HVAC Service in Kelso, WA
Consistent Climate is based right here in Kelso. Nathen Scott has been servicing Kelso homes for years and knows the housing stock, the local utilities, and what it takes to keep a Cowlitz County home comfortable through every season.
Your Local HVAC Contractor
A lot of HVAC companies serving Kelso are based out of Portland or Longview and treat this area as a secondary market. Consistent Climate is different. Nathen lives and works in Kelso, which means faster response times, no travel markups, and a contractor who has a real stake in the reputation he builds here.
Many Kelso homes were built in the 1960s through 1980s and still have original duct board that has long since degraded. Nathen has replaced hundreds of these systems and knows exactly what to look for. If your ductwork is the problem, he'll tell you - and if it isn't, he'll tell you that too.
As a Bosch Authorized Dealer, Nathen installs AHRI-certified equipment that qualifies for Cowlitz PUD rebates, helping offset the upfront cost of a new system.
Cowlitz PUD Rebates
Kelso homes served by Cowlitz PUD can qualify for rebates when upgrading to a qualifying heat pump or ductless system. Bosch equipment installed by Consistent Climate meets the AHRI certification requirements for these rebates.
