Furnace Installation & Replacement in Hoboken, NJ

Frequently Asked Questions

What Are the Key Signs That My Old Furnace Needs to Be Replaced Rather Than Repaired?

If your furnace is over 15 years old, replacement is typically more cost-effective as its efficiency is declining, leading to consistently higher energy bills. Frequent and expensive repairs are a major indicator; experts recommend replacement when the repair cost exceeds 50% of the cost of a new unit. Any sign of a cracked heat exchanger, often detectable by a sickly sweet smell or yellow flame, necessitates immediate replacement due to the grave risk of carbon monoxide leakage. Lastly, if the furnace struggles to keep your home comfortably and evenly warm, despite repairs, it is likely undersized or too worn out to meet your heating needs.

How Long Does a Typical Furnace Installation or Replacement Process Take?

A standard furnace installation or replacement typically takes an HVAC professional between four to eight hours to complete on average. The time frame can vary based on whether the installer needs to make modifications to the existing ductwork, gas line, or venting system for compatibility. Replacing an electric furnace is usually faster than replacing a gas furnace, which requires more complex venting and gas connections. It is generally best to allocate a full day for the installation to ensure the technician can thoroughly complete the setup and conduct the necessary system testing and commissioning.

What Do I Need to Consider When Getting a New Furnace?

The most crucial factor is determining the correct size of the furnace, measured in British Thermal Units (BTUs), through a professional load calculation of your home. You should consider the Annual Fuel Utilization Efficiency (AFUE) rating, aiming for a rating of 90% or higher to maximize energy savings and lower your heating bills. Additionally, select a furnace type (gas, electric, or oil) that aligns with your local fuel availability and cost structure. Finally, inquire about the warranty coverage, particularly for the heat exchanger, and verify that the unit is compatible with modern smart thermostats.

How Can I Prepare My Home for a Furnace Installation?

The most important step is to clear the area around your existing furnace, ensuring the technicians have ample space to remove the old unit and install the new one. Clear a pathway from your door to the furnace location, removing any boxes, clutter, or personal items that could obstruct movement. Secure any pets in a separate room and ensure you are home and available to answer any questions the technicians may have during the process. Before they arrive, it is also wise to check for clear access to the electrical panel and any gas or fuel shut-offs.

What Kind of Maintenance Does My New Furnace Need?

The most essential maintenance task you can perform yourself is regularly replacing or cleaning the air filter, ideally every one to three months during the heating season. You must schedule professional maintenance and an inspection at least once per year, typically in the early fall, to ensure the unit is running safely and efficiently. A technician will clean the burners, check the electrical connections, inspect the heat exchanger for any cracks, and test the carbon monoxide levels. This annual service is typically required to maintain your furnace manufacturer's warranty and to extend the system's lifespan.
