"So far this year we have had both furnaces replaced, one humidifier, and a couple of service calls. Whether it was the service calls, sales calls, or installation calls, we have been entirely satisfied with the services of Althoff. The employees and management you have provided us are second to none. While we hope to see a little less of you going forward, it was a pleasure as always doing business with you. Sincere thanks."
