The Decision In A Nutshell:
Like most homeowners, if you've done any research online you may be feeling a little overwhelmed; even frustrated. There's loads of technical details; enough to make your eyes glaze over. Let's see if we can simplify, in general terms, what is involved in making the right decision for you. We hope this helps.
Let's frame the decision in simplest terms. Let's use the familiar 'Good, Better and Best'.
In this graph you see, the more you invest the greater TRUE comfort, efficiency, the quieter it operates and the better air quality.
Keep in mind you're making this decision one time and living with it for 20 years. It makes no difference to us which one you select.
Here's a little more about the specifics to help you understand and the variables that determine a move up or down and the corresponding investment ranges. We'll begin by keeping the AFUE at 95/96%.
Two variables to determine:
- #1 determine the BTU's (size) - By the Manual J Software and the heat loss calculated of your home.
- #2 Which airflow system to chose:
- Single Stage (Standard)
- 2-Stage (Deluxe)
- Variable (Premier)
- Modulating (Optimum)
To illustrate, let's compare an on/off light switch to a dimmer switch commonly found in many kitchen or dining rooms, where you can adjust it to almost unlimited brightness vs. on/off.
Here's A Building Scientist's Opinion:
"What many home owners don't realize is that a unit uses more energy in the first three to five minutes ramping up compressors and coils than in the next 25 minutes of continuous running," Most homeowners think just the opposite". A single-speed furnace or air conditioner comes on full-blast no matter what. That may be okay in the dead of winter or heat of summer, but in the spring or fall, when outdoor air temperatures are less extreme, a single-speed unit may heat or cool rooms too quickly.
Keep in mind the Vredevoogd Comfort Guarantee - The system we install will heat or cool as we have stated. If the temperature range we have promised is not achieved, we will replace the system at no charge.
