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.
Great service

When we had a problem with one zone of our heating system, X-Treme Temp worked with the problem until it was solved. We are most appreciative.

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
john - Cheshire, CT 06410
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).
Great service!

Someone was sent over the same day that I called the office!

When arrived, turned the heat on but the burner did not turn on, just the blower. Checked for power at the zone panel and to the circuit board. Checked the high limit- which is good. There was no 120v going to the burner from the circuit board. Moved the molex plug on the circuit board and saw an arc on the board and the burner started. The circuit board needs to be replaced before it fails. Performed a heating pm on an oil furnace. Brushed and vacuumed. Replaced the oil filter, nozzle and strainer. Washed the air filter. Started and checked the safeties. Performed a combustion test. System is operating properly.

Checked condenser. Moved wires. All the wires are secure. Check the contactor, which is new. There is a time delay wired into the contactor which is original. The time delay may have stuck and when customer tap the unit, the time delay, engaged, and set power to the contactor. Disconnected the wires for the time delay. The customer mentioned that the system has been running for a while. Checked the pressures and the system is low on refrigerant. Added 1LB 11 oz R-410a to the system.

Upon arrival customer stated they just got back from vacation and found water around the furnace. Found some droplets coming from the back of the furnace by the humidifier. Saw that the humidifier was turned off and had no water flowing to it. Tested drain line for the ac and it was working properly. Upon inspection found the condenser coil was very dirty. After getting customer approval we chemically cleaned the condenser coil due to a high level of dirt and debris. Checked refrigerant levels and found the system was slightly low on refrigerant. After getting customer approval we added 1 lb R22 to bring the system back up to proper levels. Took pictures and measurements for a replacement quote.

Upon arrival unit was off. Customer stated the secondary pan had filled with water and the unit was working intermittently. Upon inspection found the trap for the drain line was leaking and causing the secondary pan to fill with water and trip the float switch. Replaced the trap and poured water down the drain to test it. Drain is working properly with no leaks. Started unit and checked refrigerant level. Found the system was slightly low on refrigerant. After getting customer authorization we chemically cleaned the condenser coil due to a high level of dirt and debris buildup causing the system to have higher pressures. Added 10 oz R410A to the system. Unit is working properly.
Andrew H.
Upon arrival unit was off. Customer stated the condenser was running independently of the air handler. Turned thermostat on and both air handler and condenser turned on. Inspected air handler and all wiring and connections were good. Inspected condenser and found small section of tstat wire was bare and rubbing each other and touching metal which could have made the condenser run without a call for AC. Cut broken section out and wire nutted the wire back together. Checked refrigerant levels and found the system was slightly low on refrigerant. After getting customer approval we added 2 lbs R410A and UV dye to the system. Also found the liquid line port was corroded and slightly cross threaded. Need to return to preform leak search and try to correct the threads on the liquid line port.

Upon arrival I found a good sized puddle of oil underneath the oil tank. I applied speedy dry and found the leak. A Little pin hole under the tank. I put a temporary tank patch on which seemed to hav stop/slowed the leak. Gave customers an estimate to have the oil tank and oil line replaced.

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
Larry H.
Performed heating maintenance on an oil boiler. Flushed in fact, replaced strainer and nozzle. There is no oil filter at the tank. Recommend installing one. Checked safeties and electrical connections. Adjusted electrodes. Started and performed a combustion test. 6.3% O2, 17 ppm Co, 82.7% efficient,0 Smoke. The boiler is operating properly. Checked the indirect water heater. The coil gasket is leaking. This is the 3rd indirect that the customer has had. We need to call the contact number that the customer gave us.
Dyllan M.
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.
Larry H.
Removed and replaced the furnace control board. Started and checked the operation of the burner, fan and limits. System is operating properly.
Dyllan M.
Performed a heating maintenance. Oil furnace. Changed the nozzle filter and strainer. Cleaned the heat exchanger and flue pipe. Inspected electrical. Adjusted electrodes. Bled the oil line. Started and tested. Combustion test was 28ppm. I had a spike in the o2 when the blower turned on. Upon further investigation I found the screws around the gaskets for the furnace were loose. Once I tightened them the o2 leveled out. No smoke on the smoke test.
Larry H.
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.
Dyllan M.
Removed and replaced the heat exchanger inside the oil furnace. Started and burned off the oil residue on the heat exchanger when shipped from the factory. Performed a combustion test, 7.1% O2, 34PPM CO, zero smoke. System is operating properly.
Larry H.
Replaced the furnace control board. Turn system on and checked operation. Turned the thermostat off to make sure the burner and blower turn off properly. Turned the temperature back up and everything operates properly.
