The heat is stressing everyone's systems right now and Xtreme was able to fit me in first thing Monday after a Friday call, which was incredible. Larry showed up right on time and was as professional and personable as he always is. I wouldn't have anyone else service our ACs... Everything is working great, now!!

Andrew H.
Upon arrival unit was off. Turned unit on and the indoor unit and condenser fan turned on but no compressor. Upon further investigation we found the compressor side of the capacitor was shorted internally. After getting customer authorization we replaced the capacitor. Checked the air filter and the evap coil. Found the filter was a horsehair filter and the evap coil was very dirty. Replaced the filter with a pleated filter and performed a chemical clean on the evaporator coil. We do not recommend horsehair style filters as they allow most particles in the air through and lead to the evap coil getting dirty faster. Rinsed the condenser coil with water to remove light debris buildup. Started and tested the unit. Unit is working properly.
Larry H.
Found the boiler plugged, causing the black smoke. Shut Boiler off to clean. 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.
Andrew H.
Upon arrival searched evaporator coil for UV dye. Found multiple spots with UV die on the evaporator coil. Also saw some traces where the line set was silver soldered. went outside and inspected the condenser and found no traces of UV dye. Took pictures and measurements for a replacement quote.checked refrigerant levels before leaving and had 13.2 subcooling
Larry H.
Replace the primary control and aquastat at the boiler. Replaced the transformer inside the zone panel. Started and tested all zones and burner operation. System is operating properly.
Larry H.
Performed an A/C pm on the system. Replaced the air filter. Blew out the drain line and tested the condensate pump. Rinsed the condenser coil. Checked the electrical connections, pressures and temperatures. System is operating properly. The system is older. R-22 When replacing the air filter, found the Flo-check (check valve) for the heating coil leaking by and letting hot water go into the coil at the air handler. Closed the valve. The Flo-check needs to be replaced. Cleaned a large amount of fur and dust from the bottom of the return plenum. Recommend having the ductwork cleaned.
Andrew H.
Upon arrival unit was on. Inspected air filter and found the filter was plugged and was a reusable filter. Removed the reusable filter and replaced it with a pleated air filter. We do not recommend using this style reusable filter due to it allowing more particles past than a pleated air filter and can cause the evap coil to get dirty. Opened up the inspection hole for the evap coil and saw the drain pan was overflowing and causing water to drip down the furnace. Lifted the drain line and found a large amount of algae and buildup that was blocking the drain line from draining properly. Also found that the drain line was resting on the bottom of the condensate pump pan which was limiting the amount of water that could exit. Took apart the condensate pump and cleaned out the algae from the pump pan. Attempted to cut the drain line higher going into the condensate pump when we found none of the drain line fittings had ever been primed or glued. Took apart all drain line fittings and pipe.
Larry H.
The customer experienced a power surge yesterday. Checked boiler system. There was no lights lite up on the zone panel or the aquastat. Checked for voltage, had 124 volts. There was no 24 volts on the zone panel. The transformer in the panel is bad. Jumped out the circulators to test. All the circulators are ok. Opened the aquastat, to check for power. There was 124 volts but no 24 volts. The internal transformer is bad. Checked the primary control. There was 124 volts to the control but no 24 volts at the low voltage terminals. Jumped out the Ignition Transformer and Burner Motor to check the operation. Both are ok. The zone panel transformer, aquastat and primary control need to be replaced.
Larry H.
Customer had someone come out and jump the power for the fan motor. The circuit board is bad and needs to be replaced. Customer order board. Installed the customer supplied board. Started and tested.
Andrew H.
Upon arrival unit was off. Customer stated the outdoor unit was not turning on, but the indoor unit was and that there was a mouse nest in the condenser electrical compartment. Inspected the condenser electrical compartment and saw no chewed up wires. Tested the capacitor and capacitor was still Within factory specifications. Saw that wind speed terminal was slightly loose and we replaced it to get a better connection started and tested the unit and both units turned on check refrigerant levels and found the system was low on Refrigerant. After getting customer authorization we added 10 oz R22 to the system bringing the superheat from 45 to 20 which is acceptable. Had a 9 degree delta when showing up and a 16.5 degree delta when leaving.
Larry H.
Replaced the Fan Time Delay Relay. Started and checked the operation. System is operating properly.
Andrew H.
Upon arrival customer stated the ac is having a hard time keeping up. Checked air filter and found it was dirty. Replaced it with customer supplied. Started and tested the system and found it was low on refrigerant. After getting customer authorization we added 2 lbs 12 oz R410A to the system bringing the subcooling from 2 up to 13 which is within manufacturer’s specifications. Unit is working properly
Andrew H.
Upon arrival found the drain line was plugged and was not letting water get to the condensate pump. Removed the pvc plug from in front of the evap coil drain pan to drain water from the drain pan. Blew out the drain line going into the evap drain pan and cut the back side of the drain line. Blew toward the coil and blew out going towards the condensate pump which is where the blockage was. Installed a pvc union to make clearing the drain line easier and started and tested the system. Unit was draining properly when leaving.
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. 3.7% o2, 6 ppm, 85.7% efficient System is operating properly.
Larry H.
Turned the thermostat on and air handler did not turn on. Checked the breakers. They are all on and not tripped. Checked the air handler. Found the control voltage fuse was tripped inside the air handler. Replaced the fuse and the system started properly. Cycled and the A/C is working properly. 60* discharge air and still dropping.
Andrew H.
Recovered the refrigerant from the old system. Installed a new Trane TAMX, 2 ton air handler with a Honeywell Media Filter and a Trane XV18, 2 ton variable speed condenser. Started and tested system. System is operating properly.
Andrew H.
Upon arrival unit was on and running. While the unit was running we heard the condenser turning on and off. Went outside and checked the refrigerant levels. While the unit was running the pressures were fine when the high side pressure started to spike. This indicates the txv metering device is getting stuck closed and is causing the spike in refrigerant pressure. Need to return to replace the txv.
Andrew H.
Upon arrival unit was on but not running. Turned both thermostats down and unit did not click on. Upon further inspection we found the first floòr thermostat was not seated on the wall completely and was only making partial contact. With the first floor thermostat being the master thermostat it was causing issues with the 2nd floor thermostat entering and exiting cooling mode. Tested both thermostats individually and together and it was working correctly. Checked refrigerant levels and they were within the manufacturer’s specifications. Unit is working properly.
Andrew H.
Upon arrival unit was on. Checked air filter and evap coil and both were clean. Checked the condenser coil and found it was starting to get dirty. Rinsed the condenser coil of dirt and debris. Tested the unit and checked the refrigerant levels. We also found there was a mouse nest inside the electrical compartment. We found one partially chewed wire for the low voltage. Removed the chewed wire and reconnected the wire. Refrigerant levels were within manufacturer’s specifications. Upon further investigation we found the ductwork was poorly designed and is causing issues with airflow around the house. Took pictures and measurements for a quote to redesign the ductwork and check the sizing of the unit.
Larry H.
Turned the system on and checked the furnace. The blower was running. There was no air filter installed. It is an Aprilaire 5000 air cleaner. Checked the condenser. The fan was running but no compressor. Ohmed out the compressor and found one leg open. Removed the top and checked the wires. Found a terminal on the compressor broken. Repaired the wire and started. Checked the refrigerant levels. The system is R22. 58*f discharge air. Installed a 16x25x1 air filter. Recommend installing the proper size.
Larry H.
Checked the system. Unit was low on charge. Added 11 oz R410a to the system. Checked the operation of both dampers. They work properly. Recommend installing a Discharge Air Sensor in the ductwork. System is operating properly.
Andrew H.
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 Tested condensate pump Checked refrigerant levels Checked capacitor Took temps
Andrew H.
Upon arrival turned system off. Pumped some refrigerant back into the condenser and recovered all remaining refrigerant from the system. Removed the old txv and installed a new txv. Performed a pressure test on the system and then pulled a vacuum on the lineset. Released the refrigerant from the condenser and started the system. Tested the system and added refrigerant until the pressures and subcooling were within the manufacturer’s specifications. Unit is working properly with 11* subcooling and a 17* delta between the supply and return.
Andrew H.
Upon arrival unit was on. Checked refrigerant levels and found the system was low. After getting customer authorization we added Uv dye and 1 lb 11oz R410A to the system bringing the pressures back up to manufacturer’s specifications. Unit is working properly. Need to schedule a leak search to find the leak in the system.
Andrew H.
Upon arrival unit was off. Checked air filters and the coil. The air filter upstairs was a horsehair filter that does not filter much out of the air and we do not recommend this style. Coil was not dirty but the air filter was stating to get dirty. Replaced the air filter with a pleated air filter. Checked the condenser coil and found it was starting to get plugged. When the condenser coil starts to get plugged it can’t transfer heat from inside the house and will significantly impact the performance of the unit. Rinsed the condenser coil and then started the unit. The refrigerant pressures went from 175/378 down to 166/365 after rinsing the condenser. Unit is working properly. Refrigerant levels were within manufacturer’s specifications. Had 12.3* subcooling
Larry H.
Checked system. The condenser coil was plugged. The deck that is next to the unit was just sanded and sucked up the dust. Washed the condenser coil. Checked the pressures. The system is probably charged. The system was working harder with the coil dirty. Checked the evap coil. The coil is still clean.
