Found unit on a low pressure lockout. After resetting equipment tested in both heating and cooling and refrigerant pressures appear normal at this time. This is a rental property and landlord arrived about a week ago and since they turned the heat on, it has not satisfied temperature. I attempted to recreate issue but did not reoccur. System checked out good while on site. Issue could be intermittent soi advised landlord that if it persisted or worsened they would need to call us back out at time of failure. System is operating at departure.
