Jason and David arrived on time and were very courteous. They took their shoes off so my floors didn’t get dirty. I contacted them for a bid and look forward to hearing what they submit.
I had an awesome experience with Efficiency Heating and Cooling. They were super professional and highly communicative. I really appreciated their transparency around pricing, status updates, resolving an issue with a delayed part.

I want to give a special shout out to the tech, Jim. He was 100% committed to getting the job done right and was super thorough in explaining what needed to be done. He was extremely professional and even toughed through listening to my dog bark on and on for an hour while he worked (sorry about that again)!

Highly recommend these folks for your HVAC needs and they will be my go to from here on out. Thank you!!
Tristan provided a very clear assessment of the issues and was very professional.
Technician showed up early, checked for causes of the water leakage, found the broken pump, replaced it with a new one (he already had with him), and had everything cleaned up within a short time. He explained the problem clearly, and gave the full price before proceeding with the repair. I appreciated being able to phone my husband beforehand. Also, the technician advised me to launder the wet towels sooner rather than later. He was excellent, and we would recommend him to anyone.
Polite, patient and clear. Happy with the service.
Went above and beyond
Professional, punctual, knowledgeable and thorough in service provided and cordial. Much appreciated.

Why homeowners choose our Lake Oswego HVAC Contractors

Climate & Heating Needs in Lake Oswego

  • Cool, damp winters with morning fog and lake inversions make homes feel colder than the thermostat reads.
  • Summer highs plus lakeside humidity raise cooling loads around Oswego Lake and tree-canopy streets.
  • Two-story and open-plan homes benefit from variable-speed heat and smart zoning for even rooms.

Lake Oswego Property & Maintenance Challenges

  • Cottonwood and tree pollen from Tryon Creek and the Oswego Canal clog filters and outdoor coils each spring.
  • Mid-century crawlspace ducts and additions in Lake Grove/First Addition cause hot–cold rooms without sealing/balancing.
  • Quiet neighborhoods (Westlake, Uplands, Palisades) call for low-noise equipment and careful condenser placement—ductless is often ideal for offices and suites.
  • Tight remodels near Kruse Way need balanced ventilation and humidity control to keep IAQ healthy.

Air Quality & Comfort Solutions Lake Oswego

  • MERV 11–13 media filtration, sealed return drops, and periodic duct cleaning to cut pollen and wildfire smoke particulates.
  • Fresh-air/ERV strategies with dehumidification for tighter envelopes and shoulder-season moisture.
  • Zoned comfort plus variable-speed heat pumps or dual-fuel systems for steady temps and very low sound.

How Oswego Lake’s micro-climate changes the HVAC playbook in Lake Oswego

Morning inversions and tree-canopy shade around Oswego Lake make winters feel damper and summers stickier than nearby neighborhoods.

Mid-century crawlspace ducts in First Addition and Lake Grove can leak heat, while newer builds near Kruse Way are tight enough to need balanced ventilation.

Our approach is simple: right-size equipment, verify airflow/static pressure, and match filtration/ventilation to your home so comfort stays steady without wasting energy.

Homes we most often service around the lake

  • Mid-century ranches/splits in Lake Grove & First Addition with original ducts and cool back bedrooms.
  • Two-story homes in Westlake, Palisades, and Uplands that benefit from quiet, variable-speed systems and zoning.
  • Townhomes/condos near Lake Grove Village Center where compact, low-noise placement matters.

Furnace Repair in Lake Oswego — steady heat on foggy mornings

Early clues to fix before it becomes a no-heat call

  • Short cycling or long run times after damp, near-freezing nights.
  • Back rooms never meeting setpoint (usually balance or leakage).
  • Musty/burning odors at first start-up from dust and moisture on the heat exchanger.

When heat isn’t right, we begin with combustion safety, CO, draft, and static-pressure tests to find root causes—then we recommend the least-disruptive fix first. Need help now? Book priority furnace help and we’ll get you warm fast.

Furnace installation & replacement for Lake Oswego homes

If repairs keep stacking up or your unit is 15–20 years old, a sealed cabinet with an ECM blower and smart thermostat stabilizes temperatures and lowers noise—ideal for quiet streets around the lake. We right-size to real heat loss and verify ducts so the new system delivers what it promises. Our fall tune-ups keep warranties intact and efficiency high.

Air Conditioning Repair in Lake Oswego — quiet cooling near the lake

Central vs. ductless—match the system to your rooms

Variable-speed central AC excels in larger layouts and dehumidification; ductless shines in lake-level offices, studios, and additions where zoning and sound matter. If your unit struggles on muggy afternoons or after cottonwood season, schedule quick AC diagnostics. Planning ahead? Compare options and plan a new AC system sized to your rooms, noise goals, and budget.

AC maintenance tuned to Oswego Lake conditions

Book spring service before cottonwood to keep coils clean and charge correct. We check airflow, drain performance, and cabinet sealing so humidity control stays on point through July/August heat.

Heat Pump Installation in Lake Oswego — efficient, low-noise comfort

Cold-climate heat pumps hold output on chilly mornings and deliver even, quiet heat—no “blast furnace” feel. Dual-fuel pairs with an existing gas line for rare deep-cold spells. Considering a switch? Start with a modern heat pump setup that’s right-sized for hillside exposures and tight envelopes near Tryon Creek.

Heat pump maintenance & long-life performance

Keep efficiency high with a seasonal check for heat pumps. We verify defrost logic, refrigerant charge, airflow, and condensate management so winter comfort stays steady and summer bills stay in check.

Air quality & ductwork for pollen, lake humidity, and smoke

Small upgrades that make a big difference in LO homes

  • MERV 11–13 media filtration (properly sealed) to capture cottonwood, maple/fir pollen, and wildfire particulates.
  • Sealed return drops and duct balancing to eliminate dusty drafts and hot/cold rooms.
  • Fresh-air/ERV strategies with humidity control for tighter remodels near Kruse Way & Foothills.

If allergies or dust are constant, start with duct cleaning for allergies; we’ll pair it with the right filter and airflow tweaks for your space.

Light-commercial care for Kruse Way & Foothills businesses

From professional offices along Kruse Way to boutique retail near Foothills Park, we provide planned maintenance, rapid diagnostics, and replacements scheduled around your hours—with clean documentation for owners and property managers.

Lake Oswego HVAC FAQs

When should I schedule an AC tune-up near the lake?

Late spring—before cottonwood and early heat. Early service improves efficiency and reduces mid-summer breakdowns.

Can a heat pump keep up on foggy mornings?

Yes. Cold-climate models maintain capacity at lower temps; dual-fuel adds backup for rare deep-cold spells.

What fixes a back bedroom that never warms up?

Start with a static-pressure test; seal leaky returns and balance branches. If the system’s oversized, a variable-speed blower and right-sizing plan even out temps.

How do I protect indoor air on smoke days?

High-MERV filtration in a sealed cabinet, a clean coil, and verified duct integrity. During heavy smoke, run recirculation and replace filters sooner.
