Choosing a Quality Air Filter for Your HVAC System

Wednesday, March 25th, 2015

Picking up an air filter for your HVAC system is as easy as going to your local hardware store and grabbing the one that fits your unit—right? Not if you want quality filtration for your indoor air quality. As it turns out, air conditioning and heating filters were not originally designed to improve our health. In reality, a filter’s first function is to keep debris out of the HVAC system. Imagine if a large piece of debris jammed a motor. This would result in a costly repair, which is why a filter first and foremost protects the unit.

Over time, professionals found ways to filter smaller particles out of the air with more advanced air filtration systems. The HVAC filter you use currently does provide some level of filtration. But it may not filter some of the most common contaminants that stay in the air you breathe. A quality air filter will help to eliminate some of the most common pollutants found in homes in Miami, FL. So how do you choose the right one?

Look for the MERV (minimum efficiency reporting value) rating! The MERV is a number 1-12 which lets you know how effective that filter is. A filter with a MERV of 3 is effective enough to eliminate dust mites but not pollen in many cases. A MERV of 4 can get rid of pollen, while it takes a MERV of 8 to eliminate mold spores that pass through the filter.

Unfortunately, if you choose a filter that has a MERV that is too high, it can damage your system. Your air conditioner needs a certain amount of airflow in order to work properly, and a filter that is too thick will prevent air from flowing in, which could lead to frozen coils and overworked parts.

It’s best to work with a technician when choosing the best filter for your health, family, and HVAC unit. The indoor air quality experts at air on Demand offer air filtration service, and can even help you to find an electronic filter for advanced purification.

Can I Tune Up My Pool Heater on My Own?

Wednesday, March 18th, 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 people picture the Florida climate, they probably assume that any home pool could do well without the benefit of a pool heater. However, as you well know, your swimming pool is simply not as enjoyable without it. Your pool heater allows you to make use of your investment no matter what the weather is like outside. However, if the heater is not in the best shape possible, it may not perform as well as you’d like.

When one part of your pool heater is not in top shape it simply cannot run as it was designed to. When just a little bit of refrigerant leaks, for example, you won’t get nearly as much power from your heater, as heat exchange is severely inhibited. Debris in the outside motor can delay heating ability and lead to a sudden breakdown which you may not notice until you jump into the pool on a cool day.

A simple tune up could keep such problems from occurring, especially when performed once a year by a professional. But some people would like to save some money and attempt pool heater maintenance on their own. The problem is that these systems are a bit more complicated than the average homeowner may expect. You’ll need a number of professional grade tools to check pressure levels, temperature output and efficiency. And without a working knowledge of heat pumps, knowing what to look for while disassembling the unit is simply too difficult for the average person.

Furthermore, attempting to work with a pool heater on your own may raise some concerns about safety. The average homeowner is not licensed to handle the most important aspect of a heat pump pool heater: the refrigerant. One must be licensed by the EPA in order to gain access to and dispose of refrigerant legally. And attempting to service a gas pool heater could prove dangerous.

At Air on Demand, our experts perform an 8-point pool heater maintenance check. This includes checking refrigerant levels, compressor performance, contactors, motors, and anything that might affect the efficiency of the system. They’ll let you know if you need to schedule any additional services, or if a replacement is soon in order.

What Is the Process Involved with Ductless Installation?

Wednesday, March 11th, 2015

If you are on the hunt for a new ductless heat pump, you may have heard how efficient these units are. Ductless mini split air conditioners move heat from inside of your home to the outside. And in cooler weather, ductless heat pumps can also move heat into the home from the outdoors. Most ductless units are rated highly for efficiency, especially for heating, since less energy is required to move heat into a space than to produce it.

Furthermore, you get the benefits that come with a lack of ductwork. Ductwork can bring dust into a home, and most ducts actually contain cracks and holes that keep air from moving into the home efficiently. A ducted unit may consume additional energy simply because of the flaws commonly found in the ductwork. Prevent the hassle that goes along with duct installation by installing ductless mini split installation in Pinecrest with the experts at Air on Demand.

The Process of Installation

Many people who schedule duct installation are most concerned with avoiding home renovations. Adding ductwork is time-consuming, costly, and changes the structure of the home. With a ductless unit, however, the installation often takes only a day. In fact, you’ll only need to make one small renovation: a hole in the wall through which technicians feed the refrigerant line that connects the inside and outside units.

The outside unit is just like the outside portion of any air conditioning system. This contains an outside condenser coil, a large fan, and the compressor, among other electrical components. Each unit can usually fit up to 4 indoor air handlers, which go high up on the wall of the rooms of your home. You’ll want an air handler in each room or zone of the house in which you require heating and cooling.

While the setup seems fairly simple, there is a lot that goes into it, including careful calculations and sizing, secure mounting of the indoor air handlers, and a precise refrigerant charge. Only trust your ductless mini split air conditioner installation in Pinecrest to experienced technicians, like the friendly team at Air on Demand. Call us today for quality ductless services!

The Benefits of Sheet Metal Ducts

Wednesday, March 4th, 2015

Ducts are necessary for forced-air air conditioning and heating. The ducts in your home serve as a pathway, so that conditioned air can travel into every room in your home. Duct installation is a long and involved process that requires careful planning, precise measurements, and the right type of tools and level of expertise. And you’ll need to select the right type of duct for the job.

Sheet metal ductwork is the most common type of ductwork installed in homes, but it’s not the only type. Some technicians prefer fiberglass duct board, while others prefer flexible ducts. So why does sheet metal remain king? Let’s take a look in today’s guide to installing new sheet metal ductwork in Homestead.

Proven Effectiveness

The main reason to choose sheet metal ductwork is that it is proven to be effective. If you have a new home or an existing home that needs a good set of ducts, sheet metal ductwork is long-lasting and durable. When installed correctly and properly maintained, you may not need any repairs for a long period of time.

Sheet metal ducts have a couple of other benefits as well. Many technicians find that they’re easier to install. There are so many sizes and types of fittings available that sheet metal ductwork should be efficient in nearly any home. Sheet metal ducts can stay cleaner for longer and won’t collect dust as easily as fiberglass duct board.

The Importance of Professional Installation

What you should always keep in mind is that professional installation is key to ducts that run efficiently. Without the right technician for installation, you may notice many problems with your air conditioning and heating system. Most homes have a problem with leaky ducts, which can cause an air conditioner or heater to run up to 30% less efficiently. Often, this is due to amateur installation rather than the work of a skilled HVAC contractor specializing in sheet metal ducts.

Call the experts at Air on Demand for installation of new sheet metal ductwork in Homestead. We install, repair, and seal ducts so that your air conditioning and heating system runs in the most efficient manner possible.
