Ever wonder how an Ice machine works or what it looks like on the inside? This picture is showing the pump float (float switch), and the evaporator (evap).

A float switch is a water level sensor that is located in the sump. It rises and falls with the water level.

An evap is the cold plate or grid where ice forms. Refrigerant flows through it removing the heat from the water which then freezes and ice builds into cubes.

Typical Operation cycle:
1) Machine fills with water
2) Float rises which signals proper level
3) Pump start and water flows over evap
4) Ice forms on evap surface
5) Water level drops slightly where the float may trigger to refill
6) Cycle continues until harvest phase.

Don't wait call Collins Commercial Services to ensure that your ice machine is working and kept cleaned correct#collinscommercialservicesv#Arizonai#havc##IceMachinec#floatswitchwitch

Time leaves it mark even ion the smallest parts, this flush valve tells a story of years of use, water flow, and slow corrosion beneath the surface.

A flush valve is a critical component in a toilet or fluid control system that regulates the release of water. Over time, exposure to moisture, minerals, and oxygen can cause oxidation, leading to rust, especially in older metal valves.

Don't leave it to chance, give Collins Commercial Services a call today to ensure your flush valve is working properly#collinscommercialservicesv#plumbingm#Arizonai#texasT#flushvalveValve

Yeah, 107 this weekend in Arizona is no joke, your AC is basically your life support at that point.

A little preventative maintenance now can save you from a breakdown when you need it the most.

Professional AC preventive maintenance (PM) is a comprehensive "health check" for your cooling system typically performed twice a year, once in late spring, and again in late fall.

It involves a combination of deep cleaning, safety inspections, and performance tuning to ensure the unit runs efficiently.

Call Collins Commercial Services today for your PM so we can ensure that your unit will get you through the summer.

PCB? wait, what is that?

Air conditioner control board is the central hub that manages power, fan operation, compressor cycles, and safety controls within the HVAC System. Basically it is the "brain" of the AC unit.

Here are some things the control board does for your unit:
*Regulates the compressor
*controls the fan motor and blower
*interprets signals for the thermostat
*monitors safety switches
*Manages timing delays to prevents system damage

A fuse block on a water heater is basically the bouncer of your water club!!!

A fuse block on a your water heater is part of the electrical protection system. It contains fuses that act as sacrificial devices. If the current flowing to the heater exceeds safe levels, the fuse "blows" and cuts off electricity to prevent damage, overheating, or fire.

Who wants a hot mug in the middle of summer?

An Evaporator coil in a mug chiller is where the cooling magic happens, pulling heat away to keep the mugs perfectly chilled.

The evaporator coil is part of the refrigeration system inside a mug chiller. Cold refrigerant flows through the coil, absorbing heat from the surrounding air and the mugs placed inside the unit. As the refrigerant absorbs heat, it evaporates from a liquid into a gas, which is why it’s called an “evaporator.”

Don't let your customer drink out of a warm mug. Call us at Collins Commercial Services so we can ensure that your mug chiller is running properly,
