Is It a Good Idea To Replace a Furnace But Not the AC in New Jersey?

New Jersey residents know how essential home heating is. When winter temperatures dip below freezing — or harsh cold snaps, high winds, and snowstorms strike — an effective furnace is the difference between comfort and discomfort.

If your home’s furnace needs frequent repairs or isn’t operating at its best, it may be time to consider an upgrade. While you may be tempted to save costs by only replacing a furnace, there are benefits to a total HVAC replacement.

Upgrading your furnace and AC together can save you money in the long run, reduce hassle, and guarantee the best performance from crucial HVAC systems.

How Long Do Furnaces & Air Conditioners Last?

First, it’s important to know the relative lifespan of your heating and cooling systems:

• Gas and electric furnaces have a longer lifespan than most ACs, lasting anywhere from 15 to 20 years with proper maintenance.
• Depending on its make and model, air conditioners can last up to 15 years, requiring a bit more maintenance to stay in working order.
• If your furnace is 15 years or older, you’d be a good candidate for total HVAC replacement and should consider upgrading your AC at the same time.

Benefits of Replacing Your Heating & Cooling Systems Together

While it may seem expensive, performing an AC and furnace replacement together is a smart long-term decision. By pairing a new heating system with a new AC, you’ll enjoy benefits like:

Maximized Cost Savings

The average cost to replace both a furnace and air conditioner is around $13,575, though it can range from $7,350 to $19,800 depending on your household needs. It could be up to $25,050 if you need new ductwork, insulation, and a thermostat.

By replacing both units at once, you’ll save on labor and permit costs and potentially the units themselves. Many providers have ongoing specials and rebate programs to help you save on energy-efficient HVAC systems. Be sure to take advantage of these cost-saving opportunities.

Improved Energy Efficiency

Furnaces or air conditioners may not work best if they’re competing with outdated parts or older technologies. Replacing both systems together makes for a smoother installation, as a technician can assess your home’s heating and cooling capacity as a whole.

The total replacement approach minimizes oversights since both systems will be sized for compatibility.

Optimized Comfort & System Performance

Today’s furnaces and ACs are designed for year-round comfort. A total HVAC replacement offers advanced comfort features, including quieter operation, zoned temperature control, and smart thermostats to help you precisely heat or cool your home.

These features not only enhance your comfort — they guarantee consistent performance for the long haul.

Why Replacing One HVAC System Isn’t Recommended

Replacing only your furnace while keeping an older air conditioner can cause inefficiencies in both systems. A partial replacement can lead to:

• Higher energy bills
• Uneven heating or cooling
• Increased repair costs
• A shorter lifespan for your AC

2025 Freon Mandate

Another reason to replace your AC with your furnace:

Starting in 2025, R-454B, an A2L refrigerant, has become the primary refrigerant used in air conditioning systems, replacing older refrigerants like Freon and Puron.

While repairs for existing units can still be made using stockpiled supplies, Freon and Puron will eventually dwindle, making it more expensive to service older ACs. Replacing your AC now ensures you’re prepared for this change.
