Common Indoor Air Quality Problems

Monday, January 7th, 2013

Maintaining even, comfortable temperatures in your home is an important goal. However, many homeowners fail to realize the effect that other factors have on the comfort levels in their home. At Astro Air Inc. we strongly believe that the quality of the air that you breathe in your home is every bit as important as the temperature. Unfortunately, many homeowners do not understand the causes of their indoor air quality problems, and sometimes they sneak by completely undetected. If you are at all concerned about the quality of the air that you and your family members breathe in your Boynton Beach home, call us today. We have the solutions to all your indoor air quality problems.

One of the most common issues that homeowners face with their indoor air quality is the presence of airborne pollutants in their home.  There are many tools, products and services that can help eliminate the pollutants that do find their way into your home from the air that you breathe, though.

Air cleaners are one of the most straightforward ways in which you can improve indoor air quality. These devices remove particles from the air that you breathe in a variety of ways. Mechanical filters trap them on a filtering material, while electronic air cleaners use a static charge to trap the pollutants on a collector plate. Either way, your air is more clean and pure.

Another common issue that your air quality may suffer from includes biological pollutants such as allergens and even mold. UV germicidal lights use small amounts of UV radiation to target and destroy such pollutants. Keep your air and the inner surfaces of your air ducts clean with the use of these innovative devices.

Many homeowners dismiss humid air in their homes as a minor nuisance. It can be, in fact, a serious problem. Humidity can make air stuffy and uncomfortable, cause wood rot and even promotes the growth of mold in your home. Protect your property, health and home from humidity with a whole house dehumidifier.

If you have any further questions about indoor air quality and the common problems that homeowners face in Boynton Beach, call Astro Air Inc.. We have all the answers you need to improve air quality in your home. Let us help you live more comfortably.

Air Conditioning FAQ: What are Variable Refrigerant Flow (VRF) Systems?

Monday, October 15th, 2012

At Astro Air, we want to help our commercial customers save energy and money. That’s why we specialize in Boca Raton commercial HVAC services, and we install and maintain variable refrigerant flow (VRF) systems. If you own a commercial space, these systems are ideal. Here’s how they work.

VRF systems are more efficient than most HVAC systems on the market today. Air source VRF systems offer zone control and don’t need to use ductwork, which can cause air loss and poor indoor air quality. This makes them easy to maintain as well, which means that you don’t have as much operation cost.

They work much like any other ductless system. The “variable” part of VRF indicates that there are variable amounts of refrigerant that can be sent to each evaporator, and each evaporator is a part of a unit that is controlled by a thermostat in that zone of the building. In fact, some models include special inverters and dual compressors outdoors to maintain smooth operation and temperature levels throughout the building.

The zone control comes in with the option of shutting the units off in certain zones that are not used, which saves money and energy. Because there’s no ductwork, there’s no need to worry about affecting the pressure in the ductwork. In addition, VRF systems don’t use large fans, which means that they are quieter and even more efficient. The savings you get from that level of efficiency are significant. Not only that, but you also are helping the environment by not using as much energy.

Whether you are building a new commercial building, or remodeling an older one, VRF systems may be just the right solution for your commercial heating and cooling needs. ideal for retrofitting older buildings without destroying the original integrity.

Let Astro Air help you save energy and lower operation costs with a new variable refrigerant flow HVAC system. Call the Boca Raton commercial HVAC experts at Astro Air today!

The Room by Room Benefits of Ductless Splits AC

Monday, May 14th, 2012

Ductless splits air conditioners are designed to eliminate the need for ductwork in a home where space is at a premium. Usually homeowners with older homes – those built before the 1970s – have very little space to work with when it comes to installing the ductwork a traditional central air conditioning system requires. As a result, cooling costs can be extremely high each summer and the house usually isn’t comfortable during these months.

Ductless air conditioning offers a solution to most of these problems. Not only does the technology not require ductwork to be installed; it allows for multiple in-room units on a single compressor and it costs significantly less to operate compared to window AC units.

Ductless System Specifications

Ductless air conditioning systems consist of two major components: a compressor which is placed outside and indoor evaporators. With the use of inverter technology, these systems can support multiple evaporators – usually as many as four to a single condenser. This means you can have a single outdoor unit supporting cooling four separate rooms of your home at the same time.

Each of those indoor evaporators acts as a heat pump, allowing you to both heat and cool the room year round. And because the only connection needed between evaporator and condenser is a single conduit, the installation is significantly easier than it would be for a ductwork based central AC system.

Room by Room Benefits

While the primary benefit of a ductless system is the fact that it allows you to install air conditioning in multiple rooms of your house without the need for ductwork, there are other benefits. Not only do you get a much higher energy efficiency rating than you would with traditional window units (many ductless systems are rated at 16 SEER or higher while window units are frequently as low as 10 or 11), but you can control each unit individually. So if a room upstairs doesn’t need to be cooled during the afternoon hours, simply turn off the thermostat in that part of the house and save money.

There are some factors to consider when installing a ductless system. How many rooms do you need cooled? How warm does it get in the summer? Will the system be used for heating in the winter? These are all things you may want to discuss in greater detail with your AC contractor when you call for an estimate.

HVAC Tip: Heat Pump Air Duct Requirements

Monday, May 7th, 2012

Heat Pump Technology

Among the systems getting a fresh look today are heat pumps, a device that transfers thermal energy from one location to another, usually in the direction of from a colder temperature to higher and generally the opposite of the natural flow.  While compressor-driven air conditioners and freezers are technically heat pumps, “heat pump” is the term that usually implies one of the less-common devices in the class that are not dedicated to refrigeration-only.

A heat pump that maintains a thermally conditioned-space can be used to provide either heating or cooling, depending upon whether the environment is cooler or warmer than the conditioned-space.  Typically pumps utilize some thermal energy from the environment itself, such as the natural heat in the outdoor air.

By simply transferring the energy rather than producing it, heat pumps are being more seriously considered as attractive alternatives to provide an efficient and clean system for conditioning public and living spaces. Many people in Palm Beach are using heat pumps for both heating and cooling their homes.

Change of Use

Since a heat pump typically moves conditioned air through ductwork, the advantages of the change are much more realistic with a system of pre-existing ducts such as a forced air furnace or central air-conditioning unit.  While a heat pump often requires a larger volume of ducts, the old network of metal tunnels was often over-sized for inefficient furnaces and should do fine in a conversion to a heat pump.

The Right Data

Since the required formulas are dependent upon variables such as size, distance, volume and oomph, the design is strategic and makes all the difference.  Consulting with a trained and experienced professional such as Astro Air Inc. is critical to the success of the conversion to a heat pump system in Palm Beach.

Air Conditioning Tip: Causes of AC Short Cycling

Monday, April 30th, 2012

Air conditioning short cycling is a common problem wherein an air conditioning unit will have either short run times or short off times.  This type of quick movement back and forth between being on and off–or rather starting and stopping rapidly–can be detrimental to the overall life of your Palm Beach home’s AC unit, and is also not energy efficient.

AC short cycling can have many causes, and many fixes.  Below are the main causes for air conditioning short cycling, which can be checked, diagnosed, and fixed quite easily.

  • AC Refrigerant Leak:  There could be a refrigerant leak somewhere within the AC unit.  A temporary fix might be to add refrigerant and recharge the air conditioning unit, but long-term, a Palm Beach HVAC specialist will need to be contacted in order to find and fix the leak properly, ensuring excess money is not paid to continually add an unnecessary amount of refrigerant.
  • AC Coil Icing: This means that the evaporator coil or cooling coil has become encrusted with ice or frost and is causing the unit to malfunction by turning on and off in short bursts.  Turning off the unit completely and letting the ice melt, then checking and replacing dirty filters can oftentimes fix this problem.
  • AC is Oversized:  The amount of power needed (or the BTUs needed) to cool a space is directly proportional to the size of the space or room which is being cooled.
    • If AC short cycling has been a constant problem since day one of an AC system installation, it is entirely possible that the A/C unit is too large for the space which it is cooling.  This could mean contacting an HVAC technician to have the unit analyzed and a new, smaller unit put in.
    • If A/C short cycling is a relatively new problem, some possible causes could be: closing or opening doors which previously were not closed or opened frequently, or the addition of partitions within rooms which effectively makes the room size smaller.  This could mean simply adjusting the thermostat, or the blower fan to a lower speed to compensate for the change, or opening interior doors to increase the size of the space which is being cooled by the AC unit.
  • AC Control Board Problem:  While less likely, the problem could be in a control board or control switch which has been damaged, thus causing erratic and rapid starting and stopping cycles.  In this case an HVAC technician would need to be contacted in order to replace the broken control switch.
  • AC Compressor Damage or Start-Up Issues:  Some AC systems have hard-starting compressors which take time to re-pressurize properly after shutting down.  If the AC system is being turned on or off manually on a frequent basis, the compressor might have a hard time restarting because the high pressure which had built up on the previous on-cycle had not had a chance to come down to normal levels again.  An easy way to diagnose this problem is if after leaving the AC unit shut off for thirty minutes, the unit works properly after being turned on again.  To help this compressor issue, an HVAC service technician can add a starter capacitor to the AC unit.

These and other AC short cycling causes can be checked, diagnosed, and fixed quite easily by an experienced Palm Beach HVAC professional.
