Missed opportunity to discuss GSHPs and instead pushes electric HPs because it's a business blog masquerading as a .org to push product.
And also, contractors and maintenance shops push products that minimize their costs and maximize their profits. It's also why private equity owns effectively every high voltage motor capacitor manufacturer in the US and why those capacitors have such short lives now. It's not about minimizing TCO, it's about maximizing customer dependency upon service and parts without seeming there is any other choice balanced with the stochastic equilibrium of potentially more reliable alternatives threatening this "cottage" industry.
PS: clean your coils, change your air filters (without excessive MERV flow restriction), surge protect ECMs, and check your caps.
