Comfort Air Conditioner
Single-stage cooling. The dependable, straightforward choice.
Cooling equipment is graded by efficiency and by how precisely it can modulate. Both matter, but not equally for every house.
Single-stage equipment is either fully on or fully off. It is the cheapest to buy and perfectly adequate in a well-built, correctly ducted house. Two-stage runs at a lower output most of the time, which means longer, gentler cycles and noticeably better humidity control. Variable-speed modulates continuously and is the quietest and most comfortable, at a higher price.
The efficiency rating — SEER2 — tells you how much cooling you get per unit of electricity under standard conditions. Higher is better and costs more up front, so the right choice depends on how long you will own the house and how hard you run the system.
All of this depends on equipment that is the right size and ductwork that can carry the air, which is why we measure first.

Single-stage, two-stage or variable-speed?
Cooling equipment is graded by efficiency and by how precisely it can modulate. Here is how the three compare on modulation.
Single-stage
Comfort Series- How it runs
- Fully on or fully off
- Cycles
- Full output, then off
- Humidity
- Adequate in a well-built, correctly ducted house
- Choose it when
- You want the dependable, straightforward choice
Two-stage
Performance Series- How it runs
- A lower output most of the time
- Cycles
- Longer, gentler cycles
- Humidity
- Noticeably better control
- Choose it when
- Humidity is your main concern
Variable-speed
Infinity Series- How it runs
- Modulates continuously
- Cycles
- Long, gentle cycles instead of starting and stopping at full output
- Humidity
- The best at holding it steady
- Choose it when
- The house feels clammy, or quiet matters most
Whichever you choose, we size it by load calculation and check the ductwork first.
What to look for
What matters when you choose
Right-sized by load calculation, not by matching the old unit
Matched indoor and outdoor units for the rated efficiency
Ductwork assessed before the equipment is quoted
Two-stage or variable-speed where humidity is the complaint
Ductless options for additions and problem rooms
Airflow measured and set at commissioning
The equipment matters less than how it is sized and installed, and that part is our responsibility.

Common questions
What SEER2 rating should I buy?
It comes down to payback. Higher efficiency costs more up front and returns it over years of running. If you plan to stay twenty years, buying up usually makes sense. If you expect to sell in three, the extra cost will not come back.
Is variable-speed worth the money?
For humidity and quiet, yes — it runs long gentle cycles instead of blasting and stopping. For pure running cost, the gap is narrower. If your main complaint is that the house feels clammy, it is the right answer.
