When replacing the outdoor unit of an air conditioner,
should the indoor unit also be replaced?
We're glad you asked!
The answer is likely, Yes, and here are the reasons why:
Matched System Design
All air conditioner units are specifically designed to work with
matched indoor units for optimum efficiency and performance. The
result of this matched system is a coordinated, top performance
team that ensures the dependability and high efficiency today's
applications require. Air conditioner outdoor units may "work"
with indoor units other than those for which they have specifically
designedS however; the result is a definite compromise in system
performance.
Design Advances
Through the years indoor blower coils and units have undergone
numerous design advances especially in the areas of air handling
performance, filtering efficiency and operating sound levels.
A new outdoor unit will also include the latest design advances.
Higher Cooler Efficiency
The cooling and/or heating efficiency ratings that are advertised
for an air conditioner are based on performance as a matched system.
While changing only the outdoor unit may result in improved efficiency
compared to the old system, it will not be as efficient as it
was designed to be and your savings will be lower than with a
matched system. In addition, you will not get a new product equipment
warranty when installed with non-matched components.
Equipment Age
If an air conditioner outdoor unit is 10 years old and needs to
be replaced, the indoor unit is just as old and has been subjected
to the same amount of wear and tear. Replacing both units means
you wonąt then have to replace the indoor unit in a short timeSyou'll
have ten years of service from both units.
New Warranty
A new unit also gives you a new product warranty. Replacing the
indoor unit at the same time as the outdoor unit results in peace
of mind, knowing the new warranty covers the entire system.
A Bargain?
At first glance, replacing only an air conditioner outdoor unit
may appear to be a bargain. But when you consider the lower cooling
efficiencies, decreased reliability and the high cost of ownership
that results, it's not such a bargain after all! Replacing an
entire air conditioner system costs more, but you get moreSefficiency,
reliability and comfort.
