I have no idea what a barrel is??? In chilled water systems the evaporator and condensers sometimes use what is called a chiller barrel for the evaporator and/or the condenser but for most residential system it is a rarity to find a chilled water system installed. Are you talking about a commercial system chiller. 7.1 KW is not a very big system but they do exist in light commercial and as mentioned in residential.
Central air conditioners are more efficient than room air conditioners. In addition, they are out of the way, quiet, and convenient to operate. To save energy and money, you should try to buy an energy-efficient air conditioner and reduce your central air conditioner’s energy use. In an average air-conditioned home, air conditioning consumes more than 2,000 kilowatt-hours of electricity per year, causing power plants to emit about 3,500 pounds of carbon dioxide and 31 pounds of sulfur dioxide.
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!

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!


They were quick to come out and diagnose the problem with my furnace, but I thought the estimate of $549 a bit high to replace the circuit board.  So called around and found Leo's Appliance in Concord that sells appliance parts and the circuit board was only $90.49 - that is the retail cost to me, so I imagine the wholesale cost is a lot less.  So BEWARE of this company since they wanted $500!!! to replace the circuit board which is located right in the front of the furnace - extremely easy to access.  I hate it that you cannot trust repair companies.

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.

The cost of service varies widely from one region to the next so it is next to impossible to give you prices for air conditioning service. The best way to check prices is to shop around. Be aware though that sometimes the cheapest price for HVAC air conditioning and heating service and repair is not always the best way to go. Your main concern should be getting knowledgeable HVAC service technicians, reliability, punctuality, honesty, integrity, and guaranteed work.
While it should be rare to have problems occur with new equipment, it does happen. When it does, you want a good troubleshooter who is knowledgeable and can make the diagnosis and repair in a timely and efficient manner. That means you want that HVAC contractor who sends their technicians to HVAC technical seminars and factory sponsored training classes. That can make the difference between solving the problem quickly and efficiently in hours or being frustrated waiting days or weeks to have the problem solved. Take the time to choose your contractor wisely and it will save you a lot of heartache and frustration.

To be honest, an HVAC technician’s work goes beyond more than installation, maintenance and repair. Most people are increasingly spending more time inside the home, so indoor air quality, home energy savings and total comfort have become even more important. There are several choices and solutions when it comes to HVAC systems, and our experts will consult with you every step of the way and work with you to achieve your goals.
