Should I Repair or Replace My AC?

Sometimes, AC repair is not possible or cost effective based on the age or condition of your system. Examples of situations where AC replacement is preferable over AC repair include:

  • AC system is more than 10 or 15 years old
  • Repairs would cost more than half of the system's current value
  • Your AC is old enough to still use Freon (now no longer in production)
  • Your AC constantly needs repairs regardless of its age 

If air conditioner replacement is necessary, John Stevensonwill remove your existing equipment, advise you on the best AC unit for your specific needs (including efficiency and with utility costs in mind), and install your new, energy efficient HVAC central air system.  

Homeowners depend on our HVAC products and services to reduce utility costs and provide cooler and cleaner air, while also keeping in mind our environment and global warming. Ask about our home maintenance program that covers plumbing, heating, and central air to prolong the use of your equipment and reduce any unexpected future costs or repairs.

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.
