Smart Thermostat Installation
Christopher - Wallingford, CT 06492
Needed a common wire installed to one thermostat and another installed and the both wired in correctly. He got the job done, was polite and professional. However, he told me it would be $307. for the work before starting. After it was finished he told me it took him longer so they charged me $360.86 Ok that’s fine, “nothing crazy”. I also explained I need the boiler serviced. Want to replace the beat up modern baseboard radiators upstairs, and want to replace three non working antique baseboards with “expensive” working ones. If your price changes on a small job why would I trust it on bigger projects? Simple fact is I wouldn’t, I’m going to call another company. Maybe I’m wrong on this but that’s my logic. Thanks for getting the Ecobees in for my anyway, cheers!

Dyllan M.
Upon arrival I found there was no smell of oil in the house. Turned the unit on and found nothing wrong. The burner was reading 220 ohms which is very good. Combustion test was 0ppm. Walked through the house with my tester and found no traces of carbon monoxide with the unit running. I did find that there was a flex run that broke off of the ductwork. That flex line will need to be replaced because it’s too short now to reach the ductwork. I taped off the tap on the ductwork that was blowing hot air into the basement. the smell may have been coming fro there because it was blowing hot air right onto the insulation. The flue pipe is very thin and needs to be replaced. There were no holes in the flue pipe for my combustion analyzer which means the unit may not have been tested prior. I covered the new holes I made with silver tape which were giving off a smell because the tape was heating up. The smell will go away. Was not able to smell any concerning smells. The chimney has good draft

Found the zones labeled bed was very hot and the pump was not running. I loosened up the check valve and hit the side of it several times. Tightened the check valve back up and hit it a few more times. I also purged some water through that loop to get any loose debris out of the check valve. Turned on the boiler and watched it get up to temp. I now had 120*f before the check valve and 96*f directly after the check valve. A few feet down the line I had mid 60s. Before I did anything the whole zone was in the 120*f range. The check valve seems to be working and I was able to free it up. Recommend replacing the check valve. I included an estimate for the repair. 3/4” copper

Water was coming from the top of the extrol tank. Drain the pressure and replaced the extrol tank. Filled and purged the system. Turned the thermostats on and checked the operation.

Resealed around the flue pipe going into the chimney. Checked the extrol tank and found that water is starting to migrate into the air side of the tank. Recommend replacing the tank and hi vent. There was also corrosion on the circulator gaskets for one zone, which should be replaced. Included a quote for making repairs.

Performed heating p.m. on an oil boiler brushed and vacuumed. Replaced oil filter nozzle and strainer. Started checked safeties and performed a combustion test. There are several areas that have calcium buildup from leaks, the domestic coil plate is deteriorating from a leak and unknown if the steel is pitted. Recommend replacing the boiler due to the age of the boiler and the cost of the repairs.

Burner was off on reset when arrived. Reset the control, the burner did not fire. Checked oil flow fuel line was full of air. Bled the line until clean oil came out of the pump. Burner started, cycled several times and let the boiler come up to temperature. There was a couple drips due to the boiler was cold, waited until the boiler warmed up and everything sealed properly no more leaks at this time system is operating properly.
Larry H.
When arrived the zone panel for the circulators were making a chattering noise, removed the relay for The indirect, the relay at the end direct was chattering. Removed 24 V to the relay on the indirect and noise stopped. Checked the zone panel to make sure there was proper operation with the priority setting and the other zones. Turned the water on to see if the aquastat for the indirect would turn on but it does not. The aquastat needs to be replaced. Picked up part and replaced the aquastat for the indirect hot water heater. Started and let the tank heat up with hot water until it satisfied the aquastat and turned on the other zones. System is operating properly.

Upon arrival found the 0015 circulator pump inside the Weil McLain boiler had a loud noise to it when it turned on. Also found the circulator pump for zone 1 was making a winding noise as well. Customer wanted to replace both pumps. Drained down the system and replaced both circulator pumps. Filled and purged the system. Boiler got up to temp. Boiler is at 16psi. No water leaks. All zones came back hot.

Replaced the defrost board and the sensors it came with. Started and tested. After the delays the unit started up with no issues. I found the unit was low on refrigerant. Customer stated it hasn’t been serviced in roughly 10 years. May be a small leak starting to develop. Unsure at this time. Added 2lbs or r410a refrigerant. Unit required 11* up subcool. After I added the refrigerant I had 7-9* of subcool which is good. The inside temp was 59*f and after the unit ran for roughly 30min the temp was 66*f. I had 97*f supply temp air. Included the cost for the previous visit in today bills.
Larry H.
Upon arrival, the burner was off on reset. Reset the control and the burner started then went off on reset. Checked oil flow and transformer which were correct, checked the cad cell eye which had no reading causing the control to go off on reset. Replaced the guy and checked the readings. The cad cell eye was reading 1000 ohms. Replaced the nozzle which was dirty started and tested. The cad cell is now reading 513 ohms and operating properly.
Andrew H.
Upon arrival unit was running and had a large amount of air in the lines. Pressure was displaying at 40psi on the pressure gauge which is too high. Drained pressure and saw the pressure gauge was reading 15psi higher than the real pressure. Replaced the pressure gauge with a new one. Also added ball valves and new boiler drains on the return so the zones could be bled of air properly. Filled the boiler back up and bled all zones of air. Started and tested unit. Had hot water coming back from both returns and had no air in the lines. Unit is working properly.
Dyllan M.
Upon arrival I found the unit was off on reset. Found the nozzle assembly was covered on carbon build up. Replace the oil nozzle and cleaned the assembly. Attempted to clean access oil out of the fire chamber. Noticed there was no liner in the chamber and oil had seeped through the gaskets of the boiler. Purged the oil line and started and tested. The unit fired up with no issues. Combustion test was 4.4%o2 at 17ppm. Also found the boiler was at 29psi. I found the expansion tank is bad and the internal bladder has water seeping through it. Customer denied replacement of the expansion tank. System is up and running. All returns came back hot.
Dyllan M.
Upon arrival I found water on the floor around the front right corner of the boiler. When the boiler turns on and heats up I found water coming out of a hairline crack in the front section of the boiler. Customer would like a quote for a new section.
Dyllan M.
Replaced two customer supplied tstat. Eco bee thermostats. Had to run a new section of wire for the first floor. Had to wire up commons for the thermostats. Started and tested. Both zones work properly. They turn the system on and off as needed. Customer will be calling to set up a a quote for new baseboard.
