Air Conditioners

This can be a broad term; however, in the technical aspect, the air conditioner is the outdoor piece of a split system. There is a difference between air conditioners and heat pumps. Air Conditioners typically have mechanical cooling, meaning the compressor provides the cooling aspect of the system; heating is then provided by an electrical element in the air handler. There are few types of air conditioners: air source which uses the outdoor air to remove the heat from the system, and water source (typically found in high rises, custom homes, and some commercial applications) use water to remove the heat from the system. The main components located in the outdoor unit are the compressor and condensing coil. Efficiencies are rated by the SEER method, currently, 14 SEER is the minimum and 27 SEER represents some of the upper ends of efficiencies. Knowing the benefits of each type of system and what fits your needs the best is a specialty of ours!

Indoor Air Quality

Indoor air quality has become a very popular aspect of the HVAC industry. As its name implies the indoor air quality refers to the quality of air in your home or business. Since the air is circulated by the HVAC system it is in a good position to clean the air in your space. Items like filters, air purifiers and UV lights all contribute to improving the indoor air quality.

Comfort Controls

With improved technology your thermostat can now be controlled remotely. If you are away from your home for the day, or the season you can keep tabs on the indoor conditions from your mobile device. Many of the equipment manufacturers have communicating equipment; with these systems the comfort control can provide remote access, current weather, and self-diagnose problems that may affect your HVAC system. Most comfort controls have a programming feature so you can schedule a time and temperature for when you are away. We offer a full variety of comfort controls from simple basic to the highly rated Wi-Fi controls.

UV Lights
One portion of the IAQ aspect of your HVAC system is to keep the surfaces inside the air handler clean. As air passes through the air handler it can pick up biological growth that may be occurring on inside surfaces of the air handler or the coil. UV lights do not treat airborne contaminants; however, it does prevent biological growth from occurring on surfaces. If the surfaces are kept clean the IAQ improves. Air purifiers can be either active or passive, both offer benefits of keeping the air clean and free of contaminants. These purifiers can reduces airborne and surface microbials, bacteria, viruses, mold, smoke, odors, VOCs, allergens, dust, and particulate.

Air Handlers
The air handler is typically found inside the home or business. This is the piece of the system that circulates the air through the duct system, then the space. As mentioned in the IAQ description this piece of equipment where biological growth can occur and is one of the primary focuses of a preventative maintenance visit. Since the environment inside the air handler is typically cold, dark and damp it is good spot for biological growth. Air handlers are made in a few different varieties. The most efficient are variable speed air handlers, this feature allows the fan to be fine-tuned for airflow. Since airflow is critical to the performance of the HVAC system, the variable speed fan can improve efficiency and comfort. The main components in the air handler are the blower, evaporator coil and the electric heater. Knowing the benefits of each type of air handler and what fits your needs the best is a specialty of ours!
Heat Pumps
The heat pump is typically the outdoor unit. Compared to the Air Conditioner, what makes this piece of equipment different is the heat pump has the ability to provide mechanical cooling and heating. On a strait cool (or Air Conditioner) system the heat is provided from an electrical strip heat (or gas furnace when outside of our little slice of paradise), which is located in the air handler. Electric strip heating is not a very effective heater especially when compared to the heat pump system. Fortunately here in south Florida we do not need heat very much; however, if heat is important to your comfort you may consider a heat pump system. Efficiencies are rated by the SEER method, currently 14 SEER is the minimum and 24 SEER represents some of the upper end of efficiencies.
Upgraded Filters

Another aspect of IAQ is filtration. All air handlers have a basic filtration system. The air handler is the central location for all the air in your home or business to pass through. This makes it an ideal location to filter the air. Originally the air filter was designed to keep the evaporator coil clean, not to “clean the air.” In the past few years the filtration industry has grown to more and more efficient filters. Filters are rated with MERV (Minimum Efficiency Reporting Values), report a filter’s ability to capture larger particles between 0.3 and 10 microns system. Typically MERV 8 – 14 are used residentially. You may have also heard of HEPA filters when talking about air filtration. HEPA is a type of pleated mechanical air filter. It is an acronym for “high efficiency particulate air [filter]” (as defined by the U.S. Dept. of Energy). This type of air filter can theoretically remove 99.97% of dust, pollen, mold, bacteria, and any airborne particles with a size of 0.3 microns. HEPA is mostly used in commercial applications and medical facilities. There is a caution here; the more efficient the filter the less amount of air can pass through it. We must be careful not to restrict the airflow to the air handler by using highly efficient air filters. There are ways to work around this issue but we want to make sure the duct system can support highly efficient filters. Feel free to give us a call at 561.844.1004 if you have questions about which filters are best for your application.
