How Water Unit Heater in a mechanical room

Unit Heater Sequence of Operation – Mechanical rooms have very important equipment that needs to be protected. Often mechanical rooms are not conditioned and subject to outside temperatures and freezing conditions that can freeze piping inside the mechanical. For that reason, mechanical rooms often have unit heaters located there to protect piping and other things that cannot be frozen or subject to freezing conditions. The components and sequence of operation are fairly simple. The main components in a hot water unit heater include a fan, a valve, and of course the piping and coils along with the cabinet. Unit heater sequence of operation can also rely on an automatic control system but it can also be stand-alone. (more…)

Disconnect and Electric Motor Starter with Overloads

Disconnect and Electric Motor Starter
Disconnect and Electric Motor Starter is used for turning the power off and on the electric motor used in HVAC applications. It also has overloads built into the starter so if one of the windings begins to pull too many amps the overloads open the circuit and the motor stops operating.

Motor starters can be used for single-phase and 3-phase motors and offer a manual way to turn the motor off or disconnect the electricity to the motor to prevent it from starting for maintenance or repair of the motor or peripheral systems. (more…)

Common Air Handler Problems & Maintenance Schedules

Common Air Handler Problems - Air Handling Unit installed in a tight attic.

With proper maintenance, you can avoid common air handler problems

Common Air Handler Problems - Everyone loves to be comfortable, so when there is a problem with the HVAC system, we can become very uncomfortable. The air handler in the HVAC system has electrical and mechanical components inside it that can experience problems from time to time. Some of the most common problems with air handlers can help you identify the problem and possibly fix the issue — many common air handler problems you can avoid with regular air handler maintenance.

Although some of the issues listed will need the attention of a professional HVAC technician to repair the air handler, after all, an HVAC technician will have all the tools and likely the parts available to make a fast and efficient repair. Furthermore, since every air handler is different it is possible the problems described here do not apply to your situation.

Frozen Evaporator Coils Troubleshooting Easy List

Frozen Evaporator Coils Troubleshooting - It was a very hot day and I got a ticket to respond to a call for no cooling. The customer said there was ice on the air conditioner. The heating and cooling service operator instructed the customer to turn the AC off so the ice could thaw before I got there to figure out the problem. It needs to be thawed before any AC troubleshooting can occur. There are two main causes why the evaporator coil will freeze and cause ice on the air conditioner. One is decreased or no airflow and the other is a low refrigerant charge.

For the first problem, you can likely repair it yourself quite easily for some of the cases. For example, on our list below, you can easily change a dirty air filter but I would not expect most people would want to change a bad blower motor. However, for the refrigeration problem, you need to call in a licensed HVAC technician to make the repair. A frozen evaporator coil was frozen for a reason and the ice only diminishes airflow even further making the air conditioner or heat pump totally useless for its intended purpose.
