It’s a measure of what you are breathing in. With our homes becoming more energy-efficient due to higher construction standards and home improvements there is more chance of the air in your home becoming stale. This chart provided by the CDC shows air pollution in three groups.

At Southern Comfort Mechanical, we care about what you are breathing in and measure the air in your home in 6 defined areas.


Temperature is controlled by the thermostat and the capability of your HVAC to achieve the target. If a system is not meeting the target temperature, then it’s easy to see the issue and call.


Humidity is driven by your HVAC and its ability to remove moisture from the air in your home. 55% is the target range of relative humidity in your home. Anything over 60% is considered too high and anything below 45% is when any wood flooring can start to dry out. There is not much of an issue with low humidity in the DFW area, but in the summer months, high humidity can become problematic. Your HVAC unit is only one element that can impact humidity. Leaky ductwork or insulation can result in hot air entering your home and if not addressed can result in your HVAC unit not being able to reach your target comfort level.

Particle Size

Particle sizes are the airborne particles in the air around your home. The main source for particles in your home is from pets, dust, and pollen.


Volatile Organic Compounds are produced in the home from beauty and cleaning products. Other sources are new furniture, carpet, fresh paint, and burning candles. Odors are typically from pets or lingering smells from cooking that can still be detected the following day.

Carbon Dioxide

Carbon dioxide is added to the home by human activities. When we breathe, we all create carbon dioxide. Over time this builds up in the air in the home. Fresh air has a level of around 400 ppm (parts per million). In a typical home, the level is around 800 -1200 PPM with highs in the 2000 plus. Cognitive impacts can be observed at levels above 1200 ppm.

Carbon Monoxide

Carbon monoxide is a typical exhaust gas from a furnace. This is only a concern in winter when the gas in the furnace travels through a heat exchanger and out the flue pipe.



April Aire VentilationThere are many different approaches and options to improve air quality based on your issues and requirements. If you’re having temperature issues, we recommend a service call to fix the issues with your equipment or ductwork. In addition, sealing up or replacing leaking areas that are pulling moisture and or an air balance can address a hot or cold area in your home. Filtration improvements can help to remove particles from the air also. For carbon dioxide treatment, we can help add fresh air back into your home via a range of options, starting with a fresh air intake and monitor. Adding powered ventilation April Aire energy recovery ventilator (pictured) or a combined ventilator and dehumidifier unit can also be an effective solution. Lastly, for carbon monoxide, if the furnace is not exhausted out of the home correctly, this will allow a carbon monoxide leak into your home which can result in dizziness, nausea, vomiting, and shortness of breath. The only option is to repair the existing unit or replacement.



The MERV rating is an abbreviation for the Minimum Efficiency Reporting Value. The higher the rating, the smaller the particle size is trapped and higher filtration performance. A filter upgrade with a higher Merv rating such as an April Aire Filter with carbon added charcoal can be used to remove odors, although there are alternatives methods to remove odors via fresh air or air treatment. Our team can provide you with additional information to make a decision that’s best for you and your home.
