Most of what we are called out to could have been caught earlier, and a fair share of it could have been avoided entirely. Dryer vents pack with lint until the machine runs hot and slow. Condenser coils blanket over until a refrigerator never stops running. Dishwasher filters load until the wash water stops arriving where it should. Washer inlet hoses age out quietly and then fail all at once, usually while nobody is home.
A maintenance visit covers those jobs properly and tells you honestly what does not need doing. We check and clear the dryer vent run, clean condenser coils, service filters, inspect door seals and gaskets, look over water hoses and connections for age and damage, and confirm each appliance is level and stable. Where something is close to the end of its service life, you hear it as a heads-up rather than a sales pitch.
