Frequently Asked Questions (FAQs)

How do I know if my boiler is a low pressure boiler?

Residential heating boilers are commonly classified according to their design, temperature, and pressure ratings. Steam and hot-water boilers have different pressure limits, so the operating pressure alone doesn’t necessarily identify the boiler’s classification. The manufacturer’s rating plate provides important information about your system. If you’re unsure, our technicians can help identify your boiler type and explain its operating requirements.

How often should I check my boiler’s pressure?

We recommend checking your boiler’s pressure gauge monthly. Maintaining proper pressure helps prevent breakdowns and inefficiencies. Normal pressure readings vary by boiler design and manufacturer.

How often should an oil boiler be serviced?

Oil-fired boilers generally benefit from professional maintenance at least once a year, ideally before the heating season. Maintenance can include checking burner operation, cleaning combustion-related components, inspecting safety controls, and evaluating system performance. Your boiler’s manufacturer may recommend additional maintenance based on its design and usage.

Can you repair oil boilers in winter?

Absolutely! Our technicians are experienced in providing emergency repairs for oil boilers, ensuring your home remains warm and comfortable even during Montana’s coldest days.

What maintenance is required for combi boilers?

Combi boilers require annual maintenance to clean heat exchangers, inspect controls, and ensure safe, efficient operation.

Are combi boilers good for large homes?

Typically, combi boilers are best suited for smaller to medium-sized homes. For larger homes, our technicians may recommend other boiler systems better suited to handle higher demand.

What are common signs of a failing oil boiler?

Common signs include unusual odors, soot buildup, inconsistent heating, frequent cycling, or increased oil consumption.

Should I repair or replace my boiler?

This decision depends on the boiler’s age, efficiency, and the cost of repairs. Our technicians will provide an honest assessment to help you make the best choice.
