Be cautious with companies that offer “whole house air duct cleaning,” urges the NADCA. The company may be using unscrupulous tactics to upsell you once they get started. Before any work begins, always clarify in writing what the job entails and what the cost will be. To protect yourself against fraud, read customer reviews and verify that your HVAC cleaning service has applicable licenses and certifications.
Air conditioners often use a fan to distribute the conditioned air to an occupied space such as a building or a car to improve thermal comfort and indoor air quality. Electric refrigerant-based AC units range from small units that can cool a small bedroom, which can be carried by a single adult, to massive units installed on the roof of office towers that can cool an entire building. The cooling is typically achieved through a refrigeration cycle, but sometimes evaporation or free cooling is used. Air conditioning systems can also be made based on desiccants (chemicals which remove moisture from the air) and subterraneous pipes that can distribute the heated refrigerant to the ground for cooling.

In the case of heated water or steam, piping is used to transport the heat to the rooms. Most modern hot water boiler heating systems have a circulator, which is a pump, to move hot water through the distribution system (as opposed to older gravity-fed systems). The heat can be transferred to the surrounding air using radiators, hot water coils (hydro-air), or other heat exchangers. The radiators may be mounted on walls or installed within the floor to produce floor heat.
The employees were on time, professional, and extremely thorough while addressing a particularly difficult situation. The entire time Saul, the supervisor of the team, kept me informed, and educated me about any process that I may have not completely understood. The team was courteous to the residents they encountered, and made sure not to leave evidence that they had even been there. Great job!
Focus first on sealing ducts that run through the attic, crawlspace, unheated basement, or garage. Use duct sealant (mastic) or metal-backed (foil) tape to seal the seams and connections of ducts. After sealing the ducts in those spaces, wrap them in insulation to keep them from getting hot in the summer or cold in the winter. Next, look to seal any other ducts that you can access in the heated or cooled part of the house. See our Duct Sealing Fact Sheet (787KB) for more information.
Since the 1980s, manufacturers of HVAC equipment have been making an effort to make the systems they manufacture more efficient. This was originally driven by rising energy costs, and has more recently been driven by increased awareness of environmental issues. Additionally, improvements to the HVAC system efficiency can also help increase occupant health and productivity. In the US, the EPA has imposed tighter restrictions over the years. There are several methods for making HVAC systems more efficient.
The most recognized standards for HVAC design are based on ASHRAE data. The most general of four volumes of the ASHRAE Handbook is Fundamentals; it includes heating and cooling calculations. Each volume of the ASHRAE Handbook is updated every four years. The design professional must consult ASHRAE data for the standards of design and care as the typical building codes provide little to no information on HVAC design practices; codes such as the UMC and IMC do include much detail on installation requirements, however. Other useful reference materials include items from SMACNA, ACGIH, and technical trade journals.
Before selecting the installation location of air conditioner, several main factors need to be considered. First of all, the direction of air flow from the indoor units should not fall on the place of rest or work area. Secondly, there should not be any obstacles on the way of the airflow that might prevent it from covering the space of the premises as much as possible. The outdoor unit must also be located in an open space, otherwise the heat from the house will not be effectively discharged outside and the productivity of the entire system will drop sharply. It is highly advisable to install the air conditioner units in easily accessible places, for further maintenance during operation.
“We had a great experience with Robinson’s! The office staff, then the gentleman who helped me with questions over the phone and Kyle, our service tech, were all great and very easy to work with. They gave me a time frame for when to expect Kyle the same day. A phone call to let me know he was on his way. A text with picture so I knew who to be expecting. Kyle arrived on time and was very knowledgeable and friendly. He did a great job. You could tell he liked his job. Prices were reasonable. We will be using and recommending Robinson’s Air – Wichita Falls in the future.”
5) Check certifications. Many HVAC professionals belong to the Air Conditioning Contractors of America (ACCA) or the Sheet Metal and Air Conditioning Contractors’ National Association (SMACNA). Both sites provide listings of HVAC contractors by area. Look for contractors whose technicians are certified by North American Technician Excellence (NATE) and partnered with ENERGY STAR.

Ventilation, air conditioning and heating systems require regular maintenance for them to work efficiently. You’ll likely need tune-ups and repairs for them at some point during their lifespan. However, no matter how much preventative maintenance you put into your HVAC system, there comes a time when repairs aren’t enough anymore and it’s time for a replacement.
Tony was very good - appointment took a while to book, but that's understandable, since they have built a great business and have lots of people calling them. Tony came this Sunday morning, and once he saw the HVAC unit, knew exactly what the issue was - fixed it in under 20 mins, and my AC was back to normal Pricing is fair - parts, labor and diagnostic fee and tax I would definitely recommend him to anyone needing his services. He's honest, very nice to deal with even made my toddler son smile. 5 STARS ALL THE WAY!
"Customer service was great, and the price was in-line with other places, and fast service. We had a whole replacement of the outside and inside. I would have liked to see a better install for the furnace and new thermostat - the new thermostat should have gone where the old one was, and even tho the new furnace was a tight fit, they didn't offer to come back and repair the case molding, or give me a discount on the damage done, and I believe they should have put a disconnect box on the outside of the home, to make it easier for any future repairs needed. Other than that, am very happy with the cooling and heating!"
In variable climates, the system may include a reversing valve that switches from heating in winter to cooling in summer. By reversing the flow of refrigerant, the heat pump refrigeration cycle is changed from cooling to heating or vice versa. This allows a facility to be heated and cooled by a single piece of equipment by the same means, and with the same hardware.
The condenser fan is another important HVAC element that must be maintained. Condenser fans that contain oil ports should be lubricated at least annually. The outside condenser should also be shielded from direct sunlight if possible. Keeping vegetation at least two feet away from outdoor HVAC units will also promote higher performance and potentially lower energy bills due to higher efficiency. The further away vegetation is, the better an HVAC unit will operate.

Was not satisifed with this company. This person came out and took 10 minutes only to tell me that my unit would not last for a year and that I needed to have it replaced! I'm not sure if he was very knowlegable or if he was just plain lazy and do not even try to fix the problem. He just wanted to install a brand new system because he was both and of course, that's much more money for him!
My mom just received service from this company. She paid $609 to have her frion replaced. After two uses the AC stops working. A young rep comes out to the house again and notifies her that her entire AC unit and furnace need to be replace for just shy of ten grand, though when her frion was refilled she was told that her system should last another five years. When they came back to tell her how her entire system needed to be replaced, they were generous enough to offer her a $300 credit on the nearly $10,000 estimate of replacing the entire system that was working fine until they touched it. My best assumption would be that there is a mishap with the system is due to their negligence. Id suggest using another company other than these scam artists. Update: Alberto soon messages me about the negative review telling me how I am wrong and that they are the best mechanical contractors in the Bay Area. Literally told me that I was wrong. Not sure how you can get much more arrogant than that. Stay clear of these clowns.
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.
In 1906, Stuart W. Cramer of Charlotte was exploring ways to add moisture to the air in his textile mill. Cramer coined the term "air conditioning", using it in a patent claim he filed that year as an analogue to "water conditioning", then a well-known process for making textiles easier to process. He combined moisture with ventilation to "condition" and change the air in the factories, controlling the humidity so necessary in textile plants. Willis Carrier adopted the term and incorporated it into the name of his company.

Ventilating or ventilation (the V in HVAC) is the process of exchanging or replacing air in any space to provide high indoor air quality which involves temperature control, oxygen replenishment, and removal of moisture, odors, smoke, heat, dust, airborne bacteria, carbon dioxide, and other gases. Ventilation removes unpleasant smells and excessive moisture, introduces outside air, keeps interior building air circulating, and prevents stagnation of the interior air.
The use of CFC as a refrigerant was once common, including the refrigerants R-11 and R-12 (sold under the brand name Freon-12). Freon refrigerants were commonly used during the 20th century in air conditioners due to their superior stability and safety properties. When they are released accidentally or deliberately, these chlorine-bearing refrigerants eventually reach the upper atmosphere. Once the refrigerant reaches the stratosphere, UV radiation from the Sun homolytically cleaves the chlorine-carbon bond, yielding a chlorine radical. These chlorine radicals catalyze the breakdown of ozone into diatomic oxygen, depleting the ozone layer that shields the Earth's surface from strong UV radiation. Each chlorine radical remains active as a catalyst until it binds with another radical, forming a stable molecule and quenching the chain reaction.

An air conditioner’s cooling process produces condensation, which normally flows away from the equipment, causing no problem. If there is a clog in the condensate drain lines or drip pan, or if outdoor humidity levels are high, moisture may back up into your air conditioner. Excess condensation will increase indoor humidity levels and hinder the air conditioner’s performance. It could also cause damage to your air conditioner’s components.
