When is Air Conditioner Replacement Necessary?

We understand that buying a new air conditioner is not something you want to rush if there's a more economical option. However, there are instances when replacing an air conditioner is a much better idea than repairing it:

  • If the unit is approaching the end of its lifespan (typically 10-15 years), investing in repairs may only provide a temporary solution. 
  • If the repair costs are excessively high, it may be more cost-effective to replace the unit, especially if the repairs are frequent or if major components require replacement. 
  • If the air conditioner has low energy efficiency, upgrading to a newer model can result in long-term energy savings. 
  • If the unit consistently fails to cool the space effectively or if it requires constant repairs, a replacement may offer improved performance and reliability. 

Consulting with our Lake Forest AC installers can help determine the most suitable and cost-effective course of action based on the specific circumstances of the air conditioner.

Choosing the Right Air Conditioner for Your Home

Selecting the right air conditioner for your home is crucial for optimal comfort and energy efficiency. Our Lake Forest AC installation team can help you make the right choice by taking into account the following factors:

  • Cooling Capacity: We'll help you determine the appropriate cooling capacity (measured in BTUs) required for your space. The size of the room, insulation, and other factors impact this calculation. An undersized unit will struggle to cool effectively, while an oversized one may cycle on and off frequently, wasting energy.
  • Energy Efficiency: You'll want to consider air conditioners with high Seasonal Energy Efficiency Ratio (SEER) ratings. Higher SEER ratings indicate greater energy efficiency, resulting in lower operating costs and reduced environmental impact.
  • Noise Levels: Don't fail to consider the noise levels of the air conditioner, particularly if you plan to install it in a bedroom or living area. Look for models with low noise ratings to ensure a quieter operation.
  • Features: Determine the features you desire, such as programmable thermostats, remote control, multiple fan speeds, and sleep modes. These features can enhance convenience and comfort.
  • Maintenance Requirements: Consider the maintenance requirements of the unit. You will probably want a model with easy-to-clean filters and accessible components to facilitate regular maintenance.
  • Budget: Set a budget for your air conditioner purchase, including installation costs. Compare prices, warranties, and energy efficiency to find the best value within your budget.

With so many brands, makes, and models on the market, it can be difficult to know what kind of air conditioner to purchase. But with John Stevenson Plumbing, Heating & Air Conditioning, Inc. on your side, you can trust that we'll provide you with honest guidance. Our Lake Forest AC installers will ensure that whatever air conditioner you choose, it will meet your specific needs, provide efficient cooling, and enhance your indoor comfort.

Frequently Asked Questions
  • Should I replace or repair my AC unit?

    Many customers ask if they should repair a broken air conditioning unit versus a full replacement. Often, a well-maintained and newer AC unit will be able to be repaired depending on the issue. If it is a part under warranty, replacement of the part is a simple fix. However, if the AC is more than 10 years old, has not been regularly serviced, or is in need of a major repair, replacement is the best option. Our team will provide all available options for homeowners to consider.

  • What's a Pre-Installation Evaluation? Does My New A/C Need One?

    In short, yes. A first step is conducting an energy audit to determine the energy load for your home. Calculating the load tells the experts at John Stevenson Plumbing, Heating & Air how much heat your house gains throughout the day & what size air conditioner will work best to keep it cool. This is critical as most A/C installation issues stem from an improperly-sized air conditioning unit.

  • Is Your Home's Ductwork & Design Able to Handle a New A/C System?

    Often your old, existing ducts can’t handle the airflow of a newly installed air conditioner. Any upgrades to accommodate a new system will likely increase the cost to install an A/C unit, but will ultimately help you avoid costly, high energy bills & hot rooms in the future.

  • What Type of Central A/C Unit Should I Install?

    Here’s where the load calculation comes into play, as you want to pick the right size A/C unit to install – either too big or too small of an A/C unit can lead to costly repair or replacement down the road. Call the HVAC professionals at John Stevenson Plumbing, Heating & Air, they’ll know which A/C unit is perfect to install in your home at the lowest price.
