I am a consumer protection attorney working in Washington, DC and Maryland. My firm is investigating Carrier and Lennox air conditioners. It would be helpful to our investigation if we could speak to anyone who has such a unit installed in their home or business. If you are willing to have a brief conversation, I can be reached at 202-789-3960 or by e-mail at [email protected] Thank you in advance for your consideration. Brendan Thompson

Even though the ac is 8 years old I highly recommend to replace the condenser and evaporator.
Your old unit is a R22 unit, and the phase out process for that refrigerant has begun, so in a few years it will be either all gone or very expensive. I would install a r-410 unit, and confirm that it is properly sized. Do your home work on the quality of the brand of unit before buying.

Thanks for your question.

To both Debbie (BV00126) and Kevin (BV001949):
I have the same situation and questions as the 2 of you. In fact, I have read and found evidence of legal class action lawsuits under consideration towards Lennox, which is the brand I had purchased new, had professionally installed, serviced and maintained twice a year. Before the unit was 4 years old (only 3 summer seasons), the evaporator coil was shot and had to be replaced.

After I found out how difficult this 'coil' is to get to, I'm wondering the same questions as Debbie. It seems odd that the coil would perform perfectly for 3 summers and before the start of the next season, have such bad leaks that the coolant had almost entirely leaked out and the unit beyond repair. All of this without any indication of reduced coolant amount during any of the previous service/maintenance calls? The part they took out looked disgustingly old, worn, and corroded.

Before I pay any money towards the replacement work, I'm insisting from the 'Lennox contractor' that he provide answers to these questions, and may well visit a lawyer myself. I am tempted to bring an additional suit against the contracting agent for Lennox, since there is no possible way that they are unaware of this problem!

I'm curious as to what you may have found out, or your situations were resolved. Thanks!

I bought a new home with a Lennox A/C four years ago and was informed today that I need a new evaporator coil. The A/C stopped cooling and Freon was added. However, 10 days later, it needed Freon again and it was determined that the evaporator coil needs to be replaced. I am very upset about this issue because I feel ripped off by Lennox. The company should provide assistance in replacing this part.
