HVAC answers, built for the Pacific Northwest
Marine winters, warming summers, tight modern homes, smoke season, and a rebate landscape all its own — our guides answer the questions this region actually raises, honestly.
Every guide here is written and reviewed by the Home Energy Group team — family-owned, celebrating 25 years serving SW Washington and the Portland metro, licensed in Washington (WA LIC# HOMEEGI003J7) and Oregon (OR CCB# 184255) — and cites real sources from ENERGY STAR, the EPA, ACCA, and the region's actual utility programs. Answer first, sales pitch never.
Heat Pumps & Ductless
Why the mild marine PNW is heat pump country — and what conversions really involve.
Why heat pumps are a perfect match for the Pacific Northwest
Southwest Washington and the Portland metro sit in a mild marine climate where winter temperatures usually stay above freezing — exactly the range where a heat pump moves heat at its highest efficiency. One system heats all winter, cools during our warming summers, and modern cold-climate models keep working far below any temperature Clark County typically sees.
Read the guideDuctless mini-splits for garages, ADUs, and additions
A ductless mini-split is usually the best way to condition a space your ductwork never reached — a garage workshop, an ADU, an addition, or a bonus room over the garage. One compact outdoor unit feeds a wall-mounted indoor head that heats and cools that zone independently, with no duct runs, no tearing into finished walls, and no loading extra rooms onto a central system that wasn't sized for them.
Read the guideConverting from a gas furnace to a heat pump: an honest look
Converting from gas to a heat pump works well in our mild climate, but it's not automatically the right call for every home — gas is competitively priced here, so the case usually rests on adding cooling, simplifying to one system, and moving off fossil fuel, not on dramatic bill savings. A dual-fuel system that keeps your furnace as backup is often the smartest first step, and it's a configuration we install and service alongside full conversions.

Moisture, ventilation, smoke season, and the duct problems hiding behind comfort complaints.
HRVs and ventilation: why tight PNW homes need to breathe
Modern energy codes make homes tight, and in the damp Pacific Northwest a tight home without planned ventilation traps moisture — the raw ingredient for condensation, musty smells, and mold. A heat recovery ventilator (HRV) solves it mechanically: stale, humid indoor air goes out, fresh filtered air comes in, and a heat-exchange core keeps most of the warmth you already paid for.
Read the guideDuct design and sealing: the hidden half of home comfort
Your furnace or heat pump only makes the heat — the ducts decide where it goes. In a typical house, ENERGY STAR estimates 20 to 30 percent of the air moving through the duct system is lost to leaks, holes, and poor connections, which shows up as rooms that never get comfortable and bills higher than the equipment's rating promised. Sealing and correcting duct design is often the highest-return fix in the whole system.
Read the guideKeeping indoor air clean during wildfire smoke season
When wildfire smoke rolls into SW Washington, the goal is simple: keep smoke out, filter what gets in. Close up the house, run your HVAC fan with the best filter the system can handle — EPA recommends MERV 13 or as high as your system accommodates — set any fresh-air intake to recirculate, and add a portable HEPA cleaner for the rooms where you spend the most time.
Read the guideRepair, Replace & Sizing
Honest frameworks for the expensive decisions — no sales pitch attached.
Furnace repair or replace? A decision framework that isn't a sales pitch
Repair a young furnace with a cheap, isolated fault; replace an old one facing a major component failure. In between, weigh three things: age against ENERGY STAR's 15-year furnace guideline, the repair quote against the equipment's remaining value, and whether this is the first failure or the third this winter. A cracked heat exchanger is the exception — that's a replacement conversation, full stop.
Read the guideAC sizing for PNW summers: why bigger isn't better here
In SW Washington's short cooling season, the most common AC mistake isn't buying too little machine — it's buying too much. An oversized unit blasts the house cold in minutes and shuts off before it dehumidifies or evens out room temperatures, cycling on and off all day. Right-sizing comes from an ACCA Manual J load calculation of your actual house, not from square-footage rules of thumb or matching whatever was there before.

Verified WA/OR incentive programs and the upkeep that keeps efficiency real.
HVAC rebates & incentives in SW Washington and Oregon: what's real right now
Real money is available, but the details decide everything. Gas furnace rebates run up to $1,600 on qualifying installations. Clark Public Utilities offers $500–$1,250 heat pump rebates and a $900 ductless rebate — for electrically heated homes. Energy Trust of Oregon serves both income-qualified NW Natural customers in SW Washington and Oregon customers of participating utilities. And the federal energy-efficiency tax credit ended for equipment placed in service after 2025, so don't let anyone sell you on it.
Read the guideThe PNW seasonal HVAC maintenance checklist
In SW Washington the rhythm is two seasons: a spring visit readies cooling and clears a winter's worth of debris from outdoor equipment, and a fall visit — the safety-critical one — inspects the furnace's heat exchanger and combustion system before the heating season that does most of the work here. Between visits, your job is simple: filters every 1–3 months, keep the outdoor unit clear, and call when something sounds different.
