When summer arrives, a central air conditioning system offers welcome relief from rising outdoor temperatures and humidity. A properly designed and installed HVAC system can provide many years of quiet, economical comfort and also help improve indoor air quality. Homeowners with an air conditioner that is over eight years old may benefit from upgrading to a new energy-efficient model. In fact, replacing a 10 SEER air conditioner installed in the 1990s with a new 13 SEER system can save up to 30 percent on annual cooling costs. All air conditioners use the same basic technology to cool the indoor air. The refrigeration cycle begins when low-pressure refrigerant enters the compressor and leaves as a high-pressure gas. The gas flows into the condensing coil where the action of the fan dissipates heat and transforms the refrigerant into a high-pressure liquid. The indoor blower pulls warmer indoor air across the evaporator coil, and the heat energy is absorbed by the refrigerant. The resulting cooler air is then pushed back into the living air through the supply duct.

Air conditioning equipment is available in three primary configurations including: A professional AC installation always begins with proper system design. This includes running load calculations on the living area and sub-domains to determine the appropriate capacity requirements for the equipment. Poorly designed AC systems may not adequately cool every area of the building, and some rooms may remain hot and humid even while the system is operating. For this reason, contractors who do not run complete ACCA Manual J load calculations should be avoided. Selecting the right equipment to match the interior load is important, but the installation of a well-designed air distribution system is also a critical component in a fully optimized system. This includes sealing and double strapping all joints and connections to ensure that the integrity of the ductwork is not compromised by unnecessary bends or sagging. An impaired air distribution system can increase friction loss and reduce efficiency.

As a full-service air conditioning contractor, we provide ongoing support long after the AC installation is completed. This includes AC repair and maintenance services designed to keep your equipment operating at peak efficiency for many years to come. At Davis Air Conditioning & Heating, Inc. we understand the frustration associated with a malfunctioning air conditioner, especially when the outdoor temperature is extreme. install central ac unit homeWhen a unit breaks down, we quickly dispatch our courteous NATE certified technicians, who can accurately identify the cause of the failure. small indoor air conditioner coverMost common parts are stocked in our service vans, and we complete only those AC repairs necessary to restore the unit to full working order.monthly energy cost window ac unit

Fast credit for the futureThe FRM220-CH01M-AC is a single slot chassis for FRM220 compatible media converters. Casing has an integrated AC 90-240V power supply and comes with a standard IEC 3 pin power cord. It provides a serial RS-232 DB9 female port for local console connections. Such a casing offers ability to locally manage certain FRM220 series converters without the need of an FRM220-NMC management card and eliminates the separate AC adapter offered as default on all standalone FRM220 series fiber media converters.
