Question about Heating & Cooling

1 Answer

Heating/air conditioning ducts make to much noise.

Since installation(8yrs ago) our Goodman system make a lot of air flow noise. The installer said it was due to the metal duct work that was installed. I'm tired or turning up the tv and being awakened by the air flow noise and want it corrected. How can this be done?

    So the installer is correct saying that the "rain noise" every time the units comes on is the metal duct work..no insulation inside the metal duct work, is there an easy solution other than replacing all duct work??

Depends if your main trunk line and your return duct are insulated on the inside or outside,if it is not on the inside then that would sound like a heavy rain every time it comes on.

SOURCE: manual air duct damper installation

Go down to where the ducts come out of the furnace. Identify the line you want to install damper. Open duct and drill two holes directly across from each other. Take your damper and undo the nut and washer on the one end and install in the holes you just drilled. Reattach the washer and nut and now re connect the duct seal it with duct tape and you will be good to go.

If you have 6 inch ducts get a 6 inch damper. But be sure to do everything at the beginning on the duct as to divert air to other ducts.

I have to tell you that changing your air flow could develop problems if you do very many ducts. So be very aware of what you doing. All systems are put in with air flow in mind.

Goodman heating system


It really depends on the type of system you have. You will either have a furnace, high efficiency furnace, heat pump system, heat pump with gas or electric back up heat. All these systems operate differently and the problem that you are having could be caused by multiple issues, depending on which system it is. More info will be greatly appreciated. Make sure to check all filters and air flow first before going any further. The system could be over heating and tripping a limit, causing the system to stop producing heat until the unit has cooled back down.

How can I make the ac quieter inside the house?


If you have hard ducts, you can use some flex duct between the supply plenum and the hard ducts as a way to quiet the noise down.

Gas Furnace Model GMH 95070, installed May 09. Air flow from registers noisy. Installer reduced it one level -still noisy. Said it cound not be cut lower because it would get to hot due to slow air flow. I...


Seems to me, the problem is not with gas, it's with the size of the duct work. 4" diameter is way to small if the entire duct work system is only 4". The trunk line may have not been sized proper,y. so the volume of heat has now been translated into high pressure, which is why the registers are noisy.
Also 6" ducts coming off a larger trunk line to each register is the norm for 1000 sq ft home.
Also, are your registers in the floor or the ceiling? Ceiling registers historically are a little noisier than floor registers. Mainly because, they're overhead and closer to your ears. But, if they were up-sized to 6", the noise would decrease quite a bit.

Hope this helps.

Hi,
Many have sepaarate speeds for heating and cooling....check it out there should be a heat relay and a cool relay and the motor taps are hooked to each so maybe you can just do a bit of switching wires.....

But, really you probably will have plenty of air flow for the cooling side also if your running that low of a differential on the heating side...
Try it out the worst that can happen is that you will freeze up on the cooling and then you can just switch it back...

Heat does not come out passenger side of the car but comes out drivers side


There is a blend door problem.

prev.gif next.gif HEATING AND AIR CONDITIONING Refer to Section 1 for discharging and charging of the air conditioning system. The heating system provides heating, ventilation and defrosting for the windshield and side windows. The heater core is a heat exchanger supplied with coolant from the engine cooling system. Temperature is controlled by the temperature valve which moves an air door that directs air flow through the heater core for more heat or bypasses the heater core for less heat. Vacuum actuators control the mode doors which direct air flow to the outlet ducts. The mode selector on the control panel directs engine vacuum to the actuators. The position of the mode doors determines whether air flows from the floor, panel, defrost or panel and defrost ducts (bi-level mode).

Intake vent needed?


The blower motor is only going to pull a certain amount of CFM for circulation air. There is some restriction of air flow that is created when the return air system is ducted causing the air flow to "slow down" a bit. The air going into the furnace firebox is probably moving at a faster rate than if the return air was ducted. It will work and you will get the same amount of heat (energy) released but the faster moving air will make it feel cooler. Also the unit might be undersized(BTU output) for the size of the cabin and amount of airflow the blower is creating. Adding a extra filter(double) might slow down the air flow a bit to create more warmth(feel) coming from the registers. Also if the furnace and air intake is pulling air from outside(garage,closet, or under house) then the colder air from outside going into the system will decrease the heat from the furnace. It is better to have a closed system (return air inside cabin). You might want to try adding a extra filter to slow the air flow down some or use some sheetmetal and square it from the intake to try and concentrate the incoming air a little better and see if that improves the warmth coming from the furnace.

Heater keeps going off on its on also fan not


Please provide more info. When it goes off does it come back on by itself or do you have to flip a breaker? Is the furnace gas or electric? If it is not moving enough air across your heat exchanger in a gas furnace or across electric heating elements this will trip a safety switch that will stop heating but not fan. Low air speed is most likely from inexperienced or improper duct design/ installation. Duct sizing is very important to move enough air. Don't believe me try breathing thru a straw. If your unit is a gas furnace it has a flashing code that will tell you what is wrong codes listed inside unit door. Could be lots of things. Reply with more info.

Needs to register equipment for extended parts warranty for a goodman air conditioning & heating


there should have been paper work with the homeowners kit. If not goodman will mail the warranty info but you will need the installation invoice or receipt. The agreement is with goodman and the homeowner directly.

Air in my condo in not evenly disributed


I would look at having the ducts checked. Alot of them are "Flex" ducts and they collapse over time. Look for poor installation too. Sagging, hard bends and such. There could be the possibility that a duct may have come loose and some or none of the air is making it to the desired space.
I would also look at installing damper doors in the ducts. This allows for you to restrict air flow to one area which would help force are to the desired area.
I have heard of people installing in-line booster fans but I've never heard of anyone saying they work. Don't reccommend that.
Speeding up the fan will change the temp of the air to the space. Don't reccommend that either unless it has been installed at the wrong speed from day one. Outside shot but worth checking.

Good Luck and let me know how it works out.
