Heat Pump Installation in Snoqualmie, Issaquah & the Eastside
One system for heating and cooling, sized right for your home. We handle the load calculation, the installation, the permits, and the PSE rebate paperwork.
Why heat pumps fit East King County homes
Our winters are mild, our summers are getting hotter, and our electricity is among the cleanest and least expensive in the country. That combination is what a heat pump is built for. A modern cold-climate heat pump heats efficiently well below freezing and cools in July without a separate air conditioner, which is why Washington's energy code and PSE's rebate programs both steer homeowners toward them.
Noble installs ducted heat pumps that replace a furnace and use your existing ductwork, and ductless mini splits for homes without ducts. Our HVAC lead has 22 years in the mechanical trades and holds refrigeration, electrical, and gas licenses, so the same crew handles the refrigerant lines, the electrical circuit, and the gas furnace if you're keeping one as backup.
Heat pump services
Heat Pump Installation
Ducted systems that work with your existing ducts, sized with a Manual J load calculation and matched to your home's insulation and layout. Equipment selection, permits, electrical, and rebate paperwork included.
Furnace-to-Heat-Pump Conversion
Replace an aging gas or electric furnace with a heat pump and air handler, or keep a sound furnace as backup in a dual-fuel setup. We'll show you the operating cost of each before you decide.
Heat Pump Repair
Weak heat, ice that won't clear, constant auxiliary heat, refrigerant leaks, reversing valve and defrost problems, failed compressors and control boards. All major brands.
Heat Pump Maintenance
Annual service keeps the charge correct, the coils clean, and the warranty valid.
Heat pump only, or heat pump plus furnace?
Both are good answers. Which one fits depends on the house.
Dual-fuel (heat pump plus gas furnace) makes sense when
Your furnace is newer and in good shape
The home is large, older, or drafty and loses heat quickly
You want gas backup for cold snaps and power-restoration days
You want the lowest operating cost in the coldest weeks of the year
All-electric heat pump makes sense when
Your ductwork is in good shape and reasonably sealed
The home is insulated to something like modern standards
You want air conditioning and don't have it
You'd like to stop paying a gas bill or don't have gas service
You want the largest available rebates
Cold-climate models hold their capacity well below freezing, with electric backup for the handful of nights that go lower.
FROM THE FIELD
Ducted heat pump installation in a Sammamish home
The Problem
The house had an electric furnace that was doing exactly what electric furnaces do: heating the home reliably and expensively. The winter bills had become the biggest line on the budget, and there was no air conditioning at all, which the last few summers had made hard to ignore. The homeowners had read about heat pumps and the PSE rebates, but they’d also heard that heat pumps “don’t work in the cold,” and they weren’t sure their house was a fit.
They called us with two questions: would a heat pump keep the house warm in January, and what would it cost to run compared to what they had?
What We Did
We started with a load calculation and a ductwork test. The ducts were sound, which meant a ducted heat pump could use them as they were. We sized a cold-climate heat pump to the home’s actual heat loss rather than to the old furnace’s rating, which turned out to be oversized. The outdoor unit went on a level pad clear of the siding, with a dedicated circuit and a disconnect within sight of the unit. Inside, a new air handler with electric backup strips replaced the old furnace and tied into the existing ductwork. We ran and insulated the line set, sealed the penetrations, routed the condensate where it can’t freeze, weighed in the refrigerant charge, verified airflow, set the balance point so the backup heat only runs when it has to, and walked the homeowners through the thermostat. Permit pulled, inspection passed, rebate paperwork submitted on their behalf.
The Result
Heating and cooling from one system, using the ductwork they already had
Rated to heat efficiently well below freezing, with backup heat for the rare night that needs it
PSE rebate-eligible equipment, paperwork handled by Noble
Installed in one day, permitted and inspected

What a proper heat pump install looks like
Sized to the house, not the old furnace.
Oversizing is the most common heat pump mistake. An oversized unit short-cycles, never runs long enough to dehumidify in summer, and wears out early. We run a Manual J load calculation on every install.
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.
The details you can see.
A level pad, a disconnect within sight of the unit, a line set that's insulated and protected, penetrations sealed, condensate drained where it can't freeze or stain. These are the things that separate a ten-year install from a twenty-year one.
Signs your heat pump needs attention
Call for service if you notice
Ice That Won’t Clear
Frost is normal; a unit still iced over after a defrost cycle isn't.
Aux Heat Always On
The backup heat indicator stays lit, and the bill shows it.
Weak Heat, Constant Running
The system never shuts off, but the air is barely warm.
New Outdoor Noises
Grinding, rattling, or a compressor that struggles to start.
Water Around the Indoor Unit
A clogged condensate line, or a frozen coil thawing.
Start planning a replacement when
It’s 12 to 15 Years Old
Compressors and coils wear out; efficiency drops well before they fail.
It Uses R-22
The refrigerant is no longer produced, so every recharge costs more.
Compressor Failure
On an older unit, the most expensive repair rarely makes sense.
Repairs Every Season
Annual service calls add up to a down payment on a new system.
The Furnace Is Due Anyway
Doing both at once gets you a matched, rebate-eligible system.
Heat pump questions we hear most
Still have questions? Reach out anytime—our team is here to help with all your plumbing needs.
-
Yes. Cold-climate heat pumps are rated to keep heating well below freezing, and valley winters rarely go below the low 20s. For the few nights that do, the system has backup heat, either electric strips or your gas furnace in a dual-fuel setup.
-
It depends on the size of the home, whether ductwork needs work, and the equipment tier. We quote every job in writing after a site visit, with rebates applied so you see the real number.
-
Puget Sound Energy offers rebates on qualifying heat pumps and ductless systems, and state or utility incentives change from year to year. We'll tell you exactly what your options qualify for when we quote the job, and we handle the paperwork.
-
Yes. A dual-fuel system uses the heat pump for most of the season and the furnace for the coldest nights. If your furnace is newer, it's often the most cost-effective path.
-
One to two days for most homes. Jobs that need duct repairs or an electrical panel upgrade take longer, and we'll tell you that in the estimate.
-
Usually not, but we test it. Leaky or undersized ducts are the most common reason a new heat pump underperforms, so we check static pressure before we quote and fix what matters
-
About 15 years with annual maintenance. We install recommended brands and service all major brands.
