Installing central air conditioning is a complex process that involves several factors, such as the type of system, the size of the unit, and the condition of the existing HVAC system. The cost of installation also depends on whether ducts need to be replaced or installed. The main cost factors are the cooling capacity (BTU) or size of the central air conditioning unit, the SEER or system efficiency index, and factors related to your home, such as the location of the air conditioning unit. As an expert in HVAC systems, I can tell you that unfortunately, most contractors do not take the time to perform a manual J calculation and, to be “safe”, they tend to oversize their central air system, resulting in higher installation and operating costs.
If only the air conditioning unit is being replaced, labor costs are lower than if ducts need to be replaced. In some areas, permits are required to install or modify an HVAC system, so it is always recommended to hire a professional. When it comes to cost, it is important to note that the average cost of installing a 2-ton air conditioning unit will be lower than the national average cost of installing a 3-ton air conditioning unit, and the cost of installing a 4-ton air conditioning unit will be higher than the national average. When considering an AC installation for your 1500 sq ft house in Florida, it is important to take into account all of these factors.
It is best to consult with an experienced HVAC contractor who can help you determine the best size and type of AC unit for your home. They can also provide you with an accurate estimate of installation costs and help you find ways to save money on your AC installation.
