Furnace Repair in South Kennewick, WA
In a part of the city with a large fifty-year-old housing cohort, furnace age spans a wide range — and so does what a service visit actually needs to cover.
Young’s Heating and Cooling inspects combustion and the heat exchanger as standard on every furnace visit. On a recent unit that is diligence. On an older one it is the most important thing we do.
Call (509) 525-4328 or schedule online.
If a carbon monoxide detector has sounded, get everyone outside first, then call (509) 525-4328 from outside. For a standard no-heat call we prioritize those too, especially in a hard freeze.

Two Waves of Housing
The City’s plat records show 277 plats across South Kennewick, arriving in two distinct waves: 44 in the 1970s and 131 across the 1990s and 2000s. Kennewick’s population more than doubled during that first decade.
For heating equipment this means a genuinely split picture. Homes from the earlier wave are on their second or third furnace; homes from the later wave may still be on their first.
Why the Heat Exchanger Gets Checked Every Time
The heat exchanger separates combustion gases from the air circulating through your house. It degrades with age and repeated thermal cycling, and a crack in it is the mechanism by which a furnace can put carbon monoxide into living space.
In a 1970s home the furnace is unlikely to be original, but it may well be the second or third unit and itself decades old. That is exactly the situation where an inspection matters rather than just getting it running again.
Every home with a gas appliance needs working carbon monoxide detectors on every level. If one sounds, get everyone out of the house first and call from outside. Do not go back in to investigate.
What We Repair
- No heat – Pilot and thermocouple faults on older units, igniters and flame sensors on newer ones.
- Dirty or failing flame sensors – Lights, runs briefly, shuts off. Often just needs cleaning.
- Blower and motor faults – Worn bearings, seized motors, insufficient airflow.
- Short cycling – Frequently an oversized furnace, especially where a 1970s home was upgraded without a load calculation.
- Pressure switch and condensate faults – On the newer condensing units.
- Heat exchanger inspection – Every visit, every furnace.
- Venting and flue problems – More common in older installations, and both an efficiency and a safety issue.
- Gas valve and control faults – Diagnosed before anything gets replaced.
The Sizing Trap in Older Homes
Worth knowing before you replace anything. If a 1970s house has had insulation, windows or air sealing improved since it was built — and many have — it needs less heating capacity than it originally did. Replacing the old furnace with an identically-rated new one then installs something oversized.
An oversized furnace heats the space quickly, shuts off, cools, and restarts. It short-cycles, wears components faster, and heats less evenly than a correctly sized unit would. We size by load calculation rather than by matching the plate on the old furnace.
Repair or Replace?
| Situation | What we’d typically recommend |
|---|---|
| Newer furnace, sensor or igniter | Repair. Routine and inexpensive. |
| Older furnace, single cheap component | Repair. Buys seasons at modest cost. |
| Older furnace, expensive component | Price both honestly. |
| Cracked heat exchanger, any age | Replace. Safety decision, not economic. |
| Replacement in an upgraded 1970s home | Re-size by load calculation, don’t match the old unit. |
Where replacement is right we cover heating replacement, oil-to-gas conversion where relevant, and financing.

Frequently Asked Questions
How do I know if my heat exchanger is cracked?
You generally can’t see it from outside, which is why it’s inspected during service. Signs warranting a same-day call: a CO detector alarm, soot around the furnace, a persistent acrid smell, or a yellow flickering burner flame rather than steady blue.
My furnace short-cycles constantly. What causes that?
In an upgraded older home it’s frequently an oversized furnace — a replacement matched to the previous unit’s rating rather than to the house’s actual heat loss after insulation or window improvements. It can also be a dirty flame sensor or restricted airflow. Worth diagnosing properly.
Should I replace my old furnace with the same size?
Not automatically, and this matters in 1970s homes specifically. If the house has been improved since it was built, it needs less capacity than it once did. Matching the old rating installs something too large, which short-cycles and heats unevenly.
Is an old furnace dangerous?
Not inherently — many run safely for years. What matters is annual inspection, correct combustion and venting, a sound heat exchanger, and working CO detectors. Age combined with no inspection is the combination to avoid.
Why does my 1970s house heat unevenly?
Usually the ductwork rather than the furnace. Fifty-year-old duct networks develop leaks and crushed runs, and return air is frequently insufficient. Worth assessing before assuming the furnace is at fault.
Do you offer maintenance plans?
Yes — seasonal tune-ups, priority scheduling and repair discounts. On older equipment the annual heat exchanger check alone justifies it.
