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.

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 5.9%o2 35ppm co 0 smoke
Larry H.
The furnace was running when arrived. Checked the oil flow and transformer, both ok. Removed the nozzle assembly and the tip of the nozzle was black and there was carbon on the end cone. Cleaned the nozzle assembly and replaced the nozzle. Started and tested. The furnace is operating properly. Recommend having the the furnace and water heater serviced.

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 3.0%o2 30ppm co 0 smoke When arriving we noticed the boiler pressure gauge was reading 50psi. Isolated the boiler and drained all pressure from the boiler. When the boiler was empty the pressure gauge was reading 30psi. After getting customer authorization we removed the old pressure gauge and installed a new one. Filled the system back up with water and purged all zones of air. Started and tested the system. Had hot water coming back on all returns. System is working properly. When leaving boiler pressure was at 22psi
Larry H.
Water was coming from the pressure relief valve. Checked the system. With the system running the pressure stayed constant at 15 psi. Checked the extrol tank. At this time there is no water migrating into the air side., but it doesn’t have the normal hollow sound on the air side. The pressure relief valve is bad and needs to be replaced. Replaced the pressure relief valve is bad, after filling the system back up, the automatic water feed did not stop adding waster to the system. Turned the valve off to the water feed. In the future, the automatic water feed will need to be replaced.
Andrew H.
Upon arrival customer stated they have issues with the water staying hot when the shower is running. Turned on the shower and checked water temps. Found the water temp decreased significantly after a period of time. Checked voltages at the water heater upper and lower elements and thermostats. Found the lower limit is not receiving power and is not turning on. Both heating elements have continuity indicating both elements are still good. Took pictures of the water heater to order the replacement part.

Water heater was off on reset. Reset the control and after a couple of seconds, the burner lit. Checked the oil flow, there was air at the pump. Checked the oil filter at the tank. The filter was dirty, causing the water heater to suck air when both the furnace and the water heater are running at the same time. Replaced the oil filter and bled the line for the furnace and water heater. The water heater is working properly.

1) Drained the pressure from the boiler and replace the Pressure Relief Valve. Fill and check for leaks. 2) Removed and installed a new Chamber Kit inside the boiler. 3)Installed a new Tigerloop (de-aerator) and oil lines at the burner. Started and ran the boiler for a least 20 minutes to help the new chamber cure. Performed a combustion test. System is operating properly.

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. 7.1% o2, 0 ppm, 80.5% efficient System is operating properly. While performing the maintenance, noticed water is on the air side of the diagram in the extol tank and when the boiler was cold the pressure was at 10 psi and increased to 28 psi when the boiler heated up. Recommend replacing the extol tank before the pressure relief valve starts leaking. Removed and replaced the extrol tank. Filled and purged the system.
Andrew H.
Customer stated they had a wet sock smell coming from the downstairs unit when they were switching between heat and cooling. Checked the evap coil and it was clean with now buildup. Checked the air filter and found it was slightly dirty. Replaced the air filter. Went through the run cycles and error codes on the Trane thermostat. Found the system was cycling on and off properly and that there were no error codes for the systems operation. Checked temp output in normal heating and with the electric heat. Had a 17.5* temp difference (typically between 15*-20*) in normal heating and a 24* temp difference with the electric heat. Unit is working properly. Recommend getting maintenance done on both systems in the spring time. Wet sock smell can be caused by algae growth on the evap coil or drain pan, a dirty or plugged air filter, a clogged drain line, or stagnant water. Another cause could be the electric heat strip burning off any dust when operating for the first few heating cycles. Did

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
