Air Conditioning Replacement Cost in Houston

Air Conditioning Replacement Cost in Houston

AC systems have come a long way in the last few decades. When your residential or commercial HVAC system is well maintained and kept in good condition it can last you for more than a decade. Estimating a new air conditioner’s cost will take looking at multiple factors.

Listed below are some things to take into consideration when speaking to an AC technician about the installation of a central air conditioner, taken from Bob Villa:

Installation: Total central AC unit costs are strongly influenced by installation costs, which vary from one project to the next. If a new unit needs to be installed without updating existing ductwork, labor costs have a lower average of $1,250 to $2,300. For complete ductwork and unit installation, most homeowners spend an average of $2,550 to $3,600. The actual unit is an additional cost, and the price depends on the type of unit.

System Type: For most regions, a central AC unit is the popular choice to pump cool air to the entire house, and it’s often combined with the heating unit as a complete HVAC unit. If only an air conditioning unit is needed, professionals can install ductless split systems for an average price of $2,000 to $14,500. For cooler regions where a sunny day overheats only a single room, a window AC unit can be installed for $150 to $500. Portable units are another convenient option that are similarly priced to window AC units.

System Size: When it comes to AC units, bigger isn’t necessarily better. Central AC units measure their output in BTUs (British thermal units) and are available in 1.5- to 5-ton capacities. To calculate the AC unit size that you need, multiply the square footage of your home by 18 (because it takes about 18 BTUs to cool 1 square foot). If you have high ceilings, multiply the number by 1.25. Then, divide that number by 12,000 to get the tonnage required.

SEER Rating: The SEER (seasonal energy efficiency ratio) rating influences the price of an air conditioner and determines how effectively a unit operates throughout the season. Units with a higher SEER rating may cost more up front, but they’ll have lower operating costs. According to HomeAdvisor, all AC units must have at least a 13 SEER rating. If your unit was installed before 2006, consider updating it to take advantage of the new energy-saving efficiency.

Home Size: A good estimate to calculate central AC unit costs is $2.50 to $6 per square foot. Installing a central AC unit in a hotter climate will cost more since a more powerful unit with higher-than-normal efficiency ratings is needed to avoid burning out quickly. A unit with a SEER rating of 16 to 18 will work for most climates. Depending on the SEER (seasonal energy efficiency ratio) rating, you can expect a 1,200-square-foot home to cost between $3,000 and $4,000 for AC installation.
