Home Bio-Heat B20 Fuels

Bioheat® is safe and provides a cleaner, more complete and energy efficient burn. It is a renewable energy source that reduces toxic emissions; it is biodegradable, and suitable for sensitive environments. It may actually extend equipment life and reduces periodic maintenance intervals. Bioheat® reduces Americas dependence on foreign oil and is creating jobs here at home.  The performance and properties are the same as your current fuel, and maintenance is standard. Most heating system manufacturers — like Beckett, Suntec Industries, and Carlin Combustion — accept Bioheat® and stand by their warranties with its use.

Air Conditioning Services

Weve been providing quality air conditioning systems for over twenty years. Let us help you choose the right system for your needs. Designing a new system is more than just making the system so it cools and works. Helping you “size” your air conditioning needs takes a company that understands your individual factors and needs such as your physical space that you can spare, the esthetics, and your lifestyle. Older air conditioning systems lose their efficiency over time, and it can often make sense to consider one of our high-efficiency air conditioning systems that can return your investment in energy savings in a relatively short time.  We offer a wide variety of air conditioning and cooling choices to meet the needs of your lifestyle, home or business these options include High-Efficiency Central Air systems with Higher SEER units that feature lower energy use or a High Velocity systems that take up much less space for ducts.

We are proud to use and distribute Newport Biodiesel

• Manufactured from local recycled restaurant cooking oil, by Newport Biodiesel. Newport Biodiesel uses underutilized restaurant oil that we already have here in the Ocean State.  Using local, recycled oil means less dependence on unstable foreign energy sources. And less need to convert our food crops to fuel crops or our forests to farmland.
• Approved by the US Department of Transportation. ASTM CERTIFIED.  Malloy biodiesel blends can be used in any diesel engine without any modifications, and with its greater lubricating qualities it can improve engine performance.  Biodiesel can be used in homes, buses, pick-up trucks, heavy trucks, machinery, passenger cars and marine use.
• As a local product, RI-made Biodiesel creates more jobs for Rhode Islanders and supports local family-owned businesses.  It is also a cost-effective fuel. And, as a cleaner burning fuel, it cuts down carbon emissions and other pollutants.  We pledge not to use food crops for fuel crops.
