To compare the cost of a replacement heating, ventilation and air conditioning unit, it is important to consider factors, such as price ranges for different brands of systems, contractor and labor costs, and energy efficiency for various units. A homeowner may need to replace an HVAC unit due to either a room addition to a home or a unit that is too old and does not work properly, as noted by HomeAdvisor.com.
An HVAC system may last up to 20 years. After this time, homeowners may need to replace the unit for a more modern model that has better efficiency. HVAC system brands include Trane, Carrier, Lennox, Rheem, American Standard and Amana, as noted by HomeAdvisor.com. As of 2015, the American Standard line has units ranging from $3,800 to $4,900. Similarly, the price ranges for Lennox and Carrier can be from $3,400 to $4,600.
Comparing the SEER rating of models can give homeowners an idea of their energy efficiency. For example, the Trane XL13c and Carrier's Comfort Series ES48 have a 13 SEER rating, while the American Standard Gold line units have a 14.25 rating. The higher the SEER rating, the lower the average yearly cooling cost is likely to be for the unit.
It is important to compare estimates from different contractors and choose a company which offers competitive pricing and also has the proper credentials to design and install the system. Other factors to consider are any labor costs associated with the upgrade.
