Business ProfileforCarrier Corporation

I have purchased a Carrier Infinity system in 2019 and every year when there is any lighting around (even if there is no rain), we have to run to our circuit breakers to shut off the power to both our Carrier Infinity unity, otherwise the boards get destroyed! The unit was installed in May 2019, within 4 month we already had 2 service calls regarding the circuit board being blown, (Simple procedure 10 minutes to change out the board, seen it done already 5 times!) every year consistantly this happens! This year On October 1st at 5:12 PM, we had the same issue, the board is blown out again.When I called for service (ARS Tampa Bay/Rescue Rooter) even under warrenty the parts are covered, but the labor is what I am responsible for and I understood that. The Issue here is what they wanted to charge me. I was told that the parts are covered but the labor is for the 2 boards will be $1,850 for the labor, a ten minute job for each board, total of 20 minutes maximum! Is *** trying to re-coup for their loss of profit from my situation? Less than 30 minutes and I have already paid the technician $109, for his visit, and he said that payment has nothing to do with that $1,850 labor charge! We have two wrongs here: 1) Carrier is needed to be responsible for their products, is this a lemon product, is there a recall or newer upgraded unit due to this issue? Can't do this every year, it is very stressfull, I cant leave the home, no vacation, we have to baby sit our airconditioner every year or else! 2) *********/Rescue Rooter needs to stop overcharging customers, just because they can! (That's more than $3,600 per man hour!) Their technician even tried to contacvt their supervisors, I had 5 listed on my phone. the techsaid 3 has already left the company and the other 2 I can try to call, called but no reply, left messages. Seems as nobody wants to discuss their highly overpriced man hour prices with me.
