How to Know It’s Time for AC Replacement: Key Signs to Watch

Your air conditioner works hard to keep your home cool, but like all appliances, it has a lifespan. Knowing when to replace your air conditioner can save you from unexpected breakdowns, high energy bills, and costly repairs. At Aelott Air Conditioning, we help homeowners in San Marcos, CA make smart, timely decisions about AC replacement.

Here are clear signs that it might be time to replace your air conditioner:

  • Frequent Repairs: If you’ve needed multiple repairs in the past year, investing in a new, reliable system is often more cost-effective than continuing to patch an aging unit.
  • Rising Energy Bills: Older systems become less efficient over time. A noticeable increase in your energy costs often signals that your AC is working harder than it should.
  • Inconsistent Cooling: Hot and cold spots in your home or uneven airflow could mean your AC system is no longer capable of keeping up with your cooling demands.
  • Strange Noises or Odors: Loud banging, grinding, or foul smells are signs of mechanical issues that may not be worth repairing.
  • Outdated System: If your air conditioner is more than 10–15 years old, it likely lacks modern energy-efficient technology. Replacing it with a newer model can dramatically lower utility bills and improve comfort.
  • Uses R-22 Refrigerant: If your system still uses R-22 (Freon), it's time to replace it. This refrigerant has been phased out, and recharging an old system is both costly and environmentally unfriendly.

If you’re experiencing any of these signs, don’t wait for a complete system failure. Reach out to Aelott Air Conditioning today for a free installation estimate and let us help you find the perfect, energy-efficient replacement.

How to Select the Right AC System for Your Home

Choosing the right air conditioning system for your home is one of the most important steps in ensuring comfort, efficiency, and long-term savings. At Aelott Air Conditioning, we help guide you through the selection process, focusing on performance, cost-effectiveness, and innovation. Here are key factors to consider when selecting your new AC unit:

Size Matters

An oversized unit will cycle on and off too frequently, wasting energy and putting unnecessary strain on components. On the other hand, an undersized unit will struggle to cool your home, running constantly and driving up your energy bills. We perform precise load calculations to ensure the perfect fit for your home.

Energy Efficiency (SEER Rating)

A higher SEER (Seasonal Energy Efficiency Ratio) rating means lower energy usage and smaller utility bills. Modern units offer SEER ratings between 14 and 26. We recommend choosing the highest efficiency model that fits your budget to maximize long-term savings.

Type of System

  • Central Air Conditioning: Perfect for larger homes, central air systems efficiently cool your entire house through a network of ducts, offering consistent temperatures, better humidity control, and seamless integration with smart thermostats for convenience.
  • Ductless Mini-Splits: Ideal for homes without ductwork, these systems provide customizable, room-by-room cooling and heating solutions, delivering high energy efficiency, whisper-quiet operation, and precise temperature control where you need it most.
  • Heat Pumps: Versatile and energy-efficient, heat pumps offer both cooling in the summer and heating in the winter, making them an excellent year-round solution for homeowners looking to reduce energy costs and carbon footprint.

Additional Features

Consider smart thermostats, variable-speed compressors, and advanced filtration systems to enhance performance and indoor air quality.
