Need a Furnace and AC Replacement Cost Calculator? Mint Home Has Got You Covered

Click here to use our free HVAC tonnage and pricing estimator tool.

Are you wondering how to calculate AC tonnage, get a free online HVAC estimate, or where to find a heat pump savings calculator? Look no further than Mint Home. We provide free HVAC estimate services that utilize AC tonnage calculator results, show the cost of various systems using our new HVAC system cost calculator, and show potential savings you can enjoy when upgrading your system by using our heat pump savings calculator.

AC Tonnage Calculator

Determining the correct unit size is essential for efficiency and comfort. By providing your home’s square footage, our AC tonnage & size calculator will accurately assess the results of our AC size estimator. If your home requires multiple units, our system will factor that in helping you make an informed decision.

A properly sized AC unit ensures optimal cooling without excessive energy consumption. Our online AC calculator helps you find a system that increases the efficiency and comfort of your home. Our tool takes the guesswork out of AC sizing, by providing tailored recommendations based on your home’s specific cooling needs.

AC Size by Square Footage

Not sure what size AC your home needs? While our tool calculates this automatically, here’s a general breakdown that shows how square footage typically aligns with system tonnage.

Home Size(sq. ft.) Estimated AC Tonnage 1,000-1,200 2 tons
1,500-1,800 2.5-3 tons
2,000-2,500 3.5-4 tons
2,600-3,000 4-5t tons

Keep in mind that this chart is just a starting point. Our furnace and ac cost calculator also factors in your region, insulation quality, layout, and other variables to make sure the recommendation is a right fit for your home.

HVAC Sizing Calculator

Using our HVAC load calculator, simply input your home address, square footage, number of floors, and the number of AC units currently installed (if known). Our new HVAC system cost calculator then provides an accurate estimate of the HVAC cost estimator results, ensuring you invest in the right system for your home.

Choosing the right HVAC system is the main contributor to consistent indoor comfort. Ensuring a proper fit allows the HVAC system to run efficiently, reducing energy waste and maximizing savings. An undersized AC unit will have to work overtime, leading to higher energy bills and a shorter lifespan.

What You Need to Calculate When Using the Heat Pump Calculator

Our online system functions as a heat pump cost calculator, heat pump sizing calculator, and a heat pump savings calculator. By entering your home address, square footage, and number of floors, our system will determine the optimal heat pump size estimator result and cost while estimating potential energy savings through local and federal programs.

Selecting the right heat pump is key to maintaining a comfortable home while keeping energy costs low. Our heat pump cost calculator helps you find a system optimized for your home, ensuring efficiency and long-term savings while reducing overall energy expenses. By choosing the right size and model, you can enhance performance, extend the lifespan of your system, and enjoy consistent heating and cooling throughout the year.

What Affects HVAC Replacement Cost?

When it comes to replacing your HVAC system, there’s no one-size-fits-all cost. Our online HVAC quote estimator offers a tailored range based on your inputs, but several real-world factors can influence where your quote lands.

Home size and layout matter most. A two-story house with vaulted ceilings may require more power and potentially more than one system, compared to a single-level layout. Larger square footage typically means higher capacity needs, which increases equipment size and installation scope.
See how to determine your ideal system size here or answer a few questions about your home and receive a quote with your recommended system size.

The local climate plays a big role as well. The U.S. Department of Energy reports that heating and cooling accounts for almost half of a home’s energy use, making the size and efficiency vital to long-term savings.

Your existing ductwork can also affect installation costs. If it’s aging or undersized it may need to be modified to support a newer system.

Higher-SEER or ENERGY STAR® certified systems may cost more upfront but can help reduce energy bills in the long term. To learn more about ENERGY STAR® systems visit their site.

Finally, different system types, like heat pumps, furnaces, or ductless setups, come with different performance profiles and installation requirements. Visit our blog that compares heat pumps to traditional AC and gas setups.

DIY vs. Professional HVAC Installation

Using our HVAC cost calculator not only shows you the price of the system you select but the cost of the installation. Installing a new HVAC system is not a DIY project. It involves electrical wiring, refrigerant handling, ventilation and sometimes gas connections.

Poor installation can lead to reduced efficiency or system failure and not to mention also void a manufacturers warranty. That’s why Mint Home handles every step, our certified technicians install each unit to code, optimize airflow and protect your warranty.

HVAC Replacement FAQs

How do I know what size HVAC system I need?
Our furnace and ac cost calculator uses your home’s square footage, layout, and ZIP code, but factors like ceiling height or insulation can influence the final recommendation.

Do I need to replace my ductwork as well?
Typically, no. If your ducts are in good shape and the correct size they are generally good to reuse. But older or leaky ductwork might need some updating.

Can I get a quote without an in-person visit?
Yes. You can use our new HVAC system cost calculator to generate an online estimate instantly. If you move forward, we will confirm measurements in person ahead of the installation.

How long does the HVAC installation take?
It varies depending on what type of system and how many units you are having installed. On average most installations take typically half to a full day to complete.
