Keep your cold chain and your building running
When a walk-in cooler warms up or an ice machine stops, product and sales are on the line. Tell us what’s happening and where, and we’ll call back quickly to arrange a technician, a maintenance visit or an installation quote.
We service the refrigeration that restaurants, grocery and convenience stores, cafés and hotels rely on every day, from walk-ins and reach-ins to display and deli cases and ice machines, plus rooftop units, commercial heating and cooling, gas-fired equipment and building mechanical systems.
Every job starts with a diagnosis on site and an upfront quote, so you approve the price before any work starts. Repairs come with a parts and labour warranty.
Walk-In Cooler & Freezer Repair
A walk-in that won’t hold temperature puts a whole day’s stock at risk. Most failures come down to the condensing unit, the evaporator and its fans, the defrost system, the controls or the box itself: doors, gaskets and heater wires that let warm, humid air in.

Problems we fix most
- Box temperature climbing or not pulling down
- Ice building up on the evaporator coil
- Water leaking from the evaporator or drain line
- Door not closing, torn gaskets or frost around the frame
- Condensing unit short-cycling or not starting
- Noisy evaporator fans or compressor
Before you call
Check that the door closes fully, that the evaporator fans inside are running and that the condensing unit on the roof or outside isn’t blocked. Note the box temperature and when it started rising.
How a walk-in is diagnosed
The technician checks the condensing unit and refrigerant pressures, the evaporator coil and fans, the defrost heaters, timer and controls, and the door gaskets and heaters, then gives you a quote before starting the repair.
Reach-In, Prep Table & Display Case Repair
Reach-ins and prep tables run hard in hot kitchens, so dirty condenser coils, failing fans and worn door gaskets are the usual culprits. Display, deli and meat cases add their own defrost and airflow problems, and a case that runs warm can mean throwing out product.

Problems we fix most
- Unit running warm or not holding temperature
- Product freezing in a cooler
- Frost on the evaporator or ice in the drain pan
- Water under or around the unit
- Condenser fan or compressor not running
- Door gaskets torn or doors not sealing
Quick check
Clean the condenser coil (on most reach-ins it sits behind the front grille), keep product away from the fan and air vents, and make sure the doors close on their own.
How a reach-in or display case is diagnosed
The technician checks airflow and the condenser, the fans, the defrost system, the controls and the refrigerant side before quoting the repair.
Commercial Ice Machine Repair & Cleaning
Ice machines fail in predictable ways: scale on the evaporator, a clogged water filter or valve, a harvest problem or a failing sensor. Regular cleaning and descaling prevents most breakdowns and keeps the ice safe to serve.

Problems we fix most
- Little or no ice
- Thin, cloudy or misshapen cubes
- Machine freezing up
- Water leaking from the machine or bin
- Error lights or harvest problems
- Heavy scale build-up
Brands
Hoshizaki, Manitowoc, Ice-O-Matic and other major commercial brands.
How an ice machine is diagnosed
The technician checks the water supply and filter, the water pump and valves, the harvest system and sensors, and the refrigeration side, then quotes the repair or a cleaning.
Commercial HVAC & Rooftop Unit Service
Rooftop units and commercial heating and cooling keep dining rooms, stores and offices comfortable, and a breakdown in July or January can close the doors. We service rooftop units and building mechanical systems, from no-cooling and no-heat calls to belts, motors, controls and seasonal maintenance.

Problems we fix most
- No cooling or weak airflow
- No heat from a rooftop unit
- Unit tripping or short-cycling
- Noisy fans, motors or belts
- Thermostat or controls not responding
- Water leaking from the unit
Seasonal maintenance
A check-up before summer and before winter catches worn belts, dirty coils and failing parts before they shut you down.
How a rooftop unit is diagnosed
The technician checks power and controls, airflow, belts and motors, the cooling circuit and the heating section, then quotes the repair before starting.
Gas-Fired Equipment Service
Gas-fired heating units and other gas-operated equipment need the ignition, burners, controls and venting working together. We service ignition and flame sensing, burners, gas valves and controls, and check the equipment before putting it back in service. If you ever smell gas, leave the building and call your gas utility’s emergency line first.

Problems we fix most
- Burner won’t light or stay lit
- Ignition or pilot problems
- Weak or uneven heat
- Unit locking out
- Noisy burner or flame problems
Maintenance
Yearly service keeps burners clean and catches worn ignition parts before the heating season.
How gas-fired equipment is diagnosed
The technician checks the gas supply to the unit, the ignition sequence and flame sensing, the burners, gas valve, controls and venting before quoting the repair.
Maintenance Plans & Installation
Most commercial breakdowns start as dirty coils, worn gaskets, clogged drains or tired fan motors. A preventive maintenance plan catches them on a schedule that suits your business, at one location or many. When equipment reaches the end of its life, we install new walk-in coolers and freezers, display and meat cases, and rooftop units.

What a maintenance visit covers
- Condenser and evaporator coils cleaned
- Temperatures, pressures and controls checked
- Fans, motors and belts inspected
- Door gaskets, hinges and heaters checked
- Drain lines cleared
- Ice machines cleaned, descaled and sanitized
Multi-location businesses
Restaurant chains, franchises and hotels can schedule maintenance across several locations with one point of contact.
Installation
New walk-in coolers and freezers, display and meat cases and rooftop units, sized for your space and load, installed and started up. Ask for a quote with your dimensions and the equipment you need.
