Most Neglected Home Maintenance Item

Services for Real Estate Pros with Bluegrass Homes & Farms Realty, Agent Know How

My husband works in HVAC doing maintenance, and this is a pet peeve of his. Change your filter regularly and enjoy cost savings, breathe easier, AND have a longer life to your system! Most filters do not cost that much; just replace them every 3-6 months, or more often if you have pets or allergies.

Most Neglected Home Maintenance


Greetings! Ryan Bruzan here. One of the most neglected home maintenance items, in the humblest of my experienced opinions, is changing the air filter(s) in the furnace. The commonly stated rule is to change the filter once per month, but depending on the season and the type of filter, that rule does not necessarily apply. With the variety of filters out there, it is important to understand the working conditions of the type of filter chosen. Some filters have instructions and important useful information on the packaging.

The following paragraphs are simply my own observations as a homeowner.


Over the years I have tried a variety of filters for a variety of reasons: price, brand, review, experienced usage, energy bill, my own home energy research, respiratory conditions, asthma... I am certain there were other reasons.

The type of filter you will choose depends on your situation. While shopping at a home center for a filter, take a moment to review the information and explore your options. 


Air FlowVERY IMPORTANT: PAY ATTENTION TO THE AIR FLOW AND THE ARROWS ON THE FILTER. If you look at the filter, there is some type of protective screen on one side. The purpose of that screen is to prevent a filter heavily accumulated with dust and debris from begin sucked into the fan, which could stop the fan and burn up the motor, especially if it is not equiped with heavily accumulated filter auto-shutoff switch, a.k.a. HAFASS (I just made up that switch :)

The more porous the filter (like the green filter shown), the greater the airflow, the longer the life of the filter because it doesn't collect micro particles. A micro particle filter, on the other hand, will collect much more particulate matter. Such collection will build at a much faster rate than more porous filter. As the filter collects dust, it clogs the fine pours of the filter. This causes the fan in the system to work harder increasing wear and tear. Additionally, buildup begins to diminish the airflow causing the unit to work longer and harder to produce the results required by your thermostat settings. What happpens when anything has to work longer and harder? It heats up, gets hotter!Air Filter Screens

In hot, summer months most air conditioning system failures occur as a result of neglecting to change the filter(s); it is that simple. A tight financial situation should NOT deter you from changing your filters. The added costs of everything else that could need to be done is well worth this particular expense. I have learned some valuable lessons.


Lesson One: Filters are cheaper than repairs.

Lesson Two: A/C repairs are like buying new cars. Once you buy a new car and drive it off the lot, you realize that you are not the only one driving that type, style and color car.

Lesson Three: "A service technician should contact you withing 24-48 hours." WHAT!!! DO YOU KNOW HOW HOT IT IS OUTSIDE?!

Lesson Four: Wait.

Lesson Five: Be patient.

Lesson Six: Stay hydrated.

Lesson Seven:  Play in the sprinkler.

Good Day!

This is a great blog.  I will pass it on to our son, who is an HVAC guy.  Every time I mention changing the filters, he says to me that he will come back tomorrow with his ladder and change it out for us.  Every time, I wait a week or two and change it myself.  You know, the cobbler's children never had shoes.  lol

We have pets and we're a once a month family from March to October and every two months for those other 4 months because we primarily heat with our wood burning stove and use the furnance very very little.

Jean, you made me laugh! I can sympathize. Although we have a wonderful new Trane heat pump that hubby installed, he knows how to do just about anything and chooses not to sometimes. :)

Tammy, we change ours about every 1-2 months because we have a cat. A home with a wood burning stove on a lake in Georgia sounds DIVINE!! I am picturing a happy Christmas by the fire!
