What Affects the Cost?
System Size (Tonnage)
HVAC systems are sized in tons (1 ton = 12,000 BTU). Most NJ homes need 2-5 ton systems. Proper sizing is critical - oversized or undersized systems waste energy and wear out faster.
Efficiency Ratings
Higher SEER (cooling) and AFUE (heating) ratings cost more upfront but save on utility bills. In NJ, aim for 16+ SEER and 90%+ AFUE for best long-term value.
Existing Ductwork
If your ducts are in good condition, replacement costs less. Old, leaky, or undersized ducts may need replacement, adding $2,000-$6,000 to the project.
Brand and Features
Premium brands (Carrier, Trane, Lennox) cost more but often offer better warranties and reliability. Features like variable-speed motors and smart thermostats add cost but improve comfort and efficiency.
Money-Saving Tips
- 1Get at least 3 quotes for any installation - prices vary significantly between contractors
- 2Ask about rebates - NJ utilities and manufacturers often offer efficiency rebates
- 3Don't just go with the cheapest quote - installation quality matters more than equipment brand
- 4Request a Manual J load calculation for new installations - this ensures proper sizing
- 5Consider a maintenance agreement - annual tune-ups extend system life and catch problems early
- 6Check contractor licensing - NJ requires HVACR licenses for this work
- 7Ask about financing options - many contractors offer 0% financing for new systems
- 8Time your purchase - spring and fall often have better pricing than peak summer/winter
When to Hire a Professional
- •System isn't heating or cooling effectively
- •Unusual noises, smells, or high energy bills
- •System is 15+ years old and needs significant repair
- •Uneven temperatures between rooms
- •AC uses R-22 refrigerant (being phased out)
- •You're building new or renovating
- •Current system can't keep up with extreme weather
- •Visible mold, rust, or deterioration on equipment
Red Flags to Watch For
- •Quote without doing a load calculation
- •Recommending a much larger system than others
- •Much cheaper than other quotes (may use inferior equipment or cut corners)
- •High-pressure sales tactics or "today only" pricing
- •Won't provide references or show licensing
- •Asking for full payment upfront
- •No written warranty or contract
- •Can't explain the equipment or installation process
Frequently Asked Questions
How often should I replace my HVAC system?
AC units typically last 15-20 years, furnaces 20-25 years. However, if repair costs exceed 50% of replacement cost, or your system uses R-22 refrigerant (phased out), replacement often makes more sense. Newer systems are significantly more efficient, potentially saving $500+ annually on energy.
What size system do I need?
A proper Manual J load calculation considers your home's size, insulation, windows, and orientation. As a rough guide, NJ homes need about 1 ton per 500-600 sq ft, but many factors affect this. Oversized systems cycle too frequently, waste energy, and don't dehumidify properly.
Should I repair or replace my AC?
Consider replacement if: the system is 15+ years old, uses R-22 refrigerant, needs a major repair (compressor), or repair costs exceed 50% of replacement. Also consider that new systems are 30-50% more efficient, which can offset the higher upfront cost over time.
What's the best brand?
Premium brands like Carrier, Trane, and Lennox are reliable but cost more. Mid-tier brands like Rheem, Ruud, and Goodman offer good value. More important than brand is proper sizing, quality installation, and regular maintenance. A well-installed mid-tier system outperforms a poorly installed premium one.
