    Vanmeterp, What type of furnace is it? Electric, gas, oil, ???Heat pump only? To answer your question, a furnace can be installed as an updraft or downdraft or in a horizontal configuration. If the installation was properly done... then it would not be dangerous. Your statement that it is installed on its back sound like a horizontal configuration. Is your furnace working ok? Henry

The furnace can not be installed with the doors facing up. It will not work properly and yes it is dangerous. The unit needs to be flipped to its side, and the plenums and the ducts need to be changed around along with your Flue (vent) pipe, and gas line. HVAC-R Tech

Where is the air filter for a Goodman # CAPF036A2A


If this is a case coil, they do not have a filter area, the filter is normally either installed in the return air grill or needs some type of filter installed just upstream if in a down air installation in a closet. If it attached to a furnace, there is a space provided by most manufactures for a filter installed just before the air return. If the furnace is in the attic or in a crawlspace, I never install a filter in these areas, but put a return filter grill in the return path.
Hope this helps

Goodman furnace


Sounds like the furnace is tripping off on a limit safety, either temperature or air switch. Check filters and restrictions to air flow (furniture over return air grills, blocked filters) also, check the drainage line of the system. If the furnace can't drain water fast enough it will back up internally, and trip the system off on a pressure switch safety.

hope this helps.

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.

I have a Goodman forced air heating system in my attic that's only about 3 years old and I believe the pilot light went out last night in a storm. My problem is that I can't locate the pilot in the unit...


Marc, look for where the gas line enters the furnace and remove the panel adjacent to it. That should gibe you access to the pilot light. Also, look for a pilot access door, near where the gas line enters the furnace. The gas line will either be 1/2" flexible copper tubing. 1/2" black iron pine or 1/2" vinyl coated flexible stainless steel. Look for the lighting instructions inside or on the side of the unit.

Hope this helps you solve the problem.

Questionable installation of a Goodman furnace.


That seems to be the common practice. The low pressure created by the suction of the fan will draw air in from outside.

There is water leaking from the bottom of the new gas furnace. This happend last year and they said a hose was plugged. It is happening again this year and they are saying now it is because we didn't have...


No. The installers did not properly plumb you hose. You have a high efficient furnace which is really nice. However, this furnace takes out moister from the air when heating, causing condensation. I would look at the installation manual and see if they installed them properly. They might of installed the wrong unit for you home. Most Goodman furnaces can only be installed up-flow meaning in the closet or horizontal installed meaning in the attic. Look at the installation manual to see if they installed the right unit for your home. www.fastacservice.com

Goodman furnace may be producing to much water


Your furnace is more than 90% efficient and extracting so much heat from the gas that it condenses instead of blowing out steam. This is good! Figure that for every dollar you spend on fuel, you are getting back 90+ cents back in heat. Compare that to the typical units that only get 70 - 80 cents back in heat.

Yes you should drain your condensate to a proper drain via gravity or a condensation pump. I would recommend you treat the condensate first with a acid neutralizer prior to draining in municipal drains due to it's high content of sulfuric acid. You can purchase these filter type neutralizers on the net or at a good heating wholesaler.
