Frequently Asked Questions

  • 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.

Trained technicians can come to your house to give you an upfront, transparent installation report, as well as consult you on what unit your home will need.
