Maybe I could wrap a heating cable around it, the kind they sell for water pipes so they won't freeze.
I don't know if that would have enough power, the one I saw online uses only 36 watts.

When I'm indoors I use an airline respirator that pumps air through a hose from the outside to a facemask I wear. The hose is 50' long, but in the NY State winter the length won't be enough to warm...

Sure, I get it maintained by the people who installed it. But cleanings in between their visits are also needed. A surprising amount of fuzz gets through the filters (which yes, I do clean).
My...

I have a fujitsu minisplit AC. The fan in the indoor unit gets all gunked up. Stuff gets through the filters and into the fan. Probably of canine origin :)

So I'm thinking of buying an air...

A heat pump water heater can exhaust cool air to an indoors space. I guess it's using a much less powerful heat pump.

Huh.
Would it make sense, I wonder, to have a heat pump pulling heat from my garage? My garage is in the lower floor of my house. It's warmer than the outside because of heat leaking through the...

I got a Fujitsu minisplit heat pump last summer. I meant it for AC.
But I was startled to find the thing is going to pay for itself quickly in savings on my heating bills!!!
I live in NY state. ...

Does anybody have COP data for different temperatures for some minisplit that's a similar size to mine? Mine is about 1.25 ton.

Probably all these minisplit heat pumps have very similar COP. ...

I asked Fujitsu, somebody there called Mike, for the COP of my 15RLQ heat pump. He said max 1.54. But it's "rated heating" was 3.07. He said the "rated heating" is a COP in ideal conditions in the...

Metal venting, "spark ignition". 24 years old. Says "efficiency 82.9% A.F.U.E." When it was new.

I don't know. But it's old so it's probably not very efficient.

For the heat pump, the manual gives the "temperature range" for heating mode as 5 to 75F.

So you're telling me the heat pump...

I live in New York state. It gets down to 0F often and sometimes colder in the winter.
The electricity is 13.5 cents/kwh here, and natural gas is $1.66/therm.
I have a Fujitsu 15RLQ minisplit....

I had a Fujitsu minisplit heat pump installed. I also have forced-air gas heat.
Below some temperature, from what I understand, it'll cost more to have the heat pump helping to heat the house,...

Hi, I posted a lot of questions here about AC, and I've gotten my minisplit installed. I'm happy with it. And thanks to all the people who responded to my questions!
I have 660 sq ft of upper...

Is there a whole house dehumidifier with an inverter compressor? It would run at a low level a lot of the time, thus helping with noise issues?

It seems like inverter compressors are the future...

I have a forced air gas heater, and I've wondered if, when the fan is on, some of the air gets ventilated out to the outdoors. Would this never happen? The only ventilation in it is probably...

I talked to Fujitsu and they said they have a minimum length for refrigerant lines to avoid refrigerant flow noise, and the bedroom is far enough from the outdoor unit so that I wouldn't be hearing...

There are lots of ways of doing it. This is just what he came up with.

I suppose you don't have to locate the outside unit right next to the house, even.



Sure. So it's feasible to...

How loud of a whoosh? Kind of hard to describe, probably. Whooshes are relatively un-irritating, but introducing any kind of noise into the sleeping area isn't good. I'd probably run it in dry...

I don't have it installed yet. I had a contractor over to look at how to install a mini-split and that was his suggestion, have the lines run the length of the house since I wanted the outdoor unit...

does refrigerant ever make noise going through the lines, like gurgles etc.? It looks like the refrigerant lines for my mini split might run through the bedroom suspended ceiling.
Laura

I was talking with a local contractor and he said he liked LG mini splits. Since these weren't mentioned to me as good brands when I asked here, do you think they're similar in quality to...

People are more likely to see it if it's its own thread. I can reword it to make it more a standalone post if you like.
Laura

Seems about right. This person didn't like Fujitsu as much, but maybe it's just a dislike of lighter plastic, he said the condensate tray for instance was lighter plastic. Light plastic doesn't...
