Oxbox HVAC Brand — Value-Priced HVAC Products Endorsed By Trane

Trane, Oxbox, American Standard & Ameristar are all owned by one company, Ingersoll Rand.  Trane & American Standard HVAC Systems are known for their durability, and are premium priced.

Oxbox HVAC brand was introduced in 2019  for those seeking a more affordable HVAC System.  Oxbox meets Trane’s brand approval for quality & durability.  Oxbox HVAC includes; air conditioners, heat pumps, and furnaces.  The components inside Oxbox HVAC units have been field-tested for over 5 years.

The question comes up: Are Trane & Oxbox the same?  No, Oxbox has a different brand compressor, and likely other components that differ from what Trane and American Standard uses.  This is why they are less expensive.  Later in this article, we provide details about the compressors used by all four brands.

Ameristar brand HVAC is an additional lower priced HVAC Line offered by Ingersoll Rand.  It appears that Oxbox brand & Ameristar brand are likely the same products, only with different brand labels.

Oxbox and Ameristar HVAC outdoor units look identical, except for the label.   We don’t know if they are identical inside.   Trane & American Standard HVAC have their proprietary ClimaTuff ® brand compressor.  Only Trane & American Standard HVAC have ClimaTuff® compressor.

Ameristar uses Copeland® Brand Compressors.  We could not determine if if Oxbox does too.  Copeland Compressors have been manufactured for over 100 years, and many HVAC brands have Copeland Compressors.

  • Ameristar’s M4AC4 is their 14-SEER Central A/C Outside Unit, available in 1-5 ton (12,000–60,000 BTU’s) sizes.
  • Oxbox’s J4AC4 is their 14-SEER Central A/C Outside Unit, available in 1-5 ton sizes.

Oxbox Warranty:  Year 1 includes the option to get a complete unit replacement if any main components fail (compressor, coil, or heat exchanger).  Then, the warranty is 5 years for standard parts & 7 years for the compressor (parts only, installation labor not included) .   Plus, the warranty applies to the home, not the homeowner.  The homeowner can date the warranty as the date they bought the home.  This eliminates losing some of the warranty coverage period if the owner bought a house that was vacant for a while prior to purchase.

Ameristar Warranty:  The standard parts warranty is 5 years, OR 10 years if the warranty is registered within 60 day of purchase (parts only, installation labor not included).

What’s More Important, The HVAC Brand, Or The Quality Of The Installation?

The Quality Of An HVAC System’s Installation Is More Important Than The HVAC Brand.  A premier brand HVAC System can’t perform as designed if it was installed poorly.  A value-priced system, that’s properly installed, will out perform a premier system that’s poorly installed.

With flexible ductwork, the quality of the installation becomes more important yet.   Flexible ductwork has specifications regarding the placement & spacing of ductwork hangers, and many other details.  If flexible ductwork is not installed as specified by its manufacturer, it can; sag, crimp, buckle, or collapse.   All of this leads to; higher cooling & heating costs, compromised comfort due to hot & cold spots, an HVAC System that breaks down more frequently, and does not last as long as it could have.

Here Are Some Examples Of PROPERLY Installed Flexible Ductwork

Compressor Brand For Trane & American Standard

Trane & American Standard Both Use Their Own, Proprietary Brand ClimaTuff ® Compressors.   DuraTuff compressor have a legacy of being reliable and long lasting.  In a testing lab in Tyler, TX,  a ClimaTuff® compressor (nicknamed Snowball 1) was put into service in late 1972.   Snowball lasted nearly 28 years under brutal lab conditions.  It ran at an estimated 3,500 rpm for 24 hours a day & 7 days a week.  This equates to an automobile running 60–70 miles per hour, non stop for nearly 28 years, and covering 14.8 million miles.

Compressor Brand For Oxbox HVAC & Ameristar HVAC (and most other brands)

Oxbox & Ameristar HVAC use Copeland brand compressors.  This is part of the reason they are less expensive than Trane & American Standard.  Copeland brand compressors have been manufactured for over 100 years.  This brand is in many (if not most) HVAC brands (except Trane & American Standard).   According to Consumers Reports, Trane received a score of 8 (out of 10) for reliability. Several brands that use Copeland compressors were rated 7 out of 10, so Copeland compressors are likely nearly as reliable.

One area where DuraTuff outshines Copeland is noise generated by a Heat Pumps during its defrost cycle.  Because a Heat Pump is an air conditioner running in reverse, the outside unit frosts and is automatically defrosted on a recurring schedule.  DuraTuff compressors are quieter during Heat Pump defrosting.   There is little difference in noise level at other times, and these comments apply only to Heat Pumps.

A SIDE NOTE — If You Currently Own A Noisy Heat Pump or A/C, This Product Can Help Reduce Noise

All Heat Pumps make notable amounts of noise during their defrost cycle.  Some brands will make more noise than others.  If you are bothered by the noise your air conditioner or heat pump makes, QuietFence is designed to dramatically reduce the noise.
