Dehumidifier Lifetime z z

We moved into our newly built house more than 12 years ago. It has a large poured concrete basement. We purchased a dehumidifier to lower the humidity in the summer months. We have replaced this humidifier by sending it to the county landfill 8 times in the 12 year period. Most of the time we had 2 dehumidifiers running at a time so the lifetime is more than 2 years even though the failure rate is less than 2 years. However, I am planting 1 dehumidifier in the landfill every 1.5 years and they are not a perennial but an annual.

Without fail I have explored more than one repair facility at every failure and I was told, with out fail, that it is much less expensive to replace than repair.

It would seem to me that dumping 8 dehumidifiers in the landfill has a worse impact on the environment than recharging the coolant gas. Perhaps there is some compromise legislation which would ban dumping large quantities of dehumidifiers into the landfills and requiring the manufacturers of dehumidifiers to make it easy to replace the coolant gas.

After all, I have already dumped my load into the atmosphere when the dehumidifier has failed. I can't believe that dumping the rest into the landfill somehow balances out. Perhaps the air quality brand of the EPA needs to interact with the water quality branch of the EPA. If they would like I could give them an address and phone number for each.

Maybe you need to address the cause of the wetness. Here is my list on the best means to address this:

Make sure your downspouts have a pipe that collects the water and sends it as far away from your foundation as possible (downhill). If you don't have gutters I would put them on to collect the water.

Pull away the dirt around your foundation walls (the lower you can go the better) Be careful here as you don't want to cause the foundation to shift if you have stone or rubble walls. If you can get to the top of the footing thats ideal. Then get water emulsified tar (only sold during the warm months) with a brush and/or roller paint the foundation walls on the outside with a good coating. Once it has dried go over it again this time while its wet put 2x4 foot Styrofoam sheets against it (gluing the sheets to the wall) make sure to butt up the seams tightly and make sure you don't go above the soil line as you don't want the tar or the Styrofoam visible.

If you can't get to the outside walls you can try sealing the inside walls with hydraulic paint to prevent the moisture in the concrete to enter the living space.

The last issue is the floor. Here you will need to see if the drainage is adequate. Locate the lowest point the house sits this is the ideal placement for a sump pump as you want the water to collect at the point you can discharge it away from the foundation. If you do get a lot of water you may need to look at using injecting grout along the hill side wall to reduce the water going under (moving it away). If you can't do that you may also find using a hydraulic floor paint can help.

Lastly, try to create as much ventilation as you can. The only problem with this is in the winter time and humid days this won't help. We're back into needing a dehumidifier. But maybe with the other stuff fixed you won't need it as much so it will last longer.

All you say may be true, but there are still many cases where a dehumidifier is needed (not just basements, but whole houses in humid spots like Florida).

The fact is I had 2 dehumidifiers that lasted 20 and 7 years respectively and did their jobs, but my last 5 have each lasted 11-16 months each, all freezing over in the end despite being perfectly clean and above 65 degrees.

Not sure what the solution is but IMO if the environment is a real concern we need mandates that these things being serviceable and not continually dumped (or even hopefully recycled). I had 2 Vremi 50 pint units that each lasted 11 months, first replaced by Vremi factory warranty (didn't take back the old one), second one given a refund by Amazon extended warranty.

They are mostly idle 6 months a year and I use the bucket and only empty every 2-5 days so it isn't even like I'm running them near maximum duty.

My older Perfect Aire unit seems junky but has been running for 7 years with a direct drain in the same space.


@Bruce Chapman - I wasn't discounting the need for a dehumidifier in humid climates like yours.

The first direction is preventing ground moisture from entering your home as that's the largest source, Then you have less work to get rid of whats left in the air. But even that is still not addressing the seepage though your walls. That gets into tightening things and installing a vapor barrier if you can.

The tighter you are the less dehumidification you need, which in turn reduces the costs of the equipment and power to run it.

The amount of moisture you are removing 'a bucket every 2-5 days' to me seems like a lot!

This has been an ongoing problem ever since the EPA forced switch to 410A which operates at a higher pressure and is less efficient than the prior refrigerant R -22. Another example of government inefficiency in its well-intentioned, but mis-applied solutions to environmental problems. There is nothing wrong with

Dan's solutions, but they don't deal with the real basement problems caused by lower basement temperatures and high outside humidity. Older R-22 dehumidifiers lasted longer. We had a Westinghouse that lasted 20 years, which we unfortunately gave away because it was too noisy. Current ones last about a year, so it is worthwhile to get a contract on them as it will always payoff.
