accumulate dust and need regular inspection and cleaning.

Yes, you can, but you run the risk of expensive repairs if your AC
unit breaks down. Additionally, dirty AC units are a breeding ground
for bacteria due to the build-up of dirt and greasy substances.
Can a dirty filter stop AC from working?
A dirty filter restricts airflow through the air conditioning
system, which causes strain on the air handler fan motor. If the
dirty filter is not cleaned, it will cause the fan to overheat,
which leads to a breakdown.
What are the signs of a dirty air filter?
Dirty air filters lead to unclean air supply and reduce the system's
efficiency of cooling the house. You can visually notice a clogged
air filter. Also, if the system is not cooling the house, it could
