Questions and Answers

I’ve had it with high energy bills. How can I ensure that my new custom home provides lower energy bills?

Many factors can contribute to the cost of your electric bill each month, but if you’re continually experiencing sky-high prices your HVAC system could be the culprit. If your HVAC system in your new home is not designed, installed, or sized properly, then high energy bills may continue to be in your future. The installation of an HVAC system, including the insulation and duct work, is typically handled by multiple contractors, creating room for oversight and error.

How do I ensure the HVAC system in my new home will be installed correctly?

Approximately 50 percent of HVAC systems are not installed properly, and an estimated 70 percent of HVAC systems are insufficient and headed for a break down. An incorrectly installed HVAC system in your new home can lead to higher energy costs and lower air quality. A reliable HVAC design and quality control partner, such as SED, will have the experience, tools and technology to gather the right information, perform the correct analysis and implement the necessary changes to ensure that your system is functioning properly.

How can I be sure I’m investing in the right HVAC system, and what are the most important considerations?

Energy savings and air quality are two of the most important factors to consider when evaluating a new HVAC system. By investing in an advanced HVAC system design, you can expect elevated performance for these two components and look forward to enjoying a comfortable, healthy living environment along with recurring cost savings. Most contractors will tell you that energy efficiency will be part of your home’s design and construction, but how will you know that they are using the best available solution? SED’s design and analysis approach is proven to create the highest air quality available, and they even guarantee that their HVAC system will maintain that quality for the entire life of the home.

After talking with your designer/architect and your builder and asking the right questions, be sure to get a proper HVAC Design Analysis. Ask for real-life examples of customer’s energy bills during your decision-making process. Talk with your banker to ensure you’re spending the right dollars on your investment and that you’re financing to produce an ROI on your HVAC system. If your initial HVAC analysis is performed correctly, the numbers should start to speak for themselves. On average, our advanced HVAC systems deliver a 10 percent return on your investment!

How can I ensure my new home is energy efficient?

Efficient or green construction is a trend that keeps growing in the home building industry, as consumers expect more from a new home. While there are many concepts tied to this ideology, energy efficiency is at its core. When designed correctly, a custom home should provide maximum energy savings, air quality, and comfort in your living environment. In fact, by investing a bit more up front in an energy efficient HVAC system design, you can save up to 60 percent on the monthly energy cost to heat and cool your home . So, how can you ensure you’re taking the right steps when designing your new dream home?

Start by asking your builder for specific information on your climate control, such as: Who will design my HVAC system? What kind of HVAC products do they plan on installing? How do they plan on tracking the quality of the installation? Do they guarantee results?

By asking the tough questions and doing your research, you’ll be on your way to building a truly efficient home that’ll pay dividends and ensure you enjoy comfortable, pure air every day.

What steps do I need to take before selecting an HVAC system for my new home?

Selecting an HVAC system could be one of the most important decisions you make during the home building process when it comes to long term costs and comfort. To ensure you set yourself up for success, make sure to follow these three steps during the selection process:

  1. Do your background research. Talk to an expert, learn about your different options and ask the tough questions about the installation process. Most people who don’t take this initial step wind up with an HVAC system that isn’t sized correctly for their home, resulting in an inefficient system and increased costs. By performing the proper analysis and research upfront you can save big long-term.
  2. Walk through the analytical report with an HVAC expert. As a new homeowner, you will be required by law to receive an analytical report but make sure you really understand it before you select an HVAC system.
  3. Partner with an HVAC design expert, like SED, that utilizes the most current technology methods to determine the energy loads, the anticipated equipment costs, and guaranteed energy utilization for your new HVAC system.

How can I make sure I have the highest air quality in my new custom home?

Did you know that outside air is 10 times cleaner than the air we breathe inside our own homes? And that the average person spends 90 percent of their life indoors breathing this air? The key to maintaining clean and healthy air in your home is to have a constant flow of air in your HVAC system. If air is not circulating every 15 minutes, you are creating the potential for bad air, which can result in moisture problems promoting mold growth and exacerbating allergies. With the proper air flow and filtering system you can not only improve the quality of the air in your home, but you can also improve your health.
