It would depend on the MERV rating of the filter, a "cheap" Blue Non Pleated Filter would have like a MERV 4 or 5 rating, and your pleated Could be MERV 8 and you would have a very normal pressure...

Oh wait, I did look at his spreadsheet wrong, But I also noticed on the spreadsheet, the Heatstrips are used 22%...So, if you still go with my theory, and use the baseboard as primary, HP secondary...
Well think about it this way, He has Oil fired boiler that serves his Perimeter Baseboard Heaters, and the oil is cheaper than the electricity ( unless I looked at his spreadsheet wrong) the base...
Depends on the style of filter you use, but you definitely need to filter the outside air. (dust, Pollen etc) I use a double filter set up, I have a pre-filter that is just the cheap disposable style...
Are you just concerned about the Return air or also the supply air? If just the return, you may want to consider having a return Duct put in, maybe a chase can be built in some closets and flex duct...
Have you considered making the Baseboard Primary and the HP aux heat? Just to try it out.

One alternative you might consider is IN-Floor heating system for a space that small, has a low electric consumption, and could appeal to some buyers. Depending of what type flooring you have in the...

the answer to your question is...yes

i have never worked all aluminum duct work , but you may want to read this

Aluminum oxidizes...heat exacerbates this condition, in the furnace...
is this metal ductwork? with the insulation on the outside? just a couple guesses, the white powder is the galvanic coating coming off inside of duct due to the oversized furnace (to much airflow/to...
well at least you have electronic leak detector, I'm just going to guess here, but i think you have restriction in your metering device, pump the unit down and check the orifice and add a proper...
yes I agree....and yes that is what he is suggesting
1. Superheat is relatively meaningless until the system is at or near its design temperature. At high loads, the superheat will tend to be high and decrease as the load drops. If you try to set SH...
with that theory then what if i had a extremely long lineset or a oversized condenser..then i would still not consider subcooling? I can understand if your checking subcooling at the outlet of the...
where did you read that? I have never seen that...and I am currently teaching advanced commercial refrigeration and no where in the book does it say anything of the sort. at design temps why would...
what is brand/make of unit? may be able to ask builder/developer to simply add iso pad supports under unit or a compressor blacket/noise reducer to help reduce some start up noise if that is the...
a small room/workshop with a window unit would work, but yes the discharge air back into the main space would add heat. i would start with exhaust fan on one end of barn and vent/window intake on the...
i would hook it up to that new pool....make it a hot tub...
there's an arrow?
it is a wide range question to answer, Delta T is dependent on many factors, ambient conditions, equipment, design, age of equipment just for starters. the tech may be able to adjust, but to charge a...
i think what there suggesting is a exhaust fan on one end with a fresh air intake on the other end, simply drawing air thru the space will have some what a of cooling effect. only option you really...
looks like very nice install....no pans under the tanks required?
sounds like you could have restriction. you need a HVAC service company you can trust to do things right. I would ask around to neighbors friends and family and see. IF you dont trust that techs...
wow, i thought 3% was high...but our union really does nothing...
ok major issues with fan in on position, move to auto for sure. the indoor coil is wet and your blowing air across and throwing moisture right back in the air when the outside unit cycles off....
no idea what size, but if you search this site there is really long thread on using oversized caps...been a long debate...
each manufacturer different...but basically they monitor 3 legs of power, if one leg drops then it will cut out control circuit, some have a adjustable delay for time out.
that would be red flag for me...I agree with herefishy42 check SH and TXV i'm guessing restriction...
I agree on adding a factory start kit and CC heater, as far as ratings go...you will have to talk to another engineer....I have questioned engineers about designs and get the same answer " you...
restriction maybe...why was the compressor changed? was there new dryers installed?
is the basement part of the conditioned space?....one solution would be to condition the basement with the access AC so you can eliminate need for Dehums...
well I know you hate to hear it , but husband is on the right track. the longer your unit runs the more RH is removed, but your digital t-stat with RH % reading should force the unit to run longer....
you come across any 9mm or .45 LC rounds laying around let me know...lol
love Dubai, looks like a good course. prices are not bad.
don't forget , that furnace may not be able to be installed horizontally any way, so you would have added cost of new furnace

Fujitsu Mini splits are superior when it comes to noise and vibration, even if a fan blade broke ( seen in many mini splits but not Fujitsu) the vibration would probably not be noticeable less your...
if you can locate the damper look at it and listen to it...have someone activate the t-stat and see if there is any noise or sound change. do not dismantle it as there is voltage inside of it. on...
