Reconditioned Appliance’s

So why is a HVAC contractor selling and working on household appliances? Well the answer is simple, it’s where we started! As you know, we are family owned and operated and way back in 1958 my grandfather started a company called M & N Service Company. He repaired and sold reconditioned and new appliances. When John, his youngest son, was old enough to work (now remember, the 70’s were a different time) my grandfather had him learning how to work on refrigerators, washers, dryers and stoves. You see, appliances are not that different from heating and cooling equipment. Refrigerators have compressors; refrigerant and motors just like air conditioners and stoves have burners, ignitors and controls just like furnaces so they kind of go hand in hand.

When John was old enough, he decided to go out on his own and in 1989 Day & Night was born. In 1990 we incorporated. Starting from a garage, John and his wife began to build their business, expanding to a location in Lakewood, then a different spot in Lakewood. Another location change was needed as the company grew, we needed a bigger showroom. Finally, in 1998 we found our home and purchased a space in Southwest Denver. Recently, M & N Service Company was merged with Day & Night and we feel honored to be a part of the long history. We have a great showroom and large workshop for our appliances. Keeping to our roots of saving people money and offering quality rebuilt appliances. Stop by and visit our reconditioned appliance showroom.
