Maintenance here is a checklist with numbers on it, not a sticker on the panel. Each visit records temperatures, pressures, amp draws, wash and rinse temperatures and condenser condition, so you can see equipment drifting before it fails during a Friday dinner rush.

What we repair — and how we find it

Refrigeration inspection

Condenser and evaporator cleaning, charge verification, defrost check, drain flush, gasket and door hardware review.

Cooking equipment

Ignition and flame sense, thermostat and probe calibration, gas pressure checks, fan and door hardware.

Warewashing

Wash and rinse temperatures, booster operation, chemical feed, spray arms, scale management.

HVAC and rooftop units

Filters, belts, coil cleaning, amp draws, refrigerant pressures and condensate management.

Ice machines

De-liming, sanitization, water filtration and production rate verification.

Reporting

A written visit report with measurements, corrective items and priorities you can budget against.

Commercial Appliance Maintenance — questions we get asked

What is included in a maintenance visit?
Cleaning and inspection of the equipment on your inventory list, recorded temperatures, pressures and amp draws, small adjustments on the spot, and a written report with prioritized corrective items.
How often should we schedule?
Quarterly for kitchens with fryers, char-broilers or heavy grease load; semi-annual for retail and office equipment. We recommend an interval after the first site walk.
Do maintenance customers get faster repair response?
Yes. Maintenance accounts get priority commercial scheduling in the Maryland / DC metro, and we already know your equipment and its history.
Is maintenance priced per visit or per year?
Both work. We quote after a site walk based on equipment count and interval — call 443-295-4865 for pricing.
Do you cover HVAC as well as appliances?
Yes — packaged rooftop units, split systems and mini-splits alongside refrigeration and kitchen equipment.
