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.
