How Much Does a New HVAC System Cost?
The honest answer is that it depends — but that's not an excuse to dodge the question. Here's what actually moves the number, and what to look at before you compare two quotes.
The starting point
Our new systems start as low as $7,995. That's a real entry point, not bait. Where your project lands depends on the equipment you pick and what your house needs to accept it.
What actually moves the price
- Equipment type — a gas furnace and AC pairing prices differently than a heat pump
- Capacity and efficiency of the system you choose
- The condition of your existing ductwork, and whether it needs correcting
- Electrical work, if the panel or circuit needs attention for an all-electric system
- Access — attic, closet, crawlspace, or roof changes the labor involved
- Permit and HERS requirements for your project
Why two quotes rarely match
One quote might include duct corrections, permit handling, HERS testing, and a 10-year labor warranty. Another might cover the box and the day's labor. Comparing the totals without comparing the scope is the single most common way people end up disappointed six months later. Normalize the scope first, then compare.
Questions worth asking any contractor
- Is the permit included, and will you handle HERS if it's required?
- What's the labor warranty, and who honors it?
- Did you look at the ductwork, or just the equipment?
- Is this sized from a load calculation, or matched to what's there now?
- What exactly is excluded from this price?
What's included when we do it
- 10-year parts and 10-year labor warranty
- Lifetime Workmanship Guarantee while you own the home
- Permit process, and HERS when required
- Inspection coordination
- Manufacturer warranty registration filed for you
- Upfront pricing before any work begins
What we're not going to guess at
We deliberately don't publish price ranges by system size or brand here. Anything beyond our $7,995 starting price is specific to your home, and we'd rather quote it than guess at it.
