Can a central air conditioning unit have too many btu's for maximum efficiency?

The size of the unit in btu does not affect the system efficiency. The way a unit is built and matched to an evaporator determines its' maximum efficiency. An oversized unit affects the comfort level in the home because it will not have a long enough run cycle to adequately remove humidity.

How do you tell what ton an ac unit is?
An HVAC system is rated in British Thermal Units (BTUs). For example, a 2-ton air conditioning system is 24,000 BTUs. That's 12,000 BTUs per ton. So a 3.5-ton air conditioner is a 42,000 BTUs.

How do I Convert hvac seer to tonnage?
Determine the SEER rating of the HVAC system. The SEER rating is usually provided by the manufacturer and is a measure of the system's energy efficiency. Find the total cooling capacity of the HVAC system in BTUs (British Thermal Units). This information is also typically provided by the manufacturer and can be found in the system's specifications. Plug the SEER rating and the total cooling capacity in BTUs into the formula: Tonnage = (Total Cooling Capacity in BTUs) / (SEER) For example, if you have an HVAC system with a SEER rating of 16 and a total cooling capacity of 48,000 BTUs: Tonnage = 48,000 BTUs / 16 SEER Tonnage = 3 tons
How do you convert A air conditioning unit from btus to tons?
The formula is simple. One ton of cooling equals 12000 btu. So a three ton A/C has a 36000 btu capacity.
How to Choose the Right Portable Air Conditioning to Meet Your Needs?
With the approach of summer, some people may be thinking of improving their air conditioning capacity to deal with the heat and humidity, often associated with that time of the year. One solution to this problem is using portable air conditioning to bring some cooler temperatures and much needed comfort. Mostly designed to be used in small spaces such as an office, a bedroom or the kitchen, the type of portable air conditioning unit required will depend on the location and the size of the area to be cooled as well as the type of controls you prefer. You should also base your decision on the length of time you plan to use the portable air conditioning, the noise levels and accessibility to adjust the unit from time to time. In choosing the right portable air conditioning unit to meet your needs, there are some factors, which you should take into account. •The BTUs (British Thermal Units) rating per hour, which generally range from 5,000-12,000 for portable units, define the capacity needs of the area for the air conditioning. For areas between 100 and 150 sq. ft, BTUs ranging from 5,000-7,500 are recommended and for 450 to 550 sq. ft., BTUs from 12,000-14,000 are best. The recommended BTUs may vary depending on the manufacturer. Certain conditions, including very sunny and hot areas and the number of persons in the room, may require an increase in the BTUs. •Aim for a high Energy Efficiency Ratio (EER), which is an indication that the unit costs less to operate. Good EERs range from 8-11 and you can calculate them by dividing the BTUs by the wattage. •Depending on your preferences, you should decide on features, whether you want the oscillating type or the unit with fixed louvers. •Choose the venting process, whether self-evaporating, which does not require you to empty any water tanks or the units, which have exhaust hoses and are vented out of the window or wall. •Decide on the kinds of controls that would best meet your needs, including manual or remote control, programmable timers, automatic restart after power interruptions or control settings to allow louver vents to swing automatically.
How do you assess airconditioning capacity?
Air conditioning capacity is typically measured in BTUs (British Thermal Units) It correspond to the amount of heat it is capable of removing. The higher the BTU rating, the more powerful the air conditioner.
What air conditioner has the most BTU's?
With 28,000 BTUs, the Friedrich SL28L30* has the most BTUs.
How many square feet does 4800 btus heat?
4800 BTUs will 150 square feet.
How can I determine how many BTUs I need for an air conditioner?
A small room is about 5,000 BTUs. Most people don't have a room that would require more than 10,000 BTUs.
How many horse power in tonner split type air condition?
Air conditioning systems aren't measure in horsepower - they're measured either in BTUs or in tons. To determine this, a specific model of AC system would be needed.
How many BTU s are in a goodman furnace GMT090-3B?
90,000 BTUs - the 090 is what tells you the BTUs of the unit.
How many btu per hour would be produced in a 12-kW electrical heater?
There are at least 5 different definitions for slightly different BTUs. One of them says that 1 kWh = 3412.14 BTUs. Let's use that one. 1 kWh = 3412.14 BTUs 12 kWh = 40,945.68 BTUs
