The thing here is the fact that EVERY single HVAC tech that comes out to my house only wants to service my outside unit (gas pack ) they do NOT care about my ductwork, don’t wan’t to see my ductwork and will not give me a straight answer on anything to do with ductwork .It’s like it doesn’t even exist at all !

I hear you. Even the company I bought my new $5, 000 HVAC system gave me some bad information. I was not getting enough air flow upstairs so I asked if they sized my A/C correctly. He said they did. I then said I heard that dampers can be adjusted to move air better. He told me the dampers were set in the optimal positions and that wasn't the issue.. Turns out he was either incompetent or just didn't want to deal with it.

I looked it up on YouTube and then played with the dampers and sure enough, one was only open 50% and when I opened it 100%, the air flow is now stronger upstairs. So much wasted time dealing with it being 68 in the basement and 78 upstairs when all he had to do was adjust them 2 years ago.

Shame on me for thinking a professional HVAC guy knew what he was talking about or was giving me the best advice. Just like any other profession, some are just phoning it in, while others go above and beyond.

I have a couple of rooms that are hotter than the rest of the house, and our house is a singe story house.

Most common situation: Hot room in upstairs and HVAC in basement/first floor. Added air return to upstairs is ~35ft long while basement air return is ~3ft long, so the intake pull from upstairs is low. In addition to solutions noted (manual damper, adjust registers, add fan to register), why not add fan to air return as well to help pull the hot air from the upstairs return?

[cyclonelaundry]

We added an additional return in our hot room as that helped pull out the heat from the room and added additional circulation. We had to do a calculation to see if this was possible 1st.

Thank you. As a home inspector I see this issue several times a week and it usually leaves my clients bewildered. I’m baking a link to this video into my reports.

Reduce duct truck right and balancing needed, no your cfm math

My "hot room" is located above the garage and experiences significantly higher temperatures compared to the rest of my single-story home (76° versus 82° to 83°). Despite trying various attic-based solutions to alleviate the heat, they have only marginally improved conditions by about 1 degree. Compounding the issue, the room's air conditioning return is inconveniently located at floor level, exacerbating the heat buildup. The furnace directly beneath the room provides a short path for air circulation.

Given these challenges, I'm considering two potential solutions:

1. Installing an additional air conditioning return duct in the ceiling of the bonus room, positioned centrally for optimal airflow. Although this may involve complex ductwork through the attic, it could significantly improve air circulation. I currently use a ceiling fan, but I'm willing to turn it off if it enhances the effectiveness of the air conditioning.

2. Exploring the option of installing a quiet ceiling vent fan designed to draw hot air from the room and exhaust it into the attic. While this approach may result in some air conditioning loss to the attic, it seems like a viable option given the current circumstances.

I'm seeking advice on which of these approaches would be most effective in addressing the overheating issue in my bonus room.

I put a 6" inline fan half way down the duct to the room and installed a sail ( Pressure activated ) switch in the main run line. When the system turned on, the line boost fan came on. Although it worked, I had to remove it because it was quite noisy in the floor area of the room. Those type of fans are made to exhaust air from greenhouses, so the steep angle on the blades makes for a lot of loud air movement.

In the summer the basement is colder than the rest of the house.

[johnsonjay]

Fix duct, booster fan (inline grow fans are cheaper) been using those here and there blowing peoples minds 😉 zone system, balance duct.

My house has the duct under the house can you make a video towards this type of homes

[catsmeow]

Are the "dampers" the little flaps inside the duct? My house has round vents with pull chains (like the kind you see on ceiling fans) and metal flaps inside. The hottest room in the house has a flap that is stuck and doesn't seem to want to open all of the way. 2nd hottest room has the same thing but the chain is gone and I don't know how to get it to open back up or how to get it to stay opened properly. I'm sorely tempted to get on a ladder and try to tear the flap out entirely.
My house doesn't have floor registers. It's a single story house and I don't know how floor registers would even connect to our central AC.

I’ve seen in my ranch home. I have three bedrooms and a bathroom next to my thermostat in the hallway. If I close the bedroom and bathroom doors, the air conditioner runs longer. Should I leave my doors open or shut which would be better to cool and heet the house and dehumidify better with a dehumidifier in the basement, just curious

Hello I see you are in 804 Area code. I have a Question , I had a Modular home built and The Builder used All Half Assed Subs. Our HAVC guy did a Half Assed job !

I have the Fkex Duct work that's 80% closed off by Just Hanging in a Single Strap in Long Distances.
I am going Replace the Duct work myself. I believe I have enough To figure it out and I do have the Sheet that was Supplied to County for Approvel, I will have to put in Valves - Dampers so the Air Will not Over Power each Room . Basement is Open .
But my Question is
Our Garage does not have And Heat or A/C in it, Could I Run 1 Metal Duct work in Garage , garage is a 24'x30'
Whole house is Super insulted, even the Garage has 6" outside walls and Great Insulted Doors on it.
Does the Garage Have to have a Return,
Seeing it is a Garage not Living space - I say Not

When I do the Duct work in basement I will put in the Dampers and Cover the Duct work so it is Insulted Good and will use the Super Sticky Tape for the Ducts when I do them . I am going to Run a Pipe Metal Duct into Garage and Put a Damper on it to regulate the air so it does not Over Power that Garage, and Make Sure it Has Alot of Bug Screen over it . Even though we have No spiders in house because we have a good exterminator here in Area that come 4x's a Year
The Duct in Garage will be on House side of the wall and I will enclose it and insulate it when I pit it in using Boards and Drywall it

Whats your thought.
I Ended up Firing the Builder and Finished the House myself !!


I don't have any $ left to pay to have someone do the work. I had to Hire people to Fix Builders Subs Work, Shingles put on back Roof Sideways , Vent Pipes on Roof Flashing On wrong, the Ridge Vent on Roof looked like a Snake Crawing across the Top. Where the Chimney siding was Not Finished, Eve Flashing was 1/2 on house. Builder Kept having Subs Coming Back, and Back.
No wonder Subs Kinda did not Care !!!
Builder I belive He did not Know How to Use his Subs and Had then Do Piece work here and there. Never Finishing There Job.

Siding guys shoukd not have even come till house is ready to wrap !!!
Even the County Inspector's Did not Catch the Uber Ground Rod Was Not hooked up to Ground of outside Grounding.
Breaker's in breaker Box Was Rusted. I hired a company come in Hook up my Standbye Generator and rewire the panel Box !!!
Yep Even the sub Electrian was Horrible . I told Builder to Fire him from the Get Go !!!
The Electrian was Also the Plumber !!! Tell me it's not crazy

[dandyd]

Approximately how much does it cost to clean out the ducts in general sir?

[chrismichelson]

How about inline fan in the duct from main box to 10 inch hose to master bedroom bath closet. My duct hoses has been replaced all new hose.

[wellbeing]

Does adding a return air pattern vent above the door coupled with the vent fan potentially increase cooling of the room? In the desert the SW room seems to be quite hot from the afternoon through setting sun and in a small room where they diverted the HVAC and it’s too small for the room, plus external sun on walls and a wall butted up to a hot garage, it’s pretty brutal. No regular fan does anything and other parts of the house are too cold if you run the a/c just to accommodate that room. I’m trying to find a solution to help, not necessarily correct it, since that probably involves something quite extensive. I was thinking of trying the RAP above the door, but that vent fan would probably help alongside the RAP. If the HVAC vent wasn’t in front of the sunny window, I feel it would help because it seems the hot side of the room just warms that cool air so it can’t move through the room while still cool so any room fan just blows warm air.

[toddytwotones]

Only one cold air return vent on one side of house. Adding returns to bedrooms on other side help?

[teresacorley]

Are house in most rooms get so cold that if I turn off the air it's better and the temp throughout the house is so off the bathrooms are usually freezing to where you almost want to plug in a heater until your done showering
