The Best Ways to Heat a Small Space

Wednesday, March 11th, 2015

If a part of your home is not hooked up to your central heating system, you cannot get much use out of this room during the cooler months. Some homeowners attempt to install point-of-use single room heaters to compensate for this, but these are highly inefficient and cannot heat up the whole room as effectively as a forced-air heating system can.

If you’ve recently added onto your home, or if there’s a small space in your home that goes unused when it’s cold outside, call the experts at Cool Air Mechanical. We can install a new efficient ductless or high velocity comfort system for you small space heating needs in Decatur, GA. These systems are described briefly below.

Ductless Heat Pump

A ductless heat pump has all of the same components as a traditional heat pump, which is an air conditioning and heating system combined. The only difference is that these units don’t need any ducts. Instead, an individual blower unit is mounted high up on the walls or suspended from the ceiling, and it connects to an outdoor compressor unit. You can use multiple indoor units to heat or cool a whole house, or you can have one indoor unit for a smaller space. These are highly efficient in both the heating and cooling season.

High Velocity Comfort Systems

High velocity comfort systems use very small ductwork to deliver cool or warm air from your central AC and heating systems to the various rooms of your home. This flexible ductwork can move air from your existing air handler into any new room addition or you can have an entirely new system installed in your home. The small size of the air handler and ductwork means it can fit into multiple different areas of the house. And the flexible ductwork won’t require any renovating. It’s designed to fit into most structures with ease, as it can snake through the walls, attic, basement, or even a closet. However, the small size means it should not occupy too much of the space you need for other purposes.

The experts at Cool Air Mechanical install and service ductless heat pumps and high velocity comfort systems. Call us today for superior air conditioning or heating service for your small (or large) space in Decatur, GA.

How a Faulty Thermostat Will Affect Your Heating in Dunwoody, GA

Wednesday, November 12th, 2014

The thermostat in your home is the instrument that controls when your heating system turns on and off. It may be a small device, but it is an important one, and when your thermostat malfunctions it can cause several kind of problems for your heating system in Dunwoody, GA. It can sometimes be difficult to diagnose a faulty thermostat, because the problems that develop can look like other issues. We’re going to outline below some of the more common effects a faulty thermostat can have on your heating system, but for all your heating repair needs, call the people you can count on: Cool Air Mechanical.

Problems Caused by a Faulty Thermostat

Here are some of the more common problems that can develop from faulty thermostats:

  • Short-cycling – short-cycling is the rapid turning on and off of your heating system. Short-cycling can cause overheating and damage, so it’s important to repair short-cycling as soon as possible. A couple of reasons why a thermostat can cause short-cycling is faulty wiring and too much dirt and dust on the instrumentation inside the thermostat.
  • No heat – there are a couple of ways a thermostat can cause your home to be without heat. If your thermostat uses batteries and the batteries die, this will cause the thermostat to turn off completely. Another problem can be the settings; make sure your thermostat hasn’t accidentally been switched to off or cooling. If you have a programmable thermostat, check to see if the program has been changed. Lastly, corroded or faulty wiring can result in no heat as the connection between the thermostat and the furnace may be damaged.
  • Reading the wrong temperature – older thermostats need to be calibrated properly in order to work correctly. If the calibration of your thermostat isn’t correct, it can misread the temperature inside your home, leading to incorrect temperature setting.

Your thermostat is the control center for your heating system in Dunwoody, GA. If you experience problems with your thermostat, or feel it may be time for a new one, call Cool Air Mechanical and schedule an appointment with one of our experts.

3 Myths About Heating in Roswell, GA

Wednesday, October 22nd, 2014

There are quite a few heating myths floating around, both on the internet and by word of mouth. The reason so many of these myths have survived is mostly linked to homeowners’ desires to save energy and money. When you’re trying to cut heating costs, you’ll probably be willing to try all sorts of things that may or may not make a difference. Here are our top 3 heating myths in Roswell, GA.

Myth: If You Set Your Thermostat Higher, Your House Will Heat Faster

Nope. This is 100% untrue. In actuality, the thermostat only has two settings for heat: on or off. When you set a target temperature for your thermostat, it compares that temperature to the current temperature in the room. If the current temperature is lower, it starts the heating system. Once the current temperature and target temperature match, the thermostat turns the heat off again. Setting a higher temperature will only make the heater work longer to get there, it won’t blow any hotter air than usual.

Myth: Closing Vents in Rooms You’re Not in Will Save Money on Heating

This is a very common one. People think that by closing the heating vent in rooms they aren’t using, the system only has to heat one or two rooms in the house. That means it doesn’t have to work as hard and will use less energy, right? Wrong. Just like above, heating systems like furnaces are actually quite simple in the way they operate. A heating unit is designed to provide the proper amount of heat for a certain sized space. Restricting that space can actually damage the heating unit.

Myth: You Don’t Need to Schedule System Maintenance Until There’s a Problem

This is possibly the most damaging of all. All heating systems, no matter what kind you have, require maintenance at least once a year to ensure that they are in top operating condition. Ignoring annual maintenance shortens the lifespan of your heating system and, in some extreme cases, can even be hazardous to your health by causing things like cracked heat exchangers.

If you would like to know more, call Cool Air Mechanical today. We specialize in heating repair service in the Roswell, GA area.

Why a Faulty Thermostat Calls for Heating Repair in Atlanta

Friday, March 21st, 2014

One of the more common problems that can affect a home heating system is trouble in the thermostat. Because a thermostat fault affects the general performance of a heater, it’s often hard to tell from the start that the thermostat is what’s causing the trouble. But with the assistance of professionals in heating repair in Atlanta, GA, you’ll get to the root of the problem quickly.

Here are some of the issues that a faulty thermostat can cause your heating. For all of these repair needs, you can contact Cool Air Mechanical for fast, professional service.

Heating problems from a faulty thermostat

  • Miscalibration: One of the most basic problems that can afflict a thermostat is a miscalibration that causes the thermostat to read the temperature either a few degrees too high or too low. When this occurs, the thermostat with begin to turn your heating on and off at the incorrect times, either overheating your home or leaving cold spots. You will need professionals to repair the thermostat so it records the correct temperature. It’s also possible for the thermostat to record “ghost readings” because of poor placement where the thermostat is near drafts or in the path of direct sunlight, in which case you’ll need technicians to relocate the thermostat.
  • The heater will not come on: If the heater doesn’t come on at all, the issue might be that the thermostat has lost its communication to the heating system. A set of wires inside a thermostat controls the functions of the heating system, and if the wires that control the fans or the heating elements lose their connection, the heater will not turn on at all. You will need to have a repair technician fix the wiring problem.
  • The heater will not turn off: Another thermostat wiring problem that can afflict a thermostat is a loss of the connection responsible for turning the heater or its fan off. If the heater runs continuously, it’s likely that the thermostat is at fault.

Repair or upgrade your thermostat

Thermostats have increased immensely in complexity over the last twenty years, so they require trained technicians to repair them when they develop faults. If your thermostat starts to malfunction, you may consider replacing it with a newer model instead of going with a standard repair; recent advances in thermostat technology can help you receive even more efficient and comfortable performance from your heating system.

Call Cool Air Mechanical to talk to us about thermostat heating repair in Atlanta, GA or to inquire about making an upgrade to your current thermostat. If you need repairs right away, we have 24/7 service available.

Will a High Efficiency Furnace Work in My Home?

Friday, January 24th, 2014

Furnaces have been around for a long time, and they have gotten more sophisticated and more efficient over the years. Furnaces now score high AFUE (annual fuel utilization efficiency) ratings and are some of the most efficient types of heating systems available. Special high-efficiency gas furnaces can score AFUE ratings of up to 98%, which means they consume 98% of the gas they use and convert it to heat, losing only 2% of it. High-efficiency furnaces achieve this feat through a second heat exchanger, which takes the water vapor from the first exchanger and condenses it to provide additional heat and reduce waste.

This sounds like such a good idea for home heating that you’re probably wondering if there’s a catch. Will a high-efficiency furnace work in your home? The answer is: “probably.” But it’s best if you consult with experts like those at Cool Air Mechanical for advice about the Atlanta, GA furnace installation that will work best for your home and your budget.

The main issue to consider with a high-efficiency furnace is that it vents differently than a standard furnace. If you are replacing an older furnace, your flue liner and other components of the ventilation system may no longer work with a high-efficiency model. This doesn’t mean you can’t have one installed, but you will need to invest in upgrades on the flue liner and the other components.

The other factor to consider is pricing. A high-efficiency furnace provides savings on your heating bills, but they cost more upfront to install. You should consult with your installer about how the high-efficiency furnace will affect your budget in the future, and determine if it is indeed the best long-term value.

Keep in mind that the fuel-efficiency of other furnaces is still quite high, even if they cannot match that of a high-efficiency model. You have many choices for your Atlanta, GA furnace installation, and with a trained expert helping you select and then install the right model, you should end up with a furnace that fits your comfort and budget requirements.

Common Furnace Repairs

Monday, January 13th, 2014

For your comfort during an Atlanta winter (which, although mild, can still offer some unpleasant surprises), a furnace is an excellent heating system. Given the right care, furnaces can last for many years, often besting heat pumps for longevity.

But furnaces are mechanical systems, and that means you will probably run into repairs at one time or another. It’s important that you call experts to handle the work, since trying to repair a furnace on your own—especially a natural gas furnace—is potentially hazardous. Cool Air Mechanical can take care of the repairs for your Atlanta, GA heating: 24 hours a day, 7 days a week.

Common Furnace Repairs

  • Cleaning dirty burners: The burner is where the jets ignite to create the combustion gas for a natural gas furnace. If the burner develops a layer of grime or corrosion, it can prevent the jets from drawing enough oxygen to ignite. If your furnace uses a pilot light instead of an electric ignition, the pilot light could also go out. Technicians will need to detach the burner unit in order to clean it.
  • Replacing burnt-out heating elements: For electric furnaces, the most common malfunction occurs with the heating elements, which are the sets of electric coils that heat up to warm the air. These elements can burn out and cause a loss of heating power. Technicians will need to replace them with new units.

Don’t wait to call for repairs; furnace issues need attention right away before they become worse and lead to a breakdown, or possibly a safety issue. You should also enroll in a regular maintenance program with an HVAC contractor so your furnace will receive the annual visits necessary to keep it running at top efficiency and effectiveness.

Cool Air Mechanical can deliver the quality work on your heating in Atlanta, GA that will make sure you always spend a comfortable winter.

Furnace Noises That May Warn of Repair Needs

Monday, January 6th, 2014

The sooner a qualified technician can see to a problem with your heating system, the easier and less expensive the repair is likely to be. Noises, in particular, often signal a furnace in need of repair. Any noise that’s out of the ordinary – that is, any noise that doesn’t sound like a normal part of the furnace’s functioning – probably merits an inspection from a qualified technician. Here’s a brief list of some specific furnace noises that may warn of repair needs.

  • Rumbling. Dirty burners or burners that have suffered damage can create a low rumbling sound when the heater starts up. If your heater has a pilot light, it might make a rumbling sound when the light isn’t properly adjusted. Neither problem is critical, but they can result in more significant issues if they are not treated.
  • Rattling noises. Loose screws and other detritus might rattle around in your furnace when it turns on. Again, this isn’t a problem in and of itself, but if you don’t address it, the loose object could damage a more vital part of the system.
  • Grinding noises. An overloaded motor may create a grinding noise, as can a fan that is twisted and rubbing up against another component. Problematic bearings may create these noises as well.
  • Booming noises. If gas builds up before being lit, it may create a booming noise when your furnace starts up. This can seriously damage the components and may present a safety hazard to boot. If you notice this problem, its best to call for repairs right away.
  • Clicking. Leaky gas valves can sometimes make clicking noises. Leaking gas is a serious safety hazard; if you hear clicking, then turn off the gas to your home and call in an expert immediately.

If you hear any furnace noises that may warn of repair needs, then call Cool Air Mechanical to help. When it comes to heating repair, Atlanta GA residents can rest easy in the hands of our trained technicians. We can hunt down the source of the problem quickly and get your heater running again as efficiently as possible. Pick up the phone and give us a call today!

What You Need to Know about Furnace Efficiency Ratings

Monday, December 2nd, 2013

If you are currently shopping for a furnace for your home, you need to know about how the efficiency of modern furnaces is rated. Efficiency is not the only factor in picking out a furnace—you also need to consider the availability of fuel, the heater’s effectiveness and size—but it is an important factor. An efficient heater can save you large amounts off your heating bills every year.

In this post, we’ll give you information about the principle efficiency rating used for furnaces, AFUE. This knowledge will help you narrow down your choices. However, this is only the beginning of understanding which heater will work for your home. To make the best choice possible, consult with experts like those at Cool Air Mechanical. We have years of experience with installation and furnace repair in Atlanta, GA.

AFUE: Annual Fuel Utilization Efficiency

The initials AFUE stand for “annual fuel utilization efficiency.” This is the universal rating used to measure the efficiency of furnaces. It is expressed as a percentage, which represents how completely the furnace converts fuel into heat, as measured over a year. The higher the percentage, the more efficient the furnace. A furnace with an AFUE rating of 90% produces 90 BTUs (British Thermal Units) of heat for every 100 units of fuel it burns. This means it wastes only 10% of the fuel available.

For a useful benchmark, the AFUE rating of conventional firewood is 45%-55%. Boilers and furnaces from around 50 years ago had ratings usually in the 60s. Currently, the U.S. Department of Energy requires that all furnaces sold in the country must have a minimum AFUE of 78%—and most score much higher than that. A high-efficiency gas-powered furnace can have an AFUE of close to 96%, making it one of the most fuel-efficient systems on the market. Most furnaces will fall in the upper 80s range.

Although a high-efficiency furnace will save you money on your heating bills, they also tend to cost more initially to purchase. Also keep in mind that AFUE does not take into account heat lost from your house, only the heat lost during the furnace’s conversion of fuel to heat. You can have the highest efficiency furnace ever manufactured but see little difference on your bills if your home does not effectively trap the heat.

When you’re ready for the installation of a new furnace in your home, consult with an HVAC technician to go over your options. Perhaps a lower-efficiency furnace will suit your budget and heating needs better than a model with an AFUE of 96%. The technician will help you balance the various criteria and guide you toward the heating option that will suit you best.

Whenever you need Atlanta, GA furnace repair or installation, contact Cool Air Mechanical.

Is the Air Handler in Your Heating System Damaged?

Monday, November 25th, 2013

The air handler is a fancy way of saying a blower or a fan mechanism that helps circulate air through your duct system and into your home. They’re usually connected to (or a part of) heat pumps and similar devices, which need them to operate in conjunction with an existing duct system.  Is the air handler in your heating system damaged? Here are a few signs that you might have an issue.

The easiest way to tell if your air handler is damaged is to monitor the flow of air through your ducts. If the air flow is reduced or nonexistent, then there’s a problem. Reduced air flow can come from damaged or bent fan blades, from blockage somewhere in the system, or from a motor that isn’t performing as well as it should. If the air flow is cut off entirely, then the fan motor may be overloaded, resulting in an automatic shut-off. The fan belt may have snapped or the fan itself may be blocked, preventing it from running at all.

Another telltale sign of damage is an odd or unusual noise coming from the air handler. It might be a buzzing or an arcing, suggesting a malfunctioning piece of electronics. It much also sound like a grating, particularly if the fan is misaligned and rubbing against other components. Any unusual sound is cause for concern.

If you think the air handler in your heating system is damaged, shut it down and call in a trained technician immediately. When it comes to heating repair in Atlanta, homeowners can count on the experts at Cool Air Mechanical. We handle problems with air handlers, so don’t hesitate to give us a call today!

Atlanta Heating Tip: How to Scale Back Heating Costs

Monday, November 4th, 2013

Winter in Atlanta can be quite beautiful, and even pleasant. But you will still need to have a dependable heating system in your home to get the most out of the season. When you turn your heater on for the first time during the colder weather, you can expect a rise in your power bills; quality heating can add up fast.

However, there are steps you can take to keep those costs from rising through the roof (one of which involves sealing up your roof, by the way). You don’t have to make huge sacrifices to your comfort to get excellent heating in Atlanta, GA. We have some tips that will help you keep those bills in check through the winter.

For more help with heating, such as repairs, maintenance, and installation, call our specialists at Cool Air Mechanical today.

3 ways to reduce your heating costs

1. Find an energy-saving thermostat level. Just because you can turn your thermostat up to tropical temperatures doesn’t mean you should. The U.S. Department of Energy estimates that lowering your thermostat by 6° to 10° for 8 hours a day can mean an 18% reduction in your energy costs. The ideal temperature during the day is 68°F (with an extra layer of clothing), and you can put it even lower when you are asleep. A programmable thermostat will help tremendously with monitoring this.

2. Properly insulate your house. If your home has too many spots where heat can escape, your heater will have to work overtime to compensate. Make certain to have windows caulked (or storm windows put in) and weather stripping placed around outside doors. Check that your insulation isn’t deteriorating, especially in the attic; because heat rises, the attic is the main place it will escape from your house. Think of insulating the attic as putting a thick wool cap on your head when you go outside.

3. Keep your heater in good shape with a maintenance check-up. Trouble in your heating system might be at fault for higher bills. A heater that is wearing down because it hasn’t received regular maintenance will drain extra power. Schedule professional maintenance once a year—preferably during the fall—and you’ll have a more efficient and cost-friendly heater.

If you want cozy heating in Atlanta, GA this winter without bills that make you panic, trust to the services of Cool Air Mechanical. We will help you get the best from your heating system.
