New Subdivisions, New Heat Pumps, and the Setup Problems That Come with Them
Subdivisions along Littlerock Road, around Bush Prairie and on the south side of town keep adding homes, and many of them arrive with a heat pump already installed. That’s a good start. Problems we see in young systems include a refrigerant charge that was never verified, thermostats left on factory settings that call heat strips too often, and condensate lines without enough slope.
Older parts of Tumwater, including Tumwater Hill and the blocks off Capitol Boulevard, tell a different story: mid-century and 1970s–80s homes with gas furnaces or electric forced air, and ductwork that has seen decades of damp crawl-space air.
- Unverified refrigerant charge on new installs
- Heat strips running more than they should
- Poorly sloped or clogged condensate lines

A Tumwater HVAC Contractor’s First-Year Checkup, Near the Falls and the Old Brewery
Getting around town, we pass Tumwater Falls Park and the old Olympia Brewery buildings on the Deschutes, the historic Crosby House, and the airport off Capitol Boulevard. Newer neighborhoods spread out from there toward Littlerock Road.
Here’s a typical visit to a new Tumwater home: the owners notice a high winter electric bill in year one. We find the thermostat staging heat strips at the first sign of cold and a charge that’s a bit off. We correct the charge, reset staging so the heat pump carries the load, clean the condensate line, and show the owners how to read their thermostat. The bill drops, and nothing had to be replaced.

What Tumwater homeowners get when they book us
Tumwater splits between brand-new subdivisions and mid-century homes on Tumwater Hill. Our practices cover both halves of town.
Startup numbers you can keep
On a young heat pump we measure charge, airflow and temperature split, then give you the readings. That record helps if a builder-warranty question comes up later, and it sets a baseline for every annual visit.
Heat-strip staging checked against the bill
PSE supplies both electricity and gas in Thurston County, so first-winter bills tell a clear story. We compare them with thermostat staging and adjust lockout temperatures so the strips stop doing the heat pump’s job.
Old crawl-space ducts inspected first
Homes off Capitol Boulevard have ducts that sat in damp crawl-space air for decades. We photograph and test them before recommending furnace replacement or a heat pump, and if duct cleaning won’t help, we tell you.
Gas changes done by the same crew
When an older Tumwater furnace swap or a dual-fuel coil needs gas line changes, our crew makes them and pressure-tests the piping along with the heating work, so no second contractor is needed.
Builder warranty first: who should fix a young Tumwater heat pump
If your Tumwater home is only a year or two old, call the builder or the original installer first about anything that looks like a defect. New-construction systems usually carry an installer labor warranty and a manufacturer parts warranty, and an outside contractor opening the system for a warrantable defect can complicate a claim.
Where we fit is the gray zone: thermostat staging, a charge nobody verified, a condensate line with poor slope. A builder may not treat those as defects. Before any visit, gather:
- Model and serial numbers from the outdoor unit and the air handler
- Proof the equipment was registered with the manufacturer, since registration often affects parts coverage
- The builder’s warranty paperwork and the installing contractor’s name
- First-winter utility bills, which show when heat strips were doing the work
Sorting out who owns the problem
With those in hand, it’s much easier to tell whether a problem belongs to the builder, the manufacturer or a scheduled service visit. Our heat pump maintenance guide covers what owners can handle between visits.
FAQ
HVAC questions from Tumwater homeowners
My new Tumwater home has a heat pump. Does it need maintenance already?
Yes. A first-year checkup is one of the best investments for a new system. It confirms the refrigerant charge, airflow and thermostat staging were set correctly at install, and catches condensate issues early. After that, an annual visit keeps coils clean and defrost working properly through wet Thurston County winters.
Why do my heat strips run so often on a new heat pump?
Usually because of thermostat settings, not a failed heat pump. Many thermostats ship with aggressive auxiliary heat staging that brings on the strips whenever the temperature lags. A low refrigerant charge can also force strips to work harder. Adjusting staging and verifying the charge often fixes it without any parts.
Do I need a permit to add a mini-split to a Tumwater ADU or garage?
Usually, yes. Inside city limits, a new mini-split generally needs a mechanical permit from the City of Tumwater, and the new circuit for the outdoor unit typically needs its own electrical permit. An ADU may also have been approved with specific heating requirements, so check its original permit. Your installer should pull the permits and schedule inspections as part of the quote.
Should I keep gas or switch to a heat pump in an older Tumwater home?
It depends on the furnace’s condition, the ducts and your electrical panel. Because PSE supplies both gas and electricity in Tumwater, you can compare rates from one utility. A furnace in good shape often pairs well with a heat pump as dual fuel. A worn furnace plus sound ducts can justify a full heat pump. We test the furnace and ducts, then price the options side by side.
