Calculated & Guaranteed Heating & Cooling Bills

  • Each home is sent off to ex-NASA engineers to analyze and determine what the guaranteed monthly heating and cooling cost will be, based on all building factors and techniques of Excel Builders and the particular home.

2-10 Home Buyers Warranty

At Excel Builders, we stand behind all of our work. Additionally, all of our homes come standard with a 2-10 Home Buyers Warranty, the best home warranty in the industry:

  • 1 year workmanship warranty
  • 2 year mechanical systems warranty
  • 10 year structural warranty

Geothermal Heating & Cooling System

  • The standard heat pump of our choice is the most efficient type of heat pump that is on the market. Geothermal uses the earth’s energy to reduce your heating and cooling bill every single day.

Fresh Air System

  • Clean air is extremely important for a healthy and comfortable indoor living environment. The high performance fresh air system continuously replaces stale indoor air with fresh outdoor air

Whole House Salt-Free Water Softener & Water Purification System

  • Live healthier without all of the chemicals and additives in your water with a whole house water filter and softener. The water coming from your tap will be better than bottled water and you’ll notice softer skin, hair, and many other benefits. This system ensures that the water in your home is the best water you can provide to your family.

Rinnai Tankless Instant Hot Water Heater

  • Never worry about running out of hot water with a Rinnai tankless water heater. This water heater saves energy by only heating water when needed, compared to traditional tank-style water heaters which heats and reheats water all day long.

Fully Conditioned Crawlspace

  • We fully encapsulate the crawl space, seal up everything, and provide ventilation and dehumidification systems. This ensures maximum efficiency, while providing a very clean crawl space.

Low-E Argon Gas Windows With Unmatched Efficiency

  • Dual glazed, low-E with argon R-5 windows throughout the house allow for window energy efficiency that is off the charts for standard windows. Our standard windows have a U-Factor of 0.22, which stand well above average windows in the industry.
