- 2,400+ sq ft homes: 4-5 ton systems, $8,100-$12,000

Popular System Options for Warminster Homes
Standard Efficiency Systems (14-16 SEER)
For homeowners seeking reliable cooling at an affordable price point, standard efficiency systems offer excellent value. The Carrier Comfort 13 (model 25HCB3) provides 14 SEER efficiency and includes a 10-year parts warranty. Total installation cost typically ranges from $4,500 to $6,800 depending on home size.
High Efficiency Systems (17-20 SEER)
High efficiency systems are increasingly popular in Warminster due to rising energy costs. The Trane XR16 (model 4TWR6) offers 17 SEER efficiency with variable speed technology. These systems cost $6,200 to $8,900 installed but can reduce cooling costs by 25-35% compared to older systems.
Premium Variable Speed Systems (20+ SEER)
For maximum comfort and efficiency, variable speed systems like the Carrier Infinity 20 (model 25VNA0) provide precise temperature control and exceptional humidity management. Installation costs range from $8,100 to $12,000, but utility rebates of up to $500 are often available.
