Lochinvar Boiler Maintenance

What a proper Lochinvar service includes

• Inspect the heat exchanger and combustion chamber.
• Check gas pressure with a manometer and run combustion analysis.
• Test safety devices — relief valve, high-limit and pressure controls.
• Inspect the flue and venting for integrity and clearance.
• Check system pressure and the expansion tank charge.
• Clean and check the condensate trap and drain — a common cold-weather shutdown point on condensing models.
• Inspect the domestic-hot-water plate heat exchanger and flow sensor for scale and debris.
• Inspect the fire-tube heat exchanger — durable, but combustion still needs verifying yearly.
• Confirm Wi-Fi / connected controls and firmware are working so alerts and scheduling function.
• Clean the burner and flame-sensing electrode and re-run combustion analysis.

How often to service a Lochinvar boiler

Once a year is the standard for residential Lochinvar boilers — ideally in late summer or early autumn, before the heating season. Heavily-used, older or commercial installations may warrant more frequent checks. Skipping services is one of the most common reasons a manufacturer warranty claim is later refused.

Lochinvar servicing — what to expect

Our Lochinvar maintenance starts from $169, with upfront written pricing before any work begins. A thorough service typically takes around an hour, and you receive a record of what was checked and done — useful for warranty and, in rentals or stratas, for proving the appliance was maintained.
