Home Heating Contractors

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.

HVAC Installation Companies 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.

HVAC - Heating, Ventilating and Air Conditioning

Furnace Diagnosis 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.
