Hey, Not sure if you have chosen a system yet i would recommend a few things. Your situation would really dictate what kinda system to go for, and with the lack of detail about how or what you intend to grow remeber rule 1. KISS, keep it simple stupid. Drain to waste, soilless medium, pots ,hand watered. Diy hydro 101, it will get you in the habbit of mixing nutes, ph'in, ec measurements. Would recommend coco coir for the extra 'buffer' as it were. The buffer being that if something is off you will get some time to fix it before a loss in production. Leave the NFT, and DWC for later, as if your parts fail, loss in production very quickly. i killed some tomatoe clones in a home built NFT as i went with a new nute mix and it went bad, ever so quickly. Best o luck. bunnyface.

Hi Tiger,Ryan and Gary Happy 4th guys. Hope you're out there partying!! The Infinity system is running just great. Its so quiet inside the house that I can barely tell its on. I am so so happy with it. Its a real sweet baby. The temperature in Sacramento has been very nice these past two weeks, just in the 80's. Its kind of weird because last month we hit the 100's. I am confident though that this baby can handle it when we go back up to the 90's and 100's. As for the ducts Ryan, the flexi is attached to metal, but I don't know if its the insulated kind. But it is very quiet. I don't hear noise from the vents. I did take a peak into my attic from the ladder and the flexi is nicely layed out, no spagetti up there. Also all direct from the airhandler and no Ys. Well i've been partying all week Gary. I love this baby. But the real big party will be in the winter when its real cold outside and my living room will actually feel warm. For me that will be the biggest test because I can't handle the cold and like it very warm in the house. My old heat pump always blew in cool air when its below 45 degrees outside. If any of you will be in the Sacramento area in the future, let me know and we'll have an Infinity party or we can party Infinityly!! You guys take care and thanks again for all your help. I'll be travelling quite a bit on the job from mid July until late September, so if you post something and I don't get back to you please know that I'm on the road. Demi

Thanks again for your input. I think we've decided on a Trane. The Carrier our friend quoted was the base model 25HBC536A with FX4DNF037T and even at $3368 it'd be a few hundred more for permit and hurricane pad, which would make it close to the cost of the company who quoted 25HCC536 and 25HBC536 models. Also with our friend, we'd need to pay it all by check. we have the funds, but Carrier is offering zero percent for a year or so - minus well use thier money for a year! Both the Carrier Comfort and Trane XR15 seem comprable in function and effeciency, so then I had to decide which one looked better to me. That's a woman for ya! :) I'm going to try to get the company who quoted the 2 Carriers and the TRANE TWR536 with TEH3F4ZB $4150 to come down a few hundred and see if he'll include the $125 for the MERV 11 1 year filter. Is it common to ask for lower price on this type of service? The only company that even asked about our windows was the One Hour AC franchise that did the only load calculation. He factored our house needs 2.5 ton unit. We had the windows in a few months before the ac broke and there was not really a significant change in our electric bill. We did go from aluminum single pane 30 year old windows to impact laminated insulated glass vinyl windows. You could feel the heat coming in on the old - the new you can barely hear any outside noise and it's got a coating that helps block the solar gains. neohioheatpump - it's always hot here in Daytona! ;) I think we're only expected to not hit 90 today because it's raining.

If you can get a free connection to gas then that should be your fuel for heating. In most parts of the country it is cheaper to heat with gas than a heat pump. If you are curious post your electric and gas rates and we can do some comparisons on heating costs. The first quote does not make sense. If you are going with a gas furnace, then you should not need a new electrical panel. But you will need to run a 120v 15amp line to the attic, but it should not cost $1565. The gas furnace takes the place of the air handler. A gas furnace costs about the same as the equivalent model air handler. But you will have to run a gas line to the attic. So I don't understand why you need to pay an additional $2500 for the gas option. The Bryant quote has incomplete model numbers. The complete number would indicate the size. You also have no model number for the coil, or what filter will be provided. The Rheem quote seems more reasonable. It is difficult to judge how much of the quote is going towards installing duct work. Is the duct work insulated and if so how much insulation. Flexible duct work should be R6 or R8 rated unless your attic is insulated. Any change the equipment and duct work could be installed in the basement? It would be much better than installing in the attic. The sizes in the Rheem quote seem reasonable. It would be best if a load calculation were performed to confirm the sizes since you have no history other than radiant heating. I am glad to see that the Rheem contractor is proposing a 96% efficiency furnace for the attic. Do you go below freezing in the winter? If so heat tape will need to be installed so the condensate does not freeze. The Rheem quote needs the coil model and filter. I suggest getting a 4 inch media filter.
