Don’t Wait Until the End of the Season for AC Repairs

Monday, March 4th, 2019

service-timeLet’s say you’ve just noticed some issues with your AC. But at the same time, you also plan to get AC maintenance at some point closer to the start of summer. So is it better to hold off on the repairs and lump them all in with the upcoming maintenance appointment, or is it better to have that maintenance now and pay for repairs sooner than anticipated?

The latter certainly sounds less convenient, but in our professional opinion, it’s the best course of action—and we’re not just saying that because we’re an AC repair company in South Miami. Putting off repairs, for any reason, is always going to cost you more in the long run. Here’s how:

What Is the Best Type of Heater for a Swimming Pool

Tuesday, January 6th, 2015

*Air On Demand no longer offers pool heater services. Please visit our service page to learn more about our Florida air conditioning services.

When you bought a new pool or purchased a home with a pool in South Miami, you may never have expected you would need a pool heater. But as the months went by, you probably quickly discovered that using the pool in the summer months can be an unpleasant experience. Pool heaters can allow you extra months of enjoyment, exercise, and family fun, but there are actually a few different types of swimming pool heaters to choose from.

When you decide it’s time to heat up your pool for the winter, call the experts at Air on Demand for expert installation and advice on pool heaters in South Miami.

Gas swimming pool heaters used to be the norm, using the natural gas from the utility company to power the outside unit. Gas units operate using combustion to generate heat and a heat exchanger to transfer that heat to the water. Water continuously cycles through the unit and back to the pool. Gas swimming pool heaters are still widely used, but they’re generally considered best for heating a pool for only a short period of time. This is best for pools that are used infrequently and need a type of heater that will work quickly.

Heat Pump Pool Heaters

But there are other options for you to choose from, and it’s better to let a professional help you select the proper unit. One of the most popular types in use today is the heat pump pool heater. These are extremely efficient because they don’t actually have to generate heat. Instead, they use a refrigerant blend to absorb heat from the outside and move it to the condenser coil. As it condenses it gives off heat, which transfers to the water cycling through the unit and back to the pool repeatedly.

Heat pump pool heaters are one of the most efficient and effective units out there, but it’s important to let a professional help you to make a final decision. Any pool heater must be sized to meet the needs of your pool and the outdoor climate.

Should I Replace My AC Even If It Still Works Well?

Wednesday, November 5th, 2014

Properly maintaining your air conditioning system can help extend its life. However, an aging system does have some drawbacks that maintenance and repair can’t fix, and at some point you may need to consider an air conditioning replacement in South Miami. Installing a new air conditioning system is not a DIY kind of project, so call the people you can trust: Air on Demand.

Reasons to Consider a New AC


Most air conditioners have a lifespan of 10-12 years; with excellent maintenance, the lifespan can stretch to 15 years. While your existing air conditioner may be working fine now, it is bound to start developing problems common to aging systems. These problems may include an inability to cool properly and a need for constant repairs. Air conditioners are durable, but they aren’t meant to last forever. If your system is more than 12 years old, you may want to see what a new system can do for you and your home.


Today’s air conditioners are much more energy efficient than ones produced just 10 years ago. Additionally, the federal law changed in 2006, mandating that all air conditioners have a minimum SEER of 13; before this law changed, the minimum SEER requirement was 10. If your system is 8 years old or older, you may be losing out on significant energy savings.

Refrigerant Type

One of the main problems with air conditioning has been the use of R-22 refrigerant. There has been a steady phase-out of the use of R-22 since the 1990s, but it wasn’t until 2010 that air conditioners could no longer be produced with R-22. Since 2010, the production has decreased significantly, and it can only be used for repairs. By 2020, R-22 will no longer be available anywhere. What does this mean for you? If your air conditioning system uses R-22 refrigerant, you are going to have to install a new system by 2020, because the new refrigerants on the market are not compatible with an R-22 system.

If you aren’t sure whether or not it’s time for a new air conditioning installation in South Miami, consult with a trained professional. The experts at Air on Demand bring over 3 decades of expertise to each customer – call us today!

Upgrades to Consider with Air Conditioning Installation

Thursday, 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.


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!

How to Choose the Right Air Conditioning Installation Service

Tuesday, 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.

3 Causes of Low Air Flow

Friday, 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.

Common Air Conditioning Problems in the Spring

Friday, April 25th, 2014

Air conditioners come on earlier in Florida than in most parts of the country. Although summer will have even hotter temperatures and higher humidity, spring nonetheless can tax our ACs and create problems before the big heat arrives. Coming out of its winter’s rest can also pose difficulties for an air conditioning system. Here are some of the more common AC problems we encounter during the spring on our repair visits.

Make sure you call in South Miami, FL air conditioning specialists whenever you encounter a springtime slowdown in your AC, no matter what you think is wrong with it. We have NATE-certified technicians on staff who can deliver you top quality repair work.

Some Spring AC Problems

  • Leaking refrigerant: If you see ice along the indoor coils, notice a drop in cooling power, or hear a strange hissing sound coming from the air conditioner’s cabinet, then you may have a problem with refrigerant leaking from the system. This sometimes happens because of formicary corrosion that developed on the system during the winter and has created minute holes that allow refrigerant to escape. Call a repair technician to locate the leaks and seal them, and then recharge the refrigerant to its proper level.
  • Dust and dirt on the motors: If the air conditioner did not have its air filter changed at the beginning of spring (it should be changed every month during air conditioning season), then dirt and dust contamination may have entered the cabinet and affected the motors. This will make the motors work harder, and the strain can lead to them burning out and requiring replacement. Call for repairs the moment you hear screeching and grinding noises from inside the cabinet, or an acrid smell coming from the vents, as this can indicate a motor on the verge of failing.
  • “Hard starting”: If the air conditioner seems to struggle when it comes on, then it’s probably hard-starting and draining energy. Hard starting can occur because of a number of different issues, although the most common is a failing start capacitor, the device that transmits voltage to the compressor motor to start it up. If the capacitor fails entirely, the compressor motor won’t be able to come on. Repair technicians can swap out the old capacitor for a new one—but make sure you call for assistance as soon as you notice the hard starting.

Most AC repairs are not difficult for professionals and the work will not require long to complete…as long as you acted quickly to summon repairs. The longer you wait, the worse the repair will grow, and it will lead to other repair needs as well.

Call on Air on Demand for professional air conditioning service in South Miami, FL to help you take care of all the “spring fever” problems in your air conditioning. Give us a call today and schedule your next service appointment.

Air Conditioning Basics: What You Should Know about Refrigerant Types

Monday, February 24th, 2014

You probably don’t give your air conditioning in South Miami, FL more thought than necessary: as long as you schedule regular maintenance, change the air filter once a month during the warm months, and have professionals do prompt repairs when it malfunctions, your AC should continue to work for you for many years.

However, you can benefit from some extra knowledge about how an air conditioner operates, since it can help you understand why certain malfunctions occur. A key part of understanding AC operation is knowledge of the refrigerant inside it, the chemical blend that allows the system to move heat from inside your home to outside your home. Here’s what you should know about refrigerant types, courtesy of our AC specialists at Air on Demand.

The development of refrigerant

Willis Carrier invented the first electromechanical air conditioning unit in 1902, and it used water as refrigerant. However, water has too high a boiling point for energy efficient performance, so other chemical soon replaced it. The early air conditioners used ammonia, methyl chloride, or propane. All of these worked more efficiently at changing from liquid to gas and back again, but they had serious drawbacks: they were either flammable or toxic, and leaks could lead to dangerous accidents. This made ACs unsuitable for home use.

In 1928, the first non-flammable, non-toxic refrigerant blend was created, R-22.

The dominant blend across the globe is R-22 (the name refers to the molecular composition of the chemical), a hydrochlorofluorocarbon. However, R-22 is a greenhouse gas and contributes to ozone depletion, so in the United States it is being gradually phased out with the goal of 99.5% elimination by 2020. The main replacement blend—most likely the blend cycling through your air conditioner right now—is R-410A, also known as Puron and EcoFluor R410—is a mix of difluoromethane and pentafluoroethane. Because R-410A contains no fluorocarbons, it does not deplete the ozone layer.

Refrigerant leaks and recharging

Whatever refrigerant flows through your AC, it has a fixed level—called the refrigerant’s “charge”—that cycles in a closed loop through the system. The process of evaporation and condensation that provides you with cooling does not use up the refrigerant charge. However, leaks can occur: punctures in the coils, loose connections, breaks in the compressor. Leaking refrigerant will cause ice to develop along the indoor coils, and when this happens you need to call for professional repairs. Not only do you need an expert to seal the leaks, but the expert must use the proper refrigerant blend to replace the lost charge.

For all your repair needs for your air conditioning in South Miami, FL, trust to Air on Demand.

How Is a Swimming Pool Heater Sized?

Monday, January 6th, 2014

*Air On Demand no longer offers pool heater services. Please visit our service page to learn more about our Florida air conditioning services.

A swimming pool doesn’t have to be a seasonal luxury, especially in Miami, with our wonderful year-round weather. With the proper pool heater keeping the water warm and inviting, you can enjoy your pool through cool and overcast days as if it were summer.

However, a pool heater is only worthwhile if it’s the right size to heat up the water in the pool. Proper sizing is an important part of pool heater installation, which is one of many reasons you should only hire professionals to handle the job. Air on Demand has provided heating services for more than two decades; put your trust in us to find the right type and size pool heater for South Miami, FL to keep you happy every month of the year.

Similar to how the power of air conditioners is measured, swimming pool heaters are rated by their output of BTUs (British Thermal Units). A BTU is the energy required to change the temperature of 1 pound of water by one degree Fahrenheit. (To compare to another measurement of heating, 1 BTU = approx. 1055 joules.) To correctly size a pool heater, an installer must determine how many BTUs the heater must create to raise the pool’s temperature to a comfortable level.

This isn’t only a question of figuring out the volume of water in the pool. Surface area is crucial. The pool loses heat rapidly off the surface, and the pool heater must heat the water faster than this loss. Once the heater reaches an ideal temperature, it must then maintain only enough power to compensate for the surface area loss.

The next factor to consider is temperature rise, which is the desired water temperature minus the ambient air temperature.

The technician now takes the surface area and the temperature rise and uses a chart to determine the required heating output per hour, measured in BTUs.

It doesn’t end there, however. Pool heaters have an efficiency rating their manufacturers set that measures how well the heater transfers its energy to the water, expressed as a percentage. The technician will multiply the BTUs required per hour by this efficiency rating to find the heater that can provide the correct amount of heat.

Does this sound like too much number-crunching for you? You don’t have to worry—this is why you bring in experts like those at Air on Demand to install your pool heater in South Miami, FL. Contact us today, and we’ll find the right heater for you in no time at all, and you won’t even have to touch a calculator.
