What Efficient Means on a Castle Rock Listing

  • The HERS score. New Castle Rock builds carry a Home Energy Rating: 100 is a code home, 50 uses half the energy, 0 is net zero. Ask for the certificate.
  • Envelope first. Windows, insulation and air sealing beat any furnace. A 1970s Castle Rock home with new windows and attic insulation outperforms a 2005 build with the originals.
  • Heat pumps. Cold-climate heat pumps heat and cool below zero and cut the gas bill. Xcel and federal rebates cover a real share.
  • Solar and storage. Owned panels add value; leased panels transfer a contract. Ask which before you write.
  • The bills. Sellers can pull twelve months of Xcel history. We ask for it on every efficient home in Castle Rock.

Castle Rock Questions

Do energy-efficient homes cost more in Castle Rock?

New net-zero builds list a few percent above code builds and pay it back in bills. Updated older homes sell near the neighborhood price with lower running costs.

What rebates are available?

Federal tax credits for heat pumps, solar and insulation, Xcel rebates for heat pumps and smart thermostats, and Colorado's state credits. Your lender and your Kenna agent list what applies.

Is a HERS score important?

On a new build, yes; it is the one number that compares homes. On an older home, the utility bills and the upgrade list do the same job.

Yes. Call or text 303-955-4220 and a Kenna agent meets you there, 7 days a week.
