TL;DR
Cost Analysis
MoJo Home Services' free HVAC price calculator gives Denver Metro homeowners a personalized price range for a new air conditioner, furnace, full system, or water heater in about 60 seconds. Enter your ZIP code and home size, compare efficiency options side by side, and see an estimated total and monthly payment built from MoJo's real installed pricing. A licensed MoJo technician confirms your exact price on-site before any work begins.
If your air conditioner quit in the middle of a July heat wave, or your furnace is limping into another Colorado winter, the first question is usually the same: how much does a new HVAC system cost in Denver? It's a fair question, and it deserves a straight answer before anyone shows up at your door.
The trouble is that most numbers you find online are national averages. They don't account for the Denver Metro Area's altitude, local permit requirements, or how homes here are actually built. That's why we built the MoJo HVAC price calculator, a free tool that gives you a personalized price range for your home in about 60 seconds.
At MoJo Home Services, we've been installing and repairing heating and cooling systems across Denver for over 16 years. This guide walks you through what the calculator does, how it works, and how to use your results to make a confident decision.
What the MoJo HVAC Price Calculator Prices
The calculator covers the systems Denver homeowners ask us about most:
Air conditioners: Compare 13, 15, 17, and 20 SEER systems sized to your home.
Furnaces: Choose 80%, 96%, or 97% efficiency, plus single-stage, two-stage, or variable-speed comfort.
Full systems: Price a new AC and furnace together, which usually costs less than replacing them separately.
Water heaters: Standard gas tank, power vent, electric, or tankless, in 40, 50, or 75 gallon sizes.
Mini-splits, boilers, and heat pumps depend heavily on your home's layout, so the calculator points you to a quick conversation with our team instead of guessing.
How It Works: Four Simple Steps
Enter your ZIP code. We use it to match your home to the right climate zone, so your system is sized for Denver weather.
Pick your system and install type. Tell us whether you're replacing an existing system or need a brand new install, which can require extra ductwork or electrical work.
Tell us your home size. Use above-ground square footage only. We use it to estimate the AC tonnage and furnace size your home needs.
Compare your options and see your price. Check more than one efficiency level to see them side by side, then get your estimated total and monthly payment.
Every option has a "Learn more" button that explains it in plain language, so you understand what you're buying before you buy it. When you finish, we email you a copy of your price range and comparison.
Why Our Prices Are Different From Online Averages
Most online cost calculators use national averages that can be thousands of dollars off for a home in Denver. Our calculator is built from MoJo's own installed pricing for Denver Metro homes, the same pricing our team works from every day. That means your range reflects real equipment, real labor, and the way we actually do the job.
Every MoJo installation includes:
Removal and disposal of your old equipment
All gas, electrical, and refrigerant connections
Permits and labor
Thermostat setup and full system testing
Understanding Your Price Range
Your results show a range instead of a single number because no two homes are the same. The low end reflects our most budget-friendly equipment for a home your size. The high end reflects premium equipment for the options you picked.
Where your final price lands depends on details we confirm in person, like the condition of your ductwork, venting, electrical capacity, and how easy your equipment is to reach. A licensed MoJo technician confirms your exact price before any work begins. No surprises, no pressure.
Choosing the Right Efficiency for a Denver Home
Higher efficiency costs more upfront and less every month. Here's how the options compare:
13 SEER: The federal minimum. Reliable cooling at the lowest upfront cost.
15 SEER: The best value for most homes, with lower electric bills and quieter operation.
17 SEER: Two-stage cooling that runs on a gentle low speed most of the day for quieter, more even comfort and better humidity control.
20 SEER: The lowest monthly bills and the best comfort, ideal if you plan to stay in your home for years.
For furnaces, an 80% furnace is the budget-friendly choice, while 96% and 97% furnaces turn more of your gas into heat during long Denver winters. High-efficiency furnaces vent through PVC pipe, so switching from an 80% furnace may require new venting. If you're weighing whether to replace an older system at all, our guide to the HVAC $5000 rule can help.
Monthly Payments and Financing
Alongside your total, the calculator shows an estimated monthly payment based on 180-month financing with no prepayment penalty. It's an easy way to see how a higher-efficiency system fits your budget. Rates, terms, and approval vary by credit, and you can learn more on our financing page.
Built for Homeowners, Not Sales Pressure
We built the calculator around one idea: educate first, recommend second. You can explore every option on your own time, compare them side by side, and get answers without a salesperson in your living room.

Frequently Asked Questions
How accurate is the MoJo HVAC price calculator?
The calculator is built from MoJo's real installed pricing for Denver Metro homes, so it's far closer to what you'll actually pay than national averages. Your exact price depends on details like ductwork, venting, and electrical capacity, which a licensed MoJo technician confirms on-site before any work begins.
Do I have to give my contact information to see prices?
At the end, we ask for your name, email, and phone so we can email you your personalized price range and side-by-side comparison. We only reach out about your estimate. No spam, no pressure.
Why does the calculator ask for above-ground square footage only?
Basements in Denver homes stay naturally cool and usually aren't part of the main heating and cooling load. Including basement square footage can oversize your system, which leads to short cycling, uneven comfort, and higher bills.
Does the price include add-ons like humidifiers or UV lights?
You can add optional upgrades like a whole-home humidifier, UV air purifier, smart thermostat, media filter, or surge protector. They're priced separately, so you can see the cost of your system on its own and decide what's worth adding.
Can I get a price for a mini-split, boiler, or heat pump?
Those systems depend heavily on your home's layout, zoning, and existing infrastructure, so an on-site assessment is the only way to give you an accurate number. Call or text 720-807-4050 and we'll set one up.
