- Willingness to perform detailed load calculations
Request quotes from at least three reputable companies, comparing not just bottom-line prices but also equipment specifications, warranty terms, and included services. For a 1,900-square-foot home, ask specifically about strategies for maintaining consistent comfort throughout the space.
Consider timing your replacement strategically. If your current system is still operational, scheduling installation during spring or fall can save 10–15% compared to peak summer and winter pricing.
The Installation Process
Professional HVAC contractors follow a step-by-step process to ensure your new HVAC installation goes smoothly. We detail these steps below.
Home Assessment
Before installation, your contractor should conduct a comprehensive evaluation of your home, including the following:
- Checking electrical capacity
- Evaluating insulation and air sealing
- Inspecting existing ductwork for size and condition
- Measuring and analyzing your living spaces
- Performing load calculations to determine proper system sizing
This assessment forms the foundation for equipment recommendations and installation planning.
Installation Day
The typical installation process includes the following:
- Preparation and removal: Technicians will protect your home, recover refrigerant from your existing system, disconnect electrical connections, and remove both indoor and outdoor components.
- New system installation: They’ll position the outdoor unit on a level surface, install the indoor coil with your furnace or air handler, connect refrigerant lines, and install proper drainage and electrical connections.
- System commissioning: After pressure testing for leaks and evacuating the system, they’ll charge it with refrigerant according to the manufacturer’s specifications. They’ll test electrical components, verify proper airflow throughout your home, and confirm the system is operating correctly.
- Final setup: They’ll program your thermostat, demonstrate system operation, explain maintenance requirements, and provide documentation for all installed equipment.
For a 1,900-square-foot home, this process typically takes six to 10 hours for an air conditioner replacement, or eight to 12 hours if replacing both the AC and furnace simultaneously.
How Does My Location Affect Cost?
Your geographic location affects several aspects of your air conditioner replacement. Climate conditions influence both system selection and sizing requirements. Homes in hot, humid regions typically need stronger dehumidification capabilities, while those in hot, dry areas benefit from systems optimized for high-temperature operation.
Labor costs vary significantly by region, ranging from $1,213 in rural areas to $2,763 in metropolitan and coastal markets. Regulatory requirements also differ, with minimum efficiency standards of 13.4 SEER2 in northern states and 14.3 SEER2 in southern and southwestern states since 2023.
For 1,900-square-foot homes in regions with extreme temperature variations, consider dual fuel systems that combine the efficiency of heat pumps with the heating power of gas furnaces. These systems automatically switch between energy sources based on outside conditions to optimize both comfort and operating costs.
Editor’s note: Although this article discusses SEER2 ratings in the context of AC and gas furnace split systems, SEER2 applies only to the air conditioning portion. SEER2 measures cooling efficiency and does not apply to the heating performance of gas furnaces.
FAQs About Air Conditioner Costs for a 1,900-Square-Foot Home
How do I know if my air ducts are properly sized?
Ductwork sizing becomes particularly important in 1,900-square-foot homes, where longer runs and multiple branch lines can create airflow challenges. Signs your ducts may be undersized include rooms that never reach comfortable temperatures, significant temperature differences between rooms, whistling noises from registers, or high system pressures that cause your equipment to cycle frequently. During your AC replacement, ask your contractor to evaluate your existing ductwork using airflow measurements and pressure testing to ensure optimal performance.
How does my ceiling height affect air conditioner selection?
Standard cooling load calculations assume 8-foot ceilings, but many 1,900-square-foot homes feature vaulted, cathedral, or higher-than-standard ceilings that significantly increase the volume of air requiring conditioning. For every foot of ceiling height above 8 feet, you should generally add 10–15% to your cooling capacity requirements.
What HVAC warranties should I look for?
Warranty coverage represents an important but often overlooked aspect of air conditioner replacement. For a 1,900-square-foot home where system costs are substantial, comprehensive warranty protection provides valuable peace of mind.
Equipment warranties typically include:
- Compressor warranty: This critical and expensive component should carry a warranty of at least 10 years, with premium brands offering 12-15 years or even lifetime coverage on high-end models.
- Parts warranty: Look for 10-year coverage on all other components, including coils, fans, and electronic controls.
- Labor warranty: Manufacturer warranties typically cover parts only, but contractors often provide separate one- to three-year labor warranties. Extended labor warranties (five to 10 years) are available for additional cost and merit consideration for larger homes with more complex systems.
What are common installation mistakes to watch for?
Several key installation factors can impact the performance and longevity of an air conditioner. These include ensuring the unit has the correct sizing using a Manual J calculation. The same applies to ductwork since this allows adequate airflow. Other important aspects include maintaining the correct refrigerant charge, addressing ductwork leaks (which can result in a significant 20–30% loss in system efficiency), and ensuring proper condensate drainage to prevent water damage.
