## When the Dining Room Overheats at Dinner

Of all the 

commercial rooftop units we install in Toronto

[/ →](/)

, the 5-ton size is the most common over small restaurants and offices. The typical complaint sounds familiar: the dining room is comfortable at lunch and hits 28C by Friday dinner service, or a small office cannot hold setpoint on a hot afternoon.

A **5-ton RTU** delivers about **60,000 BTU** of cooling. Whether that is enough depends on more than floor area, especially in restaurants.

## Restaurant Load and Make-Up Air Interaction

Restaurants have two loads offices do not: the **kitchen heat load** from cooking equipment, and the **make-up air interaction** between the RTU and the make-up air unit (MUA) that replaces air pulled out by the hood.

-   If the MUA is off or undersized, the building goes negative. Doors get heavy, hoods backdraft, and hot outdoor air leaks in for the RTU to fight.
-   If the MUA supplies untempered air in summer, the RTU has to cool that air too.
-   Grease from the exhaust coats nearby condenser coils, cutting capacity.

That is why we size restaurant RTUs with the kitchen and MUA in the calculation, and why we often service both units together. See 

make-up air unit service

.

## Fit by Use

| Use | Why 5 tons often fits | Watch for |
| --- | --- | --- |
| Small restaurant or cafe | Dining room + kitchen spillover | Hood exhaust, MUA balance |
| Small office | Several thousand sq ft, typical occupancy | Glazing, server closet |
| Retail with high traffic | Door openings, lighting | West-facing windows |

If the load is lighter, a 

3-ton unit

[/3-ton-rooftop-unit-toronto/ →](/3-ton-rooftop-unit-toronto/)

 may fit. If it is heavier, see

## How Much Does a 5-Ton RTU Cost?

3-5 ton units run **$9,500-$16K installed** in **3-5 business days**, including crane, curb check, connections and commissioning. Common models include the **Carrier 50TC** and 5-ton units from Lennox, York, Trane and Daikin. An **economizer** is worth adding for offices; restaurants benefit less because of kitchen loads.

## Repair First, When It Makes Sense

Not every hot dining room needs a new unit. Our Liberty Village restaurant had a dead RTU and backdrafting hoods in July. A failed fan motor, a grease-coated coil and an MUA burner problem were fixed on one visit for **$1,840**. Restaurants get priority on our

## Liberty Village restaurant RTU + MUA repair

In July, a Liberty Village restaurant had a dead rooftop unit and backdrafting hoods. The RTU had a failed fan motor and a grease-coated coil; the make-up air unit had a burner and airflow problem leaving the kitchen negative. Both were fixed on one visit, with the tally written before work started.

### How much does a 5-ton rooftop unit cost installed in Toronto?

3-5 ton units run $9,500-$16K installed, including crane, curb check, connections and commissioning on standard roofs, typically in 3-5 business days.

### Is 5 tons right for my restaurant?

A 5-ton unit delivers about 60,000 BTU of cooling, which suits many small restaurants once kitchen heat and make-up air are counted. Larger dining rooms or heavy cooking lines may need more. We size with Manual J on site.

### Why does my dining room overheat during dinner service?

Usually the unit is undersized for the combined load of guests, cooking heat and outdoor air, or the make-up air unit is pushing hot untempered air. Sometimes it is a dirty, grease-coated coil. We check all three.

### How does make-up air affect my rooftop unit?

Kitchen hoods exhaust large volumes of air. The make-up air unit replaces it. If the MUA is undersized or off, the building goes negative and the RTU fights infiltration; if it supplies hot air, the RTU has to cool it.

### Do you service the RTU and MUA together?

Yes. Our Liberty Village restaurant RTU + MUA repair came in at $1,840 on one visit.

### How often should a restaurant RTU be cleaned?

Restaurant roofs collect grease and debris fast, so coils need cleaning at least in spring and often mid-summer, and filters may need monthly changes.

### Is 5 tons right for a small office?

Often, for offices around a few thousand square feet with typical occupancy. Glazing, equipment and ventilation change the answer, so we size on site.

### Which 5-ton models do you install?

Common choices include the Carrier 50TC, Lennox, York, Trane and Daikin 5-ton packaged units. We price options side by side.
