Thanks Teddy Bear. Took me a while to digest everything
1) Should I keep 2nd Fl windows closed even if the AC isn't operational during the day? Then maybe turn on an hour prior to sleep time?
2) My...
1st floor AC is located in basement and 2nd floor is located in attic. The attic one actually has 2 return ducts as a HVAC contractor through there's not enough movement of air. Once he did that,...
Yes I’ll do air sealing for sure. Do you think blowing in insulation will also help? Another poster said he only saw 1 degree of difference. Thanks
Can you explain this in another way, I’m not sure I fully understand and don’t want to guess
Thanks, this is a pretty marginal difference indeed
Is the attic considered high pressure and hot air will find its way through nooks and crannies in this old 100 yr stucco house into the 2nd floor thanks
Guys - not exactly a HVAC discussion but rather about air patterns. If hot air moves up, does a hot attic have the ability to warm up the 2nd floor in the summer - think NYC in the 90's during the...
Guys - before I do upgrades, is there any setting on the Luxaire Unitary air blower where I can reduce the fan setting to the lowest possible to see if that makes a difference to the constant...
So by a standard 1.5 ton system, would this somewhat fit what you are thinking of and will be compatible with my furnace in the 1st thread
Goodman 1.5 Ton 15.2 SEER2 Heat Pump System w/2 Ton A/H...
So I'm assuming you believe cycle on/off is due to the oversized 3.5 ton unit currently? Also I can't find a 1 ton air handler and condenser anywhere
Won't a 1-stage air handler cycle on/off frequently as my current air handler does?
link got taken out so something like this. Obviously this unit also does heating but I'll continue using my old Luxaire Unitary furnace for heating (assuming it can be configured in that fashion)...
Something like this? https:/
I guess I can't reutilize the A-coil or the outdoor condenser and simply go with these 2 units correct?
Guys - did some reading as you suggested; most installers would recommend against condensing furnaces in the attic so I'm just going to keep it as-is for now. We just have pink batts insulation in...
Don’t think of that but why should that be a problem if I will have two pvc pipes going out the sidewall?
Here is a good man 30k BTU furnace - https://
Maybe I’m confusing terms and I confused others but my goal here is to never use electric for heating. Obviously cooking will be electric. So a 3 ton a-coil paired with a 1 or 2 ton - won’t that be...
Can anybody help answer no1-3 questions taking into account ELECTRIC IS NOT AN OPTION FOR ME, again in bold ELECTRIC ISN’T AN OPTION FOR ME
I’m not touching the basement unit as that was upgraded 2 yea ago. Heat pump was the first install in the basement and cost me $\ in an electric bill and we immediately swapped it out
If you can...
Guys - I'm upgrading my attic HVAC units (furnace, a-coil) for about 700sq ft space since it covers only the 2nd floor. It's oversized right now but moving to either 30k or 40k BTU furnace & A-Coil...
Well tree pollen season is over so I don’t need it running anymore. All my windows are open. During tree pollen season, I felt the unit was helping except for the real peak days with very high pollen...
Quick question - the Compact 70H has 2 filters - a black pre-filter and then a merv11/13 filter. Can I simply run it with just the black pre-filter or that'll reduce the longevity of the machine?
Guys - I have an older HVAC system that still works well for heating & cooling but on the thermostat when I do Fan ON, it doesn't come on and used to before. What could be the issue? I turned on the...
55-65 outside and 68 indoors and it’s a condenser. This unit doesn’t do anything in the winter time. I’m not sure if they needed to add more refrigerant or not. What does kind of sound typically...
All of the work was done by a licensed contractor and yes the refrigerant was collected and then put back in. Electrical too. Basically we moved the unit 20ft out
Guys - I had to disconnect and reconnect this Bosch condenser to do some waterproofing work and now it’s making some noise even though my thermost
is only set to heat which is furnace based. I...
So we are in the heart of the tree pollen season and although the dehumidifier has helped a bit, it's not fully eradicated the problem. It's possible Merv 13 isn't cutting it since it only filters...
Folks - not exactly hvac but I think similar principles apply so hoping you guys have an answer. Do you think it’s ok to have an air purifier like the blueair 400 lie on its side
Thanks
is it cool to spray paint the 8" duct going out white to make it less visible? The metal makes our home look too industrial from the outside. If you can recommend what kind of paint I should use,...

My installer cannot find the wind mesh with smaller holes. Can you suggest a material I can buy myself and make this. He said he wasn’t worked with this goose configuration...
I'm the same - I look for mid-priced, not cheap because I've been 'had' may times by expensive reputed contractors. One was recommended 6 years ago by a reputed architect I know personally and used...
Let's please stop pretending HVAC can be done the proper way because the circumstances, lack of professionals available to homeowners, etc. all contribute to this problem in NYC and other parts of...
guys - if any of you are willing to travel down to NYC to help me size a unit, please let me know and I'll pay whatever fair wage you decide on. As for finding somebody to do load, etc here, it's...
Can somebody post a link to a 1 ton condenser/a-coil with a high SEER rating. Also, I've decided to stick with a gas furnace - not going through electric and I know what my electric bills are - they...
Guys - electric rates here in NYC are 44c/kwh (am I correct this is region 4). Actually it's 750 sq ft taking into account the hallway between the bedrooms Also the rough calculations for HVAC...
Guys - I'm upgrading my attic HVAC units (furnace, a-coil) for about 700sq ft space since it covers only the 2nd floor. It's oversized right now but moving to 40k BTU furnace & 1.5 ton A-Coil for...
Is it possible to validate or cross check my 20% guess with this additional data (I did hvac system off during this test)
63 at supply register on 1st floor
60 at indoor air intake since basement...
Unit is in! Currently just placing a tissue paper by both ducts, I think I’m getting 20% from fresh air but once he installs a damper on the indoor return I’m going to adjust to get a good 50/50 mix....
So should I do insulation on just the external portion of the fresh air duct or the whole duct?
Also while I was opening the ceiling 15 inches around the basement perimeter to allow far future...
Do I possibly need motorized dampers for this? I only plan to adjust a few times a year so guessing a manual damper should work correct?
Thanks
My HVAC engineer doesn't think insulation is required for the fresh air duct since it's just passing air and his experience has shown it doesn't help much. Is that accurate?
Also what is the tool...
One more just brainstorming with the HVAC tech - to eliminate all the elbows we can use flex duct at some parts and solid duct for other parts. Do you think that'll work better to keep resistance low?
I finally found a good place to mount it so supply duct is only 8ft away. Fresh air return is roughly 10ft but it would include 2 45 and 2 elbows which is still quite a bit. Is it ok to use this duct...
We are still struggling to find an appropriate place to route the 8 inch duct. Is it OK to run this duct through the main supply trunk or that's a big no no
ok, the hvac tech just visited and he did research on my unit before coming which is nice.
1) For the fresh air intake, the rigid duct length will be approximately 9ft but will have 3 elbows and 2...
I do have an HVAC engineer who mostly does commercial work but trust me in the NYC area, it takes a lot of effort to keep these contractors honest. I've spent over **** in failed HVAC installs over...
Some design issues - obviously my primary goal is to move the dehumidifier as close as possible to both the HVAC supply trunk and the exterior wall
1) I would have to do 3 elbows to go out the wall...
Thanks for the diagram - it helps. Should I make do with just the Santa Fe 9 x 11 x 1 MERV 13 and install a filter box later on if needed or just do both at this point? I'm just concerned about...
Looking at the diagram again on recommended hvac system installation, I'm afraid the dehumidifier will pull in air from path of least resistance while I want to maximize amount of fresh air possible...
Can you clarify this statement? I only see a single kind of filter on their website listed here. Are you sure I can use both a MERV13 & MERV14?...
