I first noticed it when another energy bill arrived
At first, I didn't think much of it.
One month, my energy bill was a little higher than I expected. Then another bill arrived, and it was higher again.
Every month, it felt like I was paying more just to keep my home comfortable. I started mentally running through all the usual explanations.
Was I setting the thermostat too low? Were energy rates increasing? Was the weather causing my system to run longer? Was someone leaving the lights on?
I couldn't find one obvious answer.
But every time another bill arrived, I had the same frustrating thought: Where is all this money going?
I felt like I was doing everything right
I wasn't leaving the windows open while the air conditioner was running.
I wasn't constantly changing the thermostat, and I hadn't added any new appliances that could explain the difference.
From what I could see, nothing inside my home had changed. I also pride myself in having a relatively clean home.
That was the frustrating part. The higher energy bill was right in front of me, but the reason behind it wasn't.
I began wondering whether something inside my home was causing my HVAC system to work harder than it needed to.
The problem wasn't my thermostat
At first, I assumed the problem had to be the thermostat, the weather or the amount of electricity we were using.
But the real problem I found from reading forums online.
Checking the HVAC air filter.
When I stopped and tried to remember the last time I had changed mine, I honestly couldn't.
So I found the filter, carefully pulled it out and immediately realized how badly I had overlooked it.
It wasn't just slightly dusty. It was completely covered in buildup.
Then everything started to make sense
An HVAC system needs proper airflow to move heated or cooled air throughout a home.
As an air filter captures dust and other airborne particles, it gradually becomes dirtier. When it becomes heavily clogged, it can restrict airflow and cause the HVAC system to work harder.
I couldn't say that the dirty filter explained every change in my energy bill. Weather, energy rates, insulation, thermostat settings and household usage can all affect energy costs.
But I knew I didn't want my HVAC system fighting against a filter that should have been replaced.
I couldn't believe something so simple had been sitting inside my home the entire time.
That's when I found FilterHome
Once I saw the condition of my old filter, I knew I needed to replace it.
The problem was that I didn't know which replacement to order.
There were different sizes, different MERV ratings and more options than I expected. I didn't want to guess and end up buying a filter that didn't fit my system.
While searching for the correct replacement, I found FilterHome.
FilterHome makes HVAC air filters on Long Island and offers multiple sizes and filtration levels for different homes.
I checked the size printed along the edge of my old filter, matched it with the correct replacement and selected the filtration level that made sense for my home.
The biggest change was finally knowing it was handled
After replacing the old filter, I knew my HVAC system was no longer trying to pull air through all that buildup.
Changing one air filter doesn't guarantee a specific reduction in an energy bill. Every home and HVAC system is different.
But I had finally stopped overlooking a basic maintenance task that could restrict airflow and make my system work harder.
I also realized that buying the filter wasn't the difficult part. Remembering to replace it was.
Now, instead of waiting until another high energy bill makes me question everything again, checking my filter is part of my regular home-maintenance routine.
Before your next energy bill arrives, check yours
Find your HVAC air filter, carefully remove it and inspect its condition.
Then look for the size printed along the edge of the frame. It will usually look something like 16 × 20 × 1, 20 × 20 × 1 or 20 × 25 × 1.
Your air filter may not explain every dollar on your energy bill, but making sure your HVAC system isn't struggling against a clogged filter is an easy place to start.
