Miami Air Conditioning Repair: Condenser Coil Issues

Monday, March 25th, 2013

As the temperature begins to rise in Miami, FL, homeowners everywhere are beginning to check their air conditioners to make sure they are in good operating condition before the real heat starts. One of the most common issues concerns the condenser coils, which are housed in the outdoor unit. The purpose of the condensing coil is to condense the high temperature refrigerant gas into a liquid. The condenser coils therefore get hot, and require an extractor fan to blow the hot air off the coils. For Miami air conditioning repair, call Air on Demand today!

Let’s take a look at a few condenser coil issues:

  • Damaged cooling fins. The fins attached to the coils are meant to provide additional heat dissipation. If they are located on the top or the side of your outdoor unit, then they may be subject to general wear and tear as well as damage. If these fins become damaged, they can hamper the heat dissipation process and cause the condenser coils to overheat. 
  • Dirt and debris. Dirt and debris can often have a negative impact on the condenser coil, as they do with any part of your air conditioning. While it’s imperative to keep all parts of your AC clean, a dirty condenser coil can create significant airflow problems, and can reduce the cooling effectiveness of your system.
  • Corrosion. Whether due to high moisture conditions or old age, your condenser coil can begin to corrode. When properly maintained and attended to, this problem does not often become major. But if it does, it can cause serious damage to your AC system.
  • Leaks. Refrigerant leaks can impact your entire system. Because your condenser coils are outdoors, they are especially prone to physical damage. Without adequate levels of refrigerant circulating through both the condenser coils and the evaporator coils, your AC system will simply not work effectively. You may also end up paying for more electrical energy to run the machine

Whatever air conditioning repair you may need, Air on Demand is here to help. Our team of certified experts can help you get your Miami air conditioning back up and running in no time. Call us today!

Miami Air Conditioning Guide: Simple Ways To Improve Air Conditioning Efficiency

Monday, March 18th, 2013

As it begins to heat up in Miami, you need to make sure that your air conditioner will run all summer long. But more than that, you also need to make sure that it’s running efficiently so that you’re not wasting energy and therefore not wasting money. Here at Air on Demand, we’re committed to informing our new and current clients about simple ways they can improve their air conditioning efficiency this cooling season. For more information, or to schedule an air conditioning maintenance in Miami, call us today!

Energy efficiency is not only about reducing costs in utility bills, but also about reducing the energy that each homeowner uses for cooling, which is especially high during the summer months. Here are some easy and simply ways to improve air conditioning efficiency:

  • Enroll in a maintenance plan. This is the best way not only to improve your efficiency, but also to extend the lifespan of your system, as well as improve your comfort. Annual tune-ups make your system run cleanly and efficiently by removing debris, lubricating parts, and performing comprehensive inspections. Members of our maintenance plan also enjoy repair discounts, priority service, and no overtime charges. It’s a cost-effective way to boost your AC efficiency.
  • Clean your air filter. Your air filter prevents pollutants and debris from entering into your indoor air, but when they become dirty or clogged, they can actually impede the passage of cool air. This can cause increased moisture in your system and in general causes your system to work that much harder. Cleaning or replacing your air filter is an important and simple step to maintaining indoor air quality and efficient performance.
  • Install a programmable thermostat. These are excellent ways to customize your indoor temperature to certain times of the day and days of the week. It also improves efficiency by permitting automatic and gradual shifts in temperature, as well as turning your cooling on and off automatically, depending on your work schedule.

These are some simple ways to improve air conditioning efficiency in your Miami home. For AC maintenance, call Air on Demand today.

Miami Air Conditioning Tip: Basic Components of Your AC System

Monday, March 11th, 2013

Now that the cooling season is upon us, many Miami homeowners are turning on their AC. But quite a few of them don’t know how their air conditioning system works, which can make it hard to tell if their system needs repair. While it’s up to us to ensure that your system operates at its full capacity, informing new and current clients about the basic components of your air conditioning system is also part of our job at Air on Demand.  The sooner you recognize a problem or lack of performance, the more opportunity our Miami air conditioning technicians have to fix that problem quickly. Lingering problems could turn into larger ones. When you need air conditioning repair, maintenance, or replacement, call Air on Demand.

All of the basic components work as part of a refrigeration cycle, not unlike the refrigerator that keeps your food cold. Here are a few of the most important components:

  • Refrigerant. Refrigerant is the chemical mixture that travels throughout the indoor and outdoor coil systems, passing through a condenser and an evaporator. When air passes over the coils, it is cooled and circulated throughout your home. While R-22 refrigerant is now being phased out for R-410A, which does not contain ozone-depleting chlorine.
  • Compressor. This motorized pump pressurizes refrigerant, which allows it to change into liquid and gas at certain points in the cooling cycle. It runs on electricity, and in a split system is typically housed in the outdoor unit along with the condenser.
  • Expansion valve. This device is located between your hot coils and cold coils, and it controls the rate of pressurized liquid refrigerant entering the evaporator.
  • Thermostat. The thermostat is the user interface of the cooling system. It allows you to create a set point, which is your desired system temperature. It communicates this to the air conditioning system itself and adjusts airflow accordingly.

Miami Air Conditioning Guide: What You Need to Know About Environmentally Friendly Air Conditioning Refrigerant

Monday, March 4th, 2013

An important part of how your air conditioner makes your home cool during the hot Florida summer is a chemical mixture known as refrigerant. As it gets circulated through your air conditioner’s coils, the refrigerant changes from a liquid to a gas inside the coils in order to cool the air as it passes over them.

Up until fairly recently, CFCs (chlorofluorocarbons) were used in most air conditioning systems. When it became widely understood that the use of CFCs had ozone-depleting side-effects, many manufacturers switched over to more environmentally friendly refrigerants. The US Environmental Protection Agency officially phased out the use of CFC-based refrigerant in 2010 for new systems.

Nowadays, R-410A is the most common environmentally friendly refrigerant on the market. Being ozone-friendly requires a refrigerant that doesn’t use chlorine. Aside from the impact on the environment, switching to an eco-friendly refrigerant also reduces the risks of toxic chemical exposure in the event your refrigerant leaks. There are many alternatives on the market. To learn more about whether you can make the switch to a new refrigerant or new system, talk to the Miami, FL air conditioning experts  at Air On Demand.

If your air conditioner needs frequent repair is getting older, it may be more cost-effective to replace your unit rather than repair its broken components. Speak to a pro at Air On Demand today to understand what your air conditioning replacement and installation options are. Upgrading to a new environmentally friendly unit may not only help you save the environment, it may also reduce the amount of energy you use to cool your home.
