What Affects the Cost to Replace a Furnace and AC?

The cost to replace a furnace and AC, or as some might call it, the cost of HVAC replacement, is influenced by several factors. These include the size of the units, their efficiency ratings, and the type of fuel they use. Bigger units for larger homes typically have higher prices. You can typically expect to pay between $5,000 and $15,000 for a new furnace and AC system in your home.

Units with higher efficiency may have a higher initial cost but can result in significant savings on energy bills over time. The type of fuel or energy source can also influence the overall cost to install furnace and ac units, with different fuel types like natural gas, propane, or electricity each having varying costs. Moreover, the necessary infrastructure for certain fuel types may increase installation costs.

Rebates, tax breaks and other incentives in your area can significantly reduce the cost of your new system. Residents in some areas may soon be able to take advantage of federal HEEHRA rebates to help pay for a new electric heat pump system to replace a gas furnace and AC unit. Learn more about these upcoming federal rebates in our article: HEEHRA Rebate Program: How It Works and When to Expect Rebates in 2025.

Why Replace Your Furnace and AC Together?

Simultaneously replacing your furnace and AC can offer numerous benefits, including improved energy efficiency, comfort, air quality, and potential long-term cost savings. When considering the cost to install furnace and AC units, it's important to remember that modern furnace and AC units are designed to meet strict energy efficiency standards, consuming less energy than older models. By upgrading both systems at once, you can ensure they work together efficiently. Additionally, newer units are more reliable and require fewer repairs, leading to reduced maintenance costs over time. Sears Home Services is here to provide expert advice and top-quality HVAC systems, delivering outstanding performance and long-term value.

What to Consider Before Replacing Your Furnace and AC

There are several factors to consider when you're replacing your furnace and AC unit. These include the age and condition of your current units, the cost and frequency of repairs, and your future plans for the home. If your units are old or frequently need repairs, it may be more cost-effective to replace them. Similarly, if you plan on staying in your current home for a long time, a new furnace and AC can offer long-term savings and comfort. Our expert technicians at Sears Home Services can assess your situation and provide the best solution, ensuring your home remains comfortable and energy-efficient.

Estimated Cost for Furnace and AC Replacement

The cost to replace a furnace and AC can vary significantly depending on various factors. On average, the cost to install a new furnace and AC unit is typically around $8,000 in 2024. As noted above, the cost often ranges between $5,000 and $15,000 for a new system. Factors influencing the final price include:

  • Size of your home.
  • Type of units you choose.

Pros and Cons of Professional HVAC Installation vs. DIY

When replacing a furnace and AC, you might wonder whether to hire a professional or opt for a DIY installation. While a DIY installation might seem cost-effective, it's important to consider the safety implications and potential warranty issues. Professional HVAC installers have the expertise to handle complex installations and offer advice on energy-efficient options. Most importantly, they can ensure the installation is done safely and up to code, and their work often comes with the added benefit of a valid warranty.
