12-30-24 Isaac J. Came out to call for a system not heating properly. Customer stated that the heat pump kept shutting off and coming back on without completing a full heating cycle, so they turned it off. I checked the system overall and found the unit faulting on high pressure due to a bad blower motor. Discussed with customer about repair needed. System is still under warranty until June of 2025. Customer approved warranty repair and picking up part. Let customer know that it was going to be available tomorrow. 12-31-24 Came back out to replace blower motor. Pulled blower assembly and took existing motor out. Installed new blower motor in bracket and installed it into the assembly. Reinstalled assembly back into air handler, wired motor in and cycled unit in all modes on thermostat to confirm system as operating properly. Discussed with customer about maintenance plan for unit, but they aren’t interested at this time. Still recommend unit be serviced next spring. System is now oper

Came out to perform preventative maintenance on furnace. Discussed with customer about maintenance, filters needing cleaned, and any concerns he may have. Customer stated that the system has been working fine so far. I pulled the electrostatic filters out and cleaned them thoroughly. Inspected blower assembly, motor, electrical components, burners, flame sensor, igniter, inducer motor, heating drains, heat exchanger, coil and overall condition of equipment. Cleaned flame sensor and dust out of the burner compartment. Made sure condensation hoses were clear. Checked thermostat operation, wiring, amps, temperatures and gas pressure. System is heating properly within manufacture specifications at this time. Customer could benefit from having the ductwork cleaned out.

Jake Kring. 11-23-24. I arrived for a new customer no cool call. The homeowner explained that they have heat but did not have any cooling. He showed me the system and I found it to be a 13 year old R22 condenser with a downflow air handler. I inspected the system with the homeowner and we found the terminals to have blown out of the compressor. The system holds 14 pounds of R22 per the manufacturer data plate. I explained that the cost of replacing the compressor would be about half or more than half of the cost of replacing the system. I also explained that he would need to replace the R22 indoor unit and that he could not put a R410A system on a R22 indoor unit. We looked at the cost of the refrigerant and the cost of replacing the compressor without the cost of the compressor. He also wanted a ballpark quote on replacing the system. I will be looking for the compressor cost and will be following up with the homeowner Monday.

Duct cleaning, new customer. Andrew J and Kianoosh M out to inspect ductwork. Spoke with homeowner and they h ave cats they do not want let out. Inspected ductwork and found it to be composed of older gray Mylar and falling apart. A duct cleaning would only tear this ductwork up. Talked about leaving an estimate for new ductwork and customer asked for one. Also left an estimate for blown insulation as an added courtesy. System needs 9 total supply cut ins. Attic insulation has older brown insulation between 1 and 3 inches throughout. Please let us know if you have any questions or concerns. Thank you!

Completed duct cleaning for customer. Spoke with customer after introduction about a duct cleaning inside their home. Home has 13 supplies and 3 returns. After inspection, I was able to confirm cleaning. After confirmation, I laid out drop sheets under every vent, took down all grills and cleaned with duct cleaning machine and did each duct for 4-5 passes each. And then sprayed hospital grade disinfectant for about 30-60 seconds. I then swept up any messes that drop sheets didn’t catch and then replaced filters and cleaned up any messes before collecting and leaving.

Jake Kring. 07-03-2024. I arrived for a 18 year old system not running the blower motor in the air handler. The homeowner showed me the location of the system and I found that the control board and model were not communicating to run the motor. I tried to bypass the control to bring the motor on separately from the thermostat and condenser and had no luck. I called for availability on this system and found that the parts will have to be ordered in. I informed the homeowner of the part availability and the delay being a holiday and that it will delay some of the shipping for the parts. I explained how the system operates and we discussed the possibility of installing a single speed motor in place of the variable speed motor. Due to cost of the OEM part replacement. I explained that I can do it but I may need additional sequencers or relays to get the system to operate in all heating and cooling modes due to it being a heat pump and a electric heating air handler. I priced both possible

Came out to call for a no cool. Customer stated that the AC wasn’t cooling properly and was running constantly. Checked system over and found the unit super low on refrigerant. Discussed with customer about my findings. The condenser coil has been peed on by several dogs and has eroded the bottom of the condenser coil about 6” around the front of the AC unit. When we installed it, I did advise that customer put a blockade around the unit to keep the dogs away from it. Told customer that I would do a complimentary leak search. Found leak in condenser coil. Went over options with customer. Customer is going to hold off for now and have the work done another time due to financial reasons.

Jake K. I arrived for a blue club membership summer tune up. I first spoke with the homeowner and found that the system is running well and keeping temperature. I checked the indoor system and found the evaporator coil to be extremely rusted and sticky. I also found the drain line to have a lot of buildup the drain line. I tried to blow the drain line out but with the weight of the drain line there is scale in the drain line that is not moving out. This system doesn’t have a safety switch on the system to turn the system off if it starts to leak water. I then inspected the outdoor system and found it to be clean but the condenser fan motor is leaking oil at this time. I also found the contactor to be blackened and pitted. I replaced the filters and brought all issues that I found that I would expect to be a problem to the homeowner this year. She will have to get with her husband to decide if they want to do anything with the system and get back with us to address and issues.

Came out to perform preventative maintenance service on AC system. Discussed with customer about maintenance being provided, filters, and any issues they may be having. Customer stated that the system worked fine this winter, and just needed the AC tuned up. I cleaned the filters inside electrostatic cleaner. Inspected the blower assembly, motor, electrical components, evaporator coil, drains, and overall condition. Washed condenser coil thoroughly. Inspected the fan motor, compressor, contactor, capacitor, start kit and coil condition. Checked thermostat operation, wiring, amps, temperatures and pressures. Found system running just out of recommended ranges on pressure/temperatures. Discussed with customer about the system needing refrigerant. Customer approved adding a pound of refrigerant to system. System needed about .8lbs of refrigerant in 2022, and needed about the same amount this time. Added 15oz’s to system to get in proper ranges. Customer will call tomorrow to make payment.

This is an estimate for increasing the existing returns, and cutting an additional return in. System requires around 1400 cfm, and customer currently has around 700. Recommended increasing main return from a 14” duct to a 16” and cutting in another 14x30 grill with a 16” on the opposite side of the living room. Adjacent to the existing 14x30. This would give the customer roughly 1450 in return air cfm.

Customer had insurance look everything over, but wanted me to be aware in case there were any electrical issues that the insurance company didn’t catch. I started my inspection with the equipment in the attic. Inspected ductwork, evaporator coil, blower assembly, motor, electrical components, heating elements and overall condition of equipment. Checked operation, amps, and temperatures of heating elements. The return duct work is still undersized for the system about 45%. Due to the layout of the home, we discussed different options again to help increase the return air, and limit the possibility of another breakdown. Ended my inspec

Customer also stated that the thermostat has a Cmmon wire, but the thermostat went blank when he changed the batteries. I checked the system over and found a loose thermostat wire to R for power.

Jake K. I arrived for a new customer air flow control problem. I spoke with the homeowner and found that they are having to change the thermostat constantly to keep the home comfortable. He showed me the system in the attic and I found the system to be a 21” wide air handler with a undersized plenum and no dampers to be installed on the system. I showed the homeowner the system up and explained that the system is bottle necking the air due to the small plenum and just adding dampers to the system will only reduce the air flow vs balancing the air flow. For the system to balance correctly we will need to replace the 4’ plenum with a 6’ plenum and add damper taps to control the air flow and open up the area the air can flow. The homeowner decided to wait to do the work next year.

Came out to call for a preventative maintenance on system. Customer changed filters recently and has no issues with how the system is operating. I inspected the condenser coil, capacitor, contactor and other electrical components. Checked amps, temperatures and pressures in heat pump mode. Cycled emergency heat as well and checked amps and operation of blower. System is a little over 2 years old and is operating properly within manufacturing specs. Discussed with customer about issue he was having with his upstairs mini split not heating. I checked the system over briefly and the unit will not switch to heat mode due to possibly being low on refrigerant again and can’t make the changeover. Customer wanted to schedule a time to come back out and look into it more to see what we can do to fix it. Happy Holidays!
