The national median for a 3 ton central AC installation is $10,800, ranging from $7,400 on the low end to $14,900 on the high end. Mini split systems run $4,200 to $6,100 per zone. Full ducted replacement on a 2,000 square foot home averages $18,200. Regional variation is significant: Hawaii, California and the Northeast run 20 to 35 percent above the national median. Federal tax credits cover up to $2,000 for qualifying heat pump installations in 2026.

Twice per year. Cooling tune up in spring, heating tune up in fall. In coastal climates like Hawaii and Florida, saltwater corrosion accelerates failure, so quarterly coil rinses are recommended. A service contract typically pays for itself after preventing one emergency call.

The category average for Roofing is 43 out of 100 as of April 2026. Scores above 70 mean the business reliably appears in ChatGPT, Claude and Perplexity answers for queries like "best AC repair near me." Below 30 means the business is effectively invisible to AI search, which now drives 18 percent of local lead volume.

We compute a Business Health Score from six inputs: Google reviews and response rate (40 percent), market share in the local city (20 percent), job flow signals (10 percent), financial health proxies (20 percent), and Kai operator activity (10 percent).

Look at four things: (1) Google rating and review count, weighted equally. Four stars with 600 reviews beats 4.9 stars with 12. (2) Response rate to reviews, especially negative ones. Below 60 percent is a red flag. (3) Years in business and licensing. In most states you want a licensed journeyman with at least 5 years operating. (4) Emergency availability if you need after hours service.

Usually yes. National median is $340 per year and typically includes two tune ups, priority scheduling, 10 to 15 percent discount on parts and repairs, and a labor warranty. One emergency call prevented usually covers the entire annual cost. Skip the contract if your system is under 5 years old and still under manufacturer warranty.
