All-in-one Heat and Air System (HVAC) What's it called?

Question

We need to replace our HVAC system. It is an all-in-one unit (with Heat and AC together) that is all outside . We know there is a specific name for it but can't remember what it's called.

Answer 1

If it uses gas for the heat it's commonly referred to as a gas pack. The pack is short for package as in heat and AC package.

There is also a non-gas one which would make it a heat pump.

The information you have provided is really too vague and incomplete to answer accurately. Properly sizing a heating and cooling system should not be done by using a BTU per square ft method. I realize that this is a common method used by contractors but it usually results in a system that is over-sized. This costs you more money in installation and also operating costs because they cycle on and off too much. Think off a Ferrari in a traffic jamb. An over-sized air conditioning system will be inefficient and may actually make you feel less comfortable than if you hadn't cooled the room. When an AC is too big, the air is cooled rapidly and it shuts off. A small amount of air passed over the cooling coil, therefor only a small amount of moisture was removed from the air. Since the temperature went down more than the absolute humidity, the relative humidity actually went up! The air in the room will now feel cold and clammy and the sweat is still not evaporating from your body. This is why proper sizing of an HVAC system is so important. The size of a system should be determined by a heat loss and heat gain calculation. This can not be accomplished by anyone on this website without detailed plans of your house. What I can answer is the last part of your question. I would not put window a/c units in the house. You already have the necessary duct work in place. Window units will be far less efficient making them costly to operate. They are loud. We call them window shakers for a reason. They also don't distribute the air well throughout the building. They block your view out the window as well as render the window useless for those nice days when you want to open it for some fresh air. So given that long winded response, the best advice I can give you is to replace the unit with exactly what was there before. Of course that is only if you were comfortable before. Do you know what was there before? Maybe a service guy has a record of that.

Answer 4

Dual Pack Hvac

Answer 5

If you're referring to an HVAC central air system with an indoor unit and outdoor unit, the outdoor unit would be referrered as a 'Heat Pump'. This functions the sameway a normal airconditioning unit does in the summer to cool your house / area, and operates in a 'reverse' manner, so to speak, in the winter time to heat your house !

If you upgrade to newer equipment, check to see if the contractor is changing from R-22 to R-410a (the type of refrigerant). Insist that the 'lineset' (the pair of copper tubing) be physically replaced with a new lineset.

Answer 6

Heat Pump

Answer 7

How about HVAC combo system? Heating, Ventilation, Air Conditioning....with air purification, or humidifier etc. See link below. In California many folks use a company called Trane.
