Boiler Repair and Installation in Lethbridge

Most boiler calls start with one of a few symptoms. Rooms that won't warm up. Banging or kettling noises when the burner lights. Water dripping from the relief valve, or a pressure gauge that falls below 12 psi every few days. Each points to a short list of causes, like a failed circulator pump, a stuck zone valve, a waterlogged expansion tank, or scale on the heat exchanger. Our boiler repair in Lethbridge starts with a full system check: pressure, pumps, valves, ignition, venting, and a carbon monoxide test. Then we show you what failed and what it costs to fix. Typical repairs include replacing a circulator pump, recharging or swapping the expansion tank, replacing a faulty zone valve or thermostat, and flushing sludge from older cast iron systems. Certified gas fitters do gas work. Call early about small leaks and pressure loss, because a boiler that runs low on water can overheat and crack the heat exchanger, and that's usually where repair stops making sense.

A new boiler should be sized to your house, not copied from the old nameplate. Many homes here have new windows, insulation, or basement developments since the original boiler was installed, so we run a heat-loss calculation for Lethbridge winters, where nights can drop below minus 30°C. An oversized boiler short-cycles and wastes gas. An undersized one can't keep up in February. From there, we'll walk you through the options: high-efficiency condensing gas boilers that run around 95% efficient, combi boilers that handle both heat and domestic hot water, and electric boilers for homes without gas service. We'll explain the running costs of each, since gas and power prices in Alberta shift from year to year. We install brands like Navien, Viessmann, IBC, and NTI. The old boiler gets drained, disconnected, and hauled away, and we tie the new unit into your existing radiators, baseboards, or in-floor loops. Every boiler installation in Lethbridge we complete includes permits, venting, a condensate drain, a system flush, and a test run with you before we leave.

Fall is the best time to service a boiler. Book it in September or October, before the heat runs every day. Southern Alberta chinooks swing temperatures 20°C in an afternoon, and that stop-start cycling wears on burners, pumps, and controls. A tune-up covers cleaning the burner and heat exchanger, testing the relief valve, checking expansion tank pressure, and clearing the condensate trap on high-efficiency units. For in-floor heating systems, we also test the glycol. It breaks down over time and turns acidic, which can eat at pipes and fittings from the inside. Annual service catches worn parts before they fail on the coldest night of January, and it keeps most boilers running well for 20 years or more. You'll also get a short list of any parts that are wearing out, with rough costs, so there are no surprises next season. If your boiler hasn't been serviced in a few years, start there before you think about replacing it. Plenty of "dead" boilers only need a clean burner and one new part.
