Picture this scenario: your air conditioning unit on the inside is running as it should, but the one outside has stopped doing its job. You are currently considering whether it is doable to replace the outdoor unit by itself.

Simply replacing the outside AC unit on your own can result in even more issues, some time in the future. What initially may appear to be a low-cost alternative may wind up being far more expensive. Because of this, it is sometimes not possible to replace the outdoor air conditioning unit by itself.

Why is it difficult to replace the outside AC unit?

  • There are compatibility concerns between new and old air conditioning units: The age of your HVAC system is one of the critical variables that add to the impossibility of simply replacing the outdoor air conditioning unit. The design of air conditioning units has improved over time. As a result, many older air conditioning units are not compatible with more contemporary versions. 
  • You Run the Risk of Voiding Your Air Conditioner’s Manufacturer’s Warranty: During AC’s installation in Hudson in your home, you would have received a warranty from the manufacturer. If a component breaks due to a manufacturing defect, you will be covered by this warranty. However, most customers are ignorant of the essential condition of these warranties.
    To maintain the guarantee on your air conditioning system, it is vital to match the indoor and outdoor units. This suggests that replacing even one of these components, such as a malfunctioning outdoor air conditioning unit, will void the manufacturer’s warranty.
  • Having HVAC Units That Do Not Complement Each Other Causes Chaos: Even if you could find a replacement outside air conditioning unit that uses the same refrigerant as your indoor system, industry pros would advise against replacing just the outdoor unit. There are numerous distinctions between the various types of air conditioning systems. The size of the evaporator coils in your indoor unit may not be compatible with the size of the condenser coil in the outdoor replacement unit. 

What are the advantages of replacing interior and outside air conditioning units?

If the outdoor unit is malfunctioning, you should also consider replacing the indoor unit to prevent further troubles.

You will gain the following advantages by installing modern air conditioning:

  • Lowering the costs of cooling.
  • Adding more comfort and coziness to your house.
  • Preserving the validity of your assurance.

Replacing every HVAC system component is always better when we perform a renovation, especially on older units. This includes the inside-outside split system units and as much of the ducting as is accessible without demolishing walls.

When Is It Appropriate To Replace One Of The System's Components?

While it is in your best interest to replace your air conditioning systems, if your outdoor unit is malfunctioning, it is sometimes possible to fix only the faulty component. For example, if your air conditioner is between three and five years old, you may still be able to utilize the warranty coverage.

As the indoor unit is only a few years old, a comparable outdoor unit will be sent to your property. Both teams need to be replaced if the age exceeds a particular threshold. However, you should hire an HVAC professional and consult them to choose the most effective course of action.
