How long does a heat pump installation take in a New Westminster house?

For most New Westminster houses, a straightforward ductless mini-split installation wraps up in one day, typically six to eight hours. A ducted central heat pump on existing ductwork usually takes one to two days, and a more involved job with electrical upgrades, new ductwork or a multi-zone system can stretch to three or four days.

What Shapes the Timeline

The single biggest variable is your electrical panel. Many New Westminster homes from the 1960s through 1980s still have 100-amp service, and if the panel needs an upgrade to 200 amps before the heat pump circuit can be added, that work adds at least a half-day and coordinates a separate Technical Safety BC electrical inspection. The contractor pulls both the heat pump circuit permit and, if a gas furnace is being removed or its gas line capped, a gas permit, both through Technical Safety BC for New Westminster. Inspections are usually booked within a day or two of the rough-in, but scheduling can add time in busy seasons.

Other factors that stretch the job: a finished basement where the line set has to be routed through walls rather than an open utility space; a tight or sloped lot where the outdoor unit pad placement takes planning; a strata or shared-wall situation that needs extra care around penetrations; and removing old equipment like a boiler or electric baseboard system that requires disconnection and disposal.

A multi-zone system with three or four indoor heads in different rooms involves more line set runs, more wall penetrations and more commissioning time at the end, so two full days is realistic and three is not unusual.

The refrigerant commissioning and leak check at the end of the job cannot be rushed. Only a person approved under BC's Ozone Depleting Substances and Other Halocarbons Regulation may handle refrigerant, and that final pressure test and charge is what determines whether the system runs correctly from day one.

What a proper installation includes, and what you should confirm is in the quote: a heat loss calculation to size the unit correctly, the outdoor unit on a raised pad with clear drainage (important in New Westminster's wet winters), all line set and electrical work, both permits through Technical Safety BC, removal of the old equipment and a commissioning run to confirm heating and cooling modes both work.

Ask the contractor before they start: how many technicians are coming, whether the permits are already applied for, and whether the electrical panel has been assessed. A crew of two moves significantly faster than one person working alone, which matters if you are without heat in October.

Spring and early summer book up fast as homeowners rush to add cooling before the first heat wave, so if you are planning a summer install, locking in a date in March or April is worth it.
