My old HVAC system, I used a separate thin filter installed on my cold air return vent from ACE and I changed it every 3 months.
I can buy one and get one free on sale at aprrox. $3.50 a filter.
Carrier HVAC filter sell for $50.00 and $80.00 on Amazon.
My question is, should keep using the ACE filter or the one on the unit itself? 
Using the thinner standard filter, will it effect the warranty?
I was told not to use both filters from the installer at the same time.
Of course, the Carrier dealer said the filter that came with it is much better filter.
What would you do? |
This is really pretty simple. The real question is "Do you know more than the engineers at Carrier who designed the system"? The engineers have 2 goals, design a system that does the job, and that lasts as long as possible to minimize warranty. They designed the filter to accomplish this. You can get 2 for $70, which is $35 a year. You live in The Villages so I know you can afford that. They have done a lot of testing. Trust them.
I do the same thing with my cars. I do exactly the maintenance in the book, nothing more, nothing less. My last 4 GM cars have lasted well over 250,000 miles, and I have very few problems. Its not perfect, but you will never have the test data the engineers have, they run all this stuff to failure hundreds of times.
