How to Keep Cooling Costs Low During Pennsylvania’s Hottest Months

Pennsylvania summers can be hot, humid, and expensive—especially when your cooling system is running full blast just to keep up. But with a few smart strategies and the right HVAC support, you can stay comfortable without overspending. Here are some tried-and-true ways to lower cooling costs in Pennsylvania while keeping your home comfortable all season long.

Schedule Seasonal HVAC Maintenance Before Summer Begins

Spring is the best time to get your AC checked. When temperatures start rising, systems that haven’t been serviced are more likely to break down. A seasonal tune-up helps your air conditioner work at peak performance, reducing energy use and the risk of AC repairs. With professional AC maintenance from McCrea’s HVAC professionals, you’ll be ready for whatever heat waves Pennsylvania throws your way.

Upgrade to a Smart Thermostat for Better Temperature Control

Smart thermostats automatically adjust the temperature based on your habits and preferences, helping you conserve energy. According to ENERGY STAR, homeowners can save an average of 8% annually on heating and cooling bills by using a programmable thermostat. McCrea installs smart thermostats from top brands like Google Nest, Honeywell, and Ecobee—giving you options that balance comfort and savings.

Improve Home Insulation and Seal Air Leaks

Poor insulation and air leaks force your air conditioner to work overtime, wasting energy and money.

Here’s how to spot potential problem areas:

• Check for drafts around windows and doors: Use weatherstripping or caulk to seal gaps.
• Inspect attic insulation levels: Add more insulation if the current layer is thin or compressed.
• Feel for hot spots around baseboards or outlets: These may indicate air leaks in the walls.

Use Ceiling Fans and Shading to Support Your AC System

Ceiling fans don’t lower the air temperature, but they do make you feel about 4 to 5 degrees cooler. That means you can bump the thermostat up a few degrees without sacrificing comfort. Just remember to turn fans off when you leave the room to save energy.

Shading also makes a big difference. Keep blinds and curtains closed during the hottest parts of the day, especially on south- and west-facing windows. If possible, plant shade trees around your home to naturally keep the space cool. And when the heat’s at its worst, avoid using appliances like ovens that add extra warmth to your home.

Consider an Energy-Efficient AC Replacement If Your Unit Is Old

If your air conditioner is more than 10–15 years old, replacing it could drastically lower your cooling bills. Newer models come with higher SEER (Seasonal Energy Efficiency Ratio) ratings that indicate better performance and energy use. In Pennsylvania, a SEER rating of 14 or higher is recommended, though ENERGY STAR–certified systems are even more efficient.
