Good Questions

Heating FAQs

How much does a new furnace cost in NJ?

It depends on the furnace type and size, your home's layout and ductwork, and the efficiency level you choose. ICS sizes each system to the home rather than just swapping a box, and gives you a clear, itemized quote up front — with financing available. Call (866) 749-6331 for a free estimate.

How long does a furnace last?

With proper installation and annual maintenance, most gas furnaces last 15 to 20 years and boilers often longer. Heat pumps run about 12 to 15 years. Skipping maintenance or running an oversized system shortens that significantly — our tune-up plans help you get the full lifespan.

What are the signs my furnace needs repair?

Watch for unusual banging, rattling, or squealing sounds, a yellow burner flame instead of blue, weak or uneven heat, short-cycling, rising energy bills, or a burning smell when it runs. If you notice any of these, have it inspected before it becomes a larger failure.

Should I repair or replace my heating system?

As a rule of thumb, if your furnace is over 15 years old, needs a repair costing a large share of replacement, or is steadily driving up your bills, replacement usually pays off. If it's newer and the fix is minor, repair makes more sense. We give you an honest recommendation either way.

Do you offer 24/7 emergency heat repair?

Yes. A heating failure during a New Jersey winter can't wait, so ICS provides 24/7 emergency heating repair across Northern New Jersey and New York City. Call (866) 749-6331 any time.

How often should I service my heating system?

At least once a year, ideally in the fall before heating season. Annual maintenance keeps the system efficient and safe, protects your warranty, and catches small problems before they leave you without heat on the coldest night.

Do you install heat pumps and offer electrification?

Yes. ICS are certified cold-climate heat pump specialists. A heat pump delivers efficient heating and cooling from one system and may qualify for significant New Jersey rebates — ask about current programs when you request an estimate.

What heating systems do you service?

We install, repair, and maintain gas and electric furnaces, boilers, heat pumps, and ductless mini-split systems for both residential and commercial properties across Northern New Jersey and New York City.
