HVAC FAQs
How does an air conditioner work?
The majority of home and smaller commercial air conditioning systems circulate a compressed gas refrigerant in a closed “split” system to cool and condition inside air. The refrigerant has to be re-cooled and condensed, and outside air is the medium most often used to accomplish this. The term “split” simply means that components are divided into inside and outside portions as opposed to being located together in a “package” unit.
The refrigerants, widely recognized by the trademark “freon” (which is a registered trademark of the DuPont company for refrigerants), helps cool and dehumidify the inside air. In a “forced air” system, an internal blower circulates the conditioned air through ducts to the rooms where the cooler air is needed. The air ducts generally run either below the ceiling and inside the rooms (conditioned air) or in the attic (unconditioned air). An outside fan pulls air across the external parts of the system to cool and condense the refrigerant.
What are the benefits of air conditioning?
The benefits of air conditioning are to give a comfortable environment at work or at home throughout the seasons, Spring, Summer, Autumn and Winter. An Air Conditioning unit can have two functions – heating/cooling and humidity control. With an auto changeover switch on most new units, you set the temperature and the unit will cool or heat as required automatically.
What is the average life of a system?
Most systems have a lifetime of 10 to 15 years, with gas furnaces lasting 20-25 years. As your equipment gets older, its efficiency can decrease dramatically. You may notice that it gets noisier and needs repairs more often. If you live near bodies of water or the ocean, your system’s life expectancy may be drastically shortened due to the harsh environment. If your system is over 10 years old, you should have your system checked for maintenance or replacement.
Should I repair or replace my system?
There are five main questions that need to be considered when deciding to either replace or repair your heating and cooling system:
- How old is your system? If your system is more than ten years old, it may be wiser to invest in new, higher efficiency equipment, which could cut your energy costs by up to 40%.
- What is the efficiency level of your current system?
- What was the efficiency when the system was new? Unfortunately, replacing parts of your old system will not improve the efficiency. If the energy savings of using a higher efficiency system will cover all or part of the cost of investing in new equipment, you should seriously consider replacement of the old system.
- What is the overall condition of your system? If your system is in solid condition, it could be wiser to simply repair it. But if your system breaks down often, you should consider replacing it. Consider the 50% Rule.
- The 50% Rule- If the cost of repair vs. replacement of your system is less than half of its value and you haven’t been suffering the financial burden of frequent service calls to keep your system up and running, repair may be easier on your checkbook . Ask your technician to calculate the efficiency and energy usage of your system to help make a determination.
What goes into installing a new system?
Putting a new system in a home that has not had central air and heat before will require the installation of ductwork, insulation, refrigerant piping, electrical service, wiring, thermostat, condensate piping, flue piping, flue terminations, chimney liner, slabs, filter, driers, registers, grills, drain pans and evaporator coil. Beyond equipment, the most important component installed with a new system, however, is the duct-work.
Duct-work is composed of two parts, supply and return. Supply duct is attached to the outflow of the new system, delivering air to each zone in a home. The amount of air reaching each zone is determined by the size of supply duct-work connecting it to your system. Your dealer will help you determine the size of all the supply duct-work in your home.
The second part of the duct-work, the return duct, attaches to the inlet of the new system and draws air out of the spaces to be heated or cooled. Attached to the return duct is the filter. The filter should be placed as near to the furnace or air handler as possible. Duct-work can be either fiberglass or metal and must be properly sized in order to evenly distribute the proper amount of air to each room.
What makes up a ductless mini split system?
A ductless mini split system is composed of an indoor air handler/evaporator (fan coil), and outdoor condensing unit and an approximate 2.5-3″ conduit that accommodates the power (wiring), refrigerant line sets and a PVC condensate line (drain). s an indoor fan, referred to as the head, and an outdoor compressor unit. Many styles of air handler/evaporator (fan coil) are readily available depending upon your projects needs. Ductless units can be either 1:1 Single mini-split systems or Multi-split systems that can heat/cool multiple rooms.
How does a ductless split system work?
Ductless split systems can replace a traditional central ducted system or be used in addition to a central ducted system. It works in much the same way as a traditional air conditioner or heat pump, using an outdoor condensing unit, indoor air handler/evaporator (fan coil) with an outdoor condenser, attached to refrigerant line sets and a condensate drain line.
The condenser is installed outside the home or business typically on a code approved surface. The conduit is then run from the outdoor unit to the individual room within the structure that you choose, even an attic or garage. Depending upon the system design, the use of wall-mounted interior units, ceiling mounted units, recessed fa coils, floor mounted air handlers are then installed and secured in the appropriately desired spaces to control cooling, heating and humidity as needed and designed.
One or a series of indoor units and refrigeration lines are used to transfer the cooled air from the outdoor condenser to the indoor units of your choice. It works in reverse with heated air in the winter. Units can be placed in any rooms you like and because each unit is individual, you control the specific temperature in that room instead of needing to set one thermostat for the entire house. As a result, you save money by cooling or heating only the space you are using. One of its greatest advantages is TRUE ZONING!
When should I replace my heating system?
There are a few obvious signals that let you know when it’s time to upgrade your heating system. Frequent repairs, recent spikes in utility bills, and inconsistent temperatures in the home are a few warning signs that it’s time for a new heater. But if you’ve had the same heating system for twenty years or more, it would be a good idea to talk to an HVAC contractor about having it inspected to determine if it’s time for a heater replacement. Even if your old heater has worked without problems for years, a professional heating technician is trained to detect any possible operation or safety issues that are a direct indication that the system needs to be replaced. If you are concerned about your heating costs, you should talk to a heating professional about other options. Call us now to schedule your system’s check up!
