The unit uses R-22 refrigerant: R-22 refrigerant is being phased out, making it increasingly expensive and difficult to obtain. If your unit uses R-22, replacement is a good option.
Energy bills are high: An older, less efficient unit will consume more energy, resulting in higher energy bills. A new, high-efficiency unit can significantly reduce your energy consumption.
You want to improve energy efficiency: Newer AC units have higher SEER ratings, making them more energy-efficient and environmentally friendly.

Repair might be a viable option if:

The unit is relatively new (less than 10 years old): If your unit is relatively new and the repairs are minor, repairing it might be the more cost-effective option.
The repairs are infrequent and inexpensive: If the repairs are relatively infrequent and the cost is low, repairing the unit might be a reasonable solution.

It's always a good idea to get a professional opinion from an HVAC technician. They can assess the condition of your unit and provide recommendations based on your specific situation.

Question 4: What size AC unit do I need for a 2000 sq ft house?

Determining the correct size AC unit is crucial for optimal performance and energy efficiency. The size of an AC unit is measured in BTUs (British Thermal Units). For a 2000 sq ft house, you'll typically need an AC unit with a cooling capacity of 30,000 to 40,000 BTUs. This translates to 2.5 to 3.5 tons (1 ton = 12,000 BTUs).

However, several factors can influence the ideal BTU rating:

Climate: Homes in hotter climates will require larger AC units than those in cooler climates.
Insulation: Well-insulated homes require smaller AC units.
Window Size and Orientation: Homes with large windows or windows facing south or west will require larger AC units.
Ceiling Height: Higher ceilings increase the volume of air to be cooled, requiring a larger AC unit.
Number of Occupants: More occupants generate more heat, requiring a larger AC unit.
Sun Exposure: Homes with significant sun exposure will require larger AC units.

It's best to consult with an HVAC professional to perform a load calculation. This calculation takes into account all of the factors mentioned above to determine the precise BTU rating needed for your home.
