Most Common Condo System

Fan Coil
Units (FCU)

Fan coil units are the most common HVAC system in Toronto high-rise condos. They circulate air over a coil connected to your building's central chilled and hot water system — providing both heating and cooling from one compact unit. If your suite is too hot, too cold, or making noise, your fan coil is likely the culprit.

They're also the condo system we like best, because repairs are cheap. The parts that fail are small: an overflow switch runs about $120 plus labour, a three-way temperature switch about $120 plus labour, an actuator $250 to $300 plus labour, and a DC blower motor $500 to $800 plus labour. Most fan coil calls end with a part swap, not a replacement.

Common in Newer Condos

Water Source
Heat Pumps (WSHP)

Water source heat pumps are the condo call we get most. Unlike a fan coil, a WSHP makes its own heating and cooling by exchanging heat with the building's water loop, which means it has a compressor and refrigerant and more that can go wrong. We see them in every form: vertical stack units with a slide-in chassis, packaged water-source air handlers like the Carrier units, and ceiling-hung Daikin units above a hallway or closet.

We repair them and we replace them. On one chassis replacement, the new unit lost all its refrigerant three months in. We sent it back, the manufacturer confirmed a factory defect had caused the leak, and the customer got a brand-new chassis under warranty. That's the kind of thing you want your contractor to handle for you rather than argue about.

Discontinued Units

Skymark Unit
Retrofits & Replacements

Skymark HVAC units were once standard in thousands of Toronto condos — but the company is no longer in business and parts are no longer manufactured. This leaves condo owners in a difficult position: when a Skymark unit fails, most HVAC contractors can't fix it, and a full gut renovation to accommodate a different system is expensive and disruptive.

We specialize in Skymark retrofits — a cost-effective solution that replaces the internal mechanical components with modern, compatible equipment while keeping the existing cabinet in place. No drywall work, no building board headaches, no major renovation. Common Skymark failure points we address include failed compressors, worn fan motors, refrigerant leaks, broken controls, and complete unit failure. If your condo is too hot in summer or too cold in winter and you have a Skymark unit, call us before any other contractor tells you there's no solution. And if your unit is simply struggling to cool, it may just need a thorough cleaning before you consider any replacement.

★★★★★

“… every one of them only gave the option of doing an extremely costly replacement in the $13,000 to $16,000 range … Elham and Scott of Epsilon mechanical on the other hand were able to do a thorough on-site inspection … Their approach of maintainence vs. unecessary replacement saved me roughly 95% of the cost that the other companies quoted me”

“Our Johnson Controls (Skymark) HVAC unit stopped cooling, and another contractor suspected a coil leak and suggested costly repairs. … He and his team took the time to carefully inspect the system, performed a soap test, and confirmed there was no coil leak.”

“I had some cooling problems with my AC unit in a condo stacked townhouse. It was very hard to find a company that can deal with heights and condos. I was lucky to come across Elham’s company. Elham was able to fix the problem in a timely fashion.”

Which System
Do You Have?

Many Toronto condo owners don't know what type of HVAC system is in their suite. Here's how to identify yours — and what to do when it needs service.

01

Fan Coil Unit (FCU)

How to identify it: A cabinet unit usually located in a closet or along a wall. It has a fan and a coil but no compressor — it connects to the building's central hot and cold water pipes. You'll typically see two small water pipes running into the unit.

Common in: Older Toronto high-rises built before 2000. Very common in downtown condos.

View Fan Coil Services →
02

Water Source Heat Pump (WSHP)

How to identify it: Similar cabinet size to a fan coil but it has its own compressor — you'll hear it cycle on and off. It also connects to the building's water loop but generates its own heating and cooling rather than relying on the building's central system.

Common in: Newer Toronto condos and mid-rise buildings built after 2000.

View Heat Pump Services →
03

Skymark Unit (Discontinued)

How to identify it: Look for the "Skymark" brand name on the unit label. It's typically a floor-standing or closet-mounted unit. If a technician has told you parts aren't available or the unit can't be fixed, it's likely a Skymark.

Common in: Toronto condos built in the 1980s and 1990s. The brand is discontinued but the units are still widespread.

View Skymark Retrofit Services →
04

PTAC Unit (Self-Contained)

How to identify it: A large unit mounted under or beside a window, typically with a visible grille on the front. It's completely self-contained — no building water connections. Similar in appearance to a hotel room AC unit.

Common in: Older Toronto apartment buildings and condos, particularly those converted from apartments.

What a Condo Repair
Actually Costs

The diagnostic is $149 for any condo system, and it isn't cheaper than a house because it costs us the same to come: a truck, a technician, gas and the time to find the fault. It's non-refundable for the same reason. Once we know what's wrong, you get a price before any work starts, and the decision is yours.

We've worked for property management companies across the GTA on buildings full of fan coils and water source heat pumps, and we've seen just about everything a condo can have in its closet. If you're not sure what you've got, send a photo and we'll tell you.

How much does condo HVAC repair cost in Toronto?

Our diagnostic charge for any condo system is $149. That covers the truck, the technician and the time to find the problem, and it's the same as for a house because it costs us the same to come out. Repairs are quoted before any work starts. Fan coil parts are small: overflow and temperature switches around $120, actuators $250 to $300, a DC blower motor $500 to $800, each plus labour.

Do I need my condo board's approval to hire my own HVAC contractor?

Usually not. Most buildings only require that the contractor be licensed and insured. Many never check; some do, and when they ask we send our credentials and insurance certificate directly to management. We also handle elevator bookings and suite access if the building requires it.

Which condo HVAC system is cheaper to repair, a fan coil or a water source heat pump?

A fan coil, by a wide margin. It has no compressor and no refrigerant, so what fails is switches, actuators and the blower motor. A water source heat pump has a full refrigeration circuit, so repairs can involve refrigerant work or a chassis replacement, and cost more.

Do you repair and replace fan coil units in Toronto condos?

Yes. Fan coil units are the most common HVAC system in Toronto high-rises and we repair, service, and replace all makes and models, including filter cleaning, valve and actuator service, and full unit replacement.

Do you service water source heat pumps in Toronto condos?

Yes. Vertical stack units with a chassis, packaged water-source air handlers, and ceiling-hung units. We repair them, replace chassis and whole units, and deal with the manufacturer on warranty claims.

Can you replace or retrofit a Skymark unit in a Toronto condo?

Yes. Skymark units are discontinued, and we retrofit or replace them with compatible modern equipment that fits the existing cabinet, with no drywall work. The same goes for the older Singer and Fedders packaged units.

Do you service PTAC units in Toronto condos?

Yes. We service and replace PTAC units in older Toronto condos and residential buildings. We see them less often than fan coils and water source heat pumps, but we've worked on all of them.
