A Guide to Winterizing the AC Unit

November 23, 2022

With the summer heat over for the year, you may think all that’s necessary to do for your air conditioner is switch it off until spring returns. However, even as you begin using the furnace, it’s important to take precautions against rust, freezing, and other forms of damage winter weather can inflict on your AC. Here's a closer look at the risks and how you can guard against them.


Why an Air Conditioner Needs to Be Winterized

Snow and ice can penetrate the outdoor condenser unit. Though a small amount isn't a problem, accumulation can lead to rust and corrosion that will cause problems when you turn the system back on next year. Small animals and pests can also seek shelter in the condenser unit when the fan doesn't run for months at a time. Taking precautions against these issues will protect your investment and ensure your AC will be ready for use with minimal preparation in the spring.



Furthermore, these steps will extend the life span of your air conditioner, as less wear and tear on internal components will lead to fewer costly repairs and part replacements. Because a worn or damaged AC system typically requires more energy to cool indoor air, preventive maintenance will lower your monthly energy and maintenance expenses.

How to Prepare Your AC for Winter

To prepare your air conditioner for cold weather, turn it off and check the outdoor condenser, taking care to remove any twigs, leaves, or other debris that's gotten lodged around the unit. This will reduce the chance of damage and help prevent pests from infiltrating it.

A waterproof vinyl cover should be placed over the condenser to protect it from windblown debris and snow and ice, with the bottom 12 inches or so exposed to prevent excess moisture and mold growth inside. If the unit has suffered physical damage, call a professional for repair so that no rust develops over the winter.


Next, change the air filter. In most homes, the furnace and AC use the same filter, and when it's clogged, it will circulate dust and other allergens through the ductwork while making it more difficult for the system to maintain a forceful airflow. Throughout the winter, inspect the outdoor unit for incidental damage, and replace the air filter every month to ensure optimal heating performance and prevent dirt and grime from collecting on the AC.

Why Your Air Conditioner Runs More in August | Alpine

By Tom Markley • August 5, 2026
Have you noticed your air conditioner running longer in August, even when the temperature outside does not seem as high as it was earlier in the summer? You are not imagining it. By late summer, several factors can make your cooling system work harder to keep your Ohio home comfortable. Humidity Makes Your Home Feel Warmer Temperature is only part of the comfort equation. August can bring high humidity, which makes the air feel warmer and forces your air conditioner to remove both heat and moisture from your home. Because moisture removal takes time, your AC may run longer even when the outdoor temperature is not unusually high. Warm Nights Give Your Home Less Time to Cool Down When nighttime temperatures remain warm, your home may not have much opportunity to release the heat it absorbed during the day. Attics, walls, roofing materials and ductwork can hold onto heat. When the next day begins, your air conditioner may already be working against a warm house instead of starting fresh. Your AC Has Been Working All Summer By August, your cooling system may have already logged hundreds of hours of operation. A dirty air filter, debris around the outdoor unit or dust collecting on system components can gradually reduce airflow and efficiency. ENERGY STAR notes that dirty filters restrict airflow and cause heating and cooling equipment to work harder. Checking your filter and keeping the outdoor unit clear of grass, leaves and overgrown plants can help your system operate more effectively. Longer Run Times Are Not Always a Problem An air conditioner running for longer periods is not automatically a sign that something is wrong. Longer, steadier cooling cycles can help maintain a consistent temperature and remove humidity from the air. However, you may need professional AC service if your system: Runs almost constantly without reaching the thermostat setting Produces weak or warm airflow Makes unusual noises Causes a sudden increase in your electric bill Leaves some rooms much warmer than others Frequently turns on and off after only a few minutes Help Your AC Finish the Summer Strong Replace or clean your air filter when needed, keep the outdoor unit free from obstructions and avoid making large thermostat adjustments throughout the day.  If your air conditioner is running more than usual and your home is still uncomfortable, Alpine Heating, Cooling, Plumbing & Refrigeration can inspect the system and determine whether it needs maintenance or repair. We serve homeowners throughout Wayne, Holmes and Ashland counties from our Wooster, Ashland and Mt. Eaton locations.

Do You Need to Replace Your AC Because of New Refrigerant Rules?

May 20, 2026
If you’ve heard people talking about “new refrigerant rules” for air conditioners and heat pumps, you’re not alone. Homeowners are wondering if their current AC system is suddenly outdated or impossible to repair. The simple answer is no — you do not need to replace your air conditioner just because refrigerant rules have changed. What Changed With HVAC Refrigerants? The HVAC industry is moving away from higher-GWP refrigerants, including R-410A, and toward newer refrigerants with lower environmental impact. Under the EPA’s refrigerant transition rules, many new residential air conditioners and heat pumps manufactured after January 1, 2025 must use lower-GWP refrigerants. Existing systems can still be serviced, and parts used to repair existing systems are not subject to the same restrictions as new equipment. For homeowners, that means your current air conditioner or heat pump does not automatically need replaced. Can My Current AC Still Be Repaired? Yes. If your system uses R-410A, it can still be serviced. The bigger question is whether a repair makes financial sense. As older refrigerants become less common over time, certain repairs — especially refrigerant leak repairs — may become more expensive. That does not mean every older system should be replaced, but it does make the repair-versus-replace decision more important. When Should You Consider Replacing Your AC? You may want to consider replacement if: -Your system is over 10–15 years old -You are facing a major repair -Your AC has a refrigerant leak -Your energy bills keep climbing -Your home has uneven temperatures -Your system uses older equipment that is no longer under warranty If your system is newer, running well, and only needs a minor repair, replacement may not be necessary. Don’t Panic — Get Honest Advice The new refrigerant rules are a real change in the HVAC industry, but they should not be used to scare homeowners into replacing equipment before they need to. At Alpine Heating, Cooling, Plumbing & Refrigeration, we help homeowners understand their options clearly. Whether your system needs a simple repair, a refrigerant leak check, or a full replacement estimate, our goal is to give you honest information so you can make the best decision for your home.
