Where is the duct work located? In an attic, crawlspace? It sounds as if part of the system is disconnected. Are the outlets at the floor or in the ceiling? Is the duct work insulated? Can you take actual air temperatures at the outlets?

SOURCE: unbalanced cooling or heating

You need to balance the system. It's a matter of adjusting the dampers or registers so that you have a little less air flow near the T-stat and more to the other end of the house. Likely you have a return vent near the T-stat. That return draws air to it and likewise the T-stat. If you are getting a lot of air out of the registers on that end of the house damper them to force more air to the other end of the house. Do not close them entirely though. You may have to play with it a little to get it right. I hope this helps. Please remember to rate Fixya rate me.

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.
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,

Our vaulted living room ceiling has black smudges coming through the paint...we have used Kilz paint and repainted several times...also had vents put in the roof

Did you happen to spray the mold with Bleach before covering up ? If mold is still in growth mode even Kilz cannot keep it from penetrating.. Usually half water and half bleach would be ok. Just vent the house well.

No heat through vents

Does your condo have more than one thermostat? if so there are powered dampers that open and close to direct heat where it's being called for. You may have dampers stuck/inoperative.

Friedrich RS10J10-C: Only half the coils are chilled...

If the evaporator coil is only half coated with water, this means it is low on Freon. You need a repairman to fix the leak and add Freon, but this costs way over a hundred dollars.
