Air Conditioning

What You Should Know  (A/C Residential)

Today's best air conditioners use only a fraction of the energy to produce the same amount of cooling as air conditioners made in the mid 1970's. Even if your air conditioner is only 10 years old, you may save significantly on your cooling energy costs by replacing it with a newer, more efficient model. Both R22 and R410A systems may have the Energy Star® label. Equipment that displays the Energy Star® label must have a minimum seasonal energy efficiency ratio (SEER) of 13.0. The higher the SEER specification, the more efficient the equipment.

Another important thing a homeowner can do for the environment; regardless of the refrigerant used is a selected reputable dealer that employs service technicians who are EPA certified to handle refrigerants. Technicians often call this this certification "Section 608 certification," referring to the part of the Clean Air Act that requires minimizing releases of ozone depleting chemicals from HVAC equipment.

What You Should Know  (A/C Commercial)

As R22 is gradually phased out, non ozone depleting alternative refrigerants are being introduced. Under the Clean Air Act, EPA reviews alternatives to ozone depleting substances like R22 in order to evaluate their effects on human health and the environment. EPA has reviewed several of these alternatives to R22 and has compiled a list of substitutes that EPA has determined are acceptable. One of these substitutes is R410A, a blend of hydro fluorocarbons (HFC's), substances that do not contribute to depletion of the ozone layer, but like R22, contribute to global warning. R410A is manufactured and sold under various trade names, including GENETRON AZ20®, SUVA 410A®, and PURON®. EPA will continue to review new non ozone depleting refrigerants as they are developed.

Existing units using R22 can continue to be serviced with R22. There is no EPA requirement to change or convert R22 units for use with a non ozone depleting substitute refrigerant. In addition the new substitute refrigerants cannot be used without making some changes to system components. As a result, service technicians who repair leaks to the system may continue to charge R22 into the system as part of that repair but at a much higher cost.

The transition away from ozone depleting R22 to systems that rely on replacement refrigerants like R410A has required redesign of heat pump and air conditioning systems. New systems incorporate compressors and other components specifically designed for use at higher pressures with specific replacement refrigerants. With these significant product and production process changes, testing and training is a must. Consumers should be aware that dealers of systems that use substitute refrigerants should be schooled in installation and service techniques required for use of that substitute refrigerant.

A Common Sense Approach To Servicing Your System

Along with prohibiting the production of ozone depleting refrigerants, the Clean Air Act also mandates the use of common sense in handling refrigerants. By containing and using refrigerants responsibly that is, by recovering, recycling, and reclaiming, and by reducing leaks their ozone depletion and global warming consequences are minimized. The Clean Air Act outlines specific refrigerant containment and management practices for HVAC manufacturers, distributors, dealers and technicians. Properly installed home comfort systems rarely develop refrigerant leaks, and with proper servicing, a system using R22, R410A or another refrigerant will minimize its impact on the environment. While EPA does not mandate repairing or replacing small systems because of leaks, system leaks can not only harm the environment, but also result in increased maintenance costs.

More and more people are becoming familiar with ductless air conditioning because those already have them are getting the word out as to how economical, quiet and efficient they can be.

As the name suggests, no ductwork or air distribution system is required. Because of this, there are few places where these units cannot be installed.

In addition to older homes with hot water heat, these systems have been used to air condition large & small offices, motels, hotels, Board rooms, computer rooms, schools, hospitals & labs.

    Ductless systems are made up of four components.

  1. The condensing unit - located outdoors
  2. The indoor unit which can be wall or ceiling mounted
  3. Refrigerant piping and electrical cables connecting the 2 units together
  4. A wireless remote or wall mounted controller

Most units are available from 1-5 ton capacity and may be operated down to -10ºF ambient. Heat pump models offer low cost heating as well.

The combined losses in efficiency due to an oversized furnace and chimney liner is much more of a loss with today?s energy costs than ever before. Today?s heating contractor typically will size a furnace to no more than 10-15% higher than the actual heat loss of the home. Tradesman provides repair, maintenance, and installation services for a wide variety of furnaces and heating equipment.


To Repair or Replace

One of our comfort consultants can explain all of this in more detail if you wish, and will calculate a Payback Period to help you make a more informed decision. The physical life expectancy of a Furnace or Air Conditioner can often be longer than its economic life. You may also use the following link to help you calculate a true payback period on this investment. Future costs of fuel and energy will tend to go up more than down.


Replace Equipment

We will provide clean drop sheets to protect your flooring .It is however suggested that you remove any clutter from around the furnace and anything fragile that may be in the work area. Whether it's your home's first Central Air Conditioning system or a replacement of your heating or cooling system. Our crew will make every effort to complete the work in one day to minimise your inconvenience.

Environmental concerns for air quality have been known to us for decades, but only recently have we seriously begun to address the quality of indoor air, the air that we are exposed to the better part of our lives, the air in our homes. High efficient air-tight homes help reduce energy costs, but have a negative effect of reducing air changes, keeping higher concentrations of airborne contaminants trapped inside.
