Heating Maintenances Performed- Upon arrival the three main house systems are operational. Began our maintenance at the two furnaces located in the attic. Inspected electrical components for wear and tight connections. Temperature splits and static pressures taken. Heating components inspected and adjusted. Filters have been changed at this time. Amp draws were measured. Performed a duct leakage inspection. Then proceeded down to the upflow furnace in the garage and inspected it as well. Proceeding to the guest house system, system has power but is low on refrigerant, too cold to achieve an accurate reading at this time and need to come back when it’s warmer. Upon inspection of the two carrier units, one in attic and the one in the garage, we found both blower motors to be leaking heavy oil and amping very high, as well as the secondary motor controls are reading low. The blower housings and scroll wheels on both need to have a pull and clean performed to alleviate the dirt and dust

Performed heater diagnostic on 2020 Lennox Unit. Upon arrival homeowner stated that just about a week ago he noticed that the system continuously runs in fan mode and does not produce heat. During the troubleshooting I noticed initially that to the burners Appear to be orange and not burning properly. Also noticed rat droppings inside of the Furnace closet area. At this time it appeared that oxygen was not being supplied properly to the propane burners Resulting in a hard lockout causing rollout switch to be tripped. Previously the original Heater was also clogged up due to rats making it their home and stuffing debris inside of the heat exchanger Resulting in a similar problem. Also main door that covers up the furnace has no air circulation for oxygen the flow recommend that Louvers are added to increase Airflow to Heater. At this time burner Flames look healthy and blue. System is Heating upon departure

Tech arrived on site. Guest house has a Fujitsu mini split with 4 Cassette head units. coils were dirty and temperature split was low. Added 3lbs of R410A to the condenser. Cleaned coils. Temperature split increased and pressures looked better. Client said units had to be recharged before, indicating the unit has a leak. Did leak detection outside at the condenser but didn’t find anything. To find the leak we would need to do an isolation test to determine which system is leaking.

Arrived on site to perform diagnostic on 1 year old or less mini split. Homeowner had system installed by another company and has not been cooling for a couple days. Has been trying to get a hold of the company that installed it but has not heard back from them. Unit is not cooling and inside head unit is showing an F0 error code, which is associated with refrigerant. Hooked up gauges to unit and found system low on refrigerant which is causing outdoor unit to go into lockout mode. Went over findings and recommendations with homeowner as far as Adding refrigerant and locating a possible leak. While on site, the company that installed it finally gave the homeowner a call back and they said they will be sending someone out on Friday to see what’s going on with the unit. Homeowner wants to hold off on any repairs with us for now until the company comes out to see if they take care of it. System is not operational upon completion.

Performed Furnace diagnostic on 2017 Goodman heater. Upon my diagnostic customer Had stated that he has had nothing but problems with the previous company that has been doing the contracting work for his house. He was told that his heat exchanger has a crack, that why the Carbon monoxide detectors are going off. Upon my diagnostic I first found the exhaust vent had been completely pulled off along with nothing but soot coming out of the vent. The reason for the high amount soot Was caused by a failure to convert natural gas set up to propane. This has caused the propane to form into this clogging up the heat exchanger. With the condition of the heat exchanger being filled with soot this is extremely unsafe and has ran like this since 2017 without being converted. Found that there was also no emergency drain pan, they disconnected primary line coming off of the evaporator coil along with none of the duct work being sealed up on the supply take offs. System was installed poorly and unsaf

Arrived on site to perform maintenance on 18 year old Rheem heat pump. Cycled system for heat. Checked systems electrical and components. Temperature split is in range, refrigerant levels in range however System is operating on r-22 refrigerant that has been phased out. Indoor blower motor has leaked out a significant amount of oil and amp draws are fairly high and inefficient. Primary motor control has some burning and pitting on contact points. Comrpessor amp draws are also high and condenser fan motor is leaking oil as well. Performed coil clean. Blower wheel is slightly dirty. Replaced 1 inch filter. Ducting is in very poor condition. Attic has enough space for a possible relocate in the future. Went over findings and recommendations with homeowner. She is fully aware of the condition of the system and is aware that she will have to replace in the future. She has gotten quotes in the future And have an idea on what a project like that would consist of. Offered to have someone come

Arrived on site to perform warranty on system. Homeowner states they tried to turn on the heat and they got an error code and it didnt work. Error code 270 was displayed on both units, which is error code for no flame sensed on unit. Systems are both dual fuel units. Upon inspection of units found that settings are not set correctly on circuit board for dual fuel. Settings call for jumper W951 on circuit board to be cut in order for unit to recognize that it is a heat pump dual fuel application. Cut jumpers on both systems circuit boards, and reset systems for them to update changes. Cycled systems for heat. Systems came on and started heating, no error codes displayed on either unit. Noticed that thermostats were not connected to WiFi. Helped homeowner hook up both thermostats to WiFi and link them to her phone app. Ensured thermostats are communicating with phone applications. Cycled system, systems are operational upon departure.
