How do I know if my AC is 1.5 ton?
Look for an even, two-digit number between 18 and 60. Or, you might see a three-digit number starting with 0. If you find one of those numbers, chances are good it's the unit's BTUs: 018 = 18,000 BTUs = 1.5 tons.
What happens if I put a 1.5 ton AC instead of 2 ton in a room the size of about 200 sq ft?
This is not damaging to the unit because it is designed to run as needed. You just won't get the energy savings they provide by reducing the power when the temperature comes down in the room. It will just run continuously. While it will not cool a larger area well (more than 600 sq.

Why It’S A Bad Idea to Install The Wrong Size Central Air
It is important to understand exactly why it is not advisable to install the wrong size central air, whether too big or too small.
Why is variable speed air conditioner better?
And because variable-speed air conditioners control moisture more effectively, homeowners feel more comfortable at higher temperatures, so the thermostat doesn’t have to be set as low. Variable-speed models cost more initially, but they’ll lower your utility costs long-term, and they are ideal for allergy sufferers.
What is the temperature of an air conditioner?
The Seasonal Energy Efficiency Ratio indicates how efficient an air conditioner will be at a range of temperatures between 65 and 104 degrees Fahrenheit. It gives homeowners a better idea of how much energy an air conditioner will use year-round, helping them determine electricity costs.
How much does a BTU cost?
Prices range from $750–$1200.
When does a single stage air conditioner turn on?
Single-stage air conditioners turn on when the indoor temperatures exceed the setting on your thermostat. If you set the thermostat to 70 degrees, the air conditioner will run whenever the indoor temperatures reaches 71 degrees. When the temperature drops, it turns off.
Do mini splits have windows?
Ductless mini split air conditioners are similar in construction to window versions but with no window required. Available since the 1970s, mini splits have two parts — an outdoor condenser and an indoor air-handling unit. Mounted in a ceiling or wall, they vent through an exhaust pipe leading outdoors.
How much does it cost to add insulation to a house?
Assuming most homes have at least adequate insulation, the cost to add more should range between $600–$1500.
Can portable air conditioners be vented through windows?
They can be vented through any window using adapter kits — some styles even work with casement and crank out windows — something window air conditioners can’t do.
How to calculate SEER rating?
An air conditioner's SEER rating is calculated by dividing its BTUs or British Thermal Units by the number of watt-hours of energy use. This provides you with the ratio of the heat removal ability of the unit to the amount of energy it takes to remove the heat.
What is SEER rating?
The SEER rating describes the energy efficiency of your HVAC unit, so there's not a specific recommended SEER rating based on home size. The higher the number, the more efficient the unit, but you don't need to choose the unit with the highest SEER rating to have energy-efficient cooling.

STEP 1: Determine how many BTUs of heating and tons of AC you need
The best way to determine the perfect HVAC unit size is to have a Manual J calculation done for your house. The Manual J calculation is the most precise measurement available because it considers factors like:
STEP 2: Decide which unit to buy
Now it’s time to work with an HVAC dealer to learn more about the heating and cooling products they offer. Sometimes the dealer may not have your exact BTU size — but don’t worry. If your BTU requirement is between sizes, simply go with the bigger unit. For example, the Manual J calculation may say you need 25,000 BTUs for cooling.
What Size Air Conditioner Do I Need?
Using an air conditioner on a hot day can make the temperatures more bearable, but only if the air conditioner is big enough to cool the area you want it to. On the other hand, purchasing an air conditioner that is too large for the space may mean you’re spending more money, both on the unit and on the energy it requires to run.
Determining Your BTUs
Air conditioners are sized by the number of BTUs they put out. BTUs stand for British Thermal Units and refer to the amount of energy your air conditioner is using per hour.
Selecting Your Unit
Air conditioners are clearly labeled with the amount of BTUs they need. Consult the following chart to see where your square footage lands in relation to the amount of BTUs. Purchase the unit that best corresponds to the amount of square footage you have.
Variations and Variables
While this chart is used as a general rule of thumb for selecting air conditioner size, variations can occur depending on several variables you need to consider.
Shade and Sun
If the room or house you are cooling is heavily shaded, you may need 10 percent fewer BTUs to cool it. If the house or room is very sunny, however, add 10 percent more BTUs.
Room Occupancy
The more people that use the area you are cooling, the higher the BTUs need to be to compete with body heat. As a general rule of thumb, for every person over an initial 2 people, add 600 BTUs.
Hot Appliances
If the room you are planning on installing an air conditioner in is the kitchen, you need to factor in additional BTUs for the stove, oven, and microwave. Add about 4,000 BTUs to the unit size to cover this.
