Signs that indicate the need for an AC unit change-out

    If you are not sure about an air conditioning unit replacement, here are some signs that could suggest that it is time to do it:

  • You have an old unit: if you have between 10 or 15 years with the same AC unit, this could be time to make the change, as over time, HVAC systems become less efficient and, even worse, suffer constant breakdowns, increasing repair costs.
  • Your AC is damaged frequently: if your air conditioning system demands continuous repairs, this is a sign that its life is ending and, at any time, will stop working.
  • Your electric bill increased: if the unit is not working correctly, it can improve the kW consumption per month in the building, which makes it less energy efficient, and implies a higher cost in the long run.
  • The unit makes an uneven cooling: if when you turn on your HVAC system, you notice that there is only cooling in some areas of your building, but other rooms are warmer, this indicates a malfunction.
  • You hear strange noises: one of the signs that least notice the owners are the noises and even strange smells when they have their AC units on, and these can be severe problems, which could alert you about a faulty motor or electrical failure.

  • Preparing the site and clearing obstacles: for the safety of the work area and easy access to the new unit, it is necessary to remove furniture, plants, and other objects that may pose an obstacle.
  • Disconnecting and removing the old AC unit: this step involves counting the power flow to the AC unit to be replaced, disconnecting all nearby electrical and water connections, removing the unit, and then disposing of it according to local protocols.
  • Installing and connecting the new HVAC system: placing the new unit in the correct location, connecting the wiring and piping, and lodging or adjusting the ductwork.
  • Testing and adjusting the system performance: includes testing the electrical connections and performing the load calculation to ensure it is ideally sized.

Key considerations during AC unit replacement

  • Upgrading to a more energy-efficient system: an air conditioning unit replacement saves money on electricity bills, benefits the environment by emitting fewer greenhouse gases, and gives you greater comfort and control over indoor temperature and air quality.
