The Ultimate Guide to Maintaining and Replacing Your Home Appliances and HVAC

Table of Contents


I just finished a long chat with our washing machine repair technician, and what I learned should be shared with the world. 


"They don't make them like they used to."

Home appliances are no longer built to last. Our repair technician took the time to investigate because, when he started the job, he was aghast by the average age of the appliances he was hired to fix. The most expensive home appliances might have the coolest features, but even those are not built to last. 


If you're wondering whether we need to buy a new washing machine, we do. We are taking the advice of our repair technician on what to purchase based on what he sees in the field. 


How to Determine if a New Appliance is Needed


Is Your Appliance Under Warranty?


Check the owner's manual to see if your appliance is still under warranty, in which case repairs may be covered for the first year or two. Check with your home warranty provider to see if it will cover the repair cost or the cost of a new appliance.


How Old is Your Appliance?


The average lifespan for appliances is a good reference point, but remember that it can vary depending on maintenance and usage. If you have recurring problems, you should consider replacing a newer appliance sooner.

Communication with Your Spouse


Conversations about spending upward of $1,000 on a new washer are the opposite of fun. My goal is to relieve my wife of undue stress, such as figuring out what to buy and the installation logistics.


When the repair technician delivered the bad news, my wife was out of the state on business. I took responsibility for managing the issue, which included eliminating the mental load for my wife. 


I did not bother her with a phone call. I emailed my wife the bad news on her personal email and shared the two replacement options. I did this so she didn't have to take the time to research it herself. 


I then told her I would take care of purchasing the washer she wanted and scheduling the repair technician around my schedule. 


How to Extend the Lifespan of Your Appliances and HVAC


How to Extend the Lifespan of a Central Air Conditioner
