Spring: Preparing for Cooling Season
Pennsylvania's spring weather is unpredictable — warm days arrive quickly, and the first stretch of heat often catches homeowners off guard. Taking time in April or May to prepare your air conditioning system before temperatures climb can save you from an uncomfortable and costly emergency call during the first heat wave of the year.
Start with a fresh filter. A dirty air filter restricts airflow, reduces system efficiency, and can cause the evaporator coil to ice over. Check your filter every month during cooling season and replace it when it looks dirty — for most homes, that means every one to three months. If anyone in your household has allergies or asthma, consider a higher-MERV filter, though you'll want to make sure your system can handle the increased resistance.
Next, clear the area around your outdoor condenser unit. Over the winter, leaves, debris, and plant growth may have accumulated around or inside the unit. Gently brush off any debris, and trim any vegetation to maintain at least two feet of clearance on all sides. This ensures the unit can pull in air efficiently. Do not pressure-wash the coils without guidance — it's easy to damage the fins.
Schedule a professional tune-up. A trained technician will check refrigerant levels, clean the coils, inspect electrical components, test the blower motor, and verify that the system is operating as designed. This annual checkup catches small issues before they become expensive failures. WebSuite Your Way Test Site recommends scheduling your AC tune-up in April or early May before the peak season demand.
Summer: Keeping Cool Efficiently
Pennsylvania summers can be hot and humid. Here's how to keep your system running efficiently during peak cooling season:
- Set your thermostat to 78°F when home and raise it when away. Each degree above 72°F can reduce cooling costs by 3–5%.
- Use ceiling fans to increase perceived comfort — they allow you to raise the thermostat setting without sacrificing comfort.
- Keep blinds and curtains closed on south- and west-facing windows during the hottest hours of the day.
- Avoid running heat-generating appliances (ovens, dryers) during peak afternoon heat.
- Check your filter monthly. A system working harder in heat will move more air and fill filters faster.
- Watch for signs of problems: reduced airflow, ice forming on the refrigerant line, or the system running constantly without reaching the set temperature. These are signals to call for service.
Fall: Preparing for Heating Season
As temperatures drop in October and November, it's time to shift attention to your heating system. Don't wait for the first cold night to test your furnace or heat pump — that's when technicians are busiest and wait times are longest.
Turn on your heat before you need it. Run your system on a warm day when you can open windows if needed. This lets you identify any strange smells (dust burning off is normal in the first run; a persistent burning smell is not), unusual noises, or failure to reach temperature while you still have time to schedule a non-emergency service call.
Replace the filter at the start of heating season. A fresh filter sets you up for efficient operation through winter. Also check that vents throughout the house are open and unobstructed by furniture or rugs.
Schedule a professional heating tune-up. A technician will inspect the heat exchanger (critically important for gas furnaces — a cracked heat exchanger can allow carbon monoxide to enter your living space), check the burner, test safety controls, and clean the system. Test your carbon monoxide detectors and replace their batteries. If you have a heat pump, fall is the right time to inspect the refrigerant levels and defrost controls that are essential for cold-weather performance.
Winter: Cold-Weather Operation and Emergency Preparedness
During winter, keep the following in mind:
- Maintain a minimum indoor temperature of 55°F even when away or on vacation to prevent frozen pipes.
- Keep exterior heat pump units clear of snow and ice accumulation. Do not chip ice from the unit — allow it to defrost naturally or call for service. Some ice on the coil during cold weather is normal; a fully iced unit is not.
- Know where your emergency shutoff is for your heating system and fuel supply.
- If your system stops working during cold weather, call WebSuite Your Way Test Site for emergency HVAC service.
- Change your filter mid-winter if the system has been running heavily.
