Washington State HFC Rules Still Apply Despite EPA R-410A Extension
Washington state homeowners planning a new central air conditioner should know that a recent federal change does not affect them. The EPA recently gave contractors more time to install older R-410A equipment made before 2025, but Washington's own rule still applies on top of federal law. As of January 1, 2026, any newly installed residential air conditioning system in Washington must use a refrigerant with a global warming potential (GWP, a measure of how much a substance contributes to warming compared to carbon dioxide) below 750. That rules out R-410A for new installs, regardless of what the federal rule now allows. State officials confirmed they have no plans to loosen this requirement to match EPA's change. If you already have an R-410A system, you don't need to replace it. State officials said existing equipment can keep running as long as it meets other legal requirements, such as rules against intentionally releasing refrigerant during repairs. Washington also runs a leak-management program for larger equipment, but that mainly targets bigger commercial and industrial systems, not typical home air conditioners. The practical takeaway for anyone shopping for new AC equipment in Washington: ask the vendor to confirm in writing that the system's refrigerant meets the state's GWP limit before you buy. Since rules vary by state, homeowners elsewhere should check what their own state requires, since federal changes don't necessarily override local restrictions.
Air to Water Heat Pump to Replace Aging Boiler for heat and hot water?
A homeowner in Tacoma, Washington is weighing whether to replace an aging, leaking gas boiler with an air-to-water heat pump, a system that heats water instead of air and can run radiators or in-floor heating. Her 1950s house uses radiators and currently needs water at 140 degrees to keep rooms at 68 when it's 20 degrees outside. The bid she's considering, for a SpacePak Solstice unit that would handle both space heating and hot water, comes to $39,550. A building science expert who replied pointed out a key problem: heat pump capacity and efficiency both drop sharply as the water gets hotter. At 95 degree water, this unit puts out far more heat and uses less electricity than it does at 140 degrees, where it delivers barely half the heat for almost twice the power use. So the real question isn't whether the heat pump can work, it's whether the house can be heated with cooler water than the old boiler used, since the boiler's 140-degree setting may just reflect its minimum, not what the house actually requires. For homeowners in a similar spot, the lesson is that swapping a boiler for a heat pump isn't a simple one-for-one trade. It helps to know your actual heating load and the lowest water temperature your radiators or floor heating can work with before signing a contract. The expert also noted that a dedicated heat pump water heater, rather than asking the same unit to do double duty, often costs less to install and run for domestic hot water.
