    I called them at 8 am and they had someone to my house by 9 am. They got my heat working again in no time.

    It took them a bit to get the parts we needed, so they came in to do what they could to keep my kids cool. It was reasonably priced and they didn't try to pressure us into spending more than necessary.

    The gentleman that came out to give me an estimate on a new HVAC system, was absolutely GREAT.My furnace had gone out, and he went above and beyond my expectations!!The furnace is what has shot craps, but was of course affecting the AC.He made sure I had AC before he left, NO CHARGE!!I will be using them for a new HVAC system as soon as I can afford it, and the price he quoted me was great.

    These people are just the best ever! The times they have been here except for one maintenance visit, we were in trouble - once when we came home from church on a Sunday in the frigid winter temps to find no heat in the house and another time this year when our AC went out in the heat of the day. Contacted them on the emergency line on the Sunday and he was there in less than an hour (we don't live in Mexico either) and had heat going again in no time! Recently when AC wasn't working called them around 4 pm and they offered to come right out, but since it wasn't scorching hot, we had them come the next morning. They have also done some repair on a gas log fireplace insert for us. They are responsive, professional, friendly and don't gouge you on their fees; we've always felt they were very fair on their pricing! Can't say enough good about this business!

    Called their emergency line close to 8pm on a July evening, because the fan on our AC unit quit working. Technician Chris was here within a hour, and had the issue fixed in about 30 minutes. Nice and informative, would recommend.
