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? Denver 

Air Conditioning Service & Repair

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.


Repair Heat Pump This article will help to explain what the different parts of a home Heating, Ventilating and Air Conditioning (HVAC) system are and help you understand what work is being specified on an HVAC repair price list. For the purposes of this example, we will look at the components of an all-electric split heat pump system most typical in home HVAC installations.The heat pump itself is the outdoor portion of the system. It consists primarily of the compressor, condenser coil, and fan. It also houses the reversing valve and electrical contractors. This is where your service technician will hook up his pressure gauges to see if there is the correct amount of refrigerant in your system. If refrigerant is needed, it is installed here through a port. The bottle containing the freon will be weighed by a scale before and after filling your system to determine how much was used, and you would be charged by the pound. If there is a refrigerant leak in the coil it can usually be repaired, but all the refrigerant may have to be pumped out and reinstalled. Sometimes the fins on the condenser coil will be bent up due to hail damage or may be dirty. These can be combed out again or cleaned for little cost. If the fan or compressor do not run, or the reversing valve does not change the system from heating to cooling, it is possible that only a contactor may need to be replaced. These contactors, thankfully, are low cost components. But if a fan motor or compressor needs to be replaced, it can be more expensive. The compressor is the most expensive component and can be several hundred dollars to replace. If the condenser coil is badly damaged or the compressor needs to be replaced, it might be time to consider a new heat pump, particularly if much more energy efficient options are available.Indoors you have the air handler, which consists of the evaporator coils, indoor fan, air filtration system, humidifier, and a plenum for air vents. One of the most expensive repairs here can be for an under-slab plenum that has rusted out; this can sometimes require that part of the slab be demolished and reconstructed. It is unusual that anything goes wrong with the evaporator coils, but sometimes they need to be cleaned, which is an inexpensive operation. If the indoor fan motor needs to be replaced, it can be moderately costly. The air filtration system and humidifier usually only require simple repairs, replacement of filters, floats, small motors, etc. There are also some control electronics including the thermostat; these can range in price from inexpensive to moderately costly. If the heat pump outside needs to be replaced, it is possible that you may want to replace the indoor air handler also if it will help provide you with the energy efficiency of a new system. Hopefully this will help you to have a better idea of what you are looking at next time you get a repair bill for your HVAC system. Don't be afraid to ask questions of your service technician, and if you don't feel comfortable with any aspect of the repair or if it's very expensive, be sure to get a second opinion before going forward.

Furnace Repair: Five Signs That Your Furnace Needs Attention

Gas Heating System Service 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. Repair Heat Pump
