Air Conditioning System Repairs: Replaced a heavily clogged air filter with a high-efficiency pleated filter, restoring airflow and preventing strain on the blower motor.
Completed AC inspection for customer. All aspects of system tested within manufacturer specifications with the exception of refrigerant charge. Refrigerant is low and coil is hovering above freezing. Notified customer who declined repairs today. Thank you!
Arrived to verify readings and present repair and replacement solutions.
Completed ac inspection all components tested to manufacture specifications. No recommendations at this time.
Completed cooling maintenance on all 5 rtus. Changed all filters. And checked amp draw on all motors and compressor. No usable water source to clean coil with water. Used dry nitrogen and blew coil out to clean. Unis are functioning properly at this time
This morning I arrived and Shannon directed me to the two unit heaters that were not functioning. The first unit would not hold the pilot light and the thermocouple was tested and replaced. The unit heater returned to normal function after the repair. The second unit heater held a pilot light and function normally. It was not functioning today due to the gas having been turned off in the past and the pilot light needed relit. This unit heater is a reznor and is located in the bay door area of the shop. Both of the unit heaters today were checked for proper draft, heat exchanger health, fan motor bearing wear and each was cycled on and off after they were back in service. While they are in good condition I do recommend a carbon monoxide detector in the occupied areas due to the age of the equipment. Thank you, Jon Tech notes: new t-couple Dayton//S/N C7942790. Reznor, relit pilot, in the bay door area
Found gas leak on unit heater. Tightened gas leak and ran system checked for any more gas leaks and found none. Checked all rtus for gas leaks and found no leaks at this time. All units are running. Checked with customer to verify there is no more gas smell they didn’t smell anything and systems have been running for 2 hrs.
Today two unit heaters had a gas line fitting replaced. The Northeast unit heater had a 1 1/4” to 1” elbow replaced. The unit heater next to the office had a 1” to 3/4” reducer replaced. These fittings were requested to be replaced by Matt. Previously the gas to all of the building had been turned off by the gas company due to the N.E. Unit having a leak that was before the unit’s gas shut-off. Matt will be contacting spire to return and perform a pressure check on the building’s gas lines due their shut-down of the whole building. I did advise Matt how to reset the units at the breaker box and the hanging unit heater’s (3) equipment switches. Thank you, Jon Tech notes: client supplied fittings were used. The heat exchangers were checked on both units.
Unit heater 1 Model number: LF24-250A-5 Serial number: 5613E01258 Ran gas leak detector over all gas joints on system found no gas leaks. Checked flue pipe and heat exchanger no holes or cracks system is functioning properly at this time. Unit heater 2 Model number: LF25-250A-1 Serial number: 5619K10305 Ran gas leak detector over all gas joints on system found no gas leaks. Checked flue pipe and heat exchanger no holes or cracks system is functioning properly at this time. Unit heater 3 Model number: LF24-250A-5 Serial number: 5613E01259 Ran gas leak detector over all gas joints on system found no gas leaks. Checked flue pipe and heat exchanger no holes or cracks system is functioning properly at this time

Arrived to do a performance maintenance. Set up for combustion analysis and static pressure tests. Found that the system is operating with failing static pressure. Reached out to a field supervisor to provide up to date pricing on static pressure repairs. Verified operation of all mechanical and electronic components in the furnace. Cleaned the flame sensor and retested its performance. Checked blower for cleanliness and to see if there is any play in the bearings. Found that the blower wheel is heavily coated in debris. Checked systems heat exchanger to ensure proper venting of flue gas. Found that the heat exchanger is heat stressed, showing hot spots. Checked for carbon monoxide in the air stream. Performed an electronic gas leak search. Spoke with homeowner about the system. Furnace is operational at this time.
