Duct Free Systems

When considering a new heating or cooling system for your home or business explore the numerous benefits offered by a ductless system that may not have crossed your mind.
Ductless heating and cooling systems stand out for their remarkable efficiency. Unlike traditional forced air systems that rely on ductwork ductless systems utilize small individual air handlers directly installed in the rooms they serve. This targeted approach delivers heating or cooling precisely where needed Ensuring a more comfortable living or working environment. Experience the added advantage of reduced energy consumption and lower utility bills.
Ease of installation is another highlight of ductless systems. With minimal reliance on extensive ductwork, these systems can often be installed in just a few hours causing minimal disruption to your home or business. This is particularly beneficial during renovations or expansions when avoiding the hassle and expense of a of new ductwork is a priority.

Duct free heating and cooling systems make your home's individual rooms or other small spaces more comfortable. Remember, just like whole-home systems, the higher the SEER/SEER2 and HSPF/HSPF2 ratings, the more efficient they will be.
The DOE’s regional breakdown by state is as follows:
- North
- 14.0 SEER/ 13.4 SEER2
- 8.8 HSPF/7.5 HSPF2
- Southeast
- 15.0 SEER/ 14.3 SEER2
- 12.2 EER/11.7 EER2
- 8.8 HSPF/7.5 HSPF2
- Southwest
- 15.0 SEER/ 14.3 SEER2
- 12.2 EER/11.7 EER2
- 8.8 HSPF/7.5 HSPF2

SEER/SEER2 And HSPF/HSPF2
SEER2 is an updated rating standard introduced by the DOE. SEER2 standards are intended to provide a better gauge of typical home operating conditions whereas the older SEER rating utilized very precise protocols to determine ratings in ideal conditions. SEER2 standards include updated testing means that give a better indication of how a unit will operate in the real world.
HSPF2 is the newest type of rating system that expands on the basic HSPF scale.
Much like miles-per-gallon for a car, SEER/SEER2, EER/EER2 and HSPF/HSPF2 offer an easy way to compare efficiencies of different products – the higher the rating, the more efficient the unit. Just be sure you are comparing either SEER vs SEER or SEER2 vs SEER2 (same for EER/EER2 and HSPF/HSPF2).
EER2 vs. SEER2
EER2 and SEER2 both evaluate an air conditioner’s energy efficiency, but they’re concerned with two different types of temperature conditions:
- EER2 measures an air conditioner’s efficiency at the peak cooling temperature of 95°F.
- SEER2 measures an air conditioner’s efficiency throughout an entire cooling season, with temperatures ranging from 65°F to 104°F.
