Heating systems often give warning signs before they fail completely. Catch problems early to avoid a cold house and an emergency repair bill:
- Banging, knocking, or whistling noises from the boiler or pipes (often caused by scale buildup or low flow)
- Uneven heating — some rooms warm, others cold — indicating a zone valve or balancing issue
- Boiler pressure gauge frequently in the red zone or pressure relief valve dripping
- Yellow or orange pilot flame instead of blue (indicates incomplete combustion — a safety concern)
- Heating system cycling on and off more frequently than usual
- Higher gas bills without a change in usage pattern
- Radiators that stay cold even after bleeding
High-Efficiency Boiler Upgrades and FortisBC Rebates
Replacing an aging boiler with a modern high-efficiency condensing unit can cut your heating bills by 20 to 30 percent. Many installations qualify for FortisBC rebates of up to $1,000. We handle the rebate paperwork and can walk you through the available models, payback periods, and financing options before you commit to anything. Our goal is to match you with the right system for your home and your budget — not the most expensive one.
Available 24/7 for No-Heat Emergencies
Heating Issues We Resolve
Boiler Won't Fire
A pilot outage, failed igniter, or gas valve problem can shut down your entire heating system. We diagnose and repair on the same visit.
Uneven Heat Distribution
Cold spots in a hydronic system usually mean air locks or a failing zone valve. We bleed the system and replace faulty components.
Boiler Leaking
Pressure relief valve discharging or corrosion leaks can damage your home. We identify the source and repair before it escalates.
High Heating Bills
An inefficient boiler can waste 20-30% more gas. We tune the combustion, clean the heat exchanger, and restore peak efficiency.
No-heat calls are dispatched around the clock, including evenings, weekends, and statutory holidays. Our technicians carry the most common boiler parts and ignition components on their trucks so that most emergency repairs are completed in a single visit. We serve Vancouver, Burnaby, Richmond, Surrey, New Westminster, North Vancouver, West Vancouver, Delta, Coquitlam, and Port Moody. Call (778) 239-9199 any time.
