Plan the Supply for the Appliance and the Home
A nearby gas pipe does not confirm that a new appliance can be connected to it. Existing demand, the route, and the selected equipment all belong in the installation plan.
-
Know the Appliance Requirements
The model and intended location help define the project. Supply needs can differ significantly when changing from one appliance type to another.
-
Consider the Shared Supply
The existing gas system may serve several appliances. A new connection needs review in that wider context, including any utility coordination.
-
Plan the Route Early
Access through the home and any outdoor work affect the scope. Resolve the proposed route before finishes or equipment placement are finalized.
What Shapes Your Gas Line Installation
We identify the proposed piping work and the related decisions that affect the project.
Route & Access
Plan the route between the supply and appliance, including access to indoor or underground piping. North handles excavation and restoration needed for the agreed gas line project.
Project Coordination
North handles required permits, inspections, and utility coordination as part of the agreed work. We explain the steps needed for your project without a separate charge for that handling.
Installation & Checks
Complete the agreed piping work and applicable testing before handoff. Explain what has been completed and any remaining steps before the appliance can be used.

On Time and Respectful
I had an issue with my heat pump, and North Heat & Air fixed it. This is a company that is well worth your time and money - highly recommended! They were on time, respectful of my property, and kept everything clean during the visit. Their communication was excellent before, during, and after the service. The pricing was fair, and I was able to pay easily online by credit card. I’ve done the research for you - just book an appointment with them.
Prompt, Clear Communication
North Heat & Air was fantastic. Communication was always prompt and clear. I had a new forced air heat pump installed replacing an old oil furnace. The price was very fair and the work was professional. I would highly recommend them.
Expert Furnace Installation
I got three bids, and North Heat & Air offered an excellent price on a Trane furnace. More importantly, I was impressed with the team - they even checked whether my old furnace could be saved first. The new furnace was installed expertly in half a day, works flawlessly, and they were able to fit me in quickly. I couldn’t be happier.
Installed in One Day
Very happy with my new system, they arrived on time and spent 11 hours installing everything in one day so we didn’t have to go a night without heat. Got multiple bids and they were very reasonable. Would not hesitate to recommend to friends and family.
Great Value for a Heat Pump
Highly recommended. I needed a new heat pump and air handler, got 5 bids, and North Heat & Air offered one of the best prices with a much better SEER 18 system. They came out 2 days later and completed the full installation in one day, which was a huge help during winter. The team was knowledgeable, professional, and walked me through everything I needed to know for operation and maintenance. Can’t go wrong.
Smooth and Stress-Free
North Heat and Air did a great job installing my new furnace and AC. The team was professional, on time, and easy to work with. They explained everything clearly and made the whole process smooth and stress-free. The system works great and my home is much more comfortable. Highly recommend!
Exceeded Our Expectations
We wanted an upgrade for our central AC unit. They had the best price and came highly recommended. Arrived on time and worked tirelessly throughout the day to remove the old unit and install the new one. The work they did exceeded our expectations.

From Appliance Plan to Gas Connection
The scope and price are agreed before piping work begins.
-
Arrange a Free Assessment
We review the intended appliance, its location, and the existing supply arrangement. The visit and installation estimate are free.
-
Approve the Route & Price
Review the piping, appliance connections, access, and restoration included in your project. You approve the complete agreed price before installation starts.
-
Install & Review Completion
We complete the agreed work and checks, then explain the handoff. We wear shoe covers when entering your home and clean up after the job.
Plan Your Gas Line Before Installation Day
Start with a free assessment of the appliance location and existing supply.
Add a Gas Connection With a Complete Plan
A new furnace, fireplace, water heater, or other gas appliance may need a new supply line or changes to an existing one. The work should be planned around the appliance’s requirements and the home’s gas system, with a route that can be installed and serviced appropriately.
North Heat & Air assesses gas line installation projects in Seattle and surrounding communities. Our team is based in Everett. The visit and estimate are free, and you approve the installation price before work begins.
Choose the Appliance Before Finalizing the Connection
An appliance’s fuel requirements and rated demand help determine the supply it needs. Bring the model information if you have already selected equipment. If you are still comparing models, explain the project and intended location so the gas line can be considered before the purchase.
A change to a tankless water heater, for example, can change the supply requirements compared with the equipment it replaces. The presence of an existing connection does not mean it suits every new appliance. Our water heater installation service can help coordinate that wider project.
Review Demand Across the Existing System
The pipe route, its length, and other appliances sharing the supply matter when planning an addition. Meter or supply limitations may also require utility involvement. These are professional assessment questions; guessing from pipe appearance or simply copying a neighboring connection is not a sound installation plan.
Tell us about other planned gas appliances even if they will be installed later. That information helps avoid treating today’s project in isolation. We handle the utility coordination, required permits, and inspections for the agreed project, with no separate charge for that handling.
Understand the Route and Access Work
Moving a gas appliance across a room can require a different route and more work than connecting one in its existing location. Access through finished walls, floors, a crawlspace, or an exterior area affects both scheduling and cost. Identify places that will be remodeled and areas you want to keep accessible.
We install natural gas and propane lines, including indoor and underground piping. North handles the excavation and restoration needed for our project. The assessment identifies that work so the agreed price reflects the complete scope. For a fireplace installation, the supply route needs to fit the appliance location and the rest of the fireplace plan.
Compare Complete Installation Scopes
Gas line cost depends on appliance requirements, routing, access, materials, and related project needs. A short, accessible branch differs from a line that must cross finished spaces or serve a relocated appliance. The estimate includes the agreed piping, appliance connections, testing, and associated excavation or restoration. You can review these details before approving the price. Financing at 0% APR for 12 months is available for the gas line project, subject to credit approval and offer terms.
Our own technicians complete the installation and testing before handoff. North is licensed, bonded, and insured. We provide result photos and written findings so you know what was completed. Never connect or modify gas piping yourself, and do not restore a utility-shut gas supply on your own.

Our technicians wear shoe covers on entering the home and clean up after their work. We provide a two-year workmanship warranty covering issues with work performed by North. Request a gas line installation estimate or call (425) 550-2203.
If you suspect a gas leak, leave the area and call your gas utility or 911 from a safe location. Do not wait for an installation appointment or use switches and devices near the suspected leak.
Frequently Asked Questions
We can assess a new appliance connection and explain the proposed installation. Share the appliance model, fuel type, intended location, and any available information about the existing gas setup.
