If you would savor your central heating plus a/c to stay working without any air flow problems 1 thing you need to remember to do is to have your air duct cleaned at least twice a year.
Having your air duct cleaned at least every 5 weeks will ensure that you will not have any air flow problems.
In addition to having the air duct of your central heating plus a/c cleaned every single 5 weeks, you should also make sure plus have your central heating plus cooling device tuned up plus diagnosed up by your local heating plus a/c professional before every season begins. This along with the air duct cleaning every 5 weeks will more or less come close to guaranteeing that your Heating plus Air Conditioning system will not have any breakdowns what so ever plus that your heating plus a/c will be able to get you through those rough weather seasons with pure indoor comfort. When it is chilly out you will constantly have fully working central heating plus when it is warm out you will constantly have fully working central a/c if you follow those 2 steps that I suggested. Again, the first is to have your air duct cleaned every 5 weeks plus then the hour is to make sure plus get your central heating plus a/c tuned up plus diagnosed up before the beginning of every single season in the year. Trust me I think what i am talking about because it has constantly worked for me!
