No hedging. Each page says which one we would put in, and when we would not.
Air-source heat pump vs. Natural gas furnace
Heat pump vs. gas furnace: which one belongs in a Bellingham house?
If your gas furnace still works, the honest answer in Bellingham is usually to keep it and add cooling, or go hybrid. Cascade is the gas utility here, so PSE…
Read the verdict →Ductless heat pump vs. Electric baseboard and wall heaters
Heat pump vs. electric baseboard: the one Bellingham upgrade PSE pays for
The heat pump wins, and it is not close. Baseboard converts a dollar of electricity into a dollar of heat; a variable-speed heat pump moves several times that…
Read the verdict →Ductless mini split vs. Central ducted heat pump
Ductless mini split vs. central heat pump: which one fits your house?
Let the ductwork decide. If the house already has sound, sealed ducts in conditioned space, a ducted heat pump gives you even temperatures and no wall units. If…
Read the verdict →Ductless mini split vs. Window air conditioner
Mini split vs. window air conditioner: what a Bellingham summer actually needs
A window unit is the honest choice for one hot bedroom, a rental you cannot modify, or a summer you need fixed this week. A mini split is the right call if you…
Read the verdict →Ductless heat pump vs. Wood stove
Heat pump vs. wood stove: what works in the foothills, and what does not
Keep the stove, add the heat pump. The heat pump should carry your season because it is cheaper, cleaner and automatic; the stove earns its keep during outages…
Read the verdict →Air-source heat pump vs. Propane furnace
Heat pump vs. propane furnace: the foothills and north-county question
The heat pump wins on running cost almost every year, because propane is delivered fuel at delivered-fuel prices. Keep the propane furnace as the backup stage…
Read the verdict →Air-source heat pump vs. Oil furnace
Heat pump vs. oil furnace: what to do with an aging oil system
Convert. Oil is delivered fuel with a tank liability attached, and a heat pump beats it on running cost, cooling and safety. The honest caveat is that PSE pays…
Read the verdict →Single-zone system vs. Multi-zone system
Single-zone vs. multi-zone mini split: how many outdoor units do you want?
For two or three rooms, separate single-zone systems usually beat one multi-zone: better part-load efficiency, independent failure, simpler diagnostics…
Read the verdict →Cold-climate rated heat pump vs. Standard-efficiency heat pump
Cold-climate vs. standard heat pump: is the premium worth it at 19°F?
It depends on your address and your backup. In Bellingham at 19°F, a good standard variable-speed unit with correctly sized backup heat is often enough. In…
Read the verdict →Heat pump water heater vs. Tankless water heater
Heat pump water heater vs. tankless: which one belongs in your utility room?
In Bellingham the heat pump water heater usually wins, because PSE pays $1,000 for a qualifying NEEA Tier 3 or 4 unit and pays nothing toward tankless. Choose…
Read the verdict →Heat pump water heater vs. Standard electric resistance tank
Heat pump water heater vs. standard electric tank: the easiest upgrade in the house
Go heat pump if the space allows it. Up to 70% less electricity per PSE, 13 to 15 years of life against 8 to 10, and a $1,000 rebate that no standard tank…
Read the verdict →Gas tankless water heater vs. Electric tankless water heater
Gas tankless vs. electric tankless: which one your house can actually support
For whole-home hot water, gas tankless is usually the only one your service can support: electric tankless draws enormous current and most older Bellingham…
Read the verdict →Reverse osmosis system vs. Carbon filter
Reverse osmosis vs. carbon filter: which one your water actually needs
They solve different problems, so match the technology to your test results. Carbon handles chlorine, taste and odour, which is what most Bellingham city-water…
Read the verdict →Whole-home filtration vs. Under-sink reverse osmosis
Whole-home filtration vs. under-sink RO: treat the house or treat the tap?
They are not competitors, they are a sequence. Whole-home filtration protects plumbing, fixtures and appliances from sediment, iron and manganese; under-sink…
Read the verdict →Repair the existing system vs. Replace the system
Repair or replace an old heat pump: how to decide without guessing
Repair a unit under about 12 years old when the failure is a part — a board, a fan motor, a contactor, a sensor. Replace when the compressor fails, when the…
Read the verdict →What changes the answer in Bellingham
Bellingham's outdoor heating design temperature is 19°F, colder than Sea-Tac's 24°F, and the city is in climate zone 4C (marine) — heating-dominated and damp, with very few hours below 10°F. That combination changes the answer on almost every one of these decisions.
