Washington Plumbing and Heating

We purchased a house in July 2014 with a gas furnace that had been inspected by Washington Plumbing and Heating, Inc. on June 17, 2014. On Monday, October 27^th, morning at 4:36 am, we woke up to our ADT alarm going off. I ran to the living room, thinking there was an attempted break-​in. Instead, the phone rang and it was ADT asking if we were all ok, because our carbon monoxide detector had gone off. My husband opened all the windows and doors and by the time the Fire Department arrived, they were unable to detect any CO. They advised us to call PSE, so later that day, a technician from PSE arrived to test our furnace. It had dangerous levels of CO present– 2000 ppm. He told me that they shut the gas off when there’s 100 ppm present. We had two companies come out to look at the furnace to see if our American Home Shield Warranty would replace the furnace. Both times, the request was denied because the damage to our furnace was deemed a pre-​existing condition.
This furnace was «inspected and maintained» by this company on June 17, 2014, yet after only a few weeks of operation this fall, it was producing potentially lethal levels of carbon monoxide. Three different people have now looked at the furnace and stated that the burners were corroded. The extent of the damage could not have happened in the three or so weeks we have used the furnace since we have lived here and certainly did not occur after June 17, 2014.
I emailed the company and received two emails back. On November 4^th, I was told «we will reply back to you on or before the end of next week.» On November 17^th, I was told «we will have your response tomorrow.»
I filed a complaint with the Better Business Bureau and the company never responded to them. The Better Business Bureau subsequently closed the complaint as «unanswered» on December 2, 2014 and the company’s rating dropped from an A to a D-​. My complaint is now available on the BBB’s website for the general public to see.
We contacted a lawyer who sent a demand letter to Washington Plumbing and Heating, Inc. on December 11^th. We asked for a response within seven days. The company never responded.
I could not in good conscience recommend this company to anyone needing to have a furnace inspected or maintained.
