A short April checklist for Metro Vancouver homeowners covering boiler shutdown-or-standby decisions, water heater checks, and what a licensed gas fitter looks at this time of year.

Quick answer
In April, Metro Vancouver homeowners should check the boiler's pressure gauge, look for mineral staining or moisture around the water heater base, and note whether the heating system is cycling less as daytime temperatures climb. This is also a good month to book a spring maintenance visit before the busy shoulder-season booking window fills up, since gas fitters see a jump in April service calls once people notice issues that were masked by constant winter heating.

By April, most Metro Vancouver heating systems have been running steadily for four or five months. The furnace or boiler has cycled thousands of times, the water heater has been working through winter's higher demand for laundry and longer showers, and any small issue that was easy to ignore in January often becomes obvious once the system slows down. Warmer days mean the boiler fires less often, so leaks, odd noises, or pressure changes that used to hide inside constant operation stand out more.
This is also the point in the year when a lot of homeowners start thinking about their hot water tank instead of their heating, because with the furnace running less, the tank becomes the main gas appliance doing daily work.
None of these checks require opening a gas valve or touching wiring. If anything looks off, the safest next step is describing it to a licensed technician rather than guessing at a fix.
Most of Metro Vancouver draws from a soft, low-mineral reservoir supply, which is generally easier on tank-style water heaters than the harder well water common out in parts of the Fraser Valley. Soft water slows the pace of scale buildup inside a tank, but it does not stop it, and April is a reasonable time to have sediment checked, particularly on a tank that has never been flushed. A tank running with a heavy layer of sediment at the bottom works harder to heat the same volume of water and is more prone to popping or rumbling noises.
Some Metro Vancouver homes use a boiler purely for space heating with a separate gas water heater, while others run a combi boiler or an indirect tank off the boiler for domestic hot water. If your boiler only heats the house, April is when many homeowners start asking whether to shut it down for the season. If it also makes your hot water, it needs to keep running year-round, just at a lower duty cycle. Knowing which setup you have changes the right April decision, and a technician can confirm this quickly if you are not sure.
April sits before the busiest part of the spring booking calendar, which tends to fill up once the weather turns reliably warm and people finally get around to service they put off all winter. A spring visit typically covers a general inspection of the burner and heat exchanger area, a check of venting and combustion air, a look at water heater sediment and the anode rod's general condition, and confirmation that safety controls respond correctly. This is a good time to flag any winter symptoms, even minor ones, so they can be looked at before next fall's heating season starts.
Safety note
If you ever smell gas, hear hissing near a gas line, or suspect a flue is spilling exhaust into the house, leave the home first and call FortisBC at 1-800-663-9911 from outside. Do not try to relight a pilot or reset a lockout yourself if you smell gas. Any work on gas piping, venting, or combustion components must be done by a Technical Safety BC licensed gas fitter.
It depends on your setup. If the boiler only provides space heating and you have a separate gas water heater, it is reasonable to let it sit idle over summer. If it also supplies domestic hot water through a combi unit or indirect tank, it needs to stay running year-round.
Lower background heat in the house can make cycling sounds, expansion ticking, or sediment-related rumbling more noticeable simply because there is less constant operation masking them, not necessarily because anything got worse.
Yes, spring is a practical window since the tank has had a full winter of use and any sediment buildup will be at its most established, making a flush more worthwhile before summer demand patterns settle in.
A hydronic system that repeatedly loses pressure between checks usually has a slow leak somewhere in the piping, a fitting, or an expansion tank issue, and should be diagnosed by a licensed technician rather than just topped up repeatedly.
Routine maintenance and inspection generally does not require a permit, but any replacement of gas piping, venting, or the appliance itself does, and your contractor should pull it as part of the job.
