Beat the Heat: Essential AC Preparation for New Jersey’s Record-Breaking Summers

New Jersey homeowners are facing a sobering reality: summers are getting hotter, longer, and more demanding on air conditioning systems. The annual mean temperature in New Jersey over the last century has increased 2.9°F. In general, summers are longer and hotter. With the 13 warmest years having occurred since 1990 and nine of New Jersey’s 11 hottest Julys dating back to 1895 having occurred since 2010, it’s clear that your air conditioning system faces unprecedented challenges each summer season.

The Growing Heat Challenge in New Jersey

Recent data reveals the extent of New Jersey’s warming trend. The average number of heat waves increased from 2.0 in 1994 to 4.1 in 2023, while the number of warm nights in New Jersey has been above average since 2000, with the highest 5-year average being the 2010–2014 period. According to climatology research by the U.S. National Oceanic and Atmospheric Administration, New Jersey has been the fastest-warming of all 50 U.S. states by average air temperature over a 100-year period beginning in the early 20th century, related to global warming.

This dramatic shift means your AC system must work harder and longer to maintain comfortable indoor temperatures. Without proper preparation, even the most reliable units can struggle during extended heat waves that have become increasingly common across the Garden State.

Essential Steps to Prepare Your AC System

Schedule Professional Maintenance

Experts recommend scheduling maintenance twice per year. These maintenance sessions usually take place directly before summer and winter prior to drastic changes in temperature. Professional maintenance is crucial because regular seasonal inspections prevent breakdowns and help your equipment last about 40% longer. More than 65% of residential HVAC systems are improperly installed, leading to poor performance and wasted energy.

A comprehensive tune-up includes inspecting and cleaning evaporator coils, checking refrigerant levels, testing electrical components, and ensuring optimal system performance. Keeping up with preventative maintenance can help you avoid potential breakdowns or AC emergencies on the hottest days of the year.

Replace and Monitor Air Filters

One of the simplest yet most important maintenance tasks is replacing or cleaning your air filters. Dirty filters restrict airflow, reducing your system’s efficiency and potentially causing it to work harder than necessary. During New Jersey’s increasingly intense summers, replace or clean your air filters every 30-60 days during heavy use.

Clean filters are especially critical when your system runs continuously during heat waves. Check and change the air filters (or clean them if applicable) regularly – and more often than recommended if your system is running nonstop. Clean HVAC air filters are essential for efficient cooling.

Clean and Inspect Outdoor Units

Your outdoor condenser unit bears the brunt of New Jersey’s summer heat. The condenser coils play a key part in keeping your home cool by transferring the heat from inside your home to outside. Located on the air conditioner’s condenser unit, it typically looks like a large metal box with grills along the sides. After you’ve turned off the power to the air conditioner unit, you can use a garden hose to spray away any dirt, grass clippings, or debris covering your condenser coils.

Regular cleaning is essential because if your air conditioner unit has been turned off and sitting idle for a few months, it may have collected dust or become covered in leaves. This debris can reduce the air supply to your air conditioner unit, forcing it to work harder to supply cool air to your home. Over time, the obstructed airflow can cause the unit’s motor to burn out faster.

Test Your System Early

Don’t wait until temperatures soar into the 80s to discover problems with your cooling system. You should test your air conditioner on a mild day to ensure everything is working properly. Early testing allows you to identify and address issues before the peak summer season arrives.

Optimize Your Home for Efficiency

Supporting your AC system with energy-efficient practices can significantly reduce strain during extreme heat. Sunlight blasting through your windows can increase indoor temperatures by 10–15 degrees, forcing your AC to fight harder to keep up. Keep blinds, curtains, or shades closed during peak sunlight hours (10 AM – 4 PM).

Additionally, use ceiling fans to help make you feel cooler, especially at night. While ceiling fans and stand fans don’t actually cool a room, they have what is known as a wind chill effect, making you feel up to 4 degrees cooler than the real temperature.

When to Call the Professionals

Given New Jersey’s increasingly demanding summers, having a reliable HVAC partner is essential.

The Cost of Preparation vs. Emergency Repairs

Investing in preventative maintenance and preparation is far more cost-effective than emergency repairs during a heat wave. Just getting annual AC maintenance can save you 15% on your monthly energy bills—and those savings add up by the end of summer. You’ll also save money because your AC technician will catch problems before they get serious, so you won’t have to shell out big bucks for expensive repairs down the road.

Prepare Now for Summer Success

As New Jersey continues to experience record-breaking temperatures and extended heat waves, proper AC preparation isn’t just about comfort—it’s about reliability, efficiency, and cost savings. Summer heatwaves in the United States are becoming more common, more intense, and last longer. That’s according to a report from the Environmental Protection Agency (EPA) using weather data collected for the last 60 years.

Don’t wait for the first heat wave to discover your system isn’t ready. Schedule professional maintenance, replace filters, clean outdoor units, and optimize your home’s energy efficiency now. With proper preparation, your air conditioning system can handle whatever New Jersey’s increasingly hot summers bring, keeping your family comfortable while managing energy costs effectively.

Remember, in a state that’s warming faster than any other in the nation, a well-maintained AC system isn’t a luxury—it’s a necessity for health, comfort, and peace of mind during the challenging summer months ahead.
