    A couple of years ago, my AC went out and we hired a local guy to install a new unit for us. We had a 1600 sq. ft. loft with skylights and an open floorplan. We were using a 3.5 Ton unit, but he suggested that we upgrade to the 5 Ton unit. Which we did. It has been really loud ever since and...

    Hi, Can I replace a junction box with a short series of reducers and wyes? We had our HVAC installed a few years ago before ripping out our obsolete oil boiler system. We're now updating our basement - the new HVAC was sized/vented for an eventually complete basement but, at the time, the...

    Does anyone have any experience painting or covering flex duct work? We would like to avoid replacing the duct work to galvanized but would like the existing duct work to be black in order to blend with the exposed ceiling. There will be an overhang over a bar that will allow the duct work to...

    As my contractors finish installing ductwork and the air handler for my central AC system, I would like to have a measure of how many CFMs come out of each register, as a function of how the system is designed. IOW, if there is significant disparity among solidly quantifiable measures (coming...

    Hello. I am new to this site. We are in the design phase of a kitchen remodel. There is a HVAC duct in the wall that is shared by our kitchen and dining room. It does not serve the kitchen or dining room (both on main floor), but is a duct that has been run through the wall to serve a...

    Hi all - I searched your forum and didn't find a similar question/answer so I'm posting. My apologies if this is a duplicate, just point me in the right direction. I live in an old (1920) city duplex with very shallow closets. We're considering builidng out the guest room closet as a DIY...

    I live in a house that was built 5 years ago. One year ago this winter we began to notice strong exhaust fumes in our utility room and the CO monitor in the basement frequently began alarming. We called the sub contractor who had installed the water heater flues. For $100 he did the following...

    I live in Toronto. The house is was built in 1902. Major renovations to the electrical, heating and plumbing were done in 1995. I am going to build a walk out entrance for the basement. As a result, I will be underpinning the floor to increase ceiling height. In order to maximize the living...

    Hello All- Thanks for having me aboard. I'm reasonably handy around the house but admit ducts and ductwork are not in my skillset. I've found a house that I'd like to bid on, a large ranch with rehabbed first floor and raw basement. Finishing out the basement would result in a very...

    Hi, I'm a homeowner that likes to crunch numbers. As part of a larger renovation I'm evaluating the existing ducts to determine what, if anything, should be changed. I got ahold of Manual J and used it to calculate heat loss and infiltration for all the rooms in my house. But now I'd like to...

    Hello everyone. Long time lurker, first time poster :) I have a grill on my cold air return duct right at the intake to the furnace, just before the filter. This intake is allowing basement humidity and odor (cat boxes, etc) to permeate the entire house. Can I seal this off without any...

    Hi there, I know that this is an odd thought. I have an unusual house, it was an old mechanics garage built in 1934 and now we live in it. You can see it here: http://1923mills.blogspot.com if you are interested. Anyway, much of the house requires exposed ducting for A.C. (heat is in-slab...

    Hi folks, I'm planning to upgrade my forced-air HVAC system in mid to end of summer with a full Heating and A/C system. The current system is an old oil fired Magic Chef unit with no AC on a basement tank. The current heating company (at time of purchase) came out and performed some...

    I have a ranch with full basement - about 2400 square feet total - 1200 on main floor and 1200 in basement. I have a forced hot air system with adequate heat and return vents on main floor, but only heat vents in basement - no return vents. I use a free standing pellet stove in the basement...

    In my home I have 3 floor registers that are not hooked up to my HVAC system. Will it hurt my system to split the existing duct lines to make the other unused registers work?

    My husband is certain that he can install a furnace and all the needed ductwork in our house. I am not so certain. I need to know what exactly needs to be done so I can talk through this thoroughly with him. I do not want to go without a furnace again this winter. Our house has no existing...

    I am doing some structural work in my basement and the only way to get in the steel is to take down a span of ductwork, or to cut it. It looks like I can take out the piece I need to, it's about 3 feet long, on one end is an elbow that turns it upstairs through the floor, and the other end it...
