HVAC Services in Union County & Central NJ
AC installation, furnace repair, heat pumps, and 24/7 emergency heating and cooling service.
Your HVAC system keeps your family comfortable year-round. When it stops working, you need someone who diagnoses the actual problem and fixes it. Not someone who tells you the whole system needs replacing when a $200 part would solve it. Vanguard Service NJ provides honest HVAC service for homeowners across four NJ counties.

HVAC Questions
Do you install AC systems in Union County, NJ?
Yes. Vanguard Service NJ installs central AC, heat pumps, and ductless systems for homes across Union County and nearby Central NJ towns. We evaluate the home's size, ductwork, electrical needs, and comfort goals before recommending equipment.
How much does HVAC repair cost in NJ?
Minor fixes like a capacitor replacement usually run $150 to $650, and major repairs like a compressor or heat exchanger run $1,200 to $5,500. We find the cause first and give you a written price before any work begins.
How much does a new AC unit cost in New Jersey?
A new central air conditioning system with standard-efficiency equipment typically costs $4,500 to $13,000 installed, depending on the size of your home. High-efficiency and variable-speed systems cost more, up to about $24,000 in larger homes. We help you choose the right system for your home's size and layout.
How often should I service my HVAC system?
Your HVAC system should be serviced twice a year: once in spring for your air conditioner and once in fall for your heating system. Regular maintenance extends equipment life, prevents breakdowns, and keeps your system running efficiently.
Is it worth repairing a 15-year-old AC unit?
Many central AC systems last about 10 to 15 years, and some last longer with regular maintenance. If your 15-year-old unit needs a repair costing more than about a third of the price of a new system, replacement is usually the better investment. Newer units are significantly more energy-efficient, which means lower monthly bills.
What is a heat pump and is it worth it in NJ?
A heat pump heats and cools your home using one system by transferring heat rather than generating it. In New Jersey's climate, modern cold-climate heat pumps work efficiently even in below-freezing temperatures. Compared with oil, propane, or electric baseboard heat, a heat pump usually costs less to run. Compared with natural gas, the savings depend on local gas and electric rates. See our heat pump installation cost guide for price ranges.
Do I need a permit for HVAC installation in NJ?
Many HVAC installations and equipment replacements in New Jersey need a permit and an inspection from the local construction office. Vanguard Service NJ handles permits and inspections where they are required for your job.
