That's only the initial capex though. $5,000 is a realistic swag for install + lifetime electricity + minor system maintenance.

- bradlys 1y agoThese fans are not using $3000 in electricity over their lifetime.
- zamadatix 1y agoI guess that depends how old you are when you install it and how long you plan to live but ~$7 per month is not at all an unrealistic electricity usage estimate for the system. 7*12*35 = $2,940. Edit: E.g. the numbers from this site suggest, for 15 out of the 16 listed fan models, the lifetime electricity cost is likely to be significantly larger than the install cost unless you are already much older at the time you start using the system or you have extremely cheap electricity (or both) https://www.radonaway.com/radon-fan-operating-cost-calculator https://www.radonaway.com/radon-fan-operating-cost-calculato...
- dgfitz 1y agoThis point always amuses me. Thats like, 1 starbucks coffee a month, or 1 trip to a fast food place a month, or one extra thing at the grocery store a month, or half a movie ticket a month, or half a streaming service a month, or less than half an LLM subscription a month, I could go on for a while. For the cost, preventing cancer seems like it's a wise investment. I say this as a cancer survivor.
- Waterluvian 1y agoBut it doesn’t prevent cancer. It lowers the risk of a specific kind of cancer by some amount. Is it $650 worth? That’s what I’m stuck on. People just go by vibe and say things like “it’s a good investment” but that’s just coming from I don’t know where.
- maxbond 1y agoHow much does it really have to prevent one of the most painful and expensive forms of cancer, not just for you but also your family, to justify $7/mo? Not very much, in my book.
- yunwal 1y agoSame comment as the one above. There are literally infinite things you can do to reduce your risk of mortality. This would have to be among the best options if those things.
- maxbond 1y agoIf you have a radon test indicating there's a problem, then it is no longer theoretical. There aren't an infinite number of pressing and known risks. I think it's a mistake to conflate an infinite number of hypothetical risks with a definite and known risk. It leads to analysis paralysis and FUD. It is not possible to know what, among all of the infinite hypothetical options, is the best to reduce your mortality. So let's focus on the concrete steps we can take and that we do know are effective. For most people, that is not radon mitigation, because most people don't have a radon problem. If you find out that it is a problem for you, and you have the cash to solve it - just solve it. It's that simple.
- dgfitz 1y agoI'm just saying, I'm happy to pay for our system at the cost of seven whole dollars in energy cost per month, for my spouse and kids if nothing else. If in 20 years I find out I got ripped off, I won't really be upset about it.
- Spooky23 1y agoIt’s a risk/reward. For a nominal cost, you essentially eliminate a gas that causes or accelerates lung cancer. Enjoy one free beer a month, dude. Chances are you won’t develop a vicious cancer.

- zamadatix 1y agoIt amuses me but maybe for the exact opposite reason: Phrase it to the median person as "for just a quarter per day" (queue sad music on a commercial) and we'll be worried about everything but the cost because it seems too low to think about. Say "For just 1 of less than 500 such choices you can afford to make in your lifetime" and suddenly we start wondering if it's something that makes the cut. Of course that's median, most people on HN... probably should just get the system if the Radon levels are high.
- dgfitz 1y agoI read this 3 times, I have no idea what point you’re trying to make here.
- maxbond 1y agoThe present value of $7 in 35 years is $1.45, assuming a risk free rate of 4.5%. Paying $2940 over 35 years is much more affordable than paying $2940 up front. If the goal is to be rational about risk, let's right-size the numbers. Otherwise our figures will be misleading.
- kevin_thibedeau 1y agoYou're not going to spend a fixed price over time. You're going to consume a fixed amount of energy and pay an increasing rate as the dollar inflates.
- maxbond 1y agoIdeally we'd model all relevant parameters, my main point is that presenting the cost as $2940 is misleading.
- yunwal 1y agoAnd their point was that it’s not. The price of electricity typically grows to offset inflation.
- maxbond 1y agoThe time value of money is typically a more significant factor than inflation. If you believe that there will be massive inflation that outstrips the time value of money, then you should still feel this figure is misleading because it's too low.
- zamadatix 1y agoI agree it's best to consider the capex/opex separately but I strongly disagree taking this approach will right-size the number. Here you're taking lifetime opex in nominal dollars but still devaluing it based on inflation anyways, which will not give you a meaningful result.

- ProAm 1y agoThat is still insanely high. The highest Ive seen for install is $650 but required quite a bit of piping to the exterior.
- irrational 1y agoJust the materials cost was $500. How are they doing labor for $150?
- adamsiem 1y agoAnd heating/cooling the fresh air replacing evacuated air + radon.
- irrational 1y agoThe air is under your slab. How would it be replaced by fresh air inside the house?
