Why Are There So Many A/C Brands?

Why do six companies make 24 A/C brands? Most HVAC brands offer 2 to 3 price-points: “Good, Better, & Best.”  They often have a different brand name assigned to each price point.


  • Trane HVAC sells two “Best” brands — Trane and American Standard.
  • They also sell two “Good” brands: Ameristar and Oxbox.
  • The “Good” brands don’t use the same components the “Best” brands use.   They have a Copeland ® brand compressor.


Trane & American Standard Brands Have A Proprietary “Clima-Tuff” ® Brand Compressor (they make it themselves)  

This story tells of the reliability and longevity of the Clima-Tuff ® brand Compressor

Snowball I was the original Climatuff® compressor.  It began its life in late 1972 and ran for nearly 28 years.  It ran at an estimated 3,500 rpm — equaling an automobile running 60 — 70 miles per hour, and covering 14.8 million miles.  Five presidents later — and after the rise & fall of; disco, glam rock, and grunge music,  Snowball finally ran out of steam — and created a legacy for the Trane Climatuff® compressor, found in every Trane air conditioner and heat pump today. **

Snowball II is the current Climatuff® compressor located at Trane’s Compressor Test Lab in Tyler, TX.   Snowball II has been running nonstop since 2000 — and is inside a block of ice that it created.  Our technicians have tried to break our Climatuff® compressor over 900 ways.  Trane says” “If a product doesn’t make it through our test lab — it doesn’t get made.”

Are Climatuff® compressors superior to Copeland?   That answer would be an opinion — we provide only facts.

In 2019, Consumer Reports Magazine did a study of their members — for 21,770 central A/C systems installed between 2007–2018. 

Predicted Reliability (highest score = 10).  Ratings below are based on a statistical model that estimates problem rates within the first 5 years of ownership.

8  Trane

7  American Standard

7  Bryant, Carrier (same company), Lennox

6  Amana & Goodman (same company), Day & Night, Payne, Rheem, Rudd, Tempstar

The Contractor Installing A New HVAC Is As Important (or perhaps more) Than The HVAC Equipment Brand

A “Good” HVAC brand with an excellent installation — will likely outperform a “Best” brand with shoddy installation.   Particularly with flexible ductwork — (which is used in most new HVAC System Installations) — if the ductwork is not installed correctly to specifications — the HVAC System will perform poorly.

Air-flow through an HVAC System is one of the most important operating characteristics.   If ductwork is poorly installed — or is too small for the furnace — airflow is compromised, and the System can’t perform as it was designed to.   This condition will; reduce comfort, raise cooling & heating costs — and will wear the System out faster.  It can also cause the furnace to overheat and shut down to protect itself.  The furnace will start running again once it’s cooled down — but will become damaged by multiple overheating-events.

TIP:  Tell your contractor you want photos of all the flexible ductwork once it’s installed.


All HVAC Brands (except American Stanard & Trane) — Use Copeland BrandCompressors.

There might be an exception somewhere — but it’s rare.


Copeland Scroll™ UltraTech™ Compressor

In 2016 — Copeland announced a Second-Generation, Variable-Speed Compressor(s) began production.  Copeland originally began making Variable-Speed, Scroll, Compressors in 2011. **

In January of 2017 – Copeland announced a Second-Generation, Two-Stage A/C Compressor.   The second-generation, two-stage, Scroll, A/C compressor operates at 65% & 100% capacity — to more closely match cooling-output to the home’s current cooling-demand.  Two-stage compressors deliver higher energy-efficiency when operating at the lower capacity (during milder weather).

What Is A Scroll A/C Compressor?

A Scroll Compressor contains 1 fixed coil in the center of the unit.  A second coil rotates around that fixed coil The rotating coil pushes refrigerant towards the center, which compresses it.   Until recently the Scroll A/C Compressor operated at only 1 speed.  As compared — reciprocating (piston) Compressors can operate at many different speeds.

Now, Copeland brand Scroll compressors are make as Single-speed,  Two-Speed, or Variable-Speed.   Two-stage units provide either partial-load & full-load capacity within a single compressor.  Scroll compressors change speed while they are running.   Reciprocating compressors operate at partial-load capacity — by shutting off some of their cylinders.  Depending on the size of the compressor, a reciprocating compressor can have as many as 8 cylinders.

What Is A Reciprocating (piston) A/C Compressor?

The reciprocating (piston) compressor is the most common.  A piston compresses the refrigerant by moving up & down inside a cylinder (much like a car engine).  As the piston moves down, it draws refrigerant into the cylinder.  As the piston moves up– the gas compresses.
