Heating and cooling is the trade where the most expensive decision — replace or repair — gets made under the most pressure, usually on the coldest morning of the year with the house already cold.
Sensors, igniters, capacitors and thermostats are worth repairing at almost any age. A cracked heat exchanger or failed compressor on a system in its late teens means putting significant money into equipment that is nearly finished. Ask for the specific failed component in writing before deciding either way.
Heating equipment sits idle from March to November and then gets asked for everything at once. The parts that give out in that first week are cheap and predictable across the state — a flame sensor coated after a season of dust, an igniter at the end of its life, a pressure switch tripping on a blocked flue. What makes it expensive is timing, because when everyone calls the same morning the schedule fills before lunch.
Heat pumps suit most of Oregon well and their case has strengthened as summers have got hotter — one system that heats and cools is usually cheaper than a furnace plus separate air conditioning. The caveat is genuinely cold stretches, where efficiency falls. A heat pump with an existing furnace retained as backup handles that, and is generally cheaper than replacing a furnace that still works.
An oversized system short-cycles: it reaches temperature fast, shuts off, and never runs long enough to distribute air evenly or remove humidity. It also wears faster. Oversizing is common because it is the safe error for an installer to make. Ask whether a load calculation was performed for your house specifically — its insulation, windows, orientation — rather than estimated from square footage.
Ducting run through unconditioned crawlspaces and attics with degraded insulation loses conditioned air before it reaches the room. The symptom is a system that runs constantly while rooms never reach temperature, and it is routinely misdiagnosed as an equipment problem. Sealing and insulating ducts is unglamorous and frequently produces a bigger comfort improvement than new equipment would.
Utility and state incentives for heat pumps and weatherisation in Oregon can materially change the comparison between repairing and replacing. Programmes and amounts change, so confirm current offers with your own utility rather than relying on a contractor's summary — and ask which programmes they are set up to process, because that varies.
Describe the project once and we match it with vetted local pros who actually do this work — you choose who to hire, or nobody at all.
Furnace and heat pump replacement generally requires a permit and inspection covering gas connection, venting, electrical and condensate. Your contractor should pull it under their own CCB licence. Unpermitted HVAC work is exactly the detail an insurer examines after a fire or a carbon monoxide incident.
HVAC work for compensation requires an Oregon Construction Contractors Board licence. The registry is free and public — confirm the status is active, that bond and insurance carry future expiry dates, and read any complaint history. Two minutes, and it removes a category of risk entirely.
Switching from gas heat to a heat pump adds substantial electrical load, and in homes already running an EV charger or induction range the existing panel is frequently the constraint. Get the load assessed during quoting. A service upgrade is a known cost when planned and an unwelcome one when discovered on installation day.
| System | Up-front cost | Running cost | Best suited to |
|---|---|---|---|
| Gas furnace | Moderate | Varies with gas price | Homes with existing gas, cold sites |
| Heat pump | Higher | Low, heats and cools | Most of the state, mild winters |
| Heat pump + furnace backup | Highest | Lowest overall | Cold snaps, existing furnace still good |
| Ductless mini-split | Moderate | Low | Homes without ducts, additions |
Repairs are priced by part and labour, and the common seasonal failures are among the cheapest in the trade. Replacement is driven by system type, correct sizing, whether ductwork needs repair, and whether you are changing fuel. Moving from gas to a heat pump can carry electrical work that is a substantial line on its own. Ask every replacement quote three things: whether a load calculation was done for your house specifically, what the ductwork assessment found, and what the labour warranty covers separately from the manufacturer's parts warranty. Those three answers explain most of the gap between two bids.
Search the Construction Contractors Board registry by business name or licence number. Confirm the status reads active and that bond and insurance have future expiry dates. One resolved complaint over a long history is normal; a repeating pattern is not.
Commonly fifteen to twenty years for a furnace and slightly less for a heat pump, though maintenance and correct sizing move that range considerably. A system that was oversized at installation wears faster than a correctly sized one regardless of brand.
Very much so for homes without existing ducts, for additions, and for rooms that were never comfortable. It avoids the duct losses that undermine central systems, and it lets you condition only the spaces you use. The trade-off is visible indoor units and per-zone cost.
Generally yes, and your contractor should pull it. The inspection covers gas, venting, electrical and condensate. It is routine, inexpensive relative to the job, and it is the documentation that matters if there is ever an insurance question.
Annually, before the heating season rather than during it. Most failures that become an emergency call in December are visible in October to anyone who looks — and October is ordinary-rate work with parts readily available.
Most often duct losses or degraded insulation rather than the equipment. It can also be an undersized system or a failing component. Have the ducts assessed before agreeing to replace equipment — otherwise you may buy a new system that reproduces the same complaint.
Nothing. Describing the project and receiving quotes is free, and there is no fee if you hire someone. You pay your contractor for the work, and that is the entire arrangement.
Usually two to four, matched on trade, project size and whether they genuinely work your area. Only those matched to your job see your details — we do not resell requests.
