HVAC Installation
We install high-efficiency heating, ventilation, and air conditioning systems tailored to residential and commercial spaces. Our technicians use trusted brands like Buderus and Viessmann to ensure durability and energy savings. Proper installation prevents future breakdowns while optimizing comfort and reducing utility costs for long-term value.
Propane Heating
Our propane heating services include tank maintenance, furnace installation, and fireplace inserts for reliable winter warmth. Propane systems offer cost-effective, efficient heating that operates during power outages. We ensure compliance with safety regulations and provide annual inspections to maintain warranty validity.
Oil System Maintenance
Regular maintenance for oil furnaces and tanks prevents leaks and improves efficiency. We clean components, inspect vents, and replace worn parts to extend system lifespan. Annual servicing helps homeowners avoid costly repairs while maintaining optimal heating performance and environmental safety.
Duct Design
Custom ductwork solutions enhance airflow and indoor air quality in new or renovated spaces. We calculate heat loss/gain to size systems correctly, reducing energy waste. Properly designed ducts minimize noise and ensure even temperature distribution throughout buildings.
WETT Inspections
Wood Energy Technology Transfer (WETT) inspections verify fireplace and stove safety compliance. Our certified inspectors check clearances, venting, and structural integrity to reduce fire risks. This service is essential for homeowners installing or maintaining wood-burning appliances.

My husband called for a furnace clean, and the guy came on Nov. 2, 2021. He cleaned the furnace, and after he was done, he then condemned the oil tank, and put a no fill on the oil tank. So then the furnace couldn't be used because we couldn't get any more oil. My husband was estimated that a new oil tank would cost over $3000.00. If we would of been informed of the oil tank being condemned, we would of replaced the furnace with a propane one instead of having it cleaned for nothing. We received a bill for his cleaning service. In my opinion, you would think if someone was a "professional" service

Showed up on time for initial appointment, promised a quote within a day or two...two weeks later no follow up and no response to my follow ups. Understand everyone is busy but best to just advise potential customers you don't want the work vs. stringing people along.

I would recommend Leonard Fuels. We got our new propane furnace from them. Their staff was very easy and good to deal with and the installers were very knowledgable, fast and professional.

Done business with them twice. Had my oil furnace installed many years ago and never had a problem with it. When my oil tank was due to be changed, i had them install a propane furnace. Great work and very friendly people there. Will hire again if i am in need again.

Good prices, and very nice, helpful people! Thank you! I hope to obtain a propane boiler system from you to replace the wood boiler that was installed previously in a home I recently purchased in Mississippi Station. Eagerly awaiting your quote. Thank you!!

Fantastic and friendly people. Got my propane tanks through them at a great price. And they helped fix an error with my furnace made by the installer. Glad I chose them to deal with for my heating fuel.
