My central heating and air-conditioning unit completely stopped working - the model# is e2eb-015hb

If your system starts to blow cool air when your Nest thermostat is in Heat mode (or if it blows warm air when its in Cool mode), change the settings for orientation of your heat pump. The instructions depend on which thermostat you have

How a Central Air Conditioning System Works



Facts:

• The typical central air conditioning system is a split system, with an outdoor air conditioning, or "compressor bearing unit" and an indoor coil, which is usually installed on top of the furnace in the home.
• Using electricity as its power source, the compressor pumps refrigerant through the system to gather heat and moisture from indoors and remove it from the home.
• Heat and moisture are removed from the home when warm air from inside the home is blown over the cooled indoor coil. The heat in the air transfers to the coil, thereby "cooling" the air.
• The heat that has transferred to the coil is then "pumped" to the exterior of the home, while the cooled air is pumped back inside, helping to maintain a comfortable indoor temperature.
• Central air conditioning can also be provided through a package unit or a heat pump.

Benefits:

• Indoor comfort during warm weather - Central air conditioning helps keep your home cool and reduces humidity levels.
• Cleaner air - As your central air conditioning system draws air out of various rooms in the house through return air ducts, the air is pulled through an air filter, which removes airborne particles such as dust and lint. Sophisticated filters may remove microscopic pollutants, as well. The filtered air is then routed to air supply ductwork that carries it back to rooms.
• Quieter operation - Because the compressor bearing unit is located outside the home, the indoor noise level from its operation is much lower than that of a free-standing air conditioning unit.

Put new batteries in the thermostat. Make sure that the switch that power the furnace is in the "on" position. Sometimes people mistake that switch for a light switch and turn it off.

it may have frozen and loosened someting it might just need to be seviced

any sequencer will work as long as you have the same number of stages. hope this helps.

Hello, sounds like it is either a low charge or lack of airflow, what type of filter are you using? sometimes those filters that claim to be super effecient will actually cut down on your airflow and cause the ac to freeze up.

There is a drip pan bit the middle is open to allow air flow through the coil and into your ducting. If the drain for the drip pan is clogged it will fill up and overflow onto your furnace and then to the floor.If that is what is happening then clean out the drain tube running down the front of the furnace and it should empty the drip pan and solve your problem.

You also need to have your furnace checked for water damage in the electrical components, if these have gotten wet then you run the risk of a fire. Please consider calling an expert in your area to inspect your furnace and make sure the drain line is clear.

Are you getting 120 vac or 220 vac at the unit? Check the voltage at the first terminals inside the unit as well as the breaker. You should have 220 vac at the elements and you are dropping a leg some where.
