it looks like some #'s from 7th edition MJ. Big problem I see is with IECC i need to be able to apply the U-values and SHGC and this form has default for double pane. Not all windows are the same...

If you are not going to use the right draw from Wrightsoft then an alternate would be elite and is simple to use. Not sure about johnwrite software, but I would use the ACCA approved software. Both...

do not install anything without a manual J first. Your window upgrade will more than likely change the required Btuhs to keep your home heated and cooled.

Honeywell Thermostats with Redlink are Honeywell's wireless line and there are a few programmable thermostats to choose from.

I have installed a few of those and they are nice units. If I remember correctly the MERV filter is closest to the furnace and the doors have changed in the last 2-3 years, but I could swear there...

all contractors should run a Manual J to properly to identify what system size you should start with. From there I would decide two systems vs. one with zoning. Something else to think about when...

May need more information to better understand the problem. You said it is a remodel and I see stairs going down, maybe it is a chase required for something that is existing. My thoughts are either...

:) nicely said, George

HC16 is somewhat less than the Pureaire. The HC is a MERV 16 media filter which is one of the better media filters on the market. Most of the Honeywell filters you may see at home depot are MERV...

You can install an exhaust vent on a wall in lieu of the ceiling, but look at the manufacturers specs. Some require the fan to be so many feet above the ground. Also keep in mind the depth of the...

Great questions.

1) Should I get an load calculation for each quote? I am a bit concerned about going with a 110K when the existing 100K 90% unit has worked well and I have made some...

you will need to verify with residential & energy codes for your climate region. Most are minimum of R6 within the building envelope. I am in the southern region, R4 maybe suitable for up north

the 4" media filter at the air handler is the way to go. What size is your unit? Sizing is important to determine which filter to use. Common sizes are the 16x25 and 20x25. On the 4 and 5-tons...

there may be different warranties. The comfort series may also be slightly quieter and the cabinet is slightly different.

No difference between Carrier and Payne they are the same company.

That's a Carrier heat pump... if you install it I would make sure to replace the evaporator coil as well so that you have a matched system that can deliever the capacity and SEER expected from that...

Not a fan of UV lights either, they actually cause me more headaches than they are worth.

I highly recommend 4" media filters. My choice is the Honeywell F100. I would use a MERV10 filter for...

Pics are helpful. The work looks clean and from your pic I see the moisture around all the connections and not the actualy unit itself. This tells me and is visible on your pics that your system is...

In my neck of the wood lot of contractors use duct board triangles in lieu of sheetmetal wyes.

Manual J is a must, but a three ton two-speed w/ variable speed AHU may be fine. We do not know enough about your house construction to base tonnage on square footage. I do know that your two speed...

& minimum duct on each should not be less than 16"

the new honeywell redlink system is awsome and is affordable. You dont have to run the wires and if go with the optional portable controller you can enhance your temperature control and comfort. ...

the outer liner is like a vapor barrier, but also holds the duct together when you make your cuts to fold duct. If you flip it over you will cut the foil causing the duct to fall apart.

Are you...

If I'm not mistaken that is an older unit. I believe that the old horizontal coil would have been a CK3BXA030 or CK5 for an upflow. The new coils are CNRHP3017 or CNRVP3017. The "R" is for R22 if...
