Customer called and stated that their 10 year old Lennox heat pump is not communicating with the thermostat. He is unable to get the heat pump to turn on or get the fan to cycle. Upon investigation, the technician found that the outdoor coil is deteriorating. He recommended a hard start kit and adjusted the thermostat settings. After cycling heat and cooling twice and verified that all operations are normal at this time.
Customer's Rheem AC unit stopped cooling. She does not recall any error message on her thermostat. Upon investigation, I found that the system is very low on R22 refrigerant. Unit was not turning on during a call for cooling even when proper voltage was there. I inspected all components and all are within manufacturers specifications but when I checked the pressure reading I found that the numbers were too low. I added about 10 ounces of refrigerant to see if unit would come on due to being shut off at the high pressure cut-off sensor. Unit turned on and slowly began to decrease in numbers again. With all this information I suspect a leak somewhere in the system. A leak test will need to be performed to further diagnose system.
Customer stated that their Coleman heat pump was installed about a year ago and is now not turning on. It has kicked the customer into Auxiliary Heat, however, the fan won't blow. Upon investigation, the technician found that the unit has a faulty condenser fan.
Customer stated that one of their air conditioning wasn't cooling the front of their office building. Upon investigation, the technician found that the thermostat was not securely connected to base plate which prohibited low voltage current from successfully transferring to desired call for cool or heat. I inspected unit for any issues and could not find any, issue was at thermostat and now has secure connection. If issue returns, recommend replacing thermostat since wiring has correct voltage. Test ran unit a few times with no problems. No other issues at this time.
Customer needed an unused, broken heat pump system removed from the property before selling the home. Our technician removed and discarded of the old heat pump unit.
Thermostat is displaying a red light and is not communicating with the outdoor sensor. We added an outdoor wireless sensor to work in conjunction with New Vision Pro 8000 thermostat
Customer states that the heat pump isn't working, there is a blinking green light but her ductless unit wont open and will not blow air. Customer is without heat.Unit was not operating upon arrival. Received an E6 air code indicating compressor not getting power and not coming on. Suspect bad circuit board and outdoor unit. I call Daikin to confirm findings. Daikin concurred with findings. There is a slight chance compressor may be bad as well. Will not be able to diagnose compressor with a faulty circuit board. Will need to replace the circuit board and continue diagnostic on unit. Please call office once you have received estimate via email to schedule repair.
After coming out to do maintenance, we determined that there were several issues with the air handler. We sent another technician out to do a Diagnostic and found no failures with any mechanical equipment associated with the EF or HP but did find that during the original installation of the HP, many years ago by a different company, they used a temperature sensing relay to control the heat strip back up heat and did not wire it up correctly meaning this system has never been setup properly from day one. We made the wiring adjustments needed for AUX heat to operate. Explained to home owner that the current setup is not the most efficient but will work. Seeing how there is no outdoor air sensor communicating with thermostat it would only operate off indoor temperature droop. Recommended adding a wireless outdoor air sensor to acheive the most energy efficient setup at which time they agreed with my recommendation and I installed the Honeywell wireless outdoor sensor.
-Conclusion: System is setup properly now. System is in good/proper working order.
Customer's HP is leaking. CM Heating installed a HP, had to uninstall it for some pre-existing water damage to be repaired, then we had to re-install the unit.
Now, the unit is leaking and causing the customer's laminate floors to buckle. Our technician found Re-piped condensate drain lines due to a leak in the piping connection. After completion performed a leak test. No farther leaks from condensate piping.
Recommend a water detection alarm.
All operations normal at this time.
CM heating performed a heat pump Diagnostic - Upon investigation, I found that the thermostat was not properly set for current equipment. The previous repairs of the replacement of the defrost board and outdoor sensor are still operational, I did move the sensor to the outside of the unit to better detect ambient air. I adjusted the following in the thermostat settings; 0170, 0350, and 0360. All of which have to do with current system set up. Tested unit in all operations, average temperature from supply vents is 97 degrees. All operations are normal at this time, recommend annual maintenance.
CM heating performed a heat pump diagnostic and Needed to reconnect the outdoor temperature sensor to the thermostat.
CM heating Performed maintenance on heat pump air hander unit. Check safety circuits, performance components, refrigerant level/pressure, and the proper operations of the unit. Install new air filter.
All operations normal at this time.
Customer recently purchased home and stated that the air wasn't very cold. Upon testing heat pump diagnostic determine refrigerant level was low about 16.4 oz. Performed electronic leak test no leaks were found, recharged system to manufacture specs. Due to system running low on refrigerant there could be possibilities that other components may have damage- the indoor unit TXV may have a restriction, the unit is not performing optimal at the moment. Due to age, unknown low refrigerant conditions and system running on low refrigerant recommend new unit or TXV replacement.
Customer stated that their heat pump was not working. Our technician found that the heat pump was not running upon arrival. I checked the components and found the contactor was fried. I replaced contactor and system started up. Cooling was running nominal. Heating does have an issue. There appears to be icing up after the service valve in liquid line. Pressures are reading low, there may be a restriction in the threaded adapter to the service valve (cannot repair today, would need to quote replacement). No other issues.
