Signs You’ll Need Your Unit Changed

There comes a time in the life of every home appliance when it needs to be replaced by a modern, state-of-the-art model. Whether it’s due to the frequency and expense of repairs and maintenance calls, or simply the physical wear and tear it has suffered over the years, every AC unit’s value depreciates. By recognizing when your AC unit is closing in on the end of its usefulness, you can prepare to purchase a new one.

Installing a new air conditioning system can come at a high-cost upfront, but the money you save by running a new model with a higher efficiency rating could mean the unit pays for itself. Maintenance and repairs should be less frequent and the amount you save on your energy bill each month will be apparent. If you’re unsure whether or not you should buy a new AC system, ask a technician next time you make a service call if they think it’s worth the cost.


What is the Difference Between System Speeds

Single Stage

  • Like a light switch – on or off
  • When the temperature reaches a set target the system turns on – then turns off when it reaches target level
  • This cycles on and off
Single Stage


  • Similar to a room with the main set of lights and auxiliary lights around the room – they are turned on to add to the brightness
  • In a system the 1st cover approx. 60% of the capacity, when the demand is higher then the second stage turns on
  • The first stage is enough to cover a large part of the time and will be activated when the temps are high
Two Stage

Variable Speed

  • Like a dimmer switch – goes from low to high to any desired level
  • A variable speed will continuously adjust to the conditions
  • This gives the best comfort as it runs for long periods there is always some air flow
  • Also the most efficient as it is matching the required demand
Variable Speed
