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.

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!

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 some corrosion starting to form on the outside of the boiler between sections. Brought the customer down to show them the condition of the unit. Would recommend starting to think about replacement. The unit is from 2000

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
