I am currently building an Energy Star home in Hampton, NH. When it came time to choose my HVAC system, I decided to go with a geothermal system. As a retired airline pilot, I am a stickler for details and how a system works. After researching and contacting several HVAC companies, one company stood head and shoulders above the rest. Bill Wenzel Heating and Air Conditioning was, by far, the most knowledgeable and was also very price competitive. Mr. Wenzel has a real passion and enthusiasm for the systems he installs. Like Mr. Wenzel, his employees are truly very well-trained, knowledgeable professionals. After researching his company and meeting with Mr. Wenzel, who has over 35 years experience in the field, my choice was an easy one. Without reservation I would highly recommend Bill Wenzel Heating and Air Conditioning. Gary Alie Hampton,

My wife and I want to thank you for all your outstanding work and service over the years. There is no other outfit as knowledgeable and as efficient as yours. Whenever we’ve needed service you have come right away and you have always explained in detail what you’ve done. Billy and Karen Glazier Carlisle, Ma.

“Bill Wenzel HVAC Inc. provided a team of professional and friendly technicians who installed the geothermal system in our new house on time and on budget. Bill and his crew gave us a quality product that was installed in a quality manner along with rapid responses to questions and concerns. The few service calls we’ve made were answered and corrected immediately. There is no question that if we ever build again Bill Wenzel will be the HVAC choice.” Bob & Rose Gamache Bedford, NH

This is by far the best heating and air company we have had maintain & service our system. The techs are knowledgeable & efficient. Appointments are easily made and have always been on time. The cost for service is reasonable and fair. We are incredibly happy to have found BWHVAC and have complete confidence in the work they perform. They have a level of professional expertise that is almost impossible to find these days! Anders & Amy Vikstrom

Bill Wenzel and his employees retrofitted a geothermal system into our 1930’s colonial. They did a great job – here when they said they would be, work was always neat and left things neat. The heat is wonderful- things are much more even than our previous oil furnace. Bill told us we wouldn’t need a humidifier in the system, and he was right. The heat is much less dry. All in all a good experience and wonderful result. Lee Friess Portsmouth, NH Excellent quality and service Very professional Dick Messina Geothermal works. Our heating bills went from $5500 a year with oil to $1200 a year with geothermal. Richard Kalin Hollis, NH We are extremely happy with our geo thermal installation. Once we made the decision to go for it Bill made himself available and involved from start to finish in a very professional manner. We felt that the whole project was top priority for him and he took pride in his work. He always returned my phone calls promptly. This system has saved us money in fuel bills as well as maintenance of the oil boiler as the only filters that need changing are easy enough for the homeowner to maintain. I really cannot express how thrilled we are with our new system which happily includes central air. Paul & Dorothy LaFlamme

We use and recommend Bill Wenzel Heating & Air Conditioning, Inc. because of his years of experience, quality of workmanship and knowledge. We are confident the job will be done right the first time! Skillings & Sons, Inc. 603-459-2600 800-441-6281 Celebrating over 40 years of quality service! I am writing this letter to recommend Bill Wenzel for geothermal heating installation. Bill did not install my system but he corrected the problems with it. My system was installed by a local company and we had multiple problems with the system. The company that installed the system had been back and forth to our house at least 50 times. The company was unable to figure out why the system was not performing correctly. My neighbor had the same system, however his was installed by Bill. I contacted Bill and he came and solved the problem immediately. The system is performing really well. Our average heating and electric bill is approximately $250.00 per month to heat a 36 hundred square foot home with twelve foot ceilings. I will also add that when I had additional needs for bills service he was always there the same day and he was traveling from Nashua to Rye NH. Bill is very professional and definitely knows what he is doing. I strongly recommend his company and the geothermal system. Patrick J. Kane

Bill, Many thanks for all your help with my heat pump problems of last February. As you know, I had called the company that had installed the heat pump some years before, and after three attempts they had not been able to fix the problem. I had then gotten your name from the distributor for ClimateMaster and you came highly recommended. When I called you, you were not only very responsive and helpful over the phone, but clearly knowledgeable and experienced in water-based heat pump repair. Your serviceman was equally efficient and quickly diagnosed the problem, bought a part locally and installed it, all within a few hours. The heat pump has worked perfectly since, and your charges were very fair. I am very grateful to you for such prompt and expert service, and I would be happy to recommend you for heat pump repair issues to any homeowner or business requiring it. Please feel free to give my name and phone number to anyone requesting a reference. Gary Lamphere Exeter, NH

NH “I spoke to 6-8 HVAC companies when building my new home. When I asked each how many geothermal systems they had installed most proudly claimed 6, 10 or maybe 15 over the years. When I asked Bill he responded “somewhere north of 300!” Now that was the experience I was looking for. Bill critiqued my professionally designed system and suggested ways of reducing the cost while improving reliability. I followed all his suggestions and have a flawlessly performing heating/cooling system that is quite, comfortable and inexpensive to run. Plus, all my friends think heating your house with water is science fiction!” Peter Marconi Dover, MA Bill, I can’t thank you enough for your exceptional design and installation of our geothermal system. I could tell from our first meeting that you were the right guy for the job as you were by far the most knowledgeable and experienced of any of the other firms I interviewed for the job. We have been completely satisfied with the system and the service that you, Jane and your entire staff have provided since our installation in 2006 and would highly recommend you to anyone that is considering geothermal. Robert L. Wofchuck Ledgewood Wealth Advisors, LLC 92 Portsmouth Avenue, Suite 15 Exeter, NH 03833 P: 603-773-0080 F: 603-773-0090

What can I say about Bill. This guy had the personality and expertise like no one I have ever worked with before. I really enjoyed his humor and precision. Bill’s team was very thorough and took on my project like a … He designed and installed the geo thermal heat pump system like a work of art. Every move was precise and calculated. There was no guess work. He showed up when he said he would and completed the job on time, within budget. Every time I had a question, even to this day, he answers his phone or calls me back in a timely manner. It was a pleasure to work with Bill and I would highly recommend him. I am looking forward to working with Bill again on my next project. If you are looking for a company to design and install a Geothermal Heat pump system, please give Bill Wenzel a call and tell him I sent you. Dana Ritchie – see www.10drummertrail.com Laconia, NH

GEO Thermal is a simple concept but its implementation into a complete house system is not simple. Bill’s depth and grasp on all of the details of GEO and how it connects to the other trades has made the process painless. I would recommend working with Bill to anyone interested in installing a GEO system. Gary Orbeck My company, Wood & Clay Inc. “Fine Homes” has been building in the Lakes Region of NH for over 30 years. We recently worked with Bill Wenzel Heating & Air Conditioning, Inc on a design build geothermal system on a Winnipesaukee Lakefront home. Working with their team of knowledgeable professionals has been a great experience! They were able to advise from design to completion for a highly efficient & cost effective home heating/cooling solution. John B. Robinson President/Owner Wood & Clay, Inc.

Bill Wenzel Heating & Air Conditioning installed two geothermal heat pumps in our new Energy Star home built in 2006. We have less problems than we ever had with oil and there is a huge price savings. Heating, air conditioning, whole house ventilation, and domestic hot water generation from the geothermal desuperheater for our 4,800 square foot home utilizing the PSNH Heatsmart program at today’s rates is $0.44 per square foot or around $2,100 per year. Bill can send anyone my way for a recommendation. Bob Farr Wilton, NH

After interviewing and receiving quotes from 6 Geothermal suppliers/installers, I selected Bill and Company as they provided the most practical, least complicated, and most competitive system. Practical advice and delivering 100% on his commitment was only the beginning. Bill’s crew were all professional, on time, and on budget. I have a 2500 sq ft home with a lot of glass and in a very exposed, windy site. The system he designed works exactly as planned and keeps the house warm in any weather, for less than $100/month in heating/AC bills, yes in NH. Bill’s post installation service went above and beyond my expectations. I highly recommend Bill Wenzel! – Mike W, Newbury
