The condensed, pressurized, and still usually somewhat hot liquid refrigerant is next routed through an expansion valve (often nothing more than a pinhole in the system's copper tubing) where it undergoes an abrupt reduction in pressure. That pressure reduction results in flash evaporation of a part of the liquid refrigerant, greatly lowering its temperature. The cold refrigerant is then routed through the evaporator. A fan blows the interior warm air (which is to be cooled) across the evaporator, causing the liquid part of the cold refrigerant mixture to evaporate as well, further lowering the temperature. The warm air is therefore cooled and is pumped by an exhaust fan/ blower into the room. To complete the refrigeration cycle, the refrigerant vapor is routed back into the compressor. In order for the process to have any efficiency, the cooling/evaporative portion of the system must be separated by some kind of physical barrier from the heating/condensing portion, and each portion must have its own fan to circulate its own "kind" of air (either the hot air or the cool air).
Most of the time, diagnosing problems is simple and other times it can be a complicated process where the HVAC technician calls in another HVAC technician. The technician may call in an HVAC manufacturer representative. Residential and commercial heating and cooling is important and you want the best possible HVAC air conditioning and heating service. It does not matter whether you have a Carrier Air Conditioner, Trane Air Conditioners, or need a replacement, whatever, it is best to get a qualified technician to look at your system before a decision is made to repair or replace the air conditioner or heat pump systems.
In order to get the most out of your equipment, we highly recommend proper preventative HVAC maintenance. You’ll want to make sure from the outset that you have access to skilled and knowledgeable technicians who have been factory-trained to service your particular model, since different systems require different highly specific modifications. It’s advisable to find a reputable HVAC dealer in the Atlanta area that guarantees their work and offers annual service contracts to their customers to ensure necessary seasonal maintenance is always being performed regularly. Many times, timely adjustments and filter changes that are done on a regular basis can wind up saving you from breakdowns that always seem to occur right when you need your system the most.
R22 (also known as HCFC-22) has a global warming potential about 1,800 times higher than CO2. It was phased out for use in new equipment by 2010, and is to be completely discontinued by 2020. Although these gasses can be recycled when air conditioning units are disposed of, uncontrolled dumping and leaking can release gas directly into the atmosphere.

The time it takes to install an AC unit and the associated cost depends on the square footage of your home. Many homeowners spend between $3,677 to $7,151 for a contractor to put in a new central air system.A family with a 2,000-square-foot house that already has a forced-air heating unit can expect to pay $3,500 to $4,000 for a cooling system. If technicians don't need to make any changes to the duct-work, then the project should take them an average of two to three days.
The performance of vapor compression refrigeration cycles is limited by thermodynamics. These air conditioning and heat pump devices move heat rather than convert it from one form to another, so thermal efficiencies do not appropriately describe the performance of these devices. The Coefficient-of-Performance (COP) measures performance, but this dimensionless measure has not been adopted. Instead, the Energy Efficiency Ratio (EER) has traditionally been used to characterize the performance of many HVAC systems. EER is the Energy Efficiency Ratio based on a 35 °C (95 °F) outdoor temperature. To more accurately describe the performance of air conditioning equipment over a typical cooling season a modified version of the EER, the Seasonal Energy Efficiency Ratio (SEER), or in Europe the ESEER, is used. SEER ratings are based on seasonal temperature averages instead of a constant 35 °C (95 °F) outdoor temperature. The current industry minimum SEER rating is 14 SEER.
Per hour service charges are not the only way companies charge their customers. There are also service companies that flat rate their services. Either way, you pay, you want the service and troubleshooting done in a quick and efficient manner with a guarantee. Do your research before selecting a company to provide reliable, honest service to your home. If you know what the problem is then the company can likely give you an estimate over the phone. Some will while some do not. Why? Because they likely want to verify the problem to make sure it is a correct assessment. It can be a complex issue and what you think it is it may not be the problem. So you can expect to pay for a service call and troubleshooting charge. Most HVAC service companies do not give free estimates on repairs.
If your air conditioner’s condenser coils, which are located in the outdoor unit, freeze up, your system will not run properly. Poor airflow through your cooling system can cause ice to form on the coils. Obstructions are typically the cause – such as dirty air filters or blocked return air ducts. Low refrigerant could also be the cause, requiring a refrigerant charge. A home AC repair technician can diagnose the issue behind your frozen coils, resolve it, and safely thaw your coils to restore cooling in your home.”

It can be hard to make the decision to replace or repair your AC unit. However, in many cases, homeowners call in HVAC professionals to check their units and provide a second opinion. A technician can tell you if there’s plenty of life left in your old air conditioning unit or that it’s time to let it go and get a new one. Your HVAC technician may check out your home’s insulation quality, too. You could increase your system’s effectiveness by improving the insulation.
Without proper ventilation, carbon monoxide can be lethal at concentrations of 1000 ppm (0.1%). However, at several hundred ppm, carbon monoxide exposure induces headaches, fatigue, nausea, and vomiting. Carbon monoxide binds with hemoglobin in the blood, forming carboxyhemoglobin, reducing the blood's ability to transport oxygen. The primary health concerns associated with carbon monoxide exposure are its cardiovascular and neurobehavioral effects. Carbon monoxide can cause atherosclerosis (the hardening of arteries) and can also trigger heart attacks. Neurologically, carbon monoxide exposure reduces hand to eye coordination, vigilance, and continuous performance. It can also affect time discrimination.
Central, "all-air" air-conditioning systems (or package systems) with a combined outdoor condenser/evaporator unit are often installed in North American residences, offices, and public buildings, but are difficult to retrofit (install in a building that was not designed to receive it) because of the bulky air ducts required. (Minisplit ductless systems are used in these situations.) Outside of North America, packaged systems are only used in limited applications involving large indoor space such as stadiums, theatres or exhibition halls.
I needed a replacement for my heater. I called Bill Howe and they promptly fitted me into their schedule. The person who arrived, Laurence C. thoroughly tested my furnace and pointed out the problem. I decided to replace it. They arrived on the day to install it. The two men, Jose Gomez and Javier Diaz promptly went to work. They were clean, efficient and respectful of my home. I would gladly recommend Bill Howe for your heating and plumbing needs. They were great!!
Clean air delivery rate is the amount of clean air an air cleaner provides to a room or space. When determining CADR, the amount of airflow in a space is taken into account. For example, an air cleaner with a flow rate of 100 cfm (cubic feet per minute) and an efficiency of 50% has a CADR of 50 cfm. Along with CADR, filtration performance is very important when it comes to the air in our indoor environment. Filter performance depends on the size of the particle or fiber, the filter packing density and depth and also the air flow rate.
Air conditioning can also be provided by a process called free cooling which uses pumps to circulate a coolant (typically water or a glycol mix) from a cold source, which in turn acts as a heat sink for the energy that is removed from the cooled space. Common storage media are deep aquifers or a natural underground rock mass accessed via a cluster of small-diameter boreholes, equipped with heat exchanger. Some systems with small storage capacity are hybrid systems, using free cooling early in the cooling season, and later employing a heat pump to chill the circulation coming from the storage. The heat pump is added because the temperature of the storage gradually increases during the cooling season, thereby declining its effectiveness.
If your air conditioner is old, consider buying an energy-efficient model. Look for the ENERGY STAR® and EnergyGuide labels — qualified central units are about 15% more efficient than standard models. New residential central air conditioner standards went into effect on January 1, 2015; see the efficiency standards for central air conditioners for details, and consider purchasing a system with a higher SEER than the minimum for greater savings.
In 2006, a new HVAC rule went into affect for residential air conditioners, requiring all to have a Seasonal Energy Efficiency Ratio (SEER) of 13 or higher. As you might expect, the more efficient the unit is (or newer), the lower your average AC repair cost will be. Keep in mind, if for some reason your high-efficient repair bill is high, you’re still saving on energy costs every month through your electric and gas bills.
