We have just moved in to our rental house which has been empty for a while, it has a Vulcan cx heating/air conditioning system (reverse cycle I believe), we have tried unsucessfully to get the heating side working, all we can get is cold air blasting out of the vents.
We did ask someone to have a look, he said the pilot light had gone out and he re-lit it, the unit kicked into life and you could see the gas meter moving so gas was getting into the system, I left it running for a while but cannot get any hot air coming through. We have no instruction manual to work with and we are finding it rather cold, can you suggest anything we can do.
If your meter shows gas is flowing but you are getting no heat you may have a potentially serious problem. Since you are a renter, call your landlord or leasing agent today and tell him the situation. He should send a qualified technician to check your system.

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.
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.
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.
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.
Indoor comfort during warm weather - Central air conditioning helps keep your home cool and reduces humidity levels.
- 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
- 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.
Air Conditioning is easier to add to an existing central hot air heating system then you might think. Both systems use air to move the heating or cooling to the different parts of the house. With the addition of a coil and condenser to your system you can stay nice and cool all summer long.
The easiest way to add in cooling to a system is to install a coil on top of the furnace supply air plenum. This can be accomplished by cutting open the supply duct just on top of the furnace and sliding the air conditioning coil right in on the top of the furnace. The only limitation usually is the height of the plenum. If there is not enough height there, then the coil may need to be installed on a horizontal run.
If the horizontal run option is needed then you will have to make sure that all of the air flow goes through the run. If all of the air does not go through that run, then the ones that do not go through will not cool nearly as effectively as the rest of the runs that go through the coil.
After placing the coil in the ductwork, the piping and electric will need to be run to the outdoor condenser unit. After wiring and piping the unit the refrigeration lines will need to be purged, and vacuumed. This will clean the lines and take the air out of them. Any air in the system will cause the system not to work properly.
When all of this work is done you will be ready to have great cooling. The whole process usually takes me less than a day to complete. Adding cooling to an existing system is a simple operation when it is done by someone that has done it many times. If you have a hot air central heating system without the benefit of cooling, then you should check into adding the cooling feature to your system. You will be glad you did when the hot weather rolls back around again.
sounds like you need a new thermocouple. Its the sensor that sits in the pilot flame and has a copper tube going back to the gas valve. All you need to know to get one is its length. They are cheap and usually found in hardware stores, It sends a signal to the gas valve, telling it that there is a flame once it gets hot.
This unit is a cooling unit only. I don't know what switch you are looking at but I don't think it's for the evap. cooler(swamp cooler). I am in the Phoenix, Arizona area and it's very common to have a evap. cooler and a seperate heat/cool system as on the hottest days the evap. cooler doesn't cool enough. I hope this helps. Please give me a positive rating. Thank you.
The control panel gets its power from the central heating unit's power point. Try turning the power off outside at the powerpoint next to the ducted heating unit and try turning it on again after a few seconds, see if it resets
