Furnace Repair You Can Count On
When your furnace stops working, you need a company that answers the phone and shows up fast. Our technicians are experts at diagnosing and repairing the full range of furnace problems New Jersey homeowners face:
- Furnace won't turn on or won't produce heat
- Short cycling or constantly running
- Blower motor or fan problems
- Faulty ignitor, flame sensor, or pilot light
- Cracked heat exchanger (a critical safety issue)
- Clogged filters and restricted airflow
- Thermostat and control malfunctions
Every repair starts with a thorough diagnosis and an upfront quote. You'll always know the price before we begin.
Furnace Installation & Replacement
If your furnace is beyond economical repair, a new high-efficiency system can dramatically lower your energy bills while keeping your home more comfortable. NJ HVAC Service makes replacement easy and stress-free.
We start with a free in-home assessment to properly size your new furnace — an oversized or undersized unit wastes energy and shortens equipment life. We then walk you through your options across efficiency levels and budgets, handle the entire installation professionally, and make sure everything is running perfectly before we leave. Ask us about available manufacturer rebates and New Jersey energy-efficiency incentives that can reduce your cost.
Gas vs. Oil Furnaces
New Jersey homes run on both gas and oil furnaces, and we service and install both. Natural gas furnaces are common, efficient, and typically lower-cost to operate, while oil furnaces remain widespread in many older NJ homes and can deliver powerful, reliable heat. If you're considering an oil-to-gas conversion, we can advise on whether it makes sense for your home and handle the project from start to finish.
