Frequently Asked Question
What is the $5,000 rule for HVAC?
For example, if a 12-year-old unit needs a $400 repair, the total is $4,800, which makes repairing a strong, budget-friendly choice. It’s a helpful starting point, and you can pair it with a technician’s opinion and your system’s overall condition for extra confidence.
How much to replace HVAC for a 2,000 sq ft house?
Prices vary in a helpful, predictable way based on the system type (heat pump vs furnace and AC), efficiency level (SEER), and whether your ductwork needs updates. If your ducts are in good shape and the installation is straightforward, it is often easier to stay closer to the lower end of the range, making your overall replacement budget go further.
Will upgrading my HVAC system help me qualify for energy rebates or tax incentives offered in Illinois or by local utility programs?
To make it easy, choose an ENERGY STAR qualifying model and work with a licensed contractor who can help confirm eligibility and handle rebate paperwork.
Can my existing ductwork support a new HVAC system?
The best results come when the ductwork is correctly sized to deliver the airflow a modern, high-efficiency unit needs. If your ducts are older (often 15 to 20 years), leaking, or causing uneven temperatures or higher energy bills, a few targeted repairs or updates can help your new system perform at its best.
A qualified HVAC technician can quickly verify compatibility by performing a duct inspection and a load calculation, giving you clear confidence that your new system will run efficiently and deliver comfortable airflow throughout your home.
How do I know which HVAC brand or system size is right for my home?
As a rough guide, most homes fall in the 1.5-5 ton range (often about 1 ton per 500-600 sq ft), but the load calculation helps ensure the system runs efficiently and maintains consistent humidity and comfort. Once sizing is confirmed, you can compare trusted brands like Trane, Carrier, and Rheem based on your budget, warranty, and efficiency ratings (SEER or AFUE).
