A notable trend in HVAC and refrigeration is that contractors are increasingly repairing faulty aluminum coils and return bends rather than ordering new parts. Two factors are driving this change: supply chain breakdown and shorter manufacturer warranty periods.
While the supply chain issues seem to be easing a bit, it’s been a frustrating couple of years of long waits to get new parts and it’s been tough to keep them stocked. And obviously when equipment fails — especially in refrigeration — there's no time to wait for the weeks or months it could take to get a new part.
