Awesome service and price!




Review of X-Treme Temp Heating & Cooling, LLC

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.

Review of X-Treme Temp Heating & Cooling, LLC

Dyllan and John from X-treme just left after completing an evaporator coil replacement. I was extremely (no pun intended) impressed with their professionalism, cleanliness and knowledge. I've found it rare to experience this level of service and I tend to be a hard marker. Cost: The cost was fair. Its a little difficult in this economic market to really know gauge the cost. However I will say that I will without hesitation call on X-treme for any A/C issues. I also plan on using them for my heating as well.

First Time New Customer with NON Functional A/C




Review of X-Treme Temp Heating & Cooling, LLC

We are a new customer with X-Treme. Our A/C had no cooling capability. The technician (Andrew) arrived on time, was very professional. He checked the complete system for general condition. Our system clearly has a leak somewhere. He injected a UV tracer dye into the system and added refrigerant. We are happy we are getting cold air again but we have to wait for the dye to leak out enough to detect the leak. So we are not over but have a good start. I didn't rate the cost as I have no idea what is low or high. My guess the price was fair (as in reasonable).

Upon arrival disassembled blower housing and removed old blower wheel. Since the wheel was removed we cleaned all dust and debris from the inside of the the blower housing. Installed new blower wheel and mounted it to the motor. Had to drill new holes for the motor to mount properly because one screw hole had been stripped due to vibration. Mounted the motor and wheel and reassembled the blower housing. Started and tested the unit. Unit is now working properly.

Boiler Repair - Customer stated that the low water cutoff had been short cycling the boiler. Upon investigation found that the well for the low water cutoff had been leaking into the device causing corrosion on the control board and the relay. Bypassed the low water cutoff temporarily so the boiler can still run for heat. Took pictures of the part and will need to return to replace it. Pressure was at 21psi when leaving

Found the oil pump seal was bad and was slowly leaking oil. There was a small puddle of oil under the burner that seemed to have made its way into the blower compartment which is most likely causing the smell coming out of The vents. I cleaned up as much of the oil as I could and put down oil absorbent powder. Replaced the oil pump. Adjusted pumps pressure to 130psi. Started and tested. Burner was reading 180ohms. Combustion test was 18ppm at 7.8%o2. No oil leaks found. Applied new furnace cement to the flue pipe.

When arrived, the first floor furnace was off on reset. Reset the burner and it did not light, checked the oil flow and transformer. Both were OK. Replaced the nozzle burner started properly, cycled several times and burned off access oil in the chamber. The system is operating properly at this time. Recommend installing a 10 micron spin-on oil filter at the 1st floor furnace. The first floor furnace has a small nozzle size which can plug up very easily.

Performed a heating maintenance. Oil furnace. Changed the nozzle, filter and the strainer. Cleaned the heat exchanger and flue pipe. Purged the oil line. Adjusted electrodes.
