Hello I'm considering the purchase of a house with a barn. The barn is in central Ct. It was once part of an 80 acre farm used for raising cattle for beef. The barn has a plywood floor. I asked if there was concrete under the floor and he said no, it is a double 3/4" plywood floor on 2x 12 wood...

I have a question for the Architectures on the forum. I'm building a new house and will be working with modified plans. One of the areas I need to modify is the ceiling height in the garage to install lifts in. The stock plans have 10' walls in the garage so I would like to raise the central...

Hello everyone. I just purchased a piece of property to build my new House/Man cave on. The property is 2.5 acres of which about 1.5 acres is usable. I would like to put the septic field in a area not useful for anything else. So I am thinking the bottom left corner of the property. That is a...

I got kind of sick of using cheep come-alongs to winch up disabled vehicles onto my 4 post lift. So I came up with this quick to install boat winch idea which works pretty good on the bend pak HD9 4 post lift. I'm sure a variation could be made for other lifts. In any case my biggest problem...

Like the questions says Can a 200 amp sub panel be attached to a 200 amp main panel. In this case the house would already be equipped with a 200 amp service but I would want to run a 200 amp sub-panel to the attached garage. Possibly upgrade to 400 amps at the main house at a later date.

As life would have it my daughter is getting married and I am that one oddball person that will have to retire up north to CT to keep the other half happy.

I just purchased a ceiling fan for my shop. I read a section in the NEC 314.16(B)(1) exception for ceiling fans. I believe it states that I do not have to count conductors in a box for volume calculations if I use up to 4 #16's or smaller. So I would like to use #16 so I can fit everything into...

Hello I have recently purchased a Lincoln Power MIG 210 welder. So far this has only happened twice but it happened on two different 120V circuits not connected to the 240V welding circuit. My welder is feed by a 110 AMP sub panel off the main 200 AMP panel. I have two separate 120V lines that...

I am interested in running 240V to my lathe and splitting off 120 to an additional duplex receptacle to run accessories. There are safety switches and main lugs as shown below. In this scenario I would need to put two wires into each load terminal screw. I remember having a home inspector...

I have a Goodman ASPT47D14AA air handler connected to GSZ160421BB condensing unit for a heat pump. This is a matched set. The directions for the condensing unit say that if it has a non adjustable TXV, it needs to be charged using the sub cooling method only. But no where in the air handler book...

Dose this look right? Specifications for my new Goodman air handler call for a 20 x 24" filter. Then it says 20 x 23.5" minimum. The attached picture shows how a 20 x 24" filter fits. I have to bend it to get it to fit. I think 20 x 23.5 would be perfect but I cant find one. In any case I am...

I while back I posted a question about the pros and cons of the old Transformer style Lincoln Square wave 175 verses the new Inverter style Square wave 200. I didn't get any direct comparisons for the two machines. But I have since traded in my old SW 175 and picked up the new SW 200. So far I...

I was having difficulty balancing out my heating system. The room with registers closest to the air handler were having some flow issues. I was measuring airflow with an anemometer type instrument shown. All of the registers had zero flow at the leading edge of the duct opening. The last three I...

First day I have really cool 35° outdoor temperatures to run my new heat pump. I turned it on with an indoor temp of 51°. The temp got up to about 62° and the compressor turned off for about 30 sec. About 5 min later it turned off again and then back on in about 30 sec. So far 10 min later it...

Hello I just put in a heat pump system and am very happy with the way it works with on exception. The thermostat I have Pro1 721 will turn on the heating coils at 2 x the swing temperature setting which is limited to at most 2° meaning my coils will come on until at most 4° of set point. Since...

I have a question about the wiring diagrams that came with my system. There appears to be inconsistency between the three pieces involved mainly on the W2 vs W1 terminal. System Goodman 3.5 Ton 16 SEER R410A Complete Split System Heat Pump Condensing unit GSZ160421 Air Handler ASPT47D14...

Hopefully tomorrow I will be brazing in my new heat pump. My question is can I purge by passing Nitrogen from the condenser high side through the expansion valve and back through the low side line or the reverse. Another words will the expansion valve be open and allow this to happen. If not...

I have a question on mounting the condensing unit for my 3.5 ton Goodman heat pump. There doesn't seam to be any access to holes on the bottom of the unit without taking apart the whole thing and drilling. nor does it appear that the pad I have has holes in it to mount to the concrete but I...
