Earlier this week we mentioned that some air conditioning manufacturers are experiencing TXV failures and Nordyne was attempting to address the situation. Gemaire, an HVAC wholesale distributor, has also announces the increase frequency of thermal expansion valve failure rates. While the announcement does not mention particular brands affected, Gemaire distributes Frigidaire, Rheem and Maytag brands in the Tampa area. Below is an excerpt of the statement made by Gemaire:
As you may know our industry is experiencing metering device failure in the refrigerant cycle of split systems and packaged units. Gemaire is very concerned about this issue and want to share the information and knowledge that we currently have available from our manufacturers:
A sticky material is developing inside the refrigerant cycle and collecting in the metering device.
In the case of the TXV it is causing the metering pin to stick.
Split Systems as well as packaged products are impacted.
Manufacturers have informed us that they believe the TXV is not the root cause of this problem.
Date codes affected by this issue are random and fluid from our manufacturing partners.
All manufacturers are working diligently to resolve this issue with a great deal of testing in progress.
We are working closely with all of our manufacturing partners to obtain corrective actions for you but unfortunately none is available at this time.
Gemaire understands that you and your customers are frustrated with this situation and we want to assure you we are using our utmost influence to provide a solution and have this problem resolved as soon as possible.
We will continue to keep you informed as we get information and updates, and as always we value your business, loyalty, and patience during this period.
Failures such as these can impact many brands because they often use the same suppliers for many of the components within the system. This does not, however, appear to be an industry wide issue as there are a number of manufacturers and distributors that are experiencing little or no TXV failures. Call the air conditioning and heating pros at Melo Air if you have concerns about the TXV on your HVAC system.
