Randy, This is in response to your request for a comparison of our old fuel oil furnace and our new heat pump system you installed for us in October 2005. Over the past 10 years we used on average 500 gallons of fuel oil per year to heat our home. After the installation of the new heat pump we have averaged $40.00 per month. We are supplied electricity through Black Hills Electric Co-Op and pay 3.5 cents per KWH for the heating electricity. It would be an understatement, to say we are pleased with the heating cost reduction. - Paul Michael from Rapid City
Randy, It has been about three months now, since you and your team replaced my fuel oil furnace with a Trane electric heat pump. Tam and I want you to know how pleased we are that we made the decision to make this change in our heating and cooling system. Without a question, this was the best financial move we have made in a long time. Since you have installed our heat pump, our electric bills for heat have averaged about $30.00/month or about 10% of what I would have paid for oil heat. I expect to recover my $6,500.00 investment (the approximate cost of my system) in four or five years. This places no value on our peace of mind and increased security that we feel every time our furnace turns on. Having elaborated on how happy we are with our new system, I also want to emphasize how pleased we were with the service we received from Viking Mechanical and Black Hills Cooperative (BHEC). - Bill & Tam Colson from Rapid City
Randy, I just want to express to you how happy my wife and I are with our decision to install a heat pump in our home this past summer. As you know, I agonize over the decision for a very long time because of conflicting opinions from other HVAC companies. Despite my hesitation, we decided on the heat pump. On July 20, you and Josh installed a new water heater and heat pump in one day. I had heard all the stories of how a heat pump would really leave us freezing in the winter time and how the new, high efficiency fossil fuel furnace was the best choice in the cold winter months in South Dakota. Well, because of Viking Mechanical, we don't worry about carbon monoxide in our home, we don't worry about dirt from burning fuel, and we don't contribute to more air pollution by burning gas or fuel oil for heat. My wife immediately noticed the even temperature both in the summer and winter, it never varies more than 1 degree. Heating our house (2200 Square feet) thus far this season through February 28 has cost $145.00 That is less than 1/4 of the cost of last year with using fossil fuel. With you, service means exactly that.. a rarity these days. - George & Mary Corinne Bauder from Rapid City
Randy,Thank you for all your help with the design and installation of our heating system in our new home. The heat pump system works beyond our expectations. Our house is toasty and the electric bills are very reasonable. Randy Smart and his team along with the staff at the Black Hills Electric Co-Op, especially Mike Chase, have been wonderful to work with. They have answered all our questions, they have provided prompt and courteous service whenever needed. Whether it be heat systems or hot water heaters, those are the people to talk to. - Jim & Pam Ramp from Rapid City
Randy, I have just completed a heating - cost analysis for our home for the first three months since Viking Mechanical installed our new Trane heat pump last December. My Wife & I are both exceptionally pleased with its quietness of operation & stable heat, but most important was the greater than anticipated savings from heating with propane. As close as we can figure, our monthly heat cost went from $155.00 down to $42.00. WOW!! Thanks much for the nice neat installation and also appreciate the professionalism exhibit by your crew. It was exemplary. -  Larry & Sandy Warinner from Rapid City
They fitted us into their schedule and came two days earlier than their original estimate. They investigated, reported to us, we gave the go ahead to repair. It was fixed and we have had no trouble with it. This is the 3rd time they have been out and have always been quick and efficient. - Roxann Silbaugh, Rapid City
Things couldn't have gone smoother. Randy was very thorough in examining what needed to be done to complete the work. He informed me of his expectations and discussed possible concerns. Once I accepted his quote, he immediately ordered the materials and had his installer call to set up an installation date. Unfortunately, for the installers, they had to put the unit in on the hottest day of the summer. They started on time as promised. They were professional and neat and tidy in their work. They left the work areas, inside and outside, clean and as they had found them. Everything works great and my home is very comfortable now. Viking Mechanical was very easy to work with. - Betty Harris, Rapid City
Heating service on a 100+ year old house that we rent out was not working. The first time it was a heat sensitive switch the second time it was a blown out pilot light.  When the heat was out in our rental I had Viking Mechanical referred to me by a co-worker and friend. Called and although they were booked up they added the house on at the end of the day. This was right at the first cold snap of the winter and temperatures that weekend were slated to drop to the teens with high winds. So on a Friday they went and did the repairs and did not even charge extra for after hours or for an emergency.That Sunday the heat went out again. Based on the high winds Viking Mechanical recommended I check the pilot light before they made a call. The pilot light was out but I could not get it to stay lit. I called him back and he stopped by after his last call, started thepilot light and then called me to let me know that it had to be held down for a minute or more to heat up the fail safe switch before it would remain on. He did not even charge me for this call.I came away feeling like I had gotten old fashioned personal and thoughtful service at a good price the first time and a fantastic price, free, the second. At this point I can't see calling anyone but Viking for my heating and cooling needs. - Lori Pendleton, Rapid City
Ask Randy to come by my house and look at the ducting under my house because I wasn't getting enough heat in the back bedroom. He told me to email him when it was a Good time to stop by. I send a email on a Friday saying that Monday would Be a good day. He called me later that day and said he would be by at 9:30 on Monday . He arrived on time and spend a good 1/2 hour under my House looking things over. He told me that having the flex ducting replaced would make The difference of night and day and help my furnace run better . Two days Later he called with a estaminet and told me if I wanted it done to let him Know. I told him that I did want it done and he said he would get me on the books. The following Thursday he called and said he could get it done the following Monday. It was done in a timely manner and 6 dollars under budget!!! And it did make the difference of night and day . - Patti Barrett, Rapid City
They put a new furnace in for us in the past. They serviced another furnace for us as well. The service has been excellent. They are very reputable company. They are prompt with the service. - Karl Wittnebel, Rapid City
They came to service our air conditioner. They have serviced our furnace as well. He put in a hot water heater in the past. I have used them more than once and I have nothing but good things to say about them. They installed the water heater on a Saturday. They were very reliable and I can always count on them when I need them. - Paul Trontvet, Rapid City
They installed a heat pump and a furnace. The service turned out very well. They gave an estimate and it came up to be a little bit more. They were fast, came on time, cleaned up after themselves. I have had no problems with the system. - George Rankin, Rapid City
They installed all the furnaces and air conditioning units in our new home. They come back a couple of times a year for routine maintenance and change filters. I call and they show up. They are on top of it and provide great customer service! - Jeremy Walla, Rapid City
Randy, Our new furnace looks and works great! Hopefully our 2nd story furnace will serve us for some time. If it doesn't for some reason, it's nice to know of a quality company such as yours. Thank you for your kind, prompt and considerate service. I am already bragging of Viking Mechanical and their service to my friends. - Wayne & Susie Braun from Rapid City
