What’s the difference between a gas and electric furnace?
An electric furnace installed in your Tacoma home or business can be less expensive to install than a gas furnace, but gas is more energy efficient. This means that you can expect to pay less on a monthly basis to heat your home. If natural gas is not available for your home, an electric furnace is usually a simple installation and furnace replacement in can last up to 30 years in your Tacoma Home or Office.

When is a ductless heat pump the right choice?
A ductless heat pump installed in your Tacoma home or business is a natural choice when there is not an existing duct system designed to provide heating and cooling. A ductless heat pump can be installed in almost any home often at a lower cost than installing a new duct system, furnace, and air conditioner.

When replacement is the right call
Professional Furnace Replacement for Tacoma Homes
Homeowners reach a furnace replacement in Tacoma one of three ways: a failed heat exchanger that condemns the unit, a repair that has become hard to justify on equipment past fifteen years, or a remodel that changed what the house actually needs. Each route ends at the same question, which is what to put in and how big it should be.
That question is answered by the building, not the old equipment. Tacoma’s housing stock runs from 1920s bungalows in the North End to 1990s builds in South Tacoma, and the original furnaces were frequently oversized by a wide margin. Replacing a 100,000 BTU unit with another of the same capacity perpetuates short cycling, uneven temperatures, and noise that no efficiency rating will fix, so every furnace replacement in Tacoma we quote starts from the calculated load and the condition of the ducts, venting, gas supply, and condensate path.
Compare the equipment
Furnace Replacement Options for Your Tacoma Home
Efficiency tier, staging, and whether you stay on gas at all are separate decisions. Each has a different installed cost and a different effect on comfort.
Standard-Efficiency Gas Furnace
An 80% AFUE furnace remains the lowest installed cost and can reuse existing metal or chimney venting in many Tacoma homes. It is often the right answer when the home is on gas, the ducts are sound, and the budget is the binding constraint.
High-Efficiency Condensing Furnace
A 95% AFUE or higher unit cuts fuel use meaningfully but requires dedicated PVC venting through a sidewall and a condensate drain. The venting route and drain path have to be confirmed on site, not assumed.
Two-Stage and Modulating
Staged or modulating burners paired with a variable-speed blower run longer at lower output, which evens out temperatures and cuts noise. The gain is largest in homes that currently short cycle from an oversized single-stage unit.
Heat Pump or Dual-Fuel Alternative
Given Tacoma Public Utilities and PSE incentives, a heat pump or a heat pump paired with a gas furnace is frequently competitive on total cost while adding cooling. We price it alongside the furnace rather than after you have signed.
Repair or replace
Signs Your Tacoma Furnace Should Be Replaced
- A combustion test or inspection has found a cracked heat exchanger.
- The furnace is past fifteen years and needs a major repair.
- A single repair approaches a third of replacement cost.
- The blower, control board, or gas valve has already been replaced once.
- Some rooms never reach temperature while others overheat.
- The furnace short cycles or runs noticeably louder than it used to.
- Heating costs have climbed without a rate change.
- Parts are on extended order or no longer supported.
- Carbon monoxide has been detected anywhere in the home.
A cracked heat exchanger or a carbon monoxide reading is not a repair decision. The unit should be shut down and red-tagged, temporary heat provided, and replacement quoted the same day.
A combustion analysis and heat exchanger inspection are what justify a replacement recommendation.
How the project runs
What a Professional Furnace Replacement Includes
01
Assess the Home
Inspect the existing furnace, ductwork, returns, venting, gas supply, electrical capacity, and condensate options before discussing equipment.
02
Calculate the Load
Run a Manual J load calculation using insulation, windows, air leakage, layout, and orientation rather than square footage or the old capacity.
03
Compare the Options
Present efficiency tiers, staging, and the heat pump or dual-fuel alternative with installed cost, rebates, and expected comfort difference side by side.
04
Define the Scope
Issue a written proposal covering equipment, duct and venting work, gas and electrical, permit, removal, and any assumption that still needs confirming.
05
Permit and Install
Pull the City of Tacoma permit, remove and recycle the old unit, set and connect the new furnace, and correct duct, venting, and drainage as scoped.
06
Commission and Verify
Set gas pressure, measure temperature rise and static pressure, run a combustion analysis, meet the inspector, and walk you through operation and filter changes.

Understand the proposal
Furnace Replacement Terms Explained
AFUE
Annual fuel utilisation efficiency, the share of fuel converted to usable heat. 80% is standard efficiency; 90% and above is condensing and needs different venting.
Manual J
The industry load calculation method. It determines the capacity the house actually needs, which is frequently well below the unit being replaced.
Heat Exchanger
The component separating combustion gases from the air you breathe. A crack condemns the furnace; there is no repair that restores it.
Temperature Rise
The difference between return and supply air. The installed system must operate inside the nameplate range, which depends on correct airflow.
Static Pressure
The resistance the blower works against. High static from undersized ducts or returns shortens the life of new equipment as surely as it did the old.
Condensate Drain
High-efficiency furnaces produce acidic condensate that must reach an approved drain with correct fall, or a pump where gravity will not serve.
Tacoma project details
Local Conditions That Belong in the Project Plan
A furnace replacement in Tacoma is shaped less by the furnace than by what surrounds it. Older homes frequently need duct and return corrections, chimney-vented equipment cannot simply be swapped for condensing equipment, and the permit path runs through the City of Tacoma.
- Pull the City of Tacoma mechanical permit and schedule the inspection before the crew is committed.
- Assess crawlspace and basement ducts for leakage, crushing, and damaged insulation before sizing.
- Check return air capacity, which is undersized in a large share of pre-1970 Tacoma homes.
- Plan venting carefully when moving from a chimney-vented furnace to a condensing unit.
- Confirm gas line capacity and shutoff location, particularly on multi-appliance runs.
- Route condensate to an approved drain with correct fall, and add a pump where gravity will not serve.
- Check Tacoma Public Utilities and Puget Sound Energy rebates, which favour heat pump conversions.
- Verify combustion air and clearances in tight utility rooms and converted closets.
Why homeowners choose us
Why Choose Home Comfort Alliance
Locally owned since 1977, dispatched to Pierce County from our Sumner branch, and holding HVAC, plumbing, and electrical licences under one Washington contractor registration. On a furnace replacement that needs a new circuit, a condensate pump, or a gas line correction, the whole job stays with one crew.
Sized to the Building
A Manual J load calculation rather than nameplate matching. Oversizing is the most common defect in residential furnace replacement and it is entirely avoidable.
NATE-Certified Technicians
North American Technician Excellence certification, ACCA membership, and BBB accreditation. On a replacement, certification shows up in the commissioning numbers.
Registered Utility Trade Ally
A registered contractor with Tacoma Public Utilities and Puget Sound Energy. Rebate eligibility is confirmed and the paperwork filed by the team doing the installation.
One Team for All Three Trades
HVAC, plumbing, and electrical under one license. A new circuit, a condensate pump, or a gas line correction does not become a second contractor and a second visit.

What Tacoma Homeowners Say
Furnace replacement questions
Frequently Asked Questions
How much does furnace replacement cost in Tacoma?
The largest variables are the calculated capacity, efficiency tier, staging, and what the ducts, venting, gas line, and electrical require. Because a condensing furnace needs new venting and a condensate drain, two homes on the same street can differ substantially. Every proposal carries a fixed price after an on-site evaluation.
Should I repair or replace my furnace?
Past fifteen years, with a repair approaching a third of replacement cost, replacement usually wins on total cost of ownership. A cracked heat exchanger removes the choice. We price both paths on the same visit so the comparison is explicit rather than implied.
How long does a furnace replacement take?
A straightforward like-for-like swap is generally a single day. Converting a chimney-vented furnace to a condensing unit, correcting return air, or upsizing a gas line can extend it into a second day. The proposal sets out the expected sequence.
Do I need a permit to replace a furnace in Tacoma?
Yes. Furnace replacements require a mechanical permit through the City of Tacoma and are inspected. We pull the permit, meet the inspector, and leave the signed documentation with you so it does not surface at resale.
Should I switch to a heat pump instead?
It is worth pricing. The Puget Sound climate suits heat pumps well, they add cooling, and Tacoma Public Utilities and PSE incentives are meaningful. A dual-fuel system keeping the new furnace as backup is also an option. We quote the alternatives alongside the furnace.
Will a bigger furnace heat my home better?
Usually the opposite. An oversized furnace satisfies the thermostat quickly, short cycles, and leaves rooms furthest from the air handler cold while wearing out the igniter and inducer faster. Correct sizing comes from the load calculation.
Do my ducts need work at the same time?
Often, in older Tacoma homes. Leaking, crushed, or undersized ducts and inadequate return air will limit a new furnace exactly as they limited the old one. We measure static pressure and quote any corrections as a separate, visible line.
What warranty comes with a new furnace?
Manufacturers typically provide ten years on parts with registration, and heat exchanger coverage is usually longer. Labour coverage is stated separately in the proposal. Many warranties require documented annual maintenance to stay valid.
Can you install a furnace in winter?
Yes, and most replacements happen in heating season. If your furnace has been red-tagged or has failed outright, we supply temporary heat while the equipment and permit are arranged.
