Maintenance Agreements & Tune-Ups

Commercial

Preventive Maintenance Agreements

A warm walk-in or a dead rooftop unit costs you product, customers, and an emergency bill. A D1 agreement puts your equipment on a regular schedule, so problems get caught early and fixed during business hours.

Equipment we cover

Walk-in coolers and freezers
Reach-ins, prep units, and display cases
Rooftop units and heating equipment
Kitchen exhaust and make-up air

What We Check

A Real Inspection, Not a Quick Look

Every unit in your agreement gets checked on a schedule. Here’s a sample of what that includes.

Every Visit

Box temperatures vs. setpoints
Run through cooling and a full defrost
Pressures, superheat, and charge
Fans, motors, and coils
Drains, pans, and heat tape
Door gaskets and leak signs

Twice a Year

Filter drier pressure drop
Defrost controls and settings
Thermostat and sensor accuracy
Electrical connections and contactors

Once a Year

Condenser coil cleaning
Electronic leak check
Amp draw on compressors and motors
Pressure safety switch tests

Rooftop units get spring cooling and fall heating startups, filters, belts, and safety checks.

How It Works

Pick Your Schedule

Quarterly, Bi-Monthly, or Monthly

Choose how often we visit. Sites with a lot of equipment usually do best with monthly visits.

A Report After Every Visit

What we checked, what we found, and what we recommend, by email. Plus a service record for every unit.

Priority Emergency Service

Agreement customers go to the front of the line, 24/7.

Discounted Repair Rates

Lower hourly rates on repairs outside the agreement, and nothing is done without your approval.

Questions

Maintenance FAQ

What does a home tune-up cost?

Home tune-ups start at $100 per visit. Most homes do two a year: cooling in the spring and heating in the fall. We give you the price before any work starts.

What's included in a commercial maintenance agreement?

A set number of scheduled visits per year (quarterly, every other month, or monthly) covering the refrigeration and HVAC equipment we list in your agreement, a written report after every visit, discounted rates on repairs, and priority emergency service.

How is a commercial agreement priced?

Every site is different, so we quote each one based on the equipment, how critical it is, and how often you want visits. The annual price is billed in equal monthly payments.

What equipment do commercial agreements cover?

Walk-in coolers and freezers, reach-ins, prep units, display cases, rooftop units, heating equipment, and exhaust and make-up air systems.

Does maintenance protect my warranty?

Many manufacturers require documented yearly maintenance. Every D1 visit is documented, so you have a service record if you ever need to make a claim.
