When it Comes to Your Cooling and Heating System – Should You Repair or Replace?

Does it seem as though your air conditioning doesn’t work as efficiently as it used to? With the summer months approaching, the last thing you want is for you and your family to be stuck in an uncomfortable environment.

Your cooling and heating system is one of the most important components of your home, and the choice between replacing and repairing can be a big one. Because of this, it’s important to evaluate each option.

Cost is an immediate consideration—the up-front price of repairs will likely be less than installing a new model. But consider the age of your current system and the relative cost of repairing it: If your existing equipment is more than 10 years old and the cost of repairs is more than one-third of what a new system would cost, it may make more sense to replace it. (And if the repair bill approaches 50% of the cost of a replacement, an upgrade may be a better choice).

If repairs are less than one-third of the replacement cost and your system is less than 10 years old, it may have many productive years ahead. Even 25- year-old equipment can still keep your home comfortable with the proper maintenance and attention.

Of course, an older system is more likely to require repair going forward, so factor in the potential costs and inconvenience of keeping up an aging system.

It’s also important to look beyond the up-front price tag to the cost of the system over time. More energy efficient heating and cooling systems mean lower monthly utility bills, leading to savings you’ll reap year after year for the life of the system.

You can understand the heating efficiency of a furnace by its Annual Fuel Utilization Efficiency (AFUE), which measures the percentage of energy that’s actually used to heat your home. Most new furnaces have an AFUE of 80% or more, and the highest AFUE available is greater than 98%. If your current system is less than 80% efficient, you could save considerably on your monthly utilities with an upgrade.

For cooling with an air conditioner or heat pump, the measurement is Seasonal Energy Efficiency Ratio (SEER). A higher SEER rating means greater energy savings. 13 SEER is the minimum currently required, and models in the mid 20s are available. Upgrading to a higher SEER rating means energy savings over the life of the system. For heat pumps in heating mode, look for a Heating Seasonal Performance Factor (HSPF) of over 10 for greater efficiencies. Heat pumps are available with HSPF of up to 13.

Finally, installing a more efficient system will help with the energy costs, but if you are considering a geothermal system, it may also qualify you for tax credits of up to 30% of the installation.

Ultimately, your decision comes down to evaluating the short-term costs versus the long-term value, and making sure that you understand the impact of energy savings over the life of the system while weighing concerns, such as air quality.
