Benefits to Replacement


If your heating and cooling system is over 10 years old and  it’s not performing as well as it once was, you may be thinking about your repair bill vs. upgraded needs. Is it too soon for replacement? Is repair your best choice in the long run, or would a newer, more efficient Lennox system offer you the function and dependability you’ve been looking for? When determining repair vs. replacement, there are many considerations.


Benefits to Replacement

Substantial Cost Savings

If your heating, ventilation and air conditioning system (HVAC) is more than 10 years old and repair costs are approaching 50 percent of the value of the system, a great deal of energy can be saved by upgrading to a newer, more efficient system. Depending on the Seasonal Energy Efficiency Ratio (SEER), upgrading could save you 20-40 percent on heating and cooling costs.

Use a furnace? Answering the repair vs. replacement question is easy. According to Annual Fuel Utilization Efficiency (AFUE) ratings, which measure furnace efficiency, systems from the 1970’s offer AFUE ratings of about 65 percent, while today’s models offer near total efficiency – 97 percent. That adds up to a lot of energy dollars.

Tax Incentives

In addition to energy savings that add up over the lifetime of your new system, available tax credits and incentives could save you up to a large percent of the cost of newer, high efficiency systems. Lennox products carry the ENERGY STAR label for your best options when considering repair vs. replacement.


Newer units come with a warranty, which help you save on repair costs should any issues arise.

Green Benefits

The U.S. Government and the Environmental Protection Agency (EPA) have mandated the phase-out of R-22 refrigerant by 2020 in an effort to protect the ozone. Upgrading to a R-410A system not only helps the environment, it helps you avoid the high costs of repairing an older system as supplies of R-22 are further cut each year due to the phase-out.

Comfort and Air Quality

The latest Lennox systems do a better job of controlling temperature and humidity, which reduces mold and mildew growth, improving both the comfort and air quality in your home.


No more waiting around in an uncomfortable home for repair services or hard-to-find parts for your old system.

Does repair make more sense for my system?

Newer Systems

For new or relatively new systems, it is likely that repairs make the most financial sense.

The 50 Percent Rule

If the cost for repair vs. replacement of your system is less than half of its value and you haven’t been suffering the need for monthly service calls to keep your system up and running, repair may be easier on your checkbook.


If you are planning on moving out of your  home in the near future and your system is still working, talk to your real estate agent to see whether either repair or replacement would be in your best interest.


If your system is neither old nor new — some simple maintenance service may help keep it going and make quick replacement unnecessary. Ask your technician if this is in your best interest, and if so, what you can do to get a few more miles out of your existing system.

Recognizing the Time for Repair vs. Replacement


When it comes to repair vs. replacement, the EPA and Department of Energy’s joint ENERGY STAR program recommend HVAC (heating, ventilation and air conditioning) systems older than 10 years old and furnaces or boilers older than 15 years old be replaced. Though these systems may last a few years longer, they will increasingly lose energy efficiency over time, costing you energy dollars.

Frequent Breakdowns During Peak Use

If your system can’t handle the demands on its performance during the hottest and coldest times of the year, or has broken down multiple times over the past several years, repairs may not be in your best interest. In some cases they can add up substantially over time, costing you more than investing in a new system.

Uneven Temperatures

Uneven temperatures are an indicator of a possible need for a heating and cooling upgrade.


If your system has to overexert itself to keep up with the heating and cooling demands of your home, it can become excessively noisy or turn off randomly. Establish and maintain a regular maintenance schedule to preserve the function of your system, including annual professional maintenance to prevent problems before they occur.
