What's the difference between a service call and a diagnostic fee?

A service call covers the technician's visit and basic inspection to identify the problem. The diagnostic fee applies when specialized testing or equipment is needed to pinpoint complex issues. Once the problem is identified, repair costs are separate and quoted before work begins.

How often should commercial refrigeration equipment be serviced?

Commercial units need service every 3-6 months depending on usage intensity and environment. High-volume kitchens with constant door openings accumulate debris faster and strain compressors more. Preventive maintenance catches refrigerant leaks and failing components before inventory loss occurs.

What causes an HVAC system to freeze up in summer?

Low refrigerant from leaks is the most common cause, reducing pressure until moisture freezes on coils. Restricted airflow from dirty filters or blocked vents also drops temperatures below freezing. Both conditions force the system to run continuously without actually cooling the space.

When should you repair versus replace a commercial cooler?

If the unit is under 7 years old and the compressor works, repair usually makes sense. Systems older than 10 years with compressor failure often cost more to fix than replace, especially when factoring in rising energy costs from older technology.

Why do restaurant walk-in coolers lose temperature overnight?

Door seals develop gaps from repeated use, letting warm air infiltrate when closed. Evaporator coils iced over from defrost system failures also block airflow. Both issues cause compressors to run constantly while temperatures slowly climb during low-activity hours.

What's included in an HVAC maintenance visit?

Technicians check refrigerant charge, clean or replace filters, inspect electrical connections, and test thermostat calibration. Condensate drains are cleared and blower components are lubricated. These checks catch 80% of issues before they cause complete system failure.

How do you know if a compressor is failing?

You'll hear unusual clicking, grinding, or humming sounds that weren't present before. The unit struggles to reach set temperature, runs constantly, or trips breakers. Compressor failure often follows refrigerant leaks that went undetected during previous seasons.

What causes uneven cooling in different rooms?

Ductwork design issues or leaks in specific runs reduce airflow to certain zones. Thermostat placement in locations affected by direct sun or drafts also causes incorrect system cycling. Undersized equipment for square footage creates the same symptom across the entire structure.

Why does refrigeration equipment fail more in summer?

Ambient temperature directly affects how hard compressors work to maintain set points. Units already low on refrigerant or with dirty condenser coils can't reject heat efficiently when outdoor temps exceed 90°F. Component stress from extended run times accelerates wear during peak months.

What's the lifespan of a commercial ice machine?

Commercial ice machines typically last 10-15 years with regular maintenance and water filtration. Hard water without treatment scales components and shortens lifespan to 7-10 years. Machines in high-volume bars or restaurants wear faster than those in office break rooms.
