We are the #1 Geothermal Heating and Cooling Experts in South Jersey, Central Jersey, and Southeastern Pennsylvania.  The U.S. EPA calls geothermal "the most energy efficient, environmentally clean and cost-effective space conditioning system available".  Upgrade to geothermal, and never buy heating oil or natural gas again. Don't just take our word for it when it comes to D&L's geothermal expertise. Here's what one of our recent customers had to say: “D&L has been an absolute life saver. We had the hardest time finding a tech who knew anything about geothermal systems, until we called D&L... A real standup, old school, quality service company. D&L got a new long-term customer in me, and I strongly recommend them.”

"He has done a good job."

Founded in 1984, Advanced Heating & Air Conditioning (AHAC) initially operated as Alpha Oil Company until 2000 when it transitioned exclusively to HVAC services. Established by brothers Lou and Danny Roerig, the business flourished under Danny's leadership until his retirement in 2009. The company, now helmed by nephews Louis & Nicholas, continued its upward trajectory by acquiring local HVAC businesses from 2010 to 2012, such as Advance Service Inc. & Ship Mechanical. Serving Warren, Hunterdon, and Middlesex Counties in New Jersey, as well as Lehigh and Northampton Counties in Pennsylvania, AHAC has built a strong reputation for exceptional customer service since its inception. Today, it remains committed to growth and customer satisfaction, adapting to meet the evolving needs of its expanding clientele.

"The tech called ahead to say we will be there in 35 minutes. They came on time! ( Between 10-12) efficient, knowledgeable and did a great job. Canâ t ask for better than that! Thank you!"

We're dedicated to providing our clients with the very best in service, installation, and repair for your heating and cooling needs. We are a locally owned and operated company that values honesty and integrity. We specialize in central A/C and cooling systems, as well as heating and furnace systems. We take pride in the quality of our work, and our commitment to outstanding results. We look forward to building long-term relationships with our clients, and guarantee your satisfaction! Visit us @ RJKMECH.com

"Short version: Professionalism, competency, and integrity is what you can expect from RJK. When our AC stopped working, another company came out to investigate and we were quoted an outrageous temporary repair cost and were advised to replace the whole system. We called RJK and they called back almost immediately. Upon arriving, they advised that a whole system replacement would be unnecessary for starters. But before even doing that, they wanted to have their techs double check that the system was truly in need of any replacement. Turns out the fix was straightforward and within 30 minutes the system was repaired at a fraction of the cost of the original contractor's quoted repair cost and definitely cheaper than a whole new system."

"Tech came out on Tuesday to service our furnace and look at duct work. Furnace was working but we could tell there was an issue. The tech told us that the diagnostics told him the furnace was ok but might need work in the future. 36 hours late our furnace stopped working. We called back and had the tech respond back out. They wanted to charge us another $135 service fee. Tech then found an issue with the capacitor and stated it needed to be replaced. Charged us $300 for a $35 part. The tech advised that the blower motor would most likely need to be replaced as well and quoted that at $2,290. 8 hours later our furnace stopped working again. The next day we hired a different company. They came out and advised it would cost $1,000 to replace the same. Before picking up the parts, the company checked and advised everything was covered under the warranty still and replaced the same for $350 in labor costs and service fees. The original tech made no mention of a warranty."

Heating and air conditioning services FAQs

Knowing how long your existing HVAC units can last is essential to determine if you need a repair or replacement. Typically, most modern air conditioning units can last between 15 to 20 years, and most furnaces can work properly for 15 to 30 years. If your HVAC system is on the older side and you decide to replace one unit, it might make sense to replace both simultaneously to save on costs and future hassle.

While different HVAC contractors might offer higher or lower prices than competitors, the best time to replace your HVAC system is when customer demand is low. The beginning of summer and the beginning of winter bring the most demand for HVAC systems, so if you can, consider replacing your HVAC units in the early spring or fall. Many HVAC companies offer special off-season coupons that help lower the overall cost.  

The average cost to hire an HVAC contractor is between $50 and $150 per hour if charging hourly. However, some HVAC contractors will charge a flat fee by the type of service they are performing—for example, an inspection can cost between $150 to $500. Keep in mind that emergency repairs—which are made after business hours or around major holidays—generally cost more than scheduled repairs.

Yes, most states require HVAC technicians to be certified, and for good reason. Hiring an unlicensed HVAC technician could lead to poor quality work, costly future expenses, and potential code violations. 

As you browse our pro listings, take note of the “Angi Approved” badge. Angi Approved businesses meet our standards for certification which include: 

  • The owner, principal, or relevant manager passed a criminal background check

  • Required to have applicable state and local licenses

  • Maintain an average star rating of 3.0 or better on our network, if they have at least one review

  • Paying to advertise their services

  • Meeting any other eligibility criteria required by Angi

Keep in mind licensing is different from certifications. A license is a legal requirement to operate a business, while certifications are voluntary.

The average cost of HVAC repairs is around $350. However, that price can be as low as $100 or as high as $2,000 or more, depending on the repair. For example, replacing a capacitor is a relatively inexpensive repair, ranging from $100 to $500. However, a compressor repair is a more expensive repair, ranging from $750 to $2,000.
