How Do Heat Pumps Heat So Efficiently?

Monday, November 12th, 2018

question-markThe quick answer? Because they use existing heat to heat your home, rather than generate new heat. That doesn’t make much sense at first, does it? If there were enough heat in the air outside to heat your home in the winter, couldn’t you just open the window to let that heat in? Well, the fact is that heat pumps do use existing heat in the air outside to warm up homes. There is a bit more to the process than that, though.

The “process” that we’re really referring to here is heat transfer, and that transfer of heat is the key to the heat pump’s efficiency. When properly installed and professionally maintained, a heat pump in Asheville, NC, can keep your home comfortable reliably while also cutting back on your heating costs. So, let’s take a closer look at what the heat pump is actually doing when it heats your home. That will help you to decide if the heat pump is the right heater for you.

How Long Will My Heating System Last?

Monday, December 21st, 2015

While we don’t use our heating systems here in Fletcher, NC, as much as other areas of the nation, it is necessary to have a reliable heater that delivers the warm air you need for the winter months. One question we hear often during an installation, replacement or annual maintenance appointment is, “how long can I expect my heater to last?” While there is no exact answer, we can give you average lifespans. However, it is important to note that average lifespans are based on properly maintaining your system and they aren’t set in stone. (more…)

The Risks of Amateur Heating Repairs

Tuesday, January 13th, 2015

So you’re trying to save a little money in the new year, when all of a sudden, an unexpected heating repair leaves you without any heat in the home. You may feel that calling a contractor is too much of a drain on your budget, so you look up guides and advice on the internet to try and diagnose and repair the problem yourself. Whether you’re setting out to attempt repairs on your own or you’re enlisting the help of a family member with little experience, it’s important to note that amateur heating repair in Asheville can risk your home’s safety and may have unsatisfactory results.

Safety

One reason to avoid amateur repairs and installation is the potential risk to your safety. Furnaces run via the natural gas line, which means that there is always a chance of gas leaks. While modern furnaces contain safety switches that keep gas from potentially entering your home, an untrained repair person may be unsure of how to monitor these features or how to make repairs in the safest manner possible.

Efficiency

If your heating repair is not completed using the proper methods, you may notice that your energy bills continue to go up. When one part of your heating system is not working properly, the other parts all have to work harder to compensate, which means that you end up paying a lot more every month. This may be true if your amateur repair person selected the wrong sized component or even if there are loose screws or small air leaks in the system.

Comfort

Finally, with amateur heating repairs you risk reducing your home comfort. A heating system that is not properly repaired is likely to perform poorly, giving off too little heat or reduced heating in certain areas of the home. A trained professional is able to test the system for any further problems and repair all parts of the unit that must be addressed for proper operation. If not, you risk a heating system that breaks down far sooner than its expected lifespan.

Advantages of a High Velocity Heating System

Wednesday, December 17th, 2014

Thanks to certain kinds of heating systems, not having traditional ductwork in your home is no longer an obstacle. Ductless systems and high velocity systems both offer heating and cooling, and do so without the need for traditional ductwork. While both ductless systems and high velocity systems use a heat pump to provide heating and cooling, each system works differently. Today we’re going to take a look at what a high velocity heating system in Hendersonville can offer you and your home.

What Is a High Velocity System?

A high velocity system is comprised of a heat pump, small air handler and flexible, narrow tubing that functions as ductwork because it is snaked through your walls and given an outlet by which to distribute the air. The condenser and compressor are housed in an outside unit, and the air handler can be placed in a closet or other small space; the air handler and outdoor unit are connected via the refrigerant line. The tubing, which is 2” in diameter, is installed into your home with little to no need for construction; the outlets for the tubing are the same width as the tubing.

The way a high velocity system heats and cools your home is via a method called aspiration. With aspiration, the air is blown into your living spaces at a high rate of speed – about 2,000 feet per second. This high rate of speed forces the air in the room to mix, making the room comfortable.

Benefits of a High Velocity System

So why should you consider the installation of a high velocity system? Here are some reasons to consider:

  • The system fits virtually any home – because of the flexible tubing, a high velocity system can fit with just about any home; they can be especially good systems for retro-fitting.
  • Very energy efficient – the high rate of the air allows the system to use about half the air flow of other forced-air systems; additionally, the heat pump only needs about 25% of the electricity of a standard air conditioning system to operate.
  • No more uneven heating – air currents are created in your living spaces due to the velocity of the incoming air from the system; this heats and cools your home very evenly.

What Is the Exhaust Flue in a Furnace For?

Wednesday, October 15th, 2014

Most people don’t ever think about their furnace’s exhaust flue. They check the pilot light, occasionally the air filter, but the flue is often forgotten. Whether or not you realize it, however, the exhaust flue fills a vital role in the operation of the furnace. Let’s look more closely at what the exhaust flue does. First, we’ll examine why it’s necessary in the first place.

Combustion Gases

No matter what kind of fuel your furnace burns, be it wood, oil, natural gas, propane, or something else entirely, it will produce more than just heat from the fuel it burns. There are several common fuel combustion byproducts produced by normal furnace operations. Virtually all of these byproducts are toxic, but some are far more dangerous than others. One of the most deadly is carbon monoxide. This gas is odorless, tasteless, and completely invisible to human senses. The side effects of heavy exposure to carbon monoxide include nausea, dizziness, unconsciousness, and death. All furnaces produce these combustion gases. If not for the exhaust flue, these deadly byproducts would become trapped in your home.

Exhaust Flue Operation

When a furnace burns fuel, the combustion byproducts rise through the heat exchanger to the exhaust flue. The flue then vents the gases outside where they can safely disperse. Occasionally, the flue may connect to a chimney. In most cases, however, the flue simply exits out the side of the house. Despite the simplicity of the flue, there are a number of things that could compromise its effectiveness.

Issues

The first issue you’re going to want to keep an eye out for is any kind of crack or leak in the flue. This can cause combustion gases to leak into your home. Next, make sure that your flue is inspected every year for blockages. Birds will occasionally build their nests in exhaust flues, especially if they are connected to chimneys. This will trap most of the combustion gases from your furnace in your home.

If you haven’t had your furnace inspected yet this year, call Comfort Central, Inc. We provide heating repair service throughout the entire Hendersonville area.

Causes for Your Heating Running Inefficiently

Monday, March 31st, 2014

It’s almost time to turn off the heat and turn your AC, and with that time comes a chance to address an inefficient heating system. Inefficiency can be easy to ignore in some cases, since your heating system will still work, but need more fuel to do its job. That means you can keep running your heater and paying the cost of your monthly bills, even though that cost may skyrocket throughout the winter. When the temperatures are cold, it can be very inconvenient to schedule a repair to handle such inefficiency. But now that spring is here, you shouldn’t have to waste any more money on a less than optimum heater.

Here are some of the causes for your heater running inefficiently, which a good repair technician can help you with:

A fair amount comes from simple dust and dirt building up over the course of time. Dust can increase friction on moving parts and force your heater to work harder than it should. Similarly, the burners can get clogged with gunk, preventing them from working or forcing them to work at a lower capacity than normal. All of that can interfere with your heater’s ability to do its job, costing it precious energy and increasing your bills in the bargain.

Reduced air flow forces the heater to work harder as well. In some cases, this can come from blockages in the system, particularly from a clogged air filter or something in the duct system. It can also come from problems with the fan motor, from bent or damage fan blades. Indeed, any loose component can be the cause of inefficient heating.

Repair services need to treat the causes of your heater running inefficiently, not just the symptoms. A regular maintenance visit can help do that: cleaning dirty parts, tightening loos components and generally helping the heater run as well as it can. For heating service in Asheville, NC, contact the experts at Comfort Central. Inc. We’ll get to the heart of the matter and help you cut those heating bills down next winter.

3 Reasons to Replace Your Furnace with a Heat Pump

Thursday, March 20th, 2014

Forced-air furnaces are a staple of many homes in the area, relying on burning gas pushed through a heat exchanger to warm your home. However, there are many different heating system options available, and you needn’t be bound to it if another type of heater will work better for you. Heat pumps, for instance, are an extremely popular choice, combining the functions of a heater and an air conditioner by using the same basic system of cycling refrigerant that normal air conditioners use.

Here are 3 reasons to replace your furnace with a heat pump:

  • Improved efficiency. Heat pumps don’t actually generate heat. They simply exchange it with the cycling refrigerant. Because of that, they don’t cost nearly as much to run as electric furnaces do, which can save you a great deal of money in monthly costs.
  • Versatility. Heat pumps work as both heaters and air conditioners, which means you can use them in the summer just as readily as you do in the winter. That saves you space and time, making for a more convenient way to keep your house comfortable no matter what the time of year.
  • Ease of service. Because you only have one system for heating and cooling, you should have it tuned up twice a year. However, having only one system means you will probably have fewer repair costs than if you had a separate furnace and air conditioner. You also will only need to do the same things to maintain your system year round, like changing the air filter and keeping the outdoor unit clear of debris. No need to learn how to maintain two separate systems!

Here in Hendersonville, NC, heating installation and repair issues can be handled by the professionals at Comfort Central Inc. We can give you plenty of reasons to replace your furnace with a heat pump, but we won’t do so unless the fit is right for you and your household will benefit from the switch. We have years of experience and our trained staff won’t rest until you are completely satisfied. Call us today to schedule a consultation. You’ll be glad you did!

Why Heating System Size Matters

Tuesday, March 4th, 2014

Installing a new heating system in Asheville is no smaller undertaking. Our North Carolina climate can undergo a number of extremes, and while we’re not as cold as some cities further north, you still need a heating system that can handle anything our winters can throw at you. That means you need to choose your unit carefully, with help from a trained professional and an eye on the best unit for you. The size of the heater plays a huge role in this, not so much the physical size as the amount of power it generates.

The reason sizing is so important is that a badly sized heater will cause a number of problems. If the power is too low, it won’t heat your home the way it should. If it the power is too high, it will heat the home too quickly, leading to rapid cycling on and off throughout the day. Heating systems use exponentially more energy when they turn on and off than they do while running. Rapid cycling only wastes unnecessary energy while increasing wear and tear on your unit. A heating unit should thus meet what we like to call the Goldilocks Rule: neither too small nor too large, but just right.

So how does one determine the right size? Part of it comes down to a straight measurement of square footage in your home. But other factors enter into the equation as well. For example, if you have a lot of insulation in your home, your heater won’t need to be as powerful as it would if you didn’t have as much insulation. Similarly, if you have large windows that face the west, you’re likely to get a lot of ambient sunlight in the afternoon, which will raise the temperature of the home accordingly. In that case, your heater won’t need to be quite as powerful as it would be otherwise. A professional contractor can do a heating load calculation of your home to determine what size heater will work for you.

Needless to say, such calculations can get quite complicated. That’s why you need a reliable heating company like Comfort Central, Inc. to help you find the right size heating system. We handle all kinds of issues with heating in Asheville, including installation, so give us a call today.

How Rust Appears in a Boiler

Monday, February 17th, 2014

Rust is a product of corrosion, the reaction of metal and water in the presence of oxygen. Rust should always be a concern to homeowners when it appears on appliances, and it usually calls for professional repairs.

Considering that boilers are primarily metal devices that circulate hot water, people are often surprised that they don’t rust more often. Boiler manufacturers design them to resist corrosion, principally through limiting the presence of oxygen within the system. Nonetheless, rust can occur on a boiler, and when it does, you’ll need trained professionals to find out why and fix the problem.

We’ll offer a short explanation for how rust can develop across your boiler. If you need help with this problem, call Comfort Central, Inc. and we will send our NATE-certified technicians to tend to your boiler in Hendersonville, NC.

Rust and your boiler

  • Stress cracking: Because boilers are constantly heating up and cooling down, there is a small amount of metal expansion that occurs along the tank. This can eventually cause cracks to develop that will allow oxygen inside. Dissolved oxygen in water is a prime promoter of rust. Along with removing the rust, repair technicians must fix the cracking.
  • Poor pH control: A high acid level inside a boiler will cause rust to develop. The main source of this problem is contamination in the boiler feedwater—the water that enters the tank. Although the water in your boiler runs in a closed system, outside compounds can enter through breaks in underground pipes. If new water introduced into your boiler after repairs isn’t properly treated, it can also have high pH levels.
  • Deposits: Boilers often pick up sediment in the water running through them, which falls to the bottom of the tank during heating. This sediment can allow in chemicals such as ammonia and sulfurous gases that promote corrosion. Regular tank flushing is necessary to prevent sediment build-up.

Avoid boiler rust with regular maintenance

The best way to keep a boiler from developing rust is to have a yearly check-up from an HVAC technician. Each year, the technician will check on the boiler’s operation and clean components that need it. Flushing out the tank will often help prevent the development of the conditions that will promote rust. Not only will maintenance help you avoid rust, it will make the boiler more efficient and catch other potential repairs.

Signs You Need Boiler Repair

Monday, January 27th, 2014

Many homes in Asheville, NC have boilers, and their efficient use of hot water is an inexpensive and effective way to heat your home. If something goes wrong with your boiler, you want it fixed quickly. The sooner you can have the problem fixed, the less you’ll need to worry about and the better the chances of avoiding a more serious repair in the future. If you need boiler service in Asheville, give Comfort Central, Inc. a call.

Here are some signs you need boiler repair:

  • Leaking water. Water leaks can spring up anywhere along the system, but look for it most in either the central unit, or along any fittings or seals in the pipes. Dripping water or puddles of water make the most obvious sign, though not every leak produces drips. (In those cases, you can check the water pressure levels to see if they’re dropping.) Leaks not only impact how well your system is able to heat, but can also cause damage to your home, so call for repair at the first sign of trouble.
  • Slow heating. If the boiler takes longer to heat up the home than you’d expect, there could be a problem with the burners. Or it may indicate that mineral deposits have built up in the boiler, forming an insulating layer between the water itself and the burners. Either way, it means that your boiler is undergoing more stress and strain than it should, and that the situation needs correcting before the problem becomes serious.
  • Noises. Strange noises often indicate mineral build-up in the boiler, as issues with water pressure. If could also indicate components under strain, struggling to do their job the way they should. If you boiler keeps making an unusual noise, be sure to make a note of where it seems to be coming from and how often it happens. This can help your heating technician more easily diagnose the issue.

If you spot signs that you need boiler repair, you shouldn’t delay. The longer you let a small problem fester, then better chance it has of turning into a big problem. Instead, contact the Asheville boiler repair professionals at Comfort Central, Inc. Give us a call today and let us show you what we can do!
