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.

  • Why Isn't My Home Getting Warm Enough?
    There are a few reasons why your furnace may not be warming your home efficiently or evenly. One of the most common reasons is a leak in the ducting. If there is a small hole or the ducting is improperly installed, it could leak out warm air and cause the air pressure to drop and the system then provides inadequate heating. Additionally, dirty filters will also cause a restriction in airflow making the system work harder. This can lead to a broken system, which is why regularly changing and/or cleaning your air filters is so important.
