Toronto Commercial HVAC

[/ →](/)

 repairs low-temp walk-in freezers for restaurants, grocery stores, ice cream shops, caterers, hotels and frozen food distributors across Toronto and the GTA. Freezer calls get 24-hour priority routing on our food-service line, and every repair is done by 313A licensed mechanics.

Freezers fail harder than coolers. They run at -18C to -23C, so defrost has to work every cycle or the evaporator ices over. Drain lines need heat tape or defrost water refreezes. Door heaters keep doors from freezing shut. Low-temp compressors work harder and run hotter. When any one of these fails, the box warms, product starts to soften and the clock starts. One hour of walk-in freezer failure can mean $8K in lost product.

Freezer repairs typically cost $650 to $4,500, plus a $225 diagnostic. Low-temp compressor rebuilds top out around $4,500, and we monitor the 4-6 hour thermal recovery after every repair.

## What Does Walk-In Freezer Repair Cover?

### Defrost system

Electric defrost heaters, defrost timers, termination switches and hot gas defrost valves.

### Drain system

Drain pans, drain line heat tape and frozen drain clearing.

### Refrigeration circuit

Low-temp Copeland scroll and semi-hermetic compressors, condensing units, expansion valves and refrigerant leaks.

### Box and doors

Door heaters, gaskets, closers, pressure relief ports and panel damage.

## Freezer Problems and Typical Repairs

| Symptom | Likely cause | Typical range |
| --- | --- | --- |
| Coil iced solid | Failed defrost heater or timer | $650-$1,500 |
| Ice on floor or ceiling | Frozen drain or door leak | $650-$1,400 |
| Door freezing shut | Failed door heater | $650-$1,200 |
| Box warming slowly | Leak, dirty condenser, fan | $650-$2,500 |
| Compressor failed | Low-temp compressor | $2,500-$4,500 |

## What to Do When Your Freezer Fails

1.  Keep the door closed. A loaded freezer holds temperature longer than you think.
2.  Check and record product temperatures.
3.  Move high-value product to a working freezer if you can.
4.  Call our 24-hour line. If parts are needed, we help arrange a reefer.
5.  Do not chip ice off the coil with tools; it is easy to puncture tubes.

## Thermal Recovery

After the repair, a loaded freezer usually needs 4-6 hours to pull back to setpoint. We log box temperatures through recovery and leave the record for your food safety file. If recovery stalls, we find out why before we leave.

Why Us

## Why Choose Toronto Commercial HVAC for Walk-In Freezers?

### Low-Temp Specialists

Freezers run at -18C to -23C or colder. Low-temp compressors, defrost and drains need different know-how than coolers.

One hour of freezer downtime can mean $8K in lost product, so freezer calls go first.

### Recovery Monitoring

We do not leave when the compressor starts. We log temperatures through the 4-6 hour recovery.

### Reefer Coordination

When a repair needs parts, we help get a reefer trailer on site to protect product.

### Proven Program Results

Our Vaughan grocery freezer program averaged a 2:40 response with zero product loss in 2025.

### 313A Licensed Mechanics

All freezer work is done by licensed 313A mechanics with full refrigerant recovery and logging.

Straight Answers

## Walk-In Freezers FAQs

### How much does walk-in freezer repair cost in Toronto?

+

Walk-in freezer repair in Toronto typically costs $650 to $4,500, plus a $225 refrigeration diagnostic. Defrost and drain repairs such as defrost heaters, timers, termination switches, drain line heat tape, fan motors and controllers usually run $650 to $1,800. Low-temp compressor replacement or rebuild and refrigerant leak repair with evacuation and recharge run $1,800 to $4,500. Refrigerant is billed by the pound and after-hours calls add a $185 surcharge. If product has to be moved while parts arrive, we arrange a reefer trailer at cost. Every repair includes temperature logging through the 4-6 hour recovery.

### Why is my walk-in freezer not freezing?

+

The most common causes are failed defrost heaters or timers that let the evaporator ice up, a frozen drain line, failed evaporator fans, a refrigerant leak, a dirty condenser or a failing low-temp compressor. Door heaters and gaskets also matter: a door that freezes open or does not seal lets warm air flood in.

### Why is there so much ice on my freezer coil?

+

Freezer evaporators rely on electric or hot gas defrost. When heaters, timers or termination switches fail, ice builds until airflow stops. Ice on the floor or ceiling usually points to a frozen drain line or a door that is not sealing.

### How long does a freezer take to recover after repair?

+

Thermal recovery usually takes 4-6 hours to bring a loaded walk-in freezer back to setpoint. We log temperatures through recovery and leave a written record.

### What should we do with product while the freezer is down?

+

Keep the door closed, as a loaded freezer holds temperature for a while. Check product temperatures, move high-value items to working freezers, and if the repair needs parts, we help arrange a reefer trailer.

### How fast can you respond to a freezer failure?

+

Freezer failures get top priority on our 24-hour line with a 2-4 hour emergency response across Toronto and the GTA.

### Do you repair blast freezers and ice cream freezers?

+

We repair low-temp walk-in freezers, including ice cream and frozen distributor boxes. Specialty blast freezers are assessed case by case.

### What is drain line heat tape?

+

A heater wrapped around the freezer drain line so defrost water does not refreeze on its way out. When it fails, ice backs up into the drain pan and onto the coil.

### Is there a warranty on freezer repairs?

+

Yes. A 90-day labour warranty, plus manufacturer parts warranties.

### How can we prevent freezer breakdowns?

+

Quarterly maintenance with condenser cleaning, defrost and drain heater checks, door heater and gasket checks and controller review. Our refrigeration maintenance programs cover all of these.
