GuidesOutdoor condenser, indoor coil, compressor, blower, refrigerant lines, and a drain. Knowing which box is which keeps a no-cool call from turning into a parts guess.

GuidesUnvented propane heat in a closed room is a carbon monoxide and moisture problem. Vented appliances and outdoor-rated heaters are different tools. Gas odor means leave.
Read articleGuidesAn ECM is the variable-speed blower motor in many newer furnaces and air handlers. When it fails, the module and the motor are not always the same part, and it is not a DIY swap.

TroubleshootingA high-efficiency furnace makes water on purpose. A puddle means that water is not leaving through the drain, or the leak is something else entirely.
Read articleTroubleshootingMost refrigerants have little or no smell. A sweet or chemical odor near the indoor coil is a clue, not a diagnosis, and it is not something to hunt by sniffing.

GuidesCFM is cubic feet per minute, the amount of air the blower is moving. Comfort problems are often a CFM problem in a room, not a tonnage problem at the condenser.

Read articleCase studiesA clean filter protects your blower, keeps air flowing, and helps your furnace run efficiently. Here is a practical schedule for Vancouver-area homes.
Read articleTroubleshootingFive checks outside the cabinet: thermostat, filter, the furnace switch, the breaker, and whether the outdoor heat pump is buried or iced solid. Then stop.
Read articleguidesCheck the furnace filter, vents, and thermostat before the cold stretch, and learn which first-startup smells fade on their own.

TroubleshootingThe usual HVAC cause is electric resistance heat doing the work a heat pump should be doing. A dirty filter, emergency heat left on, or a heat pump that is not running will do it. The dollar amount depends on your rates.
Read articleGuidesR-454B is a refrigerant showing up in new equipment as R-410A is phased down. It is not a drop-in for an older system, and it is not something to add from a can.

TroubleshootingA thin film of water while the air conditioner runs can be normal condensate. A pan that stays full, overflows, or holds water when the system is off is a drain problem.

Case studiesA Vancouver, WA couple with a newborn was told their 17-year-old Rheem AC needed a $30,000 replacement. A second opinion found the real issue — a faulty Schrader valve core — and repaired it the same day for $946.
Read articleMaintenanceThe outdoor coil can be rinsed if the power is off and you stay out of the electrical compartment. Bent fins and a pressure washer do more harm than cottonwood.
Read articleGuidesThe TXV meters refrigerant into the indoor coil. Homeowners do not adjust it. Wrong readings show up as poor cooling or a frozen coil, and the fix is a diagnosis, not a twist of the valve.
Read articleGuidesThe plenum is the box where the furnace or air handler meets the ducts. Leaks, a fallen liner, or a disconnected takeoff make rooms wrong before the equipment is wrong.
Read articleTroubleshootingCooling makes water on purpose. It leaks into the house when the drain, the pan, or a frozen coil sends that water somewhere other than the drain line.
Read articleTroubleshootingStart with the thermostat mode, the filter, and whether anything is trying to run. Gas odor or a carbon monoxide alarm means leave. The rest is a diagnosis, not a new furnace by default.
Read articleTroubleshootingMost of the switch is the thermostat: mode to Heat, fan on Auto, and a setpoint above the room. What you do next depends on whether the house has a furnace or a heat pump.

Case studiesA Vancouver, WA homeowner's AC stopped blowing cold air because of a seized condenser fan motor. We replaced it with OEM parts, performed full maintenance, and solved their uneven upstairs temperatures with ductwork modifications.
Read articleGuidesHold keeps the temperature you set instead of letting the schedule change it. It is not a lock on the furnace, and it is not a repair mode.

TroubleshootingThe contactor is the heavy switch that sends power to the compressor and condenser fan. Pitted contacts and a stuck plunger are tech diagnostics, not a screwdriver job.
Read articleIndoor Air QualityA damp room after the heat comes on is usually moisture and airflow, not a broken furnace. Check exhaust and the filter before you add equipment.
Read articleGuidesThe gas valve opens only when the furnace has proved it is safe to light. It is not a knob to turn, and it is not something to jumper.

Case studiesA Camas homeowner couldn't sleep upstairs during summer. The real problem wasn't the 22-year-old AC — it was undersized ductwork in the attic. Here's how we fixed it with proper airflow design, dampers, and additional registers.
Read articleGuidesMCA is the minimum wire ampacity. MOCP is the largest breaker or fuse allowed. They are not the same number, and neither one is a homeowner adjustment.
Read articleMaintenanceKeep the outdoor coil clear, leave emergency heat off, and change the filter. Ice that never clears and a heat pump that never runs are repairs, not a reason to buy a new one on the spot.
Read articleGuidesA PSC motor is the older single-speed blower. It needs a run capacitor. A hum and no airflow can be that capacitor or the motor, and the capacitor can still shock you after the power is off.
Read articleTroubleshootingIf an air conditioner is low on refrigerant, it leaked. Adding refrigerant without finding the leak does not last. Airflow problems mimic the same symptoms.
Read articleTroubleshootingThe run capacitor helps the compressor or fan motor start and keep running. A failed one is a common outdoor-unit fault. The part stores energy, so it is not a homeowner swap.
Read articleTroubleshootingShort cycling means the outdoor unit starts and stops before the house is cool. Airflow, the thermostat, and a failing capacitor are more common than a unit that is suddenly too big.
Read articleGuidesA recovery wheel is a rotating core that passes heat and moisture between exhaust air and fresh air. Most houses use a fixed ERV core. Wheels show up on larger equipment.
Read articleTroubleshootingFrozen coils, dirty filters, and refrigerant issues are common reasons cool air stops reaching your vents. Here is what to check and when to call a pro.
Read articleGuidesBTU per hour is the cooling capacity, not a quality score. Bigger than the house needs is a worse air conditioner, because it short cycles and leaves humidity behind.
Read articleGuidesA condensate pump lifts furnace or air conditioner water when there is no drain below the unit. If it fails, the float should shut the system off before the pan overflows.
Read articleMaintenanceA furnace filter protects the equipment and catches some dust. It is not a medical device. A packed filter can make the house dustier and the system louder, and it should be changed for the right size.
Read articleGuidesA return is how the system gets air back. Covering it does not save energy. It starves the blower, and the rooms you were trying to fix usually stay uneven.
Read articleGuidesDual fuel pairs a heat pump with a gas furnace. The heat pump heats most of the time. The furnace takes over when the outdoor unit is no longer the right tool. Cost depends on the house and the rates, not a slogan.
Read articleTroubleshootingWarm air, weak airflow, odd sounds, or spiking bills often mean your AC needs attention before a small issue becomes a mid-summer breakdown.
Read articleTroubleshootingA blank thermostat is a power problem. Batteries, the furnace switch, a tripped breaker, or the door switch are the checks. The wiring behind it is not a guessing game.
Read articleGuidesA dual-zone mini split is one outdoor unit and two indoor heads, each with its own setpoint. It fits some rooms. It is not automatically the right fix for a whole house.
Read articleGuidesAn energy recovery ventilator brings outdoor air in and sends stale air out, and it transfers some heat and moisture between the two streams. It is ventilation, not an air conditioner.
Read articleTroubleshootingA once-a-minute chirp is often a battery or an expired detector. A full alarm means get everyone outside and call emergency services. Do not pull the battery and leave it that way.

Retrieving my belongings turned into a bigger hassle than expected. The staff couldn't locate some boxes right away, and I spent far too much time trying to sort things out.
Our AC broke and wasn’t cooling at all, so we called Sub Zero Temp Control for AC repair. They came out, checked the problem, and gave us a clear quote with a fair price before starting any work. The repair took about 2 hours and the air conditioner was cooling again the same day. Honest pricing and solid HVAC repair…
I hired this local business to inspect my older climate equipment just to make sure it was ready for the upcoming heatwave. They replaced a rusty contactor switch and gave me great peace of mind without charging a huge fee.
