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.
Window unit air conditioners are installed in an open window. The interior air is cooled as a fan blows it over the evaporator. On the exterior the heat drawn from the interior is dissipated into the environment as a second fan blows outside air over the condenser. A large house or building may have several such units, allowing each room to be cooled separately.
Free cooling systems can have very high efficiencies, and are sometimes combined with seasonal thermal energy storage so that the cold of winter can be used for summer air conditioning. Common storage mediums are deep aquifers or a natural underground rock mass accessed via a cluster of small-diameter, heat-exchanger-equipped boreholes. Some systems with small storages are hybrids, 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-in because the storage acts as a heat sink when the system is in cooling (as opposed to charging) mode, causing the temperature to gradually increase during the cooling season.
“Air conditioners contain refrigerant, which allows the system to run efficiently, releasing heat from the air to cool it. Air conditioners are charged with refrigerant upon installation; a poor charge or a refrigerant leak can cause the system’s refrigerant level to fall below the proper amount. To remedy this, the home AC repair which is performed is a refrigerant recharge, accompanied by fixing the leak if that was the source causing low refrigerant levels.
Modern air conditioning systems are not designed to draw air into the room from the outside, they only recirculate the increasingly cool air on the inside. Because this inside air always has some amount of moisture suspended in it, the cooling portion of the process always causes ambient warm water vapor to condense on the cooling coils and to drip from them down onto a catch tray at the bottom of the unit from which it must then be routed outside, usually through a drain hole. As this moisture has no dissolved minerals in it, it will not cause mineral buildup on the coils. This will happen even if the ambient humidity level is low. If ice begins to form on the evaporative fins, it will reduce circulation efficiency and cause the development of more ice, etc. A clean and strong circulatory fan can help prevent this, as will raising the target cool temperature of the unit's thermostat to a point that the compressor is allowed to turn off occasionally. A failing thermistor may also cause this problem. Refrigerators without a defrost cycle may have this same issue. Dust can also cause the fins to begin blocking air flow with the same undesirable result: ice.
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.
After my initial meeting with HVAC Service I had really high hopes and thought these guys were going to be my HVAC go to company. However, it did not pan out this way whatsoever. Initial estimate meeting - This was the initial meeting I thought I found the go to company. Alberto was friendly, punctual, and knowledgeable. I asked some very basic questions and Alberto was able to explain the why's and why not's of each of my questions. Overall I felt really comfortable with Alberto and was extremely impressed. Then it goes all downhill..... Alberto said they were busy but could either install on the upcoming Saturday. We were going to be out of town and said unfortunately that day did not work. He then proposed the upcoming Tuesday as a possible solution, but just had to confirm with another appointment. I said great. I will review the estimate and call your office to confirm I want to move forward with the install. Within 1-hour of Alberto leaving (probably more like 30 minutes) I called the office to confirm I wanted to move forward with the install and to please confirm that Tuesday will be the install day. The lady on the phone said that she will get in touch with Alberto and call me back. This was on a Friday. On Monday I had not received a call from HVAC Service so I called to follow up. The lady on the phone said they were not able to secure a crane for Tuesday and that the install would not be taking place. Fine, no problem I understand. Two weeks go by and no phone call from HVAC Service regarding install date, or any update at all. I call them to check in to see if they have put me on the schedule and when I can expect to have the AC installed. You can tell by the discussion I had with the lady on the phone that they completely forgot about me and have not scheduled anything. She says she needs to get in contact with the owner because she has no idea on the availability of the crane. I was told that she would call me back by the end of the day with an update. Surprise, surprise, no phone call. I call to follow up at the end of the next day and she said that she has not been able to get in touch with the owner. By this time, I am starting to get frustrated because I am starting to get the run around. I question her if I am even on the schedule or if they attempted to schedule a crane. She says they are extremely busy and that she does not know. So I say, basically I have waited over 2 weeks and you have not put me on the schedule and I am at the end of the install line. No answer. I tell her to talk to her boss and find out what is happening, and I will think about what direction I want to move in at this point. Monday the following week, no phone calls, or follow up. I call to get an update and am told that they cannot install my system because they don't have time. I ask what does that mean, one year? One week? Until the end of summer they say. What does that mean I ask? They say at the end of September. I say thank you for wasting 1 month of my time. How could they have served me better without serving me? 1. Be honest and let me know as soon as possible that the install was going to be delayed and probably not happen until the end of summer. Don't waste a month of my time. I could have reached out to a different company in the time I was waiting for them. 2. Communicate! the thing that upsets me the most is I was the one making all the calls to them. Not once did they ever call me to say we have not forgot about you, or this is what is happening. 3. Provide recommendations on other contractors who could have helped me once they realized they were too busy. I am pretty disappointed it came to this review because I really liked this company and wanted to do work with them. It is a family run business, and reminded me of the HVAC business my dad owned. Beware once you are the one that has to start calling them for updates, or to follow up; your time is probably best served by calling a different contractor.

Most modern air-conditioning systems feature a dehumidification cycle during which the compressor runs while the fan is slowed as much as possible to reduce the evaporator temperature and therefore condense more water. When the temperature falls below a threshold, both the fan and compressor are shut off to mitigate further temperature drops;[clarification needed] this prevents moisture on the evaporator from being blown back into the room. When the temperature rises again,[clarification needed] the compressor restarts and the fan returns to low speed.

Ventilation is the process of changing or replacing air in any space to control temperature or remove any combination of moisture, odors, smoke, heat, dust, airborne bacteria, or carbon dioxide, and to replenish oxygen. Ventilation includes both the exchange of air with the outside as well as circulation of air within the building. It is one of the most important factors for maintaining acceptable indoor air quality in buildings. Methods for ventilating a building may be divided into mechanical/forced and natural types.
A home that is too dry in the winter can affect the health of your entire family, causing itchy skin, chapped lips, and aggravating allergies and colds. A whole-home humidifier improves the air quality of your home by adding water vapor through your HVAC system. Having Brubaker Inc. install a humidifier to your HVAC system is a simple step that adds immediate relief and comfort throughout your home.
Natural ventilation is the ventilation of a building with outside air without using fans or other mechanical systems. It can be via operable windows, louvers, or trickle vents when spaces are small and the architecture permits. In more complex schemes, warm air is allowed to rise and flow out high building openings to the outside (stack effect), causing cool outside air to be drawn into low building openings. Natural ventilation schemes can use very little energy, but care must be taken to ensure comfort. In warm or humid climates, maintaining thermal comfort solely via natural ventilation might not be possible. Air conditioning systems are used, either as backups or supplements. Air-side economizers also use outside air to condition spaces, but do so using fans, ducts, dampers, and control systems to introduce and distribute cool outdoor air when appropriate.
Many disconnect blocks contain two cartridge fuses. Check them before you proceed with repairs (Photo 3). A blown fuse is a sign of a failing part inside the condensing unit. So don’t just replace it and think you’ve solved the problem. Instead, replace the parts we show here. Then install new fuses and fire up the unit. If it blows again, call a pro—you’ve got more serious issues.
