What Is a DustStopper Filter and What Are Its Benefits?

Monday, January 27th, 2014

Having quality indoor air is important for your health and comfort, especially today when homes are essentially sealed from the outside air for energy efficiency. Ventilation is a key part of this, such as opening up windows. However, having open windows and doors isn’t often optimal in Florida weather, so it’s also important to have filtration devices installed in your home to clean your air.

In Miami, FL, DustStopper filters are an excellent choice for reducing the effect of airborne pollutants in your home. We recommend them to our customers and have seen the terrific results they provide. If you are interested in having a DustStopper Filter installed, call Air on Demand today and arrange an appointment with one of our trained technicians.

The DustStopper Filter: What you need to know

The DustStopper Filter is a specialized filter designed to have a low impact on the airflow of your HVAC system while providing quality removal of contaminating particles that would otherwise circulate through your air. A DustStopper filter has a high efficiency level capable of trapping 99% of all particles larger than 10 microns. Unlike the competing standard filters, such as MERV or HEPA filters, a DustStopper filter will not significantly reduce airflow and add extra stress on your heater or air conditioner.

The DustStopper manages to achieve this level of filtration combined with reduction of resistance on air flow through its special design of high performance synthetic fibers. Although these fibers are dense, they can pull in larger volumes of air than traditional filters, while still catching the dander, pollen, hair, and mold than would otherwise enter your air.

The DustStopper filter must be professionally installed to match the air handler on your HVAC system. After the installation is completed, you can arrange with the technicians a schedule for regularly replacing the filter. As with any filter, a DustStopper will eventually become congested with the particles it traps and begin to negatively affect your air quality. Regular replacements will make certain your DustStopper filter always works for you, not against you.

If you have further questions about the DustStopper filter and if one will work with your HVAC system, contact our installation experts at Air on Demand. They can help you find out how best to put a DustStopper filter in Miami, FL to work for you.

Components of an Air Handler

Monday, January 20th, 2014

The HVAC system in your home that provides you with cool air has a number of different parts that work together. One of the crucial parts is the air handler. This unit is responsible for moving conditioned air through the ductwork of your home and into the various rooms through vents. If an air handler malfunctions or breaks down, all the cooling power of your AC or heat pump will mean very little: you won’t receive the cool air that you need to stay comfortable in the Florida weather.

At Air on Demand, we recommend Trane air handlers for Miami, FL customers. Trane has been in business in 1913 and has a reputation for innovation and reliability. When you need a new Trane air handler installed in your home, call Air on Demand for proper unit selection and installation service.

Air Handler Components

What parts make up an air handler? We’ll look at them in a bit more detail so you can see the important job that these units perform. These are the components specifically found in the Hyperion™ line of Trane air handlers.

  • Blower/fan: The most basic component of an air handler is a large fan, also known as a blower. An electrical motor drives the fan. Hyperion™ air handlers have a variable speed motor that reduces noise and allows for a more even distribution of air. The Vortica™ blower found in Trane air handlers uses less energy than other blower models.
  • Evaporator coils: The important part of providing cool air for an air conditioner is the evaporator coil in the air handler. Refrigerant runs through these aluminum coils, and as air blows across the coils, evaporation occur that causes the coil to absorb heat. As heat is removed from the air, the air becomes cooler.
  • Air filtration: The filter in an air handler helps to filter dust from the air so it does not enter into your home. The Trane CleanEffect™ optional filter removes additional dust, pollen, dander, and other pollutants that standard filters do not affect.

Signs of a Problem with Your Electric Heat Strips

Monday, January 13th, 2014

Because heating our homes isn’t often on our minds in Florida’s warm weather as much as cooling them, we might not have given a lot of thought on how to keep our homes warm during the occasional cold weather. This is a reason that electric heat strips are a great option, since they allow you to convert an AC into a part-time heater at a low-cost… there’s no need for a second system.

Call Air on Demand for reliable heating repair in Miami, FL. We offer straightforward pricing so you always know you are getting a fair price. Call us for both excellent heat strip installation and heat strip repair.

How to tell you have problems with your electric heat strips

An electric heat strip looks like a series of coils. It attaches to the air handler on an air conditioning system and then heats the air coming out of the blower (with the AC in “fan only” mode). Essentially, it converts the air handler into a small-scale electric furnace.

Like any electronic system, a heat strip can malfunction and stop working. If your air conditioner is only blowing room temperature air when you turn on the heat strip, it’s most likely broken and will either need repairs or replacement. Because of the danger of an electric shock, you should only entrust this work to a professional.

If you feel the heat you get from your air handler is insufficient, although still present, the issue may not be a malfunction, but improper sizing of the electric strips. These units come in many different sizes, ranging in capacity from 8,500 BTUs to 85,000 BTUs—if you have the wrong one for the size of your home, you won’t get sufficient heat. (Or it could go the opposite way and you will receive too much heat, and will also likely trip a circuit breaker.) Always make sure professionals install your electric strips to avoid these issues.

Air on Demand has NATE-certified technicians on staff to help you when you have trouble with the electric heat strips in your house. NATE certification means repair technicians with the best training possible to deliver you the heating repair in Miami, FL that will restore the comfort in your home.

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.
