Systems
Systems we change out
Each one has a written quote, a permit and an install day. What changes the number is listed under each.
Air conditioner and furnace, as a pair
The classic split system, replaced together so the coil, the air handler and the thermostat match.
Tonnage from a load calculation
Efficiency tier and staging
Duct condition
Permit and haul-away
Heat pump with a gas furnace behind it
A dual-fuel system. The heat pump runs most of the year, and the furnace takes over on the coldest nights.

Furnace input and venting
A thermostat that switches between them
Electrical and permit
Heat pump and air handler, all electric

Permit
Package unit
One cabinet that holds everything, set beside the house or on a slab. Common on homes with no attic or closet for an air handler.

Ducts and a thermostat during the changeout
While the old system is out, leaks, kinks and missing returns are cheap to fix. We show you what we find before we change the quote.
Sealing with mastic
Return air changes
Insulation at the plenum
A thermostat you can read
Questions
Picking a system
How do I know what size I need?
We calculate it from your house: rooms, windows, insulation and ducts. It is a calculation, not the size of the old unit, and it is written on your quote.
Should I get a heat pump?
In Charlotte winters a heat pump can heat most of the year. Whether to keep a gas furnace as backup depends on your house and your bills. We show both options on one quote.
How long should a system last?
It depends on the equipment, the installation and the care it gets. A system that needs a second repair in a season is worth pricing a replacement for, and we say when it is not.
Not sure what you have?
Text us a photo of the label on the outdoor unit and we will tell you what it is.
