New Oregon policy prohibits building homes with AC-only units: 'Codes like these are necessary'

Under a new Oregon residential energy code, new houses built in the state must be equipped with heat pumps that can both heat and cool rather than traditional units that can only provide air conditioning. 

The state-mandated change is not only projected to save residents around $125 per month on their energy bills but also help curb pollution in local communities. 

As Smart Cities Dive reported, the Oregon Building Code Division's Residential and Manufactured Structures Board recently approved the measure. Going forward, all new-construction buildings must have energy-efficient heat pumps, as outdated AC units are no longer allowed. 

This decision will benefit residential energy customers, as experts anticipate natural gas utility rates to increase by nearly 60%. Last year, the Beaver State had to double its funding for the energy assistance program to help low-income families pay their utility bills. 


Regardless of where you live, heat pumps can be a sustainable and efficient way to lower energy costs. Trusted companies such as Mitsubishi can help you find the right heat pump option for your home, including cost-effective mini-split systems. 

In Oregon, the new building code is expected to save homeowners over $1,700 annually. 

"As heat pump technology improves, codes like these are necessary to ensure that new buildings are taking full advantage of the benefits that these high-efficiency, non-polluting appliances offer," Dylan Plummer of the Sierra Club said

When you upgrade to a heat pump, you can stay comfortable in your house even during cold weather. Compared with natural gas and other traditional heating and cooling systems, heat pumps also help you reduce harmful air pollution in your area.
