The most common cause of low airflow from your vents is a blocked or dirty AC filter. When your filters are dirty, or the return air grill is blocked, it decreases the efficiency of your entire AC system and significantly reduces its ability to cool your home. Be sure to keep the area around your AC filter clear and clean or change your AC filter once a month during heavy-use times like summer. Other causes of low airflow include bad blower motors, frozen coils, or ducts that have split open.
If you have ice on your air conditioner, the first thing you should do is shut the unit off to allow your system to thaw. Our AC Techs will not be able to diagnose your unit while it is blocked with ice. Next, check your AC filter and replace, if needed. If your filter’s not dirty, give our office a call at 512-450-1980 to schedule an AC diagnosis today. A dirty evaporated coil, low levels of refrigerant (R-22 or R-410A), restricted airflow through the AC unit, or other mechanical failures that need to be repaired by a licensed HVAC technician, could all be the cause of the ice on your unit.
If your thermostat is blank, that means there is no power going to the thermostat. First, replace the batteries on the back of the thermostat. If your thermostat’s display is still blank, check the power switch of your HVAC system located by the indoor furnace or AC unit which is usually located inside the mechanical closet or in the attic (if your indoor unit is located in the attic). The last thing that can be checked prior to calling our AC repair service is the breaker in your breaker panel, as well as the breaker located behind your outdoor unit. If you are still experiencing a blank thermostat after checking the above-mentioned items, give your AC repair company a call to schedule a diagnosis. If the issue is not related to equipment failure, you might have a clogged drain line that tripped your emergency float switch.
If your AC & Heater is not turning on, before calling your local AC Repair company check to make sure your thermostat is set to the correct mode, (i.e. Cooling or Heating). Then, check the power switch of your HVAC system located by the indoor furnace/ac (usually inside the mechanical closet, or in the attic if that’s where your indoor unit is). If this switch is flipped to “on”, check the breaker in your breaker panel, as well as the breaker located behind your outdoor unit. Lastly, check the batteries on your thermostat. If these mentioned steps do not solve the issue, call your trusted AC repair company to check out your AC or heating unit.
Under no circumstances should you ever see water around or inside your AC unit. As soon as you discover a leak, be sure to turn off your air conditioner and call for help right away. Turning off your AC can help prevent further damage to the electrical components of your AC and limit the amount of water damage to your home. A clogged drain line, a frozen coil, or a drain pan that has a hole inside the pan could cause the water leak. Remember that an HVAC unit that receives regular twice-annual maintenance is likely to need costly repairs.
A good rule of thumb is to replace your standard 1-inch AC filter every 30 – 90 days depending on usage of the AC system, number of occupants in the house and environmental conditions. If you have pets or suffer from allergies, consider replacing your AC filter more often. If your HVAC system uses a thicker 4-inch filter, these should be replaced twice a year. At A-Plus, if any homeowner has a replacement filter at the time of an AC tune-up or repair service call, our techs will replace your filter at no additional labor cost.
To make a long answer short, you should opt to use the cheapest, PLEATED filter available in the correct size for your unit. Avoid all fiberglass air filters as they do not filter most dust, allergens and particles. They can also cause damage to your AC coil.
The longer your AC runs the more humidity it removes from your home. If your AC unit is short cycling or not running long enough, your home may feel more humid. If your AC system is low on refrigerant (Freon) or is oversized, that could cause excess humidity as well. A dehumidifier may help alleviate the situation. If your AC unit is over 10 years old, replacing your HVAC unit should be considered.
If one room is colder or hotter than the rest of the house, you should have an evaluation of your ductwork to see if the ducts need to be replaced or modified to correct the airflow imbalance. An Energy audit is an evaluation of your ducts, as well as other weatherization improvements that help make your home more energy efficient. Installing dampers and proper air balancing of your ducts can help remedy the situation.
An Energy Conservation Audit and Disclosure (ECAD) is required for homeowners selling homes more than 10 years old within the Austin Energy service area, located within the Austin city limits, unless the homes have completed the Austin Energy Whole House Rebate program within the last 10 years. If you are unsure if you home needs an ECAD audit, you can speak to an ECAD auditor at (512) 450-1980 for confirmation.
The seller of a residential building is required to pay for and provide the ECAD audit to the buyer prior to the sale of their home. Non-compliance with the ECAD ordinance can result in fines up to $2,000.
A Certified ECAD Energy Professional will fill out a report auditing the homes AC and heating systems’ efficiency, duct performance, attic insulation levels and other energy efficiency measures. For more information about what is included, check out the Austin Energy ECAD website.
An Energy Conservation Audit and Disclosure (ECAD) is an audit required by Austin Energy for homes that are being sold in Austin.
