HVAC Business Valuation: SDE, EBITDA, and the File a Buyer Reads

Auxo’s fetched page puts smaller shops near 2.5x–4.0x SDE and scaled shops near 3.5x–7.5x+ EBITDA. Capstone’s 14.0x is disclosed M&A. Not an appraisal.

Reverse Osmosis Membrane: When the Reduction Falls Off

GE Appliances says replace the membrane when TDS reduction falls below 75 percent, check TDS yearly, and change pre and post filters about every six months.

Sediment Filter Replacement: Months, Pressure, and One Manual

Pentair’s Pelican PSE1800-P and PSE2000-P manual says every 6 to 9 months, or when pressure slows. The steps are for that blue housing. No price.

A2L Refrigerant: What HVAC Contractors Need to Know

ICC lists R-454B and R-32 as A2L refrigerants and does not list R-410A. EPA’s sector table is quoted with its dates. Not a ban line, and not a safety procedure.

Water Softener Settings: Hardness, Iron, and Salt

Type grains per gallon from a test. Iron compensation only if the valve manual prints one. Regeneration and salt dose stay on their calculators.

Portable Water Softener: Renters, RVs, and a Hose

A tank you can carry, regenerated with salt, limited to the hose it is on. No brand rank and no grain capacity copied from a shop page.

Water Softener for Well Water: Test Before You Treat

EPA says to test a private well every year for coliform, nitrates, dissolved solids, and pH. NDSU’s iron limits decide whether a filter comes before the softener. No brand is picked.

Purolite says a premium cation resin can run over ten years when the system is run correctly, and under a year when chlorine and iron are ignored. No valve year is added.

Water Softener Brine Tank: Salt, Brine, and the Short Tank

EPA's May 2026 guide calls the brine tank the shorter tank beside the resin tank. Fill about half full. A salt bridge is a fused layer. No bleach dose is printed.

How to Clean Water Softener Resin and the Brine Tank

EPA says to use the manufacturer's resin cleaner once a year and to wash an empty brine tank with soapy water and a bleach solution. No ratio is printed.
