Heating systems (in fact, most HVAC equipment) can last a relatively long time when properly installed and maintained. However, there comes a time when you will need to upgrade or replace your old HVAC system. How do you know if it’s time to replace a furnace, especially if it hasn’t stopped working yet? Listed below are questions to consider before upgrading to a high-efficiency heating system.

How old is my heating system?

A well-maintained furnace can typically last between 15 and 20 years. When your heating system gets close to the 15-year mark it is a good time to evaluate whether the unit is truly working properly or if it has required frequent or significant repairs to run effectively. If this is the case, upgrading to a newer unit could be more cost-effective in the long run.

Is my old heating system working as efficiently as it used to?

If your furnace seems to be running non-stop, it could be because it is working harder to maintain the temperature set on your thermostat. An increase in your energy bills can also be a sign that your heating system is losing efficiency since the harder your furnace works the higher the heating bills rise.

When HVAC systems breakdown frequently it is usually a sign the system needs to be replaced.

How many times has my heating system broken down in the past few years?

When a system breaks down frequently, it is not running properly. Blowing cold air and concerning smells are common concerns. According to Consumer Reports, it is recommended that you upgrade your furnace if repair costs exceed 50% of the cost of a replacement.

Is my home comfortable?

If you have noticed temperature fluctuations and aren't satisfied with the quality of your comfort, this can be a sign that your heating system needs upgrading. One of the many benefits of energy-efficient units is their ability to provide consistent temperatures.

Is my old system still safe to use?

If there is a possibility that the answer is “no”, you may want to have a consultation with an expert. It's better to be 100% sure your heating system is safe to use than to guess. Any heating system potentially exposing you and your family to carbon monoxide needs to be replaced as soon as possible. Another helpful way to know if your furnace or other heating system is safe is to get an indoor air quality test. Among other air quality benefits, this test can measure the levels of toxic particles that may be present and help identify the source.

Updated HVAC systems improve the property value and are appealing to new homeowners.

Moving anytime soon?

If you intend to sell your home, updated HVAC systems greatly improve your property value.

Having a professional heating contractor size your furnace is important. An oversized system is likely to cycle on and off too frequently which results in more repair calls and an undersized furnace tends to run constantly in an attempt to heat your home, which greatly increases your energy bills.
