24/7 Emergency Boiler Repair in Union, CT
When the January low settles over Union, a boiler that short-cycles or locks out is not a nuisance — it is a race against frozen pipes. Because heating oil leads the fuel mix here (80% oil vs 5% gas), we start with the oil train: Beckett and Carlin primary controls, cad-cell flame eyes, Suntec fuel pumps, nozzle atomization, TigerLoop de-aerators, and tank sludge filter clogs. Dispatch runs along I-84, Route 44, with a typical response of about 46 minutes in Union.

- Only 40% of Union homes predate 1960, but the Hydronic Baseboard systems here still need an annual tune-up before the 6,458-heating-degree-day season.
