## Common Carrier Rooftop Unit Problems

Carrier rooftop units sit on thousands of GTA plazas and office buildings. The calls we see most on **Carrier WeatherMaker** and **Carrier 50TC** units are failed condenser and indoor fan motors, **economizer** faults, short cycling from controls or charge problems, and, when units reach end of life, legacy footprints that no new unit fits without a **curb adapter**.

A fan motor that fails once is a repair. A fan motor that fails every summer has a cause: a weak capacitor, voltage imbalance, a dirty coil or water intrusion. We fix the cause along with the part.

## Carrier Models We Sell and Service

### Carrier WeatherMaker

One of the most common packaged commercial lines in Canada. Newer WeatherMaker units use the direct-drive **EcoBlue fan**, which drops belts and pulleys and needs controls know-how to diagnose.

### Carrier 50TC

A widely used packaged unit in the 3-12.5 ton range. We often install 50TC units as replacements on legacy Carrier curbs, with adapters from our shop.

### Carrier AquaForce chillers

Our CRE-ticketed crew services Carrier AquaForce air-cooled chillers. See 

commercial chiller service

[/commercial-chiller-service-toronto/ →](/commercial-chiller-service-toronto/)

.

## Carrier Replacement on Legacy Curbs

Carrier footprints have changed over the decades. Rather than cutting a new roof opening, we fabricate a curb adapter to fit the new unit onto the existing curb and re-flash it, usually as a one-day swap per unit. See 

commercial rooftop unit replacement

[/commercial-rooftop-unit-replacement-toronto/ →](/commercial-rooftop-unit-replacement-toronto/)

.

## Carrier Pricing

| Work | Price | Timeline |
| --- | --- | --- |
| 3-5 ton Carrier RTU installed | $9,500-$16K | 3-5 days |
| 10 ton Carrier packaged | $18K-$34K | 5-7 days |
| 15-20 ton Carrier | $32K-$58K | 7-10 days |
| Economizer + controls diag | $450-$900 | Same day |

High-efficiency Carrier units often qualify for Save on Energy rebates of $200-$1,500 per ton, netted on your invoice.

## Why Use an Authorized Carrier Dealer?

**OEM parts** on the van mean fewer return trips, warranty claims are filed correctly, and replacements are sized and selected from current Carrier models. We cover Carrier plazas in 

Oakville

Client Records

## What Clients Say About Our Carrier RTUs

> "Our old Carrier units did not match any new curb. Their adapters made the swap a one-day job per unit with no roof work."

MTMarcus T.PM, Oakville retail plaza

> "Hydro on our Oakville retail building dropped after the first year of coil cleaning and economizer calibration. The reports helped us budget two replacements."

VLVictor L.Facility manager, Oakville

> "Breaker kept tripping on a 33C Saturday. They found a seized condenser fan motor, had one on the van and we were cooling by mid-afternoon."

TMTeresa M.Store manager, Markham

> "Our screw chiller kept tripping on oil loss. They found a failing oil separator and had the machine back in service in two days."

HYHassan Y.Plant manager, Mississauga

> "We get a written tally every time before any work starts. That alone made them our only rooftop contractor for three plazas on The Queensway."

CNChris N.Facility coordinator, Etobicoke

### Are you an authorized Carrier dealer in Toronto?

Yes. We are an authorized Carrier commercial dealer for rooftop units and packaged chillers, with OEM parts stocked.

### Which Carrier rooftop units do you service?

Carrier WeatherMaker and 50TC packaged units, older Carrier commercial lines where parts are available, and Carrier AquaForce chillers.

### What does a Carrier rooftop unit cost installed?

3-5 ton units run $9,500-$16K, 10 ton $18K-$34K and 15-20 ton $32K-$58K installed. Curb adapters for legacy footprints are priced on their own line.

### Why does my Carrier unit keep losing its fan motor?

Repeat fan motor failures usually point to a weak capacitor, voltage problems, a dirty coil running the motor hot or water getting into the motor. We fix the cause along with the motor.

### Can a new Carrier unit fit my old Carrier curb?

Often not exactly. Legacy Carrier footprints changed over the years, so we fabricate a curb adapter in our shop to fit the new unit to the existing opening without roof work.

### What is the Carrier EcoBlue fan?

EcoBlue is Carrier's direct-drive indoor fan design on newer WeatherMaker units. It removes belts and pulleys and can cut fan energy, but needs a tech who knows its controls.

### Do Carrier units qualify for Save on Energy?

High-efficiency Carrier units often qualify at $200-$1,500 per ton. We file the pre-approval before ordering.

### Do you repair Carrier economizers?

Yes. Economizer and controls diagnostics run $450-$900, covering actuators, sensors, dampers and changeover settings.
