Should I Schedule Heating Repair in Sandy Springs if a Few Rooms are Cold?

Monday, September 30th, 2013

For centuries, fireplaces and coal stoves kept humans warm enough to survive harsh winters. But they did a poor job of spreading heat throughout a living space. People had to stay near the fire to get the best heat. Modern central heating systems solved this problem: using networks of ducts and pipes, they distribute cozy warmth all through a home.

So if a few rooms in your house start feeling chillier than normal, your heater could be sending up a signal flare that something is wrong. Does your heater need repair? It might—the trouble could range from something you can remedy in a few minutes, all the way to age issues with your system that could require new installation. Let’s look at some of the possibilities.

The simplest reasons for uneven heating are blocked vents, open windows, or an improperly set thermostat. If you use a furnace (likely in older Georgia homes), check room vents to see that they are open and that no furniture has been moved to block them. Make certain all windows are shut tight; even a small draft can drain the heat right from a room. See that the thermostat is set to “heat” and at the right temperature.

A more serious trouble that can turn rooms cold—but doesn’t require repairs on your heating system—is poor insulation. The icy rooms might not have enough insulation to keep heat trapped. Add weather stripping around doors and caulk windows if you haven’t already, and look into getting improved insulation in the walls.

If you exhaust these possibilities, then your heater may indeed need professional repairs. Broken ducts are a primary cause for leaking heat, and will require sealing. If you use zone heating, then one of the multiple thermostats may have a malfunction. If your heater is an older one—perhaps inherited with your home—then the uneven heating might be an early warning that the system is too aged and worn to do its job. Replacing it may be the most cost-effective route.

If you can’t determine the reason for the temperature change, then summon a heating specialist to hunt down the cause. A trained HVAC technician, such as the ones who work for Cool Air Mechanical, will know the best way to restore your home to its top heating ability. Whether you need a new installation or a simple heating repair in Sandy Springs, GA, look to the expertise of Cool Air Mechanical.

High Humidity and Heating in Atlanta

Tuesday, September 24th, 2013

Heating in Atlanta usually comes second in consideration to humidity. Our Georgia climate is always sultry, and that can do far more to impact our home comfort levels than mere cool weather. A heating system should be able to address the issue as effectively as it controls the temperature in your home. Here are some useful specifics concerning humidity levels and heating in Atlanta.

The humidity inside your home goes hand in hand with your comfort levels. The higher the humidity, the more your body will sweat, and the warmer you will feel. To maintain adequate comfort levels, you want a relative indoor humidity level to be somewhere between 20% and 50%. (It may seem natural to want higher humidity levels in the winter, but this isn’t always the case. When the temperature falls outside, high humidity inside can create condensation in your walls and on your windows, damaging components in the home.)

The heater is designed to affect temperature, not humidity, but in the process of doing its job, it may impact the levels of moisture in the air, particularly if you use a forced air heater. A furnace might dry out the air in your home, in which case you might need to install a humidifier to keep you comfortable throughout the winter months.

You can aid in this process by sealing any leaks around windows and doors, then scheduling a maintenance call from a qualified professional to give your furnace a thorough look. When dealing with humidity levels and heating in Atlanta, it pays to contact Cool Air Mechanical. As a local company, we understand the needs of local homeowners, and our services are undertaken with the highest levels of dedication and professionalism.

3 Common Problems Requiring Commercial HVAC Repair in Atlanta, GA

Monday, September 16th, 2013

Commercial HVAC units run according to the same principles as home heating and air conditioning systems, though they must often shoulder a heavier load. During the summer, you can ease the burden on your AC system by running the fan or opening the windows instead of using the AC when the sun goes down. However, that isn’t possbile with most commercial buildings. An office or retail business needs reliable air conditioning in order to function; otherwise, customers will stay home and employees will be miserable until you can arrange for proper commercial HVAC repair. Atlanta, GA compounds the issue with its hot humid summers. When issues arise, you can’t let them wait in the Georgia heat without causing significant damage to your business. Here are 3 common problems requiring commercial HVAC repair services.

  • Dirty components. Often, commercial HVAC components are located outdoors (usually on the roof with full exposure to the elements). When they get dirty or dusty, it can seriously interfere with the unit’s ability to function. For example, dust on the coils prevents the cooling process from working as it should, causing ice to form on the surface and reducing the amount of cool air going into the building. On a similar note, the drain line can become clogged with debris and build-up, creating stagnant water that could overflow and damage other components in the HVAC system.
  • Electrical issues. Most commercial HVAC systems require electricity to function, and problems can arise when electrical components break down. Worn contacts can result in arcing, or may shut down electrical power completely. Similarly, an overloaded component may trigger the circuit breaker connected to the HVAC system. (Some components may have individual shut-off switches, designed to cut power to the unit before any other parts of the system are damaged.)
  • Refrigerant leaks. Refrigerants are the gaseous chemicals that circulate through the AC unit, making air conditioning possible. When leaks develop in the lines, they can cause all kinds of problems, from an overheated compressor to ice forming on the evaporator coils. A trained technician can identify and seal the leak before recharging refrigerant levels.

If you experience any of these issues, you want to contact someone who knows the specifics of commercial HVAC repair in Atlanta. Call Cool Air Mechanical today to set up an appointment.

Atlanta Air Conditioning Guide: What Is in My Outdoor Unit?

Monday, September 9th, 2013

If you’ve spent any time walking around outside your home during a beautiful summer day, you’ve probably at some point wondered what exactly is in the outdoor unit of your air conditioner. Here is a list of the most crucial components contained in your outdoor unit—also called the condenser—and what they do to keep your air conditioner working.

  • The Compressor: This cylindrical device is what moves the refrigerant around your air conditioning system. It’s a pump that does quite literally what its name says: compressing the refrigerant, changing it into a highly pressurized hot gas that will move into the condenser coils.
  • The Condenser Coil: This is where the heat exchange takes place. The refrigerant heated from the compressor moves through this coil, where the heat is released to the outside.
  • The Fan: The fan does the job of  blowing air over the condenser coil, allowing it to dissipate heat to the outside. As the hot gas begins to cool down (condense) and turn into a liquid, it releases heat that the fan pushes to the outdoors. The liquid refrigerant now moves toward the indoor unit.

An air conditioner doesn’t just create cool air out of nothing and blow it into your home. It uses refrigerant to absorb the heat from the air inside your home and move it to the outside. The outdoor unit takes care of the job of removing that heat through the actions of the compressor, the condenser coils, and the fan. All of these components need to be in the best condition for your air conditioner to work effectively and to offer you a comfortable and pleasant living space.

The experts at Cool Air Mechanical have years of experience with air conditioning in Atlanta, and can take care of your needs if something goes wrong with your air conditioner’s outdoor unit. Our trained technicians are also available to perform preventive maintenance on your AC that will keep you from having to do more costly repairs later on. Call us today to schedule service!

Happy Labor Day!

Monday, September 2nd, 2013

On the first Monday of every September, we celebrate Labor Day in honor of workers everywhere who strive to make our local community and country great. We enjoy the holiday like any other business as a time for BBQ, hanging out with friends and family, and celebrating the end of summer. It also means the start of the NFL and college football seasons.

The origins of Labor Day are disputed, as is the case with many other holidays. Some cite Matthew Maguire, the machinist and secretary of the Central Labor Union of New York, while others cite Peter J. McGuire of the American Federation of Labor. Whomever the original founder, by 1894, the holiday had become widely recognized and was designated a federal holiday by Congress and President Grover Cleveland immediately following the Pullman Strike. This strike pitted US Marshals and US Military against employees of Pullman Palace Car Company outside Chicago, as workers sought to protest wage cuts and the firing of union representatives. At the time, the holiday was a way of repairing ties with workers and recognizing the importance of their contributions.

Today, we see Labor Day as an opportunity to recognize all the people who work hard to contribute to our county. Thank you, and Happy Labor Day from all of us!
