Many factors influence the final price the consumer pays for the item at purchase time. If the supply is tight and the product is in great demand, a dealer may mark up his price higher than the manufacturer's suggested retail price, or MSRP, as long as customers are willing to pay it. To bring customers into the store or to clear away older inventory, a retail store may lower the price below the MSRP with a sale.
The top-of-the-line Carrier Infinity ICS Modulating is the most expensive furnace Carrier makes. All three Infinity models feature a variable-speed blower and Comfort Heat technology to prevent the home from wide variations in temperatures as the furnace cycles on and off. They also offer a 10-year warranty on parts and limited lifetime on the heat exchanger. The MSRP for the line is $3,199 for the ICS, $2,949 for the Infinity 96 and $1,699 for the Infinity 80.
The Carrier Infinity air conditioner systems range from 2 to 5 tons in size. The systems boast Energy Star certifications for energy efficiency, meaning they can significantly reduce your energy bill when replacing older equipment. Carrier has made an effort to reduce the noise for the appliances with special compressors and insulation. The units hook to the Internet and use a five-day weather forecast to program themselves. The 5-ton unit has an MSRP of $3,579, whereas the 2-ton unit is $2,599
A heat pump is like an air conditioner turned inside out. Instead of taking hot air from the inside and transferring it to the outside, it takes what heat it can find on the outside and transfers it into the home, even on cold days. The heat pumps offer many of the same benefits as the AC units, such as energy efficiency, noise reduction and Internet control. The 5-ton heat pump has a $5,199 MSRP, while the smallest -- at 2 tons -- carries an MSRP of $3,899.
