Coming Efficiency Changes for Air Conditioning Systems to Take Effect in 2015

Wednesday, August 27th, 2014

One of the most important specifications on an air conditioner is its “seasonal energy efficiency ratio,” or SEER. This number indicates how well the air conditioner converts electrical power into cooling power. The higher the SEER number, the less the air conditioner will cost to run over a cooling season.

However, higher SEER air conditioning systems tend to cost more upfront to install, so when you are considering having new installation of air conditioning in Asheville, NC, you may wish to have a lower SEER rating to match your current budget needs. Consult with HVAC professionals, like the people at Comfort Central, Inc., to help you make the best choice for your comfort and financial needs.

The New Regional Efficiency Standards

Effective January 1, 2015, the Department of Energy and the American Public Gas Associating will implement new Federal Regional Efficiency Standards. These standards will affect both air conditioners and heat pumps—both split and packaged systems—and are designed to ensure that more energy-efficient units are installed to help reduce the U.S. reliance on fossil fuels.

The standards differ depending on region; for North Carolina, the standard requires that all split system air conditioners (the standard central ACs for most homes) have SEER of 14 or greater. All ACs manufactured after December 31, 2014, must meet or exceed this new standard. However, manufacturers, distributors, and contractors have until June 30, 2016 (and 18-month period) to ship and install systems that do not meet the new standards, specifically the 13 SEER units that are still common. However, all these system must be manufactured before January 31, 2015.

What does this mean for you as a customer? If you already have an air conditioner with less than 14 SEER installed in your house, you won’t need to worry. The new standards do not restrict repair and maintenance work done for existing systems. You can still expect to receive the same quality service for your air conditioner that you always have, using the same refrigerant blend.

However, if you are planning a new installation for air conditioning in Asheville, NC, you will have to make some choices about how soon you wish to have the work done. Some customers prefer the lower cost of 13 SEER units, which can make an ideal match with their budget plans. If you think that you may wish to have a 13 SEER air conditioning system installed, then you should consider scheduling the work soon. You can take advantage of the new units that the Regional Efficiency Standards will still permit manufacturers to produce until January 1. Contact Comfort Central, Inc. today and ask us about taking care of your installation; we will identify the air conditioner that will work the best for you, and if a 13 SEER is the right choice, we can have it installed long before the new efficiency standards go into effect. We aim to deliver you the best comfort available.

Air Conditioning Repair Guide: The Problem with Dirty Coils

Wednesday, August 20th, 2014

There are two sets of coils in your air conditioning system: the condenser coils and the evaporator coils. Each set plays an important role in the heat release and cooling process. When something is wrong with the coils, it affects the refrigeration cycle, which can impact your whole system. The coils are intricate, and because refrigerant flows through them, it is important to hire trained professionals to handle any air conditioning repair in Arden, NC that involves your system’s coils. Comfort Central, Inc., technicians are here to help you with any AC repair need you may have, so don’t hesitate to call us.

What Are the Coils?

The coils in your air conditioning system are narrow, serpentine tubing made of copper covered by thin, metal fins. In the refrigerant cycle of your AC, the condenser coils release heat from hot, high-pressure gaseous refrigerant that flows into the condenser coils from the compressor. Conversely, when refrigerant flows into the evaporator coils, it is a cool, low-pressure gas that absorbs heat from your indoor air as provided by a return duct. The blower (fan) blows this warm air over the coils, where the heat is absorbed, and the resulting cool air is blown into your home through the ductwork.

How Does Dirt Affect Coils?

Through normal use, the coils in your air conditioner can become dirty. Dirt and dust cling to the coils, and if allowed to build, can create a layer that acts as insulation. Anything insulating the coils inhibits the correct operation of them: the condenser coils will not be able to properly release heat, and the evaporator coils will not be able to absorb heat. Once the refrigeration process is imbalanced, the entire operation of your system can be compromised.

Signs of Dirty Coils

There are a few key signs that you may have dirty coils:

  • Decrease in air flow
  • Increase in refrigerant pressure drop
  • Warm air blowing into your home
  • Strain on your compressor

Dirty coils can disrupt the operation of your air conditioner, or even lead to breakdown. The best way to keep your coils clean is with bi-annual maintenance. During any maintenance appointment, your coils are thoroughly inspected and cleaned of dust, dirt and debris. If you are seeing the signs that your coils may be dirty, call Comfort Central, Inc., for air conditioning repair in Arden, NC right away.

Why Do I Need a Specialist for Commercial HVAC Services?

Wednesday, August 13th, 2014

The commercial air conditioning system on your property helps to keep everyone feeling more comfortable. Since businesses succeed when clients, customers, employees, and/or tenants are comfortable, you know to call an air conditioning technician immediately when you need commercial HVAC services. What you may not know, however, is that only some technicians are qualified to install, repair, and maintain these sizable systems.

Residential air conditioning specialists may have plenty of experience dealing with home air conditioners. However, the differences between a residential unit and a commercial unit may be substantial, and a commercial technician may be unable to locate and repair problems quickly and accurately. The following list details three reasons you should always choose a specialist for commercial HVAC services.

  • Commercial air conditioners store all of the components in one cabinet. Commercial air conditioners are often large packaged units, meaning all of the components of a standard split system are combined into a single outdoor cabinet, generally located on the roof. A residential technician may be unfamiliar with the location of a particular part, spending more time repairing your system and leaving your building without an air conditioner for a longer time period.
  • Residential systems are much smaller than commercial systems. Commercial properties are much larger than most homes and, therefore, require a larger system. An inexperienced technician may be unsure of how to size a large AC before installation. Furthermore, someone who is not a specialist may not be able to calculate the proper amount of refrigerant needed for installation or when repairing a leak.
  • The needs of a business may change. Many packaged systems are modular, meaning they can be resized to meet the fluctuating needs of a business. The cooling capacity needed for a building is dependent upon the number of people who occupy it, the number of rooms and floors, and many other factors. An inexperienced technician may not know that a malfunctioning system needs to be modulated to fit the growing needs of a business.

At Comfort Central, Inc., we know you need a specialist with experience dealing with large packaged systems. Our technicians have the skills and experience necessary for a big job, whether it’s maintenance, repairs, installation, or replacement. For commercial HVAC services in Arden, NC, give us a call today!

How Air Conditioning Repair May Result from Poor Installation

Thursday, August 7th, 2014

The money you think you’ll save with an inexperienced installer—or even trying to take on the work yourself—will vanish under a mound of repair bills from numerous calls to technicians to keep the AC working.

Start off right with your new air conditioning and contact the trained staff at Comfort Central, Inc. It’s vital that you have professionals handle installing a new air conditioning system for your home. This is not only because amateur installation risks leaving you with a cooling system that doesn’t work correctly (or may not work at all), but also because shoddy installation can lead to numerous unnecessary repair issues cropping up. We handle installation for many types of ACs, including ductless mini splits and high velocity systems. And should you need air conditioning repair in Asheville, NC, we have you covered there as well.

Here are some of the repair problems that may arise due to amateur AC installation:

Ineffectual and damaged condenser

The condenser is the outside unit of an air conditioner, and it needs a proper foundation and placement in order to do its job effectively. Poor installation can place a condenser where it cannot vent correctly, and this will lead to poor cooling. Worse, the condenser can pull in debris from a crowded region around it, leading to damage to the fan, compressor, and other components. Professionals will make sure the condenser is installed in a safe, clear location.

Electrical troubles

Most repair issues with air conditioners originate from the electrical systems. If the AC is not correctly connected to the house’s power system, it can lead to the air conditioner constantly tripping circuits or unable to draw sufficient power to run.

Damage through the air ducts

A central air conditioner connects to the ductwork of a home. If it is badly connected, it will lead to air leaks that will not only lower the cooling ability and a drop in airflow, but also allow dust and debris to enter the ductwork and find their way into the AC cabinet, where they can damage motors and other components.

Wrong refrigerant charge

Part of installing an air conditioner is to fill it with the right amount (“charge”) of chemical refrigerant. Amateur installation could result in a charge that is either too high or too low, and both will lead to serious problems throughout the AC, such as frozen coils and an overheated compressor.

It’s easy to avoid all these troubles, some of which can be costly to repair, by going to professionals in for the work in the first place. Comfort Central, Inc. will help you avoid unnecessary air conditioning repair in Asheville, NC with professional installation from trained technicians. We will see that you have the right cooling system, installed fast and right the first time. Give us a call today to schedule your next AC service appointment.
