Was called pu for a IAQ evaluation. Introduction and call expectations met. Homeowner gave a tour of the issue at hand. Homeowner noticed biological growth coming out of supply vents. Homeowner has a maintenance plan with daffen but is not satisfied with their care and expressed does not want them back out. My diagnosis- Homeowner came into the attic with me and I took that time to educate Homeowner on all of my activities. Indoor unit of the main system is 2018 and has heavy amounts of biological growth inside the cabin; evaporator coil, blower hub, blower wires and door insulation. The blower wheel itself has a layer of buildup. To be thorough, I pulled up the diverstech saftye float switch to see what the primary drain condition was and found a blocked line with a ring of sediment on the float swith itself. As I put it back in place, the alert red light lit up. I took this time to clear the drain line throughly as the low voltage power was not passing through to the thermostat.
2017 (I think) 3 head minisplit hp. No manufacturers warranty. System functioning upon arrival at a reduced performance. Last tech put refrigerant in and it only lasted a few weeks. I have video and photo evidence of a leak inside condenser unit on the vapor line. I educated homeowner on the cost of repair vs replacement. CA appointment set for 8/13/24 @5pm to discuss replacement.
Arrived for evaluation System has refrigerant leak Added refrigerant System left on cool at exit
Customer was not at the home upon arrival. Was connected by phone. Customer states possible damage from transportation, error code on indoor unit stating low to no r410a. Data tag states 40.6oz. Gave an estimate over the phone to refill, stating that it could be up to $xxx amount. At that point, the customer said he'll probably purchase another one later. Offered a Comfort Advisor visit - declined. Customer is building a home on the land and is staying in his mini home on wheels. No "tune-up" was able to be done due to not having access to indoor unit while customer wasn't home.
