Buying a furnace and AC system will save you money compared to individually buying each component. It will almost always cost more to buy each component separately, and will also cost more for additional installation calls.

Frequently Asked Questions
Yes, your furnace and air conditioner do work together. They both use the same air blower to deliver cold or warm air through your duct work, and both work with your thermostat to keep your home at your preferred temperature.
It's recommended to replace your system all together, but not required. If one component is much newer than the others you may want to wait to replace that unit. However, replacing all at the same time will save you on equipment cost and installation.
We do not recommend installing a system yourself. There are many risks involved when attempting to do so, such as damaging the equipment and voiding your warranty. We suggest reaching out to your local contractor in order to install your system. However, we do have DIY Mini Split Systems that you can install yourself. Mini split systems are an alternative to traditional HVAC that focus on "zoned" heating and cooling. We have DIY mini split systems available for up to 5 zones (rooms). Check out our full selection here on our DIY Mini-Split System page.
The cost of buying a furnace and AC unit can vary widely, typically ranging from $4,000 to $10,000 or more, depending on the type, size, and efficiency of the units. However, these AC and heating systems can offer long-term savings on energy bills, which can offset the initial expense. The total cost will depend on factors like the size and type of system, the complexity of installation, and any additional upgrades you select. At HVACDirect.com, financing options and rebates are available to help make the purchase that fits your budget.
The most cost-effective option for a new central air conditioner and furnace system is to purchase your equipment at wholesale prices from HVACDirect.com and hire a local contractor for installation. We can help you save thousands on upfront costs and offer flexible financing options to suit your budget.
The most expensive part of a furnace and AC system is often the compressor, which can cost up to $4,000. A well-maintained compressor can last many years, making it a valuable investment. Regular maintenance can help extend the lifespan of the compressor and prevent costly repairs or replacements. At HVACDirect.com, our goal is to help you save on upfront expenses by offering HVAC equipment at wholesale rates.
