Excellent

Andrew seems so knowledgeable in everything he has done for me and explains everything. He is also very kind and seems to take pleasure in making things easier for me.I am very comfortable placing my trust in your company to do the right thing by me. It’s been a very difficult couple of years since Gary died and as you know I have had to take on everything myself. I am getting educated in many things thanks to you. Keep doing what you are doing.

Good service, steep cost!

Good customer service, very nice technicians that show up when they're supposed to. If I had a negative about the experience it would be the cost for the service, a furnace and hot water tank cleaning shouldn't cost you an arm and a leg, it's not for individuals who wouldn't be able to take the sticker shock.

Performed pm on oil boiler 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 very high levels of sludge at the oil filter and also saw some water in the oil filter canister. Recommend getting a sludge and water additive for the oil tank. Also saw 2 hi-vent were showing signs of corrosion and were no longer working properly. After getting customer authorization we replaced both hi-vents. Drained pressure from the system. Removed both hi-vents. Filled system back up with water. Purged both zones of air. Started and tested the system. Had hot water coming back for both zones. When leaving boiler pressure was 20 psi.

Customer turned the thermostat on, the damper opened and circulators turned on but the burner did not light. Found the pilot flame was out. Lit the pilot and checked the thermocouple. The main burner started. Cycled several times. System is operating properly.

Customer turned the first floor thermostat on. Checked the boiler, did not hear the circulator turn on. Checked for power. Had 127 volts at the aquastat and at the circulator but it’s not turning on. The circulator is bad and needs to be replaced. Customer would like to replace the first floor thermostat also. While working on the circulator, noticed that the extrol tank was full. Recommended replacing while the system is draining. Drained the system and replaced the circulator and extrol tank. Filled the system and purged. Removed the thermostat and installed a Honeywell T4 thermostat. Started and tested.

Upon arrival unit was off. Customer stated the boiler was leaking a large amount of water from the pressure relief valve. Turned unit on and found when the boiler heats up the pressure rises up over 30 psi which causes the pressure relief valve to release water. The extra pressure when the water heats up is from the expansion tank going bad. The expansion tank holds extra pressure for when the water heats up and is supposed to keep the boiler pressure constant. After getting customer authorization we replaced the pressure relief and expansions tank. Drained water from the system. Removed old pressure relief and expansion tank. Filled system back up with water. Bled main loops of the boiler and went to each radiator and bled every one. Started boiler up and went to all radiators to ensure they were heating up properly. Unit is working properly. Boiler pressure when leaving was 21psi
