Bloomfield AC Repair and Maintenance

We are a reliable Bloomfield heating and cooling service and repair provider.

We service Packaged Units, Ducted Split Systems, or Ductless Mini-Split systems. Refrigeration gas "Freon" differ from one system to another, we master freon leak detection and we provide our customers with the professional Life Cycle Cost analysis of freon recharge/repair or to change a system altogether.

Our Light Commercial Refrigeration

Commercial refrigeration systems such as Pizza Prep Tables, Walk-in coolers, Ice machines, and freezers have equivalent architecture and similar components, a compressor, a condenser coil with fans, a metering device, an evaporator with a fan, and some controls such as a thermostat or defrost timer.

commercial refrigeration system explanation in bloomfield

Year after year, documented evidence showed that preventive maintenance, commonly referred to as tune-up, proved to be more cost-effective than emergency service repairs.

With a tune-up, parts are replaced before they break and before causing widespread damage. On the other hand, repairs require much longer diagnostics and usually broken parts cause a chain reaction of broken elements or DBR Damage Beyond Repair.

Many service technicians, check the refrigeration levels on annual basis. Contrary to common practice we do NOT recommend checking Freon levels unless necessary. There are signals to hint at a low freon charge (either caused by a leak, or a poor recharge by an un-trained service person.)

Note: each Gas pressure measurement traps some freon in the hoses. As such, some freon is lost and never makes it back to the refrigeration system.

Believe it or not. With comfort systems, electrical problems happen more frequently than Gas problems.

We guarantee our work and you will be satisfied.

Residential AC Tune-up Checklist

Beware of claims about a "60-Point Tune-Up"! Scammers might try to trick you with fancy marketing, but there's no such thing as a 60-point tune-up for your residential central air conditioning. Look closely at the details to avoid falling for scams. In reality, a proper maintenance check usually takes between 45 minutes to 1.5 hours per unit. Don't be fooled by lists that promise too much – they're just for show and often include services that could never all happen in a single visit. Stay smart and read the fine print!

Restaurant Equipment Repair & Maintenance in Bloomfield

We provide professional restaurant equipment consulting and repair services. This is a comprehensive program at no extra cost focused on reducing and hopefully eliminating restaurant unexpected shutdowns and Emergency Service Repairs. Our program includes

 

Walk-in Cooler & Walk-in Freezer Service

Restaurants, and food & beverage establishments can not do without Walk-in coolers or walk-in freezers. When these systems fail, unless repaired immediately shutdowns cost business owners thousands of dollars in wasted food and more importantly customer loss.

Finding OEM replacement is a literal costly nightmare. Expedited overnight shipping costs are not the best option. Under urgent situations, some technicians make temporary patches that end up permanently in a given installation, unfortunately, this practice leads to future problems.

We have seen ice cream business freezers shut down in the middle of summer, the busiest season, a Tune-up preventive maintenance program would have totally eliminated the service call. 

Dirty coils and dirty filters will cause air flow restrictions which will ultimately have an impact on the fans, and compressor making the system work harder and less efficiently and creating the perception of low Freon refrigerant. 

Get your preventive maintenance in place to reduce shutdowns. We worked with operation-critical hospitals to avoid shutdowns and preventive maintenance was the key to success.

Best Practice for Walk-in coolers and freezers in Bloomfield

 

We offer our customers many services with the best possible advice: 

  • Clean the condenser coil
  • Scan for freon Leak
  • Check amps Compressor / Cond & Evap Fans
  • Install infiltration reduction curtains
  • Inspect gaskets
  • Automatically Log Temperature
  • Optimize Defrost Cycle and Termination
  • Ensure the drain line is clean
  • Install excessive open-door alarms reminders
