With the first frost just around the corner, it’s time for homeowners in Philadelphia to get their homes ready for colder weather. Prepping for the first frost can help prevent potential damage and keep your HVAC system in good working order, all while saving you from costly repairs later in the season. Here are five essential steps to prepare for the first frost:

1. Inspect and Clean Your Outdoor HVAC Unit

Before the cold sets in, take a moment to inspect your outdoor HVAC unit or heat pump. Remove any leaves, sticks, and debris that may have accumulated around the unit. The fall season often leads to a buildup of leaves and other materials that can obstruct airflow, causing the unit to work harder than necessary. Cleaning and clearing the area around your outdoor unit can help maintain efficiency and prevent unwanted shutdowns as temperatures drop.

DIY Tip: Use a garden hose to rinse off dirt gently, but avoid using high pressure, which could damage the unit's fins. If the unit is covered in grime or has bent fins, it’s best to call a professional to ensure a thorough, safe cleaning.

2. Wrap Outdoor Pipes and Faucets

Freezing temperatures can damage any exposed pipes, leading to cracks and leaks that might not be immediately visible. To prevent this, wrap outdoor pipes and faucets with insulated covers or foam pipe insulation. This simple step helps avoid the hassle of a burst pipe repair, which can become a much larger issue once temperatures consistently drop below freezing.

DIY Tip: Pipe insulation is typically available at hardware stores and is easy to cut and wrap. Make sure you secure it tightly to prevent moisture from seeping in. If any pipes look rusty or fragile, consider calling a plumber for further inspection.

3. Schedule a Furnace or Heat Pump Inspection

The first frost often means you’ll be switching on your heating system full-time. Scheduling an HVAC inspection now ensures that your furnace or heat pump is working efficiently and safely. An inspection includes checking for potential issues like faulty wiring, cracked heat exchangers, or dirty filters. The technician can identify and address any minor concerns before they escalate into full-blown breakdowns during the coldest days of winter.

Pro Tip: McCorry Comfort offers comprehensive furnace tune-ups in Philadelphia, designed to keep your system running smoothly and efficiently throughout the winter. An inspection can also extend your HVAC system's lifespan, so it’s worth considering if you haven’t had one in a while.

4. Seal Windows and Doors

Even a well-insulated home can lose warmth through small cracks around windows and doors. Sealing these drafts with weatherstripping or caulking can help your HVAC system work less to maintain a comfortable indoor temperature. This is a relatively easy project that can make a significant difference in both comfort and heating bills.

DIY Tip: For an added layer of insulation, consider using a draft stopper or heavy curtain on windows and doors that aren’t frequently used. These options are easy to put in place and can prevent a chilly draft from entering your home.

5. Clean and Replace Air Filters

Changing or cleaning your HVAC system’s air filters is another easy step to improve air quality and maintain system efficiency. Dirty filters can restrict airflow, making the system work harder to heat your home. Replacing filters monthly during the winter months will not only reduce strain on your HVAC but also keep your indoor air clean—essential for those colder months when windows are closed.

DIY Tip: Most HVAC systems use disposable filters that are easy to change out, but if your system uses a reusable filter, be sure to clean and dry it thoroughly before reinserting. Keeping a spare filter on hand is a good idea so you’re ready for quick replacements.

By following these five steps, you’ll be ready for the first frost in Philadelphia. These small preparations help safeguard your home and HVAC system for the colder days ahead, giving you peace of mind—and a cozy, warm home.
