I Was referred to Collins Heating and Cooling by a friend of mine. I had a gas leak coming from my hot water heater so it was imperative that I get someone to fix it fast. I called them and explained the situation. Darren Collins arrived within 30 minutes! He was very polite and informative. I had called a couple other places that were referred to me as well, they told me it would be a couple of hours before they could come over and their prices were outrageous! I highly recommend Collins HVAC in Florissant and will be using them from here on out! Thank u so much Collins! read more
