How Rooftop Units Are Different from Other HVAC Systems

Wednesday, September 24th, 2014

If you need a new HVAC system for your home or business, it can be tough keep track of all of the different types of systems available today. Here at Astro Air Inc., we want to help you decide which unit is right for you by keeping you informed about your options. Many homes and businesses have unique space needs or large heating and cooling needs for which a rooftop unit may be the best choice. In this guide, we’ll look at a few of the key differences between rooftop units, which are typically used in commercial applications, and other types of HVAC systems so that you can decide whether this is the system for you.

Packaged System

Rooftop units are also known as packaged units because every component comes packaged together in a single cabinet. Standard residential air conditioners require both an indoor and outdoor unit to remove heat from the home. The furnace or alternate heating source is usually separate. However, packaged units combine every component into a single cabinet. It connects directly to the ducts to eliminate the need for indoor installation, which may be necessary for some homes. This is great for businesses because every part can be found in one location for any needed repairs, so that you can get back to work quickly.

Heating and Cooling

With the exception of heat pumps, which can both heat and cool a space, most HVAC units can only do one or the other. Rooftop units are unique in that the heating system and cooling system are often combined into one cabinet. This is ideal for large commercial buildings that can accommodate a multi-ton unit on the rooftop.

Modular Units

Finally, rooftop units tend to be modular, meaning a technician can add or take away modules to accommodate the changing needs of a business. With other HVAC units, if your needs change you may need to replace the entire system. But modular rooftop units are designed with businesses in mind. If your business expands, a technician can simply add another module to increase the cooling capacity of your unit.

Repair Problems that Can Occur in an Air Conditioner’s Condenser

Wednesday, September 17th, 2014

The large outdoor condenser unit is perhaps the most noticeable portion of your air conditioner, but it may sometimes get neglected. Large debris and vegetation located near this unit can cause components to struggle, so you should take care to clear any objects that may get in the way of your condenser. But while this may prevent some problems, others may develop over time and require the attention of an experienced professional. Be sure to call for air conditioning repair at the first sign of any of the following problems.

  • Broken Condenser Fan/Fan Motor: The fan helps heat to dissipate from the refrigerant into the outside air. So if this part is damaged in any way, you may only feel warm air coming through the vents inside. If a fan blade is bent or loose, or if the motor is malfunctioning, this part needs immediate attention. The problem may be anything from a lack of lubrication to debris in the motor to an electrical problem.
  • Faulty Compressor: The compressor is one of the most important components of your air conditioner, and you want to keep this part in top working order to avoid repairs. But if any other part of your air conditioner is broken, your compressor may become overworked and break down, which means you’ll likely need to replace this part entirely. To prevent this, call for repairs at the first sign of damages anywhere in your system, including unusual sounds and limited cooling.
  • Dirty Coil: One of the most common problems that causes homeowners to call for repairs is when a coil is too dirty. The indoor coil helps refrigerant to absorb heat while the outdoor coil helps it to release into the air. If the outdoor coil is too dirty, which happens somewhat easily due to its location outdoors, heat cannot dissipate, and you may feel warm air from the vents. If you schedule regular AC maintenance, the technician will clean and adjust this coil to keep problems from occurring later on.

How to Tell That You Need Duct Sealing

Wednesday, September 10th, 2014

Problems with your ductwork can look like a lot of other things, and because your ductwork isn’t visible, it can be one of the last suspects on the list. However, there are some indications your ductwork gives when things aren’t going so well. One of the ways to reduce air loss and restore good operation to your ductwork is with duct sealing for your Wellington property. Shoddy workmanship and improper installation are two reasons that ductwork can become faulty, so be sure to hire trained, certified and trusted professionals for your duct sealing: call Astro Air, Inc.

Signs You May Need Duct Sealing

There are a few common signs that it may be time to seal your ducts:

  • Whistling/screaming noises coming through your vents – air leaks in your ductwork can cause a whistling or screaming sound as air escapes through holes and cracks.
  • Hot and cold spots – uneven cooling can indicate that cooling is not reaching certain rooms or areas in your home due to leaks or disconnections.
  • High energy bills – air loss due to faulty ductwork can be significant, and your air conditioner has to compensate for this loss. Recouping the lost air means your AC has to work harder, and when your AC works harder, it uses more energy to do so.
  • Poor indoor air quality – leaky ducts not only lose air, they pull in all kinds of particles and pollutants that can affect your indoor air quality. This can be a serious problem for allergy sufferers in your home.

How Are Ducts Sealed?

Your technician seals holes and cracks in your ductwork using a fibrous adhesive called mastic. Mastic is thick, and is applied with a paint brush. Once the mastic is applied, a piece of fiberglass or foil tape is placed on top of the mastic. The mastic is left to cure (dry) and when it does, it forms a hardseal.

Leaky ductwork can compromise your comfort and indoor air quality while costing you money in monthly energy. Scheduling a professional duct sealing for your Wellington home can help to reduce or even eliminate these problems. Call Astro Air, Inc. today and schedule an appointment with one of our experts.

The Fashion of Wearing White and Labor Day

Monday, September 1st, 2014

You may have heard about the fashion faux pas of wearing white after Labor Day. In the present, this tradition is usually treated as old fashioned and a joke. Few people will criticize you for wearing white articles of clothing after the first Monday in September, or even take notice of it except to wonder why it was ever a major concern at all.

Where did this tradition of white clothing going out of fashion after Labor Day come from, and why did it fade away like colorful fabric washed in a hot load in the washing machine?

In general, white makes sense for the heat of summer. Light-colored clothing reflects away the radiant heat of the sun, instead of absorbing it the way dark colors do, so for thousands of years of human history people have preferred to wear white clothing during the hotter months.

However, the idea of white as strictly fashionable during the summer season only emerged in the nineteenth and early twentieth centuries—the time when the very concept of “fashion” began to spread across the Western Hemisphere.

It was only the highest level of post-Civil War society in the U.S. that strict and often bizarre rules for fashion controlled whether someone was in with the “in” crowd. Compared to our ideas of what’s fashionable today, the Czars of Style in the 1880s were true despots. Things as trivial as sleeve length could determine whether a woman in high society—no matter her level of wealth—was fashionable or a pariah.

Wearing white during the only summer, when it was common for weddings and outdoor parties, was only of these restrictive society rules. When the U.S. government made Labor Day a federal holiday in 1894, the Fashion Czars gained a definite cut-off point for when wearing white was no longer “acceptable” in the upper echelons of wealthy society.

For many decades, this rule only applied to a small number of millionaire socialites in a few big cities, but in the 1950s it reached general fashion magazines that were read around the country and started to affect more people.

But time eventually broke apart this odd rule, and during the 1970s fashion became more individual. Some fashion legends, like Coco Chanel, also purposely rejected the restriction and wore white throughout the year. Today, the “no white after Labor Day rule” is little more than an amusing gag to tease friends, and almost nobody takes it seriously.

Whatever you choose to wear after Labor Day (and if it’s white, we won’t tease!), everyone here at Astro Air Inc. hopes you have a happy end of the summer and great plans for the fall!
