Excellent customer service!!
I recently contacted Horst to help get my Lennox cooling system fixed as it had stopped working. Horst advised that he was aboslutely flatout dealing with all the work as a result of the recent hot weather and wouldn't be able to see me until next year! He then took the time to discuss the specifics about my unit and suggested a few things for me to try.

I went and had a go and after few repeated goes the air conditioner came to life!

Thanks Horst really appreciate your help.
