The size of your HVAC unit also impacts your monthly heating and cooling bills. When your unit is too large for the space, it will typically cycle on and off more frequently, leading to higher bills.

| 2 Tons | 901 - 1200 sf | 951 - 1250 sf |
| 2.5 Tons | 1201 - 1500 sf | 1251 - 1550 sf |
| 3 Tons | 1501 - 1800 sf | 1501 - 1850 sf |
| 3.5 Tons | 1801 - 2100 sf | 1851 - 2150 sf |
Here are six tips you can follow:
- Set the Right Default Temperature.
- Keep it at 24 °C, Instead of 18 °C.
- Sealed Rooms & Shut Devices Save Electricity.
- Switch on and Switch off to Save Electricity.
- Fan + AC = Reduced Energy Consumption.
- Regular Servicing and Cleaning Saves Electricity.
An AC that's too small will struggle to keep a room at a comfortable temperature. A model that's too big will cool a room too quickly without removing enough humidity from the air, leaving you cold and clammy. Choose just right and you'll feel just right—and save money, too.
When the cooling system is the proper size, it runs a little bit longer every time it turns on, and during this longer period of running, it provides cooling – and it will dehumidify and provide better comfort in the home. So the bottom line is, bigger is not always better.
But, for the most part, you can tell whether you have an AC or heat pump by:
- Turning on the heat, then checking if the outside unit starts running.
- Looking at the labels on the condenser or indoor air handler.
- Checking for the reversing valve inside the condenser.
The cost to install a 2.5 ton AC unit will range between $3,000 and $4,000.
Simply divide the BTUs by 12,000 to calculate the tonnage of your unit. For example, if your air conditioner is 36,000 BTUs, you have a 3 ton unit. Some manufacturers bury tonnage or BTU information in their model numbers. Look for an even, two-digit number between 18 and 60.
Average cost: $2,800 - $7,770Homeowners on average pay between $3,200 and $5,500 for a central air conditioner unit installation. The main factors that will affect the cost of your AC unit include home's square footage, desired brand, and the SEER rating you choose.
The evaporator coil in an undersized unit may overcompensate for its work load by lowering the temperature below freezing, which will lead to a buildup of ice. In addition to freezing up, an undersized unit may run constantly, but fail to cool your home to the temperature on which the thermostat is set.
If a Heat Pump is Undersized or OversizedDoes it really matter if your heat pump isn't quite the right size? Yes, it really does. That is unless you enjoy paying higher utility costs and extra repair fees. If a unit is too small, it will struggle to produce enough energy to heat and cool your home.
STEP 1: Determine how many BTUs of heating and tons of AC you need
| House Square Footage | BTUs Needed |
|---|
| 1,000 – 1,200 | 21,000 |
| 1,200 – 1,400 | 23,000 |
| 1,400 – 1,500 | 24,000 |
| 1,500 – 2,000 | 30,000 |
Furnace and Air Conditioner size for a detached 2-storey home
| House square footage * | Furnace Output [BTU/hr] | Air Conditioner size [ton] |
|---|
| up to 1300 sq ft | 40,000 BTU/hr | 1.5 ton |
| 1300 to 1700 sq ft | 45,000 BTU/hr | 1.5 ton |
| 1700 to 2500 sq ft | 55,000 BTU/hr | 2 to 2.5 ton |
| 2500 to 3500 sq ft | up to 65,000 BTU/hr | 2.5 to 3 ton |
In the comparison of Carrier Vs. Trane air conditioner in terms of energy efficiency, Trane finds its superiority over the latter one. All the models belonging to the three tiers produced by Trane are more energy-efficient than that in Carrier.

What Size Air Conditioner Do You Need?
| Semi-detached House square footage * | Furnace Output [BTU/hr] | Air Conditioner size [ton] |
|---|
| up to 1500 sq ft | 40,000 BTU/hr | up to 2 ton |
| 1500 to 1800 sq ft | 50,000 BTU/hr | 2 ton |
| 1800 to 2200 sq ft | 55,000 BTU/hr | up to 2.5 ton |
| 2200 to 3000 sq ft | 60,000 BTU/hr | 2.5 to 3 ton |
If a Room sq ft is below 100 sq ft, then go for 0.75/0.8 or 1 Ton AC. That will be enough. 2. If a Room sq ft is between 100-200 sq ft, then go for 1 Ton AC.
When looking for the quick answer to how much air-conditioning power you'll need to adequately cool a 1,300 square foot space, the answer is 23,000 BTUs per hour of air conditioning power. According to the government's Energy Star website, this is the base capacity needed for a 1,200 to 1,400 square feet house.
What size GE room air conditioner is right for you?
| Room Size* | Cooling Capacity |
|---|
| 150–250 Sq. Ft. | 6,000–6,300 BTU |
| 300–400 Sq. Ft. | 8,000–8,900 BTU |
| 400–450 Sq. Ft. | 9,900–10,500 BTU |
| 450–550 Sq. Ft. | 11,600–12,000 BTU |
A higher SEER rating provides greater energy efficiency in certain conditions. A 13 or 14 SEER rating doesn't necessarily mean a unit is inefficient. Most older A/C systems are rated at around 8 or 9, so even the lowest available SEER rated system you buy today will be much more energy efficient.
