Question about Master Bilt MBP-E1LZ0120B Low Temperture Evaporator Coil 12 000 BTU Air Conditioner

Open Question

Why would upflow trane furnace model # TUD1B080A9361AB installed with new outdoor unit in July 2012 Air not cooling ?

Air conditioning not cooling, fan blows very light (weak), concerned about incorrect installation pump and filter outside furnace, also air filters and filter rack not installed all air filters on side of furnace cabinet covered with white foam putty, difficult to remove and change filter monthly. Told top of furnace was connected to flow outside but where? Not connected to our chimney. How can I find out if improper installation it looks messy with all that white putty covering half of the new furnace. Our old furnace lasted 30 years. HAVAC repair man claims new evaporator coil is leaking because there was dome grease on his finger when he touched behind it. Oh yeah the evaporator coil is the only part inside the furnace. Shouldn't all parts be inside? I all vents are blocked how does the air circulate?

SOURCE: can you connect two evaporators to one unit

Yes you can each freezer would be independent of each other by the metering device used on each coil.

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,

Brand New 2 weeks old 4 ton Trane compressor leaks a lot of water onto pad


If the unit is running in cold weather than there is ice building up on the coils located outside. This is normal in that the unit is running in heat pump mode heating inside and cooling outside, After the unit detects the ice build up it briefly reverses the cycle heating the outside coils melting(defrosting) the ice which you observe as water on the pad.

The video gives you an example of the defrost cycle!

Where is the fuse in a 1984 Trane indoor unit?


in an upflow furnace you take the upper door panel off-there is a rectangular metal box with small wires to it-you should see a round plastic knob looking twist left or right then pull and you will find the fuse

New A/C Unit makes loud noise when it starts up


It shouldn't be too loud. You don't explain where the noise is coming from? The air handler/furnace or the outdoor unit.

AC is not cooling


Problem #1:Outdoor condensing fan motor has stopped running. This problem could be caused by a bad motor run capacitor. If your motor capacitor is not the problem, then more than likely you need a new motor. Is the fan blade tight, stiff or hard to turn? If the fan blade is hard to turn then you probably need a new motor. Problem #2: Air conditioner compressor will not start. When power is applied to the air conditioning outdoor unit the fan starts, but you hear a sound like the compressor is trying to start, "UGGG"..., for about 5 to 10 seconds and then all you hear is the outdoor condenser fan run. The compressor is locked and will not start. What is happening is the compressor is trying to start, but because the compressor motor is locked it tries to start for a few seconds and then because of the high amperage being drawn goes off on internal overload. The internal overload protects the compressor windings from overheating and burning up. I see this many times during the start of the air conditioning season. Some compressors just have a hard time starting after sitting all winter long. Some compressors are locked up so bad that I can not start them and must tell my customer that they need a new compressor . Many times I can get the compressor started again without having to buy a new compressor or new air conditioning system by using the device that is called, "Super-Boost." I keep two or three of these on the truck. They have saved many of my customers from having to buy new air conditioning systems.

Due to the many different questions I see about Air Conditioning, I am including this overview to help us better understand each other for trouble shooting. A basic air conditioning system has a Thermostat, Air Handler or Furnace Fan and a Condensing unit. In a split system, the condensing unit (Condenser) is separate from the furnace and usually in the back yard. When working properly, it blows hot air. It connects to the cooling part of the system by 2 copper lines. One large line and 1 small line. The part that cools the house is the "Evaporator" and is usually on top of the furnace inside the square metal box (Plenum). When the Air Conditioner is running, the large copper line should be cold and the smaller line should be warm. Common signs of low refrigerant are that both lines are the same temperature and/or frost or ice has built up on the large line at the condenser. The thermostat will normally display room temperature on till it is touched to change the setting. It could have a "Span" setting as well as times and temperatures. The operating "span" of MOST residential thermostats is 40 to 90 degrees. That means you can set it as low as 40 degrees and no higher than 90 degrees. It probably has a fan switch also. When in the "ON" position, the fan will run constantly, 24 / 7, but the condenser will still cycle on and off as needed to keep the house at set point. If you have a suggestion to include in this paragraph, please let me know.

I think I have it covered above. Let me know if you need something more specific. Thank you. Roger
