Miami, FL Air Conditioning Repair: My AC is Blowing Warm Air

Monday, April 29th, 2013

A well-maintained air conditioner is critical to the comfort of a Miami, FL home. Although we love the sun down here, it’s encouraging to know that we can find some respite from the heat and humidity when we go home for the day. Unfortunately, like all mechanical systems, air conditioners are prone to wear and tear, especially considering how much use they endure in our area. One such problem occurs when we find that our AC begins to blow warm air. Fortunately, you can rely on the Miami, FL air conditioning repair expertise of Air on Demand to ensure that your AC works well. Call us today!

There are a few reasons why your AC may be blowing warm air:

  • Dirty condenser coil: Your condenser coil is responsible for dissipating the thermal energy from the hot gas refrigerant into the outside air, with the help of an exhaust fan. Over time, it can begin to accumulate dust and other debris, which can deter this dissipation process. Under severe conditions, this can actually disrupt the refrigerant cycle and cause the hot gas refrigerant (rather than cool liquid refrigerant) to pass into the evaporator coil; hence, the warm air blowing through your ductwork. 
  • Clogged air filter: The air filter is designed to prevent the accumulation of dust and other debris from damaging or disrupting the operation of your system components. However, if it becomes clogged, it can begin to impede airflow, causing problems in the air handler and evaporator coil. For example, if your evaporator coil freezes over, then it cannot adequately cool the air.
  • Low refrigerant: You may encounter warm air if your system has particularly low levels of refrigerant. The refrigerant is chemically designed to undergo radical changes of temperature and pressure in order to move the heat extracted from the indoor air of your home outside. However, its “charge” must be exactly right in order for the system to operate effectively and efficiently.

These are just a few of the possible reasons why your AC may be blowing warm air. Call Air on Demand for excellent Miami, FL air conditioning repair services!

Miami, FL Air Conditioning Repair: Signs of a Broken Thermostat

Monday, April 22nd, 2013

We rely on our air conditioning systems every day to supply cool air to our homes and businesses. Your air conditioning system is complicated, with many different components and mechanisms, all working in cooperation to provide consistent cooling for your home. The thermostat is one of the most vital components because is the only interface you have for communicating with your air conditioner; without it, your AC could not turn on and wouldn’t know what temperature adjustments to make. Because of its importance, it’s critical that you recognize the signs of a broken thermostat, so that you can have it fixed or replaced. When you need Miami air conditioning repair services, call the experts at Air on Demand today!

Let’s look at a few common signs that your thermostat is broken:

  • AC won’t turn on:  If your AC won’t turn on, the cause could be a broken thermostat. It could be an electrical or wireless connectivity problem, whereby the link between your thermostat and the air handler is broken. There are other possibilities, but it’s often a faulty thermostat.
  • Inadequate cooling: If you feel as though your AC used to cool your home much better than it does now, it could be linked to faulty thermostat. If you feel like your AC turns off before the temperature reaches your desired setpoint, then the thermostat may not be sensing the correct temperature, or may not be communicating with the blower fan properly.
  • AC won’t turn off: While it may seem like you never want your AC to turn off during the summer, it should not be running all the time. Once sufficient cool air has filled up the living space, then the thermostat should communicate that the desired temperature has been reached. 

We hope this brief guide helps you to identify a thermostat function. For Miami, FL air conditioning repair, call Air on Demand today!

How You Can Prevent the Need for Air Conditioning Repair in Miami

Monday, April 15th, 2013

As we begin the cooling season in Miami, FL, you may have concerns about the operation of your air conditioning system. After all, we use our air conditioning systems a lot down here, and when the heat and humidity outside becomes uncomfortable, we need our homes to provide crisp and cool air. For this reason, homeowners throughout the area are looking for ways to prevent the need for repair. In this post, we’d like to run you through several ways to prevent the need for air conditioning repair in Miami, FL. For more information, or to schedule a service, call the pros at Air on Demand today!

  • Enroll in a maintenance plan: There’s no substitute for professional care. A routine maintenance plan is the best way to prevent the need for air conditioning repair. When a tech visits your home to look at the AC system, he knows exactly what to look for, having worked on hundreds of similar units and having had the training to diagnose even uncommon problems. Professional inspection, cleaning, and tune-ups allow your system to run as it should, and this service may be necessary if your AC is still under warranty. In addition to such comprehensive care, the maintenance plan also gives you discounts on repairs and new equipment, priority service and no overtime charges.
  • Clean and replace your air filter: This is one of the simplest tasks every homeowner can and should do on a regular basis during the cooling season. Unfortunately, dirty and clogged air filters are common causes of air conditioning repair. When the airflow of your AC system is blocked, it cannot operate properly. Make sure you check your air filter about once a month this summer.
  • Keep your AC clean and clear of debris: Dirt and debris are the number one causes of air conditioning repair. By ensuring that the area surrounding your AC units (both indoor and outdoor) is free of debris, you are significantly reducing the risk of major repairs due to neglect.

Air Conditioning in Miami Question: Why Does My AC Keep Turning On and Off?

Monday, April 8th, 2013

Short cycling is the term for when your AC keeps turning on and off. It can be incredibly frustrating, produce inadequate amounts of cool air, and reduce energy efficiency. While it can be difficult to diagnose, there are some common reasons for short cycling. The most important thing to remember is that inspection, diagnosis, and repairs should be carried out by a certified professional, in order to ensure that you are satisfied with the work that has been done and that the problem is solved, not just temporarily patched up.  For air conditioning in Miami, including repair, installation, and maintenance, call Air on Demand today!

So, why does your AC keep turning on and off? Let’s review some possible culprits:

  • Electrical problem. Your AC requires a steady stream of electric current to operate smoothly. It needs to have adequate load and its electrical connections need to be free and clear of any potential damages. If there is a fault somewhere, your AC may turn on and off frequently. It can also occur if it constantly blows fuses and trips the circuit breaker.
  • Leaking refrigerant. Your AC depends upon a pressurized cycle of refrigerant, which circulates through a system of coils and valves, absorbing heat and dissipating it. If there is a leak somewhere within this cycle, it can quickly lead to short-cycling as well as inadequate cooling. Make sure that a professional handles any refrigerant level adjustments.
  • Frozen coils. If you have a clogged air filter, your evaporator coils can quickly become frosted over. When this happens, your AC may need to defrost, and therefore be subject to turning on and off. It’s important that your system remains free of any dust and debris at all times.
  • Inappropriately sized system. If your AC is too large for the volume of air in your household, then it may short cycle frequently. An inappropriately sized system can also lead to excessively cold air, lack of temperature adjustment, and decreased energy-efficiency.

If your AC constantly turns on and off during the cooling season, it can negatively affect your energy efficiency as well as reduce system life. For AC Repair in Miami, including repair, maintenance, and installation, call Air on Demand today!

Miami, FL Air Conditioning Repair: Signs of an Evaporator Coil Problem

Monday, April 1st, 2013

Modern air conditioners have come a long way in efficiency, design and durability. There has been a lot of innovation over the years that allows us to keep our homes cool more effectively and reliably than ever before. Even the best air conditioners from the most trusted manufacturers in the business, though, are still mechanical systems. Like all mechanical systems, your air conditioner might eventually experience some sort of operational problem. When this happens, the Miami, FL air conditioning repair professionals at Air on Demand can help. Contact us the moment that you suspect a problem with your air conditioning system. One common issue is a problem with your evaporator coil.

The evaporator coil in your air conditioning system absorbs heat, and that cooled air is then circulated throughout your home. Because of this integral function, a problem with your evaporator coil can lead to a number of different problems. If your evaporator coil is dirty then you can expect a general decline in the performance of your air conditioning system. This is not a serious problem, so long as it is addressed as soon as possible. The longer you force your air conditioning system to operate with a dirty evaporator coil, the greater the risk of more serious damage to your system.

It is also possible for your evaporator coil to freeze. There are a number of different causes of this problem. It can be due to a dirty coil or blocked return grills, among other causes. An indicator of this problem is a low refrigerant charge. Contact a professional Miami, FL air conditioning repair technician to have this issue resolved as soon as you suspect a problem. Again, the longer your air conditioner is forced to work in this condition, the more likely you are to incur further system damages.

To learn more about your evaporator coil or to have yours repaired, call Air on Demand today. Our air conditioning repair technicians are here to help you keep your home comfortable throughout the cooling season. We have the skills and training necessary to handle any air conditioning repair you may need.
