Andrew did a great job of explaining his findings. My furnace is 23 years old and while it is starting to show it’s age, there was no pressure, or hard sell on a replacement unit. Andrew was courteous, professional, knowledgeable, and a dog lover!

From the moment Andrew arrived. He was very personable and respectful. He did a very thorough job looking at my heat pump unit, was very clear in the explanation of what was wrong. Even brought me up into the attic to have a look for myself, so I could even better understand and walk me through the next steps is definitely an asset to xtreme temp.

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 7.4%o2 2ppm co 0 smoke While performing the maintenance we found the combustion chamber is starting to crack and show signs of wear. Recommend replacing in the future. Also saw a hi-vent above the boiler had been leaking in the past but had sealed itself shut again. While bleeding the oil line before testing the boiler we noticed the oil pump solenoid valve was starting to leak oil. The overhead oil line could be the cause of it leaking due to the oil pump having to work harder with an overhead oil line and with pockets of air causing the seal to start to dry out. Recommend installing a tiger loop to lessen the stress on the oil pump and burner motor. After getting customer authorization we replaced the oil pump. Started and tested it and dialed in the fuel pump pressure. Unit is working properly
Larry H.
Checked system, and the circulator was very hot. Turn system off to check if the system was air bound or if the circulator was bad. While adding water to purge, notice water on the floor. Water was coming from the bottom of the boiler. Looked inside the chamber and between sections 2 & 3, water was coming out and filling the chamber. Turned water off and disabled the circulator and burner. The boiler needs to be replaced. The office will work up a price and get back to the customer.

The burner was off on reset when arrived. Checked oil flow and there was very little oil coming out at the pump. Checked the oil tank and found the firematic handle on the tank valve failed and closed the valve. Replaced the handle and bled the oil line. Good oil flow. System is operating properly.

Replaced the pressure relief valve and filled the system. Noticed the hi-vent also leaking and replaced. Purged the 2 zones. Started the pilot flame and turned the switch on for the boiler. Checked the circulation of the water. The autofeed is leaking by, shut the incoming water valve off. The packing nut for the autofeed isolation valve was leaking. Tightened the nut. If the valve continues to leak, recommend replacing the valve and the autofeed.

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 4.8%o2 4ppm co 0 smoke While performing the maintenance fund that the burner coupling was not snug and was starting to slip.

Started and tested and unit is working properly.

When arrived, the pressure relief valve was leaking. The pressure was at 20 psi. Tapped on the extrol tank and it sounded empty. Replaced the pressure relief valve and purged the air from the system. After purging and checking the system, the pressure was still increasing. Isolated the auto feed to make sure it wasn’t leaking by. Auto feed is good. Isolated the domestic side of the indirect and the domestic is not leaking by. Purge the system again and the is no air but the pressure keeps increasing. Replaced the extrol tank and the pressure stabilized at 20 psi with no more issues.

Pumped refrigerant down into the condenser. Cut out and removed the old evaporator coil. Installed new evaporator coil and new drain pan. Brazed all new connections and pressure tested the system. Pulled a vacuum on the lineset and then released the charge from the condenser. Started and tested the system. Unit is working properly. Pressures were 116/285 with 14 degree sub cooling.

Customer turned the system on and the compressor did not start and there was a delay before the fan started. Checked the capacitors for both the fan and compressor, which are both ok. Found a power wire that goes to both capacitors burnt and broken. Ohmed out the compressor. The compressor is ok. Replaced the wire and connections. Started and checked operation.

Customer turned the system on and the condenser started. The compressor turned on but the condenser fan did not. Checked the capacitor and the capacitor is bad. Need to replace. Also there is a section of the thermostat wire outside that is bare and also needs to be replaced. Replaced the capacitor and replaced a section of thermostat wire at the condenser. Started and tested.

Upon arrival unit was off. Turned unit on and indoor unit turned on but the condenser didn’t. Upon inspection found the capacitor was bad on both legs and was not putting out any power. After getting customer approval we replaced the capacitor. Started and tested the unit. Refrigerant levels were good and within manufacturers specs. Had 76 return air and 58 supply air. Unit is working properly
Andrew H.
Upon arrival unit was off. Turned unit on and air handler turned on but no condenser. Upon inspection found the system had no pressure in it. Added nitrogen and found the refrigerant had leaked where the lineset enters the house. Cut and removed leaking section of lineset. Installed new section of lineset and coupled it to the existing. Performed pressure test and pulled a vacuum on the lineset to remove any possible contamination. Started and tested system and added required refrigerant. Unit is working properly

We found a mouse nest and multiple chewed wires for the low voltage. Cut and removed damaged sections and made new connections.
Larry H.
Remove and install a new wire harness inside the Mitsubishi Evap Unit. Also, we will go into the attic and reconnect the wires inside the branch box. Start and test the system. The bedroom unit starts properly, 53* discharge. The louvres are not moving up and down like they should. The motor and/ or lower board may need to be replaced. The customer does not want to do those at this time Checked the boiler. The extrol tank is ok. Replaced the pressure relief valve and purged the system. There was a little air in the system which can increase the pressure in the boiler high enough for the pressure relief to start dripping.
