Boiler Repair Process

Simple Process, Fast Results

When you call us about your boiler problem, we’ll ask a few quick questions to understand what’s happening. Is the system not heating at all? Making strange noises? Leaking water? This helps us bring the right tools and parts.

Our technician arrives with a fully stocked truck and runs a complete diagnostic check. We test the thermostat, examine the heat exchanger, check gas or oil connections, and inspect all safety controls. Most boiler problems have multiple possible causes, so we don’t guess.

Once we identify the issue, we explain what’s wrong and give you a clear repair estimate. No surprises, no pressure. If you approve the work, we handle the repair on the spot in most cases. We test everything thoroughly before we leave to make sure your heat is working properly.

How much does boiler repair typically cost in the Greenvale area?

Boiler repair costs vary depending on the specific problem and parts needed. Simple issues like thermostat replacement might cost $200-400, while more complex repairs involving circulation pumps or heat exchangers can range from $500-1500. We always provide upfront pricing before starting any work, so you know exactly what you’ll pay. There are no hidden fees or surprise charges. We also offer financing options for larger repairs and can help you determine if repair or replacement makes more financial sense for your situation.

Do you offer preventive maintenance to avoid future boiler breakdowns?

Yes, we provide comprehensive boiler maintenance programs designed to prevent emergency breakdowns and extend your system’s lifespan. Our annual maintenance includes thorough cleaning, safety inspections, efficiency testing, and component adjustments. We check all safety controls, clean burners, inspect heat exchangers, and test system pressures. Regular maintenance typically prevents 80% of common boiler problems and helps your system run more efficiently, saving money on heating bills. Many customers schedule maintenance in September or October, before the heating season begins.

What should I do if my boiler stops working during a winter storm?

First, check your thermostat settings and circuit breakers to rule out simple issues. If the boiler still won’t start, call us immediately for emergency service. We respond to heating emergencies even during severe weather conditions. While waiting for our technician, avoid trying to repair the system yourself, especially with gas boilers. Keep interior doors open to circulate any remaining warm air, and if you have a fireplace, use it safely for supplemental heat. Never use outdoor grills or camping equipment indoors for heating, as this creates dangerous carbon monoxide risks.

How long do boiler repairs usually take to complete?

Most boiler repairs are completed the same day, typically within 2-4 hours depending on the complexity of the problem. Simple fixes like thermostat replacement or minor adjustments often take less than an hour. More involved repairs requiring component replacement might take 3-4 hours. In rare cases where we need to order specialty parts, we’ll provide temporary solutions to keep you warm while waiting for parts to arrive. Our technicians carry extensive parts inventory, so we can complete most repairs immediately without return visits.
