A furnace replacement project in New Jersey usually costs $4,500–$12,000. In Pennsylvania, you can expect to pay $4,000–$9,000 for a new furnace system installed at your residential or commercial facility. These figures include everything: equipment cost, installation charges, and permit fees. However, the exact price may vary depending on square footage, equipment efficiency, and the service fees of the company you hire for furnace installation service in Pennsylvania or furnace services in New Jersey.
Commercial furnace installation projects cost more than residential projects due to increased complexity, equipment rentals, and more sophisticated control systems required at business facilities. This blog lists prices for new furnace installations by various factors, listing the verified cost ranges as of 2026.
Furnaces have four main types by the fuel they consume to generate heat. As fuel sources vary, the underlying mechanism to generate heat energy and the equipment structure vary greatly, which directly influences the final quote.

While you can replace your existing, outdated furnace for as low as $4,000, many homeowners and small business owners still find it a bit outside their affordability range. To help them, here are some tips to make furnace replacements affordable.
No need to choose a larger-sized furnace if you own a small place. If you do so, be ready to accept surprising energy bills and frequent equipment wear and tear as well. The best practice is to get a Manual J load calculation and then choose a furnace that is the right size and efficiency to meet your heating needs.
Feel free to contact Lehigh HVAC for a load calculation and site survey.
Don’t accept the quote from a single contractor. Get quotes from at least 3 to 5 reliable service providers or HVAC companies and then compare their quotes. Analyze their prices, project deadline, services included, and overall credibility. This will help you choose the right service provider.
