How much does an HVAC filter cost to replace?
Updated
Short answer
Replacing the HVAC filter yourself costs $5 to $50, which is the price of the filter. A technician's service call to change one runs $75 to $150, and almost nobody pays it, because the job takes 5 to 10 minutes and no tools. The price of the filter itself depends on its size, its thickness and how fine it filters, and that's the only cost there is.
Cost breakdown
| Item | DIY | Pro |
|---|---|---|
| Materials | $5 to $50 | included |
| Tools you may need to buy | none | included |
| Labor | your time | $75 to $150 |
| Total | $5 to $50 | $75 to $150 |
The whole DIY cost is the filter. At the low end is a thin fiberglass or basic pleated filter in a common size. At the high end is a thick media filter for a filter cabinet, which costs more per filter and lasts far longer, so it's cheaper over a year.
What drives the cost
- Thickness. A 4 or 5 inch media filter costs several times what a thin one does, but it goes every 6 to 12 months instead of every 1 to 3, so the yearly spend is similar or lower.
- Filtration rating. Finer filters that catch smoke and allergens cost more than basic dust filters. Pick the rating the system's manual allows, since too fine a filter restricts airflow.
- Size. Common sizes are cheap and stocked everywhere. An odd size costs more and may need ordering.
- Buying in bulk. A multi-pack of the right size, bought once a year, brings the per-filter price to the bottom of the range.
- Changing it on schedule. A filter that's left in too long costs more in energy and wear than every filter you'd have bought.
DIY vs. pro
This is the job to do yourself, without exception. Knowing how often to change your HVAC filter and keeping a spare on the shelf is the entire skill. The slot is at the return grille or beside the air handler, the old filter shows the size and the arrow direction, and the new one slides in the same way.
The only time a pro changes the filter is during a tune-up, where it's part of the visit and not a separate charge. Paying $75 to $150 for a service call to change a filter alone buys years of filters. If you can't find the filter slot, ask the technician to show you at the next tune-up rather than booking a call for it.
FAQ
How much should an HVAC filter cost?
$5 to $50, depending on size, thickness and filtration rating. A thin basic filter is at the low end and a thick media filter at the high end.
Are expensive HVAC filters worth it?
A thick media filter is, since it lasts every 6 to 12 months and catches more. A thin filter with a very fine rating often isn't, because it restricts airflow and clogs fast.
Does a technician charge to change the filter?
Not during a tune-up, where it's included. A separate service call for a filter runs $75 to $150 and isn't worth it.
How can I spend less on HVAC filters?
Buy a multi-pack of the right size once a year, or switch to a media filter cabinet if the system allows it, which costs more per filter and less per year.
