When the summer sun hits full strength in New England, your air conditioner has one job: keep you cool. So when it feels like it’s running nonstop and the house still isn’t comfortable, it’s easy to get frustrated. The good news? Your system might not be broken — but it probably needs some attention.
1. It’s Just Really Hot Outside
First, let’s be fair to your AC. Most central air systems are designed to cool indoor air to about 20 degrees below the outdoor temperature. So if it’s 95°F outside, your AC may only be able to get your home down to around 75°F. That’s not a sign it’s broken — it’s just doing the best it can.
2. Your Air Filter Could Be Clogged
This is one of the most common reasons for poor performance. A dirty filter limits airflow, which means your system can’t pull in enough warm air to cool properly. If it’s been more than 60 days since you changed the filter — or if you’ve had construction or pets in the house — it’s time for a new one.
3. You Might Need a Tune-Up
Coils get dirty, refrigerant levels drop, motors wear out. Even a small issue can make your system work harder with worse results. An annual tune-up can help catch problems early and keep your system cooling as efficiently as possible.
4. It Might Be Undersized for Your Home
If you’ve added an extension, finished a basement, or updated windows or insulation, your system might no longer be the right size. An HVAC professional can do a load calculation to determine whether your unit is powerful enough for your space.
5. Duct Leaks Could Be the Culprit
Even if your AC is working fine, leaking or poorly insulated ductwork can mean cool air never reaches the rooms you’re in. This is especially common in older homes. A duct inspection can reveal whether sealing or re-routing is needed.
