When Should You Replace Your Air Conditioner and Furnace?

When it’s time to consider replacing your air conditioner and furnace, it’s crucial to make informed decisions about your home comfort system. At Metro Plumbing, Heating, and Air, we understand the significance of this decision. With our local expertise, we provide valuable insights tailored to your needs.

Drawing from years of experience and numerous service calls within our community and across the heating and air conditioning industry, we’ve gained valuable knowledge and statistics. This wealth of information positions us to guide you through the process of upgrading your aging home comfort system. We recognize two primary scenarios that often signal the necessity of replacing your furnace and air conditioner.

Saving Utility Costs

Reducing utility costs is a significant benefit of investing in a new heating and air conditioning system. A high-efficiency system, known for its effectiveness, can potentially cut your utility expenses by up to 75%. To illustrate, let’s consider the example of upgrading from a 6 SEER air conditioner to a 13 SEER system. Determine your SEER ratio by dividing 6 by 13. This ratio is then used to identify your potential utility savings, providing a practical way to understand the financial advantages of a more efficient system.

Saving Utility Costs

Consider this scenario: imagine you currently possess an 8 SEER air conditioner in Chattanooga, TN. With the average July utility bill in Tennessee at $185, assuming the air conditioner contributes to 50% of that, you’re spending $92.50 to cool your home in July. Now, if you were to upgrade to a 16 SEER air conditioner, the potential savings could amount to $46.25 during similar months. (8 / 16 = .5 and $92.50 x .5 = $46.25)

Repair Cost


Consider this scenario: Suppose you own a 10-year-old air conditioner in Chattanooga, TN, and our technician discovers the need for a hard start kit, which comes with a $253 price tag. In this case, we would recommend proceeding with the repair. However, if the technician identifies a requirement for a new condenser fan motor, and the repair cost is $667, our recommendation would lean towards replacing your entire system. Why? We’ve conducted thorough studies to conclude that, in the long run, maintaining your old system could incur higher costs compared to investing in a new and more efficient system.

Accurate Costs of Repairing a Maturing System

When confronted with a malfunctioning mechanical system, the instinct is often to opt for repairs as a cost-effective solution. However, a crucial factor tends to be overlooked in this decision-making process: the genuine cost of repeatedly repairing an old system versus replacing it. All mechanical equipment has a projected lifespan, beyond which its reliability diminishes, and efficiency declines. While delaying the replacement of an aging system might appear as a short-term money-saving tactic, it’s vital to grasp the long-term financial implications.

  1. Rising Repair Costs: As a system ages, the likelihood of breakdowns increases. Frequent repairs can accumulate not only in immediate costs but also in the inconvenience and discomfort caused by recurrent breakdowns.
  2. Diminished Efficiency: Older systems are generally less energy-efficient, resulting in higher utility bills. Modern systems, equipped with the latest energy-saving technology, can significantly cut ongoing energy expenses.
  3. Decreased Comfort: Aging systems often struggle to maintain consistent indoor temperatures and desired comfort levels. This can lead to discomfort for you and your family, affecting your overall quality of life.
  4. Environmental Impact: Inefficient systems consume more energy, contributing to higher carbon emissions and environmental damage. Upgrading to a newer system not only reduces your carbon footprint but also supports sustainability efforts.
  5. Opportunity Cost: Money spent on frequent repairs could be better invested in a new, efficient system that provides reliable performance and long-term savings.

Remember, it’s not a question of if you’ll need to replace your existing system, but rather when. Postponing the inevitable replacement can ultimately cost you more than upfront investment in a new system. The longer you delay, the more you’ll spend on repairs, energy bills, and compromised comfort.
