Independent service providers perform the work. Boiler Repair Pro helps connect consumers with providers and does not employ technicians.
Ask the accepting provider about diagnostic charges, parts, labor and any call-out fee. Review the proposed scope and price before authorizing work.
Ask the accepting provider directly. Availability and arrival times depend on the scope and schedule; this site does not guarantee same-day service.
Ask the independent provider for written parts and labor warranty terms before approving work. This website does not guarantee work outcomes.
If you smell gas, suspect combustion fumes, hear a carbon-monoxide alarm or notice fire or electrical burning, leave the area and contact the appropriate emergency service or utility before arranging routine repair.
Confirm provider qualifications, insurance and any required licensing, then review the diagnosis, proposed work, total price and payment terms.
Keep the findings, invoice, agreed warranty terms and any instructions for monitoring the system. Record the time and symptoms if the problem returns.
