What Are My A/C's Limits and Why Are They Important?

When it comes to taking care of your air conditioning system, it's important to understand what your system's limits are. As with most objects in life, pushing them past their limits can result in system failure and, sometimes, irreplaceable damage. As a homeowner, it's advisable to understand the limits of your HVAC system so that you can stick to running your system within them.

Understanding the 20 Degree Rule

Any HVAC professional can inform you that residential air conditioning manufacturers create HVAC systems that are capable of cooling a home up to 20 degrees Fahrenheit. This means that if your home is 90 degrees, your air conditioning unit could lower the temperature in your house to a maximum of 70 degrees. It's crucial to realize that this is just a general rule of thumb. Other factors will affect your indoor air temperature, such as the amount of home insulation you have installed.

How to Prevent Continuous Running of Your HVAC System

If you've ever tried to turn your home thermostat down to its lowest temperature setting, you know that it stops at 60 degrees Fahrenheit. That's a pretty chilly temperature to set your thermostat at, but let's assume that you do. Let's also assume that the indoor temperature is currently 85 degrees.

Following the 20 degree rule, your HVAC system will only be able to cool your indoor environment by 20 degrees. Doing the calculation, this means that your HVAC system will only be capable of getting your environment down to 65 degrees. Since your thermostat is set at 60 degrees, your home air conditioning system will continue to run.

This puts unnecessary strain on your HVAC system, which can cause premature wear of many of the parts. It's very common for your system to overheat when it's continuously running due to the set temperature being well below the actual indoor temperature.

Is a More Powerful System Possible?

When most people learn about the 20 degree rule, their first thought is whether or not they can purchase a more powerful air conditioning unit. The reality is that residential air conditioning units are not sold more powerful for a reason. They would consume an immense amount of energy to run. In addition, the air temperature that would blow out of the vents would be extremely chilly. This would make your home more frigid and uncomfortable.
