Risk Disclosure

## Commercial Rooftop Unit Problems in Oakville Plazas

The local pattern

### Retrofit paperwork that stalls on a different utility account

**What you see:** The rebate filing for a plaza retrofit sits waiting while the landlord's other GTA sites went through without a hitch.

**Why it happens here:** Buildings in town are served by Oakville Hydro, not Alectra or Toronto Hydro, so account numbers, meter data and incentive contacts come from a different distributor than a portfolio's Mississauga or Toronto sites.

**What we do:** We collect the local utility account details at the site assessment and file the Save on Energy retrofit application before equipment is ordered.

01

### Wrong diagnosis

A residential tech misreads a commercial economizer and replaces parts that did not need it. We megger windings and test controls before anyone quotes a compressor.

02

### Wrong equipment match

A contractor quotes a 5-ton split when the roof needs a 10-ton packaged unit. Manual J/S sizing and a curb check come before the quote, not after the crane.

03

### Wrong rebate math

Nobody files Save on Energy and the PM leaves $8K-$30K on the table. We lock the pre-approval before equipment is ordered and net it on the invoice.

How it works

## Five Steps From Roof Walk to Sign-Off

Five steps, the same on every job, from a single compressor to a multi-unit program.

1.  01
    
    ### Site assessment
    
    A Red Seal lead walks the roof, reads nameplates, checks curbs, access and electrical, and logs every symptom.
    
2.  02
    
    ### 24-hr written quote
    
    Parts, labour, crane, permit and HST on one line, plus the repair-vs-replace math when the unit is old.
    
3.  03
    
    ### Rebate pre-approval
    
    We file Save on Energy or Enbridge paperwork before equipment is ordered, so the rebate is locked in.
    
4.  04
    
    ### Install / repair
    
    WSIB crews, crane day and street-occupancy permits handled. Tenants get a schedule, not a surprise.
    
5.  05
    
    ### Commissioning sign-off
    
    Startup readings, controls check and a commissioning report you can file. Final 25% only after sign-off.
    

Standard 5-10 ton RTU: 3-5 business days from quote to startup.

Local logistics

## West-GTA Dispatch Down the QEW

The town gets **same-day scheduled visits** and **

emergency dispatch

[/emergency-rooftop-unit-repair-toronto/ →](/emergency-rooftop-unit-repair-toronto/)

 from the GTA core** via the **QEW** and the **403**. Crews reach the **Uptown Core** and **Winston Park** from the 403 and Trafalgar, the **QEW corridor** offices and **Oakville Place** from the QEW, and the old downtown and **Bronte** from Lakeshore Rd.

The QEW westbound in the evening is slow, so emergency arrival windows are confirmed by dispatch when you call. Contract sites get priority and pre-staged parts so repairs finish faster. Most plaza and office roofs have parking-lot crane access, which keeps lift days simple.

Seasons on these roofs

## Seasonal Notes for Plaza Contracts

Restaurants and street-front retail along Lakeshore Rd in Bronte and the old downtown carry heavy latent load on humid summer days, so coil condition and airflow matter for comfort as much as temperature. Spring maintenance covers coil cleaning, belts and economizer calibration before June. Winter visits check heat exchangers and flame sensors on gas-fired

 before the January cold snaps.

### How quickly can you respond in Oakville?

Scheduled visits along the QEW corridor are usually booked for the same day. Emergency calls dispatch from the GTA core via the QEW and 403, and dispatch confirms a realistic arrival window for the Uptown Core, Winston Park or Bronte. Contract sites get priority.

### Does our utility change how the rebate application works?

The Save on Energy program is the same, but the paperwork is not. Buildings in town are served by Oakville Hydro, so account and meter details come from a different distributor than Mississauga or Toronto sites. We collect them at the site assessment so the filing does not stall.

### What does an RTU maintenance contract cost for a plaza in the Uptown Core?

$295-$450 per unit per year with quarterly inspections, or $240-$340 per unit for 12 or more units on one site. Pricing is locked for the term.

### Do you service Carrier WeatherMaker and 50TC units?

Yes. We are an authorized Carrier dealer for WeatherMaker and 50TC units and fabricate curb adapters in-house when legacy Carrier units on Trafalgar and Dundas plazas are replaced.

### Which parts of town do you cover?

The Uptown Core, QEW corridor, the old downtown, Winston Park and Bronte, plus the retail and office pockets along Trafalgar and Dundas.

### What does a commercial RTU repair cost?

The same as the rest of the GTA: diagnostics $275-$425 in business hours, refrigerant leak and recharge $850-$2,800, compressors $2,400-$5,600. You get a written tally before work starts.

### Can you replace an old RTU without hiring a roofer?

Usually, yes. We fabricate curb adapters in-house and handle re-flashing at the curb, so most replacements do not need a separate roofing contractor.
