Replace Your Sewer or Water Line Without Destroying Your Property
Trenchless pipe replacement for Issaquah, Snoqualmie, and East King County homes. No trenches. No destroyed landscaping or parking lots.
Furnace installation and repair by a crew licensed for every trade it touches
Noble Plumbing, Heating & Cooling installs, replaces, and repairs gas and electric furnaces across the Snoqualmie Valley and the Eastside. Our HVAC division is led by a 22-year mechanical trades veteran who holds gas, refrigeration, electrical, and plumbing licenses. That matters for furnaces specifically: a furnace touches gas, venting, electrical, and often the water heater's flue, and most problems live where those systems meet.
Whether you need a no-heat call this week or you're planning a replacement before winter, you'll get upfront pricing, a clear explanation of what we found, and work that's done right the first time.
Furnace services
Furnace Installation
New high-efficiency gas and electric furnaces, sized to your home with a proper load calculation rather than a guess based on the old unit. We handle permits, venting, gas line connections, and combustion testing, and we'll tell you if a heat pump would serve you better before you commit.
Furnace Replacement
Most furnaces last 15 to 20 years. If yours is in that range and needs a major repair, replacement is usually the better money. We'll show you the math, remove the old unit, and have the new one running the same day in most homes.
Furnace Repair
Ignition problems, short cycling, blower failures, cracked heat exchangers, thermostat faults. We diagnose why the system failed, not just what part stopped working, so you're not calling us back for the same thing in February.
Furnace Maintenance
An annual tune-up before heating season catches worn igniters, dirty burners, and failing capacitors while they're cheap to fix. It also keeps your manufacturer warranty valid. Learn about our maintenance plans →
Should you repair or replace your furnace?
We use the same trenchless methods for both.
The approach just adapts to what we’re working on.
Replace it when
It's over 15 years old and needs a major repair
This is the second major repair in two years
The heat exchanger is cracked (a carbon monoxide risk, not a judgment call)
Energy bills have been climbing with no other explanation
You're adding air conditioning anyway, which opens the door to a heat pump
Repair it when
It's under about 12 years old
The repair costs less than a third of a replacement
The heat exchanger is sound
This is the first significant repair, not the third
No Parking Lot Destruction Required
Furnace and heat pump replacement in Issaquah home
FROM THE FIELD
The Problem
When a local church in Issaquah reached out to Noble, they weren't dealing with a full-blown emergency yet. Their 2" galvanized water main had been in the ground since the 1960s, and they knew it was only a matter of time before something went wrong. Rather than wait for a failure at the worst possible moment, they called us to talk about options.
The catch? The water main ran under their parking lot. A traditional open-cut replacement would have meant tearing up a significant portion of that asphalt, which is costly, disruptive, and a headache for a busy church property. That's exactly why they chose Noble: we could get it done with trenchless technology and keep the parking area intact.
What We Did
Replaced the aging furnace with a new [brand/model] gas furnace paired with a Midea heat pump and indoor air handler, so the heat pump carries most of the heating season and the furnace takes over on the coldest nights. New line set, a dedicated 240-volt circuit with a disconnect at the unit, pad-mounted outdoor unit, condensate drain, thermostat setup, combustion and refrigerant testing, permit and inspection.
The Result
Aging galvanized water main fully replaced with modern PEX-a
Secondary leak repaired before it became its own emergency
Parking lot left exactly as we found it
Church avoided a reactive, high-cost emergency replacement down the road

What a Noble furnace install includes
Sized with a load calculation, not a guess.
Oversized furnaces short-cycle, wear out early, and heat unevenly. We size the new unit to your home's actual heat loss, not to whatever the last contractor put in.
Venting, gas, and electrical by one licensed crew.
No subcontractor handoffs. The same technicians run the gas line, set the venting, wire the unit, and pull the permit, and they're licensed for each of those trades.
Commissioned before we leave.
We verify gas pressure, temperature rise, carbon monoxide, and airflow, then walk you through the thermostat and the filter. You get a system that's tested, not just connected.
Signs your furnace needs attention
Call for a repair if you notice
Short cycling
the furnace turns on and off every few minutes
Multiple Slow Drains
When the kitchen, bathroom, and toilets all drain slowly, the problem is your main line.
A yellow or flickering burner flame
Instead of a steady blue
Home Built Before 1980
Clay, cast iron, and older pipes deteriorate after 40+ years.
Large Trees Nearby
Maples, willows, and poplars commonly damage older sewer lines.
Start planning a replacement when
Wet Spots in Yard
Soggy areas near the water line path indicate leaks
Discolored or Rusty Water
Indicates corroded pipes. This is common in pre-1970 homes as they age.
Low Pressure
Low water pressure throughout your home or business suggests leaks or severe corrosion
High Water Bills
Unexplained increases suggest underground leaks.
Galvanized Pipes
If your home has original galvanized lines that are 40+ years old, they’re likely corroding.
Common Trenchless Sewer and Water Line Repair Questions
Still have questions? Reach out anytime—our team is here to help with all your plumbing needs.
-
Cost depends on many factors, including pipe size, distance, and terrain. While 10-30% higher upfront than traditional excavation, you avoid thousands in restoration costs.
-
1-3 days for most projects. Traditional excavation takes 5-7 days plus restoration time.
It generally takes 1-3 days (prep, execute, wrap up). Traditional methods can take 1-5 days, not counting any landscape, yard, or pavement restoration.
-
It works for 85-90% of replacements, including challenging terrain in Snoqualmie Ridge, Issaquah Highlands, and Fall City. A camera inspection determines if your pipe is a good candidate.
-
A long time. The conduit we use carries a lifetime warranty. CIPP (cured-in-place pipe) lining carries a widely accepted 50-year design life, a standard recognized across the engineering industry and supported by EPA retrospective evaluations and peer-reviewed research published in Frontiers in Water. Real-world liner samples tested after 20-plus years in service showed no signs of degradation that would prevent them from reaching their full intended lifespan. Locally, municipalities across Washington have been deploying CIPP in their aging sewer infrastructure. Mercer Island's Basin 40 sewer rehabilitation project is one example, targeting lines originally installed in the 1950s and '60s. Pipe bursting replaces the old line with HDPE pipe, which carries a comparable 50 to 100-year lifespan per the Plastics Pipe Institute. Either way, you're not patching the problem. You're resolving it for decades.
A few things affect longevity: installation quality (hire certified crews), what runs through the pipe, and local soil conditions. For the average residential homeowner, 50 years is a reasonable and well-supported expectation.
