How We Write
This is a contractor's blog, not a content farm. Every article goes through the same in-house standard before it's published — no exceptions, no AI shortcuts, no syndicated boilerplate.
Written by the Trade
Heat pump articles are reviewed by a Mass Save Heat Pump Contractor. Electrical articles are reviewed by a Master Electrician. No generalist staff writers.
Real Numbers Only
Cost ranges come from invoices we've actually issued. Rebate amounts cite the live Mass Save table. Code references cite 780 CMR with section numbers, not paraphrased summaries.
Updated, Not Republished
When Mass Save changes a cap or 780 CMR adopts a new edition, we update the existing article and stamp the change date. We don't republish the same content under a new headline.
Information Gain
Each article has to add something the rest of the internet doesn't. If a topic has 50 generic guides, we either bring primary data, a cost breakdown, or a code citation — or we don't publish.
