An oil furnace to gas conversion is a popular home improvement for Kitsap County residents dealing with high heating oil costs and inefficient older systems. If you're considering this switch, you're likely wondering about the costs, process, and if it's worth the investment.
Here's what you need to know about oil to gas conversion:
Heating with oil in Kitsap County is often expensive and inefficient. Natural gas provides a cleaner, more convenient solution with a consistent fuel supply, eliminating the need for oil deliveries and tank monitoring. The switch also frees up space by removing bulky oil tanks.

For homeowners in Poulsbo, Kingston, or Bremerton, an oil furnace to gas conversion is a smart choice that pays dividends for years. Let's explore the key benefits.
Heating oil prices are volatile and subject to global market swings. In contrast, natural gas prices are more stable. According to the U.S. Energy Information Administration, heating with oil can cost significantly more than natural gas. Recent data shows oil heating averaging around $1,700 for a winter season, while natural gas is under $900. That's a potential annual savings of $800 to $950 or more.
These savings add up, allowing many homeowners to recoup their conversion investment within a few years. If your heating bills are climbing, an inefficient system could be the cause. Learn more about HVAC high energy consumption reasons.
Modern gas furnaces are far more efficient than older oil models. Efficiency is measured by the Annual Fuel Utilization Efficiency (AFUE) rating, which indicates how much fuel is converted to heat. Older oil furnaces often have AFUE ratings of 60-80%, while new high-efficiency gas furnaces achieve ratings of 90% or higher, with some models reaching 98%. The U.S. Department of Energy provides more detail on these ratings.
This higher efficiency means lower bills and better comfort. Gas furnaces provide steady, even heat and operate much more quietly than their oil counterparts. If your current system struggles with uneven temperatures or strange noises, it might be time to review the signs you need an HVAC replacement.
Natural gas burns cleaner than heating oil, producing fewer greenhouse gases. This makes it a better choice for environmentally conscious homeowners in communities like Bainbridge Island.
The convenience is also a major benefit. With natural gas, fuel flows continuously to your home through a pipeline, eliminating the need to schedule oil deliveries or monitor tank levels. Removing the bulky oil tank also frees up valuable space in your basement or yard. Plus, once a gas line is installed, you can convert other appliances like water heaters, stoves, and dryers, potentially saving even more money.
An oil furnace to gas conversion is an upgrade to your entire home comfort experience, offering financial and environmental benefits.
An oil furnace to gas conversion is a comprehensive project. Understanding the key decisions will help you plan with confidence.

While conversion kits exist, a full furnace replacement is almost always the better option, especially for oil furnaces over 10-15 years old. A converted unit is still an aging system and will be less efficient (around 75% AFUE) than a new gas furnace (90-95%+ AFUE). Investing in modern, reliable technology designed for natural gas is the best way to maximize efficiency with HVAC replacement and avoid future repair headaches.
If your home in a rural area like Hansville or Seabeck lacks access to a natural gas line, propane is an excellent alternative for your oil furnace to gas conversion. Both fuels burn cleanly and efficiently. The main difference is delivery: natural gas comes via a pipeline, while propane is stored in a tank on your property.
Here's a quick comparison:
With propane, you can purchase or rent a tank from your supplier. It offers the same flexibility as natural gas for powering other home appliances.
A new gas furnace typically lasts 15 to 20 years, often outliving an old oil furnace. The primary challenge is the upfront investment, which includes the furnace, installation, gas line work, and oil tank removal. However, the long-term fuel savings often result in a payback period of just a few years.
Installation complexity can vary. Connecting to a nearby gas main is simpler than projects requiring extensive ductwork or a new chimney liner. This is why a professional assessment is crucial. Proper sizing is also vital; a furnace that is too large or too small will waste energy and wear out faster. If your current system is struggling, it may be time to consider HVAC replacement and upgrade to a reliable, correctly-sized gas system.
Understanding the upfront investment for an oil furnace to gas conversion is key. Let's break down the expenses and available savings.

The total cost for a conversion varies by home, but here are the typical components:
These costs are offset by annual fuel savings of $800-$950, allowing the investment to pay for itself over time. Inefficient systems are a primary cause of HVAC high energy consumption reasons.
You don't have to cover the full cost of an oil furnace to gas conversion alone. Several programs can reduce your out-of-pocket expenses:
A qualified HVAC professional can help you steer these incentives to maximize your savings. At Eagle Pipe Mechanical, we stay current on available programs to ensure our customers don't leave money on the table. These combined savings can make the conversion more affordable than you might think. For more on system upgrades, see our page on boiler installation services benefits.
An oil furnace to gas conversion is a straightforward process with a qualified team. Here’s what to expect when working with Eagle Pipe Mechanical in Kitsap County.
The first step is to confirm natural gas availability at your address by checking with neighbors or contacting Puget Sound Energy. If natural gas isn't an option, we'll discuss propane as an alternative.
Next, our technicians perform a comprehensive home assessment. We evaluate your existing system, inspect ductwork, and perform a heat load calculation to determine the correct furnace size for your home. Proper system sizing is critical for efficiency and comfort; an oversized or undersized unit will waste energy and wear out prematurely. This assessment ensures we install a system perfectly matched to your needs. Learn more about our approach to Safe Efficient Gas Line Installation.

The installation begins with the utility company running a gas line to your home and installing a meter. Our team then installs the piping from the meter to the furnace.
We then carefully remove your old oil furnace and install the new gas unit, connecting it to your ductwork and electrical systems. Because gas furnace exhaust is different from oil, we will likely need to install a new chimney liner for safe venting. We'll also make any necessary ductwork modifications to optimize airflow. Our Expert Furnace Installation Services are focused on quality workmanship and safety.
Properly decommissioning your old oil system is essential. The oil tank removal process depends on its location. Above-ground tanks are drained, cleaned, and removed. Underground tanks require excavation, after which they are drained, cleaned, and either removed or filled with an inert material, per local codes.
Any leftover heating oil is pumped out and disposed of following strict environmental regulations. We handle the entire process with rigorous safety protocols to protect your property. For more on fuel system safety, read our guide to Identify Gas Line Safety Concerns. Once complete, you can enjoy the benefits of your new gas heating system.
After your oil furnace to gas conversion, proper care ensures your new system lasts its full 15-20 year lifespan.
While gas furnaces are lower maintenance than oil units, they still require regular attention.
To simplify maintenance, consider our HVAC service contracts to keep your system in peak condition.
