Heat maintenance. Checked blower motor, heat strips, compressor and fan all are in accordance to manufacturer specifications. Pressures are within range to outdoor ambient temps. Homeowner states there is an intermittent issue with the compressor going off and having to wait to come back on then runs fine. I advised we could set up a later date to come back with service manager she said she would speak to her husband and call back to set up time if they feel necessary. System is running correctly and efficiently at time of departure.
