Find the name of the manufacturer, model, and serial number of your unit. I recommend contacting a local HVAC company with this information. They will be able to contact the manufacturer to find out the efficiency. You can even call the manufacturer directly and they may be able to get you the information you seek.
Many variables including size, efficiency, brand, and so on. As a general answer 3-10000 usaully 3 for a smaller system and 10 for a large high efficiency unit with options.
HVAC unit is basically combination of HVAC chiller and all related equipment. See below related link for all details
There is NO typical home central hvac unit. Like fingerprints, all units are created differently. The efficiency (or SEER) varies greatly and the TONS of cooling do to. Between those two intangibles you can vary from about 2 to 8 Lbs. of "freon". There is NO typical home central hvac unit. Like fingerprints, all units are created differently. The efficiency (or SEER) varies greatly and the TONS of cooling do too. This creates two intangibles that cause the refrigerant level to differ quite a bit. Smallish units with a high efficiency rating can be as low as 2 lbs. A large 5 TON system can take as much as 8 lbs. Hire and trust a good HVAC mechanic.

Finned Tubes enhance heat transfer efficiency, reducing energy consumption in HVAC systems.
Cost of a furnace depends on the efficiency, the brand unit, transitions needed to be made, and the cost of a quality installation. I recommend getting estimates from qualified and reputable HVAC companies.
Because the drain is clogged.
Plug your unit into it and play it loud
