Being new to the area we didn’t know who to contact. Once we found Xtreme Temp we were happy with the timeliness in scheduling. Larry was a great resource to understand potential issues and remedies to take to avoid further issues. He was very knowledgeable and able to explain how our system worked. Great experience. Thanks Larry

Performed an A/C pm. Blew out the drain line, replaced the air filters. Checked and tested the condensate pump. Rinsed the condenser. Checked the electrical connections, checked the pressures and temps. System was low on refrigerant, added 1 lb 2 oz R410a to the system System is operating properly.

Visually inspected indoor evap coil and blower compartment Checked all electrical connections and safeties Checked volts and amps Visually inspected air filter Rinsed condenser coil Blew out drain line and poured water to ensure properly draining Checked refrigerant levels Checked capacitor Took temps While performing the maintenance we found some low voltage wires chewed up by the condenser. Cut out the damaged section and reconnected the low voltage wires. Unit is working properly

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 5.8%o2 25ppm co 0 smoke While performing the maintenance we found the hi-vent on the boiler has been leaking in the past and has sediment buildup on the top. Would recommend replacing the hi-vent. Also when testing the autofeed we found it was continuing to add water to the system even when the system is up to pressure. Recommend replacing the autofeed. Valved the autofeed off for the meantime so the boiler does not get too much pressure.

Upon arrival unit was on but not running. We found the primary control was a newer becket Bluetooth control. Connected to the control with our phone and went through the run history of the unit. When scrolling through the history the control said it needed a software update to operate properly. Updated the software and started the unit. We found the ohms for the unit were getting progressively higher after each run cycle. Checked the nozzle and found it was dripping and had a dark spot forming showing it was spraying at the wrong pattern. Also found oil in the blast tube and some carbon buildup showing this had been happening for some time. Replaced the nozzle and cleaned up the oil residue and carbon. Started the system and performed a combustion test. Ohms before replacing the nozzle were roughly 800-1100. After replacing the nozzle the ohms dropped to 380. Unit is working properly. The unit resetting could have been caused by a combination of the nozzle going bad and the control s

Performed a heating pm on a Heat Pump system and a pm on an electric water heater. Checked the coils and air filter. Customer changes the filter. Blew out the drain. Checked the electrical components and pressures. Checked the capacitor rating-52/6 mfd. Checked the heating elements and amp draw 14 & 18 amps. 96* discharge with the heat pump, 112* with the heating elements. Checked the electrical wires , thermostats, and elements for the water heater. When checking the lower element, there was no power when adjusting the lower thermostat. Found the reset was tripped on the upper thermostat. Reset it and still no power to the lower. The upper thermostat is bad and needs to be replaced.
Larry H.
Checked the air handler, found the heating coil is leaking from the back corner on the bottom. The system is older. We will work up several different options, replace the coil, replace the system and install ball valves at the water heater.
Larry H.
The furnace was not off on reset. The primary control was blank. Checked for power to the furnace, there was 120 volts to the furnace and to the primary control. There was no power to the thermostat. The transformer inside the primary control is bad. Replaced the primary control. Started and tested several times.
Larry H.
Customer turned the thermostat up and the burner started. Checked the oil, flow and transformer, both are OK. Removed the nozzle assembly, and the nozzle was very dirty, which can disrupt the spray pattern and caused the burner to go off on reset. Replaced the nozzle, started and cycled several times. The system is operating properly.
Andrew H.
Installed (4) Wi-Fi Honeywell T6 thermostats. Programmed and connected them to the internet. Started and tested.

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 3 hi-vents that had been leaking in the past and had sediment buildup on them. Recommend replacing the hi-vents

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. 4.3% o2, 6 ppm, 85.7% efficient. System is operating properly. Performed a heating pm on a Fujitsu Ductless system. Washed the air filters. Blew out the drain line. Rinsed the condenser coil. Checked the electrical connections. Started and turned the system to full heat. checked the temps, pressures and amps. Compressor drawing 7.2 amps, rated for 10 in heating. 84* return/ 125* supply. 41* delta in heating. System is operating properly.

We will install a Taco Leak Breaker on the cold side of the water heater and repair the the leaks on the Hot side above the water heater. The Leak Breaker will shut off the cold water going to the water heater when water is detected on the floor near the water heater.
Larry H.
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. System is operating properly When arrived, the pressure in the boiler was down to 3-5 psi, which could cause the noise in the pipes. The valve going to the automatic water feed was off, turned the valve on and increased the pressure to 18 psi and the water pressure was still increasing. The automatic water feed is bad and needs to be replaced. There is a hi vent on the indirect water heater that has corrosion on it from leaking water. Recommend replacing the hi vents.

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 Inspected thermostat for the customer. Temperature variance was only 1.5 degrees which is acceptable. Thermostat is working properly
Larry H.
There was water under the return ductwork. Checked the humidifier and condensate pump. When the water was up to the point of the pump turning on, it was very slow pumping out. Blew out the drain line, it was not blocked. Checked the check valve. Tested the pump and it pump a little faster. When testing it again, it did not pump any water out. The condensate pump is bad.

A Goodman GMVC96 furnace in Wallingford was not providing adequate airflow. I diagnosed a failed ECM blower motor, causing the system to overheat and shut down. I replaced it with a new GE 5SME39 motor, adjusted fan speeds for optimal airflow, and tested the unit. The system is now running efficiently with proper air circulation.
Andrew H.
Removed the old 230 volt blower motor. Installed a new 230 volt blower motor and 7.5 capacitor. Started and tested the system for proper operation
Andrew H.
Upon arrival unit was off. Customer stated they tried cleaning the air filter earlier today when the furnace stopped working. Turned furnace on and turned the thermostat up. Found the furnace was blinking 4 times for a limit switch code. Turned power off to the unit to clear the code and checked the limit switch. We found the limit switch had continuity indicating it is still functioning properly and is not stuck open causing the code. Turned power back on to the system and the code cleared. Unit started up with no issue. Cycle the unit on and off multiple times with no issues. Could be an intermittent issue with the limit switch starting. Took pictures of the limit and the furnace model and serial number. If the issue happens again recommend replacing the limit switch. Would recommend having a maintenance done on the system
Larry H.
Checked the system. The noise was from the circulator, there was 0 psi on the boiler gauge. Added water to the boiler and the noise went away. Increased the pressure to 20 psi. Inspected the boiler, there is corrosion on the top of the boiler between sections 2 & 3. Inside the boiler there was a spot between sections 1 & 2 that has an area that is shiny from water. There is a little air in the system from when there was no pressure, the system can draw air in from any area that is compromised by a leak. The boiler needs to be replaced soon. The pressure will continue to decrease over time. Also gathered the information for replacement and an electric hot water heater.
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 6.2%o2 28 ppm co 0 smoke When arriving for the maintenance we found the boiler pressure was at 4 psi which is low. Last year we found the autofeed was leaking water into the boiler continuously and valved it off. Since the autofeed is valved off the boiler lost pressure through out the year. Opened the valve for the autofeed and brought system pressure back up to roughly 18. Had to close the valve for the autofeed again as it is still allowing water through when the system is up to pressure. We also found the pressure relief is still dripping water. Recommend replacing the autofeed and the pressure relief
Andrew H.
Drained pressure from the water coil. Cut out and removed old mixing valve. Installed new mixing valve and nearby piping. Removed old hi-vent and installed a new one. Filled system back up with water. Bled all zones of air. Started and tested the system and adjusted the mixing valve as needed. Had water temps around 120 consistently coming out of the mixing valve. Had hot water coming back for all 3 zones. When leaving boiler pressure was at 18psi
Larry H.
Ran a new condensate drain line from the condensate pump to the sewer line. Drilled and tapped a hole for a fitting. Started and tested the pump. Water flows properly.
Larry H.
Checked the water heater. The burner was not off on reset. Th aquastat control had power and there was a call for the burner. The aquastat was buzzing but was not sending power to the burner. The aquastat is bad and needs to be replaced. Replaced the aquastat. Started and tested
Larry H.
Turned the temp up and there was a buzz inside the air handler. The blower was not running. Found the capacitor was bad. Replaced the capacitor and the blower started properly. Checked the heating elements. 18.0/23.1 amps. Checked the pressures at the heat pump. The discharge temp with the heat pump was 97*F. The system is operating properly.
