How to Choose Your Air Conditioning Specialist?

What should I look for when selecting an air conditioning contractor?  Since the climate control system you install is only as good as the contractor who installs it, choosing a qualified HVAC contractor is essential to having a home or building that is comfortable in all conditions and will last a long time. Skilled workers will determine the outcome of any major HVAC project, whether that is a completely new install, replacement of existing equipment, or upgrading ductwork and related systems. The best contractors have many years of experience in installing multiple kinds of heating, cooling and ventilation systems.

Furnace Estimate

So you need a new air conditioner and are trying to decide whether or not to try and save some money by having the new unit installed without a detailed analysis of your home's or business's actual cooling needs. This technique is quite common in many areas and many contractors don't see any problem with this method; however if you are looking for improved performance or efficiency, a professional installer should be able to assess your requirements and recommend the best approach before proceeding.

A C and Heating Repair

Air conditioning is an essential part of any house's climate control.  If the installation is done improperly then there is a chance the system will be too small to be adequate, or too large to be efficient.  When in doubt, seeking a professional's help is always advisable.

Three Types of HVAC Condensers

Gas Heating System Service A condenser is a device that is used to liquefy gas by cooling it. In HVAC equipment, hot discharge gas (refrigerant vapor) from the compressor enters the condenser coils at the top and is condensed, drains out of the condenser to a receiver located near the bottom. The condenser coil is located along with the compressor and controlling devices in the condensing unit. In a remote or split system air conditioning installation, the condensing unit is located outdoors. Condensers are available in a variety of sizes and designs that include plain tube, finned tube and plate type, series-pass and parallel pass units.Condensers are classified by their cooling method. The three main types are broken down to: Air-cooled condensers Combined air and water-cooled condensers Water-cooled condensers Air-Cooled CondensersAn air-cooled condenser consists of a coil of ample surface that air is blown by a fan or induced by natural draft. This type of condenser is universally used in small capacity refrigerating units. Mostly designed for residential or small office air conditioners.Air-chilled condensers should be kept from free from dirt, lint and other foreign materials because they tend to reduce the airflow around the tubes and fins if they are allowed to accumulate just like evaporators.Combined Air- and Water-cooled CondensersThis type of condenser is also know as an evaporative condenser and consists of a coil cooled by water sprayed from above and then cold air enters from the bottom and is blown across the coils. As water evaporates from the coil it creates a cooling effect that condenses the refrigerant within the coil. The refrigerant gas in the coil is hot which changed to the liquid state by combining the sprayed water and the large column of moving air supplied by the fan. The water that does not evaporate is recirculated by means of a pump.Water-Cooled CondensersA water-cooled condenser is similar to a steam surface condenser in that cooling is accomplished by water alone that circulates through tubes or coils enclosed in a shell. IN a water-cooled condenser the refrigerant circulates through the annular space between the tubes or coils. Because of its construction, a water-cooled condenser is also referred to as a double-pipe condenser. Because an evaporative condenser is not wasteful of water, large compressor installations are possible in areas where water is scarce. Tests have shown that the amount of water required will not exceed the.03 gpm per ton of refrigeration. This is one of the eco-friendly reasons to use this type of condenser. Evaporative condensers also eliminate water water disposal problems and provide the most economical means of cooling refrigerant gases of standard air conditioners.
