Before opening the electrical cover on the A/C unit, be sure to shut off all power to the compressor unit and the indoor furnace or air handler, and verify that it is off. Note that this may mean shutting off a circuit breaker that serves the furnace and air handler, and then, near the compressor, pulling out the disconnect block (or shutting off the 220-volt power) to the outdoor compressor.

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.

This company deserves more than five stars. They didn't just replace my heater and air conditioner, they built me a new system for my house. Going above and beyond is a understatement. Steve's staff were 2 of the nicest workers I've come across in a long time. Friendly, knowledgeable, and very clean. Truly a top rated company. Thanks Steve.   Great job.
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.
In addition, if water is condensed in the room, the amount of heat previously needed to evaporate that water also is re-released in the room (the latent heat of vaporization). The dehumidification process is the inverse of adding water to the room with an evaporative cooler, and instead releases heat. Therefore, an in-room dehumidifier always will warm the room and reduce the relative humidity indirectly, as well as reducing the humidity directly by condensing and removing water.

Search results are sorted by a combination of factors to give you a set of choices in response to your search criteria. These factors are similar to those you might use to determine which business to select from a local Yellow Pages directory, including proximity to where you are searching, expertise in the specific services or products you need, and comprehensive business information to help evaluate a business's suitability for you. “Preferred” listings, or those with featured website buttons, indicate YP advertisers who directly provide information about their businesses to help consumers make more informed buying decisions. YP advertisers receive higher placement in the default ordering of search results and may appear in sponsored listings on the top, side, or bottom of the search results page.

Air duct cleaning is done by heating, ventilation and air conditioning (HVAC) professionals. The pros use industrial-strength, truck-mounted vacuums and powerful brushes and hoses to clean inside the metal ducts that make up your forced air heating and cooling system. The Environmental Protection Agency recommends duct cleaning if there is “substantial visible mold growth inside hard surface ducts, ducts that are infested with vermin such as rodents or insects, or ducts that are clogged with excessive amounts of dust and debris and/or particles are actually released into the home from your supply registers.”

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 discussing faulty AC system symptoms with you, Jiffy Lube® technicians begin the service by visually inspecting the air conditioning compressor drive belt, serpentine belt and all accessible components for cracks, leaks or damage. Then they check the operation of the air conditioning compressor. If no leaks or damage are found, they evacuate the refrigerant from the system, vacuum test it, and recharge the air conditioning system using the appropriate refrigerant according to your vehicle manufacturer's recommendations.
Advantages of the ductless system include smaller size and flexibility for zoning or heating and cooling individual rooms. The inside wall space required is significantly reduced. Also, the compressor and heat exchanger can be located farther away from the inside space, rather than merely on the other side of the same unit as in a PTAC or window air conditioner. Flexible exterior hoses lead from the outside unit to the interior one(s); these are often enclosed with metal to look like common drainpipes from the roof. In addition, ductless systems offer higher efficiency, reaching above 30 SEER.[39]

Sometimes a heating and air conditioning system just needs to be repaired rather than completely replaced. You may need air conditioning repair services if there is leaking around the outside unit, the air coming into the house isn't hot or cool enough, the unit is short-cycling or constantly turning on and off, using the system is consistently resulting in higher-than-normal energy bills, or if there is excessive noise during startup and operation.

Replacing a capacitor is easy. Just take a photo of the wires before disconnecting anything (you may need a reference later on). Then discharge the stored energy in the old capacitor (Photo 4). Use needle-nose pliers to pluck one wire at a time from the old capacitor and snap it onto the corresponding tab of the new capacitor. The female crimp connectors should snap tightly onto the capacitor tabs. Wiggle each connector to see if it’s tight. If it’s not, remove the connector and bend the rounded edges of it so it makes a tighter fit on the tab. When you’ve swapped all the wires, secure the new capacitor (Photo 5).
