Maintenance
How often should I service my AC system?
It is best to service your air conditioning systems at least once per cooling season. Checking refrigerant levels, drain lines, and air flow are a few important items that can affect the efficiency, operation, and safety of your AC unit. Contact Roberson Air Conditioning to hear more about our Family Service Agreement (FSA).
What is a Service Agreement and what does it do for me?
Service Agreements are prepaid preventative maintenance plans that help prolong the life of your unit, verify the proper operation of your HVAC unit, and address any potential failures before the cooling and heating seasons. Roberson Air Conditioning has a maintenance plan that we call the Family Service Agreement (FSA). We are a family owned and operated company that wants to treat you like family. Ask us what benefits you received with this VIP service.
How often should I service my Heat system?
It is best to service your gas furnace or electric heat at least once per heating season.

Do I need to add freon to my AC unit?
Refrigerant (also known as freon) is not a consumable, like the gasoline in your vehicle. Once the refrigerant circuit is sealed, evaluated, and charged to manufacture specification it should not need to be balanced. However, there are a couple exceptions for needing to add or remove refrigerant from a system. The most common is a leak in the drier, component, coil, or tubing. Others can be changes in the HVAC airflow, incorrect commissioning, improper charging methods, or replacement of a component in the refrigerant circuit. You might have an incorrect refrigerant charge if the unit does not cool well or freezes up. Call Roberson Air Conditioning to schedule a diagnostic appointment today.
Where should my AC be draining?
AC systems create moisture or condensation as a byproduct of cooling. The evaporator coil has a primary pan built into the box that collects water. That pan is connected to a pipe that drains into your home’s plumbing or terminates outside in a lower area like a flower bed, french drain, etc. Units located in the attic should have an emergency or secondary pan underneath the box to collect water in the event the primary pan is cracked, clogged, or overflowing. This pan usually drains outside from a high place as well through a soffit, above a window, onto a patio, etc. If you are having water overflow or dripping from a soffit or ceiling outside please call Roberson Air Conditioning immediately to avoid any water damage to your home and property.
How close can I place plants next to my outside AC condenser?
The outside condenser has a fan on top and coils around the unit that cools the refrigerant after it is compressed. If the condenser coils are clogged or covered it will cause the AC unit to overwork, cost more to operate, damage the unit, or stop working completely. Keeping weeds, plants, vines, structures, grates, or mesh panels away from the outside AC unit can help keep your system cooling and trouble free. Roberson Air Conditioning can do an in depth service check to clean your AC unit and make sure it runs at peak performance.
New Unit
How do I know if I need a new air conditioner?
The industry shows that AC units last an average of 13 years. If properly maintained and installed, you can prolong the life expectancy.
How do I know if I need a new heater?
Gas Furnaces last an average of 15-30 years. Heat Pump units have a similar life expectancy to AC units averaging 13 years. Proper maintenance and installation can prolong the life of any unit.
What size Air Conditioning System do I need?
Residential air conditioning systems are sized in accordance with The Air Conditioning Contractors of America (ACCA) Manual J Calculations. Doing a Manual J will insure the proper BTU/h of cooling and heating the home needs. The energy envelope of the home consists of, but is not limited to, the square footage, home age, insulation, build quality, occupancy, doors, and windows. These are just a few of the items considered when an energy & load calculation is performed on the home.
Which Air Conditioning system is right for my home?
The best system for your home is an AC unit that is the correct size for the home, installed in accordance with local code, and properly commissioned to meet manufacturer specifications.
What type of heating and air conditioning system should I get?
There are many types of HVAC equipment. Common residential homes use Forced Air Cooling & Heating. In South Texas, residential AC units are always electric direct expansion; while heat units can be electric resistance, natural gas furnace, propane gas furnace, or electric direct expansion heat pump. Consult with Roberson Air Conditioning for your specialized heating and cooling system.
What is the best way to heat and cool my home?
The best way to heat your home is with central air conditioning and heating. There are also options for whole-home mini split hybrid heat pump systems. Consult with Roberson Air Conditioning for your specialized heating and cooling system.
Can you add a Heating & Cooling system to a building or home that doesn't currently have one?
Yes! With a wide range of equipment, sizes, and experience Roberson Air Conditioning can install heating & cooling to ANY structure. We have options for environmental human comfort in your home, rental property, business, or extra game room. We also can provide commercial process equipment conditioning for server rooms, storage facilities, or electrical rooms.
Do I need a Variable Capacity AC Unit?
Variable Capacity AC Units can increase the comfort and efficiency of your home. Also known as 2-Stage, multi-stage, and variable stage units, they will adjust output to target the perfect temperature of your home while reducing your energy bill. This results in lower humidity, more even temperatures, better comfort, and less hot and cold spots. Consult with Roberson Air Conditioning for your specialized heating and cooling system.
What is better to heat my home: Gas, Electric, or Heat Pump?
It depends on your electrical and gas utility connections at your home. For energy usage, Natural Gas is always the prefered method of heating and for customers with Propane or electric only utility connections Heat Pump is the best option. For equipment & repair cost, Electric Resistance Heat is the most simplistic and economical. For safety, all units meet UL code and have proper safety cutoffs and precautions in place to make heating your home very safe. Consult with Roberson Air Conditioning for the best heating system for your home.
What is a Heat Pump?
Heat Pumps provide both heating and cooling. A Heat Pump is basically an Air Conditioning that can run in reverse. The unit is equipped with a reversing valve that switches the flow of refrigerant allowing the unit to alternate between heating & cooling the space. Heat Pumps can be limited on output and operation during low temperature events. For this reason most Heat Pump units are installed with backup electrical resistance heat to supplement the loss in heat pump capacity. Consult with Roberson Air Conditioning for your specialized Heat Pump system.
What is SEER and SEER2?
SEER & SEER2 are US Department of Energy (DOE) efficiency ratings of AC units running a full capacity (100%). The higher the rate the more efficient the air conditioner is and is comparable to MPG rating on your vehicle. Technically, it is the total heat removed from the conditioned space during the annual cooling season, divided by the total electrical energy consumed by the air conditioner during the same season. Currently systems are rated with SEER. SEER2 is the updated rating system that will be rolled out in 2023.
What is a common efficiency for Air Conditioner Systems? What do I need?
Currently the minimum efficiency for residential units is maintained at 14 SEER. Energy Star rated systems start at 15 SEER. High efficiency 16+ SEER units can save significant energy, make the home more comfortable, and be an investment in your home. Roberson Air Conditioning offers units up to 25 SEER, please ask us for a return on investment analysis and see what heating and cooling system is best for you.
Which brand is the best one to buy? Is there one brand that's better than the rest?
In our professional opinion the design, installation, commission, and continual service of a system is MORE important than the brand name. Out of the hundreds of HVAC brands there are only a few major manufactures in the world. Let’s be honest, your desire for an easy to use, trouble free unit is at the top of your list. A trusted, local contractor is going to be your best advocate when (not if) your unit has trouble. Ask Roberson Air Conditioning what we do differently.
What makes you better than your competition?
Roberson Air Conditioning prides ourselves in Customer Service, Thoroughness, and Innovation. We are committed to be the best trained, most technologically advanced, and highest rated HVAC company in Wharton County. But don’t take our word, look Roberson Air Conditioning up on your favorite review site or ask a Wharton local.
What is the warranty like on a new HVAC system?
Residential manufacturer warranties vary by equipment . Most units start with 10 year parts & 10 year compressor manufacturer warranty while Roberson Air Conditioning offers a 1 year in-house labor warranty on all newly installed HVAC systems. In most cases, manufacturer warranties only cover parts due to manufacturing defects. Non-manufacturer defects, maintenance, labor, materials, and refrigerant are the customer responsibility. Additional coverages can be added. Contact Roberson Air Conditioning for more information on warranty coverage and exclusions.
Is a Mini Split Right for me?
Mini Splits, also known as Ductless or Hybrid Heat Pumps, are a great way to cool or heat a small space or an entire home. The mini split products are built to be efficient, modular, unobtrusive, quiet, and customizable. They come in a wide range of sizes, styles, and applications. Contact Roberson Air Conditioning to see if they are right for your space.
How much does a new unit cost?
Unlike consumer electronics and appliances that can be easily compared online, delivered to your home, and simply plugged into your wall, HVAC requires a skilled craftsman to design, install, and commission a heating and cooling system to ensure it is correct for your home or business. Each application is unique and can range dramatically based on many factors like size, efficiency, market availability, enhancements, heating type, materials, ductwork, accessories, warranty, etc. Please contact Roberson Air Conditioning to get your free, specialized solutions.
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.
How do I know if my air quality is bad?
Bad indoor air quality (IAQ) can be noticed by allergic reactions, stuffy home, hot and cold spots, increased dust, muggy feeling, and more.

How do I fix the air quality in my home?
Poor air quality can be addressed with filtration, ultraviolet treatment, ventilation, humidity control, and temperature control. Ask Roberson Air Conditioning for a consultation to understand the state of your home's air quality.
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. Ask Roberson Air Conditioning how we can diagnose common odors and smells.
Can my HVAC system help my allergies?
Yes, your air conditioner and heater can help filter and remove allergens in the home. Using HVAC filtration, ultraviolet treatment, ventilation, and humidity control can reduce dust, mold, mildew, dander, moisture, dust mites, pollen and other sources of common & seasonal allergies.
