To better serve customers in Allentown, Bath, Bethlehem, Easton and east central Pennsylvania, we offer top-quality products and customized services that are backed by decades of experience. We're available to provide these comprehensive services when you need them. Maintenance is the cornerstone of our business. Our team is qualified to service and repair air conditioners and heat pumps, plus boilers and furnaces that use gas or oil. We do everything from performing seasonal tune-ups to replacing faulty parts.

Sullivan Oil & Propane was founded on the principle that a company should provide quality products, outstanding customer relations and practical services to the local community. This philosophy has served us well and helped our company grow into the 21st century. When we started our business in 1992, we were a local fuel delivery company. Today, we are a full-service AC company with more than 20 years of experience in the field. In keeping with our original business model, we continue to provide quality heating oil and propane to thousands of businesses and homes in Lehigh County and the surrounding area.

If you need an air conditioner repair, Sullivan Oil & Propane is standing by to offer priority service to customers in east central Pennsylvania, including the Poconos, Lehigh Valley and the cities of Bethlehem, Allentown, Easton and Bath. Although eastern Pennsylvania isn't as hot as some places, our summers can be extremely humid. Using an air conditioner is the most effective way to cool large spaces while removing the oppressive humidity that makes everything feel hot and sticky. If your cooling system breaks down on the hottest day, it can make everything unbearable.

Upgrading or replacing your heating system is an important decision. There are quite a few things to consider. How much will your new heating system cost? How long will the installation take? What type of furnace or boiler should you purchase? How efficient does it have to be? On the bright side, our experts are available to answer all of your questions and guide you through the process even if you need to make a decision quickly. If your current heating system isn't functioning properly or will cost too much to repair, you have an opportunity to invest in a replacement that will lower your utility bills, reduce your impact on the environment and provide dependable service for years to come.

Investing in a new central air conditioning system is an important decision. If you've been thinking about upgrading your air conditioner or if you need a replacement immediately, our installation experts can help you take the next step. Our team members will work with you to select a high-quality air conditioning system that will deliver comfort and efficiency with a price tag that you can afford. At Sullivan Oil & Propane, we are a factory-authorized contractor representing Carrier, one of the most respected names in cooling.

Scheduling pre-season maintenance is the single best way to prolong the life of your residential or commercial heating system. When the cold weather sets in, the first thing you should do is schedule a pre-season tune-up. If you aren't sure what your system needs or when it should be tuned, ask us about preventive maintenance agreements that can be tailored to your individual needs. When your heating system is working fine, it's easy to overlook the importance of preventive maintenance. Although your heater might not lose efficiency in one season, your system will experience more wear and tear if it isn't serviced regularly.

Spring is tune-up season for your central air conditioner. It's easy to forget about preventative maintenance when your equipment is working perfectly. To stay ahead of the rush, schedule a seasonal tune-up for your air conditioner at the beginning of daylight saving time. Our service technicians are available to perform repairs and maintenance throughout the year, but it's often easier to schedule a convenient tune-up before the height of the cooling season. Invest in air conditioning maintenance now to keep your home cooler, prevent unwanted repairs and save money all summer.

Regularly scheduled maintenance for all of your heating and air conditioning systems provides a number of benefits including increasing the life expectancy of the system, improving efficiency and helping to save you money on energy costs. It may also prevent what is now a small problem from becoming a large problem. Our Maintenance Plans will take the guesswork out of your regular system maintenance, and you'll have a trusted partner in Sullivan Oil & Propane who will ensure the maintenance, repair and replacement of your HVAC system.

Offering high-quality products and services is what we do best at Sullivan Oil & Propane. We put an emphasis on training, experience and treating customers with courtesy and respect. This philosophy has earned us loyal customers who count on us for all of their heating and cooling needs, and you can count on us too. Whether you need an emergency repair, a seasonal tune-up or a system replacement, we're here to provide exceptional service and quality equipment from the industry's best brands. We stand behind our work and offer an unconditional guarantee on all replacement parts and labor.

The secret to getting more from your air conditioner is investing in maintenance before the cooling season begins. Whether you have a central air conditioner or a versatile all-weather heat pump, we'll make sure that it's in tip-top condition. Our experienced technicians are trained to perform a complete range of air conditioning services on equipment manufactured by all major brands. As a full-service HVAC company, we are pleased to provide these services to customers throughout the local area.

When the weather takes a turn, nothing is more important than a safe, reliable heating system. As a full-service heating and cooling company, we're available to perform heating repairs, pre-season maintenance and installation services. To ensure that your family stays warm in the worst conditions, we can handle all of your heating fuel needs with reliable delivery and auto scheduling. For a trouble-free heating season, start with a fall tune-up. Investing in preventive maintenance is the best way to get more from your heating system while spending less.

Heating problems can happen to anyone, and they usually happen at the most inconvenient times. Following years of reliable heating, you might wake up in a frigid home. The furnace might blow cold air or turn on and off without heating your home. After two decades in the heating and cooling business, we've seen everything. Our experienced technicians are trained to handle all common heating problems swiftly and effectively. Your comfort is important to us. Whether your equipment is nearing the end of its life or can be fixed quickly and easily, we will do whatever it takes to get your system up and running.

I have been with Gene Sullivan since the beginning. Gene's word is gold. He will go after a problem and won't stop until it is solved. Would not.

Had both our air conditioning & heating systems put in by this wonderful company. Very fair price. Also have had multiple seasonal tuneups and oil.

I've used Sullivan for about 14 years, and never had any issues. Recently I've converted from oil to propane. The techs did a great job.
