HVAC Services in Leonardo, NJ
Third-Generation HVAC. Honest Work Since 1977.
Swanton Energy Services has been a fixture in Leonardo since 1977, when James Swanton launched the business with one oil truck and one service vehicle. Today, his grandson Jeff Swanton, a third-generation HVAC mechanic who grew up in the trade, leads the company. For more than 40 years, we've served residential and commercial customers across with heating, air conditioning, indoor air quality, and energy efficiency services. If you're looking for an HVAC partner you can trust, contact us today.

Heating System Solutions
Monmouth County winters bring genuine cold, and a heating system failure isn't an inconvenience. It's a problem that needs solving fast. We install, repair, and maintain gas and oil furnaces, boilers, and heat pumps, servicing all major makes and models. Jeff's expertise in Heat Pump Service and Installation means that work is handled by someone credentialed for it, not just trained on HVAC generally.
Furnaces
Our furnace services cover installation, repair, and maintenance of gas and oil systems. Whether your furnace is failing to ignite, short-cycling, or not pushing enough heat, we diagnose the problem and fix it on all makes and models.
Boilers
Boiler problems range from pilot light failures and banging or gurgling noises to complete loss of heat. Our boiler services cover the full spectrum, from pressure and valve issues to restoring heat when it matters most, across all major makes and models.
Heat Pumps
Heat pumps provide both heating and cooling from a single system, making them an efficient choice for many Leonardo homeowners. If yours isn't maintaining temperature, fails to start, or runs continuously without reaching the set point, our well-trained technicians can identify and address the issue.
Water Heaters
Whether you're dealing with water that won't heat, an unpleasant odor, persistent limescale, or a visible leak, we inspect thermostats, pilot lights, heating elements, water pressure, valves, and sediment accumulation to restore your water heater to reliable performance.
Air Conditioning Services
Along the Raritan Bayshore, coastal humidity adds to summer cooling demands and accelerates equipment wear, making proper installation and consistent maintenance especially important. We service all makes and models, from initial installation through ongoing tune-ups.
Ductless Air Conditioning
A ductless mini-split system is a practical solution for spaces where traditional ducted systems aren't feasible, such as additions, detached garages, or rooms that never get adequate airflow. These systems also provide supplemental heating, making them a year-round option. We handle installation, repair, and maintenance so your system can perform reliably through the Bayshore's humid summers.
High-Velocity Air Conditioning
High-velocity systems are designed for older homes without existing ductwork. Small-diameter flexible tubing delivers effective cooling with minimal structural disruption, with no tearing up walls to run standard ducts. We install and maintain these systems and can evaluate whether high-velocity AC is the right fit for your home.
Indoor Air Quality Services
For homeowners along the Raritan Bayshore, elevated coastal humidity makes dehumidification and proper ventilation practical necessities, not optional upgrades. We install, maintain, and repair the full range of indoor air quality systems for both residential and commercial properties.
Air Duct Cleaning
Regular air duct cleaning removes dust, allergens, and contaminants that accumulate in ductwork over time. Clean ducts can also allow your HVAC system to move air more efficiently, reducing strain on equipment.
Air Purification
Our air purification solutions target airborne pollutants and allergens at the source. We install and service whole-home air purifiers for residential and commercial properties, with ongoing maintenance to help support performance.
Air Filtration
Effective air filtration captures particulates before they circulate through your living space. Regular check-ups and filter replacements help keep your system performing at the level your household needs.
Humidifiers, Dehumidifiers, & Ventilation
Balanced humidity matters year-round. Dry winter air calls for a humidifier; humid Bayshore summers call for dehumidification. We evaluate your existing systems or install new humidifiers, dehumidifiers, and ventilation systems to help keep your home comfortable across every season.
Energy Services
Our energy services are grounded in credentials that go beyond standard HVAC licensing. Swanton Energy Services is a BPI-accredited company, and Jeff personally holds BPI certifications as a heating and cooling professional, a formal recognition of competency in building energy performance. That training shapes how we approach every energy evaluation and upgrade we recommend.
Backup Generators
Keep your home or business powered during outages with our backup generator services. We provide installation and maintenance for a variety of generator models.
Energy Efficiency Solutions
From upgrading insulation to installing high-efficiency equipment, we offer a range of solutions to reduce your energy consumption and lower your bills. Our BPI accreditation means the improvements we recommend are grounded in building science, not a sales pitch.
Smart Home Solutions
Smart thermostats and programmable controls can meaningfully reduce heating and cooling energy use by adjusting your system based on occupancy and time of day. Our team guides you through the options and handles the setup. Learn more about our smart home solutions.
