Andrew has come to my house a number of times now to service my air-conditioning and heating units. He’s the most lovely young man. Professional, knowledgeable, the service was done in about 45 minutes and I always have peace of mind after he leaves knowing I’m going to be fine for the winter. He explains anything that’s wrong, that I need to do or any issues I may anticipate. Thank you Larry and Andrew Halpin and Jerry who also came and assisted.

We have been using X-treme Temp Heating and Cooling since purchasing our home in 2019. They have never failed to provide prompt, friendly service. Working with them is the closest you can get to having “family in the business” as they do, indeed, treat you like family. Would highly recommend!

Customer had a smell in the house. The burner turned on for 30 seconds then shut off. Found the blower motor was not turning on. Checked for power at the board. The relay clicks but no output power from the board to the motor. Jumped out the motor and it does start properly. Tied the blower motor wire directly into power to get the customer heat. The circuit board needs to be replaced. The supply houses are closed. We will call them on Monday.

The burner was running when arrived. Checked the oil flow, and transformer. The transformer is showing signs of getting weak. Recommend replacing in the future. Removed the nozzle assembly and found the nozzle all black with carbon on the on the end cone. Replaced the nozzle, started and tested.

Performed pm on oil furnace 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 7.9%o2 0ppm co 0 smoke Upon arrival customer stated the compression fitting at the oil filter was slightly leaking oil. Took the fitting apart and inspected it. Fitting looked good still but we did see a small amount of oil residue on the oil line. Also saw a small amount of oil coming from the bleeder screw on the filter canister. Put a small amount of pipe dope on the threads to help create a better seal. Sprinkled oil absorbing powder down and watched the fitting for the remainder of the maintenance. Fitting is not leaking oil any more.

Upon arrival unit was on and customer stated they had no heat to the downstairs area. Found the zone valve had 24v going to it and the end switch was closing causing the aquastat to send power to the circulator pump. Checked power at the aquastat and had 120v. Checked the circulator pump and found it had no voltage. Bypassed the aquastat and jumped the circulator pump and the pump turned on showing the aquastat is bad and not sending power. After getting customer authorization we replaced the old aquastat with a new one. Turned the unit on and the unit started working properly. Purged some air out of the basement zone. Started and tested the system. Had hot water coming back on the return for the lower section of the zone. When leaving boiler pressure was at 19psi

Inspected both furnaces and tested due to water in the basement. Both blower motors operated correctly and the burners started properly. There is evidence of water getting into both furnaces. Furnace closest to water line- -The circuit board appeared to get wet. - recommend replacing before premature failure. - Recommend removing the blower assembly and cleaning the floor of the furnace. - Recommend removing the insulation inside the blower compartment and replacing it. Furnace closest to the door- - The circuit board appeared to get wet, there are a couple of brown spots. - recommend replacing before premature failure. - Recommend removing the blower assembly and cleaning the floor of the furnace. - Recommend removing the insulation inside the blower compartment and inside the return plenum and replacing it.

Performed pm on oil boiler 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 While performing the maintenance we found 2 hi-vent that have corrosion on them showing they have leaked in the past and are no longer functioning properly. Found the oil shut off valve at the burner is not closing fully and is still leaking oil by to the strainer even when the valve is fully seated. Tested the autofeed and found it is not letting water through. Recommend replacing the oil shut off valve, 2 hi-vents, and autofeed and backflow combo.

Upon further investigation we found the hot water coil is not transferring the heat to the hot water. When the boiler was at 175 the water coming out of the hot water coil was only 140-150* F and was still dropping in temp. Took pictures of the boiler for a replacement quote. While performing the maintenance we found a bird in the chimney and saw high levels of soot. Recommend getting the chimney cleaned and inspected. Greg’s chimney 203 630 1976

The system was on and running when arrived. Checked the oil flow and transformer, both are ok. When the zones were calling for heat, the circulators were making a whooshing sound. Noticed the pressure gauge was reading 5 psi, lifted the handle on the automatic water feed and it added water to the system and stopped at 20 psi. With pressure in the system, the noise went away and temperature in the boiler started to drop. There was not enough water in the system to push the water to the 2nd floor. System is operating properly.
