This commercial client knows that breakdowns cost more than just money, but precious time and client satisfaction. So, they take advantage of our annual maintenance program with our "No breakdown guarantee". We performed a complete check on the system, cleaned the filters, and checked the pipes for clogs. The client knows they can count on our great customer service and professional expertise.

Arrived on site to perform furnace diagnostic on 2007 Bryant heater. Upon arrival Mr. King stated that the unit is not heating up and they’ve had multiple issues throughout the years they have lived there. No maintenance and service has been done recently. Began diagnostic at indoor furnace and immediately saw that evaporator coil is not correctly piped and has consistently leaked over onto the furnace. Control board has water damage on back. Indoor blower motor has significant oil leakage which will lead to it locking up or overheating. Advised client that heat exchanger should be pulled and tested to verify that it is safe. At this time control board will have to be repaired and it is a possibility that gas valve may have been damaged by water as well. Clients are interested in replacement and have been dealing with issues with the system for years. Supervisor will be returning on Tuesday to go over options. Went over all recommendations and clients are aware of current Failure poi

Arrived at customers house to preform two 20 point furnace maintenance inspections. When we arrived on site the customer had both units on in heat. We went into the garage attic and started on the system there. Upon first glanced I noticed the ducting was a little undersized. This was mention to the customer. Next we looked at all electrical connections and took our amp draws and checked limit switches. Both were looking good and were within range. Next we took a look at the filter, 16x25x5 merv 16 was looking good and did not need to be replaced at this time. Flushed condensate drains and made sure they drained properly. Checked flue vent and gas piping for any leaks. There were no gas smells or leaks while system was running. Next we headed down to the downstairs unit in the basement/craw space. At first glance the unit looked like it was running properly. We opened the system up and started taking our electrical measurements. All electrical on downstairs outside unit was good and

Arrived on Site to perform diagnostic on 1991 furnace. Homeowner states that system is not heating. It stopped working on Friday, worked again on Saturday and stopped working on Sunday and hasn’t worked again since. Cycled system for heating. Unit initiated heating cycle, but ignitor never turned on and system eventually locked out. Tested ignitor and it is bad. Also tested circuit board and circuit board is starting to fail, has not failed completely. Circuit board is failing to send voltage on every call for heat. Sometimes it will send voltage and other times it won’t. Blower motor has leaked significant amount of oil. Ductwork is old and inefficient. No AC. Went over findings and recommendations with homeowner. She would like to go over replacement options due to cost of repairs and age of equipment. Turnover appointment set for tomorrow December 13 from 2-4. System is not operational upon departure.

Arrived on site, homeowner stated his electrician told him the system does have proper power and my diagnosis was wrong. After thoroughly checking everything over, system still DOES NOT have the proper power, and there is an electrical problem causing the unit not to turn on. Wired the unit into disconnect from other unit to show him that it’s an electrical problem. Unit turned right on. Switched everything back, unit is not operational upon departure. Collected diagnostic fee.

Arrived on site to perform diagnostic on 2002 York unit. Upon arrival Pat stated that just yesterday around 3 o’clock the indoor blower motor randomly turned on and will not shut off. Proceeded to indoor unit and found that blower motor was running continuously. Disabled power to unit and blower shut off although when calling for cooling blower motor did not turn back on and condenser was running by itself. Relay has become defective on circuit board and will need to be replaced completely. This may have been due to a power outage or due to old age. Also found that indoor blower motor had significant oil leakage and debris buildup. The indoor blower motor is responsible for moving air around the house in cooling and heating mode. Discussed full diagnostic with Pat and he chose for a mid range repair to be done and would also like to sign up on maintenance plan to keep both units in a standard. They have recently just moved in and have many expenses and would like to just get it runni
