At the time of its manufacture, Trane’s XL 1800 air conditioning series consisted of three models ranging from 3- to 5-ton capacities. These discontinued units have cooling capacities ranging from 38,000 to 59,5000 BTU/hour and are capable of reaching up to 18 SEER.
The XL1800 features dual-scroll compressors that the manufacturer says allow for cost-effective, two-stage cooling. In addition, this unit is promoted for its “whisper quiet” operation, through the help of compressor sound insulators and a two-speed fan motor.
A baked on powder paint finish, corrosion- and weather-resistant screws, a protective top, and galvanized steel louver side panels help protect the unit from weather extremes and maintain the exterior appearance over time.
Additional feature include electrical and refrigeration components located on one side for easy service, a two-row spine fin coil for efficient heat transfer, and external braze fittings designed to ensure a leak-free installation.
My Trane xl1800 2-stage air conditioner never worked right. They replaced both compressors at 3 months old but still no good. The small compressor runs until it goes into overheat and then the large compressor shuts down along with it. Breaks down once a month average since it was brand new. I had VP's crawling through my attic saying the installation was good. Trane quality control on-site saying it works as designed. This unit is a nightmare. $8000 installed. The math: 7 cooling- months a year for 8 years. That's $143 per month before paying the electricity bill and the repairman. High efficiency? Not!
Homeowner forums across the web post varying troubleshooting inquiries about the XL 1800. A weakening compressor, the system blowing warm air, electrical issues, and compressors that fail to turn on are some of the issues posted on hvac-talk.com and fixya.com.
However, in most of these queries, homeowners mention units nearing 10 years old but do not note any recurring problems. Contractors on hvac-talk.com also seem to like this unit, saying it is a quality unit, equipped with durable components.
Despite the mixed reviews on this unit, several consumers air complaints about Trane’s customer service and HVAC equipment. Reviews on consumeraffairs.com mentioned Trane’s poor customer service, low quality components, and frequently breaking systems.
