Repair Or Replace? The Arithmetic, Not The Sales Pitch
Age, which component failed, and what else is close behind it. Three numbers that settle it — and a rule of thumb for when the repair is throwing money at a lost cause.
Load calculated, ducts measured and sealed, charge set to spec and every register balanced. A system that is quiet, even, and cheaper to run than the one it replaced.
Heat pumps, furnaces, ductless and ductwork, set up properly and measured before we call it finished.

No heat in January, no cooling in August. Diagnosed properly and repaired the same visit wherever the part allows.

The visit that stops the January call. Filters, coils, refrigerant, safeties and a written note of anything starting to wear.

If it can be fixed economically, that is the quote you get. A replacement number only comes out when repair genuinely does not make sense, and we will show you the arithmetic.
For a replacement, we measure the house — insulation, windows, ducts, orientation — instead of copying the old unit's label. Oversized systems short-cycle, run humid and wear out early.
Charged to spec, airflow measured, ducts sealed and every register balanced. An install that is not commissioned is only half done.
Temperature split, static pressure, and the settings we left it on — written down, so the next person has a baseline.

Drag the slider. A crooked unit on a cracked pad with bare sagging lines, replaced with a level install, an insulated line-set and a system matched to the house.
"Another company had already quoted me eleven thousand for a full replacement. These people found a failed capacitor, replaced it for under two hundred, and told me the system had a good five years left. They have my business for those five years."
"First hot week of the year, everybody booked solid, and they still got someone out the same afternoon. Fixed it in an hour and did not charge a premium for the day."
"They actually measured the house before quoting a heat pump instead of matching the old unit. The back bedroom has been the same temperature as the rest of the house for the first time in nine years."

Most of our work is in east Multnomah County and the neighborhoods around it. Two weeks a year everybody calls at once — the first hard frost and the first real heat — so if you already know your system is on its last season, booking outside those weeks gets you a better job and a shorter wait.
No. We quote the repair first, and only put a replacement number next to it when the repair genuinely does not make sense — and then we show you the arithmetic rather than asking you to take it on faith. Plenty of our visits end with a part and a bill under a few hundred dollars.
Roughly: under ten years old and a single failed component, repair. Over fifteen with a major failure — compressor, heat exchanger — replace. In between it depends on the specific part, the refrigerant it uses and what else is close to going. We will tell you which of those you have.
For most homes in this climate, yes — mild winters are exactly the conditions they are efficient in, and they cool in summer too, which increasingly matters. There are houses where it is the wrong call, usually because of ductwork or electrical capacity, and we will say so rather than sell you one anyway.
Almost always ductwork rather than the system — a run that is too long, too small, leaking into a crawlspace, or a register nobody has balanced since the house was built. It is usually fixable without touching the furnace, and it is the cheapest comfort improvement most houses can make.
That is a load calculation, and it is the part most often skipped. It accounts for square footage, insulation, windows, orientation and your actual ductwork. Sizing off the old unit copies whatever mistake was made last time — and oversized is worse than undersized, because it short-cycles, never dehumidifies and wears out early.
Once a year for a furnace or heat pump, twice if you run cooling hard. The honest reason is not the tune-up itself — it is that somebody looks at the safeties and the wear parts before January decides for you.

Repair Or Replace
Age, which component failed, and what else is close behind it. Three numbers that settle it — and a rule of thumb for when the repair is throwing money at a lost cause.
Sizing
Bigger is not better. An oversized unit reaches temperature fast, shuts off, never dehumidifies, and wears out its own compressor doing it.
Ductwork & Airflow
Before you replace a system that works, check the run feeding the room that doesn't. Leaks, undersized branches and unbalanced registers account for most comfort complaints.
Bring us the house with the room that has never been right. We will measure the ducts and the load rather than quoting from the doorway, and tell you what would actually fix it.
