When is it Time for a New AC Unit? Understanding the Signs & The "$5000 Rule"
Deciding whether to repair your existing air conditioner or invest in a brand-new system can be a challenging decision. We're here to help you make an informed choice that’s best for your home and budget.
Is Your AC Showing its Age? Common indicators your system might need replacing:
- Frequent Breakdowns & Costly Repairs: If your unit requires continuous repairs, especially expensive component replacements, the costs can quickly add up, exceeding the value of the unit itself.
- Rising Energy Bills: An aging or inefficient AC unit works harder to cool your home, leading to a noticeable spike in your monthly energy consumption, even without increased usage.
- Inconsistent Cooling or Hot/Cold Spots: If certain rooms are always warmer than others, or if your system struggles to maintain a consistent temperature throughout your home, it indicates a decline in performance.
- Strange Noises or Foul Odors: Grinding, hissing, squealing, or persistent musty smells can all signal significant internal issues that often point towards the need for replacement.
- Unit is 10-15+ Years Old: While proper maintenance can extend an AC's life, most units begin to lose efficiency and become more prone to breakdowns after a decade of service.
- R-22 Refrigerant: If your system uses R-22 refrigerant (Freon), it’s becoming increasingly expensive and difficult to find due to federal phase-out regulations. Replacing an R-22 unit now can save you significant repair costs in the future.

Repair vs. Replace: Making the Smart Choice.
To help homeowners navigate this decision, we often refer to the "$5000 Rule." This guideline suggests that if the cost of your AC repair multiplied by the age of your unit (in years) exceeds $5,000, it's often more cost-effective to replace the system rather than continue with repairs. For example, a 10-year-old unit needing a $600 repair (10 x $600 = $6,000) might be better off replaced.
Beyond this rule, consider the long-term benefits of a new system, including enhanced energy efficiency, improved indoor air quality, quieter operation, and the peace of mind that comes with a new warranty. Our technicians will provide an honest, thorough assessment of your current system and offer clear recommendations, empowering you to make the best decision for your home.

Residential New AC Installation Costs & Your Savings Potential
The cost of a new AC installation can vary based on several factors, but at The Cooling & Plumbing Co, we believe in transparent pricing and maximizing your investment.

Frequently Asked Questions About New AC Installation
Q: What is the average lifespan of a new AC unit?
A: A new central AC unit typically lasts between 12 to 17 years with proper maintenance. Factors like climate, usage, and regular servicing can influence its longevity.
Q: How long does a typical new AC installation take?
A: Most residential central AC installations can be completed within 4 to 8 hours. More complex jobs, such as those requiring new ductwork or extensive system overhauls, may take 1 to 5 days.
Q: Does new AC installation include ductwork?
A: Not typically, unless specified as part of the project scope. New ductwork installation can be an additional cost if your home doesn't have existing ducts or if significant modifications are needed due to age, damage, or design issues. Our technicians will assess your ductwork during the consultation.
Q: Do I need a permit for AC installation?
A: Yes, most regions require permits for new AC installations to ensure safety and compliance with local building codes. Our licensed professionals handle all necessary permits as part of our comprehensive service.
Q: What does SEER rating mean and why is it important?
A: SEER (Seasonal Energy Efficiency Ratio) measures an AC unit's cooling output relative to its energy input over an average cooling season. A higher SEER rating indicates greater energy efficiency, which translates to lower energy bills and reduced environmental impact.
Q: Can I replace just my outdoor AC unit?
A: While possible in some specific, rare cases, it is generally not advisable to replace only the outdoor condenser or indoor coil. AC systems are designed to work cohesively as a matched set. Mixing old and new components can lead to inefficiencies, reduced performance, increased energy consumption, and can even void your manufacturer's warranty. We recommend replacing both units for optimal performance, efficiency, and longevity.
