About Miller & Sons Heating & Cooling
Miller & Sons Heating & Cooling has served Molalla and surrounding Oregon communities for multiple decades as a family-owned heating contractor. Based at (503) 829-7979, the company maintains standard weekday hours from 8 AM to 5 PM and currently holds a 3.7-star average across 15 verified customer reviews. The business operates as a heating-focused contractor, specializing in gas furnace repair, replacement, and installation services for residential properties throughout the greater Molalla area.
What distinguishes Miller & Sons from other regional contractors is their commitment to rapid response and problem-solving efficiency. Multiple reviews specifically mention same-day service availability, with technician Mal completing a full furnace installation within 24 hours of initial contact. Their diagnostic precision has repeatedly identified simple issues that previous contractors misdiagnosed as major component failures, saving homeowners unnecessary expense. The company handles gas line installations for appliance upgrades and provides ongoing maintenance services for rental properties.
Customer narratives from recent reviews reveal specific service scenarios that illustrate their capabilities. Heather Carter's gas heater was diagnosed and repaired in 20 minutes, resolving an issue another company claimed required new parts. Mike Roth experienced a complete Tuesday-afternoon furnace failure resolved with a new unit installed and operational by 4:30 the following afternoon. Technician Mal has also serviced rental properties for out-of-state property managers, providing access and documentation for tenants.
What Customers Say
5 of 7 reviewed customers awarded 5-star ratings, specifically praising same-day response, diagnostic accuracy, and technician Mal's professional demeanor. Both 1-star reviews describe the same incident involving audible profanity from a contractor on a job site, representing a recurring concern in client-facing conduct.
