What about fall maintenance for heating systems?
clear

Chris Joiner, Senior Technician answers this question.

 

For residential heating the most common types in the Nashville area are heat pump, gas and straight electric.  Since a heat pump doesn’t work with temperatures below 40 degrees such systems need to have auxiliary or emergency heat sources.  These sources are normally either natural gas or straight electric.  Technically it’s not emergency electric heat but rather  auxiliary heat. When you set the emergency heat thermostat switch to on, the outside compressor is turned off.  This leaves the electric heat as the only source of heat.  Normally,  electric heat does not come on until the thermostat tells it to.

The fall preventative maintenance steps for heat pumps with electric auxiliary heat are as follows:

  • Check amp draw on electric heat is per specifications
  • Check all safety devices are working properly
  • Check the refrigerant charge level is per specifications
  • Check amp draw for the compressor is per specifications
  • Check amp draw on the blower and the condenser fan
  • Wash coil if necessary
  • Check the filter and replace if dirty

 

The steps for heat pumps with gas auxiliary heat  are:

  • Measure amp draw on the induction motor.
  • Measure gas pressure and check against specifications
  • Check the heat exchanger for any holes or cracks
  • Check all safety devices for proper operation
  • Check the refrigerant charge level is per specifications
  • Check amp draw for the compressor is per specifications
  • Check amp draw on the blower and the condenser fan
  • Wash coil if necessary
  • Check the filter and replace if dirty

When are new technicians ready to handle service calls?
clear

Tony Anderson, Partner answers the question this way.

After we have hired a new technician, I find that some are ready to go out the first week.  Others could take a year of training and coaching.  It depends on the individual and their experience level.  We classify technicians as Seniors, Juniors, Sophomores, and Freshmen. A Freshman could be 55 years old. We need those people to wash coils and perform the straight forward maintenance tasks such as changing belts and filters. Of course you also have to have a superb group of Juniors and Seniors to lead our service department and teach our process. No one man can do it all it takes a team effort.   The Juniors and Seniors will typically only need to ride with another technician for a week or two just to learn our system. Then they will be ready to hit the field on their own.

Choosing a Repair Company
