Building a Profitable HVAC Business by Putting People, Not Revenue, First
This is a story about how one HVAC company runs its business, not a rule change or rebate update, so there's no direct action for homeowners. But it does offer a useful window into what to expect from a well-run heating and cooling contractor. Anchor Heating & Air, a Charleston, South Carolina company founded in 2021, built its business around hiring experienced technicians rather than cheaper, less-trained ones, and around pricing that reflects real costs rather than rock-bottom quotes. The idea is fewer callbacks, fewer mistakes, and technicians who take time to explain options instead of pushing a sale. The company's co-founder says her technicians are told to educate homeowners rather than pressure them, and that customers sometimes take years to decide on a system replacement without any hard sell. She also points to community involvement, sponsoring local events and charities, as part of how the company builds trust with the people it serves. For a homeowner evaluating any contractor, the takeaways here are less about dollar figures and more about signs of a solid operation: technicians with real experience, straightforward pricing, and a willingness to let you decide on your own timeline rather than rushing you into a system replacement. None of this points to a specific program, rebate, or deadline, it is simply a look at one company's approach to doing business.
Santee Cooper’s New Energy Plan is Bad News for South Carolina Customers
Santee Cooper, the South Carolina utility, has filed a new long-range energy plan with state regulators that pulls back on earlier solar commitments and keeps a coal plant running longer than planned. Back in 2023, the utility had proposed 1,500 megawatts of solar by 2030 and 3,000 by 2040. The new plan pushes solar investment off until 2052. It also delays the retirement of the Winyah coal plant from 2030 to the end of 2034, with the door left open to pushing that date back further. The utility says rising electricity demand, partly from data centers, is driving up costs, and it wants to build new gas plants rather than lean more on solar and wind. Critics point out that solar and wind are generally the cheapest new power sources available right now, and that a global shortage of gas turbines is already pushing up prices. South Carolinians have also raised concerns about cost overruns at the Canadys gas plant currently under construction. For homeowners, this is a signal about where your electricity is likely headed, not a program you can sign up for. If your utility leans harder on new gas plants and delays shutting down an aging coal plant, that can mean higher power bills over time, since gas and coal costs have been less predictable than solar. It is also a reminder that utility planning decisions made now, long before they show up on a bill, shape what you pay for electricity for years to come.
After third-party safety tests, Silfab will start solar cell production in SC next month
Silfab Solar plans to start up its solar cell manufacturing plant in Fort Mill, South Carolina, on October 19. The facility had been closed earlier this year after a chemical incident raised safety concerns among nearby residents, since making solar cells involves handling chemicals like silane, anhydrous ammonia, hydrochloric acid, potassium hydroxide, and hydrofluoric acid. Before restarting, Silfab hired an outside firm, TRC Engineers, to review its leak prevention and emergency response systems. TRC's report found that Silfab's equipment and safety features already met or exceeded regulatory requirements, and the company has shared that report with South Carolina's environmental regulators. TRC also recommended some additional safeguards, such as more leak detection systems, alarms, and shut-off valves throughout the plant. Silfab says it has already made some of these upgrades and will complete the rest as production lines come back online. This news mainly matters if you live near the Fort Mill plant or are following the solar manufacturing industry rather than shopping for a home solar or efficiency upgrade yourself. It does not change pricing, incentives, or panel availability for homeowners considering solar installations. Silfab has posted the full report and its restart plans on its own website for anyone who wants more detail on the safety review or the timeline for resuming operations.
