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.

Heating and Air Conditioning questions, answered by experts

Yes, having mismatched evaporator and condenser coils in your AC system can lead to serious issues. For instance, it can result in higher monthly energy costs as the system runs longer to compensate for the mismatch. This mismatch can also put extra stress on the system, compromising its efficiency and longevity. 

Along with that, mismatched coils can lead to higher temperatures and humidity levels in the home. What’s more, using coils of different sizes may violate the manufacturer's warranty, as they are designed to work synergistically, and any mismatch could lead to repairs and system failure.

As mentioned above, not all HVAC Schrader valves are necessarily the same. While the valve core and pin or spring size on Schrader valves used for HVAC are generally similar, the valves are not all universal and interchangeable. The size of Schrader valves varies depending on whether it's used in an air conditioner, bicycle tire, or motor vehicle tire.

Good news: Your AC system doesn’t need Freon (a popular refrigerant) added regularly, if ever. Freon only needs to be added when there’s a refrigerant leak; however, it’s not uncommon for a gradual leak to occur every 5 to 15 years. Signs of a refrigerant leak include higher utility bills, increased humidity in the house, weakened AC performance, and a hissing sound from the system.

High humidity is one of the most common reasons for air vents to sweat or produce condensation. When the cool, dry air from your HVAC unit meets warm and moist air in your home, it will cause condensation. Insulating your ductwork can help prevent this. If you live in a very humid region, a dehumidifier can also help.

Whether an HVAC damper should be open or closed depends on the season, the zone it controls, and the temperature in that zone. In the summer, open upstairs dampers and close lower-level dampers to get the most efficient cooling possible. In the winter, do the opposite. Cool air will naturally flow down to lower levels, while warm air will rise. This keeps your system from working harder and helps prevent common AC problems.
