We have had X-treme Heating and Cooling for five years. In that time they replaced our A/C and have provided service of both our heating and cooling systems. They are a family owned business that go above and beyond. They have treated us as if we are family and are honest, reliable, trustworthy and pleasant.

Performed a heating pm on an oil boiler. Brushed and vacuumed. Replaced the oil filter, nozzle and strainer. Started and checked the safeties. Performed a combustion test. 6.3% o3, 0 ppm, 80.7% efficient System is operating properly. The corrosion between the sections is approximately the same size as last year. The oil line has been moved to over head. Recommend installing a Tiger Loop at the boiler to help remove any air in the line.

Upon arrival unit was on and running. Watched the unit cycle on and off multiple times. When watching it cycle we saw the boiler was shutting off at 140*. Upon further investigation we found the outdoor temp sensor was reading 77* outside when the real temp was less than 20. Undid the wires for the outdoor temp sensor and the unit started heating up to 180*. Unit is working properly. Need to replace the outdoor temp sensor.
Andrew H.
Upon arrival unit was on and running. Checked all zone valves and they were all opening up properly. Checked baseboards on the main floor and found the beginning of the loop was hot but no hot water was making it to the living room baseboard section. Found there was a pocket of air that was stopping the water from going all the way through the zone. Drained pressure from the system. Removed old autofeed and backflow combo. Installed a new autofeed and backflow combo. Filled system back up with water and purged all zones of air. Started and tested the system. Had hot water coming back on all 3 zones. When leaving system pressure was at 22psi

When arrived, there was some oil on the floor near the oil filter canister. When the customer was trying to change the oil filter, the tank valve was not fully seated. Closed the valve and changed the filter, customer supplied. Checked the canister and found the canister was leaking on the side. Replaced the bottom half of the oil filter canister and checked for leaks. Put some odor kill on the floor near the tank.

Upon arrival bled oil line of all air. Started and tested the system. Performed combustion test. 6.4%o2 80ppm co 0 smoke
Andrew H.
Brushed and vacuumed flue pipe and heat exchanger Replaced oil filter, nozzle, and strainer Checked all electrical connections and safeties Performed combustion and smoke tests 5.4%o2 45ppm co 0 smoke While performing the maintenance we found the condition of the combustion chamber had gotten worse. The sides have peeled off of the boiler wall more and back of the chamber has slightly more cracking. Recommend replacing the chamber before it collapses inwards and blocks the path of the flame. Also saw the pressure relief was dripping water. The boiler pressure was at 20 psi throughout the entire maintenance with no fluctuations indicating the expansion tank is still good. Recommend replacing the pressure relief valve. Also saw some minor corrosion starting to form on the oil line by the oil tank. Recommend replacing it in the future.
Andrew H.
Brushed and vacuumed flue pipe and heat exchanger Replaced oil filter, nozzle, and strainer Checked all electrical connections and safeties While performing the maintenance we found corrosion forming around the hot water coil on the boiler and places where the gasket is starting to get thin. Also found the combustion chamber is starting to peel off of the back wall of the boiler which will start to impact the performance of the unit. Due to the age and condition of the boiler we recommend replacing the boiler sometime in the near future. After cleaning the boiler we attempted to bleed the oil line and start the unit but found there was no oil in the oil tank. After getting customer authorization we added sludge additive to the oil tank. Need to return tomorrow to bleed the oil line, start the boiler and perform a combustion test on the boiler to ensure it is running safely. Left the boiler switch off. Travel charge to start the boiler will be $45.00 plus tax

Brushed and vacuumed flue pipe and heat exchanger Replaced oil filter, nozzle, and strainer Checked all electrical connections and safeties Performed combustion and smoke tests Drained pressure from the system. Removed hot water coil plate and gasket. Scraped the face of the boiler and the plate to remove the old gasket. Installed new hot water coil gasket. Filled system back up with water and purged air from both zones. Unit is working properly. When leaving boiler pressure was 20 psi.

Upon arrival unit was turned off. Customer stated the heat and the fan run continuously. Upon further investigation we found the burner primary control and igniter combo was bad internally and was still turning on even when there was no call for heat and with the tt wires disconnected. Also found 5th at the molex plug that attaches to the board was slightly loose and was causing the fan to run continuously. Removed the primary control and igniter combo. Installed a 4x4 box on the burner, mounted a new primary control, and installed an igniter. Started and tested the system. Unit is working properly now. Performed a combustion test and found when the blower turns on there is a spike in the o2 levels indicating a crack in the heat exchanger. O2 levels went from 2.1%o2 up to 2.9%o2. Took pictures and measurements for a replacement quote.

Performed a combustion test. 8.2% o2, 0 ppm, 83.5% efficient System is operating properly. There was some dryer lint stuck to the prong of the transformer and on the nozzle assembly, showed the customer. The customer needs to check the dryer vent connections. There is also a hi-vent on top of the boiler that is showing some corrosion from a previous leak.

Upon arrival customer stated they saw a hi-vent leaking slightly the other day but it had stopped. Saw another hi-vent with very minor corrosion starting to form. After getting customer authorization we drained the pressure from the system and replaced the 2 hi-vents. When trying to fill the system up with water we found the autofeed was plugged internally and was not letting water by. Removed the old autofeed and installed a new autofeed. Filled the system back up with water and purged air out of all 3 zones. Started and tested the system. Unit is working properly. When leaving the boiler pressure was at 20 psi

Cut out and removed old vent piping. Blew out the old oil line and removed it. Installed new vent piping to bring it up to code. Installed new coated oil line. Bleed air out of the new oil line. Started and tested the system.
Andrew H.
Upon arrival unit was on. Pressure was at 32 psi and the pressure relief was dripping. Drained some pressure from the boiler with the autofeed valved off and the pressure immediately went back up to over 30 indicating the expansion tank had gone bad. After getting customer authorization we drained pressure from the system and removed the old expansion tank and pressure relief valve. Installed new expansion tank and pressure relief valve. Filled the system back up with water and bled all zones of air. Started and tested the system. Unit is working properly. When leaving boiler pressure was at 20 psi Need to return at some point to replace the autofeed. After replacing the expansion tank and pressure relief we brought the pressure up to 15 psi but the autofeed continued to add water even when the system didn’t need it.

Performed a heating pm on an oil boiler. Brushed and vacuumed. Replaced the oil filter, nozzle and strainer. Started and checked the safeties. Performed a combustion test. 3.1% o2, 0 ppm, 87.2% efficient System is operating properly. There was air in oil line when starting it up. The line goes overhead. The fuel pump is starting to get stressed. Recommend installing a tiger loop. 3 systems- total 739.14
Andrew H.
Upon arrival unit was on and running. Customer stated the upstairs zone was not receiving heat. Checked all zone valves and found the zone valve for the upstairs zone was receiving power but was not opening. Replaced the zone valve and tested the heat on that zone. The heat in that zone is working now but we found there was some air in the lines. The autofeed is not letting enough pressure through to bleed the zones of air. Recommend replacing the autofeed so we can remove the air from the heating loops. Also recommend replacing the hi-vent on the boiler and the circulator gaskets due to corrosion.
