You're a homeowner and determined your home's air conditioning needs fixing or needs to be replaced with a newer, more efficient system. You're all set to get moving. What's the optimal way to get a high quality HVAC contractor who will do a good job for a fair price? What could you look for in an air conditioning contractor to obtain this work? Cherry Creek 

Home HVAC Maintenance

When homeowners choose to repair an air conditioning system or replace the unit with a newer one, they're often plagued by worries that their family will swelter while the job is completed.  These concerns are perfectly normal and common among many homeowners looking for HVAC fixes or air conditioner repair specialists.

Furnace Boiler Repair A condenser is a device that is used to liquefy gas by cooling it. In HVAC equipment, hot discharge gas (refrigerant vapor) from the compressor enters the condenser coils at the top and is condensed, drains out of the condenser to a receiver located near the bottom. The condenser coil is located along with the compressor and controlling devices in the condensing unit. In a remote or split system air conditioning installation, the condensing unit is located outdoors. Condensers are available in a variety of sizes and designs that include plain tube, finned tube and plate type, series-pass and parallel pass units.Condensers are classified by their cooling method. The three main types are broken down to: Air-cooled condensers Combined air and water-cooled condensers Water-cooled condensers Air-Cooled CondensersAn air-cooled condenser consists of a coil of ample surface that air is blown by a fan or induced by natural draft. This type of condenser is universally used in small capacity refrigerating units. Mostly designed for residential or small office air conditioners.Air-chilled condensers should be kept from free from dirt, lint and other foreign materials because they tend to reduce the airflow around the tubes and fins if they are allowed to accumulate just like evaporators.Combined Air- and Water-cooled CondensersThis type of condenser is also know as an evaporative condenser and consists of a coil cooled by water sprayed from above and then cold air enters from the bottom and is blown across the coils. As water evaporates from the coil it creates a cooling effect that condenses the refrigerant within the coil. The refrigerant gas in the coil is hot which changed to the liquid state by combining the sprayed water and the large column of moving air supplied by the fan. The water that does not evaporate is recirculated by means of a pump.Water-Cooled CondensersA water-cooled condenser is similar to a steam surface condenser in that cooling is accomplished by water alone that circulates through tubes or coils enclosed in a shell. IN a water-cooled condenser the refrigerant circulates through the annular space between the tubes or coils. Because of its construction, a water-cooled condenser is also referred to as a double-pipe condenser. Because an evaporative condenser is not wasteful of water, large compressor installations are possible in areas where water is scarce. Tests have shown that the amount of water required will not exceed the.03 gpm per ton of refrigeration. This is one of the eco-friendly reasons to use this type of condenser. Evaporative condensers also eliminate water water disposal problems and provide the most economical means of cooling refrigerant gases of standard air conditioners.

Heating & Air Conditioning Contractors A common complaint about heating and cooling systems is wide temperature differences between rooms and between stories in homes. Heating and air conditioning (HVAC) contractors often refer to correcting temperature differences between areas as balancing the system. An HVAC system that is properly sized and properly installed should require only minor adjustment to achieve a reasonable temperature balance. In practice, HVAC system sizing and installation errors are common and can make balancing difficult.There are several heating and cooling performance standards for HVAC systems. The International Residential Code (IRC) heating performance standard requires that the system maintain a temperature in the home of at least 68Ës F. The IRC has no performance standard for cooling. The National Association of Home Builders (NAHB) heating performance standard is 70Ës F. and the cooling standard is 78Ës F. or 15Ës F. below an outside air temperature of 95Ës F. The performance standard temperature is often measured near the center of the room and about five feet above the floor. States or cities may have different performance standards. The Arizona cooling performance standard is 78Ës F. or 30 degrees below the outside air temperature. These national and local standards usually apply to every room in the home. In cooling mode, for example, if the thermostat temperature is 78Ës F., the temperature in every room controlled by that thermostat should be at least 78Ës F. A one or two degree variance from the thermostat temperature is usually allowed.Balancing is affected by numerous factors that can change based on the time of day and the season of the year. Some factors that affect balancing include: room location (south and west facing rooms can be more difficult to cool), size, quality and location of windows and doors, room size and ceiling height, size and location of supply and return registers, thermostat location, and location of the air handler relative to the room (the air handler must push air further through ducts in unconditioned space).Because a balancing problem can have multiple causes, solving the problem can require multiple solutions. Here are some simple potential solutions for balancing problems. Confirm that all supply and return registers are open and unobstructed. Confirm that filters have been cleaned or changed per manufacturer's instructions. Confirm that ducts are sized and installed according to recommended standards. Confirm that insulation is installed properly and in the required amount. Install sun screens on south and west facing windows in high heat areas. Plant deciduous trees on the south and west sides (sun in winter, shade in summer). Improve air flow in rooms with doors by providing a return air path if none exists. If these simple solutions do not produce satisfactory results, other solutions may be required. These solutions may include changing the supply and/or return duct configuration and adding zones that are separately controlled by their own thermostats. AC Furnace Repair
