## Rooftop Unit Trouble in Mississauga Parks? Here Is What Goes Wrong

The local pattern

### Crane day pushed back by an airport permit nobody filed

**What you see:** The replacement units are on order and the tenants have been told, then the lift date slips by weeks.

**Why it happens here:** Parks near Pearson can sit inside the airport's obstacle assessment area, where a crane needs land use approval from Pearson and NAV CANADA first, and that review can take 12 weeks or more.

**What we do:** On replacement programs we check the site against Pearson's crane rules at quote stage and file early, so the lift date in the schedule is one we can hold.

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

## From Site Walk to Startup, Step by Step

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

## Routes and Response Across the West GTA

The city sits inside our 2-4 hour GTA core response. Crews reach the **Airport Corporate Centre** and **Airport Rd corridor** from Highway 427 and the 401, **Meadowvale** from the 401 and Mavis, and the **City Centre** around Square One from the 403. The 401 / 403 / 410 interchange is the choke point at rush hour, so scheduled work is booked outside the 7-9am and 4-6pm windows whenever we can.

Industrial parks near **Toronto Pearson** have flat roofs with good crane access from parking lots, which keeps crane days shorter and cheaper than downtown. The catch is the airport: sites inside Pearson's obstacle assessment area need land use approval from Pearson and NAV CANADA before a crane permit is issued, and that review can take 12 weeks or more. A crane on a municipal road also needs a road occupancy permit. We check both at quote stage.

For multi-unit programs we phase lifts across consecutive days or weekends so the park keeps running. On Airport Rd, 14 units were swapped in 11 days without shutting the park down.

Seasons on these roofs

## Seasonal Notes for Big Flat Roofs

Big flat industrial roofs near the airport take full sun and wind, so condenser coils load up with dust and debris by mid-summer. We book spring coil cleaning and belt changes before May. In winter, warehouse gas heat and RTU heat sections carry the load; flame sensor and igniter failures on cold mornings are the most common call. Replacement programs are best planned in fall or late winter so Save on Energy pre-approval (4-8 weeks) lands before spring lifts.

Published GTA pricing

-   RTU diagnostic (business hr)$275-$425
-   3-5 ton RTU installed$9,500-$16K
-   10 ton packaged installed$18K-$34K
-   Annual RTU maintenance$295-$450/unit

### Do I need airport approval for a crane lift near Pearson?

Possibly. If the site sits inside Toronto Pearson's obstacle assessment area, the crane needs land use approval from Pearson and NAV CANADA before Pearson issues a crane operation permit. NAV CANADA's review can take 12 weeks or more, so we check this at quote stage.

### Can you replace a whole row of RTUs without shutting down the park?

Yes. We phase lifts over consecutive days or weekends, swap units one zone at a time and keep temporary cooling on standby. On Airport Rd all 14 units were replaced while the park kept running.

### How much does a 10-25 ton RTU replacement cost in Mississauga?

10 ton packaged units run $18K-$34K installed, 15-20 ton $32K-$58K, and 25 ton and larger $55K-$95K. Multi-tenant programs run $8,500-$14K per unit. Save on Energy can take $200-$1,500 per ton off qualifying retrofits.

### Does a crane on a city road need its own permit?

Yes. Lifts from private parking lots usually only need the property owner's approval, but a crane on a City of Mississauga road needs a road occupancy permit, which we file as part of the quote.

### Do you service Lennox Landmark and LCG units?

Yes. We are an authorized Lennox dealer with OEM parts stocked for Landmark, Energence and LCG units, the same equipment used on the Airport Rd program.

### What is the fastest emergency response in Meadowvale?

Meadowvale and the Airport Corporate Centre sit inside the GTA core: a 30-minute dispatch window and a tech on the roof in 2-4 hours, 24/7, via the 401 and 427.

### Do you offer maintenance contracts for multi-tenant industrial condos?

Yes. Annual RTU maintenance runs $295-$450 per unit per year, or $240-$340 per unit for 12+ units on one site, with quarterly inspections and a written report per unit.

### Can you help us budget for aging RTUs across a park?

Yes. A site assessment covers every unit's age, condition and refrigerant type, and you get a written replacement schedule with rebate-net pricing so capex can be planned over two or three years.

### Do you work on warehouse unit heaters as well as RTUs?

Yes. Our TSSA G1 and G2 techs service gas-fired unit heaters and RTU heat sections, which carry most of the winter load in logistics buildings near Pearson.
