Our Furnace Installation Process

A lot more goes into the furnace installation process than simply plugging it in and turning it on. The expert Nazareth furnace installers at Jack Lehr conduct Manual J calculations to make sure your furnace is properly sized for maximum comfort and efficiency. We install your new heating system according to Quality Installation guidelines where applicable. This means your new furnace will be:

  • Correctly sized to meet your home or business’s needs
  • Properly connected to a well-sealed duct system
  • Efficiently operating with sufficient airflow

All of our furnace installations include a thorough start-up of the equipment and a review of the installation checklist in your Nazareth area home or office. Our job is not done until you initial that our full start-up, checklist, and explanations of the HVAC system are completed to your satisfaction.

Benefits of Installing a New Furnace from Jack Lehr

The biggest benefit of new furnace installation is that most systems are much more energy efficient than models that are even just five to 10 years old. While a furnace should last 12-15 years, older models did not have as strict standards (set by the Department of Energy) for fuel efficiency. Furnace fuel efficiency is measured in AFUE, or annual fuel utilization efficiency, written as a percentage. Since 2013, the minimum AFUE rating for gas furnaces in the state of PA is 90%. Likely, a new system will automatically be more fuel efficient than the system you had installed eight or 10 years ago—meaning you could save hundreds on your annual energy costs.

In addition, new furnace installation provides for:

  • Dependable heat all season long
  • Increased home comfort
  • Quieter operation and more modern technological improvements
  • Lesser chance of costly repairs this winter

Another way to increase your home comfort and savings is to sign up for a furnace maintenance agreement. Not only will you extend the life of your new furnace and help prevent mid-season breakdowns, you’ll also receive several other perks when you’re enrolled in our Preferred Client Plan:

  • Priority service, including 24-hour emergency service
  • Free or discounted repairs
  • Discounts on parts and labor
  • Two-year warranty on repairs
  • And more

Great Service




We chose Jack Lehr due to a prior good experience with Ben who worked with us on our Air Cond system. Ben was very efficient and we appreciated the fact that he took the time to answer our questions.This time we had an electrical issue and the technician (Caleb) performed in the same manner. It was very reassuring to watch him work and also to have him tell us what he was doing, recommendations for some of our issues, and answering any of our questions.
