Upon arrival, found systems not operational. Client had installed new condenser low voltage wires. I came back to hook them up. Tested system. Didn’t need to replace downstairs control board. Would recommend still replacing it because of past issues. Board can possibly fail. Did maintenance on site. Systems are older. 410 condenser on a 22 evap coil. Pressures were way off. Talked about replacement. For the time client is holding off. Units are operational upon departure.

Upon arrival system is still operational. Client was concerned about loud start up sounds from outdoor unit. Did full system inspection. Found issues with system. Compressor amps on start up are higher than what it’s rated for. While running compressor amps are high but within range. Amps will increase with warmer weather. Electrical start components were tested and they are weak. Refrigerant charge is off buy a couple pounds. Possible leak in system. System runs on older refrigerant. Indoor unit is older. Blower motor is leaking oil and can fail soon. Return duct is restricted causing the motor to operate harder than normal. Informed clients of repair options and replacement options. System is operational upon departure.

Upon arrival, found multiple system issues with design/ performance and electrical failures. Both systems would fail during cooling mode. Systems would cycle on for a second the shut off. Low voltage power would cycle. Upstairs system had a bad board and transformer. Thought possible power surge issues. Once board was installed on upstairs system cycled power. Low voltage fuse failed. Inspection found home warranty had rigged the outdoor condenser wires. Need to run new low voltage wires. Advised client. Client will handle running new electrical wires. Client will call us out to hook it up to the unit. It’s still possible we need to replace the downstairs system board. Once everything is hooked up we will test system. Design issues: system has a R410 condenser and a R22 evaporator coil. Client already replaced the compressor because of refrigerant issues.

Arrived on site to perform diagnostic on 1996 ComfortMaker system. Homeowner states that system upstairs is not cooling. It is blowing air but is not blowing cold. Cycled system for cooling. System kicks on normally, but not removing any heat. Checked outdoor unit electrical and system components. Gauged up to unit to check refrigerant pressures. Found unit to be low on refrigerant, which is causing it not to cool correctly. Refrigerant should never need to have refrigerant added me which means that it has a refrigerant leak. Went over findings and recommendations with Quinn. He is fully aware of the condition of the system, and we have been letting him know that his units have been on the verge of failing due to age and condition. Does not want to repair unit as feels it makes no sense to, and would like to replace. Darren has been out to quote in the past, and homeowner emailed him yesterday. Since Darren will not be back in till the 18, homeowner would like to move forward with some

Arrived on site to perform AC maintenance on 1996 condensing unit. Upon arrival client had questions regarding a new thermostat and potentially swapping it out and also stated that the system has had no issues ever since they repair was done in the summertime. Preformed full maintenance on System and at the end I went over a few points of concerns that were addressed. 5 ton system- 1. Dual secondary motor control is weak on compressor side terminal and will lead to the compressor or this part failing at any point. Recommend the Motor controls replaced to get proper power to compressor 2. High-voltage distributor had high amounts of ant buildup within the contact points. This was cleaned out although if ants return this can cause issues with making contact to turn the unit on. 3. System Contained R 22 refrigerant which was completely phased out January 1, 2020. At this time pressures were in a good range although ambient temperature outside was under 60° 4. Compressor is using 21 amp w

Arrived on site to perform fall tune up on a 8 year old good Man Unit. Client stated no issues and is all good. Cycled heater. Filter was still good. Found no sediment trap on gas line. Blower assembly is dirty. Motor is good no oil at this time. Secondary secondary motor control is good but just boarder line at this time. Run amps are good on both motors. Temperature rise is good and heating home. Only found one drain line and would recommend adding a over flow switch to prevent overflow. All other safety switches are operational. No protection on unit and would recommend adding to protect from electrical surges and power outages that can damage or even short out systems and components. Cycled unit and went over findings with client and he is aware how unit is running and it’s recommendations. Client did hold off for now and wanted it emailed over and would see what he would like to do. Cycled unit and unit is operational upon departure.
