The changing seasons take a toll on your HVAC equipment. Unfortunately, it always seems that your aging furnace gives up in the middle of a cold snap and your AC unit sputters out during the hottest day of summer. These events are more than an annoyance: they can quickly turn into emergencies when your home reaches extreme temperatures. That's when it's time to call in your local ARS®/Rescue Rooter® HVAC specialist, who has the training to get to the root of any heating, ventilation or air conditioning problem quickly.
Engineers have pointed out some areas where efficiency of the existing hardware could be improved. For example, the fan blades used to move the air are usually stamped from sheet metal, an economical method of manufacture, but as a result they are not aerodynamically efficient. A well-designed blade could reduce electrical power required to move the air by a third.[25]

"I recently reached out to 5 STAR HVAC for an estimate/quote to install a new 4 ton furnace for my 2 story home. Thanks to Yelpers and the wonderful reviews for 5 Star, I now have a new go to company for my A/C and Heater needs! Not only was the estimate very reasonable, but the Technician "Jose" was very professional and gave great advice and service options for me."
Groups of DDC controllers, networked or not, form a layer of system themselves. This "subsystem" is vital to the performance and basic operation of the overall HVAC system. The DDC system is the "brain" of the HVAC system. It dictates the position of every damper and valve in a system. It determines which fans, pumps, and chiller run and at what speed or capacity. With this configurable intelligency in this "brain", we are moving to the concept of building automation.[1]

If the condenser coils are clogged, the compressor can overheat and shut down. You’ll experience intermittent periods of minimal cooling, followed by no cooling. Even if you’re “sure” the condenser coils are clean, clean them again. Turn off the power. Flip the air conditioning service and furnace circuit breakers in your main electrical panel to the “Off” position. Next, turn off the power switch right at the furnace or air handler. Then yank the disconnect block (Photo 1) and clean the condenser coils (Photo 2). If the air conditioning service still doesn’t work properly after you’ve cleaned the condenser coils, installed a new filter and opened all the supply vents, proceed with the following repairs.
When we’re in a customer’s home, we’re always on the lookout for things we can do to help them out and put a smile on their face.

Because an air conditioner moves heat between the indoor coil and the outdoor coil, both must be kept clean. This means that, in addition to replacing the air filter at the evaporator coil, it is also necessary to regularly clean the condenser coil. Failure to keep the condenser clean will eventually result in harm to the compressor, because the condenser coil is responsible for discharging both the indoor heat (as picked up by the evaporator) and the heat generated by the electric motor driving the compressor.

Heaters exist for various types of fuel, including solid fuels, liquids, and gases. Another type of heat source is electricity, normally heating ribbons composed of high resistance wire (see Nichrome). This principle is also used for baseboard heaters and portable heaters. Electrical heaters are often used as backup or supplemental heat for heat pump systems.

A dehumidifier is an air-conditioner-like device that controls the humidity of a room or building. It is often employed in basements which have a higher relative humidity because of their lower temperature (and propensity for damp floors and walls). In food retailing establishments, large open chiller cabinets are highly effective at dehumidifying the internal air. Conversely, a humidifier increases the humidity of a building.

A contactor is a $25 mechanical relay that uses low-voltage power from the thermostat to switch 220-volt high-amperage current to the compressor and condenser fan. AC contactors can wear out and are at the top of the list of common air conditioning service failures. Even if your contactor is working, it pays to replace it every five years or so. Unscrew the old contactor before removing the wires. Then move the wires to the new unit (photo 6).

As an Atlanta resident, you’re well aware that the weather in our area can go through extremes of both hot and cold throughout the year, taxing your heating and cooling system to its limits. You’ll likely encounter the need for repair or replacement at some point. If you need HVAC installation, HVAC maintenance, or HVAC service and repair, R.S. Andrews is the most trusted name in Atlanta.
Eventually, every homeowner experiences a malfunction in their heating unit. It’s a cold morning and you hike the thermostat up like you usually do to take the chill off, but you get no response. You don’t hear the system firing up or feel the radiators or air vents producing any heat. You hope it’s just a quick fix, like a clogged filter or a tripped circuit breaker. On the other hand, you might be wondering if it’s more cost-effective to just have the unit replaced.
Are you considering whether you need to replace your home’s central heating, ventilation, and air conditioning unit—commonly known as your HVAC system? As a general rule, if your existing HVAC system is more than 15 years old, it’s only a matter of time before it starts to cost more to maintain than it would to replace it with a new system. In addition to higher energy bills brought on by a system that can no longer function at peak efficiency, repair costs will also start to add up as parts are replaced and the ventilation system undergoes major overhauls.
