Preventive Maintenance

One of the most important things in regards to your equipment is making sure that it stays running. We highly recommend preventive maintenance service to all equipment to ensure that it operates to its highest efficiency and that breakdowns are prevented.

Ice machines especially are the first thing that will fail a health inspection. Ask us about setting up regularly scheduled maintenance on your ice making equipment to make sure you are serving your customers the cleanest ice in town.

HVAC systems are constantly moving air so it’s easy for them to get clogged up with dirt and dust or pollen throughout the year. Setting up periodic or seasonal filter changes and checks to your systems protects against overheated components and allows for optimal air-flow to you and your business.

Refrigeration equipment is designed to cool, but what most people don’t know is it is very easy for them to overheat if not properly maintained. We recommend quarterly maintenance to all refrigeration equipment to ensure your units stay cooling properly and efficiently.

Cooking equipment used in commercial kitchens is run at high temperatures for long periods of time. This causes components to become brittle and weaken over time and units often need re-calibration or cleanings. Routine maintenance to your stoves, grills and hot side equipment allows you to continue to cook at the correct temperature without disruption.

  • United Service is an outstanding family owned company, we here at Finz Seafood and Grill and Sea Level Oyster Bar have been using them for 15 plus years. Ron, Nic and Alexi and their team have been great to work with, to calling in issues and getting right out to fix the problems and finding parts quickly.

  • We called United Service Company when our ice machine stopped working on a Friday morning.  Our hall was booked for the weekend and buying ice was not an option.  The technician, Nate, was there within a couple of hours and had us making ice again and FAST.  United Service Co was fast, professional, and courteous.  We will DEFINITELY use them again in the future!

  • This has been the second large walk-in purchase from United. Both purchases were installed on time and on schedule. United also services our coolers and responds quickly to last minute service calls. I truly enjoy the relationship with United Service.
