Top 7 HVAC companies in Marion, Oregon

Marion County, Oregon, sits in a marine climate zone where winter heating loads dominate yet recent heat waves have increased demand for air conditioning and heat pumps. Public listing data collected on 2026-08-16 supplies review counts, star ratings, addresses and contact numbers for seven firms that appear in search results for HVAC work. The list is ordered by a Bayesian-adjusted rating that pulls each company's raw score toward the national mean of 4.764. Companies with fewer reviews experience larger adjustments. This produces a shortlist drawn solely from public records rather than from on-site inspections or interviews.

The shortlist

Companies are ranked by a Bayesian-adjusted rating: a company's star rating is pulled toward the national mean until it has enough reviews to stand on its own, so a 5.0 from four customers does not outrank a 4.9 from two hundred. Small tie-breakers apply for a public website, for being listed as an HVAC specialist rather than a general contractor, and for published 24/7 availability. This is a shortlist built from public listing data, not a review of work performed.

Valley Flow Air Solutions

Valley Flow Air Solutions operates from 1407 N 1st St, Silverton, OR 97381 and lists the phone number (503) 930-6116. Its 94 reviews produced a raw rating of 5 that the adjustment pulled down to an adjusted score of 5.003 because the national mean sits at 4.764 and the large review count limits movement. The firm appears as a general contractor and publishes 24/7 availability along with a website. These signals place it first. The numbers cannot reveal how the company handles permit filings or how its crews perform on complex retrofits.

DiMartino's 5 Star Heating & Air Conditioning

DiMartino's 5 Star Heating & Air Conditioning is located at 270 Elma Ave NE, Salem, OR 97301 and can be reached at (503) 991-5506. With 92 reviews the raw 5.0 rating receives a modest downward adjustment to 5.002, still above the national mean of 4.764. The listing shows a services category plus a website and 24/7 availability. Those factors secure second place. Review volume is high enough that the score moves only slightly, yet the data set supplies no information on recent complaint resolution or parts sourcing.

Oregon Healthy Homes LLC.

Oregon Healthy Homes LLC. lists its address as 19450 SW Mohave Ct, Tualatin, OR 97062 and the phone number (971) 570-9097. Its 105 reviews support a raw rating of 5 that adjusts downward to 4.988 because the national mean is 4.764. The general-contractor listing includes a website but omits 24/7 service, which places the firm third. The review count is sufficient to keep the adjusted score close to the raw value. The figures give no indication of actual job-site practices or warranty handling.

Freedom Heating and Air

Freedom Heating and Air operates from 909 Edgewater St NW, Salem, OR 97304 and lists the phone number (503) 580-1456. Seventy-four reviews yield a raw rating of 4.9 that the adjustment lowers slightly to 4.901. The national mean of 4.764 sits below the raw score, so the movement is modest. A website appears in the listing but 24/7 availability does not, producing fourth place. The numbers cannot disclose technician training levels or how the firm manages peak winter calls.

Air Systems of Southern Oregon LLC

Air Systems of Southern Oregon LLC is based at 139 Greenview Dr, Eagle Point, OR 97524 and the phone number is (541) 879-0871. Only nine reviews support the raw rating of 5, which the adjustment lowers to 4.858 because the small sample size allows greater pull toward the national mean of 4.764. A website is listed and the category is general contractor. The limited review count keeps the firm in fifth position. The data set supplies no detail on how the company performs outside its listed service area.

C.J. Hansen Company, Inc.

C.J. Hansen Company, Inc. is located at 3552 Silverton Rd NE, Salem, OR 97305 and lists the phone number (503) 362-3643. Forty-five reviews produce a raw rating of 4.3 that the adjustment raises to 4.526 because the score sits below the national mean of 4.764. The general-contractor listing includes a website. These factors determine sixth place. The numbers cannot show whether recent jobs met current code or how quickly the firm resolves callbacks.

Gagle's Heating

Gagle's Heating maintains its address at 2789 Pringle Rd SE, Salem, OR 97302 and the phone number (503) 581-2972. Its 118 reviews support a raw rating of 4.3 that the adjustment raises to 4.434 as the national mean of 4.764 exerts upward pressure. The general-contractor category lists a website. The review depth produces a smaller adjustment than for firms with fewer entries, resulting in seventh place. The figures offer no information on how the company manages refrigerant recovery or electrical tie-ins.

How to choose

Begin with CCB registration verification through the public lookup tool and confirm the Limited Maintenance Specialty Contractor HVAC/R endorsement. Cross-check BCD technician licenses for any crew members performing limited-energy work. Ask whether the firm participates in the Energy Trust Trade Ally network, which adds documented training and inspection layers. Compare the published review counts and adjusted scores rather than raw star ratings alone. Request written confirmation that the contractor will obtain the required local permit.

Cost

Installed costs for a full residential system in the county range from $10,100 to $12,300, with a typical figure of $11,200. Separate 2025 invoiced data show an average of $22,487 and an upper-quartile price of $32,761. The two sources disagree because one reflects contractor-reported averages while the other captures actual billed amounts that may include larger or more complex jobs. Labor is listed at $140 per hour. Permit fees fall between $150 and $500 depending on jurisdiction. Marion County sits in the high-cost tier relative to national figures.

Climate

Marion County falls primarily in IECC zone 4C with marine moisture conditions west of the Cascades. Heating degree days total 4,400 while cooling degree days reach only 400, confirming a heating-dominant load profile. Winter design temperature is 27 °F and summer design reaches 89 °F. Mild damp winters give way to dry summers, yet recent heat waves are accelerating heat-pump and central-AC adoption. Equipment must therefore handle substantial heating hours while remaining efficient at moderate summer loads. Proper sizing remains critical because oversizing reduces dehumidification performance during shoulder seasons.

Licensing and permits

Licensing occurs at the state level through the Oregon Construction Contractors Board for business registration and the Oregon Building Codes Division for individual technician licenses. Required credentials include the Limited Maintenance Specialty Contractor HVAC/R business license and Class A or B Limited Energy Technician licenses. The CCB mandates a surety bond and general liability insurance at minimum amounts that vary by license scope. Permits for furnace or air-conditioner replacements are not issued statewide; each city or county building department handles its own permits, and replacement work remains subject to the Oregon Building Code. Homeowners must confirm the local authority having jurisdiction before work begins.

Incentives

Oregon Home Energy Rebates, administered by the Oregon Department of Energy, carry a maximum heat-pump rebate of $8,000 and are scheduled to launch late 2025 or early 2026. Energy Trust of Oregon offers separate ratepayer-funded rebates between $1,000 and $3,000, but only through its Trade Ally contractor network. No state income-tax credit remains after the 2017 sunset of the Residential Energy Tax Credit. Federal 25C and 25D credits expired at the end of 2025, leaving no residential HVAC tax credit available in 2026. These rules mean homeowners seeking rebates should restrict initial conversations to Trade Ally firms that already carry the required CCB endorsement.

Public data alone cannot confirm workmanship quality or current insurance status. Verify every CCB number, request local permit details, and confirm Energy Trust participation before signing a contract.
