Preformed 2 system maintenance on a 2021 and 2012 gas systems. I tested all electrical components on both systems. All tested within manufacturer specifications. I tested each drain line and treated with totalc and water. The downstairs system could benefit from a duct cleaning. The upstairs condenser unit could benefit from having a hard start kit and condenser cleaning. Both units were cooling upon departure

Here are clean, professional summary notes you can use: ⸻ Service Summary Notes • Visited customer’s home to complete fresh air system setup. • Installed and connected transformer to the Aprilaire fresh air device. • Configured the controller to operate 15 minutes per hour to introduce fresh air into the home. • Verified system operation — fresh air system is now fully active and functioning as designed. • Confirmed all electrical connections and components are properly installed and secure. Status: System operating properly, no issues at this time.

Upon completion of my thorough evaluation, I found that both systems could benefit from having a full system cleaning done on them. By doing this you can help improve air quality in the home and help keep all major components working at their peak performance and efficiency. Also the client is currently using 20x25x1 inch filters. By upgrading to the Aprilaire 210 filters you can help combat against allergens and help keep all the major components clean. On the outside unit i notice there wasn’t any type of surge protection, by adding surge protection you can help prevent damage from being caused by lightning strikes and other types of power surges. I tested all electrical components on inside and outside units all tested within manufacturer specifications. I flushed and treated drain lines with total c and water. I rinsed the outside units with water. Units were cooling upon departure

Unit going into thermal over load on the blower motor due to an extremely dirty filter. Client wants filter changed. Advised will need to come back tomorrow to change it.

Preformed single system heating maintenance on a 2022 communicating gas furnace. I tested all electrical components on the inside unit. All tested within manufacturer specifications. I did changed the filter for the client. Filter size is Aprilaire 213. I did find that the blower wheel has dust build up on the fins. This can cause drag and not allow the blower to work at full capacity. It also could result in having the motor prematurely fail. A cleaning of the blower wheel and assembly could help prevent any issue that may occur. I proceeded to visually inspect the outside unit. I found the outside unit to be in good proper working order. Unit was back to clients set point on the thermostat and working properly upon departure.

Preformed Dryer Vent Cleaning. Preformed 2 system heating maintenance gas systems. I tested all electrical components and safeties on both units in the attic, along with cleanliness. All electrical components and safeties were testing within manufacturer specifications. Overall cleanliness of the unit was satisfactory. Clients filters did not need to be changed at the time of inspection. I ran air advice to test the air quality throughout the home. Air advice report came back testing very good air quality. I did notice both units inside and outside did not have surge protection on them. I provided estimates to have full system surge protection installed to both upstairs and downstairs units. I placed both thermostats back to cooling and both were cooling upon departure.

We replaced the planum, connected all the ducts, and sealed everything.

After inspecting your HVAC system, I strongly recommend replacing the current 3-ton unit. We are performing a load calculation for the home. Given that this is an Airbnb with higher and more variable occupancy, a 3.5-ton system is likely a better fit to maintain comfort and reliability. Condensate Drain Line Concerns • You mentioned ongoing issues with the drain lines. • Our install team will flush and attempt to clear the existing condensate drain lines during installation. • If we cannot clean them sufficiently to restore proper drainage, I recommend installing a condensate drain pump to ensure reliable condensate removal. • Please note: a condensate pump is not included in the equipment estimate and would be a separate line item if needed. Scope Clarification • This proposal covers equipment replacement and standard installation. • Ductwork modifications are not included in this estimate. If duct changes are required after the load calculation or during installation, we’ll p

Estimate on a duct cleaning. Upon arrival customer stated that she’s selling the house and has a showing this weekend. Customer is wanting her ductwork cleaned to remove any odor in the house that might be unpleasant for a buyer. During my inspection I checked the ductwork and found them to be dirty, I showed my pictures to the customer and she agreed that they could use a cleaning. We will perform level duct cleaning on a single system home this Wednesday August 27th, we will arrive between 8am-9am. I also informed the customer about our air purification system to help purify the air and help remove odors but she isn’t interested at this time and only wants to do the duct cleaning for now. Customer is paying with a check and paid a $250 non-refundable deposit today via check.

Arrived on site, and found drain line not draining properly. Blew out drain line with nitrogen and line would drain initially. However, I would receive back pressure shorty there after stopping the line from draining. Adjusted pitch of drain line to ensure that was not the issue, and had no different results. Upon tracing the drain line, I found water leaking out of the cast iron vent pipe that the drain line was tied into. Advised homeowner that unit may not work properly until this issue is addressed and that a plumber would need to address this issue. I advised the homeowner that we could run another drain line draining outside into an irrigation box, however I recommended addressing the larger issue with the vent pipe. Unit running upon departure, and drain line intermittently draining.

Upon arrival, I found the compressor was off on thermal overload. I cooled the compressor down and checked my refrigerant pressures. The system is low on 410a refrigerant. The system is a 2012 gas system. I presented options to the customer to address the issue. I offered filling it up with refrigerant, filling it up with leak seal, and system replacement. The customer elected to proceed with system replacement. The customer chose the 14 seer2 American standard 5 ton gas complete. It is scheduled to be installed on Thursday. 7/31/25. I collected half as down payment for the install.
