Can I Keep Running My Air Conditioner with Low Refrigerant?

Friday, September 19th, 2014

Without any refrigerant at all, your air conditioning system would be incapable of cooling your home. But if you have low levels, you may still be able to feel some cool air from your system. Air conditioners need refrigerant to remove heat from the air, but can you still run your unit with low refrigerant?

You should not attempt to continue running an air conditioner with low levels of refrigerant because many of the parts of your air conditioner require a set level of this chemical blend in order to work properly. When an air conditioner is installed, a technician is supposed to carefully measure out the correct levels of refrigerant. If these levels are not accurate, it may be because your unit was not set up properly in the first place. However, it’s also likely that this is the result of a leak.

Refrigerant may leak from your system due to loose connections or corrosion over time. If it continues to leak from your unit, you may not feel any cool air at all. But even slightly lower levels may cause problems with some key components like the compressor. The compressor is responsible for changing refrigerant into a pressurized gas so that it can pump through the entire system. This part is sized to handle a certain load of refrigerant based on the cooling capacity of your air conditioning unit. When this amount drops too low, your compressor will run into problems that may even lead to replacement.

In fact, many parts of your unit may suffer from wear and tear when refrigerant is low. And when the parts in your system have to work harder to cool your home, your unit will use a lot of energy to reach the desired temperature. This means you spend a lot more every month than you need to, and your air conditioner may already consume a large portion of your bills. To keep bills low, and to keep your unit from suddenly failing, schedule maintenance twice a year and make repairs as soon as you suspect a leak.

When Is It Time to Replace a Heat Pump?

Friday, September 12th, 2014

Your heat pump is an important device: it supplies both cooling and heating to your home. While we may still be in the cooling season here in Florida, the time is quickly coming when the weather will cool and we’ll need your heater. If you have a heat pump, switching modes between heating and cooling is very easy due to the reversing valve: all that is involved is a simple switch from cooling to heating on your thermostat. It can be hard to distinguish the signs of a failing heat pump, so below are some of the common ones our Downtown Air & Heat technicians see fairly frequently:

Signs It May Be Time to Replace

  • Excessive noise – one of the benefits of heat pumps is they are quiet compared with other devices. If you start to hear loud noises every time your heat pump runs, this can be a possible indication of major mechanical problems.
  • Age – the average lifespan of a well-maintained heat pump can be pretty long – about 20-25 years. If you are coming up on the 20 year mark, and have had to make a number of repairs to your heat pump, you may be better off putting your money toward a new one.
  • Poor temperature control – heat pumps are known for their even heating and cooling because they cycle at a consistent, low rate. If you are experiencing temperatures that are too hot or cold, it may be a sign that your heat pump is ready to go.

Heat pumps are great 2-in-1 devices, but the flipside of this benefit is that a poorly-working heat pump will affect both your cooling and heating. Being without air conditioning in Orlando, FL is a challenge, and no one wants to be without heating on a cool winter day. And because heat pumps are complex, it’s important to hire a professional for installation. If it’s time for a heat pump replacement, let the NATE-certified technicians at Downtown Air & Heat help you with your air conditioning service in Orlando, FL – call us today!

Why Consider Duct Sanitizing?

Friday, September 5th, 2014

Bacteria, mold, mildew and other biological growths can thrive in ductwork due to its cool, dark, moist environment. While a professional duct cleaning can remove mold and mildew, it doesn’t guarantee that there won’t be another occurrence of growth, nor does it eradicate the biological contamination. To truly remove biological contamination, and to protect against further growth, you may want to consider duct sanitizing for your air conditioning system.

What Is Duct Sanitizing?

Duct sanitizing is a multi-step process in which an EPA-approved chemical sanitizer(s) is thoroughly applied to the inside of your ductwork to eliminate germs and biological growth, and prevent the development of new growth. Each vent is treated individually, and the application of the sanitizer usually needs 10-15 minutes to cure.

What Types of Sanitizers Are Used?

There are 3 main types of sanitizers that can be used on your ductwork:

  • EnviroCon – EnviroCon is used to eliminate odor-causing microorganisms and contaminants such as mold and mildew; it can also treat bacterial growth. EnviroCon eliminates odors via a chlorine dioxide release-process that destroys organisms at the cell level. EnviroCon has low toxicity and a good safety rating from the EPA.
  • Microban – Microban is used to eliminate most fungi, bacteria and viruses. Microban kills allergy and disease-causing germs, odors, and growth like mold and mildew. Microban is only available through professional cleaners and restorers. It is labeled as safe by the EPA.
  • F.P. sanitizers – F.P. sanitizers are concentrated liquid sanitizers used for sanitizing pre-cleaned surfaces in air ducts and air conditioning systems. They contain surfactants (compounds that act like detergents) that give them additional cleaning power. These types of sanitizers are labeled as safe by the EPA.

Benefits of Duct Sanitizing

  • Healthier air – your ductwork is the delivery system for all the air in your home; if it’s clean, you air will be, too.
  • Keeps ductwork clean – sanitizers have a lasting effect, so they help keep your ductwork free of contamination after application.
  • Reduction of allergens – allergy-inducing particles are eradicated during sanitizing, helping to reduce allergic reactions to the air in your home.

If healthy indoor air is a priority for your home, you might want to consider scheduling professional duct sanitizing for your air conditioning. Have questions? Call Downtown Heat & Air today and speak with one of our Orlando, FL air conditioning service professionals.

3 Benefits of Replacing an Air Conditioner

Friday, August 15th, 2014

If you have an older air conditioner, the decision to schedule air conditioning replacement may be tough. Of course, you don’t want to spend money replacing a system that may last another couple of years. On the other hand, there is always the risk that your older unit may break down, costing you more money to fix and inconveniencing your home. Older air conditioners are far more likely to break down suddenly than new systems. They may not perform as well as they once did and often are inefficient. If you’re currently deciding whether or not air conditioning replacement is a good idea, here are three reasons to call a technician today.

Prevent a Costly Breakdown

If you have an older system, the chances of a sudden breakdown occurring may be high. Throughout the years, your system gets a lot of use, so wear and tear on the system is to be expected over time. While repairs and parts replacement may help fix a problem from time to time, the only way to improve the working condition of your air conditioner entirely is by purchasing a new system. Replacing a system piece-by-piece is costly, and new air conditioners are a lot less likely to need repairs than those that are 10-15 years old.

Energy-Efficiency

One important reason to install a new air conditioner is the energy savings. Your air conditioner may remain efficient for many years with proper care and maintenance. However, the efficiency of your system will start to decrease eventually, and your bills will reflect this. Newer systems are far more efficient than older systems. In fact, due to government requirements for efficiency, a new AC may have a higher SEER (Seasonal Energy Efficiency Ratio) than your older system had, even when it was brand new.

Better Performance

Energy-efficient systems are not lacking in performance. High-efficiency air conditioners perform just as well, if not better, than other systems. Look for a system with the ENERGY STAR label. This label ensures that a system has met government requirements for both efficiency and performance.

You should always discuss your decision with an air conditioning technician before coming to a decision. Call the experts at Downtown Air & Heat today to schedule air conditioning replacement service in Orlando.

What Is a High Efficiency Air Conditioner?

Thursday, July 31st, 2014

Today’s air conditioners are very energy efficient. In fact, estimates put today’s air conditioners up to 60% more efficient than models produced just 10 years ago. Energy efficiency is important for you, your home, your family, your air conditioner and the environment. As technological advances continue to present more efficient cooling products, the greater the opportunity you have to purchase an AC that fits both your cooling and energy needs. If energy efficiency is at the top of your list of needs when it comes to purchasing a new air conditioning system in Orlando, you may want to look at what a high-efficiency system can offer you.

What Is a High Efficiency System?

A high-efficiency air conditioner is an AC with a SEER of 16 to 23. A high-efficiency air conditioner allows you to cool your home using less energy than an air conditioner with a SEER below 16.

Why Consider Using a High-Efficiency AC?

There are several reasons you may want to look at purchasing a high-efficiency air conditioner for your home:

  • Significant energy efficiency – as mentioned above, one of the main attractions of purchasing a high-efficiency air conditioner is how little energy it uses to cool your home.
  • Lower monthly energy bills – when you use less energy, you pay for less energy. It is estimated that each SEER point can mean up to a 10% savings on your energy bill, so the difference between a SEER of 13 and a SEER of 16 can mean a lot to your household budget.
  • More eco-friendly – obviously, using less energy is eco-friendly; additionally, high-efficiency systems are manufactured to use the more Earth-friendly coolant R-410A instead of R-22.

Is a High Efficiency System More Expensive to Purchase?

The answer: yes, it can be. A higher SEER number can often mean that the initial purchase price is higher than those air conditioners with a lower SEER. However, the amount of money you’ll save each month in energy costs can offset the price point.

A high-efficiency air conditioner can be a great choice for cooling your home, but the best way to assess this is to work with an installation expert. Call Downtown Air & Heating today and schedule an appointment with one of our professionals to see if a high-efficiency air conditioner is a good choice for your new air conditioning system in Orlando.

Is a Ductless System the Right Choice for Me?

Friday, July 25th, 2014

There are two basic types of air conditioning systems that deliver air into your home: ductless or ducted. The majority of homes in the U.S. have pre-existing air ducts hidden in the walls to provide cool air. However, some older homes do not have any ducts installed, or a new room addition may require homeowners to find a ductless solution. Ductless air conditioners use indoor air handlers to provide cool air or heat to a home, and can help homeowners save money every month on their energy bills.

But is a ductless system the right choice for you?

Benefits of a Ductless System

  • No Ductwork Installation: The most obvious benefit of a ductless system is the lack of ducts. This is ideal for homes in which ductwork installation would be difficult or impossible due to the unique structure of the home.
  • Zone Control: With a ductless system, you get to choose the temperature in the different rooms or areas throughout your house. You will no longer have to listen to family members bicker over the thermostat; instead, each air handler usually has its own thermostat, or you can control every unit at once with a master thermostat.
  • Energy Savings: Ductless systems often have much higher SEERs (Seasonal Energy Efficiency Ratios) than ducted systems. Plus, zone control allows you to save money by turning on the air conditioner only in areas of the home that are occupied throughout the day.
  • Cost of Ownership: The initial cost of a ductless system is often higher than the cost of central AC. However, the energy savings every month will likely make up for this over time.
  • The Appearance of Air Handlers in the Rooms: Some people may be put off by the air handlers, but they are generally placed out of the way, either suspended from the ceiling or mounted high on the wall.

Drawbacks of a Ductless System

Ductless air conditioning is not right for every home, and you should talk with a technician before coming to a decision. For specialized air conditioning services in Orlando, call Downtown Air & Heat today!

Signs that You Need Air Conditioning Repair

Friday, July 18th, 2014

If you’re a busy homeowner in Orlando, it can be hard to find time to schedule air conditioning repair service. But in the middle of summer, a sudden breakdown would probably be much more of an inconvenience.

If you notice any of the following signs, make the time to call an air conditioning technician today to avoid problems later on.

  • Loud Noises: You expect to hear the whir of the outside fan, but if your air conditioner begins to make unexpected noises such as a banging, hissing, or grinding noise, you should shut off your AC and call an expert for repairs immediately to avoid any damage to your system.
  • Short Cycling: If your air conditioning system stops running before your home has reached the desired temperature, there may be any number of problems causing your air conditioner to short cycle. Short cycling can be caused by a refrigerant leak, ice on the coil, compressor damage, or an AC system that is oversized. Because of the large number of possibilities, you should always allow a professional to determine the correct source.
  • High Utility Bills: If your energy bills have been higher than usual recently, it may indicate a problem with your air conditioner. Over time, an air conditioner will lose some efficiency, but a dramatic increase should be cause for alarm. High energy bills can mean that a component of your air conditioner is dirty. You can try cleaning your air filters, but it may also indicate a dirty coil or leaky ductwork.
  • Loss of Cooling Capacity: If you notice that your air conditioner has lost some cooling power, it can be due to any number of issues. Your air conditioner may be low on refrigerant, you may have a dirty or frozen coil, or the thermostat may be faulty.

Anytime you notice something unusual with your AC system, contact Downtown Air & Heat for air conditioning repair in Orlando. Our experts are trained to identify the problem and help you determine the best course of action. If you need air conditioning repair, call us today!

How to Help Your Air Conditioner Perform at its Best

Tuesday, July 8th, 2014

All air conditioners experience some wear and tear over time that will eventually cause decreased performance. But that doesn’t mean you can’t slow down this process. These simple steps may improve the performance of your air conditioning system and keep it running smoothly for years to come.

Change or Replace air Filters

One way to help your air conditioner continue to perform at its best all summer long is changing or replacing air filters regularly. Clogged air filters obstruct airflow, which can cause a lot of further issues, such as a frozen evaporator coil. Debris buildup in your ducts caused by blocked filters may also cause decreased efficiency and performance. You should change or clean air filters about once a month, following the manufacturer’s guidelines.

Schedule Regular Maintenance

Another way to keep your air conditioner in top shape is by scheduling regular maintenance. Even if your air conditioning system doesn’t seem to need repairs, you may want to have a technician look at your system during a routine maintenance visit. People who schedule maintenance once a year often have increased performance and decreased energy bills every month.

During maintenance, a technician will inspect your system, clean some of the parts, adjust refrigerant levels, and add lubricant to the motors, if necessary. A technician can let you know if any part of your AC is affecting performance and needs repair.

Upgrade to a Digital Thermostat

Another reason you may choose to call an air conditioning professional is if you are using an outdated thermostat. If you still set the temperature in your home with the dials of a manual thermostat, you may not quite get the cooling power you hope for. In this case, you can benefit from a digital, programmable thermostat with a clear display that allows you to set the AC to turn on and off at different times of the day. You may end up using your AC less often, resulting in less wear and, possibly, a longer lifespan for your system.

How Does Humidity Affect AC Performance?

Thursday, June 26th, 2014

The comfortable range for humidity is 30%-60%; the average humidity levels in Orlando between June and August range from 61%-92%. Clearly, our air conditioners are a necessity.

Not only do our air conditioners cool us, they help remove the humidity, which is a big part of our heat here. Even though your AC system is designed to remove humidity as part of regular operation, there are times when the moisture can be excessive for your air conditioning and potentially affect its performance. This is when you want to call Downtown Air & Heat.

How Does Humidity Affect My AC?

There are several ways in which humidity can adversely affect your air conditioner:

  • More stress on your system – when there is excess moisture in the air, not only does your air conditioner have more moisture to remove, it also has more heat to fight. More humidity means your air conditioner has to work harder to cool the same way as when there’s less humidity. This can put more stress on your system, particularly if it hasn’t been properly maintained.
  • More problems for allergy sufferers – not only does pollen like to cling to humidity, too much moisture is one of the reasons dust mites, mildew, and mold flourish. By properly dehumidifying the air, you can help prevent allergens from hanging in your indoor air and developing in your home.
  • Less comfort indoors – the point of having an air conditioner is to feel comfortable during the hot months of the year. When too much humidity is present, it can make the cool air in your house feel cold and clammy. This kind of discomfort can be as uncomfortable as experiencing the heat, something no one wants from their AC.

The Best Way to Handle Humidity

One of the best tools available for handling the extra humidity that comes with the Orlando heat is a whole-home dehumidifier. Whole-home dehumidifiers help remove the extra humidity in the air, giving your air conditioner the breathing room to operate optimally, even during long periods of excessive warmth. Let Downtown Air & Heat help you lift the weight of the humidity this summer with a whole-home dehumidifier for your air conditioning system. Call us today and schedule air conditioning service in Orlando with one of our experts.

Avoiding the Need For Air Conditioning Repairs

Thursday, June 19th, 2014

The last thing anyone wants to deal with during a hot summer in Orlando is an air conditioning repair. Over the years, our Downtown Air & Heating customers have asked our experts if there are ways to help prevent repair needs from developing, and the answer is yes, there are ways to help curb the need for air conditioning repair to your system. Some repairs are not avoidable, but by taking certain steps we’ll outline below, you can decrease both the need for repairs and the size of the repairs to your air conditioning system.

Don’t Ignore Signs of Problems

Strange sounds, unfamiliar smells and a subpar performance can all point to problems that developing with your air conditioner – don’t ignore them. While your air conditioner may still be running, it may not be running well, and there is a limited amount of time your AC can run under stressful conditions. As the saying goes, it’s better to be safe than sorry, so if something seems even a little bit off, call your Downtown Air & Heat technician to take a look.

Change/Clean Filters Regularly

Your air filter can become clogged with dust and dirt. When the filter becomes too clogged it can restrict airflow, which can lead to multiple problems with your system. By changing the air filter every 1-3 months, you can avoid the problems that develop from a dirty air filter.

Schedule Regular Maintenance

Regular maintenance is one of the best ways to stave off repairs and keep your air conditioner running optimally. With bi-annual maintenance, your system is thoroughly inspected for any issues, cleaned, and adjusted and/or repaired as needed. Scheduling bi-annual maintenance means the small things, like worn fan belts and loose screws, are taken care of before they can lead to bigger, and potentially more expensive, repairs.

Keep the Outdoor Unit Clear

While a specialist should clean the interior components of your outdoor unit, you can help with maintenance by cleaning up any yard debris from the area around the outdoor unit, and making sure there is no overgrowth from trees or shrubs encroaching on the space.

Think You May Have an Issue?

Even if you aren’t sure if something is going on, it’s better to get ahead of your repairs than to wait and see. Get ahead of any potential issues – give Downtown Air & Heating a call and schedule air conditioning repair in Orlando today.
