Excellent service, highly recommend!

Andrew was here to clean our furnace today, and as always did a fantastic job. He found a few minor things that needed replacing and showed me the parts. Also, after 30 years of boiling hot water, he said our mixing valve needed replacing, must of asked a dozen plumbers and furnace people over the years with no results. These people are the real deal, so happy we have them!
Excellent service, thank you Larry!

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. 6.1% o2, 25 ppm, 83.3% efficient System is operating properly.
Larry H.
Performed a heating pm on an oil furnace. Brushed and vacuumed. Replaced the oil filter, nozzle and strainer. Replaced the air filter, 16x25x1 Started and checked the safeties. Performed a combustion test. 7.9% o2, 33 ppm, 86.5% efficient System is operating properly. Performed an A/C pm. Blew out the drain line. Rinsed the condenser. Checked the electrical connections, checked the pressures and temps. System is operating properly. The capacitor is rated for 45/5 +/- 5% mfd, the actual was 44/1.4 mfd. The fan side is below the limits. Also the fan motor is drawing the max rated amps of 1.2 amps. The fan motor is very loud. Recommend replacing the condenser fan motor and capacitor. - the customer is turning off the system and wants to replace everything in the spring. The water heater is from 2015, recommend replacing. Customer has scheduled an appointment to replace the 40 gallon Electric hot water heater w/ a Taco Leak Breaker and pan.

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 9%o2 2ppm. O 0 smoke While performing the maintenance we found the firomatic oil valve handle was starting to go bad. The solder ring was starting to fall to the bottom of the handle. Attempted to thread on a new handle but found the stem of the oil valve was spinning freely. After getting customer authorization we replaced the oil shut off valve. Customer stated the hot water is very hot. Tested water temps coming out of the water coil and the mixing valve. The water temp coming out the mixing valve was only 2-5* colder than coming out of the water coil indicating the mix g valve is letting too much hot water through. Recommend replacing the mixing valve and moving it further away from the water coil. Manufacturers recommend having it at least 10 inches away due to high temps. 1/2 mixing valve

Performed a combustion test. System is operating properly. The furnace is older and the oil line goes into the floor at the tank and coms up by the furnace. Recommend replacing the line.

When arrived, the blower at the furnace was running. Checked the system and found the Fan Switch on the thermostat was turned on. Turned the switch off and the blower turned off. Set it to cool, the blower turns on but the condenser did not start. The contactor was pulled in and there was 247 volts at the unit. Checked the capacitor, found both sides of the capacitor are bad. The capacitor is the component that starts the compressor and the fan motor. The capacitor needs to be replaced. Replaced the capacitor, started and tested. System is operating properly, 56*F discharge air.

Removed old combustion chamber, gasket, and debris. Installed a new combustion chamber and gasket. Started the boiler and let it run for 25 minutes for the chamber and adhesive to cure. Perform combustion and smoke tests. Pressure relief: Drain pressure from the system. Remove old pressure relief and install new pressure relief. Fill system back up with water. Purge air from all zones. Start and test system for proper operation.

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 6.9%o2 0 ppm co 0 smoke While performing the maintenance we found the oil line is starting to corrode. Since the oil line is in the concrete the lime in the concrete is starting to oxidize the copper. Would recommend replacing the oil line in the near future. Also found the water heater is from 2014. Would recommend replacing that in the near future as well. Typically recommend replacing water heaters every 10 years. Had to cut the metal on the furnace where the oil line enters since we could not remove the strainer housing. Made the hole larger and now the strainer can be easily removed. Oil line is roughly 20 feet

After getting customer authorization we added 1 lb 410A to the upstairs unit While performing the maintenance for the main floor unit we found the capacitor was open internally and had gone bad. After getting customer authorization we replaced the 35/5 capacitor. Started the unit and found it was low on refrigerant. After getting customer authorization we adde 4.5 lb R410a to the downstairs unit. Also added UV dye to both systems. Units are working properly. Need to call and schedule leak search

Recovered the refrigerant from the old system. Removed old air handler, condenser, line set, thermostat wire and electrical whip. Installed a Trane XR14, 2 1/2 ton condenser and a Trane TEM6 variable speed air handler in the attic. Installed new condenser pad, line set, thermostat wire, and electrical whip. Brazed in all new refrigerant connections. Pressure tested and evacuated the system. Started the system and added addition refrigerant as needed. Had 79* return air and 61* supply air.

Upon arrival unit was off on reset. Went to check for oil flow when we found the firomatic handle’s lead ring had failed and dropped causing the oil shut off valve to close. Removed the old firomatic handle and replaced it with a new one. Checked for oil flow and had good and clean flow. Checked the nozzle and had no dripping in the blast tube. Checked the past run history from the primary control and found the system was running great until the handle failed. Started and tested the system. Unit was running at 4.7%o2 3pp co 0 smoke with 160 ohms. Unit is working great.
