Summer Prep Tips to Keep Your Home Cool Without Overworking Your AC
If you’ve been searching for air conditioning service near me as summer approaches, you’re not alone. Homeowners across Brownstown, Elizabethtown, and all of Lancaster County start noticing the same thing every June: the house feels warmer, the AC runs more often, and the electric bill climbs before the real heat even arrives.
Good news: a little targeted preparation goes a long way. This guide covers the practical steps that make a real difference, as well as the warning signs that indicate it’s time to call a professional.
Your family’s comfort is our family’s business, and that philosophy has driven every job at Ressler & Mateer since 1970.
This sounds too simple to matter. It matters more than almost anything else.
A clogged filter forces your AC to fight resistance on every cycle. Airflow drops. The evaporator coil can’t push cold air efficiently into your living spaces. In bad cases, the coil freezes entirely and the system shuts down.
For most Brownstown-area homes, a standard 1-inch filter needs changing every 30 to 60 days during the cooling season. Pets or allergy sufferers in the house? Closer to 30 days. Hold the old filter up to a light source. If you can’t see through it, it was overdue before you pulled it.
The condenser sits outside and releases heat pulled from your indoor air. When the fins and coils clog with grass clippings, cottonwood seeds, or dirt, they can’t shed that heat efficiently. The refrigerant can’t compress properly and the whole system strains.
Turn off the power at the disconnect box, clear debris from around the unit, and gently rinse the fins with a garden hose from the inside out. Do not pressure-wash it. The fins are thin aluminum and will flatten.
If the unit hasn’t had a professional cleaning in two or more years, or if it’s running longer than usual to reach your set temperature, schedule a service call.
An annual air conditioning tune-up is the single most important thing most homeowners skip. It’s preventive maintenance, not a sales pitch, and it’s the difference between a breakdown in July and a system that runs all summer without trouble.
A standard tune-up covers:
Schedule in April or May if possible. Once the heat hits, HVAC companies book out fast. If you’re looking for reliable air conditioning service near Brownstown, PA, our team at Ressler & Mateer has been doing this work for over 50 years.
Setting your AC to 68 degrees on a 92-degree day and leaving it there is one of the fastest ways to wear out a compressor. The system runs almost continuously to hold that temperature.
A programmable or smart thermostat helps. Let the temperature rise a few degrees while the house is empty, then cool it down about 30 minutes before people return. Around 76 to 78 degrees when you’re home gives the system a workload it can handle without strain.
Older homes in the Brownstown area, including the farmhouses and colonial-style properties throughout Lancaster County, often have gaps around windows, exterior doors, and attic hatches that let hot air seep in all day. Weatherstripping and door sweeps are inexpensive fixes with a fast payback.
Close blinds or thermal curtains on south- and west-facing windows during peak sun hours, roughly 10 a.m. to 4 p.m. The U.S. Department of Energy estimates medium-colored blinds reduce solar heat gain by about 45 percent. That adds up on a 95-degree afternoon in central Pennsylvania.
None of these issues below resolves on its own. Call for air conditioning service near you if your system is:

Once a year is the standard recommendation. The ideal time is spring, before the cooling season begins. Annual service keeps the system running efficiently, catches small problems before they grow, and extends the life of the equipment.
A standard tune-up covers refrigerant level checks, coil cleaning, electrical connection inspection, capacitor testing, thermostat calibration, condensate drain cleaning, and airflow measurement. Specifics can vary by company and system type.
A dirty air filter is the first thing to check. Beyond that, common causes include low refrigerant, a frozen evaporator coil, a clogged condenser, or a failing compressor. If the filter looks fine and the problem continues, call a technician.
Most energy experts recommend 76 to 78 degrees Fahrenheit when you’re home and 82 to 85 degrees when the house is empty for extended periods. These settings give the system a manageable workload on hot days.
The average lifespan is 15 to 20 years with regular maintenance. Systems that go years without service tend to fail earlier. If your unit is approaching the 15-year mark, get a professional assessment before committing to another major repair.
Yes, significantly. Gaps around windows, doors, and ductwork let conditioned air escape and hot outdoor air enter. The result is a system that runs harder and costs more without delivering better comfort. Sealing leaks is one of the highest-return comfort improvements you can make.
