*In Construction* Special Ops Project Gonell.

Updated by Senior Technician Agent C and Double 0.

Operation Gonell is now in Mechanical Operation. Our team is camped on the North-West corner of Bloor St W & Royal York Rd, Etobicoke. You might have seen our black and white Ford Transit vans parked outside. You might have seen us sippin’ on espressos or checking out your english bulldog.

Operation Gonell is the most exciting current renovation to happen in this neighborhood, straight up. The local, ambitious, and talented builder/remodeler Will Gonell, makes his centre stage debut back into the Kingsway area. Spending four years away in other Toronto neighborhoods – building highly detailed custom homes – he comes back with a National Award under his belt and a fresh insight into how your home can be built.

HVAC & Mechanical Scope

Update 1: October 30th, 2017.

Today we’ve started to “rough-in” a future radiant floor warming system. The process begins once your gravel base is raked level and waterproofing is done. It consists of installing special insulation atop the gravel, and then piping on top of the insulation. We call the insulation “PEX Panels” because they come in 2×4′ sheets and have round “pucks” where your PEX piping gets pressed between. They click together to form a solid layer or “insulation system” before you pour the concrete. We will then install a system of tubing that will carry hot water for heating.

The height of these PEX panels is greater than the standard styrofoam sheet your uncle layed in his basement and you had to help him on that one Saturday. You really didn’t want to do it because you had a party in Brock the night before, but cutting off the tips of 800 zip ties made it all worth it. The reasons to go with a 3.75″ tall panel are simple: 1. When radiant heating is your primary source of heat, the basement slab must have a minimum R10 insulation rating. 2. After switching to this method of pressing the PEX inside the “pucks” and not zip-tying on top, it greatly reduced the amount of punctures we had during the concrete pouring process.

Your basement gravel base will never be perfectly clear of all pipes from drains, radon systems, or weeping tile. We carry rakes, shovels, and a meticulous eye for dangers. Most of these can be worked around, then any small gaps and cracks are filled with foam.

October 31st, 2017 Update – Happy Haloween!

Today was a victorious day because of the innovative materials and pro technique that were meistered by both senior technicians on site. Damn Son! Let me explain…

If we want you to stay on this blog then you need to know how a hydronic radiant heating loop works. The embedded tubing will be the highway in which water will flow underneath the entire concrete slab. When using 1/2″ tubing (standard) you’re only allowed a certain length before pressure will be lost and won’t return back. Stagnant water like your son’s stinky socks he leaves behind is no good here ok??

floor heating loops

What to do when you reached your maximum limit but still have more basement to cover? You end up with loops. A total of six loops in this basement connect to a manifold/collector, or distribution centre. You now understand that water needs to supply and return from loops going into something called a manifold. Brilliant! You’re a Grade A genius now, *in a Jeremy Clarkson voice* Quick, go tell your mom before you forget. Then come back and keep reading.


True Story: On Orest’s day first day back from his 2017 Euro Tour Pt.2, he invited Agent C to The Yellow Cup Cafe in Etobicoke. Whilst eating their delicious sandwiches and having secret conversations, a German home renovation magazine finds itself onto the table. Orest goes on about how a reverse return loop layout should be the only way to go when installing floor heating. I kid you not. They both agreed – and the rule became from now on – to install reverse return heating loops every time!

Here is the page from the article. Notice where the arrow is pointing. Normally you would run your loops up and down the room until you’re done. FALSCH! You could do better.

germanmagA reverse return layout method distributes the heat evenly across the slab. It achieves more comfort, and it looks hot like your ____? All the European heating instagramers do it this way and girls seem to like my style. This is one step towards building better Mechanical Rooms and gaining higher performance. So lets go buy some PEX, plan some loops, get layed, and have a party!

Orest Oh

We Love Our Vans


The ability to carry tools and parts inside of our vehicles increases the confidence of our team and improves the chances of getting sh*t done. Speaking for many trades: electrician, painter, carpenter, builder, etc, they maintain a lifestyle of self-reliance and express it through working tools including vans. We’ve left this article to have open commentary so leave your opinion with a reply. This article begins with a short story, followed by pictures of our Transit XLT and ends with a video filmed somewhere in Ontario.

Shelving, partition wall, roof rack, winter tires, and a back-up camera will make you safe on the road but won’t fix the situation you’ve been sent out to diagnose. “The days of seeing a plumber with his ass crack showing are over”, says Will Gonell of Gonell Homes. Meaning, if you want to be involved with modern construction you need to be up to date and carry everything you could need that day. Clients have expected professionalism since forever, lets deliver on this.

At Blackrock HVAC we accept this reality so we work on improving the comfort, fun, and functionality of our vans. Our company culture has lots to do with automobiles and engines. If your van or truck is a tool for business then taking care of it is money well spent. Don’t be that guy who drives that creepy van around town scaring all the children, we’re trades professionals after all.

Basement Floor Heating.

Basement Floor Heating.

Radiant heating using a combination tank water heater for domestic hot water, and heating of a 500sq.ft basement floor. A forced air duct system provides heating and cooling for this semi-detached in the Bloor & Ossington area.

Underpinning Your Basement In Toronto?

This blog is designed to show you the process of building a modern radiant floor heating system in Toronto. We’ve make it simple so anybody can follow along. This is not a DIY but rather a helpful tool to organize and plan your renovation. Feel free to contact us at any time with your specific questions 🙂

Part 1: Rough In.

Part 2: Radiant Wall Assembly.

Part 3: Forced Air System (coming soon).

Part 4: Video Feature  (coming soon).


Part 1 – Rough In

When anybody at Blackrock HVAC talks about roughing in radiant heating, the following materials are being installed: R6 or R10 insulation, 1/2″ Radiant PEX, heating manifold, and slab sensor. In this basement we used 1.5″ R6 insulation with steel wire mesh, but have since moved on to a modern “Puck Style” R10 insulation. R10 is required by code when floor heating is your “Primary Heating Source”. Since most of your home’s heat loss comes from the basement slab it’s a no brainer that bigger is better.



There are two things to consider when choosing which insulation panel to go with, price and height. Going traditional with wire mesh may seem cost effective at first, but taking into account the insulation, tuck taping it together, mesh, and then zip tying everything together…it equates to the same amount. It’s wiser to go with “Puck Style” because it has a higher R-Value and installs much faster for the same price. It’s IMPERATIVE that you have a discussion with your underpinning crew about going with “Puck Style” because they always have a larger height! Your crew will have to go deeper to accommodate these extra couple inches (no pun intended). The concrete slab must be 3″ thick above the insulation for it not to crack.


Here you see the radiant rough-in complete and concrete cured. Since this is a Blackrock Bespoke Project we went ahead and painted the floor to mark the mechanical room territory, and per tradition hung solid oak to be our radiant wall and focal point (optional). Our next step is to put the combo water tank and furnace in place to visualize their connections to piping and duct work. DSC_0391


Step 2: Radiant Wall Assembly.

Don’t let the following pictures of unknown parts intimidate you! So lets break it down. Your floor heating system needs a few key components to make it work… we need a heat source, a circulator to move the heat in the piping, and a distribution system like a manifold that distributes heat through your PEX loops. Along the way we’ve installed a pressure/temperature gauge to monitor the performance, and a water back-flow preventer so your heating water never touches the domestic water. All these components can be mounted in a functional yet aesthetic way.

My Experience as a First Year HVAC Apprentice.

Lots of people tend to believe that after graduating college it is easy to find a job, regardless of the amount of experience you have. However, in reality, even once you graduate college, having field practice is VERY beneficial. In this article, a graduate from the George Brown College will share his first experience in the field as an HVAC Technician.

Furnace + Hot Water Tank.

Furnace + Hot Water Tank.

Like most mechanical rooms it was dark, creepy, and featured equipment that we turn a blind eye to.

Luckily these homeowners of this 1950’s Toronto bungalow planned ahead and were willing to build something exciting! Furnace, Water Tank, and Central Vacuum replacement.


With new equipment and cabinetry we’ve added swag to the entire 700 sq.ft basement.


Planning ahead nets better decisions. Here we decided to incorporate the furnace room into the basement – which was exposed – to create an Open Concept Mechanical Room. By replacing the HVAC appliances, using high quality workmanship and interior design, we had a modern plan that was going to impress visitors.




The first step was to empty the room leaving behind only ducts and water lines. An accent wall was built behind the future appliances to make a boring furnace room look more desirable and unique. Canadian red oak was chosen for the wall spanning 8’ in length.


Goodman is the largest manufacturer of HVAC products in North America. Their core values are reliability, easy serviceability, and industry leading warranty. It was a no brainer to go with a Goodman GMVM96 with 2-stage gas valve, variable speed fan motor, and an oversized 5” media filter.


The accent wall is illuminated with LED’s to give it the wow factor. New metal for the return drop gets rid of old dust. Venting, wires and gas lines were carefully joined and tucked away neatly to eliminate clutter. A 50 gallon water tank was chosen for its reliability and peace of mind for the next eighteen years.

Switches with stainless steel covers compliment the mechanical room, making it truly feel modern.

A Blackrock optional granite equiptment pad Serial #007 was placed underneath the furnace like a boss.

Once all the equipment was tested and the gaps in metal were siliconed, the floor received two coats of paint, the results were amazing. Black & Decker cabinets made their way for additional storage that was impossible to envision before.

Benjamin-Moore paint was used on the walls to give the room style.

Central Vacuum was updated by The Vac Man, Toronto’s Central Vacuum Specialist. This home now sports a Nilfisk unit with an Italian motor and some carbon fiber swag.


No Blackrock HVAC installation would feel authentic without some custom 3D printed functional items. In this mechanical room we had Rapitaro Designs print us a exhaust vent bracket with a gold leafed embossed logo.

We’ve come full circle since the 1950’s.

What you’re looking at now is the new norm: a functional, reliable, organized room for your renovated home. Creative customers let us challenge ourselves and at the same time push residential HVAC design forward.

Thank you for you interest in Blackrock HVAC.
