Job Locations and Reviews
I started off with checking all electrical connections inside and everything looked good. The client replaces his own filters. I cleaned the trap and condensate pump with cleaner. Next I went outside and washed the outdoor unit with water and then soap. I checked the electrical connections outside and everything looked perfect. Lastly I checked the operating pressures in heating mode since it wasn’t warm enough to do it in air conditioning mode. The pressures looked good.
Replace pressure sensor on York modulating natural gas furnace.
Dropped off shower head.Moen brushed nickel
Excellent service
Comfort height, white, elongated bowl.
Mark and his family run a top tier heating and plumbing business. I would not go anywhere else. I have three houses and they take care of everything.
When I arrived I turned the furnace on and it tried to start but it produced an error code of a pressure switch being closed prematurely. After trouble shooting I closed in on the issue being caused by the infamous York pressure sensor. I removed it and blew it out and cleaned up the electrical connections on it as well. I turned the furnace back on and it fired. I cycled the furnace at least 5 times and let it run in order to ensure the problem is fixed.
