3 Essential Tips to Keep Your Furnace Hot All Winter

Why Is My AC Turning On and Off?

South Jersey homeowners know the importance of a reliable air conditioner in the summer. So when your AC turns on and off, it can cause concern. But you can trust the expertise of Reliable Heating & Cooling to diagnose and fix these issues, restoring your comfort and peace of mind. Read on to learn about some common reasons for this issue and how we can help!


Short Cycling

What is short cycling? It is the term used for an air conditioner turning on and off quickly before a cooling cycle is completed. A typical cycle should last around 15 minutes and occur between two and three times per hour.


A Clogged Air Filter

Your air conditioner's filter works hard to trap dust and other debris before it is distributed throughout your HVAC system. It's essential to replace your air filter once every three months or more often if your home is prone to airborne pollutants. A clogged filter prevents your home from having adequate airflow necessary for your HVAC system to perform efficiently.


Regular maintenance
, such as checking your air filter for clogs, is a smart and cost-effective way to prevent expensive repairs. If a clogged air filter is left unattended, the additional strain on the system can harm your air conditioner's internal components. By staying on top of your air filter maintenance, you can avoid these potential costs and keep your system running smoothly.


Low Refrigerant Levels

Every air conditioner requires a specific amount of refrigerant, or "coolant," to function correctly. As refrigerant moves throughout your HVAC system, it changes temperature and pressure quickly. Low refrigerant levels create an imbalance in the system, leading to short cycling.


Refrigerant lines and the evaporator coil can freeze without the correct amount of coolant, causing a pressure drop. This sequence of events can lead to the compressor overheating. But don't worry! Reliable Heating & Cooling has the tools and training to provide you with exceptional
