AC Blowing Warm Air | AC Repair

Air Conditioning Repair | AC Blowing Warm Air

The air conditioning remains in use during overly warm fall days. When the AC breaks down during what may well be the last warm days of fall don’t panic. The cause may a simple one that you can correct yourself. You had planned to have a new unit installed next spring, and are reluctant to pay for air conditioning repair. After all, the money could go towards a new system. Try the following tips before calling for repair:

When the AC is blowing warm air, check out the following before calling for repair:

  • First, check the fan setting. If the fan is sitting in the ON or RUN position rather than AUTO, the fan will run continuously, blowing warm air unless the compressor kicks on.
  • Check the thermostat and ensure it is in the COOL position. Next, check the temperature of the room and the selected temperature. The selected temperature must be lower than the inside temperature reading for the AC to cut on. If the thermostat says the inside temperature is 84 degrees F; the air conditioner will not cut on with the thermostat set at 85 degrees or above.
  • Check to ensure all air registers are open. Do not block registers or the air return. Ensure the area around them remains clear to allow proper air flow.
  • Check the filter, a dirty filter can prevent airflow to the system, reducing its efficiency and can lead to overheating of the system and cause a breaker to be thrown. It can also cause dirty coils which can lead to a lack of cooling. On average, filters should be changed monthly unless otherwise specified by the manufacturer.
  • Check the home electrical service panel; all circuit breakers should be in the ON position. If the AC breaker is off, flip the switch back to ON and check for AC operation.
  • The condenser is the portion of the system located outside of the home. There should be a disconnect switch located near the unit in a box mounted nearby on the house. Ensure it is in the ON position. Listen for the fan running on the central unit. If ice is visible you will require air conditioning repair. For proper operation and to prevent potential damage, the condenser should not be blocked by vegetation or other objects.
  • Split systems may have a breaker located inside the units air handler within the home. If applicable to the HVAC system in your home, ensure it’s in the ON position. Be cautious of wiring due to the risk of electrical shock. If ice is present on the refrigerant lines you will require a certified HVAC technician for repair.
  • Tripped electrical breakers can be a cause of the AC blowing warm air. The loss of refrigerant is also potential cause of the AC blowing warm air.

Once you have provided these steps, if the AC is blowing warm air, it will require repair by a certified technician. Routine annual maintenance of the AC system, or bi-annual maintenance for heating and air conditioning systems during the spring and the fall, along with routine filter changes is the most effective action a homeowner can provide in preventing breakdowns.

When replacement seems to be your best option, Garland Heating and Air Conditioning can assist you with financing available through Wells Fargo Financial.

Air Conditioning Filters | Dallas, TX

Air Filters | Air Conditioning, Dallas, TX

You depend upon your home’s heating and air conditioning in Dallas, TX to provide year-round comfort. The air filters purpose is to protect the system from dust and dirt, which creates wear from friction when a dirty filter allows it to enter the system. The wear and tear will shorten the service life of your HVAC system, and will negatively impact its efficiency and performance. Changing the air filter on a routine basis will help to ensure the longevity of the system, and maintain your comfort and indoor air quality.

Using the appropriate filter for your heating and air conditioning system is important to receive the best performance. Filters are not all created equal, and an improved filter quality isn’t always the best thing for your specific system. There are various grades of air filters, and some work better than others. However, a superior filter may be denser than your system can draw air through. If this occurs, your system may be damaged due to the strain placed upon it in its efforts to draw air. If you are uncertain of the appropriate filter to use in your heating and air conditioning in Dallas, TX, contact the manufacturer or give us a call.

Once the dust and debris have accumulated to a certain point the filter becomes ineffective, and can even block airflow, and allow damaging dust to enter into the HVAC system and your home. The best way to prevent a failed air filter, ensure cleaner air, and enhance the HVAC system’s longevity is to routinely change the air filter for your air conditioning in Dallas, TX.

How often the filter should be changed will depend upon the amount of dust and debris that collects, and the type of filter it is. The air filter should be checked every month. Choose a day, such as the 1st for example, for filter check day. Many filters require changing every month, such as the cheap blue filters. Others are good for 90 days depending upon certain conditions that may apply. If any of the following affect your household more frequent changes may be required:

  • A family member with allergies or asthma.
  • Pets in the household.
  • The use of a fireplace or a wood heater.
  • The presence of a lot of dust and/or pollen.
  • Being located on an active farm where activities stir up excessive dust.
  • Having a smoker in the home.

If any of these conditions are relevant to your household, check the filter every 2 weeks and change as required but no less than once per month for the best performance of your air conditioning in Dallas, TX.

Utilize the following tips for improving performance:

  • Ensure the filter is inserted correctly. There should be an arrow indicating which way the filter should be located in the air return for appropriate filtration.
  • Do not clean disposable filters, dispose of them once they are soiled, or if they become wet. A wet filter in the air return without explanation may indicate a problem. Contact your Garland Heating and Air Conditioning certified technician for repair to the air conditioning in Dallas, TX.Only permanent filters can be cleaned and remain effective and efficient. Do not risk mold forming within the system by reinserting a wet or damp permanent filter, let reusable filters dry completely before reinserting it.

Furnace & Air Conditioning Tune-up

Furnace Tune-Up in Dallas | Air Conditioning Service

Providing the annual heating and air conditioning service to your home’s HVAC system system is one of the two most important actions a homeowner can take to ensure the longest service life possible of the system. Now that fall has arrived, and winter approaches, it is time to schedule an inspection and furnace tune-up in Dallas.

You may think because the HVAC system was tuned-up last fall that it should be fine for this year. However, tune-ups are not the only reason for annual heating and air conditioning service. For example, a gas furnace can develop deposits due to combustion that not only reduce the performance and efficiency, but can cause dangerous levels of carbon monoxide gas to accumulate in your home. In other words, the system needs to be cleaned and inspected to ensure safe and efficient operation each year.

There are numerous benefits and reasons for annual heating and air conditioning service with inspection and tune-up. Let’s have a look at them:

  1. The inspection can identify components that are weakening or not functioning as they should. If not addressed with repair or replacement, they can leave your family without heat during the cold winter.
  2. Inspection will identify if the burner has developed dangerous holes, cracks or if it requires cleaning. These conditions single or together can present life threatening, health and safety issues.
  3. Inspection can identify an electrical problem or a fan motor in need of lubrication to prevent it from locking up, or even starting a fire.
  4. The flues are how a gas operated furnace ventilates deadly carbon monoxide to the outside of the home. A partially clogged flue can place your family at risk. An inspection will identify if the flue needs to be cleaned.
  5. Properly maintained HVAC equipment will last longer, and by identifying problems early, can prevent more costly repairs from developing.
  6. Equipment that receives annual heating and air conditioning service runs more efficiently, saving you money on the cost of operation, while maintaining comfort.
  7. Numerous manufacturers require routine maintenance to maintain the factory warranty.

Furnace Issues and Warning Signs

While a furnace won’t always give warning signs of impending problems, there are some signs to be aware of:

  1. A pure blue flame is a normal ignition flame in a gas furnace. If the flame appears yellow, orange or red, contact your HVAC provider. The pure blue color indicates know the furnace is receiving the correct mixture of oxygen and gas. Prompt attention is required if the flame is not blue.
  2. Unusual odors and sounds are a warning of the need for repair or replacement in gas or electrical furnaces. Some odor is expected when a furnace has been unused over the summer months due to the collection of dust on the burner. Dust should burn off fairly quickly. Examples of unusual odors to be aware of are burning wire or insulation smells and burning oil smells. If you detect unusual odors, shut the furnace off immediately and call your HVAC technician for heating and air conditioning service.
  3. An aging furnace is more vulnerable to frequent breakdown and complete failure. Routine maintenance can help to extend the service life of a furnace, but eventually the furnace will fail and require replacement. When keeping an old furnace going requires frequent repair, you would do better to consider investing the continued repair costs into a new and reliable furnace.
  4. Thermostats will also eventually become worn and fail. Signs of thermostat issues are a system that runs too often, or too little and failing to maintain a consistent temperature in your home.

The second most important action a homeowner can provide to their homes heating and air conditioning is to inspect and/or clean or change the filter monthly. Not all filters will require a monthly change, but filters should be checked each month to ensure proper operation and efficiency. Proper care or change will depend upon the type of filter used.

Our certified and experienced HVAC technicians will provide the inspection and furnace tune-up in Dallas that you need, to ensure the safe and efficient operation of your home’s furnace.
