If you’re like most people, you probably don’t think about your HVAC system until a problem arises, and at
that point, it can be almost impossible to ignore. So what do you do?
Perhaps you’ve already called a repairman and been told your unit is in need of service. Now you’re looking at
the estimate to fix it and wondering, should I repair my unit or replace it? It’s not always an easy decision to
make. The Armstrong Air professionals have
compiled these important considerations to help you through the process.
The average life expectancy of a furnace is 15–20 years.
If your unit is nearing the average life expectancy, you’ll need to weigh the repair cost against the
possibility that more repairs may be needed very soon, or even a complete replacement.
Equipment that is approaching the end of its life expectancy will typically be much less energy efficient
than today’s equipment. For example, compare 8–10 SEER on the
cooling side, and 68% AFUE for a furnace to modern products that
rate as high as 18 SEER and 95% AFUE and you’re looking at some substantial savings on your
monthly energy bills when considering a new unit.
Energy costs (gas, oil, electricity) have risen significantly in the last decade, and will likely continue
to do so. Consider the energy consumption of your unit and your potential savings over its lifetime.
There are often financial incentives for upgrading to a new
system, which can be an important factor in your decision.
Be sure to ask your independent Armstrong Air dealer what other incentives are
currently available in your market.
If there have been upgrades made to your home that improve its insulation and energy efficiency (new windows,
doors, insulation, roofing, sealing, etc.), then your current unit may actually be oversized or undersized for
A smaller unit would cost less and use less energy to run.
Conversely, your current unit may be too small and may be working harder and less efficiently than it
Research shows that water heating, air conditioning and heating account for more than 50% of domestic energy
use.* It’s good to know that modern equipment uses less energy and will reduce your carbon footprint.
Newly manufactured air conditioning units have changed to R410a
refrigerant, a much more environmentally friendly product than its predecessor, R22.
Consider choosing ENERGY STAR® heating and
cooling equipment to lower your energy footprint.
