Our Boiler Repair Process

Simple, Transparent Repair Process

First, you call and describe what’s happening with your boiler. We ask specific questions to understand the problem and schedule a convenient time for diagnosis. Emergency situations get priority scheduling.

When our technician arrives, we perform a thorough inspection of your boiler system. We check the obvious issues first – thermostat settings, pilot lights, circuit breakers – before moving to more complex diagnostics. You get a clear explanation of what we find.

Once the problem is identified, you receive an upfront estimate for the repair work. No surprise charges or hidden fees. If you approve the work, we complete the repair using quality parts and test the system thoroughly before leaving. You get documentation of the work performed and recommendations for preventing future issues.

Complete Boiler Repair Services

Every Type of Boiler Problem

Our service covers all common boiler issues that Swansea homeowners face. Pilot light problems, thermostat malfunctions, pressure issues, strange noises, uneven heating, and complete system failures. Both gas and oil boiler systems.

We handle everything from simple component replacements to complex repairs involving heat exchangers, pumps, and control systems. We work on all major boiler brands and carry common replacement parts on our trucks for faster repairs.

Emergency service is available during heating season when you can’t wait for regular business hours. We understand that a broken boiler in January isn’t something you can put off until next week. Quick response times help prevent pipes from freezing and keep your family comfortable.

Emergency boiler repairs get priority scheduling, especially during cold weather when heating is critical. Response times depend on the current service load and weather conditions, but we prioritize calls where customers have no heat. During extreme cold snaps, we extend service hours to handle more emergency calls. When you call for emergency service, we’ll give you a realistic timeframe and keep you updated if anything changes.
The most frequent issues include pilot light problems, thermostat malfunctions, and low water pressure. Older boilers often have issues with pumps and zone valves, while newer systems typically have problems with sensors and electronic controls. During winter, frozen pipes can cause pressure problems. Sediment buildup is common in areas with hard water, and annual maintenance helps prevent many of these issues from becoming major repairs.
Age is a major factor – boilers over 15 years old with frequent breakdowns often make more sense to replace. However, many repair issues are straightforward fixes even on older systems. Signs you might need replacement include consistently high energy bills, uneven heating throughout the house, frequent repairs, or major component failures like cracked heat exchangers. We’ll assess your specific situation and give honest recommendations about repair versus replacement costs.
Yes, you get a clear estimate before any repair work begins. We diagnose the problem first, explain what’s wrong, and provide upfront pricing for the repair. No work starts until you approve the estimate. This prevents surprise bills and lets you make informed decisions about the repair. If additional problems are discovered during the work, we’ll discuss those with you before proceeding.
We work on most residential boiler systems, including gas and oil units from major manufacturers. This includes both older cast iron boilers and modern high-efficiency condensing units. We handle steam and hot water systems, as well as combination boiler units. If your boiler is an unusual brand or very old model, we’ll let you know upfront about parts availability and repair feasibility.
First, check your thermostat settings and circuit breakers – sometimes the fix is simple. Look for error codes on newer boilers and check if the pilot light is lit on older units. If these basic checks don’t solve the problem, call for service rather than attempting complex troubleshooting yourself. Turn off the boiler if you smell gas or notice water leaks. During freezing weather, keep faucets dripping slightly to prevent pipe damage while waiting for repair service.
