Of course, the heat went out at 4pm on a Friday before a long weekend (doesn't it always?). I heard a loud bang come from downstairs. I had heard it before, but the heat usually came on right after, so I assumed it was the heat just bowing ducts in our crawl space. Well, this time, the heat didn't come back on, and I smelled gas in the house. The smell cleared once I opened a window, so I had an idea it wasn't a constant leak, but I erred on the side of caution and decided to call an HVAC company. I tcalled a couple other high-rated options here first (literally just went down the list), but neither could come out until tomorrow, at the earliest. Considering tonight is dropping into the 20's, I kept looking to get an appointment this evening in the hopes of having heat tonight. Enter Moncrief. The woman I spoke with was great, and listened to my entire story, and had me double check for the gas smell to be safe, which was nice. She said she could have a supervisor over to my house in about an hour. Then she ran down the cost with me ahead of his arrival, which was a nice touch as well. The cost was more than the other two companies I called, but I assumed that was due to the last-minute nature of the appointment, so I was fine with that. The breakdown was $59 for the tech call then $41 for each 15 minute block of work. The tech arrived within the hour. He took one look and knew exactly what the issue was. He did his work in a timely manner, then made sure everything was working properly before heading out. And so far, things are working smoothly. The 'bang' I was hearing was actually a few of the burners not igniting due to blocked exchanges, leaking out gas, and then that gas catching fire in the furnace via the pilot. The reason it didn't catch this time was the mini-explosion pulled in a draft that blew out the pilot and burners. Quite happy with the experience, though, price wise, for what the tech did, it's a bit expensive. I get the $59 up-front charge for the 'emergency' call, but $82 for a quick diagnostic and some minor dismantling/vacuuming is a bit steep in my opinion, though from the other prices I received, seems to be par for the course. They were professional, friendly, and very helpful though for this jam, so I'll definitely consider them at the top of my list for future work, so long as the price doesn't keep trending on the high side for future requests.
