Carrier Corporation "Design-defective" components installed in heat pump Palm Beach Gardens Florida

I purchased a newly built home in October 2020. The Carrier heat pump with model CH14NB042P0G - serial 1320x95316 and model FX4DNF043L00E - serial 1420F22700 were installed there. Since the installation, I have been experiencing persistent issues, including multiple breakdowns and necessary replacements of essential components. Considering the frequency of repairs, I believe this unit to be defective or at the least, contain "design-defective" components. One part has been replaced twice already - The first time was 19 months after the new home was purchased and the second time was 20 months after the first replacement.

On January 23, 2024, I initially reached out to Carrier, via their online contact form, regarding the problems I was facing with the Carrier Heat Pump in my home, expecting a solution. They did not reply.

On Jan 30, 2024, I sent another online contact form. This time Dianne did reply, via email, the same day asking for information about the heat pump. A case number was assigned - case 5598484 [ref:!00D150EI7O.!5004R023rQl0:ref]. I replied to the email and provided detailed information, via email, including the model and serial numbers, date of unit installation, name and number of the installer, name and phone numbers of any service companies that worked on the unit, and copies of service tickets,  as requested by Carrier.  They did not reply.

On February 6, 2024, I sent another email asking for an update to the status. They did not reply.

On February 13, 2024, I sent another email asking for an update to the status. They did not reply.

On February 21, 2024, I sent another email asking for an update to the status. They did not reply.

On February 28, 2024, I sent another email asking for an update to the status. They did not reply.

On March 5, 2024, I sent yet another email asking for an update. They did not reply.

By March 11, 2024, they have not replied.

The lack of resolution and communication from Carrier has resulted in uncomfortable - read unbearably hot days and uncomfortable cold days, without a working air conditioner or heater and financial burdens for an almost new heat pump due to recurring repairs, which according to one service technician, one of the parts (dual capacitor) is designed to fail every two to three years.

I have attempted to resolve this matter amicably on a weekly basis by communicating directly with Carrier through multiple emails, yet my efforts have been met with complete silence and neglect, save the one and only time a reply was sent to me.

I am seeking an immediate, effective resolution to the issues I am facing with the Carrier heat pump. This includes a comprehensive assessment of the unit, reimbursement for incurred costs, and a clear plan for preventing further occurrences from the same parts already replaced on this nearly new unit or simply replacing the “design-defective” components with ones that are not defective, completely on Carrier’s dime.
