Cooling & Air Quality Services in Nanaimo & Vancouver Island
P3 Mechanical & Electrical installs and services air conditioning, ventilation, and indoor air quality equipment for homes and businesses in Nanaimo and across central Vancouver Island. Most residential work here is a single visit — a ductless air conditioner, an HRV, a range hood, a duct or dryer vent cleaning — while a whole-home ducting project takes several days. Either way the estimate is free, and the price comes from a written quote after we have seen the building rather than from a guess over the phone.
Cooling and air quality on Vancouver Island
Cooling used to be an afterthought on the east side of Vancouver Island. It isn't one any more: summers have turned hotter and drier, and the weeks that bring the heat now bring wildfire smoke over from the mainland and the Interior. That pairing is why cooling and air quality sit on one page — the afternoon you want the house shut up and cooled is usually the afternoon you want the air coming in filtered.
The other half of the year is the opposite problem. Mild, wet winters mean a house sealed against the rain also holds the moisture the people inside generate: condensation on windows, mildew along a north wall, a bathroom that never quite dries out. Homes built to current BC Building Code airtightness cannot rely on drafts for fresh air — they need mechanical ventilation, normally a heat recovery ventilator, with bath fans and a range hood ducted outdoors rather than into an attic. Older houses need the reverse: an exhaust path where nobody built one.
We work both sides: air conditioners and air handlers, ducted or ductless; HRVs, bath fans, range hoods, make-up air and dryer venting; and the filtration end of it, from media filters to UV lamps and dehumidifiers. The cooling equipment itself comes from Mitsubishi Electric, Daikin, Fujitsu, Carrier, Keeprite, Goodman, and Trane, picked per house rather than per supplier deal. Plenty of Island homes were built with no ductwork, so a ductless head is often the honest answer. Salt air off the Strait of Georgia is hard on outdoor coils, and strata councils have rules about where an outdoor unit and its lineset can go — both get settled before the quote, not on installation day. On commercial buildings the same crews handle rooftop units and kitchen make-up air; our commercial page covers that work.

Frequently asked questions
Do I actually need air conditioning on Vancouver Island?
More households here decide they do than used to. Summers now run hot enough that upstairs bedrooms stop cooling off overnight, and a home with a heat pump already cools as well as it heats. With no ductwork, one ductless head in the main living area is the usual start.
What can I do about wildfire smoke getting into the house?
Keep the windows shut and upgrade what the air passes through on the way in: a higher-efficiency filter in the furnace or air handler, a deeper filter cabinet where the slot is too shallow, or an HRV with a filtered intake. A portable HEPA unit cleans one room; ducted filtration treats the whole house whenever the fan runs.
Does a new home in BC have to have an HRV?
New homes in BC have to have mechanical ventilation, and a heat recovery ventilator is the usual way — it exhausts stale, humid air and draws fresh air in through a core that recovers most of the outgoing heat. Existing homes need not add one, though many do once condensation becomes a problem.
How much does it cost to add cooling to my house?
It depends mostly on whether the house already has ductwork: adding cooling to ducts that are there is the cheaper path, and a multi-head ductless system the dearer one. After that it is the number of rooms you want cooled and where the outdoor unit can sit. We do not publish figures for any of it — the visit is free, and the price comes in writing once someone has seen the house.
How long does a duct or dryer vent cleaning take, and is it worth doing?
Worth doing when there is a reason — a renovation, dust blowing out of the registers, or a dryer needing two cycles per load. A duct cleaning is normally an afternoon of work and a dryer vent less than that, and both are among the smaller jobs on this page. Cleaning on a fixed calendar with no symptoms is money spent out of habit.
