Frequently asked questions
How much does AC repair cost in NJ?
AC repair in New Jersey typically costs $150-$600 for common issues like refrigerant recharge, capacitor replacement, or thermostat repair. Major repairs like compressor replacement can run $1,500-$3,000. We provide upfront pricing before starting any work.
How often should I service my HVAC system?
We recommend professional HVAC maintenance twice a year — once in spring for your AC and once in fall for your heating system. Regular maintenance extends equipment life by 5-10 years and can reduce energy bills by 15-25%.
What size HVAC system do I need for my home?
HVAC sizing depends on your home's square footage, insulation, number of windows, and ceiling height. A system that's too small won't keep up; too large will short-cycle and waste energy. Our technicians perform a Manual J load calculation to determine the exact right size.
