It was definitely worth it! We also noticed that the heating became less efficient and started paying more, but did not change anything. We contacted duct cleaning vaughan from httрs://comfortclean.com/air-duct-cleaning-vaughan/ , and it turned out that the air ducts were completely clogged, which prevented normal air flow. After cleaning, the system began to work like new, and heating bills decreased. So yes, if you notice such problems, it is better to start with cleaning.
