Keller's "Peace of Mind" Quality
Tight Construction
Air sealing the building envelope is one of the most critical features of an energy efficient Keller Home. Caulking, foaming, and gasketing of holes and gaps in the home helps reduce energy loss, which lowers utility bills for heating and cooling. Reduced air infiltration in walls and floors also helps prevent moisture and mold problems.

Green Fiber Cellulose Blown-In Insulation
  R-38 in the attic and R-13 and R-20 in the walls helps keep our homes comfortable and quiet. Insulation is installed without any gaps, compressions, and misalignments. This continuous boundary of insulation between the inside and outside helps our homes maintain temperature efficiently.

Air Barrier
  To insure that air penetration into the home and at the insulation is minimized wall sheathing is installed as an air barrier in hard to reach areas on both sides of insulated walls including attics, fireplace chases, and bath tub walls. This helps the heating/cooling system to perform as designed.

Duct Sealing & Insulation
  Ducts carry air from a home's central heater or air conditioner to each part of the home, but can waste a significant amount of energy due to improper installation and poor materials. At Keller Homes we seal our ducts improving the comfort and air quality of our homes, while reducing utility bills.

Sealed Combustion Water Heater
Each Keller Home is equipped with a sealed combustion water heater that decreases the possibility of potentially harmful carbon monoxide, nitrogen oxides and water vapor from entering the home. Faster recovery time will increase availability of hot water and higher performance will lower utility bills. Because you have faster recovery you can reduce the size of the water heater.

Manual J Calculations
Standard sizing of HVAC equipment often results in a mismatch, sizing the air conditioner by simply applying tonnage to square footage is not acceptable anymore.

Manual D Calculations
Manual D Calculations are the technical specifications for heating and cooling a home. Quality HVAC contractors perform these calculations to ensure comfort and performance.

Advanced Low-E Windows
Heat gain and loss through windows can account for up to 50% of a home's heating and cooling needs. Low-E Windows let light in and reflect heat back out, making your Keller Home more comfortable and protecting interior finishes from fading.

High Efficiency Heating & Cooling Equipment
Heating and cooling systems that are highly efficient save 10 - 40 percent on heating and cooling bills while improving the comfort level in a home. Keller Homes installs 92% AFUE furnaces to ensure lower energy bills.

Energy Efficient Inspection
Each Keller Home is individually inspected and tested for energy features by a Certified Home Energy Rater. The efficiency of all equipment, building components, house tightness, and duct tightness are verified to meet the stringent standards of the Environmental Protection Agency.
