Customer was having concerns about system running and stopping off and on. System would run for about 5 min and then shut off. It would then go into a 5 min delay before it would run again. Took thermostat off wall and jumped the wires together, system stayed running for over 10 minutes. Customer had new thermostat, replaced the old one and programmed the settings. Tested system in cooling and system continue to run. System is cooling at this time.

No cool on split heat pump system. On arrival, indoor blower was running but condenser was not. Checked voltage at contactor, getting 24v from air handler. Getting 240v to bottom of contactor but not at the top. Contactor is bad. Found ants had crawled inside and it was not sending voltage through. Replaced contactor and tested system. Checked refrigerant pressures and subcooling. System is cooling at this time.

Customer was having concerns about system not keeping up with thermostat. Checked temperature drop across coil and only getting 12° difference. Checked refrigerant pressures and system is low on refrigerant. Customer declined leak search and just wanted to add refrigerant. Added 3 lbs of refrigerant and temperature drop has increased to 19°. Sending estimate for leak search too in case the system stops working again.

Arrive for no cool. Customer stated breaker was tripping. Also before breaker was shutting off, system was not able to keep up with set temperature. Inspected breaker and determined that it won’t stay on its own. This will need to be replaced by an electrician. While we were there, connected gauges to system. It is completely empty. Customer is getting breaker fixed and then we will come out to check compressor and search for a leak. If leak is found in the coil, system will need to be replaced due to it being out of warranty and type of refrigerant. Talked with realtor and she is going to talk to the homeowners.

Return for system not cooling again. On arrival, outside unit was running but indoor blower was not, coil was frozen. Error code was for clogged drain line. Once I pulled float switch out, the blower came back on. The primary drain line is clogged up. When the float switch would trigger, it was only shutting the blower off but keeping the condenser running. This is what caused it to ice up. Cleared drain line using nitrogen. Poured water down it to verify it was clear. Wired float switch up to shut off the thermostat completely. This will shut everything off rather than only the blower. Tested float switch operation as well. System is cooling at this time and drain is clear.

Arrive for no cool on single system. Customer had coil freeze up over the weekend and stop cooling. After customer talked with Jesse they turned the unit off completely and tried to test the blower. At that time they did not think the blower was running. On arrival, I tested the blower on its own and then turned the system on to cool. Both times the blower came on and ran normally. Checked refrigerant pressures and system was cooling correctly. Subcooling was within acceptable range. Replaced filter, it was dirty but not sure if that caused the problem. Getting 75° at return and 56° at supply, system is cooling at this time and customer will let us know if it stops working again.

No cool on upstairs system. Customer stated that system was not cooling very well. Thermostat was set to 69° on arrival and was 72° upstairs. Checked temperature drop across system and getting 17° difference. Drain line is clear and float switch is not being tripped. Checked refrigerant pressures and subcooling was a little low. Customer approved adding 1 lb of refrigerant and seeing if this helps, declined leak search at this time. After adding refrigerant subcooling came up to an acceptable range. Temperature split dropped by 2° as well. Thermostat is down to 71° after system has been running while we were working. System is cooling at this time.

1 system AC maintenance. Replaced filter provided by customer. Measured temperature drop across system, getting 19° difference. Checked operation of drain line, it is clear and treated with drain solution. Next, went outside to condenser. Measured amp draw on compressor and fan motor. Starting amp draw on compressor is above manufacturer limit, this causes more stress on the compressor and can shorten the life of it. Recommended installing hard start kit to bring starting amps down and prolong the life of the compressor. Checked capacitor and contactor. Capacitor is out of range, replaced it under parts warranty. Cleaned condenser coil using water. System is cooling at this time.
