Our team provides professional AC replacement services in Union County, NJ, and throughout Central New Jersey.

Should You Repair or Replace Your AC?
Not sure whether to repair your current system or invest in a new one? Chapman Bros. helps you make the right call based on your specific situation — not on upselling. Use this framework as a starting point:
- System age: If your AC is 12–15+ years old, replacement is usually more cost-effective than repeated repairs.
- The 50% rule: If the repair cost exceeds 50% of the price of a new system, replacement is the smarter investment.
- SEER rating: Older units often run at 8–10 SEER. Modern systems start at 14–16 SEER and high-efficiency models reach 20+ SEER — cutting cooling costs by 30–50%.
- Frequent breakdowns: If you’re calling for repairs every season, a new system will save money and stress.
- R-22 refrigerant: Systems using the now-phased-out R-22 refrigerant are increasingly expensive to service and should be replaced.
Still not sure? Our technicians will give you an honest assessment with no pressure. You can also start with an AC inspection or schedule a repair diagnostic to understand your options.
