Great service!

We couldn’t be more happy with the quality of work we received. The technician was extremely knowledgeable and was very honest about what he saw and gave suggestions long the way. You can tell that he genuinely cares about his job and wasn’t looking to “add more work” to charge more money. I fully trust the work done! Thank you for everything!

Fantastic Service

Larry came out to service my house for our to central AC units. One of them would not start. Larry identified the problem and came up with a solution that worked. Larry also cleaned both units for the season and noticed that some of the insulation on the duct work was torn, and so he fixed that too. Larry was friendly, clear with the work that needed to be done, and very knowledgeable. I would use X-Treme Temp again.

Checked system, the system is low on refrigerant. Added 1 lb 4 oz R22 to the system. 64*f supply/ 79*f return. System is operating properly. It is an older system. Recommend replacing due to an older R22 unit.

Checked the temperature at each thermostat. Each one is reading correctly. Checked the operation of the 3 zone dampers. The first floor zone is stuck in the open position. The damper needs to be replaced.

Raised the ductwork to straighten the coil. The ductwork and coil will need to be properly raised and secured. There is a small kink in the liquid line also. Turned the system on, the blower turned on but the condenser did not turn on. There is a section in the thermostat wire that needs to be repaired. Opened the electrical compartment and found a snake that shorted the compressor side of the capacitor. The capacitor needs to be replaced before checking the charge. Replaced the capacitor and repaired the wire. Started and checked the charge. Discharge temp-57*f. System is operating properly. Duct Diagnostic- 203-734 -1532

Customer turned the system on, the contactor pulled in and there was a buzzing sound but nothing started. Found the capacitor was bad. Replaced the capacitor, started and tested. The system is properly charged.

Upon arrival system was off. Customer stated that when they last ran the ac the copper lineset and condenser started to freeze up. Hooked up refrigerant gauges and turned the unit on. The condenser turned on but the indoor blower motor did not start. Checked the capacitor and it was good. Gave the blower wheel a push and the blower started to turn but then slowly came to a stop indicating the blower motor is bad. After getting customer authorization we replaced the indoor blower motor. Started and tested the system. Unit is working properly

Performed an A/C pm. Blew out the drain line, customer the air filter. Rinsed the condenser. Checked the electrical connections, tested the condenser in full load mode. checked the pressures and temps. 51*f supply air, 72*f return air. System is properly charged. System is operating properly.

Turned system on and checked. System did not turn on. Checked the condensate pump, it was not tripped. Installed the overflow switch in the secondary drain pan. There may have been a loose wire. Checked all wires. Started and tested. Adjusted the thermostat several times and the system turned on and off properly.

Upon arrival unit was turned off. Turned both zones on and the indoor blower started. Went outside and found the compressor was running but the fan motor was not. Opened the electrical compartment and found an old mouse nest. Inspected all wiring and found no chewed up wires. Tested the capacitor and found it was still good indicating the fan motor is bad. After getting customer authorization we removed the old fan motor and installed a replacement universal motor. Turned system on to check polarity of the motor. Hooked up refrigerant gauges and found the system had no pressure in it. Notified the customer and gave them the option of filling the system with a replacement refrigerant to get the system running for the immediate future or removing the new fan motor. Customer wanted the fan motor removed. Removed old fan motor and left the outdoor unit off. Running the system with no refrigerant will cause long term damage to the compressor. Customer did not want the fan motor reinstalled.

Customer turned the system on. Checked the pressures. The suction side was at 24 psi. The system is low on refrigerant. Customer wanted to add the refrigerant to the system. Added 2 lb R22, and brought the pressure up to 43 psi. Due to the system not fully charged, the system may not properly and possibly freeze the coil.

Checked both systems. The 1st floor system had no power. Found the breaker tripped. Reset the breaker and the condenser started. Checked the amps of the compressor, 7.5 amps. 1st floor system is operating properly. 2nd floor was not on cooling just fan. Set the remote to cooling and checked the charge, added 9 oz R22 to the system. 49*f discharge air.

Upon arrival unit was off. Turned unit on and it fired but was making a lot of noise. Saw water pooling around the base of the boiler and took the top of the boiler off to look for where the water was coming from. Found both seams of the boiler were leaking externally. Also looked into the boiler chamber and found the inside of the boiler had water in it. Opened up the boiler door and had water pour out from the combustion chamber. Water is leaking inside of the boiler and making it hard for the boiler to establish a flame. Left the burner and boiler off. Took pictures for a replacement quote.

Checked system. The air filter is clean and the system is on. Checked the charge, found the system is low on refrigerant. Added 3 lb 6 oz R410a to the system. 62* discharge and and still dropping. System is operating properly. Recommend having the system serviced yearly.

Checked system. There was no power to the thermostat. There is a condensate pump in the attic next to the unit. When arrived, the blower door was off and the pump was unplugged. Plugged the pump in and it was in alarm due to the tank was full. It pumped the water out properly and it came out of alarm. Checked all the low voltage wires. There is an overflow switch in the secondary pan. The overflow switch is not operating properly, there is no water in the pan and it’s breaking the circuit. The overflow switch needs to be replaced. Removed the wires for the overflow temporarily to get the system running. Checked the charge, the system is low on refrigerant. Added 15 oz R410a to the system. 60*f discharge air. The system is operating properly at this time. Need to order and return to replace the pan switch.

Upon arrival unit was turned off. Customer stated the unit was producing a lot of water from the air handler. Inspected evap coil and the air filter. Evap coil was clean but air filter was dirty. Replaced the air filter with a customer supplied one. Turned unit on and both indoor and outdoor units turned on. Checked the capacitor and it was good. Checked refrigerant levels and found the system was low on refrigerant. After getting customer authorization we added 1 lb 13 oz R22 to the system bringing the subcooling from 1 up to 10 which is within manufacturer’s specifications. Unit is working properly. Took pictures and measurements for a replacement quote.
