Where Did Air Conditioning Come From?

Monday, August 31st, 2015

We’ve grown so accustomed to having air conditioned spaces that it can be hard to imagine not having access to the cool, dry air that keeps so many of us comfortable during the summer months. However, if it weren’t for the steadfast work of a young engineer in the early 1900s, who knows when people would have been able to enjoy whole home cooling? Following is an overview of how air conditioning first came into being. (more…)

Why Good Dehumidification in Your Home Is Important

Monday, August 17th, 2015

You may not realize this, but part of the reason air conditioning feels as good as it does is because your air conditioner removes both heat and humidity. If the humidity isn’t removed, you’ll end up with a home that is cold but clammy, and no one wants to feel like that. But comfort isn’t the only reason dehumidification is important, as the AC experts at Comfort Central, Inc., can tell you more about below. (more…)

However, when you call the cooling specialists at Comfort Central, Inc., you won’t have to keeping living with this kind of discomfort in your Brevard, NC home. (more…)

Is a Zone Control System Right for My Home?

Monday, April 27th, 2015

Homeowners interested in air conditioning options may have heard the term “zone control system” without quite realizing what it means. It’s an option for your air conditioner, designed to provide more control over the temperature of your home and lower your monthly bills in the process. Zone controls offer a lot of benefits, but they don’t fit every situation. Many Asheville, NC residents could do well with one, but before pulling the trigger on an installation, you need to ask “is a zone control system right for my home?” (more…)

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.

How a Thermostat Affects Your Air Conditioning

Wednesday, July 30th, 2014

It doesn’t take special training to know your thermostat is the instrument that tells your air conditioner to turn on and off. But, with recent technological advancements, today’s thermostats do much more than start or stop the cycling of your AC. Comfort Central, Inc. specializes in the installment, repair and replacement of thermostats, and we’ve seen first-hand how a new thermostat can positively affect air conditioning systems in Black Mountain, NC.

How Can a New Thermostat Affect Your AC?

A new thermostat has several benefits:

  • Energy efficiency – the precision of digital thermostats and the ability to program them make today’s thermostats much more energy efficient than thermostats from just a decade ago. Digital thermostats are precise, as opposed to slide or dial thermostats, and when you use a digital thermostat that is also programmable, you gain tremendous control over how, when and to what temperature you cool your home. Many times, this equates to the need for less operation of your AC and more efficient cooling, which can reduce your energy usage.
  • Ease of use – digital thermostats are easy to read and operate, and don’t need to be calibrated like mercury thermostats do.
  • Convenience – programmable thermostats allow you to set the cooling for a 7 day program you can loop, freeing you from the constant need to adjust it.

Reasons to Consider Upgrading Your Thermostat

  • Age – if your thermostat is more than 10 years old, you could be missing out on significant energy efficiency savings.
  • Malfunction – is your thermostat constantly malfunctioning? This can cause your air conditioner to cycle on and off inconsistently, which contributes to wear and tear.
  • Constant need for repair – have you needed multiple repairs on your thermostat? At some point, your repair costs may be equal to the cost of a new thermostat.

Why Use a Professional?

Your thermostat is the control center for your air conditioner. If a new thermostat is installed improperly, it can wreak havoc on your air conditioning system in Black Mountain. If you are ready to upgrade your thermostat, call Comfort Central, Inc., today and schedule an appointment with one of our installation experts.

What Does the Energy Star Sticker Mean?

Friday, June 13th, 2014

If you’re in the market for a new air conditioner, you may have noticed a little sticker on the side of certain models reading “Energy Star.” Clearly, it’s a selling point, but what does the Energy Star sticker mean? The short answer is that it’s a mark of quality courtesy of the EPA, denoting models that are more energy efficient and cost-effective than normal. For people looking into new air conditioning in Arden, NC, there are HVAC companies that can help you with the specifics of a decision. The Energy Star sticker is a quick “cheat sheet” to guide you in the right direction.

The Energy Star system was established by the EPA as a way of encouraging companies and consumers to invest in more efficient technology. In terms of air conditioners, that applies mostly to the SEER (Seasonal Energy Efficiency Ratio) rating. This rating is roughly derived from the amount of energy the air conditioner consumes versus the amount of energy it actually uses to cool your home. The higher the rating, the more energy goes into the air conditioner’s job instead of being wasted on inefficiency. The U.S. government mandated that all air conditioners produced in 2006 or later needed to have a SEER rating of at least 13, though units built before then that are still in operation don’t need to have a SEER rating that high.

For units with the Energy Star sticker, that number needs to be even higher. For single package systems, the unit needs a SEER rating of at least 14. For split systems, the number needs to be at least 14.5. You may be able to find a cheaper unit that doesn’t have the Energy Star sticker, but chances are it will end up costing you more in the long term due to higher monthly energy costs.

If you’re installing a new air conditioning in Arden, NC, we have the experts you need at Comfort Central, Inc. We can talk to you about what the Energy Star sticker means, and how that will factor into your decision to purchase a new unit. We have the skills and experience you need, so give us a call today!

Condenser Problems with Your Air Conditioner

Friday, May 16th, 2014

Central air conditioners are called “split systems” because they consist of two separate units, one housed indoors and the other outdoors. The outdoor unit of an AC is called the condenser because it is where the condensation stage of heat exchange happens: condensation occurs along the refrigerant coil and heat is released. The condenser also contains the compressor—the core of an air conditioner’s operation—where refrigerant is heated and put under pressure so it will move through the system.

When your AC’s condenser begins to experience trouble, you need to call for professional repairs as soon as you can. Don’t open up the cabinet and try to figure out the problem on your own: condensers are too intricate for amateur work. Instead, call our air conditioning repair technicians at Comfort Central, Inc. in Hendersonville, NC and let us put our experience to work for you.

Some common condenser problems you may encounter

Because the condenser is located outside, it can sometimes suffer from contamination due to debris that enters the cabinet. Gravel, leaves, even small branches from trees can become lodged in the condenser and damage the fan or other components. To help prevent this, make sure you keep the area around the condenser’s cabinet clear for at least a foot in all directions.

The blower fan in the condenser performs the important function of drawing outside air across the condenser coil and then exhausting the released heat out the top of the cabinet. The fan can encounter repair needs because of mechanical malfunctions, trouble with its motor, or electrical faults, leading to poor air circulation and a drop in the AC’s cooling power. Technicians will find what has caused the fan to lose power and repair it.

The compressor is the most vital component inside the condenser: if it stops working, the air conditioner cannot provide any cooling. A common problem that compressors encounter is stressful operation because of lack of lubrication or an excessive amount of dust.

If you start to notice a reduction in cooling power in your home, hear loud sounds from the condenser, or spot ice developing along the unit, don’t hesitate to call for repairs. Contact Comfort Central, Inc. and we will send one of our repair technicians out to you to solve the trouble with your air conditioning in Hendersonville, NC.

Hissing from My Air Conditioner: Is This Normal?

Friday, May 2nd, 2014

Anything with a motor is going to make noise, but we all know when we hear something that sounds “off.” When it comes to your air conditioning in Asheville, there are certain sounds that could mean something is going on; one of these is a hissing sound. We’ll discuss the possible origins of a hissing sound, but it’s always best to call a professional from Comfort Central, Inc. whenever you encounter a problem with your air conditioner.

Potential Cause #1: The Expansion Valve

One source of a hissing noise could be the expansion valve. During normal operation of your unit, the refrigerant circulates throughout the system, expanding into a high-pressure, hot gas, then cooling off and turning back into a low-pressure liquid. It completes this process through the expansion valve. In some outdoor units, this process produces a hissing sound at regular intervals that lasts several seconds. Typically, these noises are not cause for concern, but it’s always best to check with a specialist from Comfort Central, Inc.

Potential Cause #2: Internal Valve Leak

A second potential source of hissing may be from a leak in the internal valve. Typically you’ll hear a noise from the internal valve when your unit is shutting down. An internal valve leak hiss is a bit louder than that of an expansion valve, and if it continues without repair, it can start to sound like a trumpet. Valve repair and/or replacement is complex and should only be performed by a professional.

Potential Cause #3: The Compressor

The compressor is one of the key parts of your entire air conditioning system; as such, dealing with a compressor problem is a serious service. Different noises can indicate different problems within the compressor, but a hissing or screaming noise typically means that there is too much internal pressure inside the compressor. This can be a potentially dangerous situation and requires that you shut your system off immediately and contact a Comfort Central, Inc. professional to take a look at it.

Potential Cause #4: Vent Registers

If the hissing noise is coming from your vents or registers, there is probably not a mechanical issue with your system. An inspection by your Comfort Central, Inc. specialist can clarify any problems.

When in Doubt, Shut It Down and Call a Professional

If you suspect your AC system isn’t working properly, either based on a strange noise or issues with operation, shut it down and schedule an appointment with your Comfort Central, Inc. professional today. We will help you to enjoy outstanding air conditioning in Asheville. Give us a call today!

Qualities of Reverse Cycle Chillers

Friday, April 25th, 2014

Air conditioning in Hendersonville and other nearby towns used to be a very one-note affair. Each system was more or less the same and you didn’t have a lot of options as to which one you chose. That’s much different these days. Air conditioners come in a wide variety of styles and systems, allowing you to find the one that works best for your particular circumstances. In particular, the qualities of reverse cycle chillers offer intriguing options that could be perfect for your needs. They’re a type of heat pump – a system that provides both heating and air conditioning in one unit – that features a unique way of conditioning the air in your home or place of business.

Chillers are essentially air-source heat pumps, which facilitate a heat exchange with the surrounding air: pulling heat from it or venting heat into it to help with the cooling cycle. Chillers differ from other types of heat pumps because they are sized to handle the heating load rather than the cooling load. Furthermore, they don’ directly heat or cool the air the way normal heat pumps do. Instead, they heat or cool the water in a nearby tank, which will then heat or cool the air to be circulated in your home.

Reverse cycle chillers work well because they are extremely inexpensive to operate, and their durability means that they can last a long time. They’re also modular, which means that you can add more units as your needs increase – a particular concern for businesses and those operating commercial space – and because they largely rely on electricity for power, you can connect them to your existing power grid with few difficulties.

The qualities of reverse cycle chillers don’t make them a universal cure-all, but they can be quite attractive for those in the right circumstances. And the experts at Comfort Central, Inc. can help. We offer all kinds of air conditioning services in Hendersonville, including reverse cycle chillers, and we’d be happy to help you plan for and install the system that works best for you. Give us a call today to make an appointment. You’ll be glad you did!
