Do I Need a New AC? 6 Signs It’s Time to Replace Your Air Conditioner
Suffolk County summers can be brutally hot and humid, so when your air conditioner isn’t doing its job, your whole home suffers. But how do you know when it’s time to replace your air conditioner — and when a repair might still be worth it?
Our HVAC experts have seen it all, and we’re here to help you recognize the warning signs. In this guide, we’ll walk you through the top 6 indicators that it’s time to upgrade to a new AC system.
Your AC Is More Than 10–15 Years Old
Most air conditioning systems are built to last 10 to 15 years. If your system is approaching this age (or already past it), chances are it’s operating at reduced efficiency. Older units are also more prone to breakdowns, use outdated refrigerants, and lack the features of modern models.
If your AC is over a decade old, it may be time to plan for a replacement before you’re stuck without cool air in the middle of a heatwave.
Frequent and Costly Repairs
Are you calling your HVAC technician every season for a new issue? Repairs can add up quickly. If the cost of fixing your unit is 50% or more of the price of a new system, it often makes more financial sense to upgrade.
A new system will run more efficiently, reliably, and come with a warranty — saving you time, stress, and money.
Higher Energy Bills Without Higher Usage
A sudden spike in your electric bill (without using more energy) is often a sign that your AC system is working too hard. Older systems lose efficiency over time, especially if they haven't had consistent maintenance.
Modern units with high SEER ratings are far more energy-efficient and can drastically lower your monthly utility costs.
Uneven Cooling or Hot Spots in Your Home
Do some rooms feel like a sauna while others are comfortable? Uneven cooling can mean your system is no longer powerful enough or that your ductwork is deteriorating.
Upgrading to a new system — or considering ductless mini splits — can improve comfort in every room.
Strange Noises, Odors, or Leaks
Banging, buzzing, grinding, or clicking noises are never good signs. Neither are foul smells or signs of leaking refrigerant or water around your unit. These symptoms could mean anything from a failing compressor to mold inside the system.
If the issue is serious and recurring, replacement is usually the safest and most cost-effective option.
Your AC Uses R-22 (Freon) Refrigerant
Older systems often use R-22, a refrigerant that has been phased out due to environmental concerns. It’s no longer being manufactured, and repairs involving refrigerant are extremely expensive.
If your system uses R-22, replacing it with a modern, eco-friendly unit is not only better for your wallet — it’s better for the environment.
