What is an average cost of replacing HVAC? As of 2014, a building owner can expect to pay between $5,000 and $11,000 to replace the residential HVAC system. The cost of replacing an HVAC system varies greatly. The type of system, installation costs and any necessary changes or modifications to the structure can dramatically affect the cost of replacing the HVAC system. What is a HVAC unit?

Lesser-known brands may be cheaper, but the quality of the system may be questionable. Careful research of available systems and brand reputation may assist in determining the appropriate system for the building. For installation, contractors' rates may differ, so it is best to get quotes from multiple contractors prior to making a decision. The building owner may be expected to pay for necessary repairs or modifications to the existing system in addition to the cost of installation.

Accurate measurements of the building will help to ensure the proper selection of replacement system. The building owner must also provide as much information as possible about the existing system. This will allow both contractors and retailers to assist the owner in making an informed selection for a replacement HVAC system. How do you compute proper duct sizes for an HVAC system?

Leaks: The #1 ProblemEst. Repair Cost: $50 to $200A MSN Autos survey of repair shops around the country confirms that system leaks are the number-one auto air conditioning problem faced by consumers.

"Leaks account for roughly 80 percent of the problems we see day in and day out," the manager of a Brookfield, IL, repair shop told MSN Autos. Other shops concurred, reporting that leak repair accounted for 70-80 percent of their air conditioning work. Leaks can occur anywhere in the air conditioning system, wherever refrigerant passes from one component to another.Fortunately, leaks are the easiest and least-expensive A/C problems to fix, with replacement of faulty gaskets or worn hoses as the usual solutions. If you're lucky, leak repair will set you back around $50. But prepare yourself for a figure up to four times that amount. "Leaks usually run between $150 and $200," the service manager of an Irvine, CA, repair shop told MSN Autos-an estimate echoed by many shops we surveyed. Compressor FailureEstimated Repair Cost: $500 to $1,000The compressor is the pump that compresses and circulates the refrigerant through the system, transferring heat from the cabin to the outside environment.

In most systems, the compressor contains a magnetic clutch that engages when you turn on the air conditioning in your vehicle. This clutch can fail, or other compressor components can simply wear out. As the heart of the A/C system, the compressor is costly to fix. Repairs start around $500, but as a service manager at a Phoenix Toyota dealership told us, "Compressor replacement can be spendy, sometimes going over $1,000." System ContaminationEstimated Repair Cost: $300 to $2,000Contamination is another common air conditioning problem. Contamination occurs when an A/C system is serviced using equipment that has been exposed to more than one type of refrigerant. There are two primary refrigerant types: R-12, used in older cars, and the environmentally friendly R-134a, used in all cars built since 1994. The two refrigerants are completely incompatible and any exposure of one to the other during servicing contaminates parts within the A/C system. Decontamination involves flushing and recharging the entire system, as well as replacing any or all of the following components: compressor, condenser, evaporator and dryer.
