Smoke alarm issue

Pleased with how quickly you came....and my dog is very happy he isn't hearing that noise any more! Service was professional and thorough. Mike checked the other detectors as well and took out the locking pin so that I can change the batteries myself if need be.

Sorry for the confusion on this. Please give a call with any questions! Furnace clean and tune. Cycled system. Checked heat exchanger, ok. Checked, removed, and cleaned burners and flame sensor. Both ok. Checked and tested igniter, tested normal. Checked and adjusted gas pressures to maximize efficiency. Checked and tightened electrical connections and clamps. Cleared drain lines. Preformed combustion test and found normal levels in exhaust. No CO found in airstream. System was very dirty and it is recommended for yearly maintenance on this equipment.

System problem. Customer stated that the furnace was short cycling. System would turn on for a min then cycle off. It repeats this over and over. This has been happening for the last few weeks. I checked filter. Filter was a bit dirty, but ok. Cleared drain line and checked drain trap. Cleared pressure switch tubing. No obstructions found. Cycled system and unit failed after a min with a pressure switch code. Removed intake venting pipe and cycled again. System ran for over 15 mins. Recommend furnace clean and tune. Recommend leaving venting off until cleaning. System operating at this time. Job complete.

Cycled the furnace. Checked the gas valve and performed a furnace combustion test. The furnace is running normally at this time.

Looked at fans that were loose. Found both fans had loose screws. Put washers on the screw heads so they wouldn’t pull through the bracket slots and tightened the screws for both fans.
