Question about Carrier Heating & Cooling

1 Answer

I am living in a home with a carrier furnace. The furnace is in the back part of the house in a store room. It has two- 2 1/2 inch plastic pipes. One that suppplies air to the furnace and the other is venting air out. Both picpes go though an outside wall. Also above the furnace in the ceiling of the room is an air supply vent bringing in outside air through an outside wall. Is there a purpose for having this second vent in the ceiling as it brings in so much cold air into the room & into the house?

As long as the fresh air intake pipe to the furnace is not plugged up the second vent is not needed some homes when they are new are air tight and need a fresh air circulation system

Does my furnace require outside air?


I'm surprised the building inspector allowed the condensing furnace you described draw combustion air from the garage !! I'm not familiar with any manufacturer that recommends that as normal practice. Virtuall ALL two pipe condensing furnaces require both pvc pipes to be terminated OUTSIDE the structure with specific heights and distances apart. There is also a limit to the length of both the flu and the combustion air piping and each 90 degree pvc elbow adds the resistance equivalant of roughly 10' of straight pipe. If re-routing is required, you have to bear in mind the direction of 'fall' in the piping usually goes back towards the furnace and remember two 45's may give you a greater variance of change in the piping and still be equal to the equivalant of one 90.

Personally, I would never suggest terminating the fresh air (combustion air) intake between floors of a structure.

Tip

Keeping your whole home cool with central air.


Sometimes it is difficult to keep your home cool in the hot summer months. Also, some areas of your home may still be hot where other areas are too cool. Try this method to keep your home cool evenly throughout. Before you get started make sure your furnace filter is new. This will allow for maximum air flow.

If your living space is a single floor plan:

  1. Turn the air conditioning on
  2. Switch the furnace fan from auto to on.
  3. Measure the temperature in each room.
  4. Close the vents by about half in the cooler rooms
  5. This will force more cool air into the warmer rooms.
  6. Keep adjusting the vents until all the rooms have the same temp.

If your living space is on more than one level:

  1. Turn on the air conditioning.
  2. Switch the furnace fan from auto to on.
  3. On the lowest level of the house close half of the vents that are the closest to the stairs.
  4. This will force more cool air to the top floor where it is usually hotter.
  5. Cool air will sink from the upper floors which will keep the area near the stairs cool.
  6. Measure the temperature in all the rooms.
  7. Keep adjusting the vents until you have a nice even temperature throughout the house.
I found that leaving the furnace fan on all the time will keep your home evenly cool and comfortable. You may have to replace your furnace filter once a month due to the increased air flow. It will be well worth it in a cooler, more comfortable, and more energy efficient home.

Take Care,

Eric

What size fresh air vent do I need in a boiler room with a gas boiler and gas hot water heater with about 220,000 btu combined


I suggest that you run a duct that is 3 inches larger than the furnace duct . and you should run it down close to the floor and aim it in the direction of the furnace. this will trap warm air above the vent and supply an adequate supply of air for combustion. also make sure you have insulated any pipes in the furnace room that carry water or steam you want heat where you live, not going up the chimney.

My high efficiency furnace has water (possibly condensation) running down the air intake pvc pipe into the furnace and all over the burner, gas valve, and wiring.


First, check the drainline from the furnace. You have a 90% gas fired furnace. Where 80% furnace has 1 heat exchanger, yours has 2 heat exchangers. And the second heat exchanger will cool the exhaust enough, that it ends up below the dew point, and your furnace outlet/exhaust will condensate. This drain is probably stopped up. Now, I've installed and service many of these systems and I've only seen the piping at the roof you described once. And that was when the roofers replaced the roof, damaged the furnace flue pipe, and tried to repair it themselves. Normally, and this may not apply to yours, we tie in the exhaust/supply lines about 2-3 ft. above the furnace. Then 1 pipe goes through the roof. Thus 1 pipe is a kit that has an inner liner & outer pipe(2 pipes in 1). Now I'm not sure if this is a problem or normal for your system, but it may be worth looking into. You should be able to find it in the installation manual, or call a local parts house that sells your brand, or as your tech. And if it's just your drain, forget all about the piping I mentioned. Hope this helps!

Make : Weil-McLain Model : CG-5-SPDN Series 12 I have the above mentioned boiler which is located on the 1st level of a three story one family house, the area where the boiler is located is insulated.


You don't have an optimum distribution of steam in your house. Try closing a little bit the valves supplying the heaters in the lower floors. Close a little bit more until you get the desired balance.

I have 2goodmanGKS9 gas furnaces(propane) installed on 27 Dec 2009. Both units are working. One is in the basement adjacent to the rear outside wall. Lower unit heats about 1200 square feet. Lower...


well lets start with the 2" pvc pipe. that is a combustion air intake it does not put air into the room, i hope. this is a 90% furnace and they should have installed it that way. there should be 2 pipes to the outside the other is combustion gases. the dust problem maybe caused by the air return pulling the air to that room. the bedroom normaly does not get the trafic that the rest of the condo does.so it would not have as much dust.

I have a Ryan's Room tent, and some of the plastic pieces that make the frame of the camping-style tent broke. How can I get a replacement part?


We had the same issue. Here's my solution.

Each tent pole is composed of 49.5 inches of half inch pvc pipe cut into three 16.5 inch pieces. This can be purchased at any hardware store. You can cut it into three pieces like the original and string an elastic line through it or just keep a piece of 49.5 inch pipe in storage to use when needed.

Goodman furnace wont come on


If this is a High Eff furnace:
1) Remove the compartment that has the igniter and burners, turn the
power back on, if the furnace lites then you have a problem with the
intake air vent, probably iced over if you live where its cold.

2)Make sure the exhaust vent is not getting backpressure from the
wind.

3) you could cut the pipes on the inside of the house to disconnect them from the furnace, test run the furnace with no pipes.If the furnace
runs then you have a problem with the installation of the vent pipes.

4) Do not run the furnace without the exhaust pipe disconnected,
go to the hardware store and get a couple of rubber clamped
couplings and hook-up the exhaust pipe!

Good Luck

Heat not coming on carrier gas pack code 31


code 31 indicates pressure switch did not close or reopened during the heat cycle....1st thing to check is the inducer motor,,this is a small motor that turns a small blower wheel that draws the exhaust gases through the furnace and blows them into the vent pipe....1st locate the inducer assembly,,most easily identified by the small plastic fan blade that cools the inducer motor as it runs..1st turn off tstat and turn off furnace power switch..then turn on furnace switch,then set tstat to heat,set the temp above room temp by 5 degrees...remove the furnace front cover,locate the inducer motor,,if it isnt turning,but is warm or hot after a minute or so,likely the inducer motor is bad..if it isnt turning and isnt warm after 1 minute,then likely the main control board is bad,,not turning the inducer motor when it should,,,,,if the inducer motor is running,,then the pressure switch isnt closing,, could be a bad pressure switch but more likely there is a problem with the venting...some possible problems that would cause the pressure switch not to close in an 80% eff furnace [metal vent pipe] are: [1] a blockage in the vent pipe,base of chimney,dead bird at the furnace where vent connects to furnace or down inside the inducer assy,accessed by removing vent pipe from furnace....if all clear the chimney could be blocked up inside,,is the draft good when vent is removed from base of chimney?..if furnace is a 90%+ type [pvc plastic vent pipe],,then check the intake pipe at the furnace by removing it where it attaches to top of furnace..is the intake clogged with anything?..then check the intake and exhaust pipes outside for blockages,,including ice/frost/snow at the exhaust pipe outlet..

Furnace-not heating all rooms to set temperature


Depending on where your living room is in comparison to your furnace it could be just that the fan doesn’t have enough force to get it there so what is happing is that all the other air is reaching other rooms before it. There are products that can help with this u can find them at larger hardware stores they r inline fans that go in the ductwork or there r a flat type of fan that mounts on the vent and plugs into a wall outlet that will pull the air to that room the latter would be much easier but it is your choice. Hope this helps.
