Indoor Air Quality

Do I need new windows or doors?

Aging windows and doors can allow unwanted guests, air, or dirt into your home. In addition these openings are the primary means by which heat is transferred in and out of your home, depending on the heating & cooling season. We offer a wide range of windows and doors that seal your home tight from dirt, heat, and intruders small & large. Call Roberson Air Conditioning to audit your home's energy envelope.

What is the proper indoor humidity level?

An ideal humidity in a South Texan home is between 45-60%. Humidity can change based on many things like weather, home age, occupancy, kitchen & bathroom use, AC unit sizes, etc. Humidity levels can affect the health of the occupants and the home. Please call Roberson Air Conditioning for humidity based consultations. Consult your doctor for any medical advice.

What do I need to set my air conditioner to be comfortable?

ASHRE recommends homes be designed to meet 75 degree Fahrenheit during the cooling season and 70 degree Fahrenheit during the heating season. When the humidity is too high it can cause the temperature to feel warmer than it is, causing a sticky feeling throughout the home. Unbalanced air circulation or personal preference can also alter the comfort level at those temperatures. Ask Roberson Air Conditioning what you can do to make your home more comfortable. 

Do I need a humidifier?

In South Texas, a whole-home humidifier is rarely needed in residential homes. Room humidifiers can benefit the health and comfort of your home but are generally only needed during heating seasons.

Do I need a dehumidifier?

In South Texas, a whole-home dehumidifier is highly recommended to target comfortable humidity levels regardless of season. In addition, a dehumidifier can reduce the AC run time, increase the temperature set point, increase comfort, and reduce the need for cooling in the home.

Doesn't my Air Conditioner already dehumidify the home?

Yes, your AC does remove humidity from your home. However, an AC unit will only dehumidify when it is running. In South Texas, the largest humidity load is often in the off season when the AC is needed less frequently or not at all. Roberson Air Conditioning recommends adding a Whole-Home Dehumidifier to supplement the Air Conditioning system.

Should I have my air ducts cleaned?

Duct cleaning is not considered an annual maintenance item and is not recommended on most applications. Dirty ductwork can result in air leaks, improper filtration, rodents, or environmental factors. Proper AC & Heating maintenance and filter replacement avoids the need for duct cleaning. Furthermore, the average life expectancy of ductwork is 20-30 years. In most cases dirty ducts should be replaced allowing a better return on investment and a more efficient AC & Heating system.

Should I use a pleated filter or flat filter?

One inch Pleated filters are more restrictive, have more surface area, and collect smaller particles. Flat filters are less restrictive and smaller particles can pass through the fibers. Media filters can be thicker with more surface area allowing moderate restriction, longer life span, and better filtrations. Depending on the layout, alternate filtration, and style of your HVAC system will depend on the type of filter you need. These options range from a couple dollars to hundreds of dollars. Roberson Air Conditioning keeps common pleated, poly, & glass filters in stock. Call or text to find the right air conditioning & furnace filter for your home.

How often should I change my filter?

In South Texas, we recommend replacing one inch filter every month. A media filter can last between 6-12 months. Filter life can be affected by HVAC run time, temperature set point, return air location, weather, environment, and particulate count.

Can my unit filter viruses?

Viruses can be 6 times smaller than smoke particles and 600 times smaller than a grain of salt, making it very difficult to filter. In the HVAC industry, viruses are considered bioaerosols, a biological airborne contaminant. Just like mold spores and bacteria, they can be killed or neutralized with ultraviolet light (UV). We offer UV solutions that treat the air that travels through your HVAC system killing the living contamination. Call Roberson Air Conditioning to review your air treatment solutions.

What causes odors or smells in the home? Can they be removed?

Odors are very small particles or off-gasses that are emitted into the air which trigger your olfactory system (sense of smell). Some examples of common sources of household odors are smoke, bacteria, chemicals, furniture, biological products, animals, etc. Yes they can be removed by using filtration, ultraviolet treatment, & ventilation to remove, dilute, or neutralize household odors that are circulated through your HVAC system.
