3 Benefits of Ductless Mini Split Air Conditioners

August 20th, 2014

Ductless air conditioning as an option for home comfort has taken off during the last two decades. Originally, ductless mini splits were used primarily for businesses (they are especially popular for restaurants) but their numerous benefits have made them impossible for homeowners to pass up.

If your home is right for installation of a ductless mini split AC, you should give the idea serious consideration. We’ll look at some of the advantages you can enjoy when your go ductless for cooling down your home.

Air on Demand installs ductless mini split air conditioners in Miami, FL. This is a complex job, and isn’t something you want to delegate to inexperienced amateurs (or attempt to do yourself) so contact our team when you think that ductless is your best choice.

3 of the Benefits of Ductless ACs

  • They also provide heat: Ductless air conditioners are actually ductless mini split heat pumps. That means they can provide heating as well as cooling. Heat pumps are excellent for Florida weather, since they work as well as any standalone air conditioner of comparable size and can ably handle our mild winters while in heating mode.
  • They help protect indoor air quality: One of the unfortunate problems with ductwork is that it collects dust, dirt, dander, and other contaminating particles, which is then blown out into your home’s air and recirculated. Only regular duct cleaning can prevent this. When you eliminate ducts with the installation of a ductless mini split, you take away this reservoir for pollutants and help keep your air healthier without the need for regular cleaning. If you have people with allergies or asthma living in your home, going ductless can make their lives much easier.
  • Energy savings: Ductless mini split heat pumps send conditioned air into your home through wall-mounted blower units, each which connects to the outside unit. Because you can individually control the blowers, you only have to send conditioned air to the parts of the house that need it. Unlike a central AC, you don’t have to cool down the entire house each time the system comes on, and this will lead to a reduction in your utility bills. You will also reduce the energy loss that can happen along the length of ductwork, increasing your savings.

Ductless mini splits are not right for every home: they work best for new construction, remodeling, add-on rooms, or for older and historic homes that lack the room for ducts. If you are unsure about installation, call the professionals at Air on Demand. We can look over your home and your current AC and determine if installing one of our ductless mini split air conditioners in Miami, FL is your best option for year-round comfort.

How Do Commercial HVAC Systems Differ from Residential Systems?

August 13th, 2014

Would you mow several acres of lawn with a push mower, or use a motorcycle for a family of 5? These are strong examples, but they demonstrate one of the key ways residential HVAC systems are different from commercial ones: size. While there are common, fundamental mechanics between commercial and residential systems, the systems are not the same. Working with professionals who have the knowledge and experience needed for commercial HVAC service is important for both you and your business. For over 30 years, Air on Demand has been providing commercial HVAC services in Pinecrest, and our trained technicians are available for any commercial repair you may need.

What Are the Differences?

As we stated above, one of the biggest differences between commercial and residential HVAC systems is their size. But there are others that are also important:

  • Many are packaged units – because commercial HVAC systems have to cover a great deal more square footage than the average household, they are often manufactured as one large unit called a packaged unit. These units are called packaged because all the components – the compressor, condenser and evaporator – are all housed in a single cabinet. This makes repair work easier because the components are more accessible.
  • Complex drainage – a commercial HVAC system covers large spaces; as such, the drainage system is far more complex than the simple condensate tray and drain you’ll find in a residential property.
  • Use of modular units – over the last few years, modular units have become very popular in the commercial HVAC industry due to their flexible nature. As businesses move in and out of spaces, cooling needs can vary; with a modular system, these needs can be met without having to re-design the cooling for that space. If less cooling is needed, one of the modular units can be removed; if more is needed, a modular unit can be added.

Having the proper amount of cooling is vital to your business. Do you really want to trust it to a company that doesn’t specialize in commercial HVAC services in Pinecrest? If you have been experiencing problems with your commercial HVAC system, call the professionals you can count on: Air on Demand.

What the ENERGY STAR Means for Your Air Conditioning

August 6th, 2014

While cost is an important consideration for most homeowners when shopping for a new air conditioner, the price tag should not be your sole consideration when searching for a system that will save you money. Air conditioning accounts for a large portion of energy bills in the summer, so you should look for an energy-efficient system that will save money over time.

The U.S. government requires all air conditioning manufacturers to provide information about the efficiency of the unit. The rating system used to identify this is known as SEER (Seasonal Energy Efficiency Ratio). The SEER is calculated by determining the cooling capacity of an air conditioner in a standard cooling season and dividing this number by its total energy consumption. While the government only requires air conditioners to have a SEER of 13 or higher in order to be sold in the U.S., systems must have a SEER of 14 or greater to earn the approval of the Environmental Protection Agency.

The EPA has established a set of guidelines that air conditioners must meet to earn the ENERGY STAR. While a high SEER is an important consideration when purchasing a new air conditioner, you should also pay attention to whether or not your new system has received this distinguished symbol. ENERGY STAR systems meet strict guidelines of both performance and efficiency and release fewer pollutants into the air than conventional models.

While the ENERGY STAR label can help you determine energy efficiency, a high number alone will not save you money year after year. First, the system must be installed properly so that it doesn’t run into problems early on. Second, proper maintenance is necessary to ensure that your system remains efficient throughout its life. Be sure to clean or replace air filters about once a month and schedule maintenance every year. Scheduling maintenance with an AC technician helps restore some efficiency and improve performance.

An AC technician can help you find a system with the ENERGY STAR label, calculate the proper size, and professionally install the unit. For professional air conditioning service in South Dade, pick up the phone and call Air on Demand today to speak with a qualified technician about your AC needs.

Upgrades to Consider with Air Conditioning Installation

July 31st, 2014

Purchasing a new air conditioning system may be a big investment, but the upgrades you choose upon installation can save you a lot of money every month. Choosing to replace an older system may be a positive experience when you upgrade to an air conditioner with a high SEER or replace your older thermostat with a digital, programmable model, both of which are available when you choose air conditioning installation in South Miami with Air on Demand.

High SEER

If you need a new air conditioner, you can select a system with a high SEER, which means you’ll notice immediate savings. The SEER (Seasonal Energy Efficiency Ratio) is a measure of an air conditioner’s efficiency calculated by dividing the cooling capacity of an AC by its total energy consumption. This rating system is printed on the EnergyGuide of every air conditioning system. The efficiency of an air conditioner reduces over time, and newer systems generally have much higher SEERs than older systems.

Digital, Programmable Thermostats

Some people choose to keep their older thermostat with new AC installation, but if you’re holding onto a manual thermostat with dials and sliders, you may lose money and sacrifice some comfort. These thermostats are often difficult to read and calibrate, so you may never get the temperature set to where you want it. Furthermore, these thermostats may cost you. Even if you set the temperature only one or two degrees lower than you need it, you will spend much more on cooling costs than you should.

A new, programmable, digital thermostat can help save you money and can keep you more comfortable in your home. Digital thermostats are easier to read for greater accuracy, and programmable thermostats allow you to set the temperature to your preferences far in advance. Rather than keep the air conditioner on when you leave the house, you can set the thermostat to come on thirty minutes before you arrive to reduce energy consumption.

To install an AC in South Miami, ask the experts at Air on Demand which upgrades are best for your home. To see more energy savings with your new air conditioner, give us a call today!

What Is the Difference between Rooftop Units and Other ACs?

July 21st, 2014

When it comes to commercial air conditioning, the great workhorses are rooftop units. People are accustomed to seeing rows of air conditioner cabinets along the top of office and retail buildings. Some commercial buildings still use “split” systems that are similar to the ones seen in residential housing, while restaurants and bars often use ductless heat pumps that send conditioned air wall-mounted blowers that are connected to an outdoor condenser. But the rooftop unit, because of its space saving quality and ease of service, continues to be the most popular for business use.

What actually differentiates rooftop units from other HVAC systems, aside from their location? We’ll look into this, and it may help you make the decision for what sort of heating and cooling system you want for your business location.

For detailed information on how rooftop units in Coral Gables, FL will work for your company, call Air on Demand and ask about commercial HVAC services today.

What Sets the Rooftop Unit Apart From Other ACs

Rooftop units are what are known as package units in the HVAC industry. A package unit is set apart from a split system, which is the common type of air conditioner/heat pump found in houses. A split system has an outdoor cabinet and an indoor cabinet with different sets of components. The outdoor cabinet has a compressor, fan, and a condenser coil; the indoor cabinet has a blower, dampers, air handler, and evaporator coil, and hooks into the ventilation system.

With a rooftop package unit, all the components are housed in one cabinet stored on the top of the building. Both sets of coils, to release and absorb heat, are in the cabinet along with the compressors and the fans. The unit connects directly into the building’s ventilation system to circulate the air.

Rooftop units can be configured either as air conditioners, or as heat pump capable of both heating and cooling. With installation of a humidistat on a rooftop unit, it can also control humidity and permit the ventilation of fresh air into the system; this is a benefit that split systems do not have, and it is a great asset for increasing indoor air quality.

Rooftop units come in an enormous array of types and sizes, and you will need to have professionals help you select the right unit or units to install for your business. The comfort of your employees, customers, and/or clients rests on making the correct decision for rooftop units in Coral Gables, FL, so make sure you have an experience commercial HVAC company handling the work for you: call Air on Demand. We carry Trane rooftop units from 1.5 tons up to 162 tons of cooling capacity.

How to Choose the Right Air Conditioning Installation Service

July 15th, 2014

If you need a new air conditioner in South Miami, FL, there’s no time to wait! You need to find an air conditioning installation service right away, but how do you choose the right one? Air conditioning installation is a delicate process, and you want to be certain your technician will be honest and dependable. The following guide can help you choose an AC technician that will do the job right.

Air conditioning installation is an intricate process that should always be handled by a professional. If your air conditioning system is not installed correctly, you may run into many costly repair issues later on or high energy bills. For example, if your AC unit is not sized properly for your home, your unit may have to work harder to keep you cool. This not only drives up energy costs, but also causes some parts to wear out sooner than they should, which means you’ll have to pay to replace them sooner than is necessary. For this reason, you should never attempt installation on your own.

The air conditioning installation service you choose should discuss pricing options with you during your scheduled estimate. Air conditioners are available within a number of price ranges. If you’d like to save energy every month, ask your AC technician if there is a system available with a higher SEER (Seasonal Energy Efficiency Ratio). A lower SEER may help you save on the initial cost of installation, but your energy bills may be higher every month.

Furthermore, the air conditioning installation technician you choose should discuss all of the different air conditioning systems available to you. Your technician should be willing to discuss ductless and central air conditioning options for homes with unique needs.

You should also choose an air conditioning installation service that offers repair and maintenance services as well. If your technician does a good job, you may choose to contact the company for future repairs. This will be easier for you and will help you be sure the technician knows the ins and outs of the particular system installed in your home.

Signs You Need to Call for Commercial HVAC Services

July 10th, 2014

If your business is housed in a building with a properly installed HVAC system to provide heating and cooling, you shouldn’t encounter many problems with operating. However, because commercial systems are required to run for many hours—far more than any residential system—they will suffer from a large amount of wear and tear. Although regular maintenance will go a long way to alleviating this issue, you may still need to call in professionals to handles repairs.

There are some of the signs that you may need call on commercial HVAC services in Kendall, FL. Make sure that you contact a company with experience on heating and cooling businesses; this isn’t a job that anyone familiar with residential HVAC can handle. Look to Air on Demand and our NATE-certified technicians for the next time you need service to restore the comfort of your workplace.

Here Are Signs to Call for Commercial HVAC Services

  • Uneven temperatures: A common issue that can occur in commercial HVAC systems is trouble with the zone dampers and the thermostats. Commercial systems are larger than residential ones, and they need to use multiple thermostats to control a large number of zones. When people in the workspace start to complain about rooms that are too stuffy or too cold, the issue may be with the zone control. It’s also possible that the packaged rooftop unit has lost cooling/heating power (such as because of leaking refrigerant). Call for professionals to look into the uneven temperatures.
  • Appearance of water condensation in the workplace: This is an issue specific to a Miami summer. Because air conditioning helps to combat high humidity levels (when it absorbs heat from the air, it also absorbs moisture), when it starts to malfunction, humidity inside the building will rise. This will first show up as condensation along windows and other external surfaces. At the first sign of condensation problems, call for assistance from repair professionals.
  • Strange smells from the vents: Acrid or moldy/musty smells coming from the vents usually point to repair issues. The burning smells sometimes point toward motor and electrical problems inside the rooftop unit(s) that will need to have technicians replace the burnt out parts. Musty and moldy smells usually indicate that there are leaks and breaks along the ventilation system that will require sealing. Bring in commercial specialists to look over the system and determine where the issues are and then fix them.

Air on Demand takes pride in the skill of our team for providing quality HVAC services in Kendall, FL. When the comfort of your employees, customers, clients, and/or tenants is in jeopardy because of a malfunctioning HVAC system, make us your first call.

The Famous Painting of the Declaration of Independence Isn’t What You Think It Is

July 4th, 2014

If you grew up in the United States, you probably first saw John Trumbull’s painting of the Signing of the Declaration of Independence in an elementary schoolbook. This oil-on-canvas 12’ x 18’ painting hangs in the rotunda of the United States Capitol in Washington, D.C. It is one of the most famous symbols of freedom in the country and almost every citizen can conjure it from memory.

Except… the painting isn’t of the singing of the Declaration of Independence. The actual title of the work is Declaration of Independence, and although it does portray an important moment in the history of the document that announced the Thirteen Colonies’ decision to break away from British rule, the event in the painting occurred on June 28, 1776, not July 4, 1776.

John Trumbull, a Connecticut native who fought in the Revolutionary War and whose father was the state governor, was commissioned to create the painting in 1817. He did painstaking research on the figures in the picture and also visited Independence Hall to see the actual chamber where the Second Continental Congress met. Trumbull only included 42 of the original 56 signers, because he could not find adequate likenesses for 14 or them, and added a few figures who were not present (most of whom declined to sign the actual document). In fact, the men depicted in the painting had never been present in the same room at one time.

So if the painting does not portray the signing of the Declaration of Independence, what is happening in the image? The Trumbull’s scene depicts the presentation of the draft of the declaration to the Continental Congress for editing and approval. The five-man drafting committee (John Adams, Roger Sherman, Robert R. Livingston, Thomas Jefferson, and Benjamin Franklin) is handing over their finished work, which congress would then edit carefully over the next few days before voting on it and signing it on the day that we now celebrate as the start of the United States of America.

One last, odd, fact: two of the five-man drafting committee, John Adams and Thomas Jefferson, both died on July 4th—although many years later.

Our family at Air On Demand hopes that your Fourth of July (or Twenty-Eighth of June if you decided to start celebrating early) is a memorable and happy one.

How Can a Ductless Air Conditioning Installation Save Me Money?

June 27th, 2014

Here in Doral, FL, you need a reliable air conditioner to keep your home cool all summer long. However, your current air conditioning system might be costing you a lot of money in the summer months. If your home AC system causes your energy bills to soar this summer, consider a ductless system to cut down on your energy consumption.

If you decide a ductless mini split system is best for you, contact Air on Demand for ductless air conditioning installation service.

What Is a Ductless Mini Split System?

A ductless mini split system provides a flexible solution for both cooling and heating your home. It’s divided into two parts: an outdoor compressor/condenser unit and one or more indoor units. Instead of using ducts throughout the home, multiple indoor air handlers can be installed in different rooms or zones to provide varied temperatures in each area.

The size of these indoor air handlers contrasts significantly with those utilized by central air units and heat pumps.

How Can a Ductless System Cut Energy Bills?

One way that ductless mini split systems help you to save money every month on your energy bill is by allowing you to control the temperature of each room. If your family is gathered in the living room, for example, you may choose to adjust the temperature in areas of the home that are not in use to cut cooling costs.

Another way a ductless system helps you save on your energy bills is by cutting potential energy loss associated with AC systems that utilize ducts. Faulty or leaky ductwork accounts for a large percentage of energy loss, forcing central AC systems to work harder to compensate and costing you more on your energy bills.

To start saving money on your energy bills with a ductless air conditioning installation, contact Air on Demand today!

3 Causes of Low Air Flow

June 20th, 2014

One of the major warning signs that an air conditioning system (or a forced-air heater) has developed a serious malfunction is when the airflow coming from the registers into the rooms drops. You will probably first notice this as uneven cooling in the rooms and an extended period required to reach the desired temperature. When you check on the vents and find that air is only sluggishly coming out, it’s time to call for experts in AC repair to investigate the problem.

There are a few different reasons that the airflow from your cooling system might drop, and it will take trained professionals to identify the specific cause and address it. Rely on the HVAC experts at Air on Demand when you need air conditioning repair in South Miami, FL. We have a staff of NATE-certified technicians to make sure you receive the best quality repairs for your cooling, done fast and right the first time.

3 Possible Reasons for Low Airflow

  • Clogged air filter: This is the most common cause of low airflow, and also one that is easily preventable. The air filter in your air conditioner catches particles inside the air that come through the return vent to prevent them from harming the interior of the cabinet. After a month of regular cooling, the filter will have a large amount of dust, lint, and other debris inside it, and this will close off airflow into and out of the system. Change the filter once a month throughout the summer (and any other time that the AC runs regularly) to keep this from happening, and call for repairs if it has caused a severe reduction in airflow.
  • Leaky ductwork: The problem may not originate inside the air conditioner itself, but from the ventilation system that distributes the air. Leaks from breaks and holes inside the ductwork will cause air pressure to drop inside the ventilation system, sometimes as much as 50%. This needs special ductwork repair technicians to handle: they will track down the leaks in the ventilation system and seal them.
  • Blower troubles: The blower in the air handler (the indoor unit of an air conditioner) sends air from the return vents past the evaporator coil and then into the ductwork. If the blower begins to fail due to problems with its motor or the electrical system, the airflow will start to plummet. This also means less efficient cooling because of the reduction of air across the coil. Blower problems need skilled technical work to fix.

Our professional team at Air on Demand offer quality air conditioning services in South Miami, FL. You can count on us to solve whatever problems you have with your airflow this summer (and we can take care of airflow from your heater as well during the winter). Give us a call today to schedule your next AC service appointment with us.
