Its always a pleasure having Denny over.  He's very friendly and courteous.

I own several rental properties in St Louis.  Denny Cover and Covert Heating and Cooling have been handling my HVAC needs since 2008.  He's done everything from installing a new furnace and air conditioner to simple repairs.  He's always on time and is very professional.  He also teaches HVAC classes at a local school, so he's very knowledgeable and can easily eplain to me what is going on.  Ive worked with a lot of different contractors over the past 5 years, and Denny is by far the most reliable
