Expert AC Installation in the South Suburbs

When your old air conditioner is beyond repair or costing you too much in energy bills, it is time for an upgrade. J.D. HARPS, Inc. provides professional air conditioning installation and replacement across New Lenox and the surrounding areas. We focus on proper sizing and flawless installation to ensure your home stays cool for years to come.

When to Consider an AC Replacement

It can be tough to decide between a repair and a total replacement. We usually recommend a new system if:

  • The system is over 15 years old: Older units use R-22 Freon, which is obsolete and extremely expensive to recharge.
  • Repairs are too costly: If a repair costs more than half the value of the system, replacement is the smarter financial choice.
  • Poor energy efficiency: Upgrading to a modern, high-SEER unit can drastically lower your summer cooling bills.

Proper Sizing Matters

The most important day in the life of your air conditioner is the day it is installed. If an AC unit is too large for your home, it will short-cycle and leave your house feeling humid. If it is too small, it will run constantly and drive up your electric bill. We take the time to properly assess your home to recommend the exact capacity you need.

My 76yr. old Father's air went out just day's before a forecasted heat event. Mark and crew were able to install a new system before it got too hot. They made my father's situation a top priority and re-worked their schedule to get him air condition, and keep him safe! I am beyond thankful for the care and empathy they showed him. If you want someone you can trust, this wonderful family owned company is who you need to call. Great value, honest, prompt and they stand behind their work. Thank you Cindy, Mark and Eric, your all life savers!!!!
