant pressure and the airflow across the indoor coil meets manufacturer specifications.
  • Install a programmable thermostat.
  • Show you how to replace the air filter.

If you’re wondering how long the central air conditioning installation process takes, this depends. If new ductwork needs to be installed and electrical issues arise, the entire installation may take about two to three days. But if no complications arise, then it may very well take half a day. Each situation is different, but an average installation will take about a day’s work.
