Due to the lack of resources in the available labor situation, we are having to remove our 24-hour service availability to customers. Once we are able to restate 24-hour service we will change our hours of service back to 24-hour emergency service. We apologize for the inconvenience at this time, but look forward to continually servicing all of our clients with 24-hour service in the near future. Sincerely, Michele Thomas

Courteous, thorough, on-time service
- Oak Ridge, TN 37830
I was pleased that Juan left a voicemail message announcing his pending arrival, arrived in the time range promised, completed his service checklist, then cleaned the coils and removed pad level debris from the outside unit. When I if Juan could add anti-rust tablets to the condenser pan, he said he could add them for a specific price, then did so. However, before leaving, he informed me that my out of pocket cost was actually less due to this being a prepaid service call.
