Services
Alternative Heat Source is a local, family owned and operated business, started in 2006 by husband and wife team Carl and Kathy Sweezey. What started as a small showroom right off of 302 in Naples has grown to a larger showroom with a pellet and parts warehouse. Alternative Heat Source offers a well-trained, certified team of technicians who continuously attend industry workshops to expand their knowledge.
Pellet grills are gaining in popularity. Green Mountain Pellet Grills are affordable and give food a great flavor. We also sell Old Hick Applewood and Hickory grill pellets designed specifically for pellet grills. Green Mountain's best-selling model sets the industry standard for pellet grills. Available options include a stainless steel no-warp lid, form-fitted grill cover, dome thermometer, and Wi-Fi controls.
We offer a variety of hardwood, softwood, and blended pellets from New England and Canada. Pellets can be delivered for a fee (5 ton maximum per trip), or can be picked up from our shop at no extra charge. Please note that pellets from Canada are delivered as a metric ton with 10 extra bags and are priced accordingly.

Alternative Heat Source is an amazing, family-run business ready to help you with all of your fireplace questions!
I recently moved into a house with a beautiful open fireplace. While a delight to watch, it was very inefficient for heating — I felt like I was throwing a log in every few minutes that did little to warm the room. I went to Alternative Heat Source to see what sort of options were available. Carl helped me identify a great option: putting an efficient wood stove partially inside the existing fireplace.
Kory came out and walked me through all of the details of what modifications

I could not be more pleased with my new propane Regency fireplace. Carl, Kory, and Cathy are so easy to work with and very responsive. Kory and team are very knowledgeable and do meticulous work. I highly recommend Alternative Heat Source for all you stove and fireplace needs.

It was a pleasure dealing with Carl, Kory and Kathy. They were very personable and professional from start to finish. Bottom line is that they sold us a great gas fire place, gave us a fair price, did a clean and professional installation and did everything on time as scheduled!
The service provided to us by Alternative Heat Source Inc. was exemplary!
I would highly recommend this company without hesitation.
Thank you for such great professional service...you don't see this kind of "old school" attention to detail anymore!

Overall very pleased. Alternative Heat Source provides you with support for the entire process including selecting your stove, stone/ mason, mantle and granite. We have installed gas fireplaces with other providers over the years and this is our first experience with Alternative Heat Solutions and we highly recommend them.

What a terrific experience!! Alternative Heat Source replaced my inefficient, outdated propane fireplace with a QuadraFire pellet stove insert and I could not be happier!! Kory communicated incredibly well, starting with the quote process, through the ordering and then the day of installation. He did an awesome job of minimizing the mess of the install (perhaps he is magical because I have no idea how my living room remained so clean!) and, before he left, took me through operation and maintenance tips. I would definitely recommend Alternative Heat Source!!

What a wonderful experience from the moment we walked into Alternative Heat source! We were not sure what we wanted but Carl and Kathy helped us decide on the perfect stove and size for our space! Then we decided on a piece of granite to place underneath it. While picking the granite out Kory was helping us through texts, they were guiding us through the entire process. Then the install went smoothly just a few weeks later. They were very neat and cleaned up after themselves.
I would highly recommend Alternate heat source for all stove needs!

Kory and all of the alternative heat team did such an amazing and efficient job on installing our first Woodstove. They squeezed us into a busy and full schedule and got it done! They’re very knowledgeable and took time to answer questions we had while they worked. From the planning stage, to the install date, we had experts all along the way. THANK YOU!!

Kory at Alternative Heat Source did a phenomenal job helping us pick out the appropriate propane fireplace insert, choosing the best location for the propane tank as well as running the propane line inside our home, and the actual installation. I cannot rave enough about Kory's professionalism, promptness AND always keeping us in the loop during all phases of the project. I highly recommend Kory and Alternative Heat Solutions.

I can't say enough good things about this company. I was dealing with frost and flame that put me off since September who could not fix my pellet stove after 3 visits so that being said I was without heat since September I finally called this company on Saturday and they were at my house and fixed my stove on Tuesday the repair man was very knowledgeable and respectful who did his job very well I am one happy customer to have found this company. 5 stars for sure!!!

I bought a Quadra-fire Trekker pellet stove from Alternative Heat Source in October 0f 2019. The staff is very knowledgeable and professional and the stove is excellent quality and runs like a watch. It easily and efficiently heats our large home. I highly recommend this local company.

From the moment our family walked through the door of Alternative Heat Source, Karl made us feel comfortable.

He did not try to "sell" us a stove, he educated us on the differences, and made a recommendation based upon the stove we were currently using. His son, Kory, came out two days later and took a look at our current stove and chimney layout. He spent nearly an hour looking things over and patiently putting together a couple different quotes for us to ponder. Over the next few days, I emailed Kory with many questions, to which he was receptive and honest, and never tried to pressure

Kory was great to deal with! We had an appointment with Irving to install the gas lines and tank and Kory rearranged his schedule to be at our home early and have the stove installed before Irving came out that day.

After the stove was installed he assisted the Irving tech with the install, and stuck around until the propane was fully functioning. He tested out our stove and showed us how to work the remote and all the features of the stove.

I highly recommend their work and professionalism!
