Awesome service and price!

X-treme Temp has been serving my house for many years. They are very professional and always provide awesome work. Before the scheduled time, I would receive notification that technicians are coming. After technicians(Andrew and Larry) arrive on time, they ask us if we have any questions. They wear booties to enter my house. During covid, they wear masks to make customers feel safe. Not only Andrew and Larry did the awesome service, they also found out a hidden controller which we could not find to turn on the humidifier. On top of that, they took time to answer our questions patiently. After the service, I received a receipt by email. I would strongly recommend this company to friends.

Customer turned the first floor thermostat on. Checked the boiler, did not hear the circulator turn on. Checked for power. Had 127 volts at the aquastat and at the circulator but it’s not turning on. The circulator is bad and needs to be replaced. Customer would like to replace the first floor thermostat also. While working on the circulator, noticed that the extrol tank was full. Recommended replacing while the system is draining. Drained the system and replaced the circulator and extrol tank. Filled the system and purged. Removed the thermostat and installed a Honeywell T4 thermostat. Started and tested.

Performed 2 ac pms Visually inspected indoor evap coil and blower compartment Checked all electrical connections and safeties Checked volts and amps Visually inspected air filter Replaced both filters with customer supplied Rinsed condenser coil Blew out drain line and poured water to ensure properly draining Tested condensate pump Checked refrigerant levels Checked capacitor Took temps While performing the maintenance we found the customer had the second floor system replaced since the last maintenance. We found the refrigerant line connections were made with silver solder instead of braze. Manufacturers say in the install manual not to use silver solder since it is not rated for higher pressure refrigerants. Also found the second floor unit was low on refrigerant. The manufacturer calls for 10*sub and the u it was only at 2.5*. After getting customer authorization we added 11oz R410A to the system bringing the subcooling up to 13*. Unit is working properly

Turned the system on, nothing turned on. Checked for power at the circuit board inside the furnace, there as no power. Started to remove the cover plate on the service switch at the furnace and the system turned on. Checked the wires on the switch, the power wire was not connected fully and came out of the terminal very easily. Secured the wires and tested. The switch did not turn the system on. The switch needs to be replaced. Replaced the service switch. Turned system on and checked the pressures and temps. The system is low on refrigerant. Added 6 oz R22. Turned the thermostat to heat and checked the operation.

A homeowner’s Bryant Evolution furnace in Cheshire was failing to ignite. The hot surface ignitor was cracked, and the flame sensor was covered in carbon buildup. I replaced the ignitor with a new Norton 271NM and cleaned the flame sensor. After resetting the control board, the furnace ignited without issues. The system is now running efficiently, providing consistent heat throughout the home.
